Abstract
This research aims at developing a moisture expulsion exterior wall which can discharge indoor moisture to the outdoor air by the use of a humidity control material. The indoor moisture is naturally discharged using the difference in water vapor pressure between the indoor and the outdoor air in winter. In the present study, the humidity reduction effect under winter climate conditions was investigated using a field test house located in Hakusan City. And the effect of the moisture expulsion exterior wall structure was shown as a moisture expulsion quantity through one winter season.
