EUNOMIA

Immediately after their success in Widen, the structural engineers and façade engineers of Lüchinger+Meyer, in collaboration with WALDRAP, achieved another remarkable competition result: in the open project competition for the new building of the Social Insurance Court of the Canton of Zurich (SVGer) in Winterthur, the team was awarded 3rd place. The buildings are to be integrated into the newly emerging “Justice Campus” north of the main train station. (Unfortunately we are not able to add another building block to the area in the direct vicinity of our project Social Security Court Winterthur).
The Greek goddess “Eunomia”, who personifies the legal order, served as a meaningful inspiration for the name of the project. Two structures characterize the design: the courthouse dominates the overall complex as a distinctive building in its own right, with a four-story extension alongside it. The jury praised the project as very carefully elaborated. “The clear urban arrangement as well as the internal organization of the spaces are convincing. The proposed static structure makes valuable contributions to energy, appearance and sustainability at the same time.” We are particularly pleased with the appreciation of the building’s ” well thought-out structural design.”

The basement and core of the main building consist of a reinforced concrete structure. A wood-concrete composite system was developed for the ceilings of the upper floors. The slender concrete slab lies on a wooden ribbed ceiling and is bonded to it by the glued-in perforated sheets. Beams are arranged in the longitudinal direction of the building, which carry the slab loads and transfer them to the columns. Both the beams and the columns are made of laminated timber. The ceiling system meets all fire and sound insulation requirements. By using the concrete slab, the ceiling mass can be thermally activated.
The façade is constructed of prefabricated, floor-to-ceiling elements with a thermally broken aluminium system. Triple insulated glazing with a low G-value was chosen for the ribbon windows, so that less passive solar energy enters through the insulated glazing. The horizontality of the ribbon façade is softened by delicate Brise Soleils, which are proposed as semi-transparent PV modules.

All submitted projects can be viewed in the context of a virtual exhibition.
