Québec actively reduces its CO2
July 11, 2018
Climate action undertaken by airports in the North American region continues to step ahead. For instance, Canada’s Québec City Jean Lesage International Airport achieved a successful upgrade to Level 2 Reduction of Airport Carbon Accreditation. We bring you their 3 most impactful initiatives that helped them start actively reducing their CO2 footprint.
1. The airport is effectively recovering heat from the screw chiller and uses it to supply the hot water loop.
This measure considerably reduces the amount of natural gas used for heating since heat released by the condensers of the screw chillers is injected into the hot water system when there is a cooling request together with a heating request (decrease of 586 tonnes CO2).
2. The heat is also recovered from stale air produced by heat wheels.
This measure makes it possible to capture the heat of the exhaust air and transmit it to the fresh air entering the terminal. Not only do the heat wheels recover the sensible heat, but they also recover latent heat, the humidity in the air, which saves heating and humidification. This measure allows for a decrease of 228 tonnes of CO2.
3. The airport is also using geothermal energy.
Geothermal. It is important to point out that geothermal energy, including the heat recovery of screw coolers, allows to substitute about 85% of the required heating energy and 78% of the cooling energy. Thanks to this measure the airport can save up to 356 tonnes of CO2 per year.
We keep our fingers crossed for other ambitious projects aimed at CO2 reductions carried out by Québec City Jean Lesage International Airport.
