The main purpose of this paper is to validate the prediction equation for interior daylight illuminance to the office buildings by field measurement. The prediction equation for interior daylight illuminance was validated to the office with all-glass. However, the performance of the daylight illuminance is affected by the window size and characteristics. In this study, the measurements of indoor illuminance were carried out at the different office in summer. The effect of the window size, roll blinds and interior materials on interior daylight illuminance was analyzed. The results show that the influences of the blind and indoor surface reflectance to the interior daylight illuminance aer high in small sized office.
