The influence of internal heat sources on the air flow rate and ventilation heat losses in multi-storey flats. Der Einfluss von inneren Warmequellen auf den Luftdurchsatz und den Luftungswarm ebedarf mehregeschossiger Wohnbauten.

Describes how internal heat sources such as bathrooms and kitchens can significantly influence stack effect in high rise residential buildings. Taking into account storage characteristics of surrounding walls derives relationship for determining behaviour of air temperature in internal kitchen. Discusses differences found by this method and computer method between values for ventilation heat losses according to TGL 112-0319.
