Alaska Airlines hangar, Anchorage, Alaska

To replace an aviation hangar built in the 1950s, McCool Carlson Green Inc. designed a 100,000-square-foot hangar, more than twice the size of the original building. The maintenance and engineering hangar can house two aircrafts. It is LEED certified and designed to meet Alaska Airlines’ fleet additions for the next 30 to 50 years.

Jason Gamache, principal architect and director of sustainability at McCool Carlson Green, says, “One of the challenges with hangars or any kind of shop is that a large portion of your building is an opening. In this case, we have a giant 286-foot-wide by 47-foot-tall door that is a giant puncture in your envelope. Once we got the [insulated metal panels (IMPs)] on-site, it was very easy to install the panels and almost instantly have a building enclosure. Any work inside the building, like painting or concrete work that is temperature-sensitive, is scheduledependent on us being able to close the building.”

The exterior was constructed with more than 72,000 square feet of IMPs. Whalen Construction Inc. installed Kingspan Insulated Panels Inc.’s KS Micro-Rib IMPs in custom blue to match Alaska Airlines’ branding colors. To minimize waste, Whalen Construction used metal panel scraps to build a parapet for a parking structure.
