from almost everything we do

Drivers for Energy & Carbon Management

• Legislation is Strengthening– Climate Change Levy– Changes to Building Regulations, 2006/2010/2013 – EU Energy Performance in Buildings (EPBD)

Directive 2008– Energy Using Products Directive, (SI 2007

No:2037)

• Carbon Reduction Commitment– Large organisations whose annual mandatory half

hourly metered electricity use is above 6,000MWh – focusing on those emissions outside the Climate Change Agreements (CCAs) and outside the direct emissions covered by the EU Emissions Trading Scheme (EU ETS).

Climate Change – What’s Happening?

Climate Change – What’s Happening?

0.6°C Average global temperature rise since records began in the 19th Century

All 10 of the hottest years have occurred since 1900

Creating an energy awareness programme depends on your own particular circumstances. Some sites are more advanced than others, while some individuals are less energy aware than their colleagues.

There are four essential steps:

Practical Introduction to Energy Awareness

A Practical Introduction to Reducing Energy - Lighting

Lighting is essential for carrying out daily business activity but it can account for up to 40% of a company’s total electricity bill.

Automatic lighting controls can save 30% on costs.

Lighting costs can be reduced by 20% by only using electric lighting when the space is occupied

A Practical Introduction to Reducing Energy - Lighting

Use the sun. Encourage staff to keep lights off where there is sufficient daylight.

Clean windows and skylights regularly. If you can, angle blinds to reflect more light onto the ceiling or into the workspace.

General Energy Saving Opportunities - Office

Every office needs a range of equipment in order to function and be productive, but did you know that you could cut your office energy use by over 70% at little or no cost?

General Energy Saving Opportunities - Office

PCs/Monitors use almost half the energy of all office equipment

Switch off PC monitors and other equipment if they will not be used for 15 minutes or more day

A Practical Introduction to Reducing Energy - Refrigeration

A chiller door left open for 30 minutes a day wastes enough energy in a year to power a lighthouse for nearly 4 days.

An open chill door will cost you at least £2 an hour and a deep-freeze £6 an hour.

A Practical Introduction to Reducing Energy - Refrigeration

You don’t have to refrigerate many products below the recommended temperatures: increasing thetemperature of the cooled space by just 1ºC could reduce energy consumption by 2%.

Repair any leaks as soon as possible and rechargethe system with fresh coolant. Your refrigerationmaintenance supplier will be able to do this.

Keep condensers clean and free from blockages so that there’s enough space for good airflow away from the unit.

A Practical Introduction to Reducing Energy– Compressed Air

Compressed air leaking through a single 3mm hole could cost you over £500 per year!

Over 10% of electricity supplied to industry is used to compress air. However, as much as 30% of this energy is lost through leaking systems

A Practical Introduction to Reducing Energy– Compressed Air

Don’t compress air to pressures higher than is really necessary

Leaving compressors running when they aren’t required, such as during breaks

An idling compressor can still use 40% of its full load.

Having hot, wet or ‘dirty’ airmeans that the compressor has to work harder.

A Practical Introduction to Reducing Energy– Heating

Around 20% of heat generated by a boiler goes straight up the chimney. This can increase to over 30% if the boiler is poorly operated or maintained.

Simple maintenance can produce significant energy savings — often as much as 10-15%

A Practical Introduction to Reducing Energy - Heating

Make sure that your boilers are turned off when there’s no demand for heat, especially when buildings are unoccupied in the evenings and at weekends.

Be sure to stop all leaks in water, heating and steam pipes.

Good boiler maintenance is essential to ensure efficient combustion. Have your boiler serviced regularly.

• Check buildings are not heated above 19°C.

• Reducing the temperature by 1°C can reduce your energy consumption by 10%

• Check buildings are not cooled below 24°C.

• Energy consumption will rise by 8% for each 1°C difference

• Do not open windows when heating or cooling offices

A Practical Introduction to Reducing Energy - Insulation

Many businesses waste a significant proportion of energy through poor insulation of their heating or steam system.

An un-insulated valve is equivalent to 1 metre of un-insulated pipework.

An un-insulated flange is equivalent to 1/2 a metre of un-insulated pipework.

Every un-insulated metre of pipe could cost you around £100 a year

A Practical Introduction to Reducing Energy - Insulation

Don’t underestimate the amount of heat that can be lost through poorly insulated pipework. Remember – this waste heat is probably leaking into unwanted areas.

Don’t leave any gaps in your insulation

Insulation should begin where the pipe leaves the boiler

Replace any insulation that feels wet, it won’t prevent heat loss and will speed up pipe corrosion.
