オーストラリアのオフィス内装改修で生じる大量の廃棄物・ embodi炭素を背景に、循環型実践の導入が国内文脈条件にどう左右されるかを質的システムダイナミクスで分析。専門家フォーカスグループから因果ループ図を構築し、政策・市場・インフラ・社会文化・組織・バリューチェーンの各条件が相互作用する多層メカニズムを提示した。参加者提案の介入策を因果構造上の標的点にマッピングしている。
English
Using qualitative system dynamics and expert focus groups, this study examines how Australian contextual conditions shape circular practices in office fit-outs. It builds a causal loop diagram revealing a multi-level architecture where policy, market, infrastructure, socio-cultural, organisational and value-chain conditions interact to enable or constrain circular building design, product design and business models. Proposed interventions are mapped to causal leverage points.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
Scope 3・ embodied carbon 開示が進む日本でも、テナント退去時の原状回復慣行や賃貸契約構造が循環性を制約する点は示唆的。建設・不動産セクターの脱炭素戦略やサーキュラー調達の議論に文脈的視点を提供する。
In the global GX context
As CSRD and ISSB push embodied-carbon and circularity disclosure into scope, this paper shows why circular construction transitions are context-dependent and cannot be reduced to generic best-practice checklists. It offers a transferable mechanism-based method for contextualising circularity in other national value chains.
👥 読者別の含意
🔬研究者:循環建設トランジションを文脈依存のメカニズムとして捉える質的システムダイナミクス手法の応用例として参考になる。
🏢実務担当者:内装・原状回復慣行が循環調達や廃棄物削減の制約になる構造を理解し、介入設計に活かせる。
🏛政策担当者:廃棄物・循環政策が市場・契約慣行とどう相互作用するかを踏まえた政策設計の視点を提供する。
📄 Abstract（原文）
Office fit-outs generate substantial material waste and embodied carbon, largely due to frequent alterations driven by lease turnover, make-good obligations, organisational changes, workplace reconfigurations, and evolving aesthetic expectations. Although circular practices and supporting collaboration structures have been identified, limited understanding exists of how their implementation is shaped by specific national contexts. This study contextualises these practices and collaboration structures by examining how Australian contextual conditions influence their implementation through interacting mechanisms. A Qualitative System Dynamics approach was employed through expert focus groups with operational and strategic stakeholders across the Australian office fit-out sector. Stakeholder knowledge was translated into a Causal Loop Diagram and analysed through pathway analysis to identify mechanisms influencing Circular Building Design, Circular Product Design, and Circular Business Models. The findings reveal that contextual conditions do not operate as isolated barriers or enablers but interact through a multi-level architecture comprising core implementation and broader contextual mechanisms. Together, these mechanisms explain how policy, market, infrastructure, socio-cultural, organisational, and value-chain conditions enable, constrain, and reshape circular implementation. The study also maps participant-proposed interventions to the specific points within the causal architecture that they are intended to target. Although the resulting model represents a participant-informed qualitative dynamic hypothesis that neither estimates causal effect sizes nor ranks mechanisms or interventions, the study offers an analytical approach for contextualising circular transitions that may be adapted and tested in other construction contexts.
