To understand the indoor thermal environment and thermal comfort in naturally ventilated buildings in transitional season,taking student dormitory in Hainan as an example,a field study and questionnaire survey are conducted in student dormitory in Haikou to study its indoor thermal environment and thermal comfort. Calculation and analysis of thermal sensation,thermal comfort and humidity sensation by using statistical and building thermal environment analysis model. The results show that the measured and predicted thermal neutral temperature are 24. 7 ℃ and 25. 4 ℃,the preferred temperature is 26. 2 ℃,the thermal neutral humidity is 64%. The acceptable temperature range of 80% subjects is 19. 5 ~ 27. 9 ℃,respectively,which exceed the limits of the ASHRAE Standard 55—2010 comfort zone; The comparison with the thermal comfort research result in summer and winter of this region demonstrates that without changing indoor environment artificially,the adaptability and subjective expectation of human to the environment changes dynamically with the environment.
