NatHERS Assessment
Ace Energy Assessments delivers expert NatHERS assessment services for residential homes across Australia. Our accredited assessors conduct thorough energy efficiency ratings and provide design-stage optimisation advice to help you achieve required 7-star NatHERS ratings efficiently.
We assess heating and cooling loads, building envelope performance, insulation specifications, glazing and window-to-floor ratios against your project's NatHERS climate zone. Whether you need a standard 7-star NatHERS report, a Performance Solution for complex designs, or advice on energy cost savings, we deliver accurate results and practical recommendations.
NatHERS (Nationwide House Energy Rating Scheme) is a star rating system that rates the energy efficiency of a home based on its design. The rating ranges from 0 to 10 stars, with higher ratings indicating better thermal performance. Most new homes in Australia are required to achieve a minimum 7-star NatHERS rating under the National Construction Code.
Under the NCC 2022 energy efficiency provisions, most new homes require a minimum 7-star NatHERS rating. However, requirements can vary by state and local council. Some developments and planning overlays may require higher ratings. Ace Energy Assessments can advise on the specific requirements for your project.
Under NCC 2022, your 7-star rating is only half the requirement. New homes also need a Whole of Home rating — a score out of 100 covering your heating, cooling, hot water, lighting and solar. We deliver both ratings together in one certifier-ready report.
