The structure consists of 7 transversal timber arches, which are connected to concrete foundations.
The arches have a different shape to generate the volume of a soft curved structure. At one side of the structure there is a cubical technical building. At the opposite side there is an entrance area, which has a vertical façade.
The 7 arches are connected with 11 longitudinal ribs. These curved ribs connect all arches to the technical building. The steel profiles also act as bearing profiles for the ETFE foil cushions. Together with the Politecnico of Milano, architect Carol Monticelli, made a study on the different patterns and layers in order to reach the best results for the modulation of the shadow and the transparency of the material.
The ETFE cushions are 4 layer cushions. The upper and the lower layer have a thickness of 250µm each. The inner layers have 100µm thickness. The nominal pressure in the cushion system is 300Pa. In winter time this will be increased to 600Pa and in case of reasonable snow fall up to 800Pa.
A minimized attachment detail has been developed for the ETFE cushions. Perpendicular to the surface small steel plates are placed to which on either side the cushion is attached with a small extrusion profile. A soft gutter Is integrated in this connection detail to guide condensation water towards the lower ends, where it is further guided to the drainage system.
