建物のコンパクト性と建設年代をプロキシとして、全球の建物エネルギー効率を評価。老朽化した建物や気候に不適切な形状の地域に約4800万人が居住し、今後増加する可能性を指摘。低所得国では軽量で非コンパクトな都市拡大が気候変動への適応を困難にし、エネルギー需要増加と熱的快適性の確保に課題をもたらす。
English
Using building compactness and construction epoch as proxies, this study assesses global building energy efficiency and identifies vulnerable areas home to 48 million people, potentially increasing by 10-30% by 2100. It reveals stark disparities across income levels, with low-income countries facing greater climate adaptation challenges due to recent, lightweight urban expansion.

日本のGX文脈において
日本の建築ストックは省エネ基準の強化が進むが、既存建物の改修が課題。本研究成果は、気候変動下での建物エネルギー効率向上と適応策の優先地域特定に示唆を与え、国土交通省の建築物省エネ政策や自治体の気候適応計画に活用可能。
In the global GX context
This study provides a global baseline for building energy efficiency and climate vulnerability, relevant for international climate adaptation and mitigation strategies. It highlights the need for targeted retrofitting and resilient urban planning, informing global frameworks like the Paris Agreement and sustainable development goals.

📄 Abstract（原文）
Building compactness and construction epoch are relevant proxies of energy efficiency in buildings. By integrating building stock and Earth observation data, we characterize buildings globally and identify vulnerable areas dominated by old building age and unsuitable compactness in relation to climate conditions. Such areas are home to a population of 48 million persons that could increase by 10% to 30% by 2100 under likely socioeconomic pathways, shifting from cold regions of Eurasia to the heat-prone Sahel zone, Gulf countries and Pakistan. Results reveal stark disparities in building energy efficiency across income levels, urbanization patterns, and climate zones. Almost half of buildings globally (i.e., 43%) were built before 1980, when few to no energy efficiency measures existed, and these buildings are concentrated mainly in temperate and cold-climate urban areas in high-income countries. Low-income countries experienced more recent, lightweight and less compact urban expansion, which exposes them to the forecasted climate warming: this could increase their energy demand, hinder climate adaptation and imposes further challenges to ensure affordable thermal comfort for all.
