In the winter, the people who is moving between room and outdoor suffer from the cold stress because the thermal environments change significantly broad level. The researchers in the fields such as the building environment, the residential environment, the health care, the reports, the others has been performed the studies about the reducing of the cold stress as well as the establishment to the thermal comfort index in cold outdoor in the winter. For the extension of these studies, this work investigated the thermal responses of two subjects who was moving between room and outdoor in cold weather in winter evening. The subjects were one male and one female university student. This work investigated for the subject's Thermal Sensation Vote(TSV) and Mean Skin Temperature(MST) and the earlobe temperature, the physical thermal parameters at the indoor and the outdoor, it using by treadmill for setting of walking speed such as 4.3㎞ per hour, it focused three contents as follow; first, the time interval between the subject walking start in cold outdoor and the subject feeling cold sensation; second, the time interval between the subject returning in warm room and the subject feeling comfortable sensation; third, the subject's thermal responses with the physical thermal parameter such as Wind Chill Index(WCI). In conclusion, the time interval of first of above were 2~5 minutes(walking distance were approximately 140~360m), the time interval of second of above were 3~4 minutes. The result of this work will contribute to the research about the improvement of thermal comfort in the winter, the research fields of above.
