Key projects | Closed Cavity Go to contents 50 K8 is a mixed-use office development that aims to boost the city of Stavanger's urban development. It will set new standards in the city in terms of sustainability – it is targeting BREEAM NOR Excellent and WELL Gold certification. Furthermore, it will provide a creative work environment for its occupants and users.

Staticus is responsible for designing, building and installing the façade for this tower. The façade design is a composition of slim vertical aluminium and glass panels that offer increased daylight to over 600 workspaces. Importantly, the façade is a closed cavity façade (CCF). Therefore, this project builds on our experience with CCF that we gained when successfully creating Northern Europe's first ever CCF for the VIA VIKA building in Oslo. However, the CCF for K8 posed some specific and new challenges. The biggest issue was finding a solution that works effectively while passing all of the planned tests for this project. This included air tightness (EN 12152) and water-tightness (EN 12154 and EN 12155) testing, as well as a special fogging test required for CCF. In 2022, all of these tests were successfully passed. Furthermore, a section of the CCF required a fire rating of EI120. Modular façade systems do not meet this rating, so the team worked hard to find an overall solution that meets this fire resistance requirement. There were also specific requirements and restrictions related to the colour, installation and transportation of the blinds. Through innovative thinking and teamwork Staticus was able to find an effective solution. The K8 project has also been noteworthy for Staticus because of innovations we have introduced to production design. K8 is the first project in which all information for production was delivered via model- based definition. This is a work in process, with some questions still being resolved. Despite the difficulties and a lot of time spent on creating a completely new workflow, we expect a great result that we can pass on to future projects. Staticus estimates to implement the project in 2023.
