溫室效應問題日益嚴重，強調「永續發展」的綠建築受到全球重視。根據台電資料顯示，照明用電在住/商兩部門占整體耗能約20~40%左右，若能利用取之不盡用之不竭的天然晝光源，並以蓬勃發展的微結構成型技術製作微菱鏡晝光導光板，結合現有氣窗系統，藉由晝光導光板將晝光導入室內提昇室內照明，將能節省 25~50%的照明用電，達到節能目的。
本研究目的為首度使用無機-有機混成材料，利用微結構轉印製作微菱鏡晝光導光板，將製作出來的微菱鏡晝光導光板結合現有氣窗系統，達到建築節能目的，期對全球改善溫室效應有所幫助。

The greenhouse effect has become serious concerns recently. The energy consumption of artificial light takes about 30~40% of total energy consumption of a building. The use of suitable structure of sunlight guiding can save 25~50% energy consumption of the artificial light. The inorganic-organic material combines the positive property of inorganic (weatherability) and organic (flexibility), and with high transmittance at visible region is suitable for fabricating optical element with microstructure. In this study, the microstructure on master mold is machined first and transferred to PDMS, followed by imprint on inorganic-organic material. Finally, the sunlight guide of inorganic-organic material is produced and assembled to window modules of buildings for guiding sunlight from outdoor to light up indoor.
