The Zeil des Wissens is naturally lit with a glass roof. The four-storey interior facades are largely open to this communicative marketplace. Break-out rooms edge into the airspace as glazed cubes. The corridor glass walls of these group workrooms are designed as fecoplan all-glass constructions with floor-guided sliding glass doors. The rooms and offices are separated from the open learning landscape by fecofix double glazing and are transparent. The curved glass wall of the canteen, as flush double glazing which is 3.50 m high and horizontally divided at a height of 2.50 m, forms a single object solution and a special design highlight.
