Gas Installer Register– contractors flextheir muscles

While the vast majority of heating installers and serviceengineers actively support the recently-establishedregister of gas installers, many are concerned that the

overseeing body – the Register of Gas Installers of Ireland (RGII)– is failing to police and enforce the spirit of the new requirements.

bs news recently conducted a survey among a representativesample of RGII members which revealed that, despite concernsabout registration costs and the cost of completion certs, theirbiggest anxiety was the ease with which unqualified, non-industryindividuals can gain admission to gas installer training schemesand subsequent automatic RGII membership.

Such is the level of concern among installers that over 100attended a meeting in Cork convened by the Cork Heating andPlumbing Alliance. There was also a meeting in Dublin which islikely to result in the emergence of a new installer representativebody for the Leinster region.

As so often happens, challenging times and situations lead topositive developments. The critical issues now facing gas installershas once again galvanised the industry. It would appear thatsooner, rather than later, bona fide installers throughout the entirecountry will speak with one voice in an organised, cohesive,manner.

That is something which is long overdue and which will benefitnot just installers, but the industry at large. It should be welcomedand supported by all, especially product suppliers, as aprofessional, orderly marketplace is also a profitable one. �

In variable air volumeHVAC systems, acomputerised controlprovides preciseadjustment of air volumeto meet changing systemneeds with maximumenergy efficiency. TheDwyer Series 641 fromManotherm offers theperfect solution.

Equipped with anoptional LED display forlocal indication of airflow,the unit provides

a quick, visualacknowledgement ofproper systemperformance.

The computer reacts toany change in velocity bysignaling the motor controlto increase or decreasefan speed to maintain therequired velocity. Takinginputs from other ambientcondition sensors, it willestablish a new requiredair velocity and signal anappropriate adjustment in fan speed.

Manotherm also has theideal solution to ensure

the efficient operation of heating and airconditioning systemswhich depend on thedelivery of a balanced,pre-determined airflow.Permanent measuringstations installed in theducts enable plantengineers locate andcorrect problems before they impact onperformance andefficiency.

Such stations can uselow-cost Dwyer Mark 11

manometers to indicate velocity pressure

directly as the differentialpressure betweenaveraging total and staticpressure tips. Themanometer is calibrateddirectly in CFM, as theduct area of the station is known.

A dial-type Dwyermagnehelic differentialpressure gauge can beused as an alternative if preferred.

The new TA-SCOPEmeasuring instrument has been specifically designed for use by consultants, contractorsand building engineers who needto access data and maintain thedesign temperature, flow andvolume in waterborne heating and cooling systems.

Removing the need forcumbersome monometer devices,the TA-SCOPE is a much smaller,wireless, handheld and user-friendly instrument designed toverify, measure and balance the flow, differential pressure,temperature and power ofcomplex systems efficiently.

Hydronic networks can becreated with the TA-SCOPE,which integrates with TA-Balancesoftware to aid trouble-shootingand data logging. An independentsensor communicates with the TA-SCOPE to deliver data quickly,thereby enabling contractors tobalance a system, troubleshoothydronic problems and log system performance.

Because data is captureddigitally, the TA-SCOPE can beconnected to a computer using a USB cable so that informationcan be uploaded to TA Select, the HVAC design software. Thismeans it is easy for consultantsand designers to determine themost economical system design,

the correct size valverequirements and pre-settingvalues. From here the user canprint reports taken directly fromthe system using the TA-SCOPE.

With a simple user interface, theTA-SCOPE is designed with theuser in mind. The intuitive icondisplay makes navigating the tools quick and easy. Low power

consumption and long battery lifemeans that one full charge of the unit provides three full days ofwireless performance, eliminatingthe risk of downtime during a sitesurvey or monitoring job. Thecompact size of the unit means it is easily transportable incomparison to other standard-size units, slipping easily into apocket while onsite.

Peter Rees, Technical Directorfor Tour & Andersson explains the importance of measuringwaterborne systems and the need to do this in an efficientmanner: “Without measuring,waterborne heating and coolingsystems can very quickly becomeless efficient as the flow, volume,pressure and temperatures shiftfrom the set point. This costs thebuilding owner or end user in bothenergy and carbon emissions,which could be avoided throughthe correct measuring andbalancing of the system. Bymeasuring and troubleshootingusing a device such as the newTA-SCOPE, a system can bemaintained as it was designed to operate – energy-efficiently and cost-effectively.”

It is difficult to imaginetoday's world without the useof copper – electrical energy,heating, air conditioning,plumbing, transport andcommunications are allimportant aspects of oureveryday lives which couldnot exist in the way that weknow it without the substantialuse of copper components.

Copper is especiallysignificant in respect ofbuilding services, particularlywith the emergence ofrenewables and thesustainable industry sectors.To that end Irish MetalIndustries (IMI) is Ireland’sleading copper supplier,offering a complete range of copper tube for hot and

cold water installationservices, sanitation, centralheating, air conditioning,medical gas and numerousother building andengineering applications.

IMI offers copper tube to IS EN1057 carrying the Irish Standard Mark, BSIKitemarked tube to BSEN1057, and an extensiverange of plastic-coated tube.The portfolio includes high-performance copper tubes,both bare and covered, which are ideal for anyplumbing and heatingapplication, as well as for the distribution of medicalgases in the healthcareindustry.

Copper tubes offer long life, strength and maximumcorrosion-resistance and thus meet all therequirements for trusted andsure plumbing and heatingsystems. Copper tubes havelong been considered idealfor all domestic applicationssuch as hot water, cold water,drinking water, heating, gas,distribution of combustiblefuels and drainage systems.This continues to be the case but copper is now alsoemerging as the product of choice for qualityrenewable/sustainablesystems such as geothermalenergy installations.

Copper is a natural and completely recyclableelement which has excellentproperties in the search foralternative energies, such asthose sources of energy thatencourage sustainable growth without damaging the environment.

“Because of the physical-mechanical properties of

copper”, says Conor Lennon,General Manager, IMI, “we are very observant ofrenewable energies andaware of the role that copperproducts can play in thedevelopment of new productsin this sector. Particularly inthe area of solar heatingsystems, IMI offers a range of specific products that are used as components insolar collectors”.

The same applies to air conditioning. The mainelements that make up an ac system require coppertubes to more effectivelyperform their function. Copper tubes areindispensable for thedistribution of liquids used in condensers andevaporators, which representthe main part of an ACRsystem. They are also usedfor connecting the variouselements in order to ensure a correct installation of the system. “The coreinherent properties, strengths and health benefits of copper for use in what is now referred to as building services havemade it the product of choicefor centuries“, says ConorLennon. “As the sector hasmatured and developed, sotoo has the use andapplication of copper. Now,with renewables andsustainability emerging as thedominant force in buildingservices, copper is onceagain proving itself the ideal solution.”

Although the majority ofairborne particulate emissionsare generated by road traffic,there is also a smallcontribution from biomassboilers. New air qualitylegislation, therefore, mayalso have an impact on thespecification of biomassboilers and associatedfiltration systems, says KevinStones, Engineering andService Director with Hoval.

EC Directive 2008/50/EC,Ambient Air Quality andCleaner Air for Europe, cameinto force on 11 June 2008

and must be transposed intonational legislation no laterthan June 2010. A key factoris that it seeks to create acontrol framework for particlesdown to a diameter of 2.5microns (PM2.5). In the past,emphasis has been onparticles with a diameter of 10 microns or above (PM10)and, crucially, the traditionalfilters used with biomassboilers (cyclones and multi-cyclones) are not able to filterparticles down to PM2.5.Consequently, we will soon be faced with a need for more

efficient, retrofittable filtrationof particulate emissions frombiomass boilers.

Size mattersThe level of emissions from a biomass boiler will vary withthe quality of the fuel andcombustion efficiency of theboiler. So, using boilers thatcomply with EN 303-5 Class3, in conjunction with highquality fuel, is the first step in minimising particulateemissions.

Many biomass installationsalready use a cyclone ormulti-cyclone but these aretotally dependent on the massof the particles removal so,while they remove around50% of coarser particles, they do not remove particlesbelow PM10.

An alternative is electrostaticprecipitation but electrostaticfilters tend to be expensiveand very large – often toolarge for typical plant rooms.

Until recently there has notbeen a financially-viablealternative but Hoval has nowoptimised a ceramic filter thatwas already in use inindustrial applications for usein biomass installations –without making the overall

cost of the installationprohibitive.

Capable of removing up to96% of PM2.5 and PM10

particles, ceramic filters canbe used with any type ofbiomass boiler and can beretrofitted to existinginstallations. They areconnected to the back of theboiler, in the same way as acyclone. Each unit contains amatrix of porous ceramic tubeswhich are closed at the lowerend. The number of tubes ineach matrix is aligned with fluegas volumes for each boiler.

As flue gases are drawnthrough the filter by an inlinefan, the gases are able topass through the walls of theceramic tubes, while particlesare trapped. At regularintervals (timed and/or inresponse to a pressure dropacross the filter) a pulse of air is used to dislodge theparticles, which fall into acollection bin.

Moving forwardThere is a very real concernthat failing to controlparticulate emissions couldseverely curtail the potentialfor biomass which, in turn,would have a significantimpact on the ability to reducecarbon emissions. Hoval CFfilters have the potential tomeet the challenge ofparticulate emissions andensure that biomass remainsas a viable element inIreland’s renewable heatingstrategy withoutcompromising on air quality.

Following the EUcommitment to reduce energyconsumption by 20% by2020, energy waste fromresidential space heating and domestic hot water have been identified as keyreduction targets. Air-to-water heat pumps areconsidered a major tool in this effort and are nowclassified as a renewableenergy technology.

It is against thisbackground that the newToshiba Estia air to waterheat pump range wasdeveloped. This is an all-in-one system designed todeliver the right temperaturefor space heating, fordomestic sanitary hot water,and with the additionaladvantage of offering airconditioning in the warmerseasons (assuming fan coils are used).

Toshiba air to water heatpump systems can managetwo independent zones,enabling the delivery of water to diverse emitters atdifferent temperature levelsup to 550C. This results ingreater energy savings whilethe use of the Toshiba high-efficiency heat pump offersthe additional bonus of long-term reliability.

Underpinning theperformance and lifespan of the system is Toshiba’sinverter technology which

incorporates the new vector-controlled, intelligent powerdrive unit which enables awider range of frequenciesand voltages. In addition, the Toshiba twin rotarycompressor has a widecapacity range with aneffective system of powerlimitation which reducespower consumption.Performance is furtherimproved by the high-speedinverter circuit whichcalculates and optimises the power supply to thecompressor.

With its best in class COP,the Toshiba Estia air to water

heat pump delivers moreheating power with lessenergy consumption, usinghigh-quality components and materials whichcontribute to overall savingsin energy consumption. With the Toshiba advancedinverter, the system onlydelivers the heating capacity required, thusconsuming only thenecessary electricity.

The hot water temperatureis also optimised dependingon external temperatures.During milder conditions the system automaticallyproduces lower watertemperatures, anticipatingreduced heating demandsinternally. The same controllogic allows it to anticipateheating needs when externaltemperatures drop. Thisoverall temperaturemanagement gives the best conditions of comfort.

Toshiba Estia heat pumps

can be used in combination

with different types of emitters

such as low-temperature

radiators, underfloor heating,

Changes in buildingregulations and a rise in the awareness of green orrenewable energy, combinedwith government initiatives on sustainability, have led to an increased acceptance of alternative methods ofhome heating.

“As often happens when a market opportunity like this occurs, there is aconcomitant explosion ofsuppliers” says PaulSchweppe of Core AC. “This is the case with the Irish heat pump market where there are now multiplebrands listed on the SEIGreener homes website.

“However, at times like this it is best to go withsomeone who has a proventrack record in this area ofexpertise, and thus avoidmistakes which can provecostly and damaging, both in terms of finance andreputation.

“Carrier is the number oneselling brand of chillers, notonly in Ireland but alsoworldwide. This position hasbeen achieved by providingan appropriately-costedproduct that meets the needsof specifiers and end-users, is both reliable and energyefficient, and is backed by aworld class service and after

sales organisation. “So what makes a Carrier

heat pump different? Firstly,from the specifier’s point ofview these heat pumpsrepresent very little risk. Aswith our chillers, our heatpumps can be provided ascomplete packaged systems– all pumps, UFH controls,interconnecting cables, safetydevices, etc are included.

“Secondly, Carrier heatpumps are designed to be installed by competenttradesmen ... requiring nospecialist training orunderstanding in heat pumptechnology. The bestcomparison we can make is that fitting one of thesesystems is no morecomplicated than fitting a wall hung boiler.

“Finally, our Carriersystems offer the highestlevel of comfort available on the market. From it’sinception 25 years ago, theNexa brand was always seen as delivering the highest level of residentialcomfort to the end-user.

“Nexa by Carrier usesstate-of-the-art technology in all its control systems.Rather than opt for the morecommon and cheaper on/offthermostatic type controls,Nexa chose to employresistive-type room sensorswhich have a high degree ofaccuracy and have combinedthese with proportionally-activated motorised valves.

“This type of system hasmore in common with thehigh-end buildingmanagement systems used inindustry than the conventionalheating system found in manycontemporary residences.

This fully automated weather-compensated control is thekey to the tight control thatCarrier can offer end users ofour systems”

Air Source or GroundSource?As a provider of both groundsource and air source Carrierheat pumps, Core Engineersare well qualified to consultand advise on each particularapplication, and to thenrecommend the mostappropriate solution for thatproject. Generally speaking,only if the ambienttemperature drops below -100C for 10 consecutive days would Core recommenda ground source system.

“Carrier air to water heatpumps are particularly suited to our climate”, says AustinMcDermott, ManagingDirector of Core AC.

“Unlike units designed for use in areas such asScandinavia or CentralEurope, they can handle high humidity conditions with ease. The defrost cycle,often seen as a limiting factorwith air to water heat pumps,is handled with ease. Acombination of smart controlsthat measure and compareambient and evaporatingtemperatures and compressorrunning pressures allowsCarrier to optimise energyusage on the defrost cyclewhile the ‘tall and thin’ profileof the outdoor coil reducesthe potential for ice to form in the first place.”

Heat pump and heatrecovery technologies arealready well known in buildingservices with a proven trackrecord for high efficiencies in respect of heating andcooling. Mitsubishi Electrichas now harnessed therespective strengths of bothtechnologies and incorporatedthem into the new City MultiAir to Water (ATW) Series toprovide hot water.

Compared to conventionalboiler systems, ATW offers

infinite design flexibility,excellent energy efficiencyand reduced CO2 emissions.There is also a significantreduction in capital costs as ATW provides hot water by means of electricity,thereby eliminating the need for a separate gasinstallation.

City Multi outdoor units –both air-cooled heat pump/heat recovery or water-cooledheat pump/heat recovery –can be connected to the ATW

system depending on thesystem structure.

This new highly-advancedCity Multi ATW system isavailable in a choice of twotypes of unit — a booster unitand a HEX (heat exchanger)unit. The booster unitprovides hot water to amaximum of 70oC and theHEX unit 45oC in heating anddown to 8oC in cooling. Bothare suitable for homes,offices, restaurants or hotels and provide the perfectindoor environment whilereducing running costs andharmful emissions.

Booster UnitBenefiting from the heatrecovery operation of the CityMulti R2 system, the boosterunit converts energy from theair to higher temperaturessuitable for supplying hotwater and results in virtuallyno energy waste. This unit isbest suited to applicationssuch as sanitary water,showers, etc. The boosterunit is connected to a BCcontroller with refrigerantpipes, and to the water tankwith water pipes. The wasteheat from the coolingoperation is used for heatingto provide hot water.

HEX UnitMeanwhile, by utilising waste heat from the City MultiR2 outdoor unit for heatingoperation in the HEX unit, it ispossible to supply hot waterwith high efficiency. Also,even when connected to theCity Multi Y series, it providesefficient operation comparedto a conventional system.

The HEX unit is best suitedto underfloor heating, panel

heating, and fan coil unit(AHU) applications. As withthe booster unit, it isconnected to a BC controllerwith refrigerant pipes, and tothe water tank with waterpipes. However, it is notequipped with a compressor.

EcodanAlso available from Mitsubishi Electric is the Ecodan air source heat pump which consists of anexternal packaged systemwith a built-in waterexchanger which is plumbedin like a conventional oil/gasboiler unit.

It harvests renewable, low-grade energy from theoutdoor air and upgrades thisinto useful heat to supply ahome with hot water andheating. For every 1kW ofelectricity fed into Ecodan, atleast 3kW of heating energyis returned. It can workefficiently all year round, evenif the outdoor temperatureshould drop to -15oC.Installation costs vary fromproperty to property but, as a guide, costs are similar to that of a conventional gas boiler.

From data provided byBRE testing (the UK's leading centre forindependent advice for the built environment), and from case study analysis, running costs can be reduced over aconventional gas boiler by approximately 35%, using standard tariffelectricity.

Kinviro Directors Frank Daly and Alan Callister.

Directors Frank Daly and Alan Callister are both highly-qualified engineers and, what sets Kinviro apart from otherindustry players, is the application of their combinedstrengths and experience to assist specifiers and installerswhen providing high-performing, cost-effective, energy-efficient heating and hot water solutions.

With the introduction of the Energy Performance of Buildings Directive (EPBD) and the subsequentenforcement of BER certification – coupled with risingenergy costs – specifiers and clients alike are now moreconscious than ever of the need for genuinely-sustainableheating systems.

Serving the heating and hot water requirements of large,mixed-use developments and apartment complexesrequires an innovative approach, especially in order to meetthe energy performance criteria of new building regulations.Centralised energy generation with a renewable or efficientenergy input, coupled with accurate metering, is the answer.

Such district/community heating schemes are cost-effective to install, easy to manage, eradicate the need forseparate water storage in individual apartments, and doaway with the need for costly maintenance of individualboilers.

Kinviro has been, and still is, involved in a number of suchprojects. Domosolutions from Watts Industries are meteringsystems specifically designed for centralised energysources, while inclusion of SenerTec’s micro CHP, theDachs, in the central energy centre is a cost-effectivemethod of meeting building energy targets.

While the quality characteristics of the respective productranges are long-established and field-proven, critical to theperformance of the turnkey solutions devised by Kinviro isthe engineering input of Frank and Alan. They provideproject consultation, design assistance, technical support,installation guidance and commissioning advice, workingclosely with the consulting engineer and contractor toensure optimum system efficiencies and energy savings.

Most households are aware they will save energyby turning off lights andappliances when not needed,but each accounts for amaximum of only 3% ofdomestic heating consumption.UK Government figures show84% is for heating and hotwater, and the figures forIreland are said to be similar.

Significant energy savings

can be made for a modestoutlay by upgrading existingheating controls, or installingenergy-saving controls for thefirst time in those homeswhich lack basic controls,such as a room thermostat.When a boiler is replaced, it is

essential to upgrade thecontrols so it can workenergy-efficiently.

Installers must stress tohouseholders that the newcontrols – which will cut theirfuel consumption – will alsomake their homes morecomfortable.

Wireless heating controlsare now well establishedbecause of the huge time-

savings they make oninstallation time and hassle.There are no control cables torun, there is no untidy wiringand no damage to homedecorations. New wireless-enabled heating control packs are now available

which make it even easier forinstallers to install energy-efficient control. HoneywellSundial RF2 packs include wireless-enabled timers and wirelessthermostats which worktogether automatically, so are even quicker and simplerto install than standardwireless controls.

The wireless thermostatcan be wall mounted using its wall bracket, or placed ona table-top using the baseprovided.

Three pack types areavailable to match the needs of different types ofheating systems. Each packcomprises a wireless-enabledtimer, wireless roomthermostat, and (in Pack 3) a wireless cylinder sensor.

Crucially, they are designedto be easy to use byhouseholders of all ages, and they use the latest control technologies. They feature TPI (TimeProportional and Integral)advanced energy savingcontrol, which increasesboiler efficiency by adjustingfiring duration with demand,

while the thermostatsmaintain room temperaturesvery closely to the set point – an advantage over all other domestic roomthermostats using simpleon/off control.

They also include“Optimum Start” whereby the user sets the time whenthe desired temperatureshould be reached, not thetime the heating starts. Thecontroller senses theprevailing temperature andsaves fuel by delaying thetime the boiler fires until thelatest possible moment thatwill still achieve the settemperature by the time it is needed.

In summary, a heatingsystem is only as efficient as its controls. It is now easy and very cost-effectiveto install energy-savingcontrols as a “first fit”, or toreplace existing controls,using Honeywell Sundial RF2 packs which link together wirelessly.

Daikin continues to makesignificant inroads into theheating sector in Ireland,mirroring a similar pattern in Europe following theintroduction of the highly-advanced Altherma LT split air to water heat pump.

Daikin Altherma is a totaldomestic heating and hotwater system based on airsource heat pump technology.It represents a flexible andcost-effective alternative to afossil fuel boiler, with a

cooling option. The inherent energy efficiencycharacteristics of DaikinAltherma make it an idealsolution to reduce energyconsumption and CO2emissions.

The seasonal factorperformance of the DaikinAltherma heat pump is also largely attributable tothe Daikin inverter principle.An integrated frequency-convertor adjusts therotational speed of thecompressor to suit theheating demand. Therefore,the system seldom operatesat full capacity so the end-user pays only for the energy actually needed.

Daikin Altherma uses a

natural source of energy. The outdoor unit extracts heat from the outside air and raises its temperature to a level high enough tosupply heating. This heat isthen transferred to the indoor

unit through refrigerant pipes.The compact outdoor unit iseasily installed and, as nodrilling or excavation work isrequired, it can also be easilyinstalled in flats andapartments.

The heart of the DaikinAltherma system is the indoor unit. It heats the waterthat circulates through lowtemperature radiators, floorheating systems or fan coilunits and also providesdomestic hot water. If thecombination heating andcooling option is specified,then the indoor unit can alsodecrease the watertemperature to distribute a refreshing coolness

Market reaction to theAltherma LT was very positive from the outset and Daikin responded tospecifier and user feedbackby developing the Monoblocversion to cater forapplications requiring amodular system. Both theseLT solutions were ideallysuited to the new-build marketwhere the heat emitters were based on low-temperature output.

However, it soon becameapparent that a high-temperature model wasrequired, especially for theretrofit sector, and so the HTversion – which can achievetemperatures of up to 80oC –was introduced.

This particular version hasnow been further developedto provide the perfect solutionfor the very specificrequirements of apartments.One outdoor unit linked tomultiple indoor units candeliver reduced running costsof as much as 33%, while

carbon emissions can bereduced by as much as 66%.It will be available from June2010 onwards.

Solar panelsOn top of this major step intothe commercial heatingsector, Daikin has alsoexpanded its heating rangewith the acquisition of RotexGmbH and the introduction of its extensive solar range.Appliations include bothprofessional and drain-backoptions. Founded in Germanyin 1973, Rotex now employsmore than 360 employees,boasts its own developmentdepartment, and exports to 21countries. It is a wholly-ownedsubsidiary of Daikin EuropeNV since 2008.

Daikin is now also a fully-fledged heating companywith an extensive range ofmarket-leading renewabletechnologies and productsthat cater for for the domestic and commercialsectors, from new-build toretrofit.

The recent one-day CIBSEconference on sustainablerefurbishment in the beautifully-

refurbished Clontarf Castle in Dublin was a great opportunity to meet some of theindustry’s leaders and gauge the direction of the Irish construction industry. It was animportant and timely event and a credit to the team of CIBSE volunteers that pull it alltogether. A number of speakers predicted that Irish construction would be dominated byinfrastructural and refurbishment projects foryears to come and, as Professor Converynoted, for the first time refurbishment projectshave parity of esteem with new build.

The keynote address was delivered byMinister Eamon Ryan who pointed out that a national focus on refurbishment was apositive development. Much of Ireland’sbuilding stock is over 20 years old and poorlybuilt. There is also a large stock of historicbuildings in need of refurbishment. TheMinister noted that we could not “cut” our way out of recession and that refurbishmentprovided the opportunity to stimulate theeconomy while reducing our dependence on fossil fuels. Several speakers reinforcedthe Ministers comments and provided datademonstrating how the most cost-effectiveenergy savings would be generated byraising the efficiency of older buildings.

The Minister sees government’s role askick-starting the industry and helping theestablishment of a supply chain. This is beingachieved by establishing a range of schemeson a “smaller” trial basis. The schemes thatdeliver results will be expanded and deployedwidely. He also suggested that the currentgrant support mechanisms were notfinancially sustainable and ultimately Irelandwill move towards a more stable obligationscheme which encourages energy producersto reduce demand. This model has been

deployed successfully elsewhere.There was broad agreement that weshould continue to look at bestpractice in other jurisdictions anddeploy those solutions in Ireland.

Paula Butler outlined how SEIwould be busy in 2010 spending e130 million on insulation programsand on energy improvements to thegovernment building stock. The plan is to improve the performance of over6,000 homes and hundreds of non-domestic buildings. This is aimed atsupporting 5,000 jobs and generatingover e400 million in savings. SEI willalso focus on the generation of newtechnical standards and codes ofpractice to guide the industry (againlooking at best practice overseas). In the longer term (2011-2012) thewide range of grant supports that exist would be integrated into a single retrofit program.

Dr Kevin Kelly from DIT discussedthe need for the industry to develop a culture of research: “times havechanged and it is no longersatisfactory to continue business asusual.” He encouraged companies toengage with higher education and todevelop new ways of doing things:companies needed to becomelearning organisations. This messagewas reinforced by Professor Converywho emphasised that we must learnfrom the mistakes of our recent pastand not simply replace one bubble(new housing) with another(refurbishment.) It will take only five to 10 years to refurbish most of ourbuilding stock, and it is therefore vital that we create technology andsystems that last past this build phase.We need to build an export businessin the refurbishment space.

The issue of measurement cameup time and time again, not only fromthe speakers but also from the floor –what gets measured gets improvedwas the mantra. One delegate askedhow we ensure that jobs such as theinstallation of insulation were donecorrectly. Oversight was proposed as one solution. However, while much has been achieved by means of regulation, the level of oversightwas considered poor. Indeed, thereseemed to be broad agreement that we need a greater focus onenforcement and not simply regulation.

I believe that we could apply theminister’s model of looking to otherjurisdictions such as the United Statesfor models to address this particularproblem.

While energy certainly received thebulk of the attention, it was good tosee the subject of water being raisedby a number of speakers. Indeed,when it was raised, the impression left was that the provision of waterservices should be on par with thoseof energy.

Professor Tim Dwyer and Neils Ulrik brought an internationalperspective to the conference. Tim used his recent attendance at an ASHRAE meeting in Florida as aback-drop and reflected on what ishappening in the United States. Neils reviewed a number of projects inDenmark and the issues that had arisen there. It was striking thesimilarities in terms of aims, initiativesand progress: if we get this right thereappears to be an export market for the know-how.

Liam Connellan from Dalkiapresented a paper that discussedfinancial models that could be used bythe private sector to fund energyinitiatives and described how


As is now established practice, bs news invites one of the keynote speakers at the CIBSEConference to write a synopsis of the day’s events.

teamwork was a vital element to projectsuccess. His paper was followed byseveral excellent case studiespresented by Paul Houston of PM group,Jim Murphy of HES Estates and JimO’Sullivan from the OPW. It would behard to do these presentations justice in a few short lines and I would

recommend that you look over theirpresentations on the CIBSE website.

Topics covered range fromestimation of residual life of installedequipment to working on restricted sitesand raising the energy performance ofbuildings such as the Customs Housein Dublin to that of a B Rating. There

was also an excellent review of relevantliterature by Anastasia Moylona ofCIBSE, with multiple links to knowledgesources.

As someone that has spent much ofthe last 20 years abroad, it is clear thatIreland has come a long way in thattime — there is a large cohort ofmotivated workers with the requiredknowledge, experience and training forthe jobs of the future. The mood of theconference was quite positive which,given the rollercoaster ride that theindustry has taken us on in the last fewyears, was great to see. People werehunting opportunities to growth sectors.

The impression I was left with wasthat there is money available for low-risk projects with a reasonable yield: itis a good time to get work done onhomes, hospitals, schools and offices. Ifwe move quickly, there is an opportunityto develop an export business, toleverage the available underutilisedtalent. The time for refurbishment isnow. �

Irish Young LighterThe Irish Young Lighter competition began

in DIT in 2003 when the first students on the

programme in Electrical Services Engineering

graduated. Ken Winters was the inaugural overall

winner and he then went on to represent Ireland at the

international Young Lighter in London in 2004, where he won

the Best Presentation. In the intervening years many others

have followed in Ken’s footsteps and proudly represented

Ireland at this annual event.

Last year SLL announced that entry to the Young

Lighter competition for 2011 would require the Irish entrant to

come through an Irish heat and the 2010 Irish Young Lighter

competition now represents this heat. The competition is

open to any Irish designer/engineer aged

30 years of age or less.

Kerr steps down after 10 years at helm


Seamus Kerr, director RSL Ireland and outgoing Chairman of RefrigerationSkillnet, looks back over his 10-year tenure in the driving seat and reviewsthe issues tackled and goals achieved. Established in 1999 in response to aGovernment-led initiative, Refrigeration Skillnet is made up of refrigerationand air conditioning member companies who participate in training,seminars and professional development programmes.

Despite being a newly-formedcompany run by a small group of volunteers, Refrigeration Skillnet

was successful in winning funding toorganise enterprise-led training for therefrigeration industry. Since then, it hassubmitted proposals for each round offunding and has been successful eachtime. Ten years on and RefrigerationSkillnet is still going strong, making it one of the longest-running of all theSkillnet networks in Ireland.

Refrigeration in all its forms plays a vital role in industry, especially in Ireland,which has significant manufacturing and food producing facilities locatedthroughout the country. Refrigeration is a big energy user with some sources

suggesting that 15-20% of all electricalpower produced in Ireland is used byrefrigeration, chilling or air conditioningequipment, from huge industrial plants tothe domestic fridge at home. Imagine thecarbon emission reduction if we couldimprove the efficiency by 10%, or maybeeven 20%. Refrigeration also has thepotential to have a significantenvironmental impact and one of ourprimary goals has always been theminimisation of that impact.

Ten years ago the refrigeration industry in Ireland was facing numerouschallenges. These included newregulations and legislation as part of theimplementation of the Montreal Protocol;new technologies; demand for alternativerefrigerants driven by environmentalconcerns; skills shortages; and increasedcompetition from other European serviceproviders. Despite this, the refrigerationindustry had no representative body andthere was practically no training availablein Ireland for the upskilling of refrigerationservice engineers.

Consequently, Refrigeration Skillnetmoved quickly to identify the trainingneeds of both members and the industryat large. One particularly successfulcourse was the refrigerant handlingcourse, C&G2078, which was run before it was required by the ODS regulations.This was an early example of “stayingahead of the curve”, a philosophy whichcontinues to this day as is evidenced bythe newly-developed C&G2079 training

and certification programme. While the main focus of

Refrigeration Skillnet was – and still is – training, professionaldevelopment and upskilling, as timeprogressed it saw the need for a

representative organisation with a widerremit. Hence the Institute of RefrigerationIreland (IRI) was established with theobjective of representing the industry,improving standards throughout theindustry, and awarding membership tosuitably-qualified candidates. So, 100years after ASHRAE was established,Ireland finally had a body representing the refrigeration industry.

The IRI very quickly joined AREA –the European refrigeration contractor’srepresentative body – as up to this point,Ireland was one of only two Europeanmember states not represented. The IRIplayed an important part that first yearwhen the European Parliament voted onthe total banning of HFC and HCFCrefrigerants. Thankfully the motion did not pass.

“Some people make things happen,some watch things happen, while others wonder what has happened”, says Seamus Kerr. “In both RefrigerationSkillnet and the IRI, we don’t just watchand wonder what has happened, we get involved and make things happen.During the past 10 years we havewitnessed huge changes in therefrigeration industry, and we havechanged to meet the challenges.

“Ten years on and I am glad to say that Refrigeration Skillnet is in a healthyposition with an experienced andcommitted board. This now allows me theopportunity to step down as Chairman,though I will remain on the board with theother volunteer members. I am delightedthat John Sampson, Danfoss Ireland, hasagreed take on the role of Chairman and I look forward to supporting him as westrive to further the interests of theindustry over the coming years.” �30

Core Air Conditioning has

represented Emerson in Ireland

for 13 years, during which time it

has gained considerable market share

for the Liebert air conditioning range.

More recently, it has added the Knurr

range of network and server racks, and

rack-cooling solutions, to its portfolio.

“Emerson Network Power has always

prided itself in supplying its customers

with industry-leading products and

solutions in terms of quality, performance,

service and overall value-for-money

throughout the life of the equipment”,

says Brian Hall, Regional Manager

Ireland, Liebert Power & Cooling

Products.

“In Ireland, we are pleased to have

had a long relationship with Core Air

Conditioning who are authorised to

supply, install, commission and maintain

our range of Liebert air conditioning

products and solutions. This includes

chillers, room cooling units,

high-density cooling

solutions, etc.

“Core has had

considerable

success with

Liebert and we

anticipate similar

market inroads

being made

with Knurr, the latest Emerson addition to

the Core portfolio.

“To ensure that our products operate to

peak efficiency, give maximum reliability

and prolong their life, they should be

installed, commissioned and maintained

by factory-trained engineers. All of Core’s

close-control engineers have undergone

specialist training at the Emerson facility

and fully understand our control systems.

They also have access to the latest

hardware, firmware and software releases.

“We also provide a 12-month warranty

on units, provided they are

commissioned at first start-up by Core’s

engineers. This way we can determine

that the units are correctly installed, that

the correct installation procedures have

been followed, and that the units are not

operating outside normal design

conditions. Failure to meet these criteria

can void the warranty.”

Not surprisingly, the same quality of

service coupled with quality products

underpins the Core trading philosophy.

Since he established the company in

1996, Managing Director Austin

McDermott has operated a very

disciplined and structured management

system. The product portfolio comprises

only market-leading brands of renown,

while the service support is ultra-

professional.

“Core Air Conditiuoning is all about

partnerships”, says Austin, “the

partnership between management and

installers; the partnership with clients;

and the partnership with suppliers.

Effectively, we see ourselves as the

conduit through which the client’s needs

are matched with the appropriate

suppliers products to provide the most

cost-effective, energy-efficient,

sustainable solution.

“Emerson is the ideal partner in this

respect. Apart from an excellent product

range, their support allows us offer a full

range of maintenance contracts which

cover all critical power and cooling

systems, including generators, UPS

systems, static transfer switches, chillers

and room cooling units. Contracts can be

tailored to meet individual requirements

in terms of equipment, response time,

frequency of preventative maintenance

visits, etc.

“Over the past 13 years Emerson

Network Power and Core Air

Conditioning have developed a trading

partnership which has benefitted both us,

our installer network, and clients, in

equal measure. It is this mutually-

beneficial relationship which lies at the

heart of our collective success to date,

and which will undoubtedly secure further

growth and prosperity into the future.”

The emergence of the EU meant a harmonisation and integration ofnumerous technical standards,including EN 62305, which originatedfrom a European Norm standarddeveloped by the IEC and adopted by CENELEC. The new standard, EN 62305, took over 20 years to write and had input from hundreds oflightning protection specialists fromthe 28 different member countries that represent CENELEC, including Ireland. The standard was published in Ireland by the NSAI as IS EN 62305.

The approach to the new standard is much broader and more complex than the withdrawn BS 6651. However, it is resulting in an industry-wide collectiveimprovement in the level of protection against the detrimentaleffects of lightning which can lead toinjury and financial consequencesfrom interruptions to businessoperations.

Summary of IS EN 6230IS EN 62305 consists of four parts as follows

Part 1: General principlesThis is primarily an introduction to allother parts of the standard andoutlines the general principles ofprotection against lightning and howan effective system can be designedutilising these principles.

Part 2: Risk managementThis outlines the methodologyrequired to determine if lightningprotection is necessary for a buildingand includes a comprehensive anddetailed risk assessment whichdivides the primary risks that abuilding can experience into thefollowing four areas:• R1 – Risk of loss of human life • R2 – Risk of loss of service to

the public• R3 – Risk of loss of cultural

heritage• R4 – Risk of loss of economic

value

Designing Building ServicesThe introduction of the

new lightning protection

standard IS EN 62305

in 2006 superseded BS

6651 which had been

in use for the previous

21 years. The new

standard incorporates

significant change and,

being over four times

the volume of its

predecessor, posed a

considerable learning

curve for the entire

electrical services

industry.

Designing BS:Layout 1 23/03/2010 09:57 Page 1

In the evaluation process thedesigner identifies the applicablerisks of loss R1- R4, and the applicable tolerable risk (RT) for thebuilding. A comparison of these risks will determine the necessarylevel of protection. The magnitude of the required lightning protectionsystem (LPS) is dependent on how much R1- R4 exceeds RT.Alternatively, if the value of R1- R4

is less than RT, then no protectionmeasures are deemed necessary.

Part 3: Physical damage tostructures and life hazardThis generally describes how todesign an LPS and identifies the fourseparate classifications of protectionfor an external structure and provides many standard installation details and arrangements.

Various different techniques forestablishing how a structure’s airtermination system (air rods, tape orcatenary wire) should be installedsuch as the rolling sphere, protectiveangle and mesh method is alsodescribed in detail. Equipotentialbonding, earthing arrangements andthe use of naturally conductivebuilding materials as part of the LPSare also assessed. A number of different annexes are included with an important one in particularrelating to system maintenance,inspections and testing.

Part 4: Electrical and ElectronicSystems within StructuresThis final part is wholly devoted to the design of a LightningElectromagnetic Impulse ProtectionMeasure System (LPMS) which is ameans of protecting the internalelectrical and electronic buildingservices from the effects of aLightning Electromagnetic Impulse.

An LPMS can be achieved by thestrategic implementation of earthing and bonding,electromagnetic shielding and the co-ordinated positioning of surgeprotection devices (SPDs).

The concept of distinct lightningprotection zones (LPZ) for a buildingis introduced and the various criteriafor selecting SPDs are reviewed.

Principal differences between BS 6651 and IS EN 62305.Although there are a considerablenumber of differences between bothstandards, a summary of three of thekey items that will impact designengineers most are outlined here:

Risk assessment processAn in-depth risk assessmentcalculation is mandatory for all new buildings to determine what level of lightning protection, if any, is required. The risk assessmentprocess in IS EN 62305 issignificantly more detailed with over a hundred pages attributed to it in comparison to nine pages in BS 6651.

In BS 6651 the risk assessmentevaluated the probability of the

structure being hit by lightningwhereas IS EN 62305 is muchbroader and assesses the individualrisks to the loss of human life, public services, cultural heritage and economic value as outlined inFigure 1 (above) which highlights thetypes of loss and corresponding risksresulting from different types ofdamage.

Loss of human life is the mostimperative factor for obvious reasons.Loss of public services relates to theimpacts that damage to municipalservice providers such as hospitals,government agencies, educationalinstitutions etc would have on thepublic. Loss of cultural heritagerelates to the risk of damage to ahistoric monument or building ofethnic importance. Loss of economicvalue relates to the financial impactthat a strike could potentially have on a structure or business and willrequire input from the buildingoccupier.

This assessment, with manydifferent parameters, can be veryrepetitive and time-consuming whencompleted in long-hand format.Although various commercialsoftware programmes are available

to aid with this calculation, careneeds to be taken as certain versionsutilise different parameter indices setby the national standards of otherEuropean countries. For example, the British edition of the standard, BS EN 62305, currently uses different risk assessment parametersto the Irish version IS EN 62305 inrelation to the tolerable risk of loss of service to the public and loss ofcultural heritage.

LPS classificationBS 6651 specified only two differentclasses of protection against theeffects of lightning whereas IS EN62305 now specifies four classes asshown in Table 1.

The selected class of protection isdependent on the result of the riskassessment calculation and theprotection class implemented will alsodetermine how regularly the LPS willrequire maintenance inspections.

LEMP Protection Measures System(LPMS)The most fundamental change in IS EN 62305 is the inclusion of anLPMS as an integral part of theoverall LPS to protect against theeffects of lightning surges. Althoughsurge protection was an importantpart of other international standards,it was only published as aninformative annex addendum to BS 6651 in 1992 as an optionalrequirement and therefore was notalways incorporated into the designof most protection systems.

We now live in a truly electronicage where it is more essential thatelectronic and IT systems areadequately protected from theharmful and interfering effects oftransient surge currents and the newstandard duly recognises this.

IS EN 62305 designates the surgeprotection of the internal electronicand IT systems to be as importantas the protection of the externalstructure. An evaluation of thecomplete building is now requiredwhen assessing the need for an LPSand must include both the externalstructure and internal services withneither being looked at in isolation.

Even an indirect lightning strikehundreds of meters away from a

building can potentially lead totransient surge currents and voltagesbeing induced, by resistive orinductive coupling, into the power andcommunications cabling entering thebuilding. This can have disastrouseffects on the internal electronicsystems that are relied upon for thecontinuity of business operation andtherefore it is prudent to reduce thisrisk with the co-ordinated positioningof SPDs throughout the facility.

IS EN 62305 segregates theprotected building into four lightningprotection zones (LPZ) comprisingtwo external and two internal zoneswith each zone having a reducedexposure to the effects of lightningimpulses as defined below;

• LPZOA : An external zone wherethere is threat of a direct lightningstrike and a full LEMP discharge. This

area would generally be the roof ofthe structure.

• LPZOB : An external zoneprotected against a direct lightningstrike although a threat still existsas the full LEMP discharge couldoccur within its vicinity. This areawould generally comprise thestructure’s perimeter walls.

• LPZ1 : An internal zone protectedfrom direct lightning strikes andwhere the surge current is reducedby the use of SPDs at the buildingboundary. This area wouldgenerally incorporate the primaryutility services entering thestructure.

• LPZ2 : An internal zone locateddeeper within the structure whereany surge impulse is further limitedby the use of supplementary SPDsand spatial shielding. This areawould be the most protected partof the building and could compriseof a fully screened control room or comms room.

Generally, the higher the LPZ ratingthe more secure it will be against theelectromagnetic effects of the strikeand therefore any sensitive electronicequipment should be situated inhigher ranked zones. As aconsequence, rooms containingsensitive equipment should not be located on top floors or nearexternal perimeter walls.

An example of a complete LPMSfor a typical building indicating eachLPZ, the positioning of SPDs anditems requiring bonding is illustratedin Figure 2 (opposite).

Given the various categories ofzoning and the different types ofelectrical and electronic systems tobe protected, it is important that a co-ordinated approach is taken to theselection and installation of a seriesof SPDs throughout the building.SPDs may need to be installed in acascaded manner to ensure that theLEMP is reduced to a negligible level

as it passes through the variouszones. Primary service entry devicesprotect against sparking/flashoverand will nullify the surge current as itenters the building although furtherdownstream SPDs may be requiredto eliminate any latent let throughtransient over-voltages.

Industry impacts and conclusionCompliance with IS EN 62305 will lead to increased financialimplications on building servicesprojects in terms of the following:

• Increased design hours (complexityof risk assessment process andimplementation of LPMS);

• Increased installation costs(additional materials due to higherLPS protection classifications andrequirement of SPDs);

• Increased maintenance costs(inclusion of SPDs).

Buildings containing explosiveenvironments will now requiremaintenance inspections every sixmonths instead of annually, whichwas the case in BS 6651 and this willadd to the facilities life cycle cost.

It is also clear that lightningprotection now requires much moreconsideration and attention at theinitial design stage of a project wheregreater co-ordination with otherdisciplines such as architectural andcivil/structural will be necessary. Morecareful consideration will need to begiven regarding the final positioningof rooms within the buildingcontaining critical electronicequipment and, where possible, they should not be sited nearpotential lightning current routes.

Following last month’s articleconcerning the 4th Edition of theNational Wiring Rules (ET101:2008)and the role of the Electro-TechnicalCouncil of Ireland (ETCI) in thecompilation of this new mandatorynational standard, this article elaboratesfurther on the major changes cominginto effect. Key points to be covered are:

– Wiring Systems – Switchgear and Accessories,– Overcurrent Protection,– Overvoltage Protection

Wiring SystemsThe main changes are contained withinChapters 51 and Chapter 52. Section

514 Identification and marking containsthe internationally-agreed colour codesfor cables, outside of control wiringsystems. The stipulation of line coloursis to ensure that the electrical contractorinvolved with wiring an installation willbe alerted to voltages in excess of 400V.In relation to the colours associated withwiring:

• The line conductors over thethree phases (L1, L2 and L3) are brown, black and greyrespectively;

For installations where there is athree-phase distribution boardinto single phase, the colour ofthe line conductor from whichthe 230V is derived can beemployed;

For cables having lineconductors with cross-sectionalareas in excess of 120mm2, thesame colour can be employedover each line conductor.

• The colour blue can only be usedfor the neutral conductor;

• Sleeving of cables is notpermitted for any conductors upto 120mm2;

• Conductors having insulationcolour green/yellow may only beused for earthing and bondingconductors;

• The Protective Earth Neutral(PEN) in Ireland should be blue incolour with green/yellow markingat each termination.

Section 522 outlines the guidelines forthe selection and erection of wiringsystems in relation to externalinfluences such as danger due to thepresence of corrosive or pollutingsubstances

(Section 522.5), potential for impact

(Section 522.6) and other mechanicalstresses (522.8).

The methods for protection againstharmful substances include enclosingwiring in conduit or trunking (PVCconduit being acceptable) or byemploying wiring systems made ofmaterials resistant to the harmfulmaterials/substances present.

Protection against impact where therisk of mechanical damage to wiringconcealed in solid walls or in hollowwalls or partitions – e.g. penetration bydrills or nails from front or rear of wall orpartition – now has specific referenceswithin the national wiring rules. Methodsof protection include specific mechanicalcharacteristics of the wiring system orby the recognition of wiring systemsbeing installed in areas of reduced risk.

These conditions apply to areaswithin 150mm horizontal distance fromthe room corners, 150mm verticaldistance from the ceiling, and there mustbe clearance between wiring runs andthe reverse side of the wall of not lessthan 50mm. Wiring systems must beemployed as straight horizontal or verticalruns going directly to an accessory,appliance or distribution board

In relation to wiring systems employedin areas containing metal studdedpartitions, wiring passing throughopenings must have protection againstmechanical damage by means ofconduits, sheaths, grommets or bushingsand it is important to note that extraneousconductive metal parts must be bondedto nearest protective conductor.

Switchgear and AccessoriesThe Department of the Environment(DOE) has specified mounting heightrequirements in Technical GuidanceDocument M of the BuildingRegulations. These new requirementsrelate to socket outlets, lightingswitches, control devices anddistribution boards. Section 530provides the details pertaining to thisequipment and respective mountingheights. The specific details aresummarised in Figure 2.

The rationale for the specification ofmounting heights is to provide thecontractor a position where (s)he canadvise a customer on the limitations forpositioning of equipment.

Socket outlets are to be mounted at aheight of 400mm to 1200mm abovefinished floor level. These requirementsare not applicable to proprietary socketsystems for mounting in the floor,pedestals or skirting trunking incommercial premises, sockets outletsfor fixed equipment (e.g. luminaires) anddedicated socket outlets for applianceswhich are not normally accessible suchas cooker hoods or washing machines.

Wall switches (excluding controldevices such as thermostats) are to bemounted between 400mm and 1200mmabove floor level for domestic premisesand between 900mm and 1200mm forcommercial installations.

Distribution boards (DB) and/orconsumer units must be readilyaccessible and mounted so that the topof the Distribution Board (DB) must notbe higher than 2.25 metres from the

floor and the bottom of the DB to be not less than 1.4 metres from floor.Mounting of a DB lower than theminimum height is permitted forinstallations where, for example, theoccupant is disabled. For suchinstallations, access is limited so thatonly authorised persons may gainaccess and this would normally be by lock and key.

Another new consideration presentedin the National Rules concerns isolationof inaccessible socket outlets (554.3.5).This only applies to socket outlets thatare not readily accessible, e.g. under akitchen work-top or behind an appliance.There is now a requirement for a clearly-labelled isolation switch to be mountednearby. This means of isolation willprevent persons, for example,attempting to disconnect a washingmachine after it leaks while positionedon their knees in a pool of water.

Overcurrent ProtectionThere are two major changes introducedin these National Rules. The firstconcerns the potential for harmoniccurrents (Sections 523 and 524) –derived from non-linear devices such asIT equipment and banks of fluorescentluminaires – manifesting on the neutralconductor. The result is such that thecross-sectional area of the neutralconductor needs to be increased tosafely accommodate the resultinggreater current magnitude. Indeed, the implication of increased levels ofharmonics is that cables will be sized in terms of the neutral conductor asopposed to the standard approachwhere design current of the load isemployed.

The second change concerns themeter tails of installations (533.3.5): theelectrical contractor now has the optionof locating an installation’s main over-current protective device within the(outside) meter enclosure. If this optionis utilised, there are a number ofconditions that must be adhered to:

(i) The over-current protective devicemust be an MCB with a minimum 9kA breaking capacity provided themaximum import capacity (MIC) isnot greater than 50kVA;

(ii) The over-current protective devicemust be enclosed in a weather-proof enclosure of IP 55 minimumand comprised of non-conductingself-extinguishing material (750oC);

(iii) The enclosure must be fitted witha hinged, transparent cover forthe operation of the MCB whichmaintains the IP55 rating.

Over-Voltage ProtectionSection 443 outlines the means ofprotection against over-voltages;lightning is not as prevalent in Ireland asit is in mainland Europe and switchingsurges in modern electrical installationsare more responsible for over-voltagesproblems and are more generallyderived within the installation as opposedto being important from the networkprovision of protective over-voltagecontrol based on risk assessment andconsequences for:

1. Human life – safety services,medical equipment;

2. Loss of service in IT centres,public buildings;

3. Commercial consequences.There are four categories of impulse

withstand voltages (over-voltages)defined for electrical equipment, rangingfrom 1.5kV (Category 4) for equipmentsuch as computers and media devices,up to 6kV (Category 1) for equipmentnear the origin of supply such asmetering. �The views expressed in this documentrepresent a personal opinion and should not in any way be construed as a definitiveinterpretation of ET101:2008 or indeed of the ETCI itself.

Hindsight is a wonderful thing though, and even

though we are currently experiencing the pains of

recession, we are still far better off than so many

generations before us; we also still enjoy the relative

luxuries of the 21st century.

As my first full year with the CIBSE Ireland Committee

nears its end, I am now more aware of the power of unity

among apparent adversaries. Members of the Committee

have worked together to enhance the building services

industry in Ireland by way of technical evenings,

seminars, the annual conference and various awards

programmes such as the Sustainable Design Awards.

The latter in particular highlights just how critical

evidence-based research data is, not just in respect of

sustainability, but to building services and the world at

large, as a whole. We must continue to push the

boundaries of our capacity for innovation by working

together with our clients to present real-time data and

information about our successes.

We have even seen a recent winner of the CIBSE

Student Awards go on to spend time working with NASA

in the United States, highlighting how taking the first step

can open doors for engineers that would not ordinarily

have been envisaged. We have collectively sought to

protect our individual interests through highlighting

loopholes in legislation that affect us, such as BER

Assessor qualifications.

This current year has seen CIBSE Ireland set up the

first ever Building Services Young Engineers Network

branch based in Dublin. It is anticipated that this will give

a voice to the young engineers in the Dublin region,

promote participation by young engineers in the work of

CIBSE Ireland, and offer them the opportunity to enhance

their careers and broaden their professional networks.

We have recently received requests from young

engineers interested in participation and hope to convene

our first meeting of the YEN Dublin branch in March/April.

My ambition as CIBSE Careers & Young Engineers

38

So, by now you all probably knowmore about pensions, terms ofemployment and financialregulations than you care toremember. I know that I do! We have lived through the worst global recession in 80years and should have a better understanding of howunsustainable our success was,and how much it is dependent on the success of others.

Network Officer is to create a spirit of participation byyoung engineers. There is something of a void withinthe industry at present between graduation from thirdlevel and senior engineer level, where the vast majorityof engineers do not get the opportunity to have a voice,or participate in a wider debate, on issues of interest to them.

CIBSE Ireland recognises how important students atsecond and third level are to the future of engineeringas a whole, and specifically building servicesengineering. Second level students today are presentedwith infinitely-more information to shape and guide theirambitions for the future through the internet and otherforms of media. We are developing and strengtheningour links with second level schools and third levelinstitutions through careers and membershipinformation sessions, and would encourage employersinterested to come forward to highlight the opportunitiesthey may have in the short-term future for graduates,and the medium-term for second level students.

We must compete with other industries such asbanking, retail, communications and other engineeringdisciplines for the best and brightest students, toproduce the best engineers and ultimately deliver ontheir ambitions to create landmark designs and raisethe standard of building services engineering.

I have been surprised at how relatively fewconsultancies actually lend their voice to the CIBSEIreland committee. While acknowledging that there area number of related professional institutions in Ireland,CIBSE is dedicated to supporting the science, art andpractice of building services engineering. We do thisthrough engaging our membership to determine yourneeds and facilitating those requirements through CPDevents, our award nights, and the annual conference. I would encourage more consultancies and individualengineers to engage with us to help us meet your ever-changing needs in these increasingly-competitive times.

This year represents probably the most significantchallenge in living memory for almost every buildingservices consultancy in Ireland. Having endured thedevasttation wreaked on the industry in 2009, we arenow trying to avoid the double-dip downturn andachieve some form of stability. Everybody wants to beengaged with the current issues, everybody wants an

edge and everybody wants to be a step ahead of thecompetition. However, for our industry to remain healthywe must work together, challenge each other andensure that our horizons extend further than the lotteryof the next fee proposal. Entrenchment is a naturalreaction to adversity but now, more than ever, we must come together to increase our chances of short to medium term successes, and to protect the future of the industry.

Historically, we have seen positive competition withJames Joule and Lord Kelvin becoming greatcompanions, and negative competition with ThomasEdison and Nikola Tesla advocating the respectivevirtues of DC and AC current. The actions of ThomasEdison left a horrendous blemish on his reputation. We as an industry can fortify the foundations of ourindustry for future generations by working together,collaborating to ensure that we are motivated,challenged and educated enough to overcome theroadblocks we are currently encountering, and willcontinue to encounter, for some time into the future. �

Minister Ryan take a bowAs a total cynic when it comes to politicians, I have to say I was extremelyimpressed with Eamon Ryan, Minister for Communications, Energy & NaturalResources, when he attended the recent CIBSE Conference in Dublin

to perform the official opening.

It was obvious as he chatted beforehand, and from the content of his address, that he not only has a genuine interest in his portfolio, but that he is also very knowledgable on allmatters relating to it.

However, even more impressive still was the fact that he asked for questions from the floor having delivered his address

– I’ve never known a Minister do that at such an event.

Then, to cap it all, when he had answered all the questions, he sat with the other delegates tolisten to the next speaker’s address before leaving in a rush to make it back to the Dail for a cabinet meeting.

Very impressive Minister ... well done.

What function FÁS – training or dole queue reduction? As the national training and employment authority, I always understood FÁSto be responsible for anticipating the needs of Ireland’s constantly-changinglabour market, and for training people to satisfy those needs.

I took it as read that, when accepting people on to particular courses, theindividuals concerned were professionally assessed by FÁS to ensure that theyhad basic core skills, or education qualifications, appropriate to the course theywere embarking on.

For instance, allowing someone with no background, qualification or experiencein heating and plumbing say, undertake a gas or oil installer course would makeno sense. However, this is precisely what seems to be happening.

Where the fault lies is difficult to determine. It is very easy to blame FÁS, and nodoubt it has a responsibility in this area, but it too has a master, a political one atthat. It would appear that the urgency on the part of Government to get people offthe live register and on to any form of training scheme is taking precedence overthe vetting of who undertakes what course.

Yes people need to be trained, and re-trained, to upskill and enhance theiremployment opportunities. However, shoe-horning them in to trades andprofessions for which they are blatently unsuited is counter-productive andextremely damaging.

This practice is particularly prevalent in the gas installer and heating sector atpresent, unless Minister Hanafin directs FÁS to address the matter, a serious gas-related incident seems inevitable.
