The Housing Industry Association (HIA) has discredited the energy star rating system used to assess new houses.
The HIA assessed the energy rating of an identical home in every capital city last year using three different energy rating programs, designed by private companies and endorsed by the Federal Government.
The software programs are meant to give consistent results but instead produced vastly different ratings for the same new homes.
Kristin Tomkins from the HIA is calling on the Government to urgently review the programs.
"The worst result we found was in Brisbane. A two-storey house in Brisbane had a 3.2 star difference between the highest and the lowest score," she said.
"If we are looking to significantly reduce our greenhouse gas emissions from the housing sector, consumers and builders need to have confidence."
The HIA says the Government would need to allocate hundreds of thousands of dollars to correct the schemes.
