Exhaust air or exhaust gas shaft. Natural ventilation of dwellings under various conditions - a study of the parameters. Mit Abluft- oder Abgasschachten ausstatten. Naturliche Beluftung von Wohnungen unterschiedlicher Ausgestaltung - Parameterstudie.

A mathematical model was used to describe the natural ventilation of a modern residential building for various building construction and meteorological data. The calculations showed that exhaust air shafts have a very positive influence and that separate consideration of wind and stack effect on thenatural ventilation of buildings leads to a wrong interpretation. Both major influences must be considered together.
