From 1 May 2011, all new homes, home renovations, alterations and additions will need to comply with a 6 Star Standard when it comes into effect in the Building Code of Australia.
This requirement was phased in with Queensland, ACT and South Australia commencing in 2010, with the remainder of the states and territories set to come on stream in 2011.
According to the Building Commission Victoria, the 6 Standard applies to the thermal performance of a home, renovation or addition; plus the installation of either a solar hot water system or a rainwater tank for toilet flushing.
Some simple building work, not requiring a building permit, will not be affected by the new regulations. However all new homes and building projects, involving home extensions and major renovations, will need to comply with 6 Star.
A 6 Star energy efficiency rating applies to your home's building envelope - its roof, walls, floor and windows.
6 Star requirements include efficiency standards for lighting but not plug in appliances.
