隨著台灣快速進入高齡化社會，建築再生成為應對城市發展挑戰的間接密切關係。
老舊建築的功能性、結構安全性及使用效率難以滿足當代需求，因此建築再生不僅能提升建築物的使用壽命，還能促進環境永續發展，並對建築產業的未來形成積極影響。本研究聚焦於小型建設公司在建築再生過程中的角色，探討其如何克服規模限制，透過有效規劃和管理提升市場競爭力。
研究首先回顧國內外建築再生相關的文獻與實務經驗，總結建築再生的定義、方法與發展趨勢。針對小型建設公司特性，透過層級分析法（Analytic Hierarchy Process, AHP）建立評估模型，並邀請專家進行問卷調查，系統化分析企劃、設計、施工及使用階段的關鍵成功因素。本研究也結合案例分析，實地檢驗問卷結果的應用性，進一步提出改善策略。
研究結果顯示，小型建設公司在建築再生領域的成功關鍵包括提升資源整合能力、遵循法規要求並靈活應對政策變化。此外，創新設計與市場需求的準確對接，是提高建築再生效益的核心。本研究強調，小型建設公司需要積極採用跨領域合作模式，以彌補資源不足，並優化營運流程以實現永續發展目標。
本研究的貢獻在於提供一套適用於小型建設公司經營建築再生的評估框架，並提出政策與產業層面的建議，包括完善再生建築的法規體系、建立技術支持平台，以及鼓勵公私協作模式。這些建議旨在推動小型建設公司在建築再生領域的發展，進一步促進台灣建築產業的永續轉型。

This study examines the role of small-scale construction companies in Taiwan's building regeneration, addressing challenges posed by an aging society. Building regeneration not only extends the lifespan of buildings but also promotes environmental sustainability and benefits the future of the construction industry.
The research reviews relevant literature and practical experiences, using the Analytic Hierarchy Process (AHP) to develop an evaluation model. Expert surveys analyze key success factors in planning, design, construction, and usage. Case studies are incorporated to validate findings, resulting in strategic improvement measures.
The study identifies several key success factors for small construction companies: 1) enhancing resource integration to overcome scale and funding limitations, 2) strict adherence to regulations and adaptability to changing policies, and 3) innovative design aligned with market demand. Small companies are encouraged to adopt interdisciplinary collaboration models and optimize workflows to achieve sustainable development.
The study’s main contribution is the development of an evaluation framework tailored to small construction firms involved in building regeneration. The research also offers policy and industry-level recommendations, including improving the regulatory framework, establishing technical support platforms, and promoting public-private collaborations to support small companies’ growth in the regeneration sector.
