    摘要: 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。在這個一年期的計畫中，將透過溫度與綠化程度之關係的分析，計算出此二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。
    Greening is a very efficient method which can not only provide fresh air but also decrease air temperature in urban area. Green roofs and parks 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 and urban parks . In this 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.
