GREEN STAR Rating System (Australia)

About - Tools - Categories - Calculation GREEN STAR
The Green Building Council of Australia (GBCA) has developed a national environmental rating tool for buildings called the ‘Green Star’ rating system. The tool rates a building in relation to its management, the health and wellbeing of its occupants, accessibility to public transport, water use, energy consumption, the embodied energy of its materials, land use and pollution.
Green Star aims to assist the building industry in its transition to sustainable development.

The Green Star environmental rating system for buildings was created 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
· raise awareness of green building benefits.

There is a suite of Green Star rating tools for commercial offices at all phases of development - design, construction, and operations. Projects are evaluated against eight environmental impact categories, plus innovation. Within each category, points are awarded for initiatives that demonstrate that a project has met the overall objectives of Green Star and the specific criteria of the relevant rating tool credits. Points are then weighted and an overall score is calculated, determining the project's Green Star rating. Green Star rating tools use Stars to rate performance:

· 4 Star Green Star Certified Rating signifies 'Best Practice'
· 5 Star Green Star Certified Rating signifies 'Australian Excellence'
· 6 Star Green Star Certified Rating signifies 'World Leadership'
