In order to improve the deficiency of existing daylighting climate zones and investigate the characteristics of the typical daylighting climate zones
the ratio between direct light
diffuse light
global illumiance and extraterrestrial horizontal illumiance were taken as parameters. On the basis of annual observation data of twelve typical light climates zone
daylighting climate of various regions was investigated by PGD diagram. This method could more intuitively and accurately reflect the characteristics of regions and be easier for comparing the difference between light parameters .Through analysis
the daylight distribution profile of twelve zones were obtained
with which it could be reference for daylighting design.
