• An un-insulated valve loses as much heat as 1.2 m of pipe of the same diameter.
• Fitting a single insulation jacket to a 100mm diameter valve (4") will save $21 per year on a low temperature system (for heating to radiators).
• Fitting a single insulation jacket to a 100mm diameter valve (4") on a steam system will save $32 per year

• When a room is empty turn the lights off (even if you plan to come back in a few minutes).
• If daylight alone is adequate, leave your lights off, if you currently use tungsten light bulbs, it may be possible to replace them with compact fluorescent lamps
• Compact fluorescent lamps will give a 75% reduction in electricity use, and last ten times longer than tungsten light bulbs.
• Replacing a 60 Watt bulb with a 15 Watt compact fluorescent lamp will save $27 over the life of the lamp, and reduce CO2 emission by 193 kilograms (or 52 kilograms of Carbon).

• A PC left on overnight for a week uses enough energy to print 4,000 pages on a laser printer
• Leaving a PC on overnight and at weekends costs $45 per year
• If you can't switch off the PC base unit, switching off the monitor overnight and at weekends will save $26 per year.
• Leaving a PC and CRT monitor on continuously can release as much as 800 kilogram's of Carbon Dioxide per year into the atmosphere
• A photocopier left on overnight uses enough energy to make over 1,500 copies
• Leaving a photocopier on overnight and at weekends costs between $22 and $120 per year
• It costs about $12 per year to leave a small laser printer on standby continuously.
• If purchasing printers, question the need for individual machines. Networked printers will result in lower energy use
• If you are not going to use a computer, printer or piece of equipment for a while, turn it off. If you can't turn the computer off, turn the screen off
• Flat (LCD) screens for PCs use much less energy than CRT type monitors. If replacing equipment, consider the running costs.
• If you purchase new PCs, consider the running costs. Features such as sound cards, modems or multimedia may be unnecessary and will add to running costs.

• Check that maximum use is made of "zoning". There's no point heating the whole building if it's possible just to heat one area
• Check that when timings are altered for occasional activities, they are re-set as soon as possible
• Checking that plant controlled by a building energy management system (BEMS) is automatically controlled.
• If plant controls are switched to "manual" rather than "auto", the plant will run continuously regardless of BEMS settings

• A dripping tap or shower can waste 1,200 litres of water a year at one drip per second. If the drips are breaking into a stream, that water wastage could be as much as 32,000 litres per year
• 32,000 litres per year of water from a hot tap costs about $102 if the water is heated from gas.
• 32,000 litres per year of water from a hot tap costs about $167 if the water is heated using electricity
• 32,000 litres of cold water costs about $42

• Reducing room temperatures in winter saves money. A 1º C reduction to the thermostat setting reduces fuel use by 7 to 8%.
• Increasing thermostat settings in the summer will save money in air-conditioned areas
• Computer rooms do not need to be held constantly at 20ºC ±0.5ºC, and 50% relative humidity, ± 5%.
• Internal doors between areas with different temperatures should be kept closed
• Doors and windows in air-conditioned areas adjacent to non air-conditioned areas should be kept closed
• Corridors should be heated to 18º C only. Check settings of thermostatic radiator valves if fitted
• Ask your cleaners to let you know if parts of your building are hot (or too hot) when they start work
• Ask cleaners to leave doors between areas with different temperature requirements closed and not to prop outside doors open so floors dry more quickly
