都市公寓大廈管委會辦理設施營運維護委外時，常因資訊不對稱而陷入以「價格」為單一標準之採購困境，造成服務品質不穩與建築資產維護失靈。本研究引入服務主導邏輯與ESG框架，以最佳-最差方法（BWM）結合修正型VIKOR（mV）建構「ESG-KPI導向」之設施運維委外評選模型；透過專家訪談萃取22項在地化指標、估算權重與績效差距，並以30位管委會成員進行探索性外部效度檢視。結果顯示，非財務價值（如創新能力、形象與商譽）之重要性排序高於價格，決策呈現由成本導向朝績效導向調整之傾向；惟此係基於探索性樣本，尚未充分控制物管市場之成本僵固性，應解讀為方向性初步證據而非完整驗證之結論。重要性－差距分析（IGA）進一步診斷「創新能力」與「形象與商譽」為核心缺口。據此，本研究提出「門檻審查＋加權評分」之雙軌制評選策略，並建議納入AI智慧客服、雲端工單等科技方案，以提升服務回應效率、緩解人力限制。就建築學門而言，本文將委外評選連結至建築營運階段之生命週期治理、設備妥善率維持與建築延壽決策，其中科技賦能係連結評選結果與建築物理性能之重要機制。

Urban condominium committees often face information asymmetry when procuring outsourced facility operation and maintenance (O&M) services, which drives price-only decisions and may undermine service quality and asset upkeep. Integrating Service-Dominant Logic with an ESG framework, this study develops an ESG-KPI-oriented selection model combining the Best–Worst Method (BWM) with a modified VIKOR (mV). Based on expert interviews, 22 localized indicators were identified to estimate weights and performance gaps, and external validity was explored through a survey of 30 committee members. Results indicate that non-financial values (e.g., innovation capability and reputation/image) ranked above price, suggesting a directional shift from cost to performance orientation. However, this shift rests on an exploratory sample without fully controlling for cost rigidity, and should be read as directional, preliminary evidence rather than a validated conclusion. Importance–Gap Analysis (IGA) identifies “Innovation Capability” and “Reputation and Image” as the most critical gaps. Accordingly, we propose a dual-track strategy combining eligibility screening and weighted scoring, and suggest incorporating technological options—such as AI-enabled customer service and cloud-based work-order systems—to improve response efficiency and alleviate labor constraints. From an architectural perspective, the study links outsourcing evaluation to building lifecycle governance, equipment serviceability, and life-extension decisions during the operation stage. In particular, technological enablement serves as a key mechanism linking selection outcomes to the building’s physical performance.
