What is NatHERS

The Nationwide House Energy Rating Scheme (NatHERS) is an Australian initiative that provides energy ratings for new dwellings.

It aims to create energy-efficient, resilient, and comfortable homes for the future that cost less to run.

Here are some key points about NatHERS:

  • NatHERS provides a star rating out of ten based on an estimate of a home’s potential heating and cooling energy use.
  • The NatHERS scheme has been upgraded to provide world-leading measurement tools that the building sector can use to support the move to net zero emissions by 2050.
  • NatHERS can now rate the energy performance for the whole home including major appliances, solar panels, and batteries, in addition to the star rating for the building shell.
  • NatHERS provides a streamlined pathway to meet or exceed the new National Construction Code (NCC) 2022 energy efficiency requirements.
  • The minimum requirement for new houses and apartments is 7 stars (out of 10).
  • A new annual energy use budget will also apply, to account for a home’s major fixed appliances and any energy generated from solar panels/PV.
  • NatHERS is administered by the Department of Climate Change, Energy, the Environment, and Water on behalf of the states and territories.
