The article 'Windows glazed over on energy use', The Age May 28 2007, discusses the issue of Australia being well behind the rest of the developed world in the thermal operational performance of windows. The AGGA energy committee chairman has even said we are about 20 years behind the US and Britain. The article state that up to 49 per cent of heat can be lost and up to 87 per cent of solar heat gain can occur through non-energy-efficient windows in an otherwise well insulated house. It presses for double glaze windows to be mandatory for a house to receive a 5-Star rating.
