5 Martin Place the big winner at Property Council Awards

The refurbishment of Sydney’s 5 Martin Place has taken out the Development of the Year and Best Sustainable Development – Existing Buildings gongs at this year’s Property Council of Australia / Rider Levett Bucknall Innovation and Excellence Awards.

Dexus and Cbus Property were also presented with the Best Office Development award for the heritage restoration project, which Property Council chief executive Ken Morrison said “delivered one of the most inspired and innovative commercial workspaces in Australia”.

To protect the building’s heritage, the new commercial office had to be cantilevered over the existing building.

Even with this complex engineering feat, the building has still managed to be a sustainability outperformer, with 5 Star Green Star Design and As Built ratings and a 5 Star NABERS rating.

During construction 95.7 per cent of demolition and construction waste was recycled, and the retainment of existing facade and structures reduced the need for new steelwork, avoiding 5800 tonnes of CO2 emissions.

Materials like marble panelling and timber doors were also salvaged to be used in the new design.

Wellness has also been a key component, with at least 150 per cent more fresh air provided than required under the Australian standard. There is also more than 200 bike racks and associated end of trip facilities, including a bike repair service.

“5 Martin Place demonstrates how older buildings can be upgraded to meet new sustainability standards,” Mr Morrison said.

“And by breathing new life into the streetscape below, and investing in public art, Dexus and Cbus Property have enhanced one of Australia’s most important gathering places.”

Floth wins sustainability gong for new building

Floth’s Fortitude Valley office in Brisbane took out the Best Sustainable Development – New Buildings award.

The building, 69 Robertson Street, was the first to achieve a 6 Star Green Star Design & As Built rating, first to get a 6 star NABERS Indoor Environment rating, and first to meet ASBEC’s zero carbon definition.

“Floth has combined the world-leading with the practical to deliver a building with a swag of sustainability ratings,” RLB Queensland managing director David Stewart said.

Energy modelling has predicted a 53 per cent reduction in operational carbon emissions from façade and integral building services improvements at the building.  A 15-kilowatt solar system has further offset 28 per cent of the building’s operational energy, cutting greenhouse gas emissions by more than 19 tonnes a year, with additional emissions offset with GreenPower.

Rainwater is collected on the building’s roof and stored in a 15,000-litre tank. Together with other water-saving measures, the building uses 75 per cent less than a standard office building.
