Australian houses are super leaky

The Australian government's Your Home: Design for Lifestyle and the Future, Technical Manual 4th Edition (2008) states:

• Overseas standards and research recognise that the weather proofing or
draught sealing of houses is the most effective method of achieving direct energy savings

• Australian buildings leak 2-4 times as much air as North American or European buildings, suggesting a tremendous opportunity for energy savings in Australia

• Australian households produce ~ 20 per cent of our total annual greenhouse gas emissions, of which heating and air-conditioning account for around 38 per cent

Draughts can account for up to 25% of heat loss from a home
