In response to the construction sector’s contribution to the climate crisis and exacerbation of social inequalities, we explore sustainable alternatives in building construction, informed by the illustrative case study of the Polycare construction system. First, through a Life-Cycle Assessment (LCA) method, we show that the ecological footprint of circularity-oriented buildings based on polymer concrete is significantly lower than that of conventional cement concrete buildings. Despite the drawbacks of polymer concrete, its high-performance properties and the possibility to integrate secondary materials in its recipe can result in a reduced carbon footprint. When coupled with design-embedded modularity that facilitates circular processes (e.g., the disassembly and reuse of building components), buildings similar to those in the case study demonstrate potential for transitioning towards comprehensive sustainable building practices. Further, we discuss how this sustainability potential could be enhanced, drawing from interviews with Polycare’s stakeholders and key literature findings. In this direction, we provide a set of proposals anchored in the argument that threefold “circularity, localisation, and openness” is vital for sustainable and affordable alternatives, with openness being a crucial element for fostering innovation, adaptability, and scalability in building processes.

In this article, we explore the sustainability potential of an alternative commons-based mode of production called cosmolocalism. Cosmolocal production combines global knowledge production with local physical production. Such a production mode has been applied across the globe for locally manufacturing small wind turbines (SWTs) for rural electrification. We assess the sustainability of such cosmolocal SWTs in a case study of electrifying a rural community in Ethiopia. In this context, the life cycles of five SWT alternatives have been compared, ranging from conventional industrially produced turbines to open-source locally manufactured and maintained ones. Our case study indicates that the local manufacturing and maintenance of SWTs offer significant advantages and may redeem small wind turbines as a sustainable component for rural electrification. Specifically, the fully cosmolocal alternative (A1) performs better than any other alternative in technical, environmental, and social criteria, while it is close to the best-performing alternative with regard to economic objectives. For this solution to be implemented, the institutional burden cannot be neglected, but can rather be considered a sine qua non condition for locally manufactured and maintained SWTs. A set of generic institutional interventions to create favourable conditions for cosmolocal production is proposed, which needs to be elaborated in a context-specific manner. Full article

The starting point of this article is the critique on socioeconomic and environmental implications of conventional construction practices around sustainability. The focus is on exploring the sustainability dynamics of the emerging “Design Global, Manufacture Local” (DGML) configuration with emphasis on building construction. Combined with the concept of conviviality which we identify in aspects of vernacular architecture we explore how it can foster meaningful sustainability practices in the construction sector. We introduce a framework of “open construction systems”, an expression of DGML in building construction, as a way to foster the conjunctive use of the digital commons and local manufacturing technologies for the construction of buildings through three interlocked elements—modularity, sharing and adaptability. We suggest that the “open construction systems” framework may point towards more sustainability in building construction. Full article

Assessing the Openness and Conviviality of Open Source Technology: The Case of the WikiHouse

The housing crisis has received growing interest from academia, industry, and policymakers. Open construction systems have emerged as a promising solution to achieve long-term social, economic, and environmental sustainability. In this paper, extensive fieldwork was conducted to investigate a case of an open construction system, namely, the WikiHouse Den Bosch. The research framework builds on a combined view of two main concepts: “conviviality” and “openness”. The aim is to provide an in-depth understanding of the relationship between these two aspects and the literature regarding “Design Global Manufacture Local”. The analysis showed that conviviality and openness are complex and context-specific factors. The paper concludes by outlining the need for an “institutionalized conviviality” to open up new pathways for future practice to address sustainability issues. Full article
