臺北科技大學位於台北市中心區,屬典型都會校園。隨時代轉變,學生人口逐漸增加,為舒緩對校舍使用量與考量學生安全,校方開始興建大型校舍以供使用,因此既有綠地大量減少,既有水文狀態改變,失去調節都市微氣候之能力,對環境產生相當大之影響,與都市之關係也轉為封閉且不友善。為改變校區開發所造成之環境影響及恢復與都市有善關係,於2003年受教育部「永續校園推廣計畫」補助,以「生態環境恢復與維護」及「永續建築」兩大目標開始進行規劃,2004年已完成第一期工程,2010年完成第二期工程。從2004年至2010年止期間已完成透水鋪面、綠屋頂、植生滯留池、入滲溝、雨水回收、草帶等相關生態設施(LID/BMP設施)之施作。 本研究利用LID決策支援系統(SUSTAIN),模擬北科大既有LID/BMP設施,對於地表逕流之削減效益,模擬結果顯示,從2010年1月1日至2011年12月31日止,北科大既有LID/BMP對於兩年之地表逕流削減量達6751m^3,削減效益達2.0%,整體削減效益達13%,以透水鋪面組合最具成效,佔75%之削減量,其中各設施對於地表逕流削減量,植生滯留池為1.09m^3/m^2、透水鋪面為、1.11m^3/m^2、綠屋頂為0.76m^3/m^2、草帶為0.39m^3/m^2、入滲溝為0.40m^3/m^2。
Taipei University of Technology is a typical urban campus in the center of the Taipei city. As time change, student population increases, the school started to build school building in order to ease the use of the remaining building and secure student’s safety. Therefore, the reduction of greenbelt causes hydrology changes and the school lost its ability to adjust city microclimate. In order to repair the environmental impact and become eco-friendly, the school received the “Sustainable Campus Program” subsidy and started to map out based on “Restoration and Maintenance of the Ecological Environment” and “Sustainable Buildings”. The first issue of the construction has been done at 2004, and the second issue was done at 2010. Permeable Pavement, green roof、Bioretention、Infiltration Trench、Rain Barrel、Grass Strip, etc., LID/BMP facilities has been done during the construction. This study uses LID Decision Support System (SUSTAIN) to simulate the reduction of surface runoff benefits with LID/BMP facilities in NTUT. The results shows that the quantity of surface runoff reduced from those facilities in NTUT at 2010/01/01 ~ 2011/12/31 is 6751m^3, reduction benefits is 2 %, total reduction benefits is 13%;the best results is the permeable pavement, the percentage of the reduction volume is up to 75%;the others surface runoff reduction volumes such as bioretention is 1.09 m^3/m^2、permeable pavement is 1.11 m^3/m^2、green roof is 0.76 m^3/m^2、Grass Strip is 0.39 m^3/m^2、Infiltration Trench is 0.40 m^3/m^2。
