Il paradigma del gemello digitale per la gestione prestazionale del patrimonio costruito. The Digital Twin Paradigm for the Performance-based Management of Built Heritage

Building management has become a significant issue in recent years. Many outdated buildings built in the 20th century need daily upgrades and improvements related to safety, operation, and maintenance, involving high costs and impacts. Nevertheless, building management practices are only sometimes equipped to effectively address the complexity of the contemporary requirement framework, often facing challenges such as lack of expertise and coordination, financial limitations, poor information, and scarce data visualisation tools. The digital transition of the Architecture, Engineering, Construction and Operation (AECO) sector presents an opportunity to solve these issues. In particular, the Digital Twin (DT) paradigm has been emerging in recent years since, integrating different technologies, it can improve building operations and support asset managers in decision-making by giving reliable estimations and predictions about building performance. This paper illustrates a new framework for including the performance dimension in digital built asset management, focusing on the operation phase of existing buildings. Based on a service-oriented DT model, this framework guides the development of a DT platform prototype combining Building Information Modeling (BIM) and Building Performance Simulation (BPS) data collected from a case study belonging to the University of Bologna, Italy. Information is structured according to a specific methodological approach to drive future sensor data integration in the platform.
