18 June 2014 — Melbourne’s 171 Collins Street, a joint venture project by Cbus Property and Charter Hall, has been recognised for outstanding green building achievement by the United Nations Association of Australia.
The building, designed by Bates Smart and project managed by Brookfield Multiplex, and the first Premium Grade commercial building in Victoria to achieve a 6 Star Green Star – Office Design v2 rating, was awarded the Hanson’s Green Building Award at the UNAA World Environment Day Awards.
“Providing a healthy work environment for our tenants has always been a key pillar of our vision for 171 Collins Street,” Cbus Property chief executive Adrian Pozzo said.
“To be recognised in this way goes to the heart of what we wanted to achieve with this landmark project, and that is one of the best offices in Australia. Cbus Property has a strong commitment to sustainability across our portfolio, and this award reinforces that.”
The development comprises a new office tower with a high performance facade of glass panels featuring a ceramic frit, and a thermally enhanced separated curtain wall, which assists with reducing heat and glare. The tower is linked to the heritage Mayfair building, which was refurbished as part of the project, and has at its centre a nine-storey atrium clad in a cascading glass veil of more than 720 individual glass panels, which provides natural light for both the tower and the Mayfair building.
The project’s facade engineers and fabricators Yuanda and specialist facade consultants BG&E Facades invested considerable research and development into the methodology and materials for both the facade and the atrium to achieve thermally efficient and light-enhancing outcomes.
Construction focused on using recyclable materials including 90 per cent recycled concrete and 90 per cent recycled steel. In addition, 90 per cent of construction waste was recycled and a 60 per cent reduction in PVC use was achieved.
The Bates Smart design integrates large floorplates with an extremely energy-efficient and flexible under-floor air distribution system throughout. This system uses fresh air to ensure maximum comfort and indoor air quality for occupants. Low-VOC and low-formaldehyde emissions were also prioritised in terms of fitout materials.
Umow Lai provided the engineering consultancy for the mechanical, fire, lift, electrical and hydraulics systems, with sustainable aspects of these systems including an advanced rainwater and grey water reuse system; destination controlled lifts; highly optimised lighting design with extensive controls for occupancy and daylight harvesting; and energy efficient fixtures and fittings.
The building also includes 280 bicycle spaces, a dedicated bicycle ramp access separated from cars, change rooms, lockers, drying rooms, and an air compressor for pumping up bicycle tyres.
Since its completion in mid-2013, 171 Collins Street has been the recipient of several awards, including the International Property Awards (Asia Pacific) in May 2014, where it was judged the Best Commercial High Rise Development in Australia and was also highly commended in the Office Development Australia category. Its major tenant, BHP Billiton, took out the Best Office Interior Award for both Australia and Asia Pacific for the design of its global head office at the same awards.
171 Collins is 90 per cent leased, with BHP Billiton, Egon Zehnder and Evans & Partners having been in occupation since mid-2013. New tenants VicSuper and McGrathNicol have recently moved into the building and Wood Group PSN is scheduled to take occupation late 2014. The building is also home to Dolce & Gabbana’s first Australian flagship store, and to Supernormal, the newest restaurant and bar by chef Andrew McConnell.
“We are incredibly proud of this latest recognition, which cements 171 Collins Street’s position as a world leader in sustainable design,” Charter Hall Office Trust fund manager Craig Newman said.
“Combined with the International Property Award, 171 Collins Street is one of the most exciting and awarded buildings in Australia. It has delivered a new era in office design that combines the best in modern architecture and the greatest in sustainable innovations to deliver a truly revolutionary building.”
