Green Star overview

What is Green Star?

Green Star is a comprehensive, national, voluntary environmental rating system that evaluates the environmental design and construction of buildings. With more than 4 million square metres of Green Star-certified space around Australia, and a further 8 million square metres of Green Star-registered space, Green Star has transformed Australia's property and construction market.

Green Star was developed for the property industry in order to:

Establish a common language;
Set a standard of measurement for green buildings;
Promote integrated, whole-building design;
Recognise environmental leadership;
Identify building life-cycle impacts; and
Raise awareness of green building benefits.

All you have to do is say 'Green Star' and set a star level, and everyone nods...one sentence to communicate a level of aspiration across half a dozen or more disciplines: that's pretty fantastic.

What are the Green Star Categories?

Green Star covers a number of categories that assess the environmental impact that is a direct consequence of a projects site selection, design, construction and maintenance. The nine categories included within all Green Star rating tools are:

Management
Indoor Environment Quality
Energy
Transport
Water
Materials
Land Use & Ecology
Emissions
Innovation

These categories are divided into credits, each of which addresses an initiative that improves or has the potential to improve environmental performance. Points are awarded in each credit for actions that demonstrate that the project has met the overall objectives of Green Star.

Once all claimed credits in each category are assessed, a percentage score is calculated and Green Star environmental weighting factors are then applied. These environmental weighting factors vary across states and territories to reflect diverse environmental concerns across Australia. Read more about the Green Star rating calculation.
