Natural ventilation of compact buildings in industrial-scale dairy farming. Freie Luftung von Kompaktbauten der industriemassigen Milchviehhaltung.

The dairy plants of type MVA 1930 are compact structures with a floor area of 92mx120m. Despite this size the dairy plants - with the exception of certain special areas - can be naturally ventilated over long periods of time. The pen climate parameters for a mechanically and a naturally ventilated plant of the above mentioned type are essentially similar. It seems, therefore, unfounded to restrict natural ventilation to buildings of a certain width. It is rather the formation of the envelope of the building which should be seen as the deciding criterion.
