Energy rating


All new homes, home renovations, alterations and additions need to comply with the 6 Star Standard as set out in the National Construction Code.

The 6 Star Standard applies to the thermal performance of a home, renovation or addition and includes the installation of either a solar hot water system or a rainwater tank for toilet flushing.

A 6 Star energy efficiency rating applies to your home's building envelope – its roof, walls, floor and windows.

6 Star requirements also include efficiency standards for lighting but not plug in appliances.

Minor building works, not requiring a building permit, will not be affected by the regulations. However, all new homes and building projects involving home extensions and major renovations will need to comply with 6 Star Standard.

Meeting 6 Star compliance is not difficult: it's about good design, particularly at the planning stages. So talk to your building practitioner early to take advantage of the benefits, such as increased comfort, saving money on energy bills and making your home more resilient to climate change. Carefully selecting your site so your home's orientation takes advantage of solar energy can add up to 1 “Star” to the rating.

6 Star homes are projected to use 24 percent less energy through heating and cooling compared to 5 Star homes. This will see Victorians with 6 Star homes potentially saving a further $100 off their energy bills each year. This is only an average saving, with residents who use their energy features in their home wisely saving even more.

Consider design options that go beyond minimum regulatory requirements: It will pay off in the long run and improve the value of your home.
