ASB North Wharf, headquarters of ASB bank and the anchor project in Auckland’s Wynyard Quarter, was a first-rate example of flexible working spaces and sustainable design when it was completed in 2013. The building spans two sites, with a multi-level glazed walkway over a central public lane that provides access through to the adjacent Waterfront Theatre site.
The ‘Activity Based Working’ design presented a number of challenges that required performance based solutions. 15 individually themed, open areas were designed for flexible working also required a flexible evacuation design flexible to allow for the building’s occupants to move between floors. By utilising a performance based approach, Holmes Fire reduced the number of stairs required by a prescriptive solution, supporting the project’s objective to create an open and flexible layout. The evacuation plan also was designed to be flexible and utilise the open interconnecting stairs for egress in some fire scenarios.
Sustainability was also a significant factor that influenced the design and use of the building. The addition of a ventilating funnel and controlled internal shading have assisted in the reduction of the building’s energy use by 50% and resulted in the completed building achieving NZGBC 5 Star Green Star Rating for Office Design. While the ventilation funnel provided beneficial natural lighting throughout the building, Holmes Fire designed a smoke management system that not only aligned with the ventilation system but also avoided the need for a dedicated smoke control plant. A ‘hot smoke test’ was conducted by Holmes Fire following the completion of the project demonstrating the strategy for smoke movement in action.
