Thunder Bay Aiport

Thunder Bay, Ontario

The new building is three times the size of the former airport terminal, yet it consumes the same amount of energy as the old one.
According to Gerry White of the Public Works of Canada (PWC), "We were looking for the most high-performance fenestration system we could get because, at that time, Ontario Hydro had a rebate program. The Overall U-Value specified was 0.15 W/m². That's why Super Spacer® was in there—as another way of improving thermal performance.”
This was Kawneer's first triple-pane curtain wall system, which they went on to name their 7500 Series.
"It certainly is a very energy-efficient building and had to be to meet Ontario Hydro’s strict rebate criteria. Thermal scans were done up and down the building looking for hot spots, and they came out quite good. There was a lot of effort put into the specifications and design of that building,” White said.
