Millions of homes were built before Australia introduced housing energy efficiency standards in 2003. They’re leaky. Gaps around windows, doors and between building materials allow air to move in and out. So people tend to compensate, with more heating and cooling. It’s costly and damaging for the environment.
Using a national sample of 102,000 Australian homes across all 69 climate zones, we identified the most common housing types. Then we worked out how to make them “climate ready” and what benefits would flow.
