R. Bacher, MSC Contractor: Wieselthaler Ges.m.b.H The building Project: Traungasse · Vienna, Austria The building with offices and shops is situated in a premium location at the edge of the downtown area of Vienna with an excellent infrastructure. Several shops and offices are located on nine floors. The ventilation concept The individual ventilation of the regular stories are handled using decentralised ventilation units Type FSL-B-ZAB, which was integrated into the parapet of the façade. In addition to the mechanical ventilation with heat recovery and air filtration, this device concept guarantees the heating and cooling of the offices. The devices convince customers due to their low noise power, stable outdoor air supply independent of the weather and wind situation, and optimum discharge of supply air. Façade axes that are not equipped with one of the above mentioned decentralised ventilation units can be supplemented by a secondary air ventilation unit Type FSL-B-SEK. This creates a possibility for dissipating higher thermal loads.

Project information Traungasse office building Decentralised sill ventilation units FSL-B-ZAB · FSL-B-SEK Function description for the supply and extract air unit (FSL-B-ZAB) Supply and extract air units maintain a high air quality in rooms by supplying prepared outdoor air to the room and extracting “used” room air. For air discharge, the unit has two radial fans. The supply air fan takes in outdoor air, which flows through a volume flow limiter, a non-return damper, a shut-off damper, and a fine dust filter. These components prevent the exceeding of the dimensioned outdoor air flow rate through...
