📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本の建設・不動産分野では、既存ストックの活用が喫緊の課題であり、本枠組みは改修時の脱炭素・循環性向上に寄与する。SSBJ開示や投資家対応においても、建物の環境性能向上は重要であり、実務的な参考となる。
In the global GX context
Globally, the built environment is a major carbon source, and adaptive reuse is key to reducing embodied carbon. This framework provides a replicable model for integrating circular economy principles into retrofit projects, aligning with global net-zero targets and sustainability disclosure frameworks like TCFD and ISSB.

📄 Abstract（原文）
This study investigates how Circular Economy (CE) strategies and principles can be systematically integrated across the lifecycle of Adaptive Reuse and Retrofit Projects (ARRPs) to support the low-carbon transformation of underutilized existing buildings (UEBs). While existing literature often focuses on end-product outcomes, it lacks a systematic approach for prioritizing CE principles across different project stages. Addressing this gap, the study applies the ReSOLVE framework and a Delphi method involving 19 international experts in adaptive reuse, sustainability, and heritage conservation. A mixed-methods approach combining expert elicitation, Fuzzy Synthetic Evaluation (FSE), and action mapping was used to identify and prioritize CE strategies across five lifecycle stages: Assessment, Planning and Design, Retrofitting, Operation, and Evaluation. The results highlight Optimize, Regenerate , and Exchange as the most consistently prioritized principles, with Optimize emerging as the most influential overall. The study presents a lifecycle-based decision-support framework populated with expert-informed, actionable interventions aligned with each CE principle and project phase. These interventions provide practical guidance for improving sustainability performance during the execution of ARRPs in UEBs. The research contributes a replicable model for CE strategy deployment in the built environment and offers insights for practitioners, policymakers, and researchers seeking to align adaptive reuse and retrofit with circularity and net-zero carbon objectives.
