English abstract:
The aim of the work is to clarify how the façade system and the cooling ceiling impacts the air movement within a room. Therefore tracer gas measurements with different inject locations and different room set-ups were done. One part of the results show the impact of different façade systems - a single skin façade and a single
storey double skin façade - on the air movement. The measurements show an increase of concentration within the ceiling zone which is attributed to a higher air flow rate over the ceiling.
Furthermore different set ups of the cooling ceilings were measured - one with natural ventilation over the suspended cooling ceiling and one without natural ventilation. The measurement results
show that there is a decrease of concentration due to missing natural ventilation. The measurement results show a clear difference in the rate of concentration on different room points due to solar radiation, the location of impact and the room set up.
