The goal has been to build a school that uses little energy, thus meeting the requirements for a passive house level on the climate shell and that has integrated solar cells in the facade. Emphasis was also placed on the reuse of materials in the project.

About the assignment
Sofienberg School is a secondary school in the Grünerløkka district of Oslo and consists of two buildings connected by an intermediate building. The concrete building from 1970 was renovated on behalf of Undervisningsbygg Oslo KF and with Ola Roald AS as architect.
The 2,600 square meter building has been given a new facade that makes the building use little energy and thus meets the requirements for passive house level on the climate shell. The new facade modules have integrated solar cells on the south-facing facade, and a solar cell system has also been installed on the roof. In total, the ambition is that the solar cell system will produce around 40 MWh annually.
Description of the solution
In the project, exterior doors, gates, lighting, radiators and cable routing were reused in the renovated school building. Windows, doors and other materials were removed and reused in other projects.
A review of the entire building was carried out in connection with the facade rehabilitation, and materials that can be reused were mapped and registered and these were made available for reuse.
The most challenging part of the project was the short time we had to dismantle existing facades and install new element facades, while at the same time we had ambitious sustainability goals for reuse, solar cells and energy consumption. Multiconsult prepared 4 overall studies in an initial phase, prepared a preliminary project and in the detailed design phase designed, drew and described in an NS3420 description all the work to be carried out in connection with the facade rehabilitation. The project was carried out as a general contract, partly with the school in operation. Multiconsult has had all the consultancy services.
