Child day care facility

The child daycare centre located in Frankfurt-Riedberg, Germany, was built according to passive house standards and is the result of a design competition for modularly constructed daycare centres. The two-storey building has a rectangular floor plan and is surrounded by a steel balcony frame, which complies with high structural fire protection requirements. The modular and entirely prefabricated internal timber structure consists of timber frame walls, downstand beams and hollow core slabs. The floor slabs were designed as horizontal diaphragms, which transfer the horizontal loads to the timber shear walls and down into the ground. The building is supported on a raft slab foundation. The lowest visible layer of the timber floor is designed as profiled acoustic ceiling orientated to the direction of the span. In the centre of the extensive green roof is a square sky light, which is supported by glulam beams.
