Through an agreement with the building sector, the Australian Government has resolved to eliminate worst energy performance practices through a national standard approach to minimum performance requirements for buildings, see Greenhouse Office website.
Based on this advice, the Australian Building Codes Board is set to consider the introduction of five-star energy regulations in all new homes when it meets today.
But the Housing Industry Association say it is all a crock. According to their media release:
The regulations will not deliver a significant reduction in greenhouse gas emissions, nor making significant inroads into energy savings. By 2020 they will have imposed a $31.5 billion cost on Australian families for a saving of just 0.8 per cent of greenhouse gas emissions.
