7 March 2012 – The Green Building Council of Australia will restrict Green star design ratings from 1 January 2013 to two years after a building’s completion instead of the present unlimited time, in order to bolster the system.

GBCA’s executive director – Green Star, Andrew Aitken, speaking at the Green Cities 2012 conference in Sydney on 6 March, said stakeholder research found that one of the best ways to reinforce the value of Green Star was to place an expiry date on the design ratings.

This new policy will apply to any project registered for a design rating from 1 January 2013 irrespective of the rating tool used.

Mr Aitken said many building projects are promoted as Green Star-rated buildings long after they have been built despite having no certification that demonstrates the Green Star design was reflected in the construction or in the performance of the building.

“This has created some confusion in the marketplace. By limiting the length of time that building projects can market a Green Star – design rating, we will strengthen the robustness of the Green Star rating system and ensure that project teams that achieve As Built and future Green Star performance ratings are recognised and rewarded,” he said.

Mr Aitkin said the new time restrictions had already received positive support from industry.
