Deichman Bjørvika / Oslo Public library

Project description

Deichman Bjørvika / Oslo Public library is built according to ambitious environmental standards. The library has high architectural qualities, and is functional and innovative in its use of future-oriented climate solutions. The new library opened to the public in June 2020.

The library is a five-storey building. The architectural concept is based on a large, central, continuous space that stretches up through the storeys. The first, third and fifth floors have mezzanines. A cinema, auditorium and open and closed storage are located in the cellar. The building also contains a canteen, restaurant, offices and various technical spaces. The library reaches many user groups through new technology and new services, and has a special focus on children and the young. Active culture and knowledge sharing are prioritized in order to inspire positive experiences and learning.

The library opens out to the city with entrances to the west, southeast and north. From each entrance visitors encounters diagonal light shafts that facilitate contact with the interior of the library. The light shafts cross each other higher in the building and create a large internal and unifying atrium. The façades are a combination of transparent windows and translucent walls. Outwardly the library presents itself as light and open. In the evening the light comes through the façade and gives glimpses of the rooms and activities inside.

Low carbon strategies

Deichman Bjørvika / Oslo Public library is planned according to FutureBuilt criteria of at least a 50 percent reduction of greenhouse gas emissions compared to today´s standard. The pre-project calculations showed a combined reduction of emissions of 69,8 percent.

The library fulfils passive house criterias according to Norwegian Standard 3701. The building has a compact form. Ventilation is supplied via the floor structure in the second to fifth storeys, thus reducing the need for fan energy. Since ventilation air is distributed along the concrete in the floor structure, the thermal mass of the building is utilized and temperature fluctuations are reduced. The same is true for the extensive use of exposed concrete ceilings. The concrete floors are cooled with built-in warming and cooling pipes in the concrete of the roof and floor (TABS). The system is effective and allows ventilation air quantities to be reduced. Automatic external solar screening is used to reduce the building`s cooling needs, and the use of energy-efficient IT equipment will be required.
