When it opened in the seventies, the Scharoun theatre in Wolfsburg, Germany, made it possible for the quality of plays, ballet and musical theatre alike to take a huge leap forward and has remained a great attraction to this day. After forty years, it was time for modernisation: not just in terms of stage technology, the furniture, flooring and typical colours all needed gently bringing up to date.
What's more, new requirements for safety and fire protection technology meant that further modifications were also necessary. Architects were asked to work locally in close cooperation with all building and monument preservation societies to find an ideal solution that managed to combine aesthetics and design under complex conditions. The theatre was re-opened in January 2016.
In the theatre hall, supply air is supplied via air outlets at top of doubled chairbacks. A full-surface floor plenum underneath feeds the supply air into the floor brackets of the chairs. Special air guide elements have also been integrated into the chairbacks to increase comfort properties and ensure a draught-free air flow path. The optimum arrangement of the air guide elements was determined during a flow trial at the Kiefer flow laboratory using the original theatre chairs and compliance with the required values for room acoustics and the absence of draughts was confirmed. By reproducing the existing perforated plate on the top of the theatre chair 1:1, we have been able to meet all building and monument preservation requirements that stipulate an invisible ventilation solution without limitation.

In the case of conventional displacement air systems, the supply air is fed to the room gently with little turbulence. Displacement air systems are characterised by low air velocities and low temperature differences between the supply air and ambient air in the occupied zone. Owing to the combination with the inductive air guide elements developed by Kiefer, INDUQUELL is, on the contrary, capable of high temperature differences of up to – 8K with greater comfort.
