New additions to Christchurch International Airport see a modern heating and cooling system utilising low temperature geothermal energy.
Christchurch Airport services almost six million passengers a year with an increase of 1.5 million forecasted by 2020.To accommodate all these passengers, replacement of the 50 year old domestic terminal and upgrades to the existing international terminal have been undertaken. Part of the upgrade is a state of the art heating and cooling system designed by Beca Ltd. The system’s design means that very little energy is wasted.
When ambient temperature permits, water from the wells is used to cool the airport with no aid from chillers. The 12°C water is pumped from the aquifer via boreholes to heat exchangers.
This cools the water in the loops which travel around the airport. CIAL is a CarbonZero business.
