Weißenhorn CAE – H. König The building The Laimer Würfel building on the city centre site in Landsberger Strasse in the Laim district of Munich, Germany is a contemporary office building characterised by the highly efficient use of surfaces and great individuality. Each of the 11 upper floors in the complex has approximately 1,900 m2 of office space. The multi-functional ground floor includes retail areas, a conference area and a casino. Two impressive entrance areas lead into the Laimer Würfel building. Supply and extract air unit, type FSL-B-ZAB left-handed construction The striking element of the facade – copper – is contrasted and complemented by preweathered zinc elements. The multi-facetted appearance of the facade is finished off by high quality solar control glass on the ground floor and expanded metal solar shading in front of the office windows. The upper storeys are individually and mechanically ventilated by type FSL-B-ZAB decentralised ventilation units built into the sill of the facade. The use of these modular units with interchangeable function boxes is the best way to accommodate the flexibility of office use. This design of unit provides heating and cooling of the office spaces, in addition to mechanical ventilation with heat recovery and air filtration. Some facade modules do not have these decentralised ventilation units but are equipped with recirculated air heating and cooling units of the same dimensions (type FSL-B-UML). The system is further complemented by opening windows and additional cooling capacity by means of chilled ceilings may also be provided to deal with higher thermal loads. The ground floor, kitchens and store rooms are ventilated by a central plant air conditioning system.

A TROX GROUP Company Project information – Laimer Würfel – Decentralised sill ventilation units FSL-B-ZAB PI/FSL/12/EN/2 Function of the supply air and extract air unit (FSL-B-ZAB) The outside air is taken in through the weather-resistant louvres. The mechanical automatic flow rate controller ቧ at the unit entry limits the outside air volume flow to a set maximum. This also prevents excessive external air flow which could occur due to high wind pressure on the facade thus causing draughts in the conditioned space. The backdraught damper prevents conditioned air being sucked out of the room against...
