More daylight in the basement workshop
As part of the conversion of the elementary school, existing basement rooms were converted into classrooms. This raised the question of daylighting. Originally, excavations were planned on the north side to create two atriums. However, the necessary dimensioning of one atrium did not harmonize with the existing architecture of the staircase: the parapet around the atrium would have cut off almost half of the staircase. The solution was found with the mirror shafts from Heliobus. The workroom is supplied with sufficient daylight without any loss of space outside, i.e. the existing architecture can continue to be used optimally. The daylight supply via the mirror shafts could also be guaranteed more cost-effectively than by excavating the atrium.
