Do you deserve a green star?

A number of projects, particularly commercial construction, have been rated in Australia, using a 'green star' rating system. This sounds good when someone tells you their project has rated six green stars, but what does it really mean?

The Green Star system is a system developed by the Green Building Council of Australia. It aims to rate environmental design and construction of buildings in Australia and is done in a voluntary, national and "comprehensive" manner. Within the Green Star rating tool there are nine categories. These are:

• management
• indoor environment quality
• energy
• transport
• water
• materials
• land use and ecology
• emissions
• innovations

Each of these categories are then divided into credits and a project assessed against the objectives of the categories and awarded credits within each category. These credits are then assessed as a percentage score, with a Green Star weighting factor then applied to then determine the building's overall rating, being four, five or six Green Stars. Six Green Stars indicates that the building project is considered as demonstrating 'world leadership' in environmentally sustainable design and/or construction.

Further information about the Green Star rating system is available on the Green Building Council's website.

How useful this is is potentially questionable, but at least there are some questions being raised about the efficiencies that can be undertaken both during design and construction within a commercial building development and hopefully this then transfers through to the building occupants and they continue to "capitalise" on the green savings the building can generate for them!
