Green Star – Performance assesses the operational performance of buildings across nine impact categories.
The current version of the rating tool is: Green Star - Performance v1.1. This was released on 08/04/2016.
Aims to encourage and reward the adoption of practices and processes that support best practice sustainability outcomes throughout a building's ongoing operation and aims to improve a project's sustainability performance by influencing areas where decision-making is critical.
Aims to improve occupants' experience of the space, by encouraging and rewarding initiatives and measured outcomes relating to attributes that enhance the comfort and well-being of occupants.
Aims to reward building owners for implementing strategies and taking actions to measure and reduce a building's operational energy use, below that of a comparable standard-practice building.
Aims to reward projects that facilitate a reduction of building occupants' dependency on single occupant motor vehicles as a means of reducing overall greenhouse gas emissions by influencing commuting habits based on location, and on transport-related services offered.
Aims to reward building owners for implementing strategies and initiatives that reduce the consumption of potable water in building operations associated with cooling, irrigation and occupant amenities, below that of a comparable standard-practice building.
Aims to address the consumption of materials that go into, or come out of, a building during the operational phase of its life cycle, through sustainable procurement and purchasing and the management of waste.
Aims to reward buildings that minimise harm to the local ecology of the site, by discouraging environmental degradation, and by encouraging the restoration of natural environments whenever possible.
Aims to address the environmental impacts of 'point source' pollution generated by buildings to the atmosphere and local waterways.
Aims to recognise the implementation of innovative practices, processes and strategies that promote sustainability in the built environment.
Innovation Challenges, found within the Innovation category, are designed to encourage and direct investment in solutions that address a wide range of social, economic and environmental sustainability issues. Some Innovation Challenges will take the form of new credits, while others will simply identify sustainability issues that additional research and innovation will help to address.
The Submission Guidelines provide detailed information on credit aims, criteria and compliance requirements and additional guidance, background information and resources. It is the main source of information on the technical requirements for projects pursuing Green Star certification.
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.Download the submission guidelines
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.
For portfolio ratings, bespoke scorecards will be issued to project teams upon project registration.
Updated on 08/04/2016 for the Green Star - Performance v1.1 release.
For all credits targeted, the project team must complete the credit's Submission Template. It specifies the information and narrative required to confirm that the project complies with the Compliance Requirements of the Credit Criteria. In the Submission Template projects are also required to provide details of the evidence included in the project's submission to justify the claims made in the Submission Template. Projects must submit these Submission Templates provided and are not permitted to use an alternative document.
Submission Templates are provided in MS Word format. Please note there are no automated or 'smart' features embedded within the Submission Templates. Project teams are to fill in and edit the Submission Templates to suit their responses within the shaded areas indicated within each Submission Template. Feedback on these templates are welcomed.
A zip file containing all submission templates for the Green Star - Performance rating tool has been provided for download below (Version 1.1). For details on when to use the Initial Certification or Recertification Submission Templates refer to the submission guidelines. Updated on 08/04/2016
The GBCA introduced Recognised Provider status to make the Green Star process simpler, faster and more consistent. Recognised Providers are validated for their ability to consistently deliver Green Star points, and are not required to provide as much documentation as outlined in the Submission Guidelines and Submission Templates.
A number of credits require additional calculations to determine the number of points awarded. For these credits, a Green Star – Performance calculator has been developed.

While the Rating Tool will be updated from time to time, project teams are only required to adhere to the Submission Guidelines for the rating tool that their project is registered under. If the project team chooses, a later version can be used. Project teams are not subject to clarifications or amendments made as part of a revision unless registered for that Rating Tool version.
Upgrading to the current version of the Green Star Rating Tool
If a project is registered under a previous version of the Green Star – Performance rating tool, the applicant may choose to formally update the version of the rating tool (e.g. move from version 1.0 to version 1.1), to achieve the project's certification. For additional details on this process, please contact the Sustainability Services team.
