Abstract

In three different occupied houses water boilers were set up to release approximately 1 kg of steam during approximately 0.5 hours. Before, during and 40 hours after this incident moisture content in indoor air and outdoor air was measured as well as temperatures, air change rate, air volume in the house and areas of main inner surface structures. The ability of the houses to absorb water in their structures after these experimentally created humidifying incidents was assessed based on mathematical models. Moisture absorption was most significant in the old masonry house during the first four hours after the steam was added. After this period the modern masonry house, with the slowly reacting concrete, had the highest absorption. At all times the least absorption was seen in the wooden house.
