Buildings are central to creating more sustainable cities, and green ratings are often used to assess how well a building measures up against this goal. But the current system has serious flaws.
While new buildings may be the glamorous eco-home pinups, retrofitting existing homes is the main game when it comes to creating energy-efficient, comfortable housing stock for all Australians.
The law says that newly built houses should have a six-star energy rating, to help residents afford their heating and cooling bills. But some builders seem to be findings ways around this requirement.
Homebuyers want energy-efficient homes. The challenge is to present the relevant information in a way that taps into the typical house-hunter's mindset.
