Comparison of adaptive thermal comfort between typical rural and town residential houses in southeast Guizhou in winter

 In order to reveal the discrepancy of indoor thermal comfort between rural and town residential houses in winter, conducts a questionnaire survey among 178 town residents of 83 families and 145 rural residents of 75 families in southeastern area of Guizhou. At the same time, uses the adaptive coefficient λ proposed in the adaptive PMV model (aPMV model) to quantitatively calculate the adaptive levels of human body. The result shows that the measured thermal neutral temperature and 80% acceptable temperature limit of town residents in winter are higher than those of rural residents. The adaptive coefficient λ value of town and rural residents is -0.39 and -0.46, respectively. The adaptive level of rural residents is higher than that of town residents. The research suggests that the difference in thermal resistance of clothing is an important reason for the difference of thermal neutral temperature between town and rural residents. At the same time, behavioral adjustment and psychological adaption also have an impact on their thermal comfort.
