Context and Overview
This resource is a comprehensive review of Circular Industrialised Construction (CIC) for sustainable and affordable housing, published by Sustainable Cities and Society. The authors, Annette Davis, Núria Martí Audí, and Daniel M. Hall, analyze the integration of circular economy principles within the housing sector to address pressing environmental and social challenges.
Key Findings
The review examines 65 publications across various continents, revealing that Circular Industrialised Housing (CIH) can significantly contribute to sustainable living by enabling the disassembly and reuse of building components. It identifies six key factors influencing this approach: cultural, governance, financial, site and logistics, construction system, and building information. These factors collectively shape 15 recurring themes and 36 sub-themes relevant to the housing lifecycle.
Proposed Framework
A novel process-driven framework is proposed, encompassing four core stages: (re)planning, (re)designing, (re)manufacturing, and (dis)assembly. This framework aims to capture the entire lifecycle of housing, facilitating a transition from linear to circular practices. The findings highlight a disproportionate emphasis on (re)designing (55%) compared to (re)manufacturing (20%), (re)planning (13%), and (dis)assembly (12%), indicating a need for a more balanced focus across all stages.
Housing Challenges
Providing sustainable and affordable housing is essential as urban populations are expected to reach 9.8 billion by 2050, with 70% living in cities. The construction industry currently contributes significantly to CO2 emissions and consumes approximately half of the world's natural resources. The review emphasizes that the transition to a Circular Economy (CE) can mitigate these impacts while enhancing housing affordability.
Innovations in Construction
The paper discusses two important concepts: Industrialised Construction (IC) and Design for Disassembly (DfD). IC focuses on the systematic production of buildings, while DfD emphasizes the design of buildings for future disassembly. These approaches can help reduce material waste and improve resource efficiency, which are critical for sustainable housing.
Literature Gaps
Despite the promising potential of CIH, the review identifies significant literature gaps, particularly concerning socio-economic dimensions and governance related to disassembly. The need for empirical studies and practical applications in social and affordable housing is highlighted, as existing literature predominantly focuses on the private market.
Future Research Directions
The authors encourage future research to refine the proposed framework through case studies that integrate IC, DfD, and reuse principles. This interdisciplinary approach could enhance the understanding and implementation of circular housing solutions, ultimately contributing to more equitable and sustainable urban environments.
Conclusion
Overall, this review offers a holistic perspective on Circular Industrialised Housing, providing a structured lens to inform research, policy design, and industry practices. It serves as a roadmap for advancing resource-efficient, regenerative, and equitable housing outcomes across Europe and beyond.
