Although Green Star tools are freely available for self-assessment, 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.
Green Star Certification is a formal process which involves a project using a Green Star Rating Tool to guide the design or construction process during which a documentation-based submission will need to be collated as proof of this achievement. The Green Building Council of Australia will commission a panel of third-party Certified Assessors to validate that the documentation for all claimed credits is in adherence with all of the Compliance Requirements outlined in the Technical Manual for the relevant rating tool.
