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.
