Green Star – Performance: The Rating Tool

Categories and Credits

Green Star – Performance assesses the operational performance of buildings. It provides a rigorous and holistic rating across the following nine impact categories:


Submission Guidelines

Submission Guidelines provide detailed information on credit aims, criteria, additional guidance, background information and resources. 

The Submission Guidelines are available at our online shop. The guidelines are free to download for all members and available for purchase to non-members.




The scorecard is an interactive Excel spreadsheet that must be used by projects seeking Green Star certification. The scorecard provides a scoring tool for projects to keep track of their Green Star points claims. The scorecard is also used by the GBCA to provide the results of assessment.

Submission Templates

In all credits, the project team must submit a Submission Template summarising the steps taken to ensure compliance with the credit criteria. The Submission Template is the principal method by which the project team communicates with the assessment panel. It specifies the information and narrative required to confirm that the project complies with the Credit Criteria. The Submission Template will ask project teams to justify their claims with evidence that must be included in their submission.

Projects must submit these Submission Templates and are not permitted to use an alternative document.

Submission Templates are provided in MS Word format. There are no automated or 'smart' features embedded within these Submission Template. Project team are to fill in and edit Submission Templates to suit their responses in the areas indicated within each Submission Template. Feedback on these template is welcomed.
