What are 6 and 7 Star Energy Ratings
A 6 and 7 Star Energy Ratings is a measure of the amount of energy that it will take to heat and cool a home to maintain a comfortable temperature throughout the year. To rate a home, the design is modelled with Home Energy Rating Software by a sustainability consultant accredited under the Nationwide House Energy Rating Scheme (NatHERS). Everything including the floors, walls, ceilings, roofs and windows are modelled to allow a detailed understanding of what parts of the building will be comfortable and what parts will be reliant on high amounts of heating and cooling.
Prior to May 2024, it was a National requirement that a rating of 6 stars out of 10 were met. From May 2024, and with the introduction of the 2022 National Construction Code, a requirement for a rating of 7 stars out of 10 will be introduced. Please note, there are variations between States and we recommend getting in touch with the Green Rate team to confirm which star rating is required.

How do I get a 6 or 7 Star Energy Rating completed
In all states except NSW, once the Building Permit drawings have been prepared and shared, the Green Rate Team will review and provide a detailed quotation. Once approved, the Green Rate Team will begin the assessment utilizing the following steps:
In NSW, once the DA drawings have been prepared and shared, the Green Rate Team will review and provide a detailed quotation. Once approved, the Green Rate Team will begin the assessment utilizing the following steps:
Why does getting a good quality Energy Rating matter
Obtaining a good quality energy rating it critical for ensuring appropriate insulation and glazing specifications are recommended.
This can have significant ramifications for the feasibility of the proposed design and to ensure that there are no nasty surprises during the build. In addition to this, a good quality analysis can ensure a comfortable home year round which minimises the use of artificial heating and cooling.
The Green Rate Difference
The Green Rate Team take a ‘boots on the ground’ approach when assessing any development. Extensive industry experience combined with constantly researching new building practices, products and local regulations, we ensure that our assessments are not just written to pass Council review, but to be a useable, realistic and cost effective plan for building a sustainable development.
