Using Science to Get the Most Out of New Windows

Australia’s Sustainable Window Alliance (SWA) is using science to measure the properties of energy efficient windows for residential applications. The groups says that while windows represent only 8% of a home’s exterior surface, they can account for up to 60% of unwanted heat loss in winter and 91% of unwanted heat gain in summer … and that…

Up to 30 percent of home energy losses are through the windows of a property. Why is this loss so huge? Many homes use poorly made windows, which can lose a very large amount of heat when it’s cold outside (we’ll start by focussing on this process rather than concentrating on how windows can cause a room to warm up when it’s hot outside and cool inside).
