A BIM-Based Digital Twin for Smart Building Operations: The SMARTeeSTORY Demonstration

Within the framework of the European SMARTeeSTORY project, an IFC-based Digital Building Twin service has been developed for the management and operation of historic non-residential buildings. The solution is connected to a Digital Building Logbook, enabling facility managers to manage building documentation and update the BIM models used to generate and maintain the Digital Twin. The platform integrates 2D and 3D visualisation capabilities with monitoring, control, and prediction services developed within SMARTeeSTORY. Through this closed-loop approach, the system enables both real-time data visualisation and interaction with building systems, supporting more efficient building operation and decision-making processes. This presentation introduces the solution, which is currently being validated in three real-life demonstration sites: Riga City Hall in Latvia, the Faculty of Architecture and the Built Environment at TU Delft in the Netherlands, and the Chancillería Palace in Granada, Spain, all of them historic non-residential buildings. Presented at the European Construction Technology Platform (ECTP) Conference 2026 in Brussels, as part of the session Application of Digital “Cutting Edge” Solutions to Real Use Cases.
