摘要

本研究為了探討普通教室走廊與該牆面之設計，對於室內採光效能之影響；首先採用田野調查法，調查台中地區八所大學具單邊走廊設計之普通教室，探討其走廊牆面開窗型式、開口率、玻璃材質、走廊寬度…等；並以等距測量其走廊及室內照度，計算出晝光率與均齊度。並將所獲得資料整理出走廊與該牆面影響室內光效能之因子，分析出四種具代表性教室空間樣本。根據以上的結果，製作為1/10的縮尺模型，利用「全天空圓頂（Sky Dome）」模擬在漫射光環境下，四種不同開口率、四種不同走廊寬度及三種不同玻璃材質，對室內晝光率與均齊度之影響，實驗獲得的資料採用SPSS統計分析軟體進行分析。
田野調查獲得如下結果：1.牆面開口型式為全開且清玻璃材質者具有較佳晝光率；2.牆面為上部開口且清玻璃材質具較佳均齊度。天空圓頂實驗成果獲悉：1.開口率越大室內採光效能越佳，具有較佳的晝光率與均齊度；2.走廊寬度增加，影響室內採光效能，晝光率降低但均齊度較平均；3.開口部牆面為上方清玻璃下方霧玻璃材質者具有較佳的晝光率與均齊度。
本研究對走廊與牆面之設計綜合建議如下：1.開口率70%、走廊寬度180cm、上方清玻璃下方霧玻璃材質者具有較佳的採光效能；2.並以開口率50%~70%、走廊寬度180~240cm、清玻璃或上方清玻璃下方霧玻璃材質為建議的參考範圍；3.走廊寬度的增加造成室內晝光率降低，不符合標準值，建議可以增加導光板或走廊的反射率，以增加室內照度。

The main purpose of the study is to investigate the effect of the design of the corridor and the wall on the classroom indoor daylight performance. 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.
