臺灣既有建築實施垂直綠化評估基準與權重分配之研究

A Study on the Assessment Criteria and Weight Distribution of Vertical Greening Used on Existing Buildings in Taiwan

指導教授 : 彭光輝

摘要


近年來政府積極推廣綠美化,從公園、空地、屋頂至於建物立面等地方進行綠化作業,以提升都市的綠化量,不僅使視覺觀感綠視率的提升,亦能達到減碳降溫的效果,垂直綠化儼然成為建築的新顯學。 本研究藉由文獻回顧檢視垂直綠化技術發展及相關案例應用,並分析現行國內垂直綠化的獎勵制度,歸納垂直綠牆應用之相關影響因子,並透過模糊德爾菲法篩選出專家群體決策之評估因子,進而構成具檢定效果的既有建築實施垂直綠化評估體系,再運用層級分析法專家問卷提供之量化數值,統計分析臺灣既有建築實施垂直綠化評估基準之權重值及優先順序。 研究結果顯示,在第三層級之全體專家決策中,「施作成本」0.142為權重值最高之評估項目,「隔熱與節能」0.127為整體層級排序第二、「澆灌系統」0.100排序第三、「植栽維護方式」0.081排序第四、「調節微氣候」0.071為排序第五重要之評估因子。據此提供規劃設計者完成初步既有建築實施垂直綠化評估基準與權重分配其優先考量因素之參考,或於實施垂直綠化後之改善建議,以促進垂直綠化發展,降低評估決策風險,達到永續經營的理念。

並列摘要


The government has actively promoting landscape greening for parks, open spaces, roofs, even the building walls in recent years. With the growing greenery development, the green looking ratio and energy efficiency are also improving. Vertical greening has become architectural famous doctrine. Through case studies and literature review on vertical greening development, this paper analyzes the current incentive system and induces relevant factors of vertical greening applications. Besides, this study aims to construct the assessable evaluating system of vertical greening and effect on the existing buildings via Fuzzy Delphi Method (FDM). Using the weight value provided by the expert questionnaire survey through the Analytical Hierarchy Process, this paper tends to compile statistics and measure the relative weights and priority order from the assessment standard of vertical greening practice in the existing buildings in Taiwan. The conclusion of this study shows that, upon the third level of assessment criteria, the first factor is “Installation cost” (weight value is 0.142); the second factor is “Insulation and energy saving” (weight value is 0.127); the third factor is “Irrigation systems” (weight value is 0.100); the fourth factor is “Planting maintenance” (weight value is 0.081); the fifth factor is “microclimate regulation” (weight value is 0.071). This research could provide references and suggestions for the measurement of vertical greening and weight value distribution to enhance the development of vertical greening, lower the risk assessment and achieve the idea of sustainable management.
