In Libya, adopting these technologies could address housing shortages and enhance construction efficiency. This study applies the Unified Theory of Acceptance and Use of Technology (UTAUT2) model and the Task-Technology Fit (TTF) framework to investigate factors influencing the adoption of prefabricated building technologies. Using Structural Equation Modelling (SEM) to analyse survey data, key variables such as performance expectancy, effort expectancy, social influence, facilitating conditions, affordability, and government support were examined. The findings reveal that performance and effort expectancy are the strongest drivers, with adoption more likely when users perceive efficiency and ease of use. Social influence, facilitating conditions (e.g., resources, infrastructure, technical support), and logistic factors (affordability and government support) also significantly impact adoption. Cultural alignment with local practices further supports implementation success. The study recommends raising awareness, enhancing technical infrastructure, and establishing robust government incentives and policies to promote adoption. These strategies are essential for addressing Libya's housing challenges, advancing construction efficiency, and fostering sustainability in the industry.

Introduction The construction industry significantly contributes to global environmental issues, generating over 40% of human-produced carbon dioxide (CO 2 ) emissions [1]. Prefabricated buildings offer a sustainable alternative by being manufactured in controlled factory environments and later assembled on-site, enhancing efficiency and reducing environmental impact. This method employs modular components and mechanisation, facilitating material recycling and reuse, improving efficiency, cost savings, reducing waste, lowering pollution, resource conservation, decreasing labour demands, and enhancing safety standards [2]. A complex interplay of socio-cultural values, economic instability, and environmental constraints shapes Libya's housing landscape. Rapid urbanisation, demographic shifts, and long-standing political turmoil have strained the country's housing infrastructure. Following the 2011 civil conflict, the destruction of residential neighbourhoods and the collapse of public service systems have left large segments of the population living in inadequate or informal dwellings. Housing shortages are particularly severe in
