Diurnal variations of indoor air humidity in Norwegian houses
In this study indoor air humidity and temperature levels have been measured in 87 houses in Trondheim, Norway. The temperature and relative humidity were measured at 15 minutes interval over a period of one week. The measurements were made in bedrooms, living rooms, bathrooms and outdoors. The moisture supply, which is the difference between indoor and outdoor air water vapour content, was calculated. The dataset has previously been analysed in regard to average values of moisture supply and its dependency of outdoor climate. The subject of this study however, were to analyze the daily variations of indoor relative hu-midity, temperature and moisture supply for the various types of rooms. The typical diurnal amplitudes of relative humidity, temperature and moisture supply are presented together with the statistical variation. The effect of influencing factors such as type of basic ventilation of the house, type of building, time of the year and the level of average indoor air humidity were investigated.
