Luminous Environment Measurement and Simulation Analysis of a University Library

The self-study area is a typical and mostly-used space in the library, therefore the light environment in this room directly affects students’ learning efficiency and physical health. Field measurements and questionnaire surveys were conducted on the light environment. The results showed that the average illuminance of the artificial light environment could not meet the standard, while the average illuminance of the natural daylighting and mixed light environment far exceeded the standard, but the uniformity was poor. Aiming at the above problems, ECOTECT and DIALux were, respectively, used to study the effect of different shading forms and indoor light environment under different shading and lighting schemes. The results confirmed that among the three shading methods of the horizontal device, vertical device, and sun-shading blind, the effect of sun-shading blind shading is the best, and the environmental quality is optimal with the uniform arrangement of LED lamps. In addition, control recommendations combining natural daylighting with artificial lighting are proposed.
