垂直導光通風管於室內導光性能之研究
A study of the lighting performance for the lighting-Ventilation Stack
摘要
台灣位於日照量充足之亞熱帶氣候區，對於自然光利用的效益相對於高緯度國家更具優勢，故若能增加自然採光於建築物室內環境之應用，不僅能提昇室內光環境品質並創造舒適的室內環境，亦可降低建築用電量，以符合節能之精神。 本研究將以熱濕氣候區建築為例，針對建築屋頂層結合導光通風塔之採光性能為研究主軸，透過戶外足尺模型建置及足尺模型變因實驗，進而分析探討實驗數據，以歸納出有安裝導光管裝置之採光性能優於無安裝導光管裝置，另外，全晝光照度與導光效率成正比關係，但和均齊度成反比關係之結論。 冀望本研究所提出之性能結果，可作為後續研究者於足尺實驗之參考或建築實務界於設計階段中，針對特殊空間需求（如高照度值或高均齊度）之設計參考依據。

Taiwan, located in subtropical area, has a good potential to efficiently utilize the abundant natural sunlight for its geographical feature. Therefore, increasing daylighting in buildings by employing designs such as natural lighting and ventilation not only improves the quality of indoor light to create comfortable indoor environment, but also decreases energy consumption. The objective of this research is to study the effects of design factors on lighting performance in buildings in Taiwan. In this study, we established full-scale model to investigate the lighting performance of lighting-ventilation stacks employed in buildings localized in subtropical areas. We demonstrate here that buildings with lightpipe have better indoor lighting than buildings without lightpipe. In addition, illumination of daylight is in direct proportion to average of indoor illumination and lighting efficiency, but in inverse proportion to the uniformity of illumination. This study provides information to improve indoor lighting in buildings with higher illumination and uniformity of illumination.
