📄 Abstract（原文）
The construction sector is a major contributor to resource depletion and environmental emissions, necessitating the transition toward Circular Economy (CE) strategies aligned with Sustainable Development Goals (SDGs). Life Cycle Assessment (LCA) is widely applied to evaluate environmental performance; however, conventional approaches often lack the dynamic, digital, and multi-scale capabilities required to assess circular systems effectively. This study systematically reviews 61 peer-reviewed articles published between 2019 and 2025 to examine the integration of CE and LCA in the building sector. The selected studies were classified based on LCA methodology, CE strategy, system boundary, scale of application, and use of digital tools. A critical thematic synthesis reveals a growing shift toward dynamic, parametric, and hybrid LCA approaches, enabling improved representation of reuse cycles, material recovery, and lifetime extension. However, the findings also demonstrate that results are highly sensitive to methodological assumptions, particularly system boundaries, allocation rules, and service life parameters, which are often insufficiently validated. While CE strategies such as reuse, recycling, bio-based materials, and design for disassembly generally show environmental benefits, their effectiveness is context-dependent and may be overstated under idealized scenarios. Digital tools, including BIM, digital twins, and AI-based models, enhance data traceability and scenario analysis but remain constrained by interoperability challenges, data limitations, and limited large-scale implementation. Overall, the review identifies a gap between methodological advancement and practical robustness, highlighting the need for standardized modeling frameworks, improved uncertainty treatment, and integrated multi-dimensional sustainability assessment to support reliable CE–LCA applications.
