NatHERS stands for Nationwide House Energy Rating Scheme. NatHERS enables windows and doors to be rated and labelled for their annual energy impact on a whole house, in any Australian climate.
NatHERS assesses a home’s potential heating and cooling energy use. The scheme uses a star rating system to rate the energy efficiency of a home, improving liveability and helping home owners save on energy bills through smarter design planning.
NatHERS star ratings meet the mandatory energy efficiency requirements of the National Construction Code of Australia.
