经过调研得到长江中下游地区（以南京为例）梅雨季节住宅建筑室内热湿状况，并分析3种不同建筑能耗计算模型（整体建筑热湿空气流动耦合模型 HAM ，传递函数模型CTF ，有效湿渗透深度模型EMPD）的准确性。数值模型基于Matlab‐Simulink编写，使用调研数据进行验证，进而使用梅雨季节典型气象参数模拟分析。调研结果显示在2013年梅雨季节，多数时间内建筑室内温度高于28℃，相对湿度高于70％。数值模拟结果显示3种能耗模型对室内温度模拟的差异较小，而对室内湿度的模拟存在较大差异，特别是CTF模型误差最大。结果显示在长江中下游地区梅雨季节，当房间换气次数小于2 ACH时，围护结构对于室内环境湿缓冲的作用明显，选择合适的吸放湿材料可有效降低建筑能耗30％以上。

T he indoor thermal conditions of residential buildings during the plum rain season in East China (Nanjing for example) were obtained and the accuracy of three different building energy consumption models (whole building heat ,air and moisture model HAM ,conduction transfer function model CTF , effective moisture penetration depth model EMPD) were analyzed .The numerical model was implemented into Matlab‐Simulink and was validated using measured data from a field survey .Then the validated model was used for simulation analysis using typical weather data of plum rain season .The results from the survey showing the indoor temperature was higher than 28℃ and the indoor relative humidity was higher than 70% in most time of the plum rain season of 2013. Simulation results showed that there was not much difference when using the three models for thermal simulations ,however ,using CTF model for moisture simulation would result in large inaccuracy .During the plum rain season in Southeast China ,when the room ventilation rate is less than 2 ACH ,the moisture buffering effect of building envelope is obvious and the choice of proper hygroscopic materials can save up to 30% of building energy consumption .
