Christchurch Airport – Innovation and Aquifers

Christchurch Airport’s Ground Source Heating and Cooling

In 2011 a world class innovation in ground source heating was pioneered at Christchurch Airport - utilising the aquifers that flow beneath Christchurch to provide an artesian-based heating and cooling system.

This new system replaced the diesel boilers, reduced our carbon emissions and operating costs, and all while maintaining the integrity of our pristine aquifers. Leap ahead to 2019, further technological advancements have been made, and we have decarbonised the entire heating and cooling system.

Christchurch Airport is fully transitioned to ground source heating, and after only ten months have reduced our emissions by 791tCO2e.
