Opera House, Baden-Baden

Assignment

A new ventilation concept was planned for the Festival Opera House in Baden-Baden. Four air nozzles introduce chilled air above the parquet floor producing a large vortex circulating above the visitors. The load plane from the audience room was intended to ascend into the eye of the vortex. In cooperation with the Association of Engineers Simon, the realisation of this concept was investigated and data to predict the thermal comfort established.

Solution
A 1:10 scale festival opera house with air outlets and the four nozzles was constructed observing model principles. A potential theoretical flow simulation in combination with the air flow investigation ensured an optimisation of the nozzle angle and their aerodynamic properties. The ventilation turned out to be steady under both conditions with full load and critical partial loads. Thermal comfort could therefore be guaranteed not only in the auditioria, but also in  the orchestra pit and on stage, which finally lead to an implementation of this ventilation concept.

Advantage
Realisation of a cost-effective and stable ventilation system for large conference or meeting rooms.
