日本語

欧州の気候帯における既存建物改修の緩和・適応戦略をPRISMA-ScRに沿って118件の文献から整理したレビュー。改修効果は気候・地域条件で異なり、外皮改善・日射制御・パッシブ冷却・選択的アクティブ技術の組合せが単独施策より有効。エネルギー効率・温熱快適性・環境影響のトレードオフが存在し、気候帯の偏りやシミュレーション依存が研究課題として指摘される。

English

A PRISMA-ScR review of 118 studies on building retrofit across European climate zones, with 48 assessed in detail for mitigation-adaptation strategies. Retrofit performance varies by climate; combined envelope, solar control, passive cooling and selective active measures outperform isolated ones. Trade-offs among energy efficiency, thermal comfort and environmental impact persist, and research suffers from climate-zone imbalance and simulation reliance.

📝 gxceed 編集解説 — Why this matters

日本のGX文脈において

国内でも省エネ改修・ZEH/ZEB化はGX推進の柱であり、適応策との統合や気候帯別の効果差は建築物の脱炭素投資判断や自治体の適応計画に示唆を与える。

In the global GX context

Building retrofit sits at the core of EU decarbonization policy (EPBD, Renovation Wave) and the review's mitigation-adaptation framing speaks to CSRD/TCFD physical-risk disclosure and transition planning for real estate portfolios.

📄 Abstract（原文）

Retrofitting existing buildings can contribute to both climate change mitigation and adaptation, yet their interaction has received limited attention across several climatic contexts. This state-of-the-art review investigates retrofit strategies for the existing building stock in European climate zones. The screening process followed PRISMA-ScR guidelines and used Scopus as the database, with three researchers independently assessing the retrieved studies. After screening, 118 publications were analysed to identify research trends, while 48 were selected for detailed assessment of adaptation and mitigation retrofit strategies. The findings show that retrofit performance varies with climate and local conditions. For climate-responsive design, passive measures are still central, although their abiding effectiveness often depends on integration with active systems. Therefore, combinations of envelope improvements, solar control, passive cooling, and selected active technologies appear more effective than isolated measures. These strategies may also involve compromises between energy efficiency, thermal comfort, and environmental impact under present and future climates. The review identifies climate-specific relationships between retrofit measures and adaptation–mitigation outcomes. Current research is affected by climate zone coverage imbalance, insufficient attention to climate-induced hazards, and reliance on simulations. Further investigations should strengthen experimental assessment and adopt multi-hazard approaches considering durability, economic feasibility, and vulnerability.
