Air Well System Of The Burgtheater Vienna: Sustainable Cooling Strategies

The Burgtheater Vienna was built at the end of the 19th century and it is one of the most important straight theatres in Europe It is equipped with an air well system for the fresh air supply and conditioning of the auditorium. The air is drawn in at the Volksgarten nearby and led to the auditorium via an underground tunnel. Warm and used air is dissipated through the ceiling and the roof of the theatre, The original dimensions of the facilities are still apparent.In the framework of this study, temperature, humidity and air velocity sensors were positioned at significant places along the ventilation system and the data was evaluated over the summer 2019. As a result, optimization potentials regarding operation control and air cooling using water atomization were evaluated. Finally, it was shown that the air well system can be used to sustainably condition the theatre in a time of rising temperatures.
