本レビューは、欧州の建物への再生可能エネルギー導入の経済性を技術・地域・政策ごとに比較分析。太陽光発電は住宅で高いIRR（15%超）を示す一方、ヒートポンプの効率は地域によるばらつきが大きく、政策支援の設計と制度能力の重要性を指摘。西・北部欧州と南・東部欧州の導入格差は政策だけでなくガバナンスの有効性に起因する。シミュレーションデータへの過度依存や地域バイアスなど方法論的課題も明らかに。
English
This systematic review compares economic feasibility of renewable energy in European buildings by technology, region, and policy. Solar PV shows high residential IRR (>15%), while heat pump efficiency varies greatly by climate. Hybrid policy mechanisms outperform single instruments, and governance quality matters as much as incentives. North-South adoption gaps persist. Methodological issues include overreliance on simulated data and geographic bias.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
欧州事例に基づくが、日本のZEB・ZEH普及政策や省エネ基準改定において、技術選択と政策設計の両面で示唆がある。特に支援制度のハイブリッド設計や制度運用能力の重要性は、日本の建築物GXに参考となる。
In the global GX context
Provides evidence-based insights for global building decarbonization, emphasizing context-specific policy design (hybrid support mechanisms) and the critical role of institutional capacity—relevant for countries updating NDCs or implementing building energy codes under the Paris Agreement.
👥 読者別の含意
🔬研究者:Highlights methodological gaps (simulation reliance, geographic bias) that future studies on building renewable feasibility should address.
🏢実務担当者:Identify which renewable technologies yield best returns in specific European climates and policy settings for building projects.

📄 Abstract（原文）
<title>Abstract</title> <p>It critically examines the economic feasibility of European building renewable energy deployment, comparing monetary performance variation by technology, region, and policy context, differences in economic outcomes defying assumptions of worldwide viability for renewable energy. Solar photovoltaic systems have superior residential performance with IRRs of more than 15% in well-designed structures, but system size makes a dramatic difference in returns with well-sized installations delivering five times the Net Present Value of conservative practices. Heat pump technologies have high COP ratings of as much as 3.65, but performance is extremely varied in European climate regions in a way that is not adequately explored in current literature. Support mechanisms by government are found to be crucial, with hybrid schemes that draw on various instruments performing better than single-policy mechanisms, but institutional capacity also becomes as important as incentives. Regional analysis reveals long-standing adoption differences between western/northern and southern/eastern European nations that go beyond policy design to the effectiveness of governance. The review identifies critical methodological deficiencies including excessive dependence on simulated data, geographic representation bias, and inconsistent economic evaluation approaches reducing practical application of research findings. Evidence has been confirmed for the economic viability of renewable energy under certain conditions but necessitating context-specific as opposed to generic performance assumptions for successful investment and policy-making choices.</p>
