南アフリカの住宅建設における炭素排出削減に効果的なグリーンビルディング手法を、実務者インタビューとアンケート調査に基づいて分析。パッシブ・アクティブな省エネ対策、再生可能エネルギー、低炭素材料、水環境配慮設計等の有効性を確認する一方、初期コスト、性能データ不足、政策執行の弱さ、関係者の技能・認識不足が障壁と判明。政策・業界の規制強化、インセンティブ、能力構築が重要と結論。
English
This study examines green building practices for carbon reduction in South African housing through practitioner interviews and surveys. It identifies effective measures such as passive and active energy efficiency, renewable energy, low-carbon materials, and water-sensitive design. Barriers include upfront costs, limited performance data, weak policy enforcement, and lack of skills and awareness. The study concludes that stronger regulations, incentives, and capacity-building are needed.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本の住宅建設でも省エネ・再エネ推進が進むが、南アフリカと共通する初期コスト問題や政策執行の課題は示唆に富む。日本のZEH基準や補助金制度との比較に活用できる。
In the global GX context
This paper adds evidence from a developing-country context on barriers to green building adoption, relevant to TCFD/ISSB's focus on transition risk and opportunity. The identified barriers (upfront cost, data gaps, weak enforcement) resonate with challenges in many emerging economies.
👥 読者別の含意
🔬研究者:Provides indicative insights on green building effectiveness and barriers in South Africa, useful for comparative studies in other developing countries.
🏢実務担当者:Lists specific green building practices (passive design, renewables, etc.) that can be adopted, but notes barriers to consider for implementation.
🏛政策担当者:Highlights the need for stronger regulations, incentives, and capacity-building to overcome barriers and promote low-carbon housing.
📄 Abstract（原文）
The construction sector is a significant contributor to energy consumption and greenhouse gas emissions. This paper examines green building practices that reduce carbon emissions and enhance sustainability in the construction of South African housing. The study adopts a sequential exploratory, qualitative-dominant mixed-methods research approach, comprising semi-structured interviews and an online questionnaire survey, to obtain practitioner perspectives. The study found that passive and active energy-efficiency measures, renewable energy integration, the use of low-emission carbon and recycled materials, water-sensitive design, and waste minimization are effective in reducing operational and embodied CO2. At the same time, the barriers to implementing energy-efficient measures include perceived and real upfront costs, limited local data on performance and returns, weak policy enforcement, and limited skills and awareness among stakeholders. Based on the findings, the study concludes that policy and industry actions involving regulation, incentives for using energy-efficient technologies, and capacity-building/training initiatives can substantially reduce carbon emissions in housing construction, while delivering social and economic co-benefits in line with the Sustainable Development Goals. The study is exploratory and based on a small, practitioner-focused sample, and therefore generates indicative insights rather than statistically generalizable results.
