Digital twins and Building Information Modeling (BIM) are transformative technologies reshaping the smart management of public buildings post-occupancy. A virtual representation of a physical asset that utilizes real-time data to monitor performance, while BIM involves the generation and management of digital models throughout a building’s lifecycle. The integration of these technologies allows for enhanced operational efficiency, predictive maintenance, and improved decision-making, ultimately driving sustainability initiatives and tenant satisfaction in public infrastructure. T he emergence of digital twins, rooted in advancements such as the Internet of Things (IoT), Artificial Intelligence (AI), and big data analytics, marks a significant evolution in building management. This shift, which began in the early 2000s, enables the continuous updating of digital models based on live data, bridging the gap between physical structures and their digital counterparts. Research initiatives have highlighted the potential of these technologies to create predictive models that enhance operational strategies and support comprehensive building performance analysis. The synergy between digital twins and BIM offers significant benefits for the management of public buildings, paving the way for smarter, more efficient environments. However, overcoming the existing challenges is crucial for realizing the full potential of these innovations in enhancing facility management, energy efficiency, and occupant safety.
