Green Star FAQs

FAQ F-00278
What is the process for upgrading my project from Design & As Built to Green Star Buildings?

The Upgrade Process:

1) Reach out to the GBCA and let us know that you are interested in upgrading to Green Star Buildings. The Market Engagement team will then request you submit further detail in an Eligibility Query through the GBCA online portal.

2) As an earlier version of the certification agreement was executed when the project was registered, the project Applicant will need to execute a new certification agreement (Version 4.1). This includes key clauses relating to Green Star Buildings and the use of data. A summary of the main changes is provided below.

3) Submit a complimentary Technical Question to the GBCA outlining all previously submitted Eligibility Requests or Technical Questions and request that they be reviewed for compliance under Green Star Buildings. Once the assigned Technical Coordinator has reviewed and updated these responses, if required, they will be reissued to the project team. Note: if no Technical Questions have been lodged for this project, this step is not required.

4) Once the Eligibility Query is approved, the upgrade will be processed.

Climate Positive Pathway requirements:

Projects already registered under Green Star - Design & As Built (any version) that wish to change their registration to Green Star Buildings are subject to the 'Registering from 2020 onwards' requirement regardless of when they update their rating tool. They are not subject to the 2023 requirements.

However, those upgrading are still subject to the requirement that applies to all buildings under 'Certified after 1st January 2030, regardless of registration date'.
