The purpose of this paper is to verify the accuracy of direct illuminance calculation based on window's subdivision. First we presented basic discretized equations for daylight factor calculation under assumption of uniform sky and CIE standard overcast sky. Next we applied these equations to the actual daylight factor calculation. Judging from comparison between theoretical results and results of discretization method, following 2 aspects were obtained. 1) Although the accuracy is affected by the fineness of subdivision or the way of configuration factor's calculation, the discretization method is as accurate as the theoretical method. 2) The discretization method is excellent to deal with incident angle characteristics of transmittance and the influence of occlusion in the complicated room.
