The new building offers around 8ʼ000 square metres of flexibly usable rooms, a public library, a club and a concert hall for 280 guests. The foyer as the central building element develops cascade-like over all floors and connects the different functions with each other. Both the light and the acoustics are integrated into the rib-like structured concrete soffit. The light line as the basic lighting element follows parallel to the rib structure. The density of the light lines reacts to the type of use and the required illumination level. In the workspaces, the light lines are placed centrally in the window axis and reproduce the building grid. The goal of low power consumption for artificial lighting with very good colour rendering quality is achieved through the use of high-quality LED luminaires.
