    CIRCULAR ECONOMY PRINCIPLES IN THE BUILT ENVIRONMENT: A SYSTEMATIC LITERATURE REVIEW
    (2025-06-30) Soliu, Idris; Migliaccio, Giovanni C.
    The impact of the consumerism economy model on environmental degradation, waste generation, and resource depletion has heightened the attention of industry practitioners, academic scholars, and policymakers toward the adoption of the Circular Economy in the last few decades. Consequently, being a resource-intensive and waste-generating industry, the built environment has embraced the paradigm shift from a take-make-use-dispose approach to emerging economy models to withstand future shocks. While the literature on circular economy concepts, frameworks, and business models is rapidly growing, the empirical evidence regarding the practical implementation of circularity principles is scarce within the built environment. However, transitioning to a circular built environment is unrealizable unless principles of circularity are fully integrated into the building lifecycle. Consequently, the present study investigates the research trajectory of Circular Economy Principles (CEP) within the built environment through a systematic literature review. The study employed the Preferred Reporting Items for Systematic Review and Meta-Analysis framework to conduct a literature search on two prominent databases, Web of Science and Google Scholar, and thematic analysis was conducted to evaluate the research trend and identify the knowledge gap. The review found that significant attention was given to certain circularity principles, while others received less focus over the past decade. Additionally, the study uncovered areas where further exploration is needed because of the existing knowledge gaps identified in the current study. This study sheds light on the evolving landscape of the circular economy within the built environment, underscores the progress made, and concludes with the areas that require further exploration to achieve a circular built environment.

    Charging Forward: Evaluating Public-Private Partnerships for Electric Bus Base Conversion to Support a Zero-Emission Fleet
    (2023-11-27) Lee, Hyun Woo “Chris”; Osburn, Laura; Treece, Barton G., III
    As transit agencies shift to a zero-emissions fleet, bus bases that function as the heart of operations will also need to convert to support a growing demand for battery-electric buses (BEB). Although there are traditional procurement methods available for transformative redevelopment of these facilities, there is opportunity to leverage a public-private partnership (P3) that can be an innovative and cost-effective project delivery method when applied appropriately and potentially result in several positive outcomes. These may include shifting finance, design, construction, operation, and maintenance risk to a private entity; augmenting and training the workforce needed for electric vehicle operations and maintenance; offering effective ownership and efficient servicing of charging equipment; spreading costs over a longer time period; and locking in energy costs.

    MESSY TALK IN VIRTUAL TEAMS Achieving Knowledge Synthesis through Shared Visualizations
    (2014-07) Dossick, Carrie Sturts; Anderson, Anne; Azari, Rahman; Iorio, Josh; Neff, Gina; Taylor, John E.
    Engineering teams collaborating in virtual environments face many technical, social and cultural challenges. In this paper we focus on distributed teams making joint unanticipated discoveries in virtual environments. We operationalize Dossick and Neff’s definition of “Messy Talk” as a process in which teams mutually discover issues, critically engage in clarifying and finding solutions to the discovered issues, exchange their knowledge, and resolve the issue. Can globally distributed teams use “Messy Talk” via virtual communication technology? We analyzed the interactions of four distributed student teams collaborating on a complex design and planning project using building information models (BIM) and the CyberGRID, a virtual world specifically developed for collaborative work. Their interactions exhibited all four elements of Messy Talk, even though resolution was the least common. Virtual worlds support real time joint problem solving by 1) providing affordances for talk mediated by shared visualizations, 2) supporting team perceptions of building information models that are mutable and 3) allowing transformations of those models while people were together in real time. Our findings suggest that distributed team collaboration requires technologies that support Messy Talk--and iterative trial-and-error--for complex multidimensional problems.
