Nationwide House Energy Rating Scheme

An accredited software tool assesses the home based on a variety of criteria and produces an energy star rating.

[1] Under FSDR, the basic elements of glass, mass and insulation were the basis of the design principles of a five-star home.

[citation needed] During 2006, requirements for 5-star energy ratings were introduced for new homes through the BCA in Western Australia and the Australian Capital Territory.

As of 2022[update], house plans and building specifications, which outline the structure, design and materials, are used as input data.

A NatHERS-accredited software tool estimates how much heat is required to be added or removed to keep the building thermally comfortable, and generates a star rating out of 10, along with a certificate.

[4] By 2020-2021, approximately 90 per cent of building approvals were assessed using the scheme, in order to show compliance with the National Construction Code.
