“…Digitisation refers to transferring a process from an analogue form to a digital one (Gartner, 2023). Digitalisation can be defined as the outcome of applying digital technologies on a company's offerings (products or services), such as increased efficiency through automation (Gong & Ribiere, 2021). Digital transformation, on the other hand, is a broader concept that encompasses the integration of digital technologies into a business, as a whole new form, function, or structure, leading to fundamental changes in the business model that a company offers (Gong & Ribiere, 2021;Verhoef et al, 2021).…”

“…Digital transformation differs from digitalisation in terms of scope of improvement and end-results. Digitalisation revolves around incremental enhancements at the operational level, whereas digital transformation aims to implement a series of digitalisation projects that profoundly transform elements within a system at the strategic level (Gong & Ribiere, 2021). As it will be seen in the following sections, the building industry, particularly SHOs, are at an experimental stage in CE implementation and the use of digital technologies for circularity is mainly restricted to pilot projects.…”

This thesis explores the integration of Circular Economy (CE) principles of narrow, slow, close, and regenerate in the social housing practice through digital technologies. Beginning with the examination of the CE implementation in Dutch social housing organisations, the research extends its focus to the broader built environment, introducing the Circular Digital Built Environment Framework and identifying ten enabling technologies. Subsequent chapters explore realworld applications of these digital technologies in circular new built, renovation, maintenance, and demolition projects of forerunner social housing organisations. The thesis includes a comprehensive study of material passports, addressing challenges around data management and proposing a digitally-enabled framework. The thesis concludes with critical reflections on the findings and their implications and provides further recommendations for research and practical applications in advancing circularity in the building industry through digital technologies.

“…While some research are limited to the reuse of structural elements (Bertin, Ferraille, et al, 2019;Brütting et al, 2020), other investigations propose to mitigate the negative impact of linearity in the construction industry by using technologies such as BIM (Lebossé et al 2022;Bertin, Lebrun, et al 2019). Another approach is to find solutions to optimize the deconstruction of existing buildings (Gordon et al 2023). On another front, some aim to reuse materials using complex and not widely available digital technologies, such as 3D printing and robotic manufacturing (Mollica and Self 2016;Kunic et al 2021).…”

Whereas on a global scale, more than one billion people live in precarious housing situations, many construction materials are often sent to landfill sites or, worse, burned. However, these rejected materials represent a richness whose reallocation would lead to a significant economy of resources. Therefore, reusing materials from the construction industry could eventually be part of the solution. In this paper, we will present the results of a study carried out within the framework of a master's thesis project, which attempts to establish an architectural response to this issue. The proposed solution involves a constructive system that allows the assembly of temporary shelters using a wide range of reclaimed materials. This approach implies the use of digital tools to generate a form resulting from the analysis of locally salvaged materials. The algorithm developed in this project can generate multiple formal configurations optimized for the available resources. Any shape obtained in this manner will be composed of a low number (3-5) of unique edge lengths. This rationalization strategy also limits the unique triangle typologies in the structure to a manageable number. The different elements, whether planar or linear, are then joined using low-tech metal nodes that can be easily assembled and disassembled. Because the standardized edge lengths and triangle types are compatible, the proposed workflow unlocks mixed material reuse for complex reticular structures. The resulting flexibility allows for several variations or even a partial or complete reconfiguration of the initial shape, thus further supporting the implementation of the circular economy principles for the construction of complex architectural structures.

Digital Technology Use Cases for Deconstruction and Reverse Logistics

The transition towards a circular built environment challenges dismantling firms to revisit their practices. These firms traditionally demolish buildings with crushing force, essentially creating poorly recyclable waste. This practice leads to a loss of economic value and has several negative social and environmental consequences. Deconstruction, defined as construction in reverse, represents an alternative practice in which as many materials are recovered as possible. Deconstruction is particularly challenging because responsible firms need to process more information to organise various reverse logistics options efficiently. This chapter, therefore, reviews reverse supply chain practices in construction and illustrates how digital technologies could support dismantling firms and their partners during essential deconstruction activities. Through evidence-based insights and examples from practice, the chapter presents a state-of-the-art overview of digital deconstruction technology use cases for identifying, harvesting, and distributing reusable building elements. It shows that digital technologies have been developed for separate deconstruction activities but are rarely used in an integrated manner. Further integration through aligning the digital technologies with practitioners’ information needs will, accordingly, unlock new opportunities for closed-loop material flows.
