The indoor thermal environment of study spaces in university has a significant influence on occupants'learning efficiency and building energy efficiency.Through on-site measurements and questionnaire surveys,we measured the environmental parameters of open learning spaces,such as libraries,and closed learning spaces,such as teaching buildings,in universities in cold regions.It analyzed occupants'dressing habits,thermal preferences,and subjective evaluations of indoor temperature,humidity,and wind environment.The results showed that different occupants demonstrated varying sensitivity to thermal environments,and there were variations in dressing habits and thermal preferences.The majority of occupants were relatively consistent in their perceptions of room temperature and humidity across the different learning spaces,with a predominance of moderate perceptions.Except for those who felt moderate,occupants of open learning spaces tended to perceive the room temperature as slightly hot,while occupants of enclosed learning spaces tended to perceive the room temperature as slightly cold.Compared to closed learning spaces,occupants perceived open learning spaces to be drier.Occupants of both open and enclosed learning spaces generally had a lower expectation of wind speed,with more people expecting no wind.These findings offer valuable insights for optimizing the thennal environment of university learning spaces.
