    • Office equipment / Page 4 Office equipment Whatever your business, the chances are you need some office equipment to operate, whether it be computers, photocopies, printers, fax machines etc. In some companies, office equipment can be responsible for up to around 30% of total energy consumption. Using equipment more efficiently can therefore make a significant difference to energy spend. Savings in practice: Just by turning off the TV in their café when no-one’s watching it, Independent Motor Auctions in Leeds could cut their energy bill by around £26 a year. (Based on prices in 2008) Easy ways to save on office energy expenditure Only switch on what you need Enable energy saving features on all equipment A photocopier left on unnecessarily could increase your energy Power consumption could be reduced by up to 80%. Enabling bill by up to around £194 a year. power save on a laser printer could save up to around £11 per year or more. Consider whole life cost approach when you buy equipment An energy star compliant laser printer could reduce your energy Avoid using screen savers as they rarely save energy bill by around over £19 per year. Sometimes screen savers use more energy. Turning off a screen saver and activating the power save function on a computer Turn off computer monitors when you leave monitor could save around £25-£45 per year per monitor. A 17” tube monitor left on unnecessarily could cost up to around £37 per year. Keep photocopiers outside air conditioned spaces This may save up to around £200 per year in ‘warming-up’ costs Save up photocopying until you have a batch for each copier. Photocopiers use a lot of energy when they’re first switched on and when they’re left on because they need to be warm Avoid printing emails to work. For maximum efficiency, save up copies into a batch You can save paper, toner/ink and energy by not printing emails and then turn the copier off again. This could save you up to and documents that aren’t strictly necessary. The energy alone around £194 a year. could be worth around £6 or more per year, per printer. Avoid copying documents unnecessarily Cutting down on paper, toner (or ink) and energy could lead Find out more ways of saving energy with office equipment to a saving of around £50 per year.

    • Space and water heating / Page 5 Space and water heating Heating your business premises and ensuring adequate hot water can use up a lot of energy. For maximum efficiency, aim to match your space and water heating to the occupancy of the building and regulate it to maintain the desired temperature. Top tips to reduce heat waste Ensure thermostats are set to the desired temperature for Turn off boilers during the summer months heat and hot water Using an immersion heater during the summer could save For every 1˚C of extra heat, your heating bill increases by around around £20 per year, although circumstances vary. 8%. For warehouses, 16˚C is usually an acceptable temperature, Ensure your hot water cylinder (calorifier) is well insulated and 20ºC for offices. For hot water, between 60˚C and 65˚C If you spend around £160 per year on hot water, this could be is suitable for catering and washing to avoid Legionella (any halved with an insulated cylinder. higher can also increase limescale build-up).

    • Buildings / Page 6 Buildings Effective insulation and draught proofing is essential to reduce heat loss from buildings – as well as limiting any noise and airborne pollution. Most buildings have scope for improvement. Good insulation is best fitted during the construction or refurbishment of a building when it is more cost effective and less disruptive. However, there are still changes that you can make to existing buildings at any time. Good housekeeping for more energy efficient buildings Seal external doors and windows with draught excluders Ensure room temperatures are thermostatically controlled By fitting self-adhesive draught excluders to outside doors If you spend £600 per year on space heating, you could reduce and windows, you could save around £20-£40 on a typical your energy bill by about £48 for each degree the temperature heating bill of £400. is reduced.

    • Air Conditioning / Page 7 Air Conditioning Air conditioning can be a blessing during summer months, but it doesn’t need to run 24/7. Nor should it run too cold. Both will increase energy costs considerably. Savings in practice: By adjusting temperature settings on air conditioning from 21˚C to 23˚C, the Queen’s Arms pub in Brighton could save around £232 a year. (Based on prices in 2008) Keeping cool for less Ensure thermostats are set to the desired temperature Minimise the use of other office equipment that For every 1˚C below 24˚C, you could be adding 8% to your generate heat air conditioning bill so check regularly that your room One 17” desktop PC monitor left on unnecessarily could cost temperature thermostats are set correctly.

    • Lighting / Page 8 Lighting Every business needs lighting in one form or another and uses a significant amount of energy simply so that people can see to do their jobs properly. Retail outlets also rely on display lighting so that their goods are correctly lit to make them visible and appealing. While natural lighting is often preferable, it’s not always available or practical. Many businesses also have changing needs throughout their work hours. So artificial lighting is a necessity. The key to being more energy efficient with lighting is having a system that produces the maximum amount of light for the input power and is flexible and responsive to changing circumstances. The control system is therefore crucial. Savings in practice: Simply by replacing 4 x 58 watt T8 fluorescent tubes in their main office with T5 conversions, Regency Press in Birmingham could save more than £30 a year. (Based on prices in 2008) Simple steps to reduce lighting bills Check lighting levels Fit a time switch to control fixed hours of lighting You may have more light than you need. Removing an Each 70 watt lamp lit all night, when part night operation unnecessary 100 watt incandescent bulb could save about would do, costs around an extra £14 per year. £20 a year. Label light switches Turn off fluorescent lights when not needed Only turning on lights that are needed will save money – a A popular myth is that it’s not worth turning off fluorescent fitting with 4 x 18 watt lamps will cost about £17 a year to run. lights for short periods. This isn’t true. Turning off a single Fit daylight and/or occupancy sensors to lights 65 watt fluorescent fitting at break times could save around For a group of 6 x 80 watt fluorescent fittings, savings in the £4 per year. order of £51 per year could be achieved. Turn off unnecessary lights Replace incandescent bulbs with compact fluorescent bulbs Each twin 58 watt fluorescent fitting costs about £23 a year Standard incandescent lamps are inefficient, generating 10% to run. light and 90% heat. Swapping a 20 watt low-energy lamp in Rewire lighting controls for small groups of lights, or place of a 100 watt incandescent lamp could save you around even individual lights £16 a year. The more control you can have over the light you use, the less likely you are to waste energy. So consider fitting dimmer switches, automatic presence or sunlight detector sensors.RF5902 npm7847 E3 Energy Efficiency Guide A4.indd 8 21/09/2012 16:30
    • Lighting / Page 9 Use task lighting rather than light the whole area Consider turning off external lighting A single 18 watt task light instead of an overhead fluorescent Rather than leaving lights on all night, fit motion sensors. For light with 4 x 18 watt tubes could save about £12 per year – a typical 300 watt tungsten halogen lamp, you could save up to enough to cover the cost of buying the task light. £20 a year. Where lights are required to be lit all night, choose discharge lighting – a 70 watt high pressure sodium lamp rather Replace 38mm fluorescent tubes with 26mm tubes than a 300 watt tungsten halogen lamp saves around £42 over For each 65 watt bulb substituted with a 58 watt lamp, you’ll the year. save around £3 per year – more than the cost of the new bulb. This will usually work with lamps that have starters, excluding 8ft fittings. If in doubt, try one first. Want to know more about lighting? The following organisations can all help with queries about Consider whole life cost approach when buying lighting internal and external lighting and the various methods of control: By replacing twin 80 watt fluorescent fittings with new twin 58 watt high frequency fluorescent fittings, you’ll make energy • The Carbon Trust savings of around £13 per fitting.

    • Electric motors / Page 10 Electric motors Electric motors are major users of electricity in industrial plant and commercial premises. Motive power accounts for almost half the total electrical energy used in the UK and for nearly two thirds of industrial electricity use. Consider what the motor is actually doing. Is it doing useful work? If not, turn it off. Maximise motor efficiency Prevent unwanted motors running Connect oversized motors in permanent A 4kW motor turned off for an hour a day could save about star configuration £100 a year. A 50kW motor turned off for an hour a day An oversized motor costing £200 per year to run could could save over £1,200! reduce its cost to around £180 if connected in permanent star formation. Slowing down a motor could make significant energy savings Use high efficiency motors Fitting variable speed drives could lead to significant energy A high efficiency EFF1 rated motor used in place of a 25kW savings with paybacks between three and five years. A motor basic motor running continuously all year, could save taking 14kW at 1,500 rpm and costing £1.19 per hour to run about £400. could drop to around 9p an hour to run if adapted to around 1kW at 750 rpm. Want to know more about motors? Then contact: Use direct drives rather than belt drives • The Carbon Trust A 12kW motor driving a pump directly, rather than via a belt, www.thecarbontrust.co.uk could save about £260 throughout the year. Tel 0800 085 2005 On belt driven systems, ensure pulleys are properly aligned A 10kW motor driving a pump with pulleys that are not properly aligned could add around £220 to the annual energy cost. Changing pulley ratios on fixed speed motors could lead to significant energy savings Slowing a motor down by simply changing the pulley ratio is very cost effective for fixed speed motors and could achieve paybacks in under a year. A motor taking 6kW at 3,000 rpm and costing 51p per hour to run, for example, could take less than 1kW and cost less than around 7p per hour to run at 1,500 rpm.RF5902 npm7847 E3 Energy Efficiency Guide A4.indd 10 21/09/2012 16:30
    • Compressed air / Page 11 Compressed air Compressed air is a convenient and often essential utility, widely used in industry. However, it takes a lot of energy (usually electricity) to generate and consequently is very expensive. For example, it costs up to ten times more to run air tools than their electric equivalent, because only 10% of input energy to a compressor is doing useful work while the other 90% is rejected as heat. Up to 30% savings are possible by following some simple good housekeeping measures, often achievable at no or low cost. Steps to reduce the cost of compressed air Consider heat recovery required could be costing you dearly in energy and filters. Drying It could yield up to 40% of the compressor’s input power as also costs significant amounts as the air has to be cooled to a ‘free’ heat source. separate the moisture. Ensuring that you are filtering and drying to the required standard and no more could lead to significant Ensure compressed air is used appropriately financial savings.

    • Commercial boilers / Page 12 Commercial boilers Many boilers are small and compact and are used for space and water heating applications, particularly in the smaller commercial and retail business sectors. Some larger buildings and many industries will have much bigger boilers (or a combination of boilers) and these need to be considered more specifically than the smaller, individual packaged boilers. It’s worth noting that not all of the heat produced by a boiler is useful. Some is lost up the flue, some through the boiler case and some through leaks in the system. With steam boilers, heat will also be lost during blowdown (a process that helps to prevent the boiler clogging up with particles left over when water is converted to steam). Further losses can occur if the condensate (what’s left when the steam turns back into water) is not collected and re-used. So there are lots of ways to limit energy waste and maximise efficiency. Savings in practice: Updating their old hot water boiler with a new energy efficiency boiler could save Bristol-based pie makers Pieminister around £155 a year, with a payback period of less than three years. (Based on prices in 2008) Getting the best from boilers Replace old boilers Act to detect problems with boilers All modern boilers have a better efficiency than their older Regularly monitoring flue gas temperatures and the counterparts, so replacing an old boiler with a new one composition of the flue gas itself can lead to early detection could save as much as around 30% depending upon of a problem with your boiler. Either consult an expert or have individual circumstances. automatic monitoring equipment fitted. Downsizing a boiler could lead to savings Ensure that a minimum number of boilers are running Boilers were often oversized, so there may be an option to In multiple boiler installations, a sequencing control device downsize, which could lead to additional savings. However, should be used to ensure that the minimum number of replacing a boiler can be an expensive option and may cause boilers are running fully loaded, rather than all boilers considerable disruption, so it may be worth considering other running on part load. measures first.

    • Refrigeration / Page 13 Refrigeration Refrigeration energy costs British industry around £300 million a year and rising. In certain sectors – notably food and drink, chemicals, food supermarkets and cold storage – it accounts for a significant proportion of overall site energy costs. A small percentage reduction in refrigeration energy could therefore represent huge financial savings. Many refrigeration units can be improved to save up to around 20% of their energy consumption. Much of this can be done at little or no cost, with paybacks on any investment of well under two years being the norm. Chilling at maximum efficiency Is cooling really needed? Insulate refrigerant pipes A freezer cooling 2˚C lower than necessary and costing £190 Pipe insulation is very good value for money and will keep a year to run could be wasting around £30. running costs down.

    • Process plant / Page 14 Process plant Process plant covers a diverse range of equipment, including dryers, furnaces, baking ovens, mixers and blenders, crushers and grinders, tanks and vats, treatment booths and many others used for specialist jobs in industry. However, this equipment is often overlooked when people are thinking about energy efficiency because it’s seen as too specialist. Concern about product quality can often hinder trying anything new. But there are some simple house-keeping measures that can reduce energy costs significantly. Using process plant effectively Shut down unnecessary plant Consider options for improved controls for Preventing any unwanted plant from running will save the full existing processes input power to the plant. For example, a 15kW kiln turned off A control system that maximises through put but minimises at night when not needed could save over £2,000 in a year. costs is the ideal set-up and could lead to savings.

With volatile and increasing fuel prices, it has become imperative that we all seek to use less energy. As well as moving towards more efficient use of energy, XYZ Co Ltd will strive to source its energy needs from renewable sources, which will further protect the environment. It is hoped that over the next two years, XYZ Co Ltd will have saved a minimum of 10% of its energy use by the adoption of best practice, modern engineering solutions and by the encouragement and commitment of its employees to use less energy. These savings can be channelled into further energy saving initiatives and front line services in support of our main business activities. We’ll renew this energy policy at regular intervals and update it to take into account changing circumstances and to ensure it provides opportunities for continuous improvement. The responsibility for overseeing the energy policy and for subsequent reviews has been delegated to Mrs Somebody, who will be supported by Mr Someone. Please give them your whole hearted support.

    • Sample Energy Policy / Page 19 Energy Policy Statement This document sets out the goals, objectives and targets for the sustained reduction in energy use throughout the XYZ Co Ltd organisation. This energy policy forms the basis of a two-year energy saving plan, which will lead to environmental benefits and lower operating costs. The energy policy will run between August 2011 and July 2013 and will be reviewed every six months to ensure the goals, objectives and targets are on track and to incorporate any necessary changes. It is the intention of XYZ Co Ltd to: • Publish our corporate energy policy. • Purchase environmentally friendly energy, where we are not disadvantaged by so doing. • Adopt a whole life costing approach to purchases, where particular attention is paid to energy efficiency. • Reduce energy consumption, and thus reduce carbon emissions. • Improve overall energy efficiency. • Engineer solutions for saving energy rather than rely solely on manual intervention. • Encourage and motivate employees to save energy. • Publicise these objectives. • Ensure all items identified in our action plan have been implemented. • Introduce energy conservation into the induction process for all new employees, Targets XYZ Co Ltd has agreed to a sustained reduction in energy consumption, year on year, by the adoption of the two-year energy saving plan. The individual targets for reductions in gas and electricity are detailed below. The base year for statistical purposes will be 2008 and all targets will be set and measured against this. Gas For gas, the plan is to reduce consumption by around 5% per year over the next 2 years, leading to a total reduction of 10% in gas usage by 2013. This will be measured by kWh/m2, and weather conditions will be taken into account. Electricity For electricity, the plan is to reduce consumption by around 5% per year over the next 2 years, leading to a total reduction of 10% in electricity usage by 2013. This will be measured by kWh/m2. Date: Date:RF5902 npm7847 E3 Energy Efficiency Guide A4.indd 19 21/09/2012 16:30
