Towards Topology-Oriented Digital Twins for Built Heritage Performance-based Management

Given the large stock of outdated buildings that support everyday activities, there is a pressing need to adapt them to the functional, environmental, and economic requirements of sustainable development in the built environment. Achieving this objective poses significant challenges and calls for a transition toward performance-based management of built heritage, underpinned by the digitalisation of the sector. This transition requires digital systems capable of acquiring, structuring, processing, sharing, and visualising building asset data to enable informed decision-making for asset managers. This research investigates how emerging digital technologies, such as Building Information Modelling and Building Performance Simulation, can be integrated into Digital Decision Support Systems (DDSS) to support strategic planning within a performance-oriented framework. The study first defines a conceptual framework grounded in the Digital Twin (DT) paradigm. It then develops methods and workflows for implementing DDSS solutions that support building performance management and are accessible to non-expert users through intuitive services.
