摘要

立面綠化具有許多環境效益，而日漸受到重視，近年來立面綠化技術不斷的推陳出新，以為客戶提供更多優勢，迄今市場上已有許多不同的垂直綠化產品。為了向開發/代理廠商提供更多訊息，本研究探討立面綠化產品開發考量因素、立面綠化技術的系統性歸類、以及不同立面綠化系統之降溫效益觀測。研究結果指出，各家廠商在開發/代理新產品時，皆會多方考量，整體而言，以施工便利、構圖細緻、造價低、低維護管理、美觀、植栽生長良好、自動澆灌系統、提昇附加價值為主要考量因素。立面綠化系統可歸類為九大系統，包括：單體式獨立滴灌型、單體式獨立澆灌型、區塊式獨立滴灌型、區塊式獨立澆灌型、植生毯型、支架攀爬型、簡易盆栽型、單體式虹吸型、直接攀爬型。針對立面綠化系統，進行實地降溫效益觀測，結果顯示，立面綠化系統皆有明顯的降溫效果，而不同系統間存在降溫效果差異，以區塊式獨立澆灌型、單體式獨立澆灌型、直接攀爬型較佳，而系統綠覆率愈高，系統表面溫度、系統覆蓋下方牆面溫度愈低。

Vertical greening, which provides multiple environmental benefits, has got more and more attention. In recent years, vertical greening technology has been constantly innovated to provide customers with more advantages. To date, there are many diverse vertical greening products on the market. To provide more information for R&D suppliers/distributors, this study investigated the factors considered when developing/introducing a new vertical greening product, systematic categorization for vertical greening technology, and temperature reduction effect of different vertical greening systems. Study results showed that R&D suppliers/distributors considered several factors while creating/introducing a new vertical greening product. Overall, workability, composition fineness, low construction cost, low maintain requirement, aesthetics, plant growth well, auto-irrigation, and added benefit were the main considerations for R&D suppliers/ distributors. Nine vertical greening systems (VGS) were categorized, including planter boxes with drip irrigation system, planter boxes with irrigation system, panel with drip irrigation system, panel with irrigation system, geotextile felt system, supported climbing system, simple potted system, planter boxes with siphon system, and direct greening system. Respect to temperature reduction effect observation for 8 VGSs, all VGSs had significant temperature reduction effects. Different VGSs had significantly varied temperature reduction effects. Panel with irrigation system, panel with irrigation system, and direct greening system were observed to have a greater temperature reduction effect. For VGSs with higher green coverage ratio tended to have lower system surface temperature and wall surface temperature.
