ASB North Wharf

Located on the Viaduct in the recently developed Wynyard Quarter, ASB’s new head office proudly displays its services for all to see and has incorporated them as a dominant architectural feature within the space.

The energy efficient complex planned to reduce operational costs through intelligent design including the tailored heating, ventilation and air-conditioning systems.

The open-plan, activity based design of the building, was well suited to a mixed mode building that combines a displacement air-conditioning system with opening windows and a roof mounted funnel that induces air movement through the building.

This means the HVAC systems installed will only operate for approximately 60 percent of the time resulting in a sizeable 40-50 percent reduction in energy consumption.

Aquaheat's expertise and experience were put to good use for the execution of such a complex commercial build, where the majority of spaces have no ceiling and the building services were on display and needed to be installed to achieve a high standard of finish.

A unique example are the main supply air ducts that drop through the central atrium that have no visible means of supports, but achieve the required seismic ratings using a bespoke designed internal structure.
