The Nationwide House Energy Rating Scheme (NatHERS) is a star rating system (out of ten) that rates the energy efficiency of a home, based on its design. NatHERS is administered by the Department of the Environment and Energy on behalf of the states and territories.

By providing a ‘measuring tape’ to estimate a home’s potential heating and cooling energy use, NatHERS helps to make Australian homes more comfortable for their inhabitants and also helps residents to save on energy bills through smarter design choices. Often good design can reduce the amount of energy needed to keep a home comfortable with no or little additional construction cost.
