World’s tightest house built in Bristol Bay

 

Bristol Bay Campus Assistant Professor Tom Marsik and Kristin Donaldson set the new world record for the tightest residential building, according to the World Record Academy, for designing and building an extremely energy efficient house with the air-tightness of 0.05 air changes per hour at the differential pressure of 50 pascals. The world’s tightest known residential building was modeled after the Passive Office, a student-built experimental structure developed by the UAF Bristol Bay Campus Sustainable Energy Program.
