通过对重庆地区农村住宅冬季室内热环境的实测分析，表明农村住宅室内平均温度仅比室外温度高1～2℃，室内温度低于9℃的频率约占80%，农宅的总体热环境还比较差；农户的生活习惯也会影响到室内热环境的变化，特别是堂屋温度受到户门开关使用的影响比较突出明显，白天出现较大的波动和下降。为了研究这种影响的程度，采用Designbuilder软件建模；根据堂屋温度的实测数据确定户门的日常使用方式，模拟住宅室内温度。结果显示，农宅在室外低温条件下，室内温度都没有达到《农村居住建筑节能设计标准》所要求的低限取值8℃，所以围护结构需要加强保温；其次户门的日常使用方式导致堂屋温度白天出现较大的下降，最大降幅达到3.2℃，累积降温达到15℃，并对相邻房间温度产生不利影响。

Through thermal environment measurement and the analysis of rural residence in winter in Chongqing, it is showed that the average temperature of rural indoor residence is higher than the outdoor temperature by only 1~2℃, and the frequency of indoor temperature lower than 9℃ accounts for about 80 percent. The overall thermal environment of rural residences is relatively poor, and farmers’ living habits also influence the indoor thermal environment, especially the door using mode. It is observed that the living room temperature experiences larger fluctuation and declines in the daytime when the door use is more often. In order to study this effect, we adopt Designbuilder to build the model, and determine the daily door use by the measured room temperature to simulate the indoor temperature. The results show that the indoor temperature fails to reach 8℃, which is the low limit required by the Rural Residential Building Energy Efficiency Design Standard in low outdoor temperature conditions. Therefore, firstly, the rural residences need strengthen their function of thermal insulation; secondly, the living room temperature declines sharply due to the usage of the door in the daytime with a maximum temperature decline of 3.2℃ and a cumulative decline of 15℃, which generates an adverse effect on the adjacent room temperature.
