Field study on winter indoor thermal comfort of stilted buildings of Miao nationality in Guizhou

 Investigates the indoor thermal environment parameters of 75 stilted buildings of the Miao nationality in Denglu village, Taijiang, Guizhou in winter. At the same time, conducts a questionnaire survey to 145 residents on thermal sensation, thermal comfort and other subjective feelings, and analyses the test and investigation data by the statistical regression method. The results show that the measured thermal neutral temperature in winter is 14.3 ℃, the predicted thermal neutral temperature is 18.5 ℃ and the difference between them is 4.2 ℃, the preferred temperature of residents is 16.5 ℃, and the accepted temperature scope for 80% is 6.5 to 21.2 ℃. The research results show that compared with those who live in the rural area of the Han nationality with similar latitude in hot summer and cold winter zone, the residents of the Miao nationality in Taijiang, Guizhou have lower measured thermal neutral temperature and floor level of accepted temperature scope for 80%. Analyses the cause of the phenomenon.
