本報告書は、ポーランド・ルミア、ポルトガル・トーレス・ヴェドラス、ギリシャ・ピレウスの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の脱炭素・エネルギー貧困緩和効果を評価。DREEMエネルギーシミュレーションを用いて、断熱、暖房システム更新、太陽光発電の影響を分析。ヒートポンプが最も費用対効果が高く、特にトーレス・ヴェドラスとピレウスで光熱費50%超削減の可能性を示した。
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 pilot cities: Rumia (Poland), Torres Vedras (Portugal), and Piraeus (Greece). Using DREEM energy simulations, it evaluates insulation, heating system upgrades, and photovoltaic installations. Heat pumps emerged as the most cost-effective solution, with potential energy bill reductions exceeding 50% in Torres Vedras and Piraeus.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
EUの集合住宅改修政策の実証分析であり、日本の既存住宅ストック改修促進策（例：省エネ基準適合義務化、補助金制度）の設計や、エネルギー貧困対策の参考となる。特にヒートポンプ導入効果の定量評価は、日本のZEH・ZEB推進にも示唆を与える。
In the global GX context
This study provides empirical evidence on cost-effective building renovation measures for decarbonisation and energy poverty mitigation, relevant to global efforts under the Paris Agreement and EU Energy Performance of Buildings Directive. The methodology and findings can inform similar analyses in other regions, including Japan's building stock renovation strategies.

📄 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.
