This award is based on the environmental features of the design and will only be awarded if deserved. It recognises the relationship our man-made buildings have with the environment and responsibility we have as an industry.

With its curved roof, concrete glass reinforced concrete (GRC) soffits and fascia panels, sleek curtain wall façade, elliptical atrium, and large bunds, this building’s architecture stands out.
The Hawkins team knew that the curved roof with its GRC soffits and fascia panels would take time. The panels weighed 900kg each and needed to be lifted from above and attached to the structure prior to the roof’s installation. Recognised as a key risk, Hawkins formulated a construction sequence that allowed the project to get sufficiently weathertight early on, so internal fit-out could commence while work continued on the exterior.
As an integrated base-build and fit-out project, a calculated GreenStar assessment process tracked the design through all phases. This dovetailed with the contractor’s GreenStar quality administration processes. A federated BIM model helped influence design in areas such as solar performance, heating and cooling loads and volumes, and rainwater harvesting capacity. All material selections were reviewed and approved by a GreenStar consultant to assess their contribution to achieving the targeted GreenStar rating.
Sustainability was a major focus throughout this build.
The office building is connected to a solar system generating electricity from a solar array located on the roof of the neighbouring distribution centre. This is the country’s largest solar farm and generates enough electricity to meet the site’s needs, while sending extra back to the grid.
A federated BIM model assisted the team in evaluating and manipulating the sustainability performance, and to achieve targeted solar performance, thermal efficiency, and rainwater harvesting.
The project is currently being assessed for a Greenstar 6 rating.
