摘要：

In order to compute the natural illuminance, it is necessary to select one correctly among the 15 sky types defined by CIE to correspond to real sky. Firstly, according to the ratio of the sky illuminance on a vertical surface facing the sun to the sky illuminace on a vertical surface back the sun, the 15 sky types can be divided into 6 groups. Secondly, the 6 groups sky types can be further divided according to the ratio of the window sky light illuminance formed by the result on the two different measuring points in the space model. And ultimately, the correct type can be chosen from the 15 sky types of CIE standard general sky model. The result from the comparison between the selected sky type and the real sky type shows that this method works accurately on choosing the correct sky type for the real sky. ï¿½, 2015, Chines Academy of Sciences.
