Carlaw Park Redevelopment

Carlaw Park was the renowned home of rugby league in Auckland for many decades. However, it remained abandoned for 8 years after closing in 2002 due to health and safety reasons. The new development includes; Quest Hotel Apartments, 10,000 m² of office space, 450 m² of cafes and retail stores.

The Challenge

An effective green-field approach was taken, but such a large site required careful management to allow every stage to be built while previously completed stages were being occupied.

Buildings on the site were all new build with a design requirement being a minimum 4 star green building rating but with the target to achieve 5 star.

To achieve this rating requires commitment from the principle, design team, main contractor, sub-contractors, tradesmen and finally building occupants. Great care is required for materials and plant selection, manufacture, construction and commissioning as well as handover and maintenance to ensure sustainability targets are met.

The Solution

City Multi R2 Heat Recovery Systems were used throughout the site. These would mean that fresh, conditioned air would be provided to all areas, without high energy usage.

One of the key factors in ensuring a building is energy efficient is control. G50 central controllers were installed, with an umbrella TG2000 for overall control, energy management and maintenance operations. Finally, a BACnet interface system to the Building Management System has been used.

Ducted indoor units were installed in most office areas, giving some flexibility for the tenant fit out as the buildings became let. All condensing units were roof mounted to minimise ground level noise and visual impact.

There are two other buildings on the site, both fitted with City Multi VRF.
