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.

• 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

- 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
