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.
