建築物外牆整建利益關係人存在競合關係，如何了解不同關係人對相關問題的看法，藉以整合出適當的外牆管理機制，達到改善都市環境與市容觀瞻的目的，是本研究所探討一個主要的課題。本研究透過臺北市政府推動建築物整建案例分析，了解目前整建維護的需求與實施情形，再藉由建築師、營造業、公寓大廈管理委員會與主管機關進行深度訪談，並以建築物生命週期之「規劃」、「施工」、「使用」三個構面建立影響關鍵因素與問卷，進行調查分析；依研究結果顯示，建築師著重於外牆之規劃與使用機能、營造業重視工期與安全防護、公寓大廈管理委員會重視整建後使用功能及訂定管理維護規範、公部門則在規劃設計偏重綠色環保建築。因此，政府部門推動外牆整建的管理機制在政策面可採以獎勵補助為誘因，吸引民眾參與；在制度面則可透過建築師、營造業與公寓大廈管理委員會辦理專業簽證負責，透過專業管理，達到提昇外牆整建的整體品質，最後訂定整建完成後的管理、維護與分擔維修經費等法令規範，達到永續使用之目標；相關研究成果可提供政府作為推動整建維護管理機制之參考與建議。
