GREEN ROOFS HELP LOWER TEMPERATURES|綠屋頂.立體綠化 有效減緩熱島效應

This June and July, there have been records set in Taipei for high temperatures. As a subtropical to tropical island, cities in Taiwan all experience higher temperatures. So-called green roofs or 3D greening can reduce temperatures of the roof surface and the surrounding air. Both Taipei and Kaohsiung cities have new regulations for roofs to help lower temperatures. Rooftops provide a different view of the city. A view from the air shows corrugated iron roofs everywhere on rooftops. From infrared thermal imaging it can be seen that in the summer roof temperatures go up to fifty or sixty degrees. According to research, green roofs can lower temperatures by over 20 degrees. This can reduce indoor temperatures by 3-5 degrees. Surrounding temperatures will also fall. In recent years, many public buildings and schools have built green roofs, as a carbon reduction strategy. ==FU XU-XUN Yuanpei University Admin. Manager== It has huge benefits in term of the amount of air conditioning that we use, so we feel its really worth investing in ==HUANG YU-CHUNG Huxing Kongzhong Farm== Sweet potato leaves, ginger, leeks, these are nearly all ready nearly mature New Taipei City and Kaohsiung City were the first counties to promote green roofs. In 2011 New Taipei City required that new buildings of over 5,000 square meters, must create green roofs or set up solar panels. In 2011, Kaohsiung City Government also adopted autonomous regulations for new buildings over 50 meters to create green roofs over at least half the area. To encourage old buildings to create green roofs, it has provided up to NT$80 million in funding. ==HUANG ZHI-MING Kaohsiung City Govt. Public Works Bur. Chief Enginr.== Currently in Kaohsiung we have over 200,000 square meters and many hundreds of buildings that already have green roofs and our government buildings such as our Public Works Bureau, also has a green roof. In June this year, Taipei City caught up with New Taipei and Kaohsiung and required new buildings to green their roofs. ==KAO CHEN-YUAN Commissioner, Taipei City Govt. Dept of Economic Devlpmnt.== New buildings must have over 50 percent of their area planted with vegetation for a green roof as a norm in their technical specifications. As the climate becomes more extreme, the city will face waves of heat, wave and rain. Buildings that are energy wasters and polluters can be transformed starting from their roofs. This is not only relaxing and beautiful for inhabitants, it is also a necessary strategy for urban survival. Local government has taken a positive step. Next, it is up to central government to put forward a more proactive strategy to bring cities relief from the heat. TRANSLATED BY：CLARE LEAR 早上八點不到，城市裡的農夫紛紛出動、爬上屋頂，經營自己的秘密菜園。 ==湖興空中農場場長 黃谷忠== 地瓜葉 這個是薑黃 韭菜 有一些韭菜之類的 這是已快要成熟的玉蜀黍 屋頂是城市的另一張臉，從空中俯瞰，台灣都會區的屋頂幾乎都被鐵皮覆蓋。從紅外線熱影像儀可以發現，夏季屋頂溫度高達五、六十度以上。根據研究，屋頂綠化可以降溫達20度以上，頂層室內溫度可以降低3到5度，周邊溫度也會跟著下降，近幾年許多公有建築與學校陸續建置綠屋頂，作為節能減碳的策略。 ==元培大學總務長 傅祖勳== 對我們空調的使用來講 有非常大的利益 所以我們覺得 這是一個很值得投資的事情 新北市跟高雄市是最早開始推動綠屋頂的縣市。2011年新北市規定新建案超過5000平方公尺，就必須做屋頂綠化或設置太陽光電，高雄市政府2011年也通過綠建築自治條例，50公尺以上的新建築，綠屋頂面積必須達到二分之一以上，同時為了鼓勵舊有建築改成綠屋頂，還提供最高80萬元的補助經費。 ==高雄市政府工務局總工程司 黃志明== 我們現在高雄市約略有 超過20萬平方公尺的綠屋頂 已經成形了 已經好幾百棟的房子 都是綠屋頂 包括我們自己公有建築物 我們工務局逐年做一棟 相較於新北市與高雄市，台北市則是在今年六月，對新建築物的屋頂綠化做出規範。 ==台北市政府產發局主秘 高振源== 新建築要50%以上的面積 要來種植這些綠化 有規範在它們的 建築技術規範這邊 在極端氣候下，城市將面臨一波波熱浪的襲擊、暴雨的考驗。從屋頂開始改造耗能又不健康的建築，不僅是為了悠閒美觀，更是城市求生必需有的策略。地方政府已經著手進行，下一步就看中央政府能否，提出更積極的策略，讓城市一步步從熱島中解脫。 記者 張岱屏 陳忠峰 報導
