Detailed equations of combined heat and moisture transfer have been proposed to analyze temperature and humidity fluctuation of walls. They are, however, too complicated to apply to transient room temperature and heat load calculation of multiple zone buildings. Therefore moisture capacity of the room is generally added to the room air to take account of moisture adsorption and desorption (sorption) of walls and furniture. In this paper, we propose a simplified calculation method for sorption on walls. The final purpose of this method is to be combined in transient room temperature and heat load calculation instead of the moisture capacity of the room. The proposed simplified method uses an idea of moisture capacity layer on wall surface. The accuracy of the proposed simplified method is verified in comparison with the detailed method using combined heat and moisture transfer by water potential of walls.
