Our built environment is currently the world's single largest contributor to greenhouse gas emissions, it consumes around a third of our water, and generates 40 per cent of our waste.
Launched by Green Building Council of Australia (GBCA) in 2003, Green Star is Australia's largest voluntary and truly holistic sustainability rating system for buildings, fitouts and communities.
Green Star aims to transform the built environment by:
Green Star uses a robust, transparent and independent assessment process, and projects that certify can proudly display the Green Star Certification Trademark. Only projects that we have certified can claim to achieve a Green Star rating. Projects that claim to meet the requirements of Green Star but are not certified are potentially in breach of trademark rules and may be accused of ‘greenwash’.
We operate a quality management system which complies with the requirements of ISO 9001:2015 for the development, upkeep and delivery of Green Star Certification.
Green Star assesses the sustainability attributes of a project through impact categories. Each category groups a number of issues related to a certain sustainability impact; these are known as ‘credits’.
A credit addresses an initiative that improves or has the potential to improve a project’s sustainability performance; each of these initiatives is a criterion. Credits are weighted in relation to each other by varying the number of points available. Each credit defines a clear outcome that a project must meet. Where the outcome is verified to have been met, a project will be rewarded with the relevant available points.
Once all credits are assessed, the total number of points achieved is compared against the available points in the rating tool and a certified rating is awarded.
Certification identifies projects that have demonstrated the achievement of a specific level of sustainability. The rating describes the sustainability attributes of the project in terms that are widely understood and accepted.
Certify the design and construction, or major refurbishment, of a building.
From office buildings to local libraries, schools to master planned residential communities, Green Star has shaped the development of a broad range of projects. We have issued more than 2,800 Green Star certifications.
