この論文は、英国のネットゼロ目標達成に向けた既存建築物の改修において、デジタルツイン（DT）システムが全ライフカーボン（WLC）評価にどのように活用できるかを体系的にレビューした。PRISMAガイドラインに従い42の学術論文と20の政策文書を分析し、現在のDT研究は運用カーボンに偏り、体現カーボンやWLC統合が未発達であることを明らかにした。また、DT-WLC統合のための5層フレームワークを提案し、政策との整合性や相互運用性の向上の必要性を指摘した。

This paper systematically reviews the use of digital twin (DT) systems for whole-life carbon (WLC) assessment in UK building retrofit towards net-zero targets. Analyzing 42 academic papers and 20 policy documents via PRISMA, it finds current DT research overemphasizes operational carbon while neglecting embodied carbon and full WLC integration. The study proposes a five-layer DT-WLC integration framework and identifies gaps in retrofit-specific applications, policy alignment, and dynamic-static database integration.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
英国のネットゼロ政策と建築ストック改修に焦点を当てたレビューであり、日本でもSSBJや有報における建築物のGHG開示が進む中、デジタルツインを活用した全ライフカーボン評価の枠組みは日本の不動産・建設業界にとっても示唆に富む。特に、運用カーボンと体現カーボンの統合的な評価や政策連動の重要性は、日本の建築物省エネ基準やZEB/ZEH施策にも応用可能である。
In the global GX context
This paper provides a comprehensive review of digital twin applications for whole-life carbon assessment in UK building retrofit, highlighting the imbalance between operational and embodied carbon integration. For global GX context, it addresses the gap between dynamic DT systems and static LCA databases, which is relevant to ISSB and CSRD disclosure requirements for built-asset carbon. The proposed five-layer framework could inform international standards for digital carbon assessment in existing buildings.
👥 読者別の含意
🔬研究者:The paper identifies four key research gaps and proposes a conceptual DT-WLC framework, offering a roadmap for future studies on integrated carbon assessment in retrofit.
🏢実務担当者:Real estate and construction firms can use the policy-aligned gaps and framework to evaluate digital twin investments for full lifecycle carbon tracking in retrofit projects.
🏛政策担当者:UK policymakers should note the limited alignment between current DT research and retrofit policy instruments, and the need for standards that integrate embodied carbon assessment into DT systems.
📄 Abstract（原文）
Introduction Buildings and construction contribute substantially to global and United Kingdom carbon emissions, and achieving net-zero targets requires accelerated retrofit of the existing building stock. Digital Twin (DT) systems are increasingly promoted for real-time monitoring, predictive analytics and lifecycle performance optimisation, yet their ability to support whole-life carbon (WLC) assessment in United Kingdom retrofit contexts remains unclear. Methods This study conducted a PRISMA-guided systematic literature review and policy analysis of 62 sources, comprising 42 peer-reviewed academic papers and 20 United Kingdom government, parliamentary and industry documents. Sources were drawn from Scopus, Web of Science, ScienceDirect and Google Scholar. The review used quality appraisal and thematic analysis to examine DT capabilities across EN 15978 lifecycle modules, RICS Whole Life Carbon Assessment requirements and United Kingdom retrofit policy instruments. Results The findings show that current DT research is strongly weighted towards operational carbon, while embodied carbon and full WLC integration remain underdeveloped. Many systems described as digital twins function more closely as digital shadows with limited or one-way data flows. Reported energy-saving claims are often based on well-instrumented commercial buildings and are not always transferable to the heterogeneous domestic retrofit stock that dominates the United Kingdom's net-zero challenge. Retrofit-specific DT applications remain limited despite the importance of existing buildings in the 2050 stock. Discussion Four main gaps are identified: the absence of integrated DT-WLC frameworks across all EN 15978 modules, the underrepresentation of retrofit-focused DT research, limited alignment with United Kingdom policy and standards, and weak integration between static lifecycle assessment databases and dynamic DT systems. The paper proposes a conceptual five-layer DT-WLC integration framework and a policy-aligned research agenda to support future validation, interoperability and retrofit-scale implementation.
