近年來因氣候變遷、極端氣候及人類的活動增加，導致全球水資源缺乏，許多人飽受缺水之苦，水資源再利用成為全球關注的重要課題。在綠色建築與永續環境議題上，植生牆被應用在建築外牆以調節氣候、緩解都市熱島效應、增加綠化、生物多樣性、減少空調耗能上之益處已被認同。在先前的研究中植生牆結合人工溼地，應用自然淨化機制處理生活雜排水的效能已被證明，但淨化植生牆系統(PGWS)原型整體重量過重無法一個人安裝完成，且更換介質、植栽不方便且植栽覆蓋面積不足。本研究蒐集整理綠牆系統分類、淨化植生牆淨水原理、綠牆覆蓋率算方法及各類型建築物用水狀況，掌握相關基礎理論後進行實驗設計與單元優化與數據分析。針對垂直流淨化型植生牆系統進行實驗驗證，其同樣具有去除汙染物、淨化雜排水效果。進一步對水平流、垂直流淨化型植生牆設置單元與系統進行優化操作，提升設置方便性和維護管理之便利性，在設置單位面積內提升淨化植生牆之綠覆比例與淨水效益，增加植栽與介質更換之便利性。其植栽覆蓋率經過優化後亦得到提升，植栽覆蓋率為垂直流大於水平流與PGWS原型。評估淨化植生牆應用於各類型建築中之節水效益，回收用水的自來水替代比例最高為休閒類建築，其次為宿舍類建築，第三為公共類建築，提供各類型建築物導入淨化型植生牆之效益評估依據。在不同的設置空間條件中，依照空間特性選擇垂直流或水平流系統設置，以達到設置最大效益。

In recent years, due to climate change, extreme weather and human’s activities, leading to the lack of global water resources, many people suffer from water, and the reuse of water resources has become an important issue of global concern. On the issues of green building and sustainable environment, the green-wall has been applied to the external walls of buildings to regulate the climate, alleviate the urban heat island effect, increase greening, biodiversity, and reduce the energy consumption of air conditioning. In the previous research, the effectiveness of the green-wall combined with the constructed wetland to apply the natural purification mechanism to treat domestic sewage has been proved, but the weight of the PGWS prototype is too heavy to be installed by one person. And it is inconvenient to replace the medium and planting, green area is not enough. This research collects and sorts the classification of green-wall system, the principle of water purification of green-wall, the calculation method of green-wall coverage, the water usage of various types of buildings, and the experimental design, unit optimization and data analysis after mastering relevant basic theories. The experimental verification of the vertical flow purification plant wall system also has the effect of removing pollutants and purifying sewage. Optimize the installation unit and system of horizontal flow and vertical flow purification green-wall, improve the convenience of installation and maintenance management, improve the green coverage ratio and water purification efficiency of the purification plant wall in the unit area, increase planting and convenience of medium replacement. The green coverage rate has also been improved after optimization. The green coverage ratio of vertical flow is better than horizontal flow greater and PGWS prototype. This research evaluated the water-saving benefits of the purification green-wall in various types of buildings. The highest proportion of tap water replacement for recycled water is leisure buildings, followed by dormitory buildings, and the third is public buildings. In different installation space conditions, the vertical flow or horizontal flow system settings can be selected according to the spatial characteristics to achieve the maximum benefit of the installation.
