为了探索不同材料及构造外墙的热湿表现,设计了包括基准墙体在内的7种竹木结构外墙,分别以上海及北京典型气象年气象数据为边界条件,采用WUFI Plus进行全建筑热湿模拟.通过模拟,从居住舒适性、冷凝、霉菌生长、能耗等方面进行比较分析.模拟结果显示,综合来看W4号墙体有着较好的热湿表现;两种气候条件下较短时间段内需关注冷凝现象的发生;上海气候条件下发生霉菌的隐患低,北京气候条件下不存在霉菌隐患.验证了将竹质材料应用于墙体设计的可行性,同时也为新型墙体设计提供了思路.
Hygrothermal Simulation on Exterior Wall of Bamboo and Wood Structure
In order to reveal hygrothermal performance of exterior walls with different materials and structures,7 walls of bamboo and wood structure have been designed and simulations have been performed respectively under climatic condition of typical meteorological year of Shanghai and Beijing by WUFI Plus.Wall 1 to wall 7 were compared in regarding to living comfort,condensation,mold growth and energy consumption.The simulation results show that W4 performs well with regard to living comfort.Condensation phenomenon just should be paid attention to in shorter period in the two kinds of climate conditions.Low risk by mold would exist in the condition of Shanghai and no threat for Beijing.The feasibility of application of bamboo based material in walls has been verified.It also provides a new idea for the design of walls.
