Winter is now well upon us, and many of us – especially those living in old homes – are discovering just how draughty they are. In fact, Australia has some of the least air-tight homes in the world.
But there’s good news. New research by CSIRO, which I led, shows Australia’s newly built homes are far less permeable than they used to be.
We tested the air-tightness of 233 new dwellings in Melbourne, Sydney, Brisbane, Canberra and Adelaide, and found a significant improvement compared to homes built nine years ago. We also identified where most leaks occur.
