Sky luminance distribution types in China

Abstract

According to Chinese daylighting climate data, combined with the standard of Commission Inernationale de l’Eclairgae (CIE) general sky luminance distribution (SLD), the sky luminance distribution of typical daylighting climate zones in China was studied. Through the research on reference SLD of overcast, intermediate and clear types, the standards of clear and overcast SLD are consistent with CIE general sky, and the intermediate SLD has greater error with CIE general sky. The main types of Chinese sky luminance in different daylighting climate zones were obtained, which provide the basic data for simulation and forecast of China natural light, and provide reference for using the standard amendments of China future natural light.
