In Kiel-Schilksee, a two-span sports hall was built to a low-energy standard, covering an area of around 22 x 44 metres. The supporting structure consists of an internal steel supporting structure with under-tensioned girders and an innovative cable system that relieves the load on the rigid girders and at the same time offers high material efficiency. This construction method reduces the dead weight of the structure and makes optimum use of materials. Isowall constructions with a metallic coating are used in the facade area, which both fulfil the fire protection requirements and offer excellent thermal insulation. On the northern long side, the hall was extensively glazed to optimise the use of daylight.

Environmentally friendly heat supply and state-of-the-art ventilation technology
A wood pellet heating system, which is characterised by its good climate balance and low pollutant emissions, is used to heat the sports hall and provide hot water. The energy-efficient system thus contributes to the environmental compatibility of the building. The heating system is supplemented by a ventilation system with heat recovery, which is suitable for passive houses, ensures constant air quality and enables considerable savings in heating costs by recirculating more than 80 % of the heat. The plant rooms also offer space for the future installation of a solar thermal system. In addition, the entire roof area is available for a potential photovoltaic system, which could further optimise the energy supply.
Room layout and equipment for versatile use
The sports hall can be divided in the centre by a partition curtain and can therefore be used flexibly. Changing rooms and sanitary facilities are located to the south and stand out from the main hall thanks to their striking choice of colours and materials. Side rooms in the basement provide space for sports and gymnastics activities as well as a pool area. A modern double sprung floor absorbs shocks and vibrations to reduce the strain on the athletes. A wide range of integrated and flexible sports equipment expands the offer and makes the sports hall a modern facility for various sports and training methods.
