    Abstract: 都市綠化是一個對於淨化空氣與降低都市溫度非常有效的方法。綠屋頂、都市公園及綠園道其透過遮蔭、隔離、蒸發散作用及本身的熱容量，以致於擁有很高改善熱環境的潛力，進而降低建築空調系統的能源需求。為了釐清都市綠化的熱效應，此研究將透過數個固定測站收集到綠屋頂、都市公園及綠園道的溫度、濕度資料。在這個兩年期的計畫中，將透過溫度與綠化程度之關係的分析，計算出此三種都市綠化方式的冷效應。本研究之最終成果將成為未來政府推動以都市綠化改善都市高溫化與熱島效應問題之重要參考依據。本計畫之工作步驟如下： (1) 設置量測溫度、相對濕度之固定站與儀器於綠屋頂及都市公園； (2) 收集綠屋頂及都市公園之溫度與相對濕度資料； (3) 分析綠屋頂與都市公園減緩都市高溫化及熱島效應之效果； (4) 設置量測溫度、相對濕度之固定站與儀器於綠園道(第二年工作項目)； (5) 收集綠園道之溫度與相對濕度資料(第二年工作項目)； (6) 歸納綠屋頂、都市綠地及綠園道之整體冷效應(第二年工作項目)； (7) 提供政府未來推廣都市綠化之建議。
    Greening is a very efficient method which can not only provide fresh air but also decrease air temperature in urban area. Green roofs, parks and boulevards have the potential to improve the thermal environment in city through shading, insulation, evapotranspiration and thermal mass, thus reducing a building`s energy demand for space conditioning. For comprehending the thermal benefit of urban greening, the temperature and relative humidity data will be taken by several fix stations in some green roofs, urban parks and boulevards. In this two years project, the cooling effect of these three kinds of urban greenings will be calculated by the analysis of the relationship between temperature and greening level data. The results of this research will be the important reference for the government when promoting urban greening to improve urban warming and heat island effect in the future. The process of this project is as below: (1) Setting stations, instrument shelters and sensors for measuring temperature and humidity data in green roofs and urban parks. (2) Collecting temperature and relative humidity data of green roofs and urban parks. (3) Analyzing the thermal benefit of green roofs and urban parks for mitigating urban warming and reducing urban heat island effect. (4) Setting stations, instrument shelters and sensors for measuring temperature and humidity data in boulevards. (second year) (5) Analyzing the thermal benefit of boulevards for mitigating urban warming and reducing urban heat island effect. (second year) (6) Summarizing the total cooling effect of green roof, urban park and boulevard. (second year) (7) Providing the suggestions for promoting urban greening for government.
