Investigation into use of self-study classrooms and impacts of their use strategies on energy consumption of teaching building in a Guangzhou university

 Investigates the occupants and full-house ratios of self-study classrooms in a teaching building of a university in Guangzhou and measures the indoor temperature and humidity in cooling season. Analyses the building energy consumption of the university teaching building with the existing use strategy of self-study classrooms. Proposes the new use strategies of self-study classrooms based on the self-study habits survey results of the university students and analyses the impacts of use strategies on building energy consumption of the university teaching building. The investigation results show that the occupants of self-study classrooms are insufficient with low full-house ratios. The air conditioning energy consumption accounts for 62.88% of total building energy consumption of the university teaching building, with higher indoor temperature and humidity than the allowable values. The impacts of use strategies on energy consumption of the university teaching building are significant. Compared with the existing use strategy, the energy saving ratio of the three new strategies are 36.49%, 32.07% and 27.95%, respectively.
