Dunedin International Airport Groundwater Heat Pump Energy System
MWH New Zealand

MWH New Zealand’s groundwater heat pump energy system has significantly reduced Dunedin International Airport’s operating costs, and enhanced the environmental comfort of those working in and using the airport’s refurbished and extended terminal building.
This project is an excellent example of using known technologies and off-the-shelf equipment in innovative ways to create a highly successful and integrated system design.

The groundwater heat pump system operates in challenging climatic conditions, where external temperatures can range from about -9°C in winter to about 30°C in summer. However, interlinking various control systems gives high energy efficiency and ensures the airport’s environmental comfort levels remain acceptable.

The airport also reports operating cost savings of $70,000 per year, savings that it expects will be ongoing.

The judges were impressed with the way MWH New Zealand’s project team developed a thorough understanding of the building’s energy usage and were able to use standard equipment to tailor an integrated control system to achieve the required solution.
