本報告書は、ポーランド、ポルトガル、ギリシャの3都市における民間集合住宅の改修と再生可能エネルギー導入が、脱炭素化とエネルギー貧困緩和に与える影響を評価。DREEMシミュレーションを用いて、断熱、暖房システム更新、太陽光発電の効果を分析した結果、ヒートポンプが最も費用対効果が高く、光熱費を50%以上削減できることが示された。断熱は古い建物で有効だが費用対効果は低く、バイオマスやガスボイラーも低性能建物で効果的。太陽光発電は技術的制約があるものの費用対効果は良好。脆弱世帯向けの対策特定や自治体の政策立案に貢献する。
English
This report assesses the potential of building renovation and renewable energy integration for decarbonisation and energy poverty reduction in private multifamily buildings across three European pilot cities. Using DREEM simulations, it finds heat pumps most cost-effective, reducing energy bills by over 50%. Thermal insulation benefits older buildings but is less cost-effective. Biomass and gas boiler upgrades help in low-performing dwellings. Photovoltaics show favorable cost-effectiveness despite constraints. The findings support targeted policies for vulnerable households and local climate strategies.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本では、既存住宅ストックの省エネ改修がGX実現の鍵とされるが、エネルギー貧困の視点はまだ十分に議論されていない。本報告書のヒートポンプや太陽光発電の費用対効果分析は、日本の集合住宅向け補助金設計や自治体の気候戦略に示唆を与える。
In the global GX context
This study provides empirical evidence on cost-effective renovation measures for multifamily buildings, linking decarbonisation with energy poverty mitigation. It offers transferable insights for EU and global policies targeting building stock decarbonisation, especially for vulnerable households. The multi-city comparison strengthens the case for heat pump deployment and targeted subsidies.
👥 読者別の含意

🏢実務担当者:Offers cost-effectiveness rankings (heat pumps > PV > insulation) to guide renovation programs for multifamily buildings.
🏛政策担当者:Supports design of targeted energy poverty mitigation policies and local climate strategies with evidence from three European cities.
📄 Abstract（原文）
This report examines the potential of building energy renovation and renewable energy integration to support decarbonisation and reduce energy poverty in private multifamily buildings. The analysis covers three pilot cities: Rumia (Poland), Torres Vedras (Portugal), and Piraeus (Greece). Using DREEM energy simulations for representative dwelling typologies, the study assesses the impact of insulation, heating system upgrades, and photovoltaic installations on energy demand, carbon emissions, and energy bills. Heat pumps emerged as the most impactful and cost-effective solution, particularly in Torres Vedras and Piraeus, with potential energy bill reductions exceeding 50%. Thermal insulation showed lower cost-effectiveness but remained beneficial for older and low-performing buildings. Biomass and gas boiler upgrades delivered meaningful savings in less efficient dwellings, while photovoltaic systems demonstrated favourable cost-effectiveness despite technical constraints. The findings help identify the most suitable measures for vulnerable households and provide evidence to support municipalities in designing targeted energy poverty mitigation policies and more effective local climate strategies.
