The operating hours of class rooms in university buildings vary according to each class schedule, and the operating schedule of air conditioners is flexible. It has a high occupancy density compared to the short occupancy time, so the optimum IEQ (Indoor Environmental Quality) cannot be guaranteed. In addition, the learner also shows the limit of the opportunity for thermal adaptation. Therefore, in this study, quantitative evaluation was carried out by calculating the comfort temperature by analyzing the metabolic rate before class, thermal comfort related to thermal adaptation for a short time after class, and changes in the occupant’s thermal sensation during lecture. As a result of examining the occupants’ thermal sensation (Thermal Sensation Vote, Comfort Sensation Vote, Thermal Preference), it was found that they showed thermal stability after class. It could be understood that this was influenced by the difference in the metabolic rate of the occupants that occurred within a short time before class.
Through the difference in comfort temperature of 1.78°C, thermal comfort before and after class was quantitatively evaluated. In order to promote the air conditioning operation strategy of the university building lecture room and the comfort of the indoor heating environment, it is necessary to identify and reflect changes in short-term thermal adaptation, metabolic rate, and thermal comfort of occupants. |
