Kitchen ventilation.

Field experiences of airborne moisture transfer in residential buildings.

This paper deals with field experience of airborne moisture transfer problems in houses. Two types of phenomena are discussed in more detail; the infiltration of moist air from crawl spaces and the propagation of moist air produced in kitchens. A modified depressurisation test is described to determine the air tightness of ground floors. A case study is briefly discussed where different remedial measures have been tested to evaluate the moisture removal effectiveness in kitchens.

Inhabitants' behaviour with respect to ventilation.

During winter periods in four types of newly built terraced dwellings and in apartments of a flatbuilding,the daily behaviour and motivations of the inhabitants with respect to airing and ventilation have been studied. In total the information was obtained from 279 households. A combination of verbal interviews, diaries and technical measurements are used as methods of investigation. On basis of the findings,calculations can be made about air flows in occupied dwellings.
