日本語
EUの単一家族住宅を対象に、形状・規模・建設材料がembodied CO2eに与える影響を3.5万超の設計シナリオで分析。ANOVAやKruskal–Wallis検定、C&RT決定木を用い、単位排出量と生涯排出量の両面から住宅特徴の重要度を順位付けした。評価には生涯排出量を用いるべきとの提言を導出・実証している。
English
Analyzing over 35,000 design scenarios of EU single-family houses, this study quantifies how building shape, size and material choice drive embodied CO2e. Using ANOVA, Kruskal–Wallis tests and C&RT decision trees, it ranks feature importance for both per-m²/year and life-long emissions. It argues building assessments should adopt life-long emissions to better achieve sustainability.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
EUの建物embodied排出量規制(EPBD改訂)を背景に、日本でもSSBJ・Scope3のCat.1/2や建設業の脱炭素開示、住宅会社のLCA対応を検討する際の定量手法として参考になる。
In the global GX context
Aligns with the EU EPBD's shift toward whole-life carbon limits and the growing ISSB/CSRD demand for Scope 3 building emissions; offers a replicable method for ranking design levers in embodied-carbon disclosure.
👥 読者別の含意
🔬研究者:建物embodied排出量の設計変数感度を大規模シナリオで定量化した手法と生涯排出量指標の妥当性を参考にできる。
🏢実務担当者:住宅・建設のLCA担当が、形状・材料選択と生涯排出量評価を設計段階の脱炭素意思決定に組み込む根拠になる。
🏛政策担当者:建物のwhole-life carbon規制や評価指標設計で、単位排出量ではなく生涯排出量を採用する根拠として参照できる。
📄 Abstract(原文)
The embodied emissions of buildings are expected to be limited in European Union (EU) countries; while the energy consumption of buildings is decreasing, their material footprint is becoming more significant. This article presents the results of the analysis of the embodied emissions of single-family houses, depending on their shape features and the types of construction materials used. Analysis of variance (ANOVA), Shapiro–Wilk’s test, the Kruskal–Wallis test, and Classification and Regression Trees (C&RT) are used to analyze a deterministic design-space database comprising over 35 thousand calculated scenarios and rank the importance of the houses’ features. The unit emissions (per square meter, per year) and life-long emissions of the houses are analyzed and discussed, considering the areas of the houses, their shapes, and the materials used for their construction. In planning to limit CO2e embodied emissions, the recommendation to use life-long emissions in building assessments (to achieve better sustainability) is worked out and proved.
