A Metricon home

Metricon, Rawson Homes and Stockland are among the home builders signed up to pilot the Green Building Council of Australia’s new Green Star rating tool for homes, currently out for consultation.

Residential has long trailed other asset classes on sustainability, which is why homes are the “the next logical step” for the Green Star treatment.

The GBCA is getting closer to releasing a Green Star rating tool for homes, with a new draft standard for new single family homes designed and built by volume builders open for consultation.

On Thursday, the council also launched a strategy that outlines the steps required to release an effective tool to market.

“The release of this strategy now builds on the extensive consultation we have already undertaken and enables deeper engagement with industry and government to seek further feedback,” GBCA chief executive officer Davina Rooney said.

A key piece of work in the strategy has been identifying what makes a home sustainable.

At a bare minimum, a home that passes muster will need to be healthy and safe for occupants, resilient to climate change, and net zero, which means it must be energy efficient and powered by renewables.

The industry body has also detected the key players, which most importantly includes future homeowners and volume builders, but also “banks and insurers and supported by developers, government, product manufacturers and professional services.”

Getting volume builders on board is critical because they can drive industry transformation at scale.

“We believe early adoption of this approach by volume builders will help educate and encourage similar innovation across the broader building industry,” the strategy states.

The next step is piloting the standard, with Chatham Homes, Delos, Development Victoria, HEZ Development, Ingenia Communities, Metricon, New South Homes, Rawson Homes and Stockland already committed to a trial.

Stockland chief executive officer communities and GBCA director, Andrew Whitson, said that the initiative represents a “great opportunity for us to take-stock and plan for the challenges and opportunities in front of us.”

“The current COVID-19 crisis has highlighted for many of us the importance of safe, healthy and resilient homes and the benefits of living in sustainable and connected communities”, Mr Whitson said.

Healthy home technology company Delos, which is the creator of the International Well Building Institute that created the WELL Certification program, has also signed up as a pilot program partner.

“Our involvement with the program focuses primarily on improving the wellbeing of occupants by optimising key elements in the indoor environment such as air, light and water,” Delos Australia general manager Anthony Scarff said.

“The new standard has clear benefits for new home buyers and will serve as a vehicle to enhance the health of occupants living in certified housing for generations to come.”

  1. When is GBCA likely to release home Green Star rating tool?
    It would be interesting to find out the energy, HVAC, electrical, fire, hydraulics, renewables and sustainability design and implementation requirements to achieve GBCA Green star rating for homes. I am passionate about sustainability, we operate in the home automation industry

  2. Great initiative GBCA. This is a benchmark for signiticantly improved performance in our housing stock and an independently assessed certification. Well done

  3. Lets hope that for many reasons the size & density of housing will improve along with sustainability. Just look at the South West Growth area, in Sydney areas of Oran Park & surrounds, EPIC FAIL.
