NatHERS (Nationwide House Energy Rating Scheme) is now seeking consultation to include energy performance ratings for existing homes ahead of the launch in mid-2025. The recent updates to NatHERS will be leveraged to measure the home’s energy performance, providing ratings based on the home’s design, materials, constructions, fixed appliances, on-site energy generation and storage.

If you are building homes then you probably have heard about the National Construction Code (NCC) and NatHERS (Nationwide House Energy Rating System). And you may already know that the minimum energy rating will soon be changing from 6 star to 7 star. Meaning all of your projects will soon have to meet the 7 star energy rating threshold. Understandably, you will be worried about the extra costs associated with the extra star.

Since 2010, all new homes built in Australia have had to satisfy a minimum 6-star energy efficiency NatHERS rating, however, the Climate Council and the Property Council of Australia are now pushing to make a 7-star energy rating the new minimum. State and territory ministers will meet in July to review the 11-year-old laws that set the minimum energy efficiency standards in new home builds.

With buildings in Australia accounting for nearly 25% of carbon emissions it is not surprising that buyers are looking to build more sustainable homes.

Green Star is an internationally recognised sustainability certification for commercial buildings. It is considered the largest voluntary and holistic certification standard in Australia. The certification is managed by the Green Building Council of Australia (GBCA) who have announced an exciting update on Green Star for Homes standard.
