There are a number of initiatives coming about that affect energy users and show that demand reduction is at last being taken seriously, even if it is still very much a secondary thought after supply side concerns. Water, Energy & Environment has undertaken a timely research paper that examines current attitudes to energy efficiency with particular emphasis on the piece of government legislation ESOS – Energy Saving Opportunities Scheme. This is the UK’s implementation of article 8 of the EU Energy Efficiency Directive and requires all companies that are not SMEs to undertake a mandatory audit by December 2015 and every four years thereafter. Copies of the survey are available at theenergyst.com ESOS has come into force and many organisations have not yet decided how best to tackle the issue. Exemption is provided by a number of routes such as ISO 50001 but time is of the essence, qualification ends in December this year with full compliance required by December 2015. The biggest concern for the scheme as a whole is to ensure that it is not just another tick-box exercise leaving reports gathering dust on the bookshelves of UK industry.

The survey highlighted the fact that finance is still the number one barrier to energy efficiency but since our last survey this is reducing. There are many options around that enable investment in technology that can be paid for by the savings and this this may be starting to have an effect or it may just be the recovery from the recession. The DECC’s Electricity Demand Reduction (EDR) pilot is making £20m available to support projects that deliver lasting reductions in electricity demand.

This pilot will test whether EDR could participate in GB’s capacity market. Projects will bid into an auction and commit to delivering a kW saving, successful bids secure funding, that can then be used to support the installation of more efficient electrical equipment. If will pay the difference that helps make a project viable for a business. So if reducing a five-year payback to three was acceptable the EDR scheme would pay the difference in these two calculations. There will be a minimum bid size of 100kW in the auction. This may be achieved by a single project or through several projects, aggregated into a single application. See page 10 for further details of what EDR is and how you could get involved.

Our survey also showed that board level engagement as a barrier has dropped by a third, which is encouraging in that it sets the tone for a whole organisation that saving energy is a worthwhile objective. This is corroborated by the survey wherein 68% of end users do not see energy just as a burden but as an operational resource that can be migrated against. The tide may be changing and the largely untapped potential of energy efficient UK businesses may well be realised. Let’s hope so.

Electricity system operator National Grid is to tender for two new services to help balance supply and demand in the coming winters.

The move follows a call for expressions of interest earlier this year, a consultation on the two services and approval from Ofgem in 2013.

National Grid is currently tendering for up to 330MW Demand Side Balancing Reserve (DSBR) for winter 2014-15; and will tender by autumn 2014 and in early 2015 for a total of up to 1,800MW of both DSBR and Supplemental Balancing Reserve (SBR) for winter 2015-16.

These services will help ensure the country continues to benefi t from high levels of system security.

The DSBR is looking to sign up large energy users that have the fl exibility to reduce their electricity use – for example by switching to back-up generation – when demand is at its highest between 4pm and 8pm on winter weekdays. This will be in return for a payment, and on a purely voluntary basis.

Such a move will help stimulate a Demand Side Response (DSR) market, which ultimately will help keep energy system costs

down for consumers by avoiding the need to build additional power stations to service peak demands.

National Grid already buys similar demand-side services from a range of businesses, and many large businesses already reduce their electricity usage in peak demand periods to reduce their costs.

Supplemental Balancing Reserve (SBR) is targeted at contracting for reserves from generating plant that would otherwise be closed or mothballed. Plant would need to be available on winter weekdays between 6am and 8pm.

The maximum volume needed for the coming winters is set out as follows:2014-15 – 330MW (DSBR)2015-16 – 1800MW (DSBR and SBR)2016-17 – 1300MW2017-18 – 800MW

Tenders for the winters of 2016-17 and 2017-18 will only be undertaken if an ongoing need for these services is identifi ed and the funding arrangements are extended beyond 2016 by Ofgem.

It is not anticipated that these services will be required in 2018-19 because the government is introducing a capacity market.

Why don’t suppliers fill the account management role?A lot of our contacts at supply companies would make great account managers. At the same time, they don’t have the same level of empathy that we do with our clients. When you have hundreds of accounts to manage you simply can’t provide this. We have no restrictions on what we can do. One of our directors likes to remind us that he once sat on the side of a road from 8am to 1pm waiting for a meter installer who had missed the last two appointments to connect a large digital screen on the Euston bypass. On a day to day basis we’ll attend meetings at short notice, quickly turn around research and even support bids clients need help on. Our clients are dynamic and we need to be dynamic in our response. Larger corporates have layers of tape that restricts their speed and ability to think out of the box.

Where do clients need the most support?It varies from client to client but all clients tend to need help with metering and AMR issues. This is because suppliers pass this work to third parties and whenever that happens the client loses visibility. So we spend a lot of time chasing down those contractors and making sure they keep to schedule.

A day in the life of an account manager

We also provide a lot of reporting in the form of budgets, usage, billing and trading results. We found that the best way to provide this information is on a monthly basis in one reporting suite. Not everyone requires it monthly but everyone knows that each month they will have this should the need arise.

What’s the most rewarding thing you’ve done?I am really interested in technology (geek!) and for the past six months we’ve been building a new online reporting system that client can access to retrieve bills, budgets, usage data and market news. Working on something like that from the feet up is really rewarding and something to be proud of. As we have always done things our own way it felt right to do the same with this rather than buy something off the shelf and shoe horn it into our clients.

Who would be your dream client?I studied Culture & Art at university so someone like the National Gallery or British Museum would be. The good thing about our job is that we need to understand the client’s working patterns and therefore energy usage patterns. This involves getting to know their culture and practices on a deeper level so understanding the ins and outs of museum/gallery life for me would be cool.

Delivery of leading account management services is helping the way we perceive energy brokers and consultants. we asked Charlotte Fowler, head of account management at Pulse Business energy, to explain why

The UK’s energy market “does not work” and market intervention is therefore needed to ensure that low-carbon energy generation and security of supply are properly valued. That’s according to the head of the country’s transmission system operator.

Speaking in London in June, National Grid ceo Steve Holliday told the UK energy 2014 meeting that the UK government’s electricity Market Reform package is “the right intervention at the right time.” Mr Holliday said it would address the twofold

challenge currently facing the electricity market: firstly, “the energy market today does

not value low carbon”, and “secondly, it is crystal clear that very few markets place a true value on security of supply”.

one of the main mechanisms of the reforms is the contracts for Difference (cfD) scheme, which is designed to encourage investment in low-carbon technologies, including nuclear, by guaranteeing future revenue streams and thereby reducing risks to investors.

Speaking at the same event, eDF energy ceo Vincent de Rivaz referred to the ongoing state aid investigation by the european commission

into the terms of the cfD negotiated between eDF energy and the government for the proposed Hinkley Point c nuclear power plant.

He said that his company has “a strong case” and claimed that the proposal is compliant with all the state aid rules of the european Union.

Mr De Rivaz noted that member states have the right to choose their own energy mix and that Hinkley Point c would help address the challenges of security of supply, climate change and affordability.

emR is the ‘right intervention at the right time’“It is crystal clear that very few markets place a true value on security of supply”

energy minister michael Fallon descended into the science & technology Facilities council’s Boulby Underground Laboratory – the UK’s deep underground multi-disciplinary science facility housed in Britain’s deepest mine – on 13 June to witness a milestone in the search for solutions to the problem of carbon emissions.

mr Fallon visited cutting-edge particle detectors that are being developed to determine the quantity and distribution of rock structures overhead (the overburden) from deep underground. this capability could remove a big barrier to the introduction of carbon capture and storage (ccs) technology by making it possible to monitor co2 fed into depleted oil and gas fields and so ensure it is being stored securely.

Development of the detectors is the focus of a £1.7m project funded by the Department of energy & climate change and Premier oil. the consortium delivering the project includes the universities of Durham, sheffield and Bath,

cleveland Potash, Premier oil and stFc, with NAsA also providing input.

Located 1.1km down in the workings of Boulby mine on england’s north-east coast, Boulby Underground Laboratory is run by stFc in partnership with cleveland

Potash, the mine’s operators. the detectors now being built and commissioned there detect muons – charged particles produced when cosmic rays from distant supernovas strike the atmosphere. the particles then shower downwards before penetrating several

kilometres into the earth. one of the detectors, located

in a “gallery” extending out under the North sea, will use these muons to monitor the change in overburden due to the movement of tides taking place more than half a mile overhead. this will provide a first proof-of-principle for the overburden measurement and imaging technique, known as “muon tomography”. the minister also saw a smaller, more sophisticated prototype specifically designed to fit into oil and gas boreholes through which co2 would be fed.

mr Fallon said: “It is fascinating to see how the innovative co2 monitoring technology being tested at Boulby could help to reduce the costs of carbon capture and storage.”

the current method collects seismic data – an expensive option that only produces snapshots of what is happening. muon detectors can conduct non-stop monitoring and cut annual monitoring costs from about £300m to £60m per repository, making ccs more viable.

More than a million english businesses will be able to choose their water supplier for the first time after new legislation was passed to bring competition to its £2bn market.

The Water Bill was granted Royal Assent on 14 May, providing english non-domestic customers with choice over their water supplier, with the aim of improving customer service and water efficiency.

In Scotland, the non-domestic water market opened to competition in April 2008, and since then customers have saved more than £36m from their water bills by reducing the volume of water they use. More than £30m of discounts have also been taken up by customers.

Mark Powles, chief executive of Business Stream – a Scottish-based water services company that already operates in england

England’s water market to open to competition– said the legislation would force water companies to improve their services towards customers or face losing market share.

The new market in england is scheduled to open to all customers in April 2017. At the moment, only the very largest users of water – sites consuming more than 5 million litres a year – can switch supplier.

Mr Powles said: “The important point about retail competition is that what happens at a network and infrastructure level shouldn’t affect the service the customer receives at the retail end. If this market is successful then in a few years we’ll hear customers saying they’re getting a better deal than they are now, that they’re more aware of the role water plays in their businesses, and they feel more in control of the service they receive.”

The government is in support of a greenhouse gas emission reduction target without a binding renewables target. Signing up to yet more greenhouse gas emission targets, irrespective of the impact on consumers and business, would be deeply irresponsible, says energy minister Michael Fallon.

Speaking at eurelectric’s annual conference, he said talk of the trilemma that posits security, affordability, and decarbonisation at opposite points of the triangle is “false geometry. Without secure, affordable energy we will not be able to move to a more sustainable, lower carbon energy future.”

Mr Fallon added that the framework for 2030 must be a driver for competitiveness and resilience that secures investment in a diverse and low carbon technology base.

False geometry for Fallon

The energy Saving opportunities Scheme (eSoS) has been launched by Decc (26 June). It affects all businesses that are larger than SMes; greater than 250 staff, a turnover of £42.5m and a balance sheet of more than £36m; and requires them to conduct a manatory audit by December 2015 and every four years thereafter.

A recent eSTA conference chaired by Tim McManan-Smith provided a number of contrasting views on the subject.

Many agreed that it would at the very least raise the profile of energy saving among larger organisations and get the attention of the board. Lisa Gingell, t-mac Technologies director and eSTS board member, commented: “In essence, the legislation is

beneficial in the fact that it puts more audits in place, which will in effect raise awareness within business of opportunities for energy improvements.

“However, where we believe eSoS is lacking is in its efforts to influence businesses go to the next level. encouragement to physically implement the

proposed solutions and changes isn’t part of the legislation. A lack of “full-circle” energy thinking to get businesses to act on the data collected and make the change to see the savings in energy costs and carbon emissions is where eSoS may fail to make an impact.”

It was pointed out by some delegates that although there is no explicit requirement to enact any of the measures created by mandatory auditing it does have to feature within annual reports and therefore progress can be monitored via these. In effect it would look bad if a company were moving backwards or making little progress.

Water Energy & Environment has surveyed views of energy efficiency in general with a particular look at attitudes to eSoS and ISo50001. To get a copy go to theenergyst.com

esos will help to raise profile of energy savings among large businesses

currently england’s water market is split into regional monopolies, with the existing market structure allowing very little scope for customers to exert pressure on suppliers to tailor the services they provide.

Under the competitive market, though, a business with several sites across the

country could switch all of them to one supplier, benefiting from associated economies of scale across billing and administration, as well as driving significant value from services like water efficiency initiatives and trade effluent management.

Mr Powles said: “This shouldn’t be about Royal Assent and then nothing for three years. We’ve spoken to lots of customers who don’t feel as if they’re getting value from their regional suppliers, but can’t do anything about it.

“This legislation should be seen as an opportunity for customers to put themselves in the driving seat now, so that when competition does kick in, they’re in a position to know exactly what they want and expect from their water company – and that’s bound to be more than just a bill.”

“This should be seen as an opportunity for customers to put themselves in the driving seat now”

offshore wind is on course to meet 10% of UK electricity demand by 2020, according to The crown estate, manager of the UK seabed.

It has published two reports at this year’s Global offshore Wind 2014 conference painting a picture of an industry maturing and on course to double its capacity by 2020 to 10GW or more – about 10% of the UK’s electricity demand.

Offshore wind operational report 2014 highlights the sectors continuing growth, while Sharing lessons learned and good practice in offshore transmission sets out a pathway to cost reduction which will help

unlock the sector’s potential. commenting in the report,

the secretary of state for energy and climate change

ed Davey said: “The UK is the number one country in the world for offshore wind, supporting green jobs and growth as well as strengthening our energy security. We have already attracted over £30bn worth of investment in renewable technologies since 2010. our ambitious electricity market reforms provide investors with the long-term certainty they need.”

Huub den Rooijen, head of offshore wind at The crown estate, said: “With around 1,465 wind turbines in operation or under construction and nearly 4GW in operation it is fair to say the industry is coming of age.”

offshore wind is ‘coming of age’

A survey has revealed that 56% of UK citizens would trust the energy sector more if it were back under state control. continued low levels of trust in the UK’s energy industry could be remedied by an increase in government intervention in the market, according to new analysis from edelman’s 2014 Trust Barometer.

More than half of UK citizens polled (56%) would trust the industry more if it were returned to state control, with only 18% stating they trust it more as a privatised industry. Nearly three-quarters (73%) called for additional government regulation.

Trust in energy in the UK, which has fallen to 31%, is lower than anywhere else globally. This marks a decrease of 6% on 2013 levels, making it the least trusted industry – even below banking. 82% of those that reported lower levels of trust this year attribute the drop to the increasing price of household electricity bills; while levels of industry profit were also among top reasons cited. 41% of respondents also said the ongoing debate on the cost of living was likely to impact trust in government over the course of the next year.

Underlining the extent of the challenge facing both government and industry, the UK has the least trusted energy sector (31%) of any global energy market, with the global average being 28 points higher (59%).

The poll also revealed that the public wants the energy industry to be a more active participant in the broader debate around energy policy (65%), including providing improved products and services and making structural changes to the industry.

Renationalise if you want trust

energy regulator ofgem has called on the Big Six energy suppliers to explain to their customers what impact falling wholesale costs will have on their energy prices. In a letter to the large suppliers, ofgem outlined that failure to engage with consumers on this issue further risks undermining public confidence in the energy market if wholesale costs continue to fall.

In recent months, both wholesale gas and electricity prices have been falling significantly. In early June, gas prices for next-day delivery reached their lowest level since September 2010 and are now about 38% below this time last year. The trend has been similar in electricity, with prices reaching their lowest level since April 2010 at the beginning of June. They are currently about 23% lower than this time last year.

While there are upward pressures on energy costs resulting from government schemes to support environmental objectives as well as energy network

renewal, the costs of wholesale power and gas cost dwarf these and make up just under half the total bill.

Forward prices for gas and electricity have also fallen. compared with last winter, gas and electricity prices for the coming winter are about 16% and 9% lower respectively than last year. This trend has been driven by the mild temperatures across GB and europe last winter, leaving gas storage at record levels.

In a competitive market the threat of losing market share would encourage suppliers to reduce their customers’ bills whenever there are sustained reductions in costs. Suppliers are yet to reduce their prices for existing customers to reflect the wholesale cost changes.

ofgem chief executive Dermot Nolan said: “The Big Six suppliers tell us that they think the market is competitive but our research shows that consumer trust is low. Therefore if suppliers are going to start rebuilding that relationship they need to take the initiative and explain clearly what impact falling wholesale energy costs will have on their pricing policies.

“If any of the companies fail to do this, consumers can vote with their feet. Independent suppliers are currently offering some of the cheapest tariffs on the market.

Speaking at eDF energy’s TalkPower event, MrNolan suggested that prices rise like a rocket and fall like a feather. eDF energy’s ceo Vincent de Rivaz agreed that this is the percieved wisdom but that it isn’t very wise.

ofgem is currently proposing referring the retail market to the cMA after a joint report with the oFT and cMA confirmed that competition is not working as well as it could.

This marks a decrease of 6% on 2013 levels, making it the least trusted industry – even below banking. 82% of those that reported lower levels of trust this year attribute the drop to the increasing price of household electricity bills; while levels of industry profit were also among top reasons cited. 41% of respondents also said the ongoing debate on the cost of living was likely to impact trust in government over the course of the next year.

Underlining the extent of the challenge facing both government and industry, the UK has the least trusted energy sector (31%) of any global energy market, with the global average being 28 points higher (59%).

The poll also revealed that the public wants the energy industry to be a more active participant in the broader debate around energy policy (65%), including providing improved products and services and making structural changes to the industry.

Renationalise if you want trust

energy regulator ofgem has called on the Big Six energy suppliers to explain to their customers what impact falling wholesale costs will have on their energy prices. In a letter to the large suppliers, ofgem outlined that failure to engage with consumers on this issue further risks undermining public confidence in the energy market if wholesale costs continue to fall.

In recent months, both wholesale gas and electricity prices have been falling significantly. In early June, gas prices for next-day delivery reached their lowest level since September 2010 and are now about 38% below this time last year. The trend has been similar in electricity, with prices reaching their lowest level since April 2010 at the beginning of June. They are currently about 23% lower than this time last year.

While there are upward pressures on energy costs resulting from government schemes to support environmental objectives as well as energy network

renewal, the costs of wholesale power and gas cost dwarf these and make up just under half the total bill.

Forward prices for gas and electricity have also fallen. compared with last winter, gas and electricity prices for the coming winter are about 16% and 9% lower respectively than last year. This trend has been driven by the mild temperatures across GB and europe last winter, leaving gas storage at record levels.

In a competitive market the threat of losing market share would encourage suppliers to reduce their customers’ bills whenever there are sustained reductions in costs. Suppliers are yet to reduce their prices for existing customers to reflect the wholesale cost changes.

ofgem chief executive Dermot Nolan said: “The Big Six suppliers tell us that they think the market is competitive but our research shows that consumer trust is low. Therefore if suppliers are going to start rebuilding that relationship they need to take the initiative and explain clearly what impact falling wholesale energy costs will have on their pricing policies.

“If any of the companies fail to do this, consumers can vote with their feet. Independent suppliers are currently offering some of the cheapest tariffs on the market.

Speaking at eDF energy’s TalkPower event, MrNolan suggested that prices rise like a rocket and fall like a feather. eDF energy’s ceo Vincent de Rivaz agreed that this is the percieved wisdom but that it isn’t very wise.

ofgem is currently proposing referring the retail market to the cMA after a joint report with the oFT and cMA confirmed that competition is not working as well as it could.

The UK’s Green Investment Bank has announced its 2013-14 results and revealed plans for a new £1bn fund.

With 18 months of activity so far, the majority of GIB’s investments (88% by value) remain in construction and, in line with standard accounting practice, a significant proportion of income is deferred to future years. GIB recorded an operating loss of £5.7m in the current year but is on track to reach sustained profitability once its current portfolio is built and operating.

GIB has also announced plans to launch a £1bn fund to acquire equity stakes in operational offshore wind projects in the UK. GIB is seeking a suitable group of strategic, long-term co-investors to participate in this capital raising exercise. The fund will be managed by a GIB subsidiary, which is currently regulated by the Financial conduct Authority (FcA) and will be seeking permission

from the FcA to become a regulated fund manager.

To support that growth, it is vital that developers – typically large utilities – are able to refinance part of their investments in operating assets to reinvest in new developments. This requires a significant broadening of the number of long-term investors in UK offshore wind projects.

In May 2014, GIB received State Aid approval from the european commission to promote and manage funds and other co-investment structures for mobilising upfront private sector investment into its designated sectors. This widening of GIB’s activities will enable it to promote and manage funds and all other types of structured co-investments within any of its designated green sectors, allowing it to raise and deploy private sector capital in addition to its current £3.8bn of equity funding from the UK government.

UK Green Investment Bank reveals plans for £1bn fund

the end for large scale solar?The Department for energy & climate change has published Consultation on changes to financial support for solar PV, setting out its intention to remove the current support mechanism for large-scale ground mounted solar energy projects.

The Renewables obligation (Ro) will close to new projects – and extensions – above 5 MW from 1 April 2015.

Neil Budd, a lawyer in the energy team at law firm SGH Martineau, said: “While the industry was braced for bad news, the proposal to remove Rocs entirely from projects above 5 MW has come as a shock.

“on a positive front, projects

of 5MW and below will remain eligible for Renewables obligation certificates and FiTs. So while the large projects may not now proceed, developers can, at least for the moment, still develop ground-mounted projects of a moderate size.

Decc has highlighted that projects can apply for contracts for differences (cfD) under the new regime being introduced this year.

“This is true, but the allocation mechanism for cfDs has not been finalised,” says Budd, “so it is difficult for project developers who were anticipating commissioning projects at 1.3 Rocs to develop projects with no idea of the likely revenue stream.”

With energy bills increasingly becoming a bottom-line cost for the UK’s major energy users, it is not surprising that we have seen energy enter the boardroom debate. A key topic among this debate is accuracy and transparency when it comes to budgeting for energy bills.

In today’s marketplace, energy bills contain so many unpredictable costs – from commodity prices that can change hourly, to transportation and network charges influenced by a whole host of elements. It’s these variables that can make a real impact on a business’ margins.

Taking into consideration the flexes in government policy, as well as commodity costs, we have worked behind the scenes to develop a tariff that will support our customers in the ever-changing market. We have designed a tariff to meet the needs of the board, provide

budget certainty for the duration of fixed contracts and deliver a promise not to reconcile against costs that are agreed as fixed.

For our electricity customers, this includes the Feed-in Tariff and Renewables Obligation, both having caused problems and volatile bills for businesses in the past. As a result, fixing these costs will enable companies to have a clear and stable monthly budget for energy.

The new tariff, launching on 7 July for our industrial and commercial business customers, is available across both power and gas.

whether you are partnered with us or another supplier, you can find out more about the Fixed: certainty tariff and discuss the new product with our dedicated team at [email protected]

Working with businesses for budget certaintyWith non-commodity elements now making up between 40-50% of electricity bills, and with many of these costs being associated with the evolving energy policy landscape, Darren Lennon, head of strategic sales at npower, explains how a new wave of ‘Fixed: Certainty’ tariffs will help UK businesses accurately budget for the years ahead

The UK government is making £20m available to support projects that deliver

lasting reductions in electricity demand, for example through the installation of a more efficient lighting system or a pump. The aim of this pilot will test whether EDR could participate in GB’s capacity market.

There will be a competitive auction process and participants will bid in an amount of electricity demand savings they can make and a price at which they are prepared to “sell” it. This will test the Capacity Market approach which takes bids from organisations to supply capacity. Successful bidders will receive funding in line with the level of their bid (£/kW) and the amount of savings proposed, spread across a payment at installation and on provision of evidence of that those savings have been delivered. This money will help subsidise the measure.

Bidding rules Projects will bid into an auction and commit to delivering a certain kW saving (not kWh, which is the measure for total energy used). Successful bids secure funding, that can then be used to support the installation of more efficient electrical equipment.

Projects will need to qualify and this will include submitting a project plan with estimated savings and a plan for measuring and verifying these. Applicants will bid a price, expressed in £/kW, for

which they are prepared to “sel” that electricity demand reduction (capacity) saving.

There will be a minimum bid size of 100kW in the auction. This may be achieved by a single project or through several projects, aggregated into a single application. There will be no limit on maximum bid size or on total subsidy awarded to any one participant (subject to the budget constraints of the funding available. Applications may include a mix of technologies and cover a number of sites or facilities.

Successful bidders will receive a grant payment – not a loan – from government for delivering EDR during the peak period, with efficiency savings split between a payment at installation and a second payment on providing evidence of the delivery of savings.

Behavioural measures will not be eligible for the auction timetabled here. However, organisations that deliver behavioural EDR measures are encouraged to contact [email protected] with a view to discussing how these might contribute to EDR delivery in future.

A maximum price will be set for the auction, to ensure value for money.

Payments If an applicant is successful then the contracts are for one year. Successful bidders will receive 50% of payment on confirmation of installation and a further payment of 50% on delivery of savings (ie, after 12 months’

operation, on receipt of evidence of the savings). Under-delivery will lead to payments being reduced.

Measuring and verifying savings (M&V)How to measure and report savings will build on the approach set out in international protocols (IPMVP) and include three broad approaches:• Deemed: savings are

pre-calculated for a list of technologies.

• Partial measurement: combination of metering and calculations or estimates of key variables.

• Full measurement approaches: metering before and after.

Who and what will be eligible?Projects will need to be based in Great Britain and deliver efficiency savings at least during times of winter peak electricity demand (4-8pm on weekdays, November-February). Projects which would not be eligible include: • Those that shift

electricity demand to other times of the day

• Measures benefitting from specified forms of government incentive (such as Climate Change Agreements, Salix loans)

• Savings made by switching to other energy sources (eg, onsite generation)

Applicants from all sectors – public, private and voluntary are eligible as long as they meet the criteria for

the pilot. Projects should be based in Great Britain (England, Scotland, Wales).

What projects and measures will not be eligible? • Those that shift

they receive is deducted from their claim for capital allowances4. For example, if a company invests £1,000 and receiving £100 from the EDR pilot, only £900 will qualify for capital allowances.

One of the key points to bear in mind is that the pilot will pay the difference that helps make a project viable for a business. So if reducing a five-year payback to three was acceptable, the EDR scheme would pay the difference between these two calculations. we&eTo register your interest in taking part in the pilot, or if you have questions, contact [email protected]

A steadfast Bearish start to the summer trading season, a result of the colossal quarter one 2014 sell-off, has kept many market participants at ease with regards to future hedges.

With complacency lingering over current pricing levels, due to the weak fundamentals governing energy prices, the market hasn’t seen such low trades in more than three years (going back to 2010) for most contracts, with some posting record lows since their inception.

Could traders be taking their eyes off the ball as a result of current sentiment?

Those who watch the wall… of worriesWhat we know and what we don’t know can be regarded as the foundation of the modern-day view of market uncertainty. Although we know the current state of the physical market with regards to storage, power margins, expected demand and even weather forecasts, government decisions and the actions of political dissidents have thus far reminded the energy market of the truly unforeseeable nature of geopolitical risk.

After the numerous market spikes caused by the annexation of Crimea, Ukraine’s election and most recently the sabotage attempt of a transit pipeline in Central Ukraine, uncertainty has persisted in the form of geopolitical added risk-premia despite the current accommodative and comfortably low trading price.

The bleeding, Casterly, rockDrawing blood from a stone has always been synonymous with a near impossible task, and the trading period of summer 2014 looks set to paint such a picture for those who missed out on this year’s biggest “short” opportunity.

As the cacophony of news flows leads to conflict between actual

market fundamentals and trading sentiment (geopolitical risk), prices at the back end of Summer 2014 (Qtr3 2014) look set to opt for an horizontal trading trajectory while still carrying the underlying risk of potential of prices spikes. On the back of energy market unfriendly news, similar to the recent breakdown in gas price negotiations between Kiev and Moscow, wholesale gas and power prices in the UK could quickly revisit the highs of mid-April or further north with the latest bout of disputes ending with Russia cutting off supplies to Ukraine.

A stark reminder Surrounded by the high degree of uncertainty emitted out of the Middle-East (Iraqi crisis) and Eastern Europe (Ukraine vs Russia), a “cautiously Bearish” outlook for the UK’s energy market reflects the plethora of upside risks still present in the form of geopolitical uncertainty.

LG Energy’s warning-plagued outlook aims to carefully guide the expectation of slightly lower prices in the second part of summer 2014 with a bold acknowledgement of the great upside risks, which can erupt at the drop of a hat (recent 10% weekend spikes). As a result, the need for a highly sophisticated approach to quantitatively measure end-users’ market exposure risk and the cost of the widespread complacency should be paramount, ahead of what may be another slow start to the winter of 2014.

EDF Energy is offering business the opportunity to fix their electricity

prices for up to five years. In what is claimed to be the

first of its kind, the company has created a £50m contract enabling South Staffordshire Water to fix the majority of its energy costs from day one.

Water companies’ income is controlled by a cycle that agrees their earnings and investment over a set period. This protects consumers, gives investors greater certainty and ensures best management of the water network. However, previous to its contract, South Staffordshire Water’s ability to fix its energy costs was limited by the availability of wholesale prices that matched ts five -year investment cycle.

The contract was signed in February 2014 for a supply starting in 2015 and runs for five years until 2020, when South Staffordshire Water’s next investment cycle finishes. The contract fixes the majority of the company’s electricity costs from the day of signature, giving South Staffordshire

Water greater certainty of the majority of its energy costs.

EDF Energy’s new approach takes South Staffordshire Water from relatively short-term purchasing to the more longer term; smoothing costs for consumers.

Keith Marshall for South Staffordshire Water said: “We believe that our customers can only benefit from this efficient approach. Electricity accounts for almost 20% of our annual costs, second only to salaries.

“We looked for an energy company that understood our purchasing needs and was willing to bring both its expertise and a competitive price to the table. This contract means South Staffordshire Water can better focus attention on energy reduction and carbon management rather than trying to beat the wholesale market.

“The team at EDF Energy worked effectively in partnership with our legal and energy teams to design this contract. They fully understood the challenges of forecasting for a five-year AMP cycle and built a

product for us that works.”Sid Cox, director of the

business division at EDF Energy, said: “We know that businesses are looking for ways to control costs and reduce risk. Businesses wanting to get long-term price certainty should follow South Staffordshire Water’s lead.

“Partnership with our sister company EDF Trading made this unique purchasing approach possible and I believe this industry first would also benefit other businesses that want longer-term price certainty. We are even able to offer prices out as far as 2024 from today.”

Water companies’ income

is controlled and fixed over a five-year period through a consultation process with Ofwat known as the Asset Management Planning (AMP) cycle. This process agrees their income and investment over the period, protects consumers, gives investors greater certainty and ensures best management of the water network.

Energy costs are a significant part of water companies’ costs and their ability to fix these is limited by the availability of wholesale prices that match the AMP cycle. Generally, wholesale electricity prices are only quoted three years into the future. we&e

Vayu will become the first Irish energy supplier to target the UK business gas

sector. It has grown steadily since 2003, when it became the first independent supplier to be awarded a gas shipping and supply license in Ireland.

The company now supplies 22% of Ireland’s largest natural gas business users and 15% of the mid-sized gas user segment. Gas customers include companies such as Tesco, IBM, Debenhams and DHL.

Vayu commercial director Liam Faulkner says the company is focused on becoming a leading provider of gas and energy procurement solutions to businesses across the UK, giving customers a competitive alternative to other suppliers in the sector.

“We believe there remains a large untapped opportunity to deliver new services into the UK market. Vayu will be investing heavily in winning customers by changing the way UK businesses view their energy-related decisions and empowering customers to become more active in the

area of energy procurement and demand management.”

“We have established a business model that has worked exceptionally well in Ireland, creating flexibility for gas users that wasn’t there previously. Our model is highly transferable – similar to the approach used by telecoms – which means we can follow our existing customers into the UK while also pursuing new business wins in this market.”

Heading up the UK business is head of energy services Vayu UK Simon Firth, who is to grow Vayu’s customer base in the UK. He brings a wealth of experience and passion for delivering exceptional customer service, having spent 20 years in the energy industry working in a variety of segmented sales and service roles for Yorkshire Electricity Group, Npower and Bergen Energi.

Commenting, Mr Firth states: “This is a very exciting time for Vayu as we enter into the UK market and I believe we have outstanding solutions to offer. In addition to gas supply, our Active Energy Management service monitors

consumption in real time, reporting back deviations from normal energy usage. At Vayu UK, we use energy management, monitoring and technology to improve our customers’ energy performance, reducing cost, consumption and carbon.

“While we are industry experts in the registration and invoicing of gas supplies we realise that the timing of wholesale commodity purchasing is one of the central factors in achieving or beating financial budgets, and so Vayu UK adds significant value to businesses by offering risk management

services. These services help support clients with their understanding of the consumption and commercial risks faced with purchasing energy in a volatile market. We work with customers to develop robust purchasing strategies, with a documented risk management approach.

“This end-to-end solution of Active Energy Management, pro-active risk management, integrated with supply, provides the best long-term value package for end users and allows us to offer a compelling alternative to gas users in the UK.”

Energy procurement is becoming increasingly more complex – as well as a raft of new

suppliers bringing more choice, the entire market is being overhauled under the coalition government’s Electricity Market Reform. Getting the right blend of price, sustainability and service in a moving market is a challenge.

Prices forecast to be more volatilePrice is still the biggest issue for many buyers and the long-term rising trend means energy is firmly established as a key risk for any business. And it is not just the cost of the energy itself which has risen but other charges, such as those to pay towards network upgrades and renewable subsidies, have also increased dramatically.

Market changes, political instability and the growth of intermittent renewable generation give rise to a new risk in the shape of greater volatility.

Rising prices and greater volatility means energy buyers are increasingly looking for

contracts that can help them better manage risk and take advantage of any opportunities to secure lower prices.

Flexible contracts enable businesses to actively manage their purchasing strategy to benefit from favourable market prices. Such contracts used to be restricted to the largest energy buyers but recent innovation from SmartestEnergy means smaller businesses can also take advantage of a flexible purchasing strategy.

The growth of other charges also prompted us to develop EnviroPass, a unique product that passes through environmental charges at published rates, guaranteeing that companies never pay more than needed for their energy.

Sustainability agenda on the riseAs well as looking to better manage costs, business energy customers are increasingly sourcing more sustainably. Many of the UK’s leading companies have switched to 100% renewable energy as part of wider corporate

social responsibility ambitions – see the case studies on Marks & Spencer and John Lewis Partnership (below).

Looking ahead, we expect more and more major business energy users to want to demonstrate to customers and stakeholders exactly where there electricity has come from.

Service still a differentiator for suppliersImprovements in service

across the industry have been led by new entrants such as SmartestEnergy. We have achieved the highest levels of customer satisfaction* for four years in a row - proving that price, sustainability and service can all be delivered in a single package.

We try to always put

customers at the heart of our business, providing services to help them manage their energy usage in the most effective way. Accurate, up-to-the-minute information about energy consumption and cost is important to manage costs, reduce waste and improve sustainability.

A personal relationship between buyers and suppliers is also important. In an increasingly complex energy world, being able to pick up

the phone to chat through the implications of the latest policy announcement or market development is something that all energy buyers should expect from their supplier.*Datamonitor B2B Energy Buyer Survey 2010, 2011, 2012 and 2013

Case studies: retailers lead the way on sustainabilityMarks & Spencer has worked with SmartestEnergy to develop the first agreement of its kind under which electricity equivalent to the retailer’s 65 Scottish stores is sourced from independent generators north of the border. These generators include community projects, where funds generated are being used to help provide amenities for residents in remote areas.

The John Lewis Partnership also recently signed a major energy supply deal with SmartestEnergy, which will provide a major boost to renewable generation projects owned by communities, farmers and small businesses across the UK. The agreement will see more than 380 Waitrose and John Lewis sites supplied with 100% renewable electricity from SmartestEnergy’s portfolio of hundreds of independent generation projects.

“We have achieved the highest levels of customer satisfaction for four years in a row – proving that price,

sustainability and service can all be delivered in a single package

Energy procurement is becoming increasingly more complex – as well as a raft of new

suppliers bringing more choice, the entire market is being overhauled under the coalition government’s Electricity Market Reform. Getting the right blend of price, sustainability and service in a moving market is a challenge.

Prices forecast to be more volatilePrice is still the biggest issue for many buyers and the long-term rising trend means energy is firmly established as a key risk for any business. And it is not just the cost of the energy itself which has risen but other charges, such as those to pay towards network upgrades and renewable subsidies, have also increased dramatically.

Market changes, political instability and the growth of intermittent renewable generation give rise to a new risk in the shape of greater volatility.

Rising prices and greater volatility means energy buyers are increasingly looking for

contracts that can help them better manage risk and take advantage of any opportunities to secure lower prices.

Flexible contracts enable businesses to actively manage their purchasing strategy to benefit from favourable market prices. Such contracts used to be restricted to the largest energy buyers but recent innovation from SmartestEnergy means smaller businesses can also take advantage of a flexible purchasing strategy.

The growth of other charges also prompted us to develop EnviroPass, a unique product that passes through environmental charges at published rates, guaranteeing that companies never pay more than needed for their energy.

Sustainability agenda on the riseAs well as looking to better manage costs, business energy customers are increasingly sourcing more sustainably. Many of the UK’s leading companies have switched to 100% renewable energy as part of wider corporate

social responsibility ambitions – see the case studies on Marks & Spencer and John Lewis Partnership (below).

Looking ahead, we expect more and more major business energy users to want to demonstrate to customers and stakeholders exactly where there electricity has come from.

Service still a differentiator for suppliersImprovements in service

across the industry have been led by new entrants such as SmartestEnergy. We have achieved the highest levels of customer satisfaction* for four years in a row - proving that price, sustainability and service can all be delivered in a single package.

We try to always put

customers at the heart of our business, providing services to help them manage their energy usage in the most effective way. Accurate, up-to-the-minute information about energy consumption and cost is important to manage costs, reduce waste and improve sustainability.

A personal relationship between buyers and suppliers is also important. In an increasingly complex energy world, being able to pick up

the phone to chat through the implications of the latest policy announcement or market development is something that all energy buyers should expect from their supplier.*Datamonitor B2B Energy Buyer Survey 2010, 2011, 2012 and 2013

In a letter to large suppliers, Ofgem outlined that “failure to engage with consumers on this issue further risks

undermining public confidence in the energy market if wholesale costs continue to fall”.

It is a fair assumption that the recent drop in wholesale gas and electricity prices should be passed on to consumers – we know commodity cost accounts for 45% of a domestic bill and similar for businesses, so surely consumers must feel the benefit of a price fall, and not just encounter the pain of an increase?

The decision whether or not to reduce customer prices should be based on a transparent set of facts and calculated risks, which suppliers, consumers and regulators alike can subscribe to, rather than the current situation where everyone is left wondering whether suppliers are playing fair.

However, the reality is far more complex and the issue runs far deeper within the suppliers themselves than a simple decision whether to pass on a movement in the wholesale cost of energy.

While it is true that a prolonged reduction in wholesale costs means overall supplier costs are reduced, the reality of suppliers’ data management means it is far harder for most to see actual customer-level costs and the margin contributed directly at this level – making it virtually impossible to calculate the risk of a price change and determine which customers are currently profitable, and which are not.

are forced to determine price changes by reviewing the profitability of their retail business as a whole at hugely amalgamated levels, because they don’t have a detailed customer-level view on costs. For example, not being able to reconcile the impact of long- and short-term energy purchasing decisions against customers’ actual consumption – has led to a poor (or non-existent) understanding of customer-level margin and overall profitability.

This absence of detailed

account-level data often forces suppliers to adopt a risky “one-size-fits-all approach” across their portfolios. An inability to view energy purchased against energy sold at a customer level allows discrepancies to go undetected and drives inaccurate and inconsistent views of customer costs.

It is this inability to understand value at a customer level that makes the decision to pass through a price cut far more difficult as suppliers simply do not know which customers are value generating – meaning the very real risk of a large proportion of customers becoming loss making as a result of pricing decisions based on inaccurate assumptions.

Actual customer insight just doesn’t exist in a supplier world which came from a geographically regionalised approach, and since privatisation the

supporting data management infrastructure just hasn’t caught up. The root cause is the continued use of out of date, inadequate data management processes, which is preventing energy suppliers from using the mass of data available to them.

The data issue extends beyond pricing: the whole energy industry is reliant upon a large number of complex messages being passed between the various parties that are involved in getting energy across the network and to the homes and businesses that use it. Individual data flows detail every event against a meter, from changes of supplier to the recording of actual consumption data. These complex messages make up the information required by energy suppliers to manage a customer’s energy supply, so they know what has been used and therefore, in turn, how much their bill should be.

Precise customer billing, accurate forecasting and therefore reduced settlement risk all depend on accurate data, upon which decisions can be based.

If suppliers want to earn consumer trust and provide accurate billing, deliver better customer experience and fair and transparent pricing, they need to accept that current practices will not deliver this – but it is in their gift to change it.

the principle of new technologies improving on or complementing old ones is well established, and is clearly illustrated in the evolution of boiler controls

New technologies solve problems, increase efficiency and often give us greater control over day-to-day processes. And, in the main, each technological advance improves on the last to deliver better performance. This is certainly the case with retrofitted boiler controls, which have advanced considerably during the past 40 years.

1970sIn the 1970s, for example, “time delay” devices were introduced to try to prevent boiler dry cycling, where the boiler fires to replace heat lost through standing losses rather than in response to a genuine requirement for heat in the building or process. Unfortunately, these prevent the boiler from firing on the basis of a fixed time delay, rather than by temperature. Consequently, firing might be delayed even when there was a genuine need for heat in the building, resulting in suppressed temperature. Controls using a time-delay approach are still on the market and suffer from the same limitations.

1980sIn the 1980s, the introduction of microprocessors enabled building management systems (BMS) and building optimisation, with a positive effect on the efficiency and control of heating in buildings. These technologies have continued to evolve and, when properly commissioned and maintained, remain as the vanguard of boiler control in many commercial applications.

1990sNevertheless, most BMS are not configured to detect or control the ongoing problem of boiler dry cycling directly, so the 1990s saw the introduction of “load compensation” or “burner management” controls. Many of these result in lowering the boiler’s design operating temperature by 2-5°C, using a single temperature sensor to monitor the boiler’s return temperature. Without monitoring both flow and return

water temperatures these devices cannot differentiate between boiler dry cycling and firing to meet a genuine demand for heat. Consequently the boilers cannot respond to a genuine demand and comfort temperatures can be compromised. Some of these devices also use a timer to record how long the burner has or hasn’t been firing – presenting this as actual energy saving – which isn’t the case. They can also cause issues with weather compensation and other control strategies and are not compatible with emerging control strategies.

2000sThese issues led to a new approach to address dry cycling in the early 2000s – Intelligent Boiler Load Optimisation – in the form of Sabien’s patented M2G. M2G is unique in that it does not lower set points or the system’s average temperature. Instead, it uses real time measurement and analysis of both flow and return water temperatures to identify the boiler load specifically and whether the boiler is dry cycling or whether there is a genuine heating demand. Furthermore, it is compatible with all current and future BMS. Indeed, the majority of the 8,000 M2Gs in use across Europe, the US and Asia are installed alongside modern BMSs. Analysis demonstrates average energy savings of 12% with payback approximately 18 months.

the futureThere can be no doubt that buildings and their services will be expected to become ever more efficient in the future, in line with tighter energy consumption and emissions targets. Using the latest boiler controls, that also incorporate an element of future-proofing, is clearly the logical way to achieve greater energy efficiency.

Keeping up with the evolution of boiler controlsEnergy sector faces rising

pressures from climate change

the energy sector is facing increasing pressures from climate change. All

segments of the industry will be affected by the changing global climate and the policy responses to it, according to a briefi ng published jointly by the World Energy Council (WEC), the University of Cambridge Institute for Sustainability Leadership (CISL), the Cambridge Judge Business School, and the European Climate Foundation.

The briefi ng brings into focus the energy-related fi ndings of the Intergovernmental Panel on Climate Change (IPCC) Fifth Assessment Report (AR5) for policymakers and business leaders in the energy sector. It identifi es the need to incorporate climate change mitigation and adaptation measures into energy policymaking, infrastructure planning, and investment decisions.

The briefi ng, Climate Change: implications for the energy sector, reveals energy demand is increasing globally, causing an increase in greenhouse gas (GHG) emissions from the energy sector. The trend is set to continue, driven primarily by economic growth and rising population.

Climate change presents increasing challenges for energy production and transmission as a result of temperature increases, extreme weather events, and changing precipitation patterns.

Signifi cant cuts in GHG emissions from energy can be achieved through a variety of measures, including cutting emissions from fossil fuel extraction and conversion, switching to lower-carbon fuels, improving energy effi ciency, increasing use of renewables and nuclear, introduction of carbon capture and storage (CCS), and reducing fi nal energy demand.

Strong global political action on climate change would have major implications for the energy sector. Incentivising investment in low-carbon technologies will be a key challenge for governments and regulators to achieve carbon reduction targets.

Philippe Joubert, advisory board member for the Cambridge Institute for Sustainability Leadership, executive chair of the WEC’s Global Electricity Initiative, and former president of Alstom Power, comments: “The latest climate science is clear about the reality and impacts of climate change. This summary report helps business to understand the scale and urgency of the issues involved for the energy sector and should be seen as a call to action for the leaders of a sector which is responsible for over a third of CO2 emissions. Leading businesses in this sector increasingly realise that business as usual is no longer possible nor acceptable.” we&eThe report is available at worldenergy.org/news and is accompanied by an infographic which summarises the key fi ndings


Rising costs, potential shortages. The quest for decarbonisation. Energy is a potential minefield for businesses – and never before has it had such a key strategic profile. Managers know they need to actively manage energy, from procurement to efficiency – but it can be difficult to know what measures need to be put in place, and what solutions are available. Happily, good energy suppliers can offer a great deal of support and smart managers are increasingly building this into their supplier selection processes, writes Mike Hogg, managing director, DONG Energy Sales

How can your energy supplier help you? By turning data into bottom line impact

Gas & ElEctricity

One of the most impactful measures a business can take is to actively

monitor consumption data and charges. By gaining a detailed understanding of when and how energy is used, for what processes and at what cost, operational decisions can be made to optimise resources. For example, by shifting the timing of industrial processes as far as is practicable so as to avoid peak times when energy prices are higher. Data can also help to identify anomalies, errors and opportunities for greater focus: ensuring equipment, lights and heating are switched off when not in use, for example.

impact through supply partnerships Through the long-term partnerships DONG Energy enjoys with customers, it’s clear that organisations that continually strive for improvement will see a significant and sustained impact on both the carbon footprint and the bottom line. Information (data and intelligence) is key to that – whether it is market data, updates on the regulatory environment or detailed consumption and cost breakdowns. By tracking

energy consumption per unit of output, businesses can accurately predict energy usage, which enables suppliers to minimise the industry charges to be paid – resulting in lower costs. The same data can be used to identify inefficient practices, which is particularly crucial in energy-intensive industries, where energy can easily account for around 25% or more of the total cost base.

The opportunities multiply as technological innovation (such as automated meter reading) facilitate unprecedented degrees of transparency. Basically, the more granular the data, the more dramatic the impact can be. The seemingly simple task of examining each unit of consumption can unlock valuable insights into wastage and inefficiencies – and how to minimise them. Obviously, advanced meter technology is making this data more accessible but it is also something that energy suppliers can and should help with – data solutions are a key part of the service requirement and customers should make sure they get what they need from their supplier.

Getting on the boardroom agendaDay-to-day energy

management is vital but, particularly if energy is a significant portion of the total costs for the business, a long-term energy strategy is needed to achieve maximum efficiencies. This means understanding the role energy plays in the business and ensuring that the resources and processes are in place to manage it.

It means selecting a supplier that takes the time to understand your business and delivers a product that is the right fit. It means helping staff to understand what behaviours are

valued and incentivising them accordingly. It means having a clear and shared vision of the company’s short- and long-term energy reduction goals. It means staying abreast with the regulatory and compliance environment and making the most of opportunities.

Here again, this is an area where suppliers should provide advice and solutions – ideally as part of a long-term partnership approach which can encompass data-based solutions, third-party arrangements, renewables investment and CSR support.

case study: GlatfelterUS paper manufacturer Glatfelter is headquartered in Pennsylvania with a global reach including facilities in Germany, France, UK and the Philippines. The company has seen exceptional growth in recent decades and now employs about 4,200 staff. With a dual focus on environment and product diversity, energy is of strategic importance. Senior energy manager Jamie Lavis is responsible for procuring and managing energy supply, including for the company’s two UK locations.

He says: “As a manufacturing company, it is key that we can quickly access billing and consumption data in order to spot anomalies and make operational decisions The bills from DONG Energy are succinct and transparent, with all charges clearly identified. This is really important to me as I need to closely monitor that information in detail as, in addition to being an important financial accounting tool, it underpins our energy

“In addition, we receive comprehensive pricing and market data to help manage, monitor and measure the market and our position. This information is very valuable as it informs not only immediate hedging decisions but our decision-making going forward. On top of that, we also receive monthly information about the regulatory environment, market fundamentals, network code updates and revisions to distribution charges – those things aren’t always publicised a great deal and it’s not always easy to forecast.

“necessity, not nicety” for all organisations, it says.

Heavy-energy industry sectors including transport, food producers and manufacturers, public sector organisations such as hospitals, schools and local authority buildings, energy companies and construction firms have the most to gain from overhauling their energy management procedures.

Failing to act could expose businesses to significant

financial pressures and market uncertainties, as well as reputational risks, in the long term.

A spokesman for the international testing, inspection and certification body said curbing inefficient usage could save the UK industry sector billions of pounds in wasted energy.

It also has the very real potential of reducing industry’s global carbon footprint, which last year amounted to 75 million tonnes in the UK alone.

Tom Johnston, BM TRADA’s chief operating officer of Central Certification Services, said companies need to continue rising to the challenge of energy management.

Speaking at the launch of BM TRADA’s expansion into UKAS-accredited ISO 50001:2011 Energy Management Certification, following a successful pilot scheme, Mr Johnston said: “The cost of energy is rising rapidly, fuelled in part by growing concern over energy security, and it is the business and public sectors that are feeling the financial impact the most.

“At the same time, energy efficiency is now firmly on government agendas in a bid to tackle carbon emissions and wastage in the industrial sector is being met with increasingly heavy penalties.

realise, running into millions of pounds, but are also leaving businesses and organisations wide open to financial and reputational risks which they can ill afford to deal with.”

The comments come just months after Sam Laidlaw, the chief executive of British multinational utility company Centrica, warned that the UK would be reliant on natural gas imports of 70% by 2020.

Governments and NGOs around the world are putting increasing pressure on the private and public sector to improve their energy efficiency and reduce their carbon footprint.

In 2013, the UK produced an estimated 463 million tonnes of carbon dioxide – the primary greenhouse gas and a major contributor to global warming – of which 16% was generated by the business sector.

Under the Kyoto Protocol, the UK government has a legally binding target to reduce emissions and since 2001 has operated a climate change levy to provide industry with an incentive to increase energy efficiency and reduce carbon emissions.

It has also introduced mandatory carbon footprint reporting for UK listed companies, with the potential for the scheme to be extended to cover all large corporations from 2016.

UK carbon dioxide emissions have decreased by about 21% from 1990 figures, but a study by the Carbon Trust has revealed that large UK businesses are still spending over £1.6bn on wasted energy each year.

And without greater corporate commitment to energy management, Britain risks missing legally binding targets to reduce carbon dioxide emissions by 80% by 2050.

Mr Johnston says that carbon taxes, wastage and increasing energy

costs – expected to rise by up to 25% for industrial users by 2020 according to government adviser the Climate Change Committee – make the case for ISO 50001 Energy Management Certification clear cut.

He added: “When you factor in carbon levies, rising energy costs and wastage, which the Confederation of British Industry estimates can account for between 10 and 20% of energy costs, the potential savings to be gained from developing a comprehensive energy management strategy are huge.

“In addition to bringing significant reductions in operational costs and protecting against energy price spikes, becoming certified to the ISO 50001 standard also ensures that a business is meeting the latest regulatory requirements, which sends out all the right messages to clients and the public about their commitment to energy reduction, best practice and sustainability.

“The new standard is easy to implement, is designed to cause minimal disruption and will help businesses to implement the processes they need to understand their baseline energy usage and establish a best-practice energy policy throughout the business, including plans, targets and KPIs for reducing energy consumption.”

ISO 50001:2011 is the international standard for energy management, providing an effective framework for improving energy performance, efficiency and consumption, and integrating this into management practices.

The standard integrates with, and complements, existing management systems such as ISO 9001 Quality Management & ISO 14001 Environmental Management. we&e

Martin Hockaday, environment and energy sector manager at NQA, reviews the Plan, Do, Check, Act

cycle of ISO 50001 and how it improves energy management

In the last issue we looked at the first step of the Plan, Do, Check, Act model and focused on the energy planning process defined in ISO 50001. This article gives an overview of the second step, Do, or as ISO 50001 calls it, implementation and operation of an energy management system (EnMS). It is worth remembering that ISO 50001 is applicable to any type and size of organisations, irrespective of industry, geography or culture.

Implementation and operationThis section of the standard has seven main requirements that turn the outputs of the energy planning process into action that is structured, communicated and where relevant documented. It is worth noting that documentation should be treated with pragmatism – where the standard requires documentation then it must be followed to achieve compliance, but it is unnecessary to create additional records unless they add value to your EnMS.

Competence, training and awarenessThis requirement applies direct employees and subcontractors who impact on significant energy uses, which are identified in the energy plan. Flexibility of training methods is given, but should be appropriate to the role, responsibilities, education, skills and experience of each individual. Whatever method, appropriate records are required by the standard.

Communication Communication is critical to the effectiveness of the EnMS, internal and external communication is required. It is expected that internal communication is a two-way process that considers suggestions for improvement of the EnMS. This is a key engagement activity.

DocumentationISO 50001 does not intend bureaucracy and provides good

flexibility for documenting the EnMS. This could be paper or electronic records, but also signage, diagrams, flow charts and dashboards that communicate the objectives, actions and achievements of the EnMS.

operational controlResponding to this requirement will vary significantly from organisation to organisation. The fundamental aim is to ensure that energy policy, targets and action plans are implemented within operational and maintenance activities.

DesignIdeally energy efficiency should be designed into the EnMS to maximise its performance from the point of implementation. This requirement states that the results of design activities are recorded.

Procurement of energy services, products, equipment and energyProcurement has a significant impact cost, resource and efficiency. It is specifically addressed and procurement processes must be established, documented, evaluated and communicated. Life cycle analysis should be considered in evaluation.

SummaryThis brief overview of implantation and operation should give a flavour for the nature of the requirements of ISO 50001 and demonstrate its flexibility. The key conclusion is that ISO 50001 provides a scalable framework that can be implemented in the most appropriate way to your organisation to provide continual improvement of energy management.

In the next issue of we&e, we’ll look at the Check stage of the process. This essential step ensures that the EnMS is effective and continually improved. If you can’t wait until then you or if you want more information about implementing ISO 50001 visit www.nqa.com/enms or contact [email protected]

A tool for improvement?Energy Managers Association CEO Lord Redesdale asks if the new ESOS legislation will be another report that gathers dust on a shelf or if it will gain traction, achieve savings and raise the profile of energy further at board level

the government is placing Energy Savings Opportunity Scheme (ESOS) regulation in

front of parliament on 26 June. As you are reading this after 26 June and your organisation meets the criteria for compliance – having more than 250 employees or a turnover of €50m plus – you need to start thinking about how ESOS will affect your organisation.

The purpose of ESOS is to identify an organisation’s potential energy efficiencies though an audit of its estate and processes.

Organisations have to determine whether or not they are in scope by December 2014 and have completed the audit by December 2015. The process will then be repeated every four years.

If you are a UKIP supporter ESOS is a horrendous imposition from the European Union on good old British energy inefficiency. If you are an energy professional, whether you vote UKIP or not, this could be a powerful and convincing professional tool.

On completion, potential energy efficiency measures need to get signed off by a company director. Energy efficiency, a subject that has been ignored by boards for far too long, will be placed in front of them by law.

Legislators at all levels are trying to push companies to becoming more energy efficient. To hit the target set by the EU for 2020, €60bn a year needs to be invested across the member states. The amount that is being invested at present comes nowhere near

meeting that target. The reality is that the no body can afford to subsidise this level of energy efficiency investment and therefore money will have to come from companies investing in their own buildings and machinery. This will become more pressing in large parts of Europe because energy security and supply issues will lead to a rise in the price of energy.

In Britain, commercial energy prices are projected to rise sharply as they have already done over the past decade. As a result, in a next few years boards are going to take energy efficiency much more seriously and this is why the ESOS is such a fantastic tool. Organisations will have a long list of useful energy efficiency measures to place in front of their board.

This all sounds great, you say, but how would the process work? Organisations are required to appoint a lead assessor to oversee the process. The competence of the lead assessor is determined in relation to the Publicly Available Standard PAS 51215.

The main issue that energy or facilities managers will have to take on board is that the whole process could be outsourced, but more importantly, could easily be kept in house. The lead assessor will have to show an understanding of the process. If there are areas of the audit that they believe they are not qualified to undertake then they can outsource that particular area to third parties.

The EMA will be launching a lead assessor course for those looking to become more rounded assessors.

If possible, in-house teams should control the process. There is a little point in commissioning the best audit in the world if it is not “owned” by those who have to fight for the investment from the board. Too often in the past energy audits have been undertaken and while the glossy pack is produced, it is often being ignored and left unread instead of being acted on. ESOS being owned by energy and facilities managers with lead assessor training is far more likely to appeal to gain traction.

The EMA will be holding free seminar sessions discussing the whole process at EMEX in November. we&eLord Redesdale established the Energy Managers Association in February 2012 and it now represents energy managers from companies with a collective energy spend of about £3bn

SMART.Dash from t-mac Technologies is a new, responsive web application that

claims to be the UK’s first energy saving dashboard with a dedicated twitter feed. It is designed to enhance energy-saving opportunities and encourage active energy awareness from employees.

SMART.DASH connects with the t-mac cloud displaying a building’s data, collected from areas such as meters, sub-meters, machinery equipment and renewables. It provides real-time energy insights with dynamic, intuitive and insightful views. The use of the latest web technology ensures that it is completely responsive and viewable on all devices from tablets to desktops and smart TVs to mobile phones.

A benefit of SMART.DASH is that it taps into an organisation’s own twitter account, allowing businesses to reach out through social media and educate occupants on energy saving at work while showcasing to customers.

It also features a league

table with benchmarking and KPI facilities, allowing comparisons to be drawn year-on-year or site-to-site to create a well-rounded energy view.

Lisa Gingell, director, t-mac Technologies, said: “Our research and the market’s appetite has shown us that what business big and small want is a completely customisable, and fully interactive energy management dashboard that will help them display their energy-saving efforts. SMART.DASH goes some way in making this a reality.

“We believe SMART.DASH is the future for web application technology in the energy sector, because it harnesses the social media enthusiasm of all users and also works by empowering occupants with tips and advice. Ultimately, smarter occupants create greener buildings in the long term.”

SMART.DASH is suited to all markets and industries and can be incorporated into the current energy saving effort of hundreds of businesses, from large office developments

to small factories and retail units it can also be applied to the education sector and utilised within schools.

While auditing is a regular feature of life for all businesses, the

extension of this approach to all aspects of the commercial world – including “non-core” activities such as energy and environmental management – has been a long time coming.

Of course, for many organisations, the measurement and management of energy is a long-standing feature of their operational activities. Yet, the lack of take-up in some of the largest businesses has prompted the European Union to take action in this area. The Energy Savings Opportunity Scheme (ESOS) is now reaching its final stage and will be published shortly if it has not already appeared by the time you read this article.

ESOS is the UK’s “transposition” of Article 8 of the EU’s Energy Efficiency Directive. It is a mandatory energy assessment and “energy saving identification” scheme for large organisations. Non-SMEs (only the private sector is involved, although some universities could find themselves included as well) will have to carry out regular audits of their energy usage.

It is astonishing that, in an era of high energy prices and global competitive markets, energy efficiency is not seen as an essential element in any operational manual.

Making the most of an opportunityThe official guidance for the Energy Savings Opportunity Scheme has just been published by DECC, Richard Hipkiss asks if this will be a real game-changer

Yet estimates of achievable, cost-effective savings remain stubbornly high both here in the UK and more widely across Europe. The European Commission and the UK government routinely quote figures of 20%, while ESTA’s own evidence from members suggests the savings can actually be much greater.

These audits have to be complete under Phase 1 of the scheme by the end of 2015 and they must be based on a full 12 months’ figures of at least 90% of consumption, including the energy used in buildings, for transport and in industrial processes.

That does not leave much time for business to get organised: the deadline means that the accounting period must start sometime this year and, at the time of writing, we are already in June.

These energy audits must be undertaken, or approved, by lead auditors. Organisations

representing auditors will be approved by

the Environment Agency as the scheme administrator. However, it is likely that EA will not be

in a position to publish its

list of approved bodies much before

the end of the year. If businesses want to get

started early, where can they go? Well, one place would be the Register of Professional Energy Consultants. RPEC is operated jointly by ESTA and the Energy Institute. As an independently assessed

register of experienced, qualified energy consultants, RPEC will be applying for inclusion on the EA’s listing (more details from www.esta.org.uk/rpec).

It is important to note that only qualified professionals will be able to carry out these audits. Clearly, if the audit is to be accurate and is to identify cost-effective savings, then it is essential to use people with the right experience.

Many businesses are already

in some form of auditing scheme, such as the EU Emissions Trading Scheme or the CRC Energy Efficiency Scheme. The monitoring and auditing procedures associated with these will be accepted for compliance with ESOS but it is unlikely that any of these schemes will cover the full range of activities covered by this latest scheme (such as transport energy for example). So it is likely that some additional auditing, as well as collating of data streams, will be necessary.

The government estimates that the scheme could lead to £1.7bn net benefit to the UK “with the majority of these being directly felt by businesses as a result of energy savings”. That does, however, rely upon organisations taking heed of the findings in the audits and taking action.

Earlier schemes – such as those run by the Carbon Trust – have not been especially encouraging, with implementation rates as low as 20%. Under ESOS, firms will have to pay for the audits so there may well be an incentive to recover the costs.

However, there may well need to be further incentives (either carrots or sticks) if the benefits to the UK are to be anywhere near the government’s figure. we&e

Insulating paints: mere greenwash?Vilnis Vesma tackles the issue of insulating paints and whether they can actually retain heat within a buildingReducing heat loss

through some types of building structure – solid walls and

single-skin roofs, for example – requires insulation applied to the surface, which can be disruptive and awkward and may encroach on the interior space. So one can see the attraction of insulating paint or paint additives. Is there any scientific basis to the claims made for them?

The effectiveness of thermal insulation depends on its thickness and its thermal conductivity, λ, which in SI units is stated as W/mK*. Typical conductivities are: • Dry brick 0.8-1.2 W/mK• Expanded polystyrene

0.035-0.055 W/mK• New polyurethane gas-filled

board 0.017-0.020 W/mK

So because expanded polystyrene is roughly twice as conductive as polyurethane board, one would need double the thickness of it to achieve the same insulating effect.

Each layer of a building structure has a thermal resistance R proportional to its thickness d and inversely proportional to its thermal conductivity, ie R = d/λ. The thermal resistance of a complete structural element is the sum of the thermal resistances of each of its constituent layers. For example a cavity wall (see Table 1).

Note that the surfaces and cavity have some thermal resistance of their own. The U-value of the wall – the way thermal performance is usually expressed – is the reciprocal of total thermal resistance. In this case U = 1/0.664 ≈ 1.51 W/m2K

If, in the example in table 2, we were to fill the 50mm cavity with fibrous insulation (λ =0.04), we increase the thermal resistance of that layer (shown in bold). This brings the overall

resistance up to 1.734 m2K/W giving a U-value of 0.58 W/m2K.

To evaluate the effect of an insulating paint we will have to make some assumptions, firstly about its thermal conductivity. I will base my estimates on a common type of additive called “ceramic microspheres”, which supposedly contain a vacuum.

Although, as the advertisers are quick to remind us, heat cannot travel through a vacuum, it can of course travel through the walls of the spheres (which will have high conductivity and represent a substantial fraction of their cross-section) and through the pigment and binder around them. So let us say the paint has

λ=0.04 W/mK, which is similar to cork or cellular rubber.

What about the thickness? An advert for one typical paint additive states the product, whose packaging has a volume of 1.3 litres, is added to 2.5 litres of paint to give a coverage of 18 sq m. This works out as an applied thickness before drying of 0.21 mm. Let’s be generous and say that the finished thickness is 0.20 mm.

Now in table 3 see what happens when, instead of cavity filling, we paint our unfilled cavity wall from the previous example.

The new U-value is 1/0.669 ≈ 1.49 W/m2K and the improvement is less than 1%. Hence claims that such treatments can save “up to 25%” are clearly misleading

Some vendors claim that the ceramic microspheres reflect heat. However, any such claim must also be spurious because thermal reflection depends entirely on the paint’s surface finish. Unless the surface itself has very low emissivity – essentially, looking like a mirror to infra-red radiation – it will absorb heat regardless of any additives within the paint itself. we&eThis is one of a series of occasional papers discussing exaggerated or bogus claims for energy saving.

This works out as an applied thickness before drying of 0.21 mm. Let’s be generous and say that the finished thickness is 0.20 mm.

Now in table 3 see what happens when, instead of cavity filling, we paint our unfilled cavity wall from the previous example.

The new U-value is 1/0.669 ≈ 1.49 W/m2K and the improvement is less than 1%. Hence claims that such treatments can save “up to 25%” are clearly misleading

Some vendors claim that the ceramic microspheres reflect heat. However, any such claim must also be spurious because thermal reflection depends entirely on the paint’s surface finish. Unless the surface itself has very low emissivity – essentially, looking like a mirror to infra-red radiation – it will absorb heat regardless of any additives within the paint itself. we&eThis is one of a series of occasional papers discussing exaggerated or bogus claims for energy saving.

The RAF Museum in Cosford, Shropshire, which attracts 300,000 visitors

every year, houses 70 aircraft in three hangars. Built in the 1930s, the hangars use gas-fired radiant tube heating – the largest of which costs £50,000 a year to heat.

Energy efficiency business Vickers Energy will install its energy management system to optimise the heating in two of the hangars – with a projected reduction in CO2 of 103 tonnes per year and a further saving of at least £9,500 a year for the museum.

The installation follows a successful project last year where Vickers delivered a system to regulate the heating in the museum’s largest hangar.

The system has already allowed the museum to reduce gas consumption by 28% and CO2 emissions by 96 tonnes per year for the 5,000 sq ft hangar – leading to a saving of £14,000.

The RAF Museum Cosford is one of two RAF museums nationally and features the world’s oldest Spitfire and a Lincoln Bomber among its 70 aircraft.

Condensing boilers with energy features as standard

Baxi Commercial has launched its Paramount three range of high-efficiency condensing

boilers. There are six different outputs: 30kW, 40kW, 60kW, 80kW, 95kW and 115kW, with new cascade options up to 460kW. All products also come with a five-year warranty.

The boilers include a reliable heat exchanger with combustion system, which delivers high energy efficiency, as well a low NOx performance, contributing towards specifications that exceed Part L2 requirements.

Products also feature a newly developed control panel, ISR Plus, which offers full text

display of operation status with inbuilt weather compensation, summer/winter changeover and time control facilities for heating circuits and domestic hot water. These controls can be used with compatible room thermostats or can be fully integrated with building energy management systems.

The outside sensor, which is supplied as standard, allows the heating flow temperature to dictate the heating demand of the building. This enables the overriding RGB room controller to shut down the boilers if the building meets the set-point temperature, ensuring temperature remains at an optimum level. The

controller also provides frost protection, optimum start/stop and night setback for heating and domestic hot water.

All components that require maintenance, such as the burner, are easily accessible from the front with optimised burning and suction silencers contributing to a quiet operation.

Boilers from the range can also be situated in a modular arrangement, which allows optimum system performance, regardless of variable demand brought on by influencing factors such as time of day, type of occupancy and external weather conditions. we&e

Non-domestic RHI phase 2 extensionThe Heat Pump Association has welcomed the extension of the RHI and

the inclusion of air source heat pump technology

Non-domestic air source heat pumps are now entitled to RHI payments

June/July 2014 | water energy & environment 31

The HPA (Heat Pump Association) has welcomed the announcement of the

extension to the Non-Domestic Renewable Heat Incentive (RHI), which is a further demonstration of the hard work that trade associations, including the HPA, have invested in working with the Department of Energy & Climate Change and other agencies such as Ofgem.

This second phase of the non-domestic scheme significantly increases financial support for eligible ground source heat pump (GSHP) systems and, most importantly, now includes air source heat pumps (ASHP), which at 18 months since initial launch is long overdue.

HPA president Tony Bowen said: “This is a

clear demonstration of the commitment and resolve of trade associations including the HPA to work with DECC for the continued development and extension of the RHI schemes, in this particular case non-domestic.

“We shall continue our work post launch with both DECC and Ofgem to further extend and improve both the domestic and non-domestic schemes.”

It is widely thought that this long-awaited extension (Phase2) to the non-domestic scheme should go some way to help to redress the very clear imbalance in the scheme whereby biomass dominates the small and medium sectors and, as a result, has had tariff reductions for new entrants applied several times since initial scheme launch in

November 2012. The increase in the GSHP tariff from 4.3 p/kWh to 8.4 p/kWh for the first 1314 full load equivalent hours (or 2.6p/kWh thereafter – see www.heatpumps.org.uk for further explanation and an example calculation) and the first inclusion of ASHP

in the scheme (@2.5p/kWh) will undoubtedly have a significant effect on the uptake of these technologies. The only question is, will it be sufficient to grow the markets sustainably and/or meet EU renewable energy targets? we&e.

T he benefits of including low-carbon heating technologies in new heating

systems are well understood. Not only other significant energy and carbon savings, this approach can also help to gain planning permission or BREEAM points.

However, it also poses a challenge, because different low or zero carbon (LZC) technologies may be used – such as heat pumps or solar thermal – and combined with conventional heat sources such as gas or oil-fired condensing boilers as back-up.

In such cases the key is to design the system so that the contribution from the boiler(s) is minimised. Surprisingly, this isn’t always the case – very often because the performance expectations of the LZC technologies are relatively low. Consequently, the return on investment (ROI) calculation predicts an extended payback period that doesn’t satisfy the financial criteria of the project.

In our view, the default approach should be to design the system to take advantage of LZC opportunities and maximise their performance, thereby radically altering the ROI calculations and increasing the use of LZC technologies. In parallel, it’s important to maximise the efficiency of any conventional heating technologies being used in the system. To that

Integrating to the maxIntegration of different heat sources within a heating system is becoming increasingly common. Graham Rodd explains why design is the key to achieving maximum benefits

end, the hydraulic design and the control strategy of the project are both critical.

For example, pre-heating water with a heat pump or solar thermal system will raise the return temperature of the water in the system. Therefore, if a condensing boiler is also being used, the amount of condensing will be reduced so that energy is potentially wasted.

The answer is to use a thermal store as a buffer with very good control of stratification. In this way, the different temperature layers are maintained and each heat source is used to maximum benefit.

Of course, the precise design will need to take account of the specific requirements of the project. Where there is a swimming pool, for instance,

it will act as a large heat sink with relatively low operating temperatures, so there may be no need for a thermal store.

Boiler/heat pump hybridsGiven the considerable variation in solar irradiation levels in the UK, there tends to be more interest in using heat pumps as the LZC element of a project, and we have seen growing demand for hybrid boiler/heat pump units. Combined air source/ground source heat pumps are also gaining popularity.

In our experience, how efficiently such systems work depends on how the system is configured around the bivalence point (that is, at what external temperature the system switches to alternative heat sources).

For example, in a typical scenario, the bivalence point for an ASHP may be at an ambient temperature of 5°C. Below this temperature the conventional approach is to switch to a boiler. An alternative is to work with a

variable bivalence point and a good control configuration to maintain an acceptable Coefficient of Performance (COP) while using the ASHP to meet part of the load and top up with the boiler.

Another example is with GSHPs, where the cost of excavating groundworks (typically about £1,000/kW) is often prohibitive, especially as each area of ground needs time to recuperate once heat has been extracted. One way to reduce costs is to also include an ASHP to reduce the running time of the GSHP, so that recuperation time is minimised, as is the extent of groundworks.

In our experience, running the ASHP when ambient temperatures are above the bivalence point will reduce groundworks by about 25%. This figure rises to nearer 50% when the ASHP is used below the bivalence point to supplement the GSHP. we&eGraham Rodd is managing director of MHG Heating

Implementation services accredited supplierIndustrial process heating specialist Babcock Wanson UK has been awarded the status of Carbon Trust Implementation Services Accredited Supplier for its Thermal Fluid Heating solutions.

The accreditation scheme uses the Carbon Trust’s 10 years’ experience advising UK businesses and public sector organisations on means of reducing their energy consumption. It makes energy efficiency easy by matching customers that need to implement energy efficiency projects with good quality, established, equipment suppliers that have a track record of delivering energy saving projects.

Babcock Wanson applied for accreditation as an independent verification of its commitment to providing energy efficient process heating solutions. The company provides a comprehensive range of thermal fluid heaters with integrated gas, oil or dual fuel burner to meet the needs of modern industry. A thermal fluid heater is a closed circuit, no-loss system, so heat loss is minimal, which makes it highly energy efficient. A typical energy saving when using a thermal fluid system can be as high as 20-50% when compared with the transfer of the same amount of heat using traditional steam boilers, especially for processes where the energy from the condensate cannot be easily

recovered. Thermal fluid systems precisely match fuel input to plant energy requirements for high efficiency. With lower energy input demand comes lower total exhaust emissions, so there are also environmental benefits.

Responsive heating for The LeadenhallThree Stokvis 1.5MW boilers fitted with Riello modulating burners have been supplied to The Leadenhall Building in the City of London to provide space heating throughout the building. Designed by Rogers Stirk Harbour & Partners, the 224m-high, 52-storey building has a distinct tapering shape. It is being constructed by Laing O’Rourke using building information modelling techniques and will incorporate retail outlets, a restaurant, two reception levels and 41 floors of offices. Plant rooms are located above the offices from levels 46 to 52.

The Stokvis Rex 160F boilers, fitted with Riello RS120 fully modulating burners, were selected by Crown House Technologies (CHt) working to a specification by consulting engineer Arup. More than 83% of the construction works for The Leadenhall Building took place off site.

In support of this strategy the boilers were delivered to CHt’s fabrication facility, where they were skid-mounted with pre-assembled gas and water pipework for ease of installation on site. They were then lifted into position on the 47th level of the building, arranged end-to-end to make best use of the plant room space available.

Softer landings for hydronic heating and cooling systemsThe new FloCon Watchman from SAV Systems combines the proven benefits of commissioning modules with electronic monitoring to support “soft landings” for hydronic heating and cooling systems. As such, FloCon Watchman provides visibility of performance at “zone level” rather than whole system level, so that problems can be quickly pinpointed and remedied. By operating in zones, it also makes effective sub-metering financially viable, compared with installing meters on each terminal unit.

SAV’s FloCon commissioning modules bring all of the control valves for a group of terminal units (eg fan coils, chilled beams) into one location. FloCon Watchman modules also incorporate SAV’s Watchman electronic flow measurement device. This enables continuous monitoring of flow rates, temperature differential (ΔT) and energy consumption for each zone of terminal units – thereby providing better visualisation and understanding of each zone’s performance than would normally be possible.

Each FloCon Watchman module includes a 2-port actuated control valve and a differential pressure control valve to ensure that all 2-port control valves operate with excellent authority. FloCon and FloCon Watchman modules are also available for use with hydronic systems operating with ultra-low flows.

For more than half a century, Tamoin has been developing capabilities in the

provision of engineering services including operation, overhaul and maintenance of industrial plant. The company was originally established in 1956 in Spain, and is now active right across Europe and Central and South America.

Tamoin is involved in most industrial areas, including chemicals and petrochemicals manufacturing, natural gas production and power generation. At Cargenbridge in Dumfries, Scotland, Tamoin UK manages a boiler facility that is owned by Scottish Power and supplies steam to the adjacent DuPont Teijin Films factory. Tamoin has outsourced the boiler water treatment to Veolia Water Technologies, formerly known as ELGA Process Water.

The Cargenbridge plant has four 17bar shell boilers supplying an average 14 tonnes per hour of steam, 50% of which is returned as condensate. Make-up water for the boilers is taken

theenergyst.com

Boilers & Burners

Joined-up boiler water treatmentVeolia Water Technologies initiated a water treatment programme for maintenance and supply of equipment and conditioning chemicals, which resulted in boiler treatment costs reduced by 30%

from Scottish Water’s local mains supply, which has total dissolved solids (TDS)concentration of about 150mg/l and total hardness about 60mg/l CaCO3. The mains water is treated by filtration, softening and reverse osmosis to produce a soft make up water of TDS around 10mg/l and this is blended with the returned condensate. The resulting feed water is then conditioned with chemicals including an oxygen scavenger, alkali for pH control, a phosphate based scale preventative and a volatile amine for condensate neutralisation.

The treatment plant was originally supplied and serviced by Veolia Water Technologies, but chemicals were supplied and monitored by another specialist. This meant that there were two companies involved in maintaining boiler water quality, with the potential for uncertainty over responsibility. There was clearly a significant advantage to Tamoin in having a fully “joined-up” approach with a single point of responsibility.

As one of few companies with in-house capabilities in both water treatment plant and conditioning chemicals, Veolia Water Technologies

was able to offer a complete bespoke package covering the filter, softener, reverse osmosis plant and the supply of chemicals from its Hydrex range. In addition to service support for all equipment and chemicals, this package also includes the support of a Hydrex service technician to provide weekly visits to test the boiler water and make any necessary adjustments to chemical dosing to control boiler water conditions in accordance with BS2486.

The contract also includes boiler log book maintenance, operator training, technical support and attendance at annual boiler inspections, as well as annual servicing of the filtration, softening and reverse osmosis plant. Chemicals are delivered in intermediate bulk containers and pumped over into existing storage facilities.

Tamoin’s site manager, Jason Candlish, is pleased with the consistent results from the new servicing regime. He has a single point of contact for all his boiler water requirements and by having a stronger presence on site, Veolia Water Technologies is able to maximise efficiencies and fine tune chemical usage.

Its weekly visits also provide a means of monitoring the performance of the treatment plant and optimising its performance. Not only does this provide an holistic approach to boiler water side operation, but the improved performance and reduced administration has resulted in a 30% reduction in costs by comparison with the original operating regime. we&eveoliawatertechnologies.co.uk

Tamoin is involved in most industrial areas, including chemicals and petrochemicals manufacturing, natural gas production and power generation. At Cargenbridge in Dumfries, Scotland, Tamoin UK manages a boiler facility that is owned by Scottish Power and supplies steam to the adjacent DuPont Teijin Films factory. Tamoin has outsourced the boiler water treatment to Veolia Water Technologies, formerly known as ELGA Process Water.

The Cargenbridge plant has four 17bar shell boilers supplying an average 14 tonnes per hour of steam, 50% of which is returned as condensate. Make-up water for the boilers is taken

Boilers & Burners

Joined-up boiler water treatmentVeolia Water Technologies initiated a water treatment programme for maintenance and supply of equipment and conditioning chemicals, which resulted in boiler treatment costs reduced by 30%

from Scottish Water’s local mains supply, which has total dissolved solids (TDS)concentration of about 150mg/l and total hardness about 60mg/l CaCO3. The mains water is treated by filtration, softening and reverse osmosis to produce a soft make up water of TDS around 10mg/l and this is blended with the returned condensate. The resulting feed water is then conditioned with chemicals including an oxygen scavenger, alkali for pH control, a phosphate based scale preventative and a volatile amine for condensate neutralisation.

The treatment plant was originally supplied and serviced by Veolia Water Technologies, but chemicals were supplied and monitored by another specialist. This meant that there were two companies involved in maintaining boiler water quality, with the potential for uncertainty over responsibility. There was clearly a significant advantage to Tamoin in having a fully “joined-up” approach with a single point of responsibility.

As one of few companies with in-house capabilities in both water treatment plant and conditioning chemicals, Veolia Water Technologies

was able to offer a complete bespoke package covering the filter, softener, reverse osmosis plant and the supply of chemicals from its Hydrex range. In addition to service support for all equipment and chemicals, this package also includes the support of a Hydrex service technician to provide weekly visits to test the boiler water and make any necessary adjustments to chemical dosing to control boiler water conditions in accordance with BS2486.

The contract also includes boiler log book maintenance, operator training, technical support and attendance at annual boiler inspections, as well as annual servicing of the filtration, softening and reverse osmosis plant. Chemicals are delivered in intermediate bulk containers and pumped over into existing storage facilities.

Tamoin’s site manager, Jason Candlish, is pleased with the consistent results from the new servicing regime. He has a single point of contact for all his boiler water requirements and by having a stronger presence on site, Veolia Water Technologies is able to maximise efficiencies and fine tune chemical usage.

Its weekly visits also provide a means of monitoring the performance of the treatment plant and optimising its performance. Not only does this provide an holistic approach to boiler water side operation, but the improved performance and reduced administration has resulted in a 30% reduction in costs by comparison with the original operating regime. we&eveoliawatertechnologies.co.uk

The Belimo Energy Valve and room controller CR24-B1 are the key components in

a Macedonian pilot project in Skopje to determine the energy efficiency of buildings.

The experimental set-up at the Institute of Forestry was able to demonstrate that, with the implementation of meaningful renovation measures, consumption of primary energy could be reduced by 20% by 2020 in comparison with the expectations projected for 2007 – as outlined by the 2012/27/EU Directive. With the Belimo Energy Valve, also the current energy consumption values and the optimisation potential of the system are known at all times.

In addition to forestry subjects, the institute at the St Cyril and Methodius University also performs research on aspects of environmental and energy efficiency. In the case of this pilot project, the intention was to investigate potential heating energy savings in the institute’s own building. The basis for the experimental set-up was the ISO 50001:2011.

Two points were defined as conditions: • energy consumption can

be analysed and regulated in accordance with work conditions (working hours, working days, room temperature etc);

• the energy consumption of the current month is known

Transparent system monitoringProducts from technology company Belimo are playing a central role in a pilot project in Macedonia to investigate potential heating energy savings

at all times, in contrast with the retrospective invoice data of the operator.

Belimo’s solutionThese customer requirements correspond to the features of the Belimo Energy Valve. It

measures, regulates, balances and saves

all measurement values. Because a web server is integrated in the valve actuator, the data can

be viewed and analysed for a

period of 13 months through any internet

connection with the Belimo Energy Valve tool. The two-way control valve that was previously used in the primary part of the heat supply facility was therefore replaced with the Belimo Energy Valve in the DN65 dimension. The valve is controlled with a room

controller CR24-B1 (master controller with PI response) that is installed in a reference room. The nominal room temperature of 21°C was lowered to 16°C on weekdays after 3pm and on weekends.

From 7 February to the end of April 2013, the Energy Valve used sensors to continuously measure, balance and control the flow and temperature values in the supply and return lines. With transparent energy monitoring it was possible to analyse where and how much energy in the heating system was being used. The optimisation potential was quickly determined: the available energy can be used according

to actual requirements and energy consumption can be reduced significantly.

The optimisation of the heating periods and temperatures with the aid of the Belimo Energy Valve led to energy savings of ≥ 30%, as could be seen on the invoices of the local heating supplier (Balkan Energy Group BEG).

The specifications of the EU Directive 2012/27/EU were fulfilled. The customer has transparent energy consumption values at their disposal at all times and can project budgeting for the coming heating season.

After three months, the evaluation of the energy consumption values revealed considerably improved economic efficiency for the converted heating system, see table below.

Customer satisfactionAfter the heating period was over, the experimental results achieved with the Energy Valve at the Institute of Forestry were analysed and presented to the university’s management.

Vice-rector Nikola Vasilevski emphasised the use of modern, energy-efficient technologies was of great value. He would like not only to continue cooperating with Belimo in this area but extend it further. Based on this pilot, the plan is to roll the project out across the whole university. we&e

Lighting

As a leading Scottish newspaper, the Daily Record is bought by an

average of 253,500 people, which means its distribution centre has heavy demands to meet. Hundreds of lorries pass through the distribution centre to collect the newspapers and deliver them throughout Scotland.

Yet the lighting within the distribution centre had become a cause for concern. The existing light fittings were not enclosed, making

them vulnerable to the harsh Scottish winters. A new, weatherproof lighting solution was needed to keep the distribution centre properly lit and running at full speed.

“We discussed the problem with our local branch of City Electrical Factors and considered our options,” comments David Beagan, chief

engineer at the Daily Record. “We’d used Tamlite lighting products before – they’ve been installed elsewhere in our factory and to light the outside of the building. We decided Tamlite’s HILUX product fit our specifications best.”

The Daily Record’s maintenance team installed 44 of the HILUX units – a

straightforward installation process that did not disrupt the day-to-day running of the distribution centre.

HILUX is a shallow-profile, high-performance luminaire for long-lasting, energy-efficient fluorescent lamps. Each HILUX light fitting is fully enclosed, making them robust enough to function in cold and weather-beaten industrial environments.

“The light quality from the HILUX product has been very good,” comments Mr Beagan. “We’re pleased with the overall quality of the Tamlite lighting. It has really met our needs as a weatherproof, long-term solution for the distribution centre. Now we know we’re getting good, energy-efficient lighting – without the maintenance worries.” we&e

International growth for High Technology LightingHigh Technology Lighting, supplier of energy-efficient lighting solutions for retail and commercial spaces, has experienced substantial international success in the past six months, after expanding its international operations as part of the company’s long-term growth strategy.

The company has supplied fittings to Kuwait, Cyprus, Poland, Czechoslovakia, Belgium and Russia directly, as well as to Sweden, Australia and the UAE through distribution partnerships.

The job in Russia was a particular highlight for High

Technology Lighting, with the company supplying 120 of its Quartet Uno fitting to a church. The fitting incorporates leading LED technology from Xicato’s Artist range, a favourite of museum curators as the module gives off a natural level of light and is perfect for use in buildings with high ceilings, great also for a church.

Thomas Holgeth, joint managing director of High Technology Lighting, says: “We are extremely pleased with our international success over the last six months. The installation of our technology

in the church in Russia was a particular high and the new lighting looks fantastic. We are looking forward to similar jobs throughout the rest of 2014 across the world.”

High Technology Lighting’s Quartet LED range is, by all reports, the most compressive product offering of its type in the world.

MBA cock-a-hoop at savingsAn installation of Goodlight LED lighting for the Malta Basketball Association has

resulted in dramatic savings and reduced energy consumption

the Malta Basketball Association (MBA) is achieving energy savings of

75% following the recent installation of Goodlight LED lighting at its new training pavilion.

Designed and made by LED Eco Lights, the new system was supplied and installed by INLED, the company’s exclusive distributor in Malta. With a number of basketball clubs in Malta catering for both male and female players, ranging from under 14s to national level, it was clear there were insufficient full-size courts to meeting the growing demand. Accordingly, the association decided to invest in the construction of a pavilion alongside the existing national stadium to accommodate two modern, full-size basketball courts.

Following thorough evaluation of the lighting needs and a tender process, INLED was commissioned to supply Goodlight 100W LED high bay lighting. The

system relies on a series of fittings installed at a height of 10 metres above the playing surface.

The MBA had originally planned to use traditional 400W metal halide fittings for the new pavilion but were so impressed by the performance simulation and fast payback calculations provided by INLED that the decision was made to specify the Goodlight LED solution.

“This project was crying out for Goodlight,” says INLED managing director Saviour Bone. “We were easily able

to demonstrate that we could achieve 75% energy savings and full payback within two years without compromising on the quality of lighting. In fact, Goodlight LED high bays provide superior brightness to the metal halide alternatives that consume four times as much electricity. Also, because Goodlight LED fittings and lamps are maintenance-free and guaranteed for five years against failure, enormous savings are made by not having to use expensive access equipment to replace failed lamps.”

Another aspect of the Goodlight LED high bay lamps is their “instant on” feature. Traditional metal halide lamps need to be turned on for a period of time before reaching the correct temperature to provide adequate illumination.Goodlight can be turned off at any time, for any reason, and will provide immediate brightness at the flick of a switch.

Goodlight LED’s typically consume between 70% and 75% less energy than their traditional counterparts, with no reduction in lux levels and with a lifespan that is at least five times longer. The Goodlight LED range is an ideal alternative to traditional tubes, spot lights, CFL PL lamps, 2D lamps, SONS, metal halides and floodlights to dramatically cut energy consumption, reduce costs and ensure compliance with new legislation being introduced around the world. we&e

Courting success: the MBA is achieving savings of 75%

German motoring giant BMW is making a lighting control system

that has lowered its energy costs by about 30% and is based on WAGO components a company-wide standard.

Munich-based BMW has been a permanent member in the “Dow Jones Sustainability Group Index” since 1999. And to ensure that it will continue to be part of the stock index for companies exercising sustainable business practices in the future, it is continuously working on programmes for active energy optimisation.

Building lighting under scrutinySubstantial optimisation had already been achieved in this sector in the recent past using a new central I&C (instrumentation and control) system. The next logical step was then to modernise the hardware at the automation level. And this had to be done implementing a solution that can be used both in newly constructed production facilities, which are equipped in the field with DALI and EnOcean, and in

theenergyst.com

BMW drives sustainabilityBMW has reduced its energy costs thanks to a new lighting control system. Jürgen Pfeifer, system advisor for industrial automation at WAGO Kontakttechnik, explains

retrofit projects in which the existing, conventional technology is to be retained.

The fact the two technologies, ie old and new, can be easily combined was a reason for BMW’s Jörg Tratzl, the responsible electrical systems planner, ultimately deciding on components from WAGO. Another reason was the user-friendly handling that WAGO developed for BMW for controlling I&C operating devices.

The new lighting distribution connector puts focus on the needs of the end user. In contrast to the lighting distribution connectors used up to now, the electrical installation specialist does not have to perform complicated programming, neither during commissioning, nor during his everyday work. Instead, the area-oriented software can be adapted to individual needs using only the parameter settings – and this via the graphic user interface with any Internet browser. This saves time on the one hand and also eliminates the need for additional know-how; with

two-fold positive results; energy costs and the expenses associated with engineering can both be markedly reduced.

The basis for this is the WAGO-I/O-SYSTEM 750 Ethernet controllers, which are installed in the local control cabinets in the production facilities with I/O modules for DALI, EnOcean and standard analogue and digital inputs and outputs. They exercise control over each and every electronic ballast.

This allows the lighting to be automatically dimmed in accordance with the defined lighting planning, yielding energy savings while fulfilling strict operational requirements at the same time. A further advantage is also achieved using DALI: instead of having to activate entire circuits, so-called short addresses are used to control each individual light. The individual control nature achieved using this system can be used to combine short addresses into groups, enabling virtual rooms to

be illustrated on screen via WAGO Web visualisation, which can then be controlled individually, in the same manner as physical rooms.

For BMW production facilities this means that lighting can be optimally adapted for construction work or building re-assignment

with only a few clicks of the mouse.

The lighting distribution connectors standardised by BMW have proven

themselves in more than 100

installations at locations within the

corporate group. Simple configuration of the WAGO control system via an internet browser has reduced the commissioning time for each lighting distribution connector from several days to only a few seconds. Relays can be installed and removed with just a few turns of the hand using pluggable sockets.

Replacement of the hardware is the only activity that still needs to be performed manually at BMW, stresses Mr Tratzl. He says: “Since the WAGO Ethernet controllers communicate directly with the plant management software, this enabled us to nearly perfect this workflow. The exact position of defective lighting is reported, operating hours counters are reset after replacement of the components and the brightness levels are adjusted automatically.” we&e

When it comes to optimising energy performance, the way that

equipment is controlled and connected with other services is important. This is true for all building services systems – and perhaps especially the lighting, heating and ventilation.

The choice of control system is critical in achieving the required levels of performance and functionality. However, it is important to be aware that not all control systems are equal, so the design and application of the system needs to be aligned to the requirements of the project. This may involve enabling different systems within the building to work with each other and complement each other’s performance. For example, the ability of the lighting management system to connect, interact and share information with other systems in the building can deliver significant savings in energy consumption, as well as improved comfort.

A lighting management system typically has presence or absence detectors located throughout a building. The sensors monitor occupation and relate lighting to use of individual areas, yet these same sensors can share this data with other connected systems. No longer do buildings need to be uniformly lit, heated or cooled. Instead, the lighting network creates an interactive map of usage so that energy is applied efficiently, economically and sustainably.

Connected systems are easy and cost-effective to achieve and yet there are still far too many buildings where

LIGHTING

Interacting with interoperabilityConnected systems with open control protocols provide the flexibility to integrate different systems for maximum performance and efficiency. Stephen Woodnutt of Delmatic explains

the various sub-systems – lighting, power, HVAC and life safety – all operate separately or have limited abilities to communicate though custom, hard-to-maintain gateways.

Open protocols make it simple for systems such as lighting, window blinds and comfort cooling to work together to achieve the best balance of comfort and energy consumption without a price penalty. Products using proprietary protocols can only interface in a limited way through gateways, yet products and systems using open protocols can share

networks, share hardware and share knowledge.

Furthermore, by conforming to published standards, devices from various manufacturers become instantly interoperable – which means they can work seamlessly together on a network without needing gateways to translate the data.

On the subject of cost, there is a common misconception that interoperability is more expensive than using closed systems. In fact, a number of projects have illustrated that open systems not only achieve substantial savings over the lifetime of a building but also provide initial capital costs savings compared to proprietary systems.

Another benefit of open protocol systems is that they are fully scalable so it is easy to extend or reconfigure systems in relation to changes in building usage – or to add extra functionality as new technologies become available. This element of “future-

proofing” is invaluable as it enables buildings to maintain the levels of efficiency they were originally designed to achieve throughout their life. As many readers will be aware, it is an unfortunate fact that the energy efficiency of the building often decreases significantly within a few years, or even months, of it being occupied.

Also, the intelligence in open protocol systems is distributed and data is stored in each module or device, so there is no reliance on central points or outstations.

It is worth noting that, beyond the integration issues, a “closed” system also carries the risk that the manufacturer will withdraw support in the future. This is not the case when open protocols are used.

For example, when the lighting control modules at a global financial services provider in the City of London failed, the building owner discovered these units were obsolete and support had been withdrawn by the original manufacturer. Delmatic was able to offer replacement modules that provided the same control features, connected to the existing system buswire and exploited the benefits of open protocols by forming an interoperable part of the original installed system.

Fundamentally open, interoperable systems are also about choice and greater simplicity. Not only do they avoid the issues described above, they also free building owners from being locked into lengthy and costly service and upgrade agreements from a single vendor. we&e

Lighter side of emergenciesWhen selecting emergency lighting it is important to be aware of the latest

developments. Mackwell’s James Beresford explains

Many readers will be aware of recent technological advances

that have influenced the selection of general lighting, but perhaps not so aware of similar advances in emergency lighting. Wider use of LEDs probably won’t come as a surprise but automatic monitoring and testing, as well as wireless communications, also have an important role to play.

The basics, however, remain the same. Fundamentally, the role of the emergency lighting is to come on automatically when the building experiences a power outage, ensuring there is sufficient light for people to find their way around safely.

Perhaps one of the major differences between general and emergency lighting is that in the latter energy efficiency is a secondary consideration, with safety being the principal function. Nevertheless, the adoption of LED light sources for emergency lighting has enabled the power consumption of these systems to be reduced, though the main financial savings arise from the introduction of automated systems that simplify monitoring, testing and ongoing maintenance.

There are also aesthetic benefits. Unfortunately, in the past compliance with emergency lighting legislation has often achieved at the expense of the aesthetic appearance system. However, many luminaire manufacturers are now introducing standalone LED solutions that complement their general lighting products so that

the harmony of the visual appearance is maintained across all of the lighting.

Monitoring and testingMaintaining a compliant emergency lighting scheme is often overlooked by building owners but it is just as important as a fire alarm system. There are legislative directives for emergency lighting that are implemented by building control officers and emergency lighting is a legal obligation. Some buildings require a licence from local fire authorities and maintenance and testing log books must be kept. Using a self-test or reporting system reduces the burden of monitoring and testing the emergency lighting system.

The introduction of self-testing emergency luminaires was the first step in making compliance easier by routinely testing the fundamental aspects of the emergency lighting luminaire and reporting status using a visual indicator such as a flashing LED. However, these self-testing emergency light fittings still require someone to walk around and check the individual indicators. The latest products take automation a step

further by centralising the monitoring and testing of emergency lighting. There are proprietary systems available but I would recommend using DALI

multiple sites, a permanent software interface is ideal. This will flag up faulty light sources, batteries and components so that any issues can be quickly remedied.

While there is clearly a nominal monetary cost associated with installing a monitoring system, there are clearly significant savings in cost of ownership when compared with the cost of employing someone to visually monitor each luminaire individually.

The underlying principle for addressing all of these issues is to include emergency lighting early in the specification process and look carefully at the required functionality and the elements – including the emergency lighting components – that will deliver the required performance. we&e

as it is the most commonly used protocol for general lighting schemes as well.

These systems can be operated with or without a permanent connection to a computer. For relatively small standalone sites there is generally no need for a permanent connection, just the ability to connect one for configuration, viewing and printing reports will usually be sufficient. In larger buildings, or for monitoring

Although a legal obligation, emergency lighting can still complement general lighting schemes

Delmatic is supplying a DALI lighting management system for the University of Greenwich’s new School of Architecture, Design & Construction. The system enables individual addressing, switching, dimming and monitoring of DALI luminaires, in conjunction with presence-related and daylight-linked control of lighting groups from DALI presence detectors and multisensors.

The 16,500 m2 Stockwell Street development comprises two linked buildings with internal courtyards allowing daylight and natural ventilation into the spaces. The buildings are designed to achieve high standards of sustainability to meet the criteria of BREEAM “Excellent” and incorporate elements such as energy-efficient systems, solar panels and “living roofs”.

Lighting is controlled throughout the building, using different control strategies in different areas. Many of these areas use suspended luminaires, with Delmatic’s DALI buswire modules enabling individual addressing, switching and dimming of the luminaires via a common Dali buswire. DALI multisensors and presence detectors are installed throughout DALI scene-set panels are used extensively to provide local scene selection and adjustment of lighting levels. Solenoid water valves in the toilets are switched via a Delmatic DALI One Relay which relates water use to occupancy of toilets.

LEDs reduce costs and carbon for schoolE.ON has worked with Chipping Norton School to help it reduce energy costs and carbon through a phased LED lighting refurbishment programme. It replaced 460 inefficient lights with LED luminaires specifically tailored to suit educational environments. Consuming significantly less energy with a longer life, this resulted in more than £8,000 of annual savings including 33.8 tonnes of carbon while providing a whiter and brighter quality of light for staff and students. Daylight and motion controls were also installed where needed enabling greater usage control and energy savings.

Much ado about lightingTheatres and performing arts venues have expressed concern about new EU laws restricting supplies of traditional incandescent bulbs, saying they are vital to ensure tailored production lighting. E.ON worked with Nottingham’s Royal Concert Hall to replace its auditorium lighting with a more efficient LED system.

The solution saves more than £16,000 annually in energy bills and maintenance costs, delivering carbon savings of 104 tonnes. The system requires minimal upkeep after installation adding further convenience and cost savings.

The pioneering solution designed by E.ON with Projection Lighting and DES Electrical saw more than 500 old-style incandescent light fittings replaced with energy efficient, long-lasting LED alternatives while simultaneously meeting the style and artistic requirements of the concert hall’s auditorium.

high bay PiR detector for industrial useCP Electronics’ EBDHS-MB luminaire mount high bay PIR presence detector range provides high sensitivity and long range detection, sensing movement up to 40m at a 15m mounting height. The detectors are ideal for high bay lighting control in areas with demanding spaces and increased mounting heights such as warehouses and factories, and are simple to retrofit to commercial luminaires and basic battens.

The EBDHS-MB detects movement using its PIR sensor, automatically switching lighting on and, when the area is no longer occupied, switching lighting off after an easily adjustable time out period. All functionality is fully programmable via an infrared handset. The detectors are available in three options: switching (PRM), Direct Dim (DD) and analogue dim (AD), all of which will switch incandescent, fluorescent, compact fluorescent and LED light sources. The direct dim model will control DALI or DSI digital dimming ballasts and the analogue dim is designed for variant control 1-10V dimming ballasts.

The EBDHS-MB is IP65 rated as standard and therefore ideal for outdoor use as well as wet and wash-down areas. A selection of fixing washers are supplied as standard to aid fitting to a variety of luminaires.

Milton Abbey School is installing a range of

measures, including a biomass boiler, water harvesting technology and air source heat pumps to save 3.3 million kWh of energy, reducing the school’s carbon footprint by 1,000 tonnes.

The measures, to be implemented by EIC – part of Utilitywise, follow an in-depth audit of the school’s energy use, and will provide an annual saving of £330,000 on the school’s energy bill. Underpinning the project is a finance package sourced by EIC as part of the overall energy solution strategy.

Julian Litchfield, bursar at Milton Abbey School, says: “The EIC team were refreshing in their approach and explored a number of options to reduce our energy costs and utility consumption. Things have progressed smoothly and together we’ve developed a co-branded logo with the tag line ‘Mission for Energy Efficiency’ that was launched at the Friends of Milton Abbey School Summer Fete on 7 June. We are enjoying working alongside EIC and the benefits have been varied, from cost savings and efficiency gains to practical links to our students’ education.”

The Energy Solutions team at EIC was brought in by Milton Abbey School to advise on ways to reduce the school’s energy consumption. Through ongoing discussions with the bursar the remit of the project has grown to involve a wide range of activities –from a simple and effective

Lessons in energy reductionPupils and teachers at an independent school in Dorset have taken an innovative approach to reducing their energy consumption and carbon footprint using a finance package sourced by EIC

pool cover to support with energy and oil tendering. The impact on students has not gone unmissed either and the project will provide numerous opportunities for pupil involvement – from classroom-based activities to learning more about a career in the energy sector.

Richard Tandy, energy solutions manager at EIC, says: “Our team is excited to be working in partnership with the headmaster, bursar, staff and pupils at Milton Abbey. The school has committed to making the scheme a success and together with our energy solutions team has actively engaged with internal stakeholders to instil buy-in, implement behavioural change and maximise efficiency gains. With energy prices expected to rise, being energy efficient is vital for schools and education providers to keep costs to a minimum.”

Further energy saving at Milton Abbey School is planned with Philips, a global leader in lighting, installing LED solutions

across the school’s estate including classrooms, offices, corridors, student accommodation and common rooms. The new lighting will provide students with an environment conducive to study and learning while also complementing the visual appearance of the buildings.

Jeremy Palmer, business development manager, education, Philips says: “Rising energy prices and the need to reduce CO2 are high on the agenda for many schools, colleges and universities, with lights accounting for around 20-25% of an education estate’s costs. We are working closely with EIC to identify areas where LED lighting can help Milton Abbey reduce its energy bills and ongoing maintenance costs, freeing up funding for other resources and school activities.”

In total, Utilitywise has more than 17,000 customers and manages an overall energy consumption of approaching 20TWh per annum. we&e

Combined Heat & Power

Lower temperatures for higher efficiencyWith the move to using a mix of different heat sources to achieve low carbon heating, system operating temperatures have become increasingly important. Lars Fabricius explains why

applies to many of the other heat sources that are now commonly being used. For instance, the optimum Delta T for gas-fired condensing boilers is 55°C/30°C; for heat pumps it is 40°C/35°C.

Additionally, lower return water temperatures are better suited to the relatively mild UK climate, where heating systems are often “over-sized” for the few very cold days we may experience each year.

delta t and CHPOne of the fundamental characteristics of CHP is that it generates both heat and electricity. You can’t have one without the other, so the overall energy and carbon benefits are inextricably linked to the run-time of the CHP plant. Consequently, where CHP is included in the system the design should seek to ensure

maximum run-times for the CHP plant by achieving a good Delta T and using a thermal storage vessel to store hot water when demand is low. In this way the CHP continues to operate and generate electrical power for use in the building or export the grid.

Consequently, achieving a good Delta T and using a thermal store are both critical elements in maximising the return on investment in CHP.

In ensuring that there is effective control of Delta T in the system, the first step is to reduce flow temperatures (eg to 70° rather than the traditional 80°). Then, as long as sufficient heat is removed from the system via the radiators, fan coils or other terminal units, this will reduce the return water temperature. This higher level of heat transfer to the space being heated will be greatly facilitated by reducing the flow rate, so that the water spends more time in contact with the air it is heating. The same principle applies when plate heat exchangers are used for the domestic hot water rather than hot water cylinders.

A further benefit of this is that variable speed pumps can be used to control this flow rate, as slower flow rates can be achieved with smaller, variable speed pumps, resulting in lower capital costs and reduced pump energy consumption.

To a non-engineer these measures may seem complex but they are in fact relatively simple to incorporate into the design of the system. we&eLars Fabricius is managing director of SAV Systems

to get the considerable benefits of CHP it is necessary to consider the most effective delta t (flow and return water temperatures) and design them into the system accordingly

in recent years there has been a move to combine a number of different heat sources within a heating

system. These include mini combined heat and power (CHP) units that have enabled many smaller applications to make use of this energy and carbon-saving technology, as well as heat pumps, solar thermal and the more traditional condensing boilers.

Crucially, these technologies operate more efficiently at lower return water temperatures than are traditionally used in UK heating systems – namely 80° flow/60° return. Consequently, there is a need for a rethink in the way such systems are designed. Indeed, this has recently been recognised by the Chartered Institution of Building Services Engineers (CIBSE), which advises in recent guidance:

“It is recommended that, for new systems, radiator circuit temperatures of 70°C (flow) and 40°C (return) are used, with a maximum return temperature of 25°C from instantaneous domestic hot water heat exchangers.”

As a result, the difference between the flow and return water temperatures (the “Delta T”) is, or should be, now becoming the overriding design consideration if the energy and cost-saving potential of the system is to be realised. In fact, where the anticipated energy savings from low-carbon heat sources fail to materialise, it is nearly always because the Delta T is wrong, in relation to the requirements of the heat sources in use.

Financial incentives for CHP usersA new service has been launched aimed at the one in six UK CHP customers that are substantially losing out by failing to register for the Combined Heat and Power Quality Assurance programme

e NER-G has launched a new service to ensure UK CHP users do not miss

out on thousands of pounds of financial incentives.

The new service manages compliance and certification for the Combined Heat and Power Quality Assurance programme (CHPQA), which is required as qualification for a raft of government incentives, particularly exemption from the Climate Change Levy (CCL).

The new certification service launches as latest data shows almost one in six UK CHP customers are failing to register for CHPQA and hence losing substantial financial benefits.

“On a small 200kW CHP system, failure to gain CHPQA certification would mean missing out on more than £10,000 per year in CCL relief, while a 2MW system would qualify for payments of approximately £100,000 per annum,” explains Heather Foster, corporate account manager for ENER-G Combined Power.

She adds: “CCL relief is available to CHP operators for energy consumed onsite. CHPQA registration is also the route to other tax benefits such as qualification for Enhanced Capital Allowances; preferential treatment in the EU Emissions Trading Scheme; exemption from business rates and exemption from the Carbon Price Support Levy.”

In addition, those energy efficient users that are maximising the heat output from their CHP for onsite consumption, but require

additional top-up heat from boilers, also have the facility to ‘extend the envelope’ and claim additional CCL relief on the additional gas consumed in that process. ENER-G can also advise on that separate claims process.

CHPQA provides a methodology for assessing energy efficiency and environmental performance of CHP systems and determines whether a site is classed as “good quality” CHP.

As part of the new service, ENER-G takes care of all aspects of a CHP scheme’s initial registration and annual certification process – managing performance and monitoring requirements and completing the paperwork through the CHPQA and Department of Energy and Climate Change to enable customers to gain CCL relief

and other financial benefits. In addition, by analysing

usage and efficiency of the system, opportunities for optimising technical performance may be identified to ensure maximum efficiency.

Ms Foster adds: “To achieve ‘good quality’ certification, schemes must achieve or exceed a Quality Index (QI) rating of 100, and power efficiency performance of greater than 20%, which are also designed to meet the requirements of the European CHP Directive.

“Our analysis determines these ratings by examining data for fuel used, power generated and heat supplied. Failure to achieve the threshold results in a scaling back of the fuel and/or electricity that will qualify for tax benefits.” we&e

T he Renewable Heat Incentive is the UK government’s world-leading

subsidy scheme to encourage switching from fossil fuel heating to renewable heating sources. Like all world-leaders it is not without imperfections and controversy.

The scheme was set up for non-domestic sectors (including multi-residential) and is just starting for the domestic sector with significantly changed criteria for approval and metering, which are not addressed here.

Maximising returns from biomassJohn Field of TEAM (EAA) explains how to make the most of returns from biomass Renewable Heat Incentive schemes

subsidy schemes. The answer highlights a critical issue: electricity is easy to meter and heat is not. Alongside that, heating systems have complex flows and usually involve traditional non-renewable heating plant – often in ways (like immersion heaters in domestic hot water cylinders) that have been taken for granted or even actively disregarded by the industry until you need to know whether the heat you are using is from a renewable thermal source which an electric immersion heater is not.

One thing is for certain, that the scheme is achieving significant momentum – unlike a certain other planet-saving scheme. An obvious reason for this is the high subsidy tariffs, which

determine how much you are paid by the government for each kWh of eligible heat output from your approved system. Another reason – more arguable – is that the Department of Energy & Climate Change and Ofgem have got on with the business of developing a scheme with pragmatic procedures to work around the bigger issues. This has a flip-side in that the application and approval processes are a little complicated; on the other hand the issues are substantial and one could challenge critics to come up with a better approach.

Of the renewable heat technologies covered by the scheme, solid biomass has been the undoubted front runner to date, receiving the majority of

the subsidy payments. Ground source heat pumps come in second and air source heat pumps are a late entry with some promise. Also included are solar thermal, biogas, deep geothermal, energy from waste and biomethane injection into the grid.

A universal theme has been that the relevant heat flows have to be metered (except for small fractions of system heat such as some buried pipework heat losses) and as metering air-transported heat directly is virtually impossible, the scheme concerns mainly water and steam-based heating generation, even if the heat is eventually emitted by air handling plant.

The scheme guarantees payments over 20 years (indexed upwards for inflation)

for properly metered and reported renewable heat from an approved system. Typical annual payments are £40,000 a year for medium biomass and £11,000 for small biomass. Multiply that by 20 years and you have some very big numbers by the standards of energy-saving support schemes.

A key concept in the above is obtaining approval from Ofgem, which manages the scheme on behalf of DECC. Potential installations have to be put through an application process, which is designed (and updated from time to time under a supposed simplification banner) to establish that the basic criteria for subsidy are complied with. It also ensures that the eligible renewable heat output can be metered and not increased either fraudulently or accidently by, for example, a retained gas boiler.

Application for biomass RHI approval is therefore a process requiring a wide range of information and evidence and a stated engineering base for the metering: in many cases other than the simplest, this application must be supported by an extensive engineer’s report (again with evidence) setting down how the metering achieves the scheme criteria. This report is titled the “Independent Report on Metering Arrangements” (IRMA) and has to be carried out by an “unbiased and impartial” engineer who can demonstrate suitable experience and expertise in heat metering.

TEAM has highly qualified engineers with a track record of delivering successful IRMAs and RHI applications for a wide range of public and private sector clients including supermarkets, police

authorities, NHS

and local authorities.The

application process is described at length in

publicly available documents on the Ofgem RHI website, which you can access directly and Ofgem has included some brave attempts at an introductory guide, with dos, don’ts and common errors.

Another thorny issue is the long-term picture for the subsidy tariffs. While the tariffs for approved schemes are fixed at the time of approval for 20 years (apart from upwards indexing) there is an uneasy period between committing to a renewable installation – issuing an order to a supplier/installer – and approval that follows design, installation, commissioning, gathering application information, submission to Ofgem, review by Ofgem, resolving any queries (most applications have queries) and approval by Ofgem. Much of this period comes after payment is due to the contractor which usually follows commissioning.

There is confusion and some misinformation about when the subsidy starts. An approved scheme receives payments for eligible heat in arrears on a quarterly basis according to metered data submitted quarterly to Ofgem by the scheme owner or their agent. The first quarter starts

at the time of the first meter reads, which are an important part of the submission of an application to Ofgem – if the application is approved without major queries the heat generated during the review and approval time is all subsidised and the tariff is fixed at the date of the first meter reads.

However, if significant changes are required to the installation or the application, the application must be re-submitted with a new first reading so the intervening heat subsidy has been lost.

Potentially more seriously, the tariff will be fixed from the new first meter reads and the tariff levels may have been reduced in the meantime.

The time taken for Ofgem to review applications is an important part of the above processes. Our experience has shown that this can be as little as two weeks for high quality applications and longer for more complex ones. The quality of the information provided makes a significant difference in avoiding review delays , formal queries and their resolution.

Concerning longer-term tariff projections, the term degression is used for

tariff reduction by Ofgem to prevent the number of applications mushrooming out of control, as they did with solar photovoltaic Feed-in Tariffs in October 2011.

DECC has set up a quarterly review process that looks at application levels and gives notice of any reductions (degression) of tariffs in the next quarter. These changes have been small to date, typically 5%, but that adds up over a 20-year project and there may be more than one degression before an installation is approved if approval times are extended.

DECC has a separate tariff review process, which has been used so far to increase selected tariffs in order to boost take-up of technologies that are not receiving RHI applications and subsidies.

The overall picture at present is therefore that this is a significant scheme with potentially large and long-term subsidy payments but that the application process requires considerable expertise, attention and

planning. Barring major revisions to the whole scheme (or worse), the process for longer-term review of tariffs is fairly well set down and can therefore be planned for. we&eTEAM is currently providing IRMA reports to clients ranging from large retail stores to housing associations across the UK.

Local government issues will also be covered extensively with representatives from Bristol City Council, North Somerset Council and Lancashire County Council. Topics to be explored include the challenges

of complying with changing energy legislation and practical insights into how councils are leading the way in energy efficiency innovation.

Speakers from The Carbon Trust will demonstrate the latest innovations in technology, products and practice that can be implemented to improve energy efficiency.

The Energy Leaders’ ConferenceSome of the topics to be explored in The Energy Leaders’ Conference, sponsored by The Energy Brokers, include the Electricity Market Reform and what financial effect it’s likely to have for business. Dieter Helm, professor of energy policy at University of Oxford, will be delivering one of the show’s headline talks on how to survive in our chaotic energy world.

Zyda Law will conduct

a session exploring how legislation really translates for business owners. The panel discussion will investigate how current policy and legislation could affect businesses, to help owners become more aware of the changes and how best to comply. Ms Law will also be offering practical advice on legal requirements and legislation within a new show feature.

The practicalities of shale gas extraction will be addressed in the seminar looking at the sustainability of fracking. A lively debate is anticipated with expert panellists including Doug Parr, policy director of Greenpeace, and Nick Grealy, principal of No Hot Air.

Despite a winter of floods misery and high-profile media attention, Defra

has again postponed the targetstart date to introduce compulsory legislation for SuD in England and Wales.

Local Authority Sustainable Drainage Systems (SuDS) approving Bodies (SABS) will not get the green light to start work approving SuDS

schemes on new developments from October 2014.

Instead, the letter to key stakeholders from Defra says, an announcement will be made in the summer which will set out in detail the plans for implementation of Schedule 3 of the Flood and Water Management Act. In addition, the government will still keep its promise to provide six months’ notice to enable SABS

to be ready to start work.“The government remains

committed to implementing SuDS at the earliest available opportunity, but not in a way that has any adverse impact on development,” the letter states.

Alex Stephenson, chair of the British Water Sustainable Water Management (SuWM) Focus Group and operations director of the UK Stormwater Division of Hydro International, comments: “Of course, nothing must stand in the way of increasing the UK’s housing stock and providing much-needed affordable homes. However, the perceived threat of any so-called ‘adverse impact’ of natural SuDS features for housebuilders must not be allowed to become the elephant in the room that paralyses SuDS implementation altogether.

“It has always been the case that well-engineered SuDS designs which combine manufactured systems with above-ground biodiversity

through natural features can – and do – provide cost-effective solutions for developers.

“Practical SuDS solutions using innovative proprietary systems can minimise land take and provide predictable water quality performance. Predictability is the key to delivering SuDS schemes that local authorities can have the confidence to adopt with clear maintenance schedules.

“With parliament in summer session between 4 June and 22 July, and a General Election on 7 May 2015, there is only a narrow ‘window’ for implementation, given a six months’ lead-time. Based on previous experience, further delays could not be ruled out.

“SuDS legislation is a vital element of measures to combat surface-water flooding. It is imperative that the government implements this legislation before the 2015 General Election.” we&e

taking fluid level measurement to a new level

Liquid volumes and flow rates can be continuously monitored using sensitive-yet-rugged new sensors that have recently been added to the range of piping systems specialist George Fischer.

The Type 2270 Ultrasonic Blind Sensor and Type 2260 Ultrasonic Display Sensor have been designed to offer both ease of installation and use, as well as a long low-maintenance life, and will find applications in the water, sewage treatment, chemical, manufacturing and processing industries. They are also suitable for measuring flows in culverts and spillways where flood monitoring is a priority. The sensors can be used in such roles as for calculating the dosage of chemicals required to control the pH value of a flow, for the accurate filling of storage tanks and in specialist treatments such as electro-plating.

The various sizes and outputs of the 2270 and 2260 models operate on the “time of

flight” principle, where a sound wave is transmitted from a point above the fluid surface and the time for the return signal to be received measured. This provides a reading of the level for the surface to an accuracy of +/- 0.2% of flow, with the sophistication of the technology allowing for wave height or the presence of dust and grease contamination.

The sensors can further recognise and allow for “disturbing objects” such as mixing paddles or ladders mounted on the side of tanks. The sender unit emits a narrow beam of sound to offer good echo densities – which can therefore cope with light foaming of the liquid – while the user can also pre-programme in different tank or channel shapes to facilitate the calculation of volumes. The construction of both units features the choice of polypropylene and PVDF materials for the casings, giving good resistance to aggressive environments and ease of cleaning.

The displays on the 2270 and 2260 are large and easy to read, while they use a 4-20 mA

signal strength to communicate with central monitoring devices, HART modem or process control systems. The 2270 can offer operating ranges of 4 or 6m while the 2260 encompasses models able to work up to a distance of 15m. Both can be used in proximity of process temperatures between -30 and + 90°C, while all units carry ATEX, CE and RoHs accreditation.

reduce pipe bursts with pressure loggerHWM-Water has developed a new data logger specifically for monitoring the water network for damaging pressure transients and combatting “water hammer”. With a five-year battery life, fast data sampling and large memory, HWM’s Pressure Transient logger is suitable for both long-term surveys and rapid troubleshooting deployments.

The new logger features an expanded 4GB of flash memory and uses advanced data compression algorithms to store up to eight billion readings on board. It can operate in the field for weeks or even months while still sampling rapidly enough (25Hz) to effectively monitor for pressure transients.

Conventional data loggers are unable to sample at a fast enough rate or store enough data to log and catch damaging pressure spikes, which may only last a fraction of a second. Despite – and in part because of – the speed and brevity of the event, these moments of extreme pressure differential are a major factor in reducing asset lifetime and causing burst water mains.

Sources can be traced but only after they have been identified, analysed and compared against other known network events, such as pump or valve activation, or high consumer activity. By reducing the severity of, or even eliminating, pressure transients in the water network, asset life can be significantly improved and burst frequency reduced. The Pressure Transient logger is supplied with a robust aluminium case containing the data logger, pressure transducer with quick-fit connector, download lead, software and full documentation.

Hot water recirculation pump without external coolingKSB Aktiengesellschaft of Germany has launched a new generation of hot water recirculation pumps for large industrial heating systems as well as forced circulation boilers and district heating systems. The horizontal, radially split single-stage volute casing pumps feature a back pull-out design. Their ratings and dimensions comply with ISO 2858; with regard to handling hot water, organic or synthetic heat transfer fluids, they also meet the technical requirements of ISO 5199.

The HPK-L pump series, which comes in 49 different sizes, can be operated at temperatures of up to 400°C without any additional cooling devices, and is designed for pressure classes of up to PN 40. This temperature resistance is achieved by means of a larger heat barrier, which separates the pump set’s hot operating section from the air-cooled mechanical seal chamber.

A fan impeller fitted at the pump shaft end generates a continuous flow of air between the large cooling fins surrounding the mechanical seal chamber. A service life of up to 25,000 operating hours is ensured by large, product-lubricated silicon carbide plain bearings fitted close to the impeller and by two angular contact ball bearings in back-to-back arrangement sealed

discharges the heat transfer fluid into the quench system. This enhances the system’s operating reliability, especially when using synthetic heat transfer oils of up to 400°C and with vapour pressures of more than 1 bar.

Discharge-side casing wear rings and drilled holes in the impellers help to reduce the axial thrust and thus the loads on the bearings.

With 49 pump sizes on offer, a hydraulic system

allowing the pump to be operated close to the best efficiency point (BEP) can be selected for almost every application. The pump manufacturer will also make sure to match every impeller to the required operating point before the pump is supplied to the customer.

Q&A

Mervyn BowdenThe managing director of Intuitive Energy Solutions on preparing for life without electricity, England’s lack of sporting success and heavy rock

Who or what are you enjoying listening to? (music, radio etc)Always enjoy the same stuff harking back to my misspent youth – hard and heavy rock music with loads of bass, which makes the building shake.

What unsolved mystery would you like the answers to?Why do sports teams labelled “England” never win anything?

What would you take to a desert island and why? (excluding loved ones and practical things)A stress ball – boredom is a terrible thing.

What’s your favourite film?Naked Gun – Lesley Neilson is hilarious.

If you could perpetuate a myth about yourself, what would it be?I’m really not as grumpy as everyone thinks.

What would your super power be and why?See unsolved mystery above, an England team that wins.

What would you do with a million pounds?Buy my kids places to live


– their generation has been badly let down by mine.

What’s your greatest extravagance?My exceptionally frugal BMW convertible.

If you were blessed with any talent, what would your dream job be and why?Being a creative musician to leave a lasting, but tuneful, impression on the world.

What is the best piece of advice you’ve ever been given?When the little man turns green you may cross the road.

What irritates you the most?Politicians and population density, not necessarily in that order.

What should energy users be doing to help themselves in the current climate?Improve their persuasion skills to get lots more cash to invest in energy efficiency projects.

water energy & environment’s regular section brings you an eight-week overview of the latest analysis of the power and gas markets from Energy Trader Daily. By Serge Mazodila

Following the Q1 market slump caused by the “winter that wasn’t”, the gas market

has continued to see losses as a result of healthy storage levels (80% full), above-average temperature forecasts and low demand levels.

This fundamentally Bearish picture has been tempered by high levels of market volatility, caused by the bubbling tensions between Ukraine and Russia, with traders’ focus drawn to the Russian reaction to Ukraine’s unpaid gas bills. Several rounds of talks between the opposing countries failed to reach a satisfactory conclusion, leading Russia to cut off gas supplies to Ukraine for the third time in the past decade.

Currently, gas is still transiting through the Eastern state to Europe, but the uncertainty surrounding these fl ows is leading to increased volatility in the gas market, particularly among prompt contracts.

gas-switching in the UK as power generators begin to favour gas-fi red power plants rather than coal, although this could also be seen as a necessary way to rid the UK grid of excess gas amid low consumer demand levels.

The geopolitical volatility seen in the gas market has led to some upward pressure and price spikes in the power market, but the movements appear to be supporting the price rather than increasing it, and recent weeks have seen a more sideways trend for the power curve, as traders adopt a “wait and see” attitude during this turbulent period.
