2019 Software Accreditation Protocol

The Nationwide House Energy Rating Scheme (NatHERS) provides a standardised approach to rating the thermal performance of Australian dwellings.  

The NatHERS Software Accreditation Protocol outlines the requirements and processes for:

  • accrediting new energy rating software tools
  • updating existing accredited tools

This ensures that software meets standard requirements and produces consistent results in calculating energy loads and star ratings of residential buildings.

The star rating is used to meet minimum regulatory requirements for dwelling design under the National Construction Code.
