The rounded shape with two curvatures of this large roof covering a winter sports complex is suspended with a 120 metre span single arch provides the building with a powerful image and is an echo of the surrounding foothills of the Ore Mountains. The 1,000 millimetre tube supports a thin tubular prestressed lattice truss which creates an impression of a very subtle structure when seen from the interior of the roof vault. This slender solution is also economic both in terms of construction and minimisation of the heated space and facades surfaces. This contributes significantly to lowering future operating costs and to the protection of the environment.
