Andrew Aitken, Green Building Council of Australia (GBCA) green star executive director, announced the introduction of time restrictions to the Green Star – Design rating, from January 1, 2013.

This new policy will apply to any project registered for a Design rating from 1 January 2013, irrespective of the rating tool used. The 24-month time restriction on Design ratings will not apply to projects registered before 1 January 2013.

Aitken says the ‘Design’ rating is seen as a promise within the industry, which then provides the groundwork for a Green Star – As Built rating.

“The As Built rating demonstrates that this promise has been delivered in construction, which in turn provides the foundation for an ongoing assessment of the building’s performance in operation,” Aitken says.

“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.”

“The industry’s leaders have been following up their Green Star – Design ratings with As Built ratings for some time, proving that they can deliver on the promise. Our new policy is a natural step towards greater transformation of the industry.”

In other Green Star news, the 5 Murray Rose development - the first stage of GPT’s $200 million Murray Rose Business Park - achieved the 6-star Green Star, Office Design v2 rating.

The 5 Murray Rose development features the largest solar installation in an Australian commercial building of this scale. This system will contribute 25 percent of the base-building’s peak load.

Michael Cameron, GPT’s CEO, says in 2011 GPT avoided $15.9 million in costs by reducing energy, water, and waste to landfill, compared to GPT’s 2005 baseline.

Sustainable design features of 5 Murray Rose include: 

  • 125kW rooftop solar system providing both a lower carbon solution and reducing peak capacity on the local infrastructure 
  • Chilled beams 
  • 100 percent outside air with 50 percent improvement on minimum ventilation rates 
  • Efficient facade design incorporating high performance glazing with external shading designed to minimise heat load and restrict glare, while providing good external views and daylight access 
  • Cyclist facilities for 10 percent of building occupants as well as visitors 
  • 25 percent of car spaces provided for small cars 
  • High efficiency T5 office lighting 
  • Run around coils for heat recovery and preheat of dehumidified air 
  • High efficiency chillers in series with excellent part load performance


Cameron says the development’s environmental initiatives, the partnership approach of GPT and the options provided by Sydney Olympic Park, were critical in the decision by the Lion Group to lease the whole 12,000 sqm of 5 Murray Rose.
