Energy lost every time the doors opened
In 2011, the Air Transat head office became the first Canadian building to earn LEED-EB Platinum certification. Striving for continuous improvement, in 2014 Air Transat mandated the firm Bouthillette Parizeau (BPA) to conduct an energy feasibility study for its Airbus A310, A320 and A330 maintenance hangar.
The study revealed that the shed's energy consumption was very high. In fact, just opening the main door for one minute would reduce the temperature of the entire building to the outside temperature. If it was -30°C outside, for example, you had to raise the temperature by 50°C every time the door closed.
“The goal was clear: not only did we need to cut down our energy consumption and GHG emissions, we also needed to improve employee comfort during the winter months. We had to come up with some creative efficiency measures to make it cost effective and comfortable,” said Geneviève Dubé, environmental systems and services advisor at Air Transat.
