Snøhetta?s new office building in Norway will produce more energy than it uses
Ivar Kvaal
Snøhetta?s Powerhouse Brattørkai captures solar energy during long summer days and stores it for winter Trondheim, Norway, is 63 degrees north of the Earth?s equator. During the summer, daylight can stretch for 20 hours?in the winter, the sun peeks out for just four hours. Building an energy-efficient building in a climate of extremes is no small task, and yet, that?s exactly what Snøhetta has done with Powerhouse Brattørkaia, a recently completed office building in Trondheim.
Powerhouse Brattørkai is the northernmost ?energy-positive? building in the world. Snøhetta estimates that on average, the energy produced by the 193,750-square-foot building will more than double the energy it consumes daily, with any extra energy being stored and distributed to nearby buildings and transportation through a local micro grid.

The ambitious building has a slanted, pentagonal roof covered in solar panels. All told, the building is clad in more than 32,000 square feet of solar panels that generate around 500, 000 kWh a year. The energy generated during the long days of summer will be stored on site and used during the darker winter months.

Of course, an energy-positive building needs to do more than generate kilowatts?it also has to be efficient. Snøhetta designed the building to bring in as much daylight as possible. A circular cut-out allows light to stream into the interior. It also creates a light...
