A rating tool for new buildings and major refurbishments
Why Green Star Buildings?
Climate action, resource efficiency and health & wellbeing are key megatrends changing the world as we know it. More and more companies are committing to climate action, as investors, consumers and employees expect more from companies than ever before. It's imperative that the built environment responds to meet the challenges of our time, or risk obsolescence.
Launched in 2020, Green Star Buildings has been especially designed to meet the challenges of the next decade, delivering assets that don’t just meet the expectations of today, but are also future ready and will withstand evolving customer demands, regulatory requirements and increased scrutiny against greenwashing. The biggest overhaul of the Green Star rating system in over 18 years, Green Star Buildings has been embraced by industry with over 400 new buildings registering under the tool – the fastest uptake out of all Green Star rating tools.
Whether you’re a developer, occupier, investor or leasing agent, Green Star Buildings will help you stay ahead in a changing world. Discover how Green Star Buildings can help you today. Download a brochure below or email meteam@gbca.org.au to request a briefing.

Key features of Green Star Buildings
Help future proof your asset
Green Star Buildings is a holistic tool that extends beyond the environment to address the issues that will define the next decade of the built environment. The tool’s 8 categories enable owners and developers to act on the areas of sustainability that matter most, future proofing a building for the long-term.
A clear path to reach your decarbonisation goals
Green Star Buildings includes the Climate Positive Pathway* - a clear set of targets aligned with the IPCC recommendations to help you deliver a Climate Positive building that’s fossil fuel free, powered by renewables, highly efficient, built with lower carbon materials and offset with nature.
Access sustainable finance with ease
Any building that meets the Climate Positive Pathway automatically complies with the Climate Bonds Initiative, making attracting capital simpler than ever.
Fast, simple, streamlined reporting
Green Star Buildings has been specifically designed to align with leading frameworks, including the UN Sustainable Development Goals, GRESB, IPCC recommendations and the Task Force for Climate Related Financial Disclosure. The result? A project that aligns with expectations and makes the reporting process faster and simpler.

The Green Star Buildings - Apartments Pathway
The Apartments Pathway is a new set of requirements and targeted credits within the Green Star Buildings rating tool to help you deliver more sustainable multi-unit residential projects. For the first time, the pathway will offer independent unit-level certification, giving buyers, banks and tenants confidence that each home meets high performance standards.
The pathway is optional for Class 2 multi-unit residential projects including, build-to-sell, build-to-rent, affordable housing, community housing and mixed-tenure housing certifying under Green Star Buildings. It does not include student accommodation or hotels.
Any multi-unit residential project that is registered for a Green Star Buildings certification is eligible to use the Apartments Pathway. Applicants can opt-in to use the Apartments Pathway as part of their Green Star Buildings registration when completing the online application. For projects that elect to use the Apartments Pathway there are specific marketing rules outlining how this commitment can be communicated.
Yes. Projects that are already registered under Green Star Buildings may notify the GBCA that they intend to follow the Apartments Pathway by submitting an Eligibility Query via the Green Star Manager online portal. The GBCA will then confirm whether the project meets the eligibility criteria.
For the first time, the Green Star Buildings Apartments Pathway will allow you to receive a report that verifies that each individual unit, not just the building it is in, meets the requirements. This means you can provide more assurance than ever before to buyers or renters that the apartment is a great home, in a great building.
The Green Star Buildings marketing guidelines set out how to communicate that your project is targeting or has achieved the requirements of the Apartments Pathway.
No. Your certification fee for Green Star Buildings includes completion of the Apartments Pathway if you decide to opt-in.
The Green Star Buildings – Apartment Pathway v1 outlines the full credit requirements and can be accessed via the Green Star Resources Portal. Applicants and project teams are encouraged to familiarise themselves with the credit requirements. Our toolkit for industry summarises the benefits of using the pathway.
