At Ecomax Homes, we are proud to bring over 10 years of BASIX experience and more than 7 years of NatHERS assessment expertise across residential projects throughout Australia.
Learn how to achieve a 7 Star NatHERS rating in Australia. Improve thermal performance, reduce energy costs & meet NSW compliance.
Achieving a 7 Star NatHERS rating is becoming increasingly important for residential projects across Australia—especially in NSW and Sydney where energy efficiency standards continue to rise.
A higher NatHERS rating not only improves compliance with BASIX and the NCC, but also creates homes that are more comfortable, energy-efficient, and cost-effective to run.
As consultants working with architects, builders, and homeowners across NSW, we’ve seen firsthand how smart design decisions early in the project can dramatically improve thermal performance without blowing out the budget.
If you're planning a project, working with professionals offering NatHERS assessment Sydney services can help you achieve compliance faster and more efficiently.
NatHERS (Nationwide House Energy Rating Scheme) measures the thermal performance of residential homes on a scale from 0 to 10 stars.

Key areas:
Windows are one of the most important components in achieving 7 stars.
A well-sealed building envelope reduces unwanted heat transfer while maintaining indoor comfort.
However, ventilation must still be carefully designed to avoid condensation and overheating.
The most cost-effective 7-star homes usually rely on:
💡 Real Project Example:A Sydney home improved from 5.8 to 7.1 stars simply by redesigning window placement and upgrading insulation—without needing expensive renewable systems.
In NSW, NatHERS often plays a major role in BASIX compliance.
