From 1 May 2011, the 6 Star Standard was introduced in Victoria
The 6 Star Standard applies to the thermal performance of a new home, home renovations, alterations, additions and relocations plus the requirement to install a solar water heater system or a rainwater tank for toilet flushing in new homes.
The requirements to install a solar water heater system or a rainwater tank for toilet flushing are set out in the Plumbing Regulations 2008 and apply to all new Class 1 buildings.
