Green Star certification is a formal process during which a building, fitout, or precinct is awarded a rating by an independent, third party assessment panel of sustainable development experts through a documentation-based assessment. A Green Star certified rating provides independent verification that a building or community project is sustainable.

Get familiar with the documentation needed to demonstrate that your building, fitout or community meets Green Star's sustainability benchmarks with our submission guidelines.
Submit your documentation to the GBCA for Green Star assessment.
Green Star submissions are reviewed by an independent panel of sustainable development experts and an overall score is assigned.
A Green Star certified rating is awarded as a third-party verification of a project's sustainability.
Once you've reviewed the above, you can submit the registration form for your project online. A project is considered to be 'registered' when the terms of the certification agreement are accepted, and the certification fee is paid.

The requirements you need to meet, and documentation you need to submit for assessment, are outlined within the Green Star rating tools, including the Submission Guidelines, Scorecard and Checklist, as well as a range of submission templates, calculators and guides.
These are available to download from the GBCA website:
The Green Star Submission Checklist outlines the structure of the documentation you submit for assessment.
Once you have the documentation compiled, please send this to the GBCA for assessment, via your Green Star Project Manager.
Our third party certified assessor(s) will then review the documentation for compliance with the Submission Guidelines.
Within the standard certification process, there are two rounds of assessment. At the first round of assessment, points can be awarded and the project can be certified, or points may not be awarded and the project is provided with comments and the opportunity to address these items at the second round of assessment. During the Round 2 assessment, additional documentation addressing the Round 1 comments is assessed.
When the results of the assessment have been validated and awarded the Green Star rating, the GBCA will award a Green Star certified rating.
When a certified rating is awarded, the project will receive a certificate and is granted the use of the Green Star certification trademark.
While the Green Star rating tools are freely available, a design, project or building cannot publicly claim or promote a Green Star rating or use the Green Star rating logo unless the GBCA has validated the project's achievement through formal assessment and certification.
The Green Building Council of Australia operates a quality management system which complies with the requirements of ISO 9001:2015 for the development, upkeep and delivery of Green Star Certification.
