the hall and equipment rooms. This means that no work is required on the high gable
walls of the hall, which simplifies the use of equipment on the construction site. Due to
the optimizations in the planning- and construction process, it was possible to complete
the hall within two years after the competition decision and commissioning. The lighting
of the two-bay hall is provided by glazing strips on both long sides. Louvre windows
rhythmize this in every fifth bay and provide natural ventilation. For heating the sports
hall, radiant ceiling panels are used, which, mounted at a height of seven metres bet-
ween the beams, enable maximum usable heat transfer. The radiant heat is perceived
as pleasant by the body and is absorbed directly; it continues the natural character of
the hall not only through the materials chosen, but also through the heat distribution
in the interior. The use of radiant ceiling panels means that no component needs to be
activated separately, enabling the large hall volume to be heated quickly and efficient-
ly. Other technical elements such as the ball-proof LED lights or the acoustic panels,
which are reduced to a minimum, blend into the intermediate fields of the supporting
structure and complete the appearance of the hall ceiling. The existing heat centre of
the neighbouring football hall with CHP and peak load boiler (gas) serves as the heat
source. The heat is transferred to the new central heating system via a local heating pipe.
A transfer station with a plate heat exchanger hydraulically separates the two systems.
The adjacent changing rooms with showers and toilets are supplied with heat by an
underfloor heating system. Two controlled air-handling units ventilate and exhaust the
changing rooms. The air is heated by a highly efficient heat exchanger. Thus, losses due
to air exchange are very low and moisture transport takes place in a controlled manner. Lageplan • Site view
