Nationwide House Energy Rating Scheme

The Nationwide House Energy Rating Scheme (NatHERS) is an Australian Government program that provides a standardized framework for assessing the thermal performance of residential buildings. Using accredited software and trained assessors, NatHERS evaluates how well a home's design and construction regulate indoor temperature, producing a star rating from 0 to 10. A higher star rating indicates that occupants will require less artificial heating and cooling to stay comfortable, reducing both energy bills and environmental impact.

NatHERS sets national standards for both the professionals who conduct assessments and the software tools they use, ensuring consistency and reliability across the country. The scheme is widely used during the design phase of new homes, allowing architects, builders, and homeowners to make informed decisions before construction begins. A NatHERS rating is also commonly required as part of the building approval process in Australian states and territories.

This program is relevant to building designers, architects, energy assessors, and construction professionals working on residential projects in Australia. Becoming accredited as a NatHERS assessor enables practitioners to offer thermal performance assessment services and help clients meet regulatory requirements, while contributing to broader national goals around energy efficiency in the built environment.
