Abstract

Abstract

Wind-driven rain is the main external factor causing rainwater infiltration in exterior walls，and there are significant differences in wind-driven rain climate conditions in various regions of China. This study proposes a method for assessing wind-driven rainwater infiltration climate risk that integrates building thermal design zoning，along with a set of corresponding indicators. The risk level of wind-driven rainwater infiltration in the main towns of existing building thermal design zoning was evaluated using these indicators，and a climate zone map for wind-driven rainwater infiltration risk in China was developed. The results show that the severe cold and cold regions are predominantly low-risk，accounting for 80. 2% and 95. 3%，respectively，with no highrisk towns observed in either region. In contrast，the hot summer and cold winter，hot summer and warm winter，and mild regions exhibit the highest proportions of medium-risk areas，at 68. 2%， 66. 7%，and 59. 1%，respectively. Among these，the hot summer and warm winter region is particularly significant，with a high-risk proportion reaching 25%. These findings emphasize that even if thermal design standards are consistent，differences in waterproofing design requirements for buildings in different regions should also be fully considered.
