日本語
本論文は、南アフリカを事例に、グローバル・サウスにおける手頃な価格の住宅とネットゼロカーボン目標の統合を検討。混合手法を用いて、住宅のライフサイクル炭素排出量を分析し、パッシブ設計と太陽光発電の導入により運用排出をほぼゼロにできることを示した。ただし、太陽光パネルによる体化炭素の増加も指摘。
English
This study investigates how affordable housing in South Africa can transition to net-zero carbon. Using mixed methods including life cycle assessment, it finds that combining passive design with on-site PV can reduce lifecycle emissions by up to 94%, nearly eliminating operational emissions. However, PV installation increases embodied carbon. The paper provides a roadmap for affordable net-zero carbon housing in coal-reliant economies.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本の住宅分野では、断熱性能向上や太陽光発電の義務化が進むが、本論文のようなライフサイクル全体での炭素評価や途上国との比較は参考になる。ただし、日本の住宅市場や気候条件は異なるため、直接適用には注意が必要。
In the global GX context
This paper offers a rare integration of affordability and net-zero carbon in the Global South context. Its focus on coal-reliant economies and whole-life carbon assessment provides lessons for emerging economies transitioning to low-carbon housing. It complements global discussions on just transition and building decarbonization.

📄 Abstract（原文）
Affordable housing and climate mitigation are often addressed separately rather than together in the Global South. Limited research exists integrating affordability with net-zero carbon objectives in housing under resource-constrained conditions. This paper investigates how affordable housing in South Africa can transition towards net-zero carbon, and what trade-offs and pathways are credible under local market, regulatory and energy system constraints. An exploratory mixed-methods design combined semi-structured interviews with whole life cycle carbon emission (WLCCE) modelling of a typical three-bedroom house. Four experts in the affordable and sustainable housing space were interviewed and analysed thematically to identify perceptions, challenges, and opportunities. The WLCCE integrated One Click life cycle assessment (embodied carbon) and Excellence in Design for Greater Efficiencies (EDGE) (operational carbon) to test three affordable net-zero carbon housing (ANZCH) scenarios. The findings show operational emissions dominate the WLCCE in the base case. Prioritising envelope efficiency plus on-site photovoltaic (PV) can reduce WLCCE by 12–94% relative to a conventional baseline. The innovative ANZCH pathway achieved near elimination of operational emissions but raised embodied impacts through PV installation. This study offers developers a roadmap for ANZCH in coal-reliant economies, prioritising operational carbon reduction, passive design and scalable technologies within cost-effective strategies. Achieving ANZCH in the Global South requires passive design, efficient building systems and scalable PV installations, supported by low-carbon materials. The research informs sustainable housing strategies, balancing affordability and carbon mitigation in coal-reliant economies.
