recommends the Osram IRC (infrared coating) halogens available at www.lightingpro.com.au, which save 30--60 per cent energy with no loss of light. Insulation The Australian government reports that heating and cooling our homes forms up to 20 per cent of total energy use. Department of Climate Change and Energy Efficiency reports that 70 per cent of human made greenhouse gases come from the energy sector, specifically electricity generation. Good insulation is one of the best ways to reduce this figure. HRV, an HIA GreenSmart award winner, has developed a system that harnesses the heat captured on a rooftop and recirculates it around the house. The system provides every room with the equivalent heat of a 1000W heater, at a fraction of the cost. At night when the roof space temperature drops quickly, the cooler air is redistributed to create a more comfortable house during hot, sticky evenings. What's more, it's easy to install and Australian made. (See page 46). Glazing Minimising the rate of summer heat gain and winter heat loss can have a dramatic effect on heating and cooling bills, but double glazing can be expensive. ClearComfort is a thin, clear film that simply fixes onto window frames with heat, switched on Sustainability Victoria reports that 10 per cent of residential power is lost through standby items in the house, but a new product, FutureSwitch, can fix that. A plug which sits between the appliance power board and your power point, it is hooked up to a transmitter that cuts out the standby power supply at the flick of a switch, such as at night or when you go away. Another useful product is Efergy's series of electricity monitors, which enables users to track exactly how much energy is used in real time to determine what uses the most energy in the home.

It's affordable, easy to apply and can cut your household's yearly greenhouse gas emissions by 1.5 tonnes. Should you be looking at glass, Viridian is a highly sustainable glass system developed by CSR. It is the first manufacturer to sign a sustainability covenant with EPA Victoria and also has developed a Target of Zero Waste program to virtually eliminate packaging and inter-packaging materials in the delivery of its glass. Paint The paint market is now flush with Low E (low emissivity) and VOC (volatile organic compound) paints that help reduce heat and toxic emissions. Using these paints can save up to 20 cent on energy bills, and while there are many to choose from, Dulux offers an Eco Choice of high performance paints, and Resene has an Environmental Choice program as well, with both promoting their commitment to sustainable practices. gs For more information: HIA GreenSmart www.greensmart.com.au.
