IL DIGITAL HERITAGE PER LA RIQUALIFICAZIONE SOSTENIBILE DEL COSTRUITO STORICO

The paper explores the application of Industry Foundation Classes (IFC) in the energy retrofit of historic buildings. The methodology integrates information on building components into the IFC framework. The approach proposes additional parameters to enable a comprehensive assessment of heritage value, visual appearance and physical materiality of building elements alongside geometric and physical information. The preliminary evaluation provides insights into the feasibility of energy retrofit interventions and their potential impact on building energy performance, considering preservation constraints. The application on Villa Venier Contarini, whose energy assessment indicates significant heat losses, suggests the need for interventions. Results show how IFC can provide a solid foundation for decision-making, which enables the study of refurbishment options and respects the building's significance by focusing interventions on specific portions. A comprehensive view of the retrofit process emerges from this approach. Its structure promotes cross-disciplinary collaboration and maintains interoperability standards. This research contributes to the ongoing discussion on sustainable preservation of historic buildings through the development of a method for preliminary assessment of retrofit opportunities. It highlights the potential for broader application to entire building stocks, enabling a priori estimation of retrofit opportunities.
