本研究は、EUの建築ストックの脱炭素化進捗を評価し、エネルギー性能と再生可能エネルギー統合のギャップを明らかにした。住宅は年3%の改善が必要で、非住宅は現在の2.7%の改修率を維持する必要がある。再生可能エネルギーは年2.8%の増加が必要であり、指標の調和、データ品質向上、改修促進が重要と結論付けた。
English
This study assesses the EU's progress towards a decarbonised building stock, revealing significant gaps in energy performance and renewable integration. Residential buildings need a 3% annual improvement, while non-residential must maintain current 2.7% renovation rates. Renewable generation must increase by 2.8%/year to meet 2050 demand. The study calls for harmonised indicators, better data, and accelerated renovation rates.

日本のGX文脈において
日本の建築物省エネ基準やZEH/ZEB普及政策と比較可能な知見を提供。特に既存ストックの改修促進や指標の調和は、日本の省エネ性能表示制度や住宅トップランナー制度の強化に示唆を与える。
In the global GX context
This study provides a comprehensive assessment of EU building decarbonisation, offering insights for global policy frameworks like the EU Energy Performance of Buildings Directive and the Renovation Wave. It highlights the need for harmonised indicators and data quality, which are relevant for ISSB and CSRD reporting on building-related emissions.
👥 読者別の含意
🔬研究者:Provides quantitative benchmarks for building energy performance and renewable integration in the EU, useful for comparative studies.
🏢実務担当者:Highlights renovation rate targets and renewable generation needs that could inform corporate building portfolio strategies.

📄 Abstract（原文）
ABSTRACT With the building sector accounting for 30% of global emissions (40% with embodied emissions), this study assesses the progress of the European Union (EU) towards a decarbonised building stock. In line with national Nearly Zero-Energy Building (NZEB) requirements, energy performance and renewable integration are evaluated. Significant gaps are found in both areas. Residential buildings require the most substantial improvements in energy performance – a decline of 3 % per year – while non-residential buildings need to maintain current upgrading rates of 2.7 % per year. Although higher compliance is observed regarding renewable energy use as compared with energy performance, generation must increase by 2.8%/year to cover the energy demand in 2050. The study highlights the need to harmonise indicators, enhance data quality, revise national thresholds, and accelerate renovation rates to achieve widespread energy savings in the existing building stock. Additionally, it emphasises the importance of addressing both operational and embodied emissions, incorporating circularity strategies and Life Cycle Assessment to inform balanced decision-making. These findings offer valuable insights for policymakers to define coherent requirements and roadmaps for climate neutrality. A holistic approach—encompassing energy efficiency, behavioural change, low-carbon materials and clean energy adoption—is essential to the EU’s transition towards a decarbonised building environment, with affordable and sustainable living spaces.
