Bibliometric Analysis of the Intersection of Circular Economy, Prefabrication, and Modularity in the Building Industry

This study aims to examine the latest literature at the intersection of prefabrication, modularity, and the circular economy (CE) through a bibliometric analysis. This systematic review follows five key steps: design and conceptualization, bibliometric data collection via the Scopus database, assessment of the collected data, data visualization, and discussion of the findings. The results are categorized into five main themes: prefabrication and modularity, CE in the construction sector, energy and environmental life cycle assessments, life cycle costing (LCC), and digitalization. The findings reveal that prefabricated and modular systems align with CE principles, supported by strategies such as disassembly and deconstruction design, as well as recycling and reuse. However, the direct connection between prefabrication/modularity and CE remains relatively weak, with environmental life cycle assessment (LCA) and building information modelling (BIM) emerging as the two primary methodologies bridging these concepts. To further advance the integration of prefabrication and modularity in CE, there is a need for the development of reliable guidelines and regulations that establish these practices as core requirements within the construction industry.
