Bayreuth Youth Hostel

The new building of Bayreuth Youth Hostel has a star-shaped ground plan with a central foyer and three building wings extending from it over two storeys.

The supporting structure of the building consists of a hybrid wood-concrete construction. For the internal parts of the supporting structure, such as corridor walls and ceilings, the material concrete is mainly used. The external parts of the supporting structure, in particular the façade and roof structure, but also non-load-bearing room partitions, are executed as a timber construction. Highly heat-insulating wooden panel elements are provided for the timber construction walls. The targeted use of these materials leads to an optimal building physics behaviour with heat-insulating components without thermal bridges in the area of the building envelope and sufficient storage mass inside the building.

The construction for the sloping and curved roof is also made of wood. For the wooden roof construction, different structural variants have been examined geometrically and mathematically. Parametrically programmed component geometries in various variants were displayed and evaluated. A construction was carried out in which the girders rest on the outside and inside of the walls or along the ridge line and roof opening on a spatial truss girder. The rafter level consists of a carrier mesh, the lower carrier panel of which is designed with parallel chords and the upper carrier panel of which follows the curved roof surface. The beam panels, which are pivoted against each other, are connected at regular intervals by V-shaped posts and create a spatial load-bearing effect.
