The Effect of Previous Exposure Temperature on People's Perception in Semi-Outdoor Spaces

Past thermal experience is related to the memory and seems to be responsible for the changes in people’s expectations. In order to investigate how the previously air conditioned exposure impacts thermal perception in semi-outdoor spaces, the controlled experiments were conducted, with a total of 36 undergraduates who participated as the subjects. Based on the controlled experiments, the impact of previous exposure temperature to air conditioning was examined. It was found that the previously air conditioned exposure temperature has impact on thermal perception in semi-outdoor spaces. Based on the experiments, it can be found that the impact of the air conditioned exposure temperature is not significant when the temperature difference between the air conditioned environments is about 2°C or 3°C. However, the impact of the air conditioned exposure temperature appears significant when the temperature difference between the air conditioned environments is up to 5°C.
