日本語

本研究は、南アフリカのケープタウンにあるUlwazi Educare Centreの事例を通じて、コミュニティ主導の建設が低炭素インフラにどのように貢献するかを質的に分析した。廃タイヤなどの地域素材を再利用し、参加型建設によって耐久性のある建物を実現し、熱的快適性の向上や雇用創出などの社会的便益が確認された。一方で、スケールアップには組織能力や専門的知識、制度的正当性が課題となる。

English

This qualitative case study of the Ulwazi Educare Centre in Cape Town examines how community-led construction using discarded tires and local materials can create climate-responsive infrastructure. It finds perceived benefits in thermal comfort, reduced mechanical heating/cooling, and social gains like skills development and employment, but notes constraints to scaling such as organizational capacity and institutional legitimacy.

日本のGX文脈において

日本の建設業界では、低炭素化が進む一方で、地域資源の活用やコミュニティ参加型の建設手法はあまり注目されていない。本論文は、日本の建設セクターにおける社会的包摂と脱炭素の統合の可能性を示唆し、SSBJやESG情報開示においても、サプライチェーン全体の社会的側面を考慮する重要性を再認識させる。

In the global GX context

This paper contributes to global debates on low-carbon construction by highlighting a socio-technical approach that integrates material reuse, passive design, and collective action, which is often overlooked in mainstream TCFD/ISSB frameworks. It offers insights for climate-resilient infrastructure in resource-constrained settings, complementing engineering-focused assessments.

👥 読者別の含意

🔬研究者:Provides a socio-technical framework for analyzing community-led low-carbon construction, useful for expanding research beyond techno-economic assessments.

🏢実務担当者:Offers practical insights into participatory construction methods that can reduce costs and enhance social value, though scalability requires professional support.

🏛政策担当者:Suggests that policies supporting community-led initiatives could foster low-carbon infrastructure in underserved areas, but need to address capacity and legitimacy gaps.

📄 Abstract（原文）

The construction sector accounts for a substantial share of global greenhouse gas emissions, yet many low-carbon building approaches remain inaccessible in resource-constrained settings because they depend on capital-intensive technologies and formal supply chains. This study examines how community-led construction can contribute to climate-responsive infrastructure through the integration of material reuse, passive environmental design and collective action. Using a qualitative case study of the Ulwazi Educare Centre in Delft, Cape Town, the research draws on 45 semi-structured interviews, field observations, project documents and photographs to explore the environmental, social and institutional dimensions of an alternative construction approach. The findings show that discarded tyres and other locally available materials were reconfigured into durable community infrastructure through participatory construction. Participants consistently associated the building with improved thermal comfort, reduced reliance on mechanical heating and cooling, opportunities for skills development, employment and collective ownership. The study interprets these findings through the lens of post-natural building, an analytical framework that explains how climate-responsive infrastructure can emerge from the interaction of material reuse, passive environmental design, and collective labour in resource-constrained contexts. The study also identifies important constraints to the wider adoption of community-led climate-responsive infrastructure. While participants perceived environmental and social benefits, scaling such approaches depends on organisational capacity, professional expertise and institutional legitimacy. The findings are based on qualitative evidence and do not quantify thermal performance or embodied carbon, highlighting the need for complementary engineering assessments. By integrating environmental, social and institutional dimensions, the study contributes a socio-technical perspective on low-carbon construction and expands debates on climate-responsive infrastructure in the Global South.
