目前國內既有住宅量較新建多，且普遍面臨整建需求。因此，本研究主要目的是提出適用於臺灣住宅永續整建之未來發展建議。以文獻回顧法與歸納分析法進行「各國政府之相關政策」、「永續整建之研究課題」與「永續整建技術與產品」等三個構面分析。最後依據目前國內住宅整建不永續之問題與政府、學者及業者之發展現況，參考國外文獻來提出國內住宅永續整建之發展建議。研究發現：
國外目前之發展現況
（1）各國政府之相關政策：「推廣手法」以建立知識與技術推廣平台為主。「補助計畫」以貸款補助方式來滿足住戶之最低居住健康。「規範制度」主要針對住宅性能評估外，亦考量住宅未來家庭生命週期變化。（2）永續整建之研究課題：主要以建立決策支援系統為主。（3）永續整建技術與產品：主要以整合產品與技術為主，以增加市場佔有率與推動成效。
臺灣住宅永續整建之問題與落實現況
（1）臺灣住宅永續整建之問題：未考量使用者之需求、管線設備維修不易、綠建材不易推動、過度裝修、住戶與業者僅重視初期成本等影響居住健康與廢棄物等問題。（2）臺灣住宅永續整建之落實現況：政府主要以公寓大廈節能「補助計畫」為主。學者主要研究課題偏向外殼節能、衛浴管線設備之減廢與平面可變性為主。業者技術與產品目前尚無相關技術應用在住宅永續整建範疇上。
臺灣住宅永續整建之發展建議
（1）政府之政策建議：主要以建立知識平台為推廣手法。針對綠建材進行補助與國內既有法令之規範適用性調整。（2）學者之研究建議：協助政府政策推動與業者研發產品與技術，進行全國住宅類型分類、建立決策支援系統與最佳實務。（3）業者之技術與產品建議：參考國外技術與產品，進行適用性調整。

The aim of this research is to propose suggestions for sustainable housing refurbishment in Taiwan base on the current development. The research methods include literature survey and induction. Dealing the current state in oversea countries and Taiwan with three directions, “Government policy”, “Research of sustainable refurbishment”, and “Technique and product of sustainable refurbishing”. The respective current states in overseas and Taiwan are below, and the suggestions for Taiwan are followed.

Current state in overseas
1. Government policy: Promotion policy, popularizing subsidy, and regularization.
2. Research of sustainable refurbishment: Decision-making support system is the goal.
3. Technique and product of sustainable refurbishing: Integration of techniques and products for increasing the market share.

Current state in Taiwan
1. Problem: User's needs are not considered. The equipments and pipeline are difficult to maintenance. Green materials are difficult to impetus. Renovations are excessive. Costs in initial stage are over consideration etc.
2. Current development: “Government policy” is aimed at the promotion policy. “Research of sustainable refurbishment” considers about Energy-conservation of the wall, bathroom facilities and flexibility. “Technique and product of sustainable refurbishing” is under development.

Suggestions for Taiwan
1. Government policy: Building the sustainable knowledge platform, and promotion via it. Subsiding the green building materials. Adjusting current criterion to suitable.
2. Research of sustainable refurbishment: Adjusting the suitable policy with the government. Researching and develop sustainable products and technologies. Carrying on classification of housing type, and then set up to decision-making support system. Celebrating the best practice.
3. Technique and product of sustainable refurbishing: Referring oversea techniques and products, and adjust them suitable.
