Green Star
• Objectives of the Standard
• Key elements of the Standard
• Challenges or costs associated with the Standard
• Comparability of the Standard
• Evolution of the Standard
Origin of the Standard
• Green Building Council of Australia (Lead Agency)
• Objectives of GBCA to promote sustainable development
and the transition of the property industry towards
sustainability by promoting green building programs,
technologies and design practices.
Origin of the Standard
• Green Star was created by GBCA for use in Australia to
evaluate environmental initiatives of design, projects and
/or buildings on a number of criteria including energy and
water efficiency, indoor environment quality and resource
conservation.
• Built from BREEAM and LEED with Australian adaptation.
How is it maintained/monitored
• Green star for the Convention Centres has been
developed as a design tool not an ongoing operational
tool and is still evolving.
• In Victoria and Australia other criteria are used such as
Green Globe, Resource Smart, Waste Wise, Water Wise,
and various Sustainability Victoria measures
Objectives of the Standard
• Establishment of a common language and standard of
measurement for green buildings
• To drive change in the building market by focussing on
those areas of environmental impact that are a direct
consequence of a building’s briefing, design , construction
and maintenance. i.e. those that can directly influenced by
stakeholders
Key Elements
• Nine separate environmental impact categories
Management, Indoor Environment Quality,
Energy, Transport, Water, Materials,
Land Use and Ecology, Emissions and
Innovation
Key Elements
Each Category is made up of credits
Each credit addresses a particular initiative
Points are awarded within each credit
A percentage score for the category is determined
An environmental weighting is then applied.

Key Elements
• The final green star rating is based on weighted
category scores and NOT the total number of
points
• These category scores are added together and the
maximum possible is 100 plus up to five additional
points for innovation
• Ratings range from one star to six stars. Only four
stars and above are eligible for certification.
• Five stars represents Australian Excellence
• Six Stars recognises World Leadership

FINANCIAL STUDY
GREEN STAR BENEFITS AND
SUCCESS
The additional capital cost of the 6 Star design solution created the following benefits:
-
Long term environmental marketing benefits (25 years)
A decrease in utility consumption generating savings of up to $400,000 per
annum, this equates to a saving of $8-$10m net present value over the 25
year term
The Green Star success is attributed to:
-
Dedicated resources – Client, Builder, Consultants, Architects
-
Active Senior Management of the process
-
Flat management structure
-
External peer review
Use Green Building Council of Australia resources
