N2 - People's subjective response to outdoor thermal environment cannot be directly interpreted by environmental influence factors (temperature, humidity, radiation and wind, etc.), thus thermal comfort indexes (PET, UTCI, SET∗, PMV) were needed to evaluate impact of outdoor thermal environment on human beings. Due to the influence of people's adaptation, the reactions to environment varied by climate and locations, and many related researches have been carried out by researchers all of the world. This work aimed at studying on the colleague students' subjective response to outdoor thermal environment in winter in severely cold climate city. Questionnaire survey was carried out in university campus in Harbin, which is a typical severely cold climate city in China, and 553 effective questionnaires were collected totally. By choosing Physiological Equivalent Temperature (PET) as thermal comfort index, the relationship between thermal sensation vote (TSV) and Physiological Equivalent Temperature (PET) was analyzed. The result of this study was compared with a former study (more than 2000 samples) carried out in winter in Harbin before, and it was shown that, when PET equals to -8.7?, both of young colleague students (age rages from 18 to 24 years old) and the large scale samples (a wide covered age range) felt cool (TSV equals to -1.8). When PET was over -8.7?, the colleague students felt cooler while when PET was lower than -8.7?, they felt warmer, revealing that the young colleague students' thermal sensation was not sensitive as the result of large scale samples, conducting that the research of outdoor thermal comfort in winter in severely cold climate cities may also take people's age into consideration as influence factors.
