A STUDY OF THE DAYLIGHT CLIMATE IN CHINA BASED ON THE TYPICAL YEARLY DAYLIGHT ILLUMINANCE

摘要

Natural light climate data is the precondition and foundation for daylight design, simulation and research. In this paper, typical yearly daylight illumiance data of 273 cities in China were obtained, by using Perez model and typical yearly meteorological data of DeST. Based on these data, we studied and analyzed the daylight climate of China, and provided basic data for dynamic daylight simulation and lighting energy analysis.
