The upgrade has turned Lysaker Torg from the 80s into a modern and environmentally friendly landmark

The 1983 building has undergone an extensive upgrade that has involved demolishing the top floor, then building on two new floors. The solar cells on the roof provide green electricity to the public areas of the building.

“Now this magnificent, 40-year-old building is getting the upgrade it deserves. We are proud that the result is an environmentally friendly, modern building with good facilities for the six tenants who live here,” says Hege Auråen, builders' representative and project manager from Realkapittel Uttveckling.

One of the first office buildings at Lysaker

Lysaker Torg 6-12 was in its day one of the first office buildings to be built at Lysaker. The building was completed in 1983. In the past two years, the building has undergone an extensive upgrade that has involved demolishing the top floor, then building on two new floors, in addition to renovating the second to fourth floors. The result is a significantly more sustainable building that is one floor higher. The crowning achievement of the work was recently commissioned: a photovoltaic system that provides green electricity to the public areas of the building, provided by Sunday Power.

Owner, contractor and tenant with environmental focus

Lysaker Torg 6-12 ANS is the developer for the project, which in turn is owned by Scandinaviegaarden, Farvatn Capital and Backe Eiendom. The environmental focus has been central from the start of the project.

“The building will be BREEAM Very Good certified, while existing buildings will be BREEAM-in-Use certified,” says Stig Blokkum, General Manager at Lysaker Torg 6-12 ANS.

“Rooftop solar cells are a positive contribution to the environmental profile of the building,” he adds.

Backes new head office

Backe Stor-Oslo has been the contractor for the project, in addition to the fact that at the end of the year Backe moved its head office to the top two floors of Lysaker Torg, and thus is also a tenant.

The fact that they now also reside in the building they helped to rehabilitate and develop, they see as positive.

“Lysaker Torg 6-12 fits well into our strategy to increase our activity within the rehabilitation and development of existing buildings,” said Arne Landmark, CEO of Backe Stor-Oslo, in a press release.

“We have a strong focus on climate and the environment in our operations, and the environmental focus should also be reflected in our own office spaces. With the solar system in place, we also get to use sustainable solar power”, says Eirik Strand, General Manager Backe Eiendom.

Solar cells with significant CO2 savings

The solar photovoltaic system supplies the building with renewable energy to the public areas, which provides a CO2 saving of over 50,000 kg of CO2 per year. It provides a greener building, and is positive for both the building owner and the tenants in the building.

“We are impressed with the newly renovated building, and how they have managed to maintain some of the original qualities and turn it into a modern, significantly more environmentally friendly building. The property is emerging as a new landmark at Lysaker, and we are grateful to be able to work with forward-thinking players such as RealkapitalDevelopment, Farvatn Capital and Backe on this project,” says Rikard af Ekenstam, CCO of Sunday Power.
