Designed as Oslo’s new main library, Bjørvika is home to over 450,000 books, plus a recording studio, cinema and 3D printer. The main feature of this striking building is an atrium that spans six storeys and is flooded with light.
In order to ensure daylight penetrates deep into the building, the architects decided on a roof glazing concept including 440 square metres of OKATECH insulating glass. The shimmering aluminium inserts between the panes provide an unmistakeable finishing touch. The triple insulating glass also ensures both heat protection, as required across Scandinavia, and solar protection, with a U-value of 0.9 W/m²K and a g-value of 21% respectively.
Due to the typically low position of the sun at this latitude, the architects decided on a wider mesh for the asymmetric OKATECH metal perforation.
The result is a unique interplay of light and shade, depending on the angle of sunlight. At the same time, the structure of the mesh interrupts the rays of sun entering the building, thus providing dazzle-free daylight and a pleasant reading experience for visitors to the library.
