Vocational School Center Konstanz

The Zeppelin Vocational School and the Wessenberg School in Constance are being merged to form a joint vocational school centre. In addition to classrooms and common rooms, a cafeteria, a sports hall, several workshops, and rooms for the district media centre and the district archive are being built. The design of the new building complex comes from the Viennese Franz and Sue ZT GmbH, Werner Sobek is responsible for the building physics and the structural enginnering.

While the commercial part of the school, including the workshops, consists of a wide-span reinforced concrete composite construction, the ceilings of the central building and the commercial part are constructed using a wood-concrete composite construction. This is produced in prefabricated form, installed on the construction site and connected to the horizontal bracing of the ceilings with turnbuckles.

Climate-Friendly Building Physics and Structural Design

The roof structure of the sports hall consists of single-axis, approx. 30 m long glulam beams, the height of which is adapted to the force path. To increase flexibility, every second main beam is supported by glulam cross beams.

The vocational school centre’s energy efficiency and materials have been optimised with the aim of achieving DGNB Gold certification and funding from the federal funding programme for efficient buildings in the Efficiency House 40 category. In concrete terms, this means that the energy requirement is 40% of the legal standard. In addition to consultancy and design services in the areas of thermal insulation, energy efficiency, sound insulation and room acoustics, Werner Sobek carried out various simulations to determine the thermal comfort of the users and the sound propagation in the neighbourhood.
