in the future
Green Star is designed for future needs - not just today.
What's the difference between 4, 5 or 6 Star Green Star?
After undergoing rigorous testing by an independent assessor, a development will be awarded a rating – either Best Practice (4 Green Star), Australian Excellence (5 Green Star) or World Leadership (6 Green Star).
Why should I choose a Green Star place to live?
How do I get a Green Star rating?
Achieving a Green Star rating is a big commitment and can only be achieved by registering your projects with the Green Building Council of Australia.
Steps must be taken at the earliest stage of a project, with the developer or builder demonstrating that they have met a range of best practice benchmarks for sustainability in order to achieve the rating.
Each development is different but some of the items assessed may include energy and water efficiency, how the building or community is designed to make the best use of its natural surroundings, the quality of the indoor environment, such as natural light and ventilation, and how waste is recycled and managed.
What Green Star rating tools can I choose?
There are currently four types of rating tools to choose from:
Green Star – Design & As Built
Green Star – Design & As Built assesses the sustainability outcomes from the design and construction of new buildings or major refurbishments, across nine holistic impact categories
Green Star – Communities
Green Star – Communities assesses the planning, design and construction of large scale development projects at a precinct, neighbourhood and/or community scale. It provides a rigorous and holistic rating across five impact categories.
Green Star – Performance
Green Star – Performance assesses the operational performance of buildings across nine impact categories.
Green Star – Interiors
Green Star – Interiors assesses the sustainability outcomes of interior fitouts across nine holistic impact categories.
You can find out full details on each of the rating tools by downloading the submission guidelines. 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.
What types of homes can achieve a Green Star rating?
Apartments and town houses:
Apartments like One Central Park in Sydney, which has been named the world’s best tall building, and Forté in Melbourne are just two examples of the apartments around Australia with Green Star ratings. Town houses – like the Prince’s Terraces Adelaide – can also gain the Green Star tick of approval, but individual freestanding homes are not yet able to be rated. Watch this space in the future!
Green Star communities:
Master-planned communities – like Aura on the Sunshine Coast, which will one day have its own postcode, and the carbon neutral Barangaroo South in Sydney’s CBD – can achieve Green Star ratings. If your community has a Green Star rating, this means the design of the community is sustainable – but that does not cover each individual home within the community.
Green Star retirement living:
If your retirement village has the Green Star seal of approval, you know your entire village has been assessed and meets Green Star’s best practice benchmarks. From the quality of the common areas to the design of parks, walking paths and connections with the broader community. The rating is for the whole retirement village, not individual homes.
