The video is a good promotion piece. But doesn't tell other professionals much about how the energy positive feat was achieved. I would like to know more about the life cycle cost calculations, the annual cycle of energy use, the thermal properties of the external enclosure, the air-conditioning etc.

Doors open to Powerhouse Kjørbo 


The first energy-positive building in Norway has opened for business in Sandvika, Bærum. The 5,200 sq m project involves the renovation of two buildings into a commercial entity that will generate enough energy within its anticipated 60 year life expectancy to cover the amount used to produce the building materials, construction, operation and disposal of the structure itself.

A team of seven companies worked in close collaboration to devise this first-of-its-kind scheme: Entra Eiendom; Skanska; Snøhetta; ZERO; Hydro; Sapa og; and Asplan Viak. Ståle Rød, Chairman of the Powerhouse consortium and CEO of Skanska Norway, explains: “As far as we know, this is the first building in the world that has been renovated into an energy-positive structure. It is the unique collaboration we have had from the very start that has made this possible.”

The pair of existing buildings date back to the 1980s and cover an approximate area of 5,200 sq m. The consortium have inserted the largest rooftop solar photovoltaic array in Norway, capable of generating over 200,000kWh per annum, alongside geothermal energy wells.

Consulting firm Asplan Viak has already moved into the building. The firm’s Managing Director, Øyvind Mork, comments: “Our ambition is to be the leading consulting company in the area of energy and environment, and I can’t imagine a building that better fits our profile. We are moving into the office building of the future - an energy-positive building with an excellent indoor climate.”
