The site consists of four buildings; home to the local Court House, a restaurant & bar, and two commercial office blocks. The land and property is owned by Ngai Tahu, one of New Zealand’s largest Maori Iwi.
The Challenge
Snowfall in Queenstown is guaranteed and frequent during the winter months, creating a huge demand for heat pumps and tempered fresh air. However, the equipment used must be able to perform when the conditions are icy outdoors.
The site consists of four buildings; home to the local Court House, a restaurant & bar, and two commercial office blocks. The land and property is owned by Ngai Tahu, one of New Zealand’s largest Maori Iwi.
The Solution
Queenstown was a perfect place to demonstrate unique, New Zealand first products such as Zubadan Condensers, and AHU controllers in place of electric elements tempering fresh air systems.
The complex has been fitted with a total of 630kW of Mitsubishi Electric VRF and split systems. Added to this, Building 1 houses BDT’s very first set of Zubadan outdoor units, and AHU controller.
The building 1 fresh air system proved to be very successful demonstrating good energy savings, with Building 4’s AHU electric elements likely be replaced by a DX coil in the existing AHU, connected back to a set of Zubadan condensers in the near future.
