日本語
本論文は、英国の住宅セクターの脱炭素化に向けて、循環経済（CE）原則を既存の改修手法に統合することを提案する。断熱材や暖房システムの更新といった技術的解決策に偏った現在の政策に対し、材料の循環性、廃棄物削減、ライフサイクル評価を重視した枠組みを提示。政策分析、ステークホルダー協議、実証評価を通じて、規制・人材・サプライチェーンの障壁を特定し、エネルギー効率向上と環境持続可能性の両立を図る意思決定支援フレームワークを提供する。
English
This paper advocates integrating Circular Economy (CE) principles into the retrofitting of post-1950 UK housing stock to accelerate decarbonisation. It critiques current policies focusing narrowly on technological fixes (insulation, heating) and proposes a framework emphasizing material circularity, waste minimization, and lifecycle assessment. Through mixed methods including literature review, policy analysis, stakeholder engagement, and case evaluations, it identifies key barriers (regulatory, workforce, supply chain) and enablers. The resulting evidence-based framework guides policymakers and practitioners toward holistic retrofit strategies that improve energy efficiency, reduce embodied emissions, and enhance sustainability.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本では住宅の省エネ改修が進むが、循環経済の視点はまだ乏しい。本論文のフレームワークは、日本の住宅ストック（特に高度成長期以降の建物）にも応用可能で、SSBJやESG情報開示におけるスコープ3（建設・廃棄段階）の削減にも貢献し得る。英国特有の規制・人材課題を参考に、日本版の統合的改修戦略を検討する際の示唆となる。
In the global GX context
This research is timely for global GX practice as it moves beyond siloed energy-efficiency upgrades toward a circular, lifecycle approach to building decarbonization. It aligns with ISSB standards and TCFD recommendations on value-chain emissions (including embodied carbon) and provides a transferable framework that can inform policy development in regions tackling aging housing stock. The mixed-methods evaluation of barriers and enablers offers empirical grounding for transition finance in the real estate sector.
👥 読者別の含意
🔬研究者:Provides a comprehensive mixed-methods framework for integrating circular economy into retrofit research, with barrier and enabler analysis applicable to other contexts.
🏢実務担当者:Offers a decision-making framework to guide contractors and developers in implementing circular retrofit strategies that balance energy efficiency, material reuse, and cost.
🏛政策担当者:Highlights regulatory and workforce gaps that need addressing to scale circular housing retrofits, and provides evidence for designing integrated policy packages.
📄 Abstract（原文）
The UK’s net-zero by 2050 commitment necessitates urgent housing sector decarbonisation, as residential buildings contribute approximately 17% of national emissions. Post-1950 construction prioritised speed over efficiency, creating energy-deficient housing stock that challenges climate objectives. Current retrofit policies focus primarily on technological solutions—insulation and heating upgrades—while neglecting broader sustainability considerations. This research advocates systematically integrating Circular Economy (CE) principles into residential retrofit practices. CE approaches emphasise material circularity, waste minimisation, adaptive design, and a lifecycle assessment, delivering superior environmental and economic outcomes compared to conventional methods. The investigation employs mixed-methods research combining a systematic literature analysis, policy review, stakeholder engagement, and a retrofit implementation evaluation across diverse UK contexts. Key barriers identified include regulatory constraints, workforce capability gaps, and supply chain fragmentation, alongside critical transition enablers. An evidence-based decision-making framework emerges from this analysis, aligning retrofit interventions with CE principles. This framework guides policymakers, industry professionals, and researchers in the development of strategies that simultaneously improve energy-efficiency, maximise material reuse, reduce embodied emissions, and enhance environmental and economic sustainability. The findings advance a holistic, systems-oriented approach, positioning housing as a pivotal catalyst in the UK’s transition toward a circular, low-carbon built environment, moving beyond isolated technological fixes toward a comprehensive sustainability transformation.
