Background: Lighting is a basic need for human beings and affects their physical, physiological, and psychological behavior. The required level of lighting for visual performance must be provided in order to ensure health and wellbeing. Students spend much of their time studying in libraries, and thus, sufficient lighting is necessary in libraries. Therefore, the aim of the present study was to determine lighting intensity in university libraries in Rafsanjan, Iran.
Materials and Methods: The present cross-sectional study was conducted on 13 university libraries of Rafsanjan in April 2014. To assess natural and total lighting intensity, the network method was used. Lighting intensity was measured in a total of 314 stations in the university libraries of Rafsanjan. The collected data were analyzed using descriptive statistics.
Results: The men’s section of the library of Vali-E-Asr University of Rafsanjan had the highest total lighting intensity (1265.40 ± 530.95 lx) and the men's section of the library of the School of Medicine, Rafsanjan University of Medical Sciences, had the lowest total lighting intensity (91.06 ± 29.40 lx). Among the 13 study halls of the studied libraries, 4 (30.7%) halls had no windows. The lack of windows has an undesirable effect on the intensity of natural lighting.
Conclusions: Based on the results of this study, the average lighting intensity in 50% of the studied libraries was less than the Iranian standard. Therefore, the redesigning and modification of the lighting systems of these libraries are necessary.
