The Impact of Daylight Illuminance on Students’ Seat Preference in a University Library in Beijing

This paper aims to study college students’ feelings about the indoor daylight environment of the library. Taking a university library in Beijing as an example, a combination of questionnaire and illumination measurement was used to investigate students’ choice of library seats and the time period when they were satisfied with the daylight environment in different seasons. In addition, the daylight simulation on illuminance was also used during the study. It was found that students have specific expectations of the daylight environment and the daylight environment influences their seating preferences and comfort in different seasons. Throughout the year, students preferred seats with adequate sunlight. However, the degree of satisfaction decreased with a too high level of illuminance. The range of the illuminance that most students are satisfied with is 900–1050 lx.
