It’s the latest “Powerhouse,” a name the architects at Snøhetta invented to describe super-efficient that generate power for the community around them. For most of us, life in the city of Trondheim, Norway, would take some getting used to. At 63 degrees north of the equator, it receives but five hours of daylight in the winter and a full 20 hours of daylight in the summer. Trondheim’s extreme seasonal shifts would seem anything but optimal for generating consistent solar power, but the global architecture firm Snøhetta just completed a building in the city that proves otherwise. The structure generates twice as much as it needs through the sun—enough to offset the hidden costs that are part of the building’s construction and eventual demolition. Its solar array is so productive, it works as a mini reactor for the city, providing excess to neighboring and electric transit.Read Full Story
