In order to explore the influence of building parameters and occupants' behavior patterns on building envelope condensation in Wuhan rural residences during plumrain season,based on experimental verification,considering the factors,such as window-wall ratio, external wall reflectivity,window opening mode and external wall insulation layer,the designer's simulation tool kit(DeST)was adopted to simulate the indoor thermal and humid environment of rural residences in Wuhan.The building envelope condensation in rural residences was analyzed during plumrain season by using condensation rate.There search results show thatruralresidencesin Wuhan should not blindly pursue natural lighting,and the window-wall ratio should be 0.6.Keeping window closed when temperature rises sharply can effectively alleviate the condensation problem.From the view of anti-condensation,it is not suitable to add external wall insulation layer inrural residences in Wuhan.
