The technical solution here is based on previous experience with large halls. All of the necessary features were realized successfully according to a low-tech concept. The interrelations of daylight and artificial light with ambient climate and acoustics influence people’s feeling of well-being in the Hall. The concept for the technological building systems takes up these relationships and integrates them in an interdependent manner, adapting their range of influence by modifying their dimensions or building in appropriate control mechanisms. A major goal in designing the systems was to save energy. This aim is achieved by minimizing the mechanical apparatus for ventilation, heating and cooling. The gigantic Hall is thus conceived as a solar-heated, naturally ventilated sub-climatic area, a multifunctional space that does not follow the otherwise customary requirements for heating and ventilation.
