South Australia Water Headquarters, Adelaide

The new South Australia (SA) Water headquarters in Adelaide is a showcase of sustainability; water, energy and waste have all been targeted to create SA’s first 6-Star Greenstar building. Completed in 2008 with a budget of $100m, the building uses 70 percent less water and produces 60 percent less greenhouse gas emissions compared with typical office buildings. The central stair installation, 25-meter long suspended stainless steel mesh with printed sections of the Murray River, provides inspiration and incentive to take the stairs rather than ride in an elevator.

Vipac’s Role: Vipac was engaged as the acoustic engineer for base building and fit-out, including architectural acoustics and noise and vibration control for all engineering services. Vipac also provided the wind assessment of the proposed site – pedestrian wind and wind-induced noise from the glass veil to the southern facade. The building features an under floor displacement air-conditioning system including economy cycle mode, involving ventilation of the building through a central 10-level high atrium. The atrium roof was constructed of air pressurised ETFE (the material used in the construction of the Beijing National Aquatics Centre, a.k.a. the Water Cube of the 2008 Olympics), which imposed a number of challenges to the acoustic design given the roof mounted services plant.
