快適性と炭素のパラドックス：英国の現代住宅4棟における熱容量・快適性・炭素レジリエンスの居住後評価

日本語
英国の民間住宅4棟を対象に、熱容量・設備・居住者行動が快適性と炭素性能に与える影響を、環境モニタリング・エネルギー使用データ・居住者調査・LCAで分析した。高熱容量の組積造住宅は2022年熱波で温度安定性が高く過熱リスクが低かったが、重量構造と軽量構造のホールライフ炭素差は予想より小さかった。設備更新サイクルと居住パターンが長期排出量に大きく影響し、ネットゼロ住宅には熱レジリエンス・ホールライフ炭素・耐久設備・居住者関与の統合が必要と示す。
English
This study examines how thermal mass, building services, and occupant behaviour affect comfort and carbon performance in four UK private homes (EPC A/B) using monitoring, energy data, surveys, interviews, and LCA. High-thermal-mass masonry homes showed greater temperature stability and lower overheating risk during the 2022 heatwave, while whole-life carbon differences between heavyweight and lightweight construction were smaller than expected. Service replacement cycles and occupancy patterns strongly influenced long-term emissions, indicating net-zero housing requires integrated thermal resilience, whole-life carbon thinking, durable services, and occupant engagement.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本の住宅・建築分野でもZEH・省エネ基準適合義務化や住宅の脱炭素化が進む中、快適性と炭素削減のトレードオフは重要な論点。ホールライフ炭素評価や居住者行動の知見は、国内の建築物ライフサイクルCO2算定や長期優良住宅政策に示唆を与える。
In the global GX context
As global disclosure frameworks (ISSB, CSRD) extend to buildings and embodied carbon, this study offers empirical evidence on the comfort–carbon trade-off and whole-life carbon accounting in residential construction. It contributes to the growing international literature on building decarbonization and climate resilience, relevant to net-zero housing policy and green building standards.

📄 Abstract（原文）
Achieving net-zero housing requires balancing embodied carbon reduction with thermal comfort and climate resilience. This challenge, referred to as the comfort–carbon paradox, remains poorly understood in private residential sector. This study addresses this gap through a novel integration of a mixed-method approach to examine how thermal mass, building services, and occupant behaviour influence both comfort and carbon performance. Four privately developed UK dwellings (EPC A/B), representing masonry, insulated concrete formwork (ICF), and timber-frame construction, were investigated using environmental monitoring, energy-use data, occupant surveys, interviews, and LCA modelling. Results show that high-thermal-mass masonry dwellings achieved greater temperature stability and lower overheating risk during the 2022 heatwave, while whole-life carbon differences between heavyweight and lightweight constructions were smaller than expected. Service replacement cycles and occupancy patterns significantly influenced long-term emissions. The findings demonstrate that net-zero housing requires an integrated approach combining thermal resilience, whole-life carbon thinking, durable services, and occupant engagement.
