To allow natural light to enter the oﬃce corridors, the fecowand solid wall is equipped with fecostruct frameless skylight glazing, ﬂush with the surface on both sides, using the structural glazing method. The continuous glass ribbon visually detaches the non-load-bearing oﬃce partition walls from the concrete-core tempered reinforced ceiling. For sound absorption, the solid walls in the oﬃces are equipped with fecophon acoustic elements comprising 19-millimetre-thick MDF panels with horizontal slits 14/2 (two millimetre slit and 14 millimetre bar) for acoustic eﬀectiveness. The air is conducted between the offices and corridors with the wall-integrated fecoair overflow elements. In order to indicate that the meeting rooms are occupied, the outflow openings can be illuminated in red.
