Degree of Freedom participated on the winning team for a new secondary school by the river Akerselva in Oslo. The proposal was made in collaboration with Ola Roald Arkitektur and contractor NCC, and others, and was inspired by the industrial history of the Sagene district. Degree of Freedom has been the structural engineer for the project during competition, preliminary and detailed design stages, including follow-up during construction.
The school, approx. 9000m2, will accommodate 540 pupils and will be a state-of-the-art building with strong technical and aesthetic qualities and high environmental ambitions.
In addition to providing modern education facilities, the building aims to become a meeting arena for culture, sports, and leisure activities for the local community. The project includes a sports hall, green roof terraces and extensive outdoor facilities.
Oslo Municipality places high climate and environmental demands on its projects and the Bentsebrua school will be certified BREEAM-NOR Excellent. To achieve the building’s ambitious environmental objectives the school will, for example, feature solar panels and be built with a large amount of timber in its interior and include a sedum roof.
The project will select machines and materials during the construction works to achieve a 40% reduction in carbon emissions compared with a standard reference project. The school will essentially be a zero-energy building when it is delivered.
The building has a total of four storeys, with two of them being partially belowground level. The wide range of materials accommodates different design demands. Glulam timber and CLT slabs fit well with a typical classroom span of 7m. The steel trusses over the sports hall are required for the 24m span. Structures below ground are reinforced concrete, both in situ and precast elements.
