As digital technologies mature, digital twins are emerging as powerful tools that extend far beyond visualisation in the built environment. By creating dynamic, data-driven replicas of physical assets, digital twins enable continuous monitoring, simulation and optimisation across the entire lifecycle of buildings and infrastructure. This panel brings together perspectives from technology, engineering, asset management and design to reflect on how digital twins are being applied in practice to enhance performance, improve decision-making and support sustainability goals. It will also consider the challenges surrounding data integration, scalability, interoperability and long-term value creation, highlighting how digital twins are redefining the way we understand, manage and future-proof the built environment.
