In this paper, the influence of moisture soiption and dcsorption of walls on space conditioning load is exaluated by dynamic simulation based on detailed building physics taking account of heat and moisture transfer and aiifloo of whole huildings. Then sensitive analysis is performed with a number of factors, such as preset temperature and humidity of space condiliomng, ventilation amount, property of inferior materials and so on, which influence indoor humidity. Eleven factors that affect indoor humidity are detined with the extent of the influence by the multiple regression analysis on the basis offhe sensitive analysis. It is clarified that the moisture sorption and desorpf ion of walls are influence both heating and cooling load at a rate over 10 percent and water vapoui pcirncance and moisture capacity of interior finish are the significant factor on the moisture solption and desorption.
