Nationwide House Energy Rating Scheme (NatHERS)

Last updated: 5 November 2017
NatHERS star ratings provide information about the thermal performance (heating and cooling needs) of a home construction. Star ratings are based on information about the home design, construction materials and the climate where it is being built.
The energy efficiency of appliances (such as air conditioners) are covered under the Greenhouse and Energy Minimum Standards (GEMS) and not measured as part of the NatHERS star rating.
NatHERS Star Ratings are conducted by professionals using purpose-built software . Star ratings can be used by homeowners, builders, certifiers, councils and local, state and national governments for a number of purposes, including:

To meet the mandatory energy efficiency requirements for homes and major renovations based on the National Construction Code

To advise home owners, architects and builders on the energy efficiency of various house designs

To advise prospective home buyers on the thermal performance of a home they are interested in buying
