The stu-dy first adopted a field research, examining classrooms with unilateral corridor in eight universities in Taichung, further discussing their sizes of openings, aperture ratios, glass materials, and width of the corridor. The study then measured the corridor and indoor illumination from same distance, obtaining the daylight factor and uniformity. With the collected data, the study sorted several factors that affect indoor illumination, resulting in four representative classroom samples. Based on the data collected, a 10: 1 scale model was also adopted in this research for analyzing how four different aperture ratios, corridor widths, and three different glass materials would counteract with indoor daylight factor and uniformity in a Sky Dome under diffuse light. SPSS is used for data analysis. The result from the field research includes: 1. Walls with full size of opening and transparent glass materials have better daylight factor; 2. Walls with upper opening and clear glass materials have better uniformity. Through the Sky Dome experiment, the results suggest: 1. The larger the size of opening, the better the indoor illumination and the better daylight factor and uniformity; 2. The increase in the width of the corridor affects the indoor illumination, with decrease in daylight factor but with much equal uniformity; 3. The wall with upper transparent glass and lower translucent glass results in better daylight factor and uniformity. The results of the study suggest that: 1. the indoor illumination are betterwhen the opening rate is 70%, corridor is 180cm in width and the transparent glass material and translucent glass material are used in the top and the bottom of the window respectively; 2. opening rates ranging between 50%~70%, and corridor width ranging between 180~240cm, with transparent glass windows or with transparent glass in the top and translucent glass at the bottom are served as a reference range; 3. The indoor daylight factor decreases as the width of corridor increases which does not conform to the standard value. In such condition, increase in light guide plate and corridor reflectivity are strongly suggested to increase the indoor illumination.
