Digital Twin solutions to historical building stock maintenance cycles

The purpose of this work is to provide a framework for the vulnerability of traditional historical buildings. Buildings that are not constrained and do not have a design obligation for minor energy retrofit interventions. The digitization of the construction sector can help to design interventions with Digital Twin methodologies that can be integrated into a single document that collects them as the Digital Building Logbook. We propose a definition of an innovative workflow that defines integrations and technological innovations in the historical building stock. In this work are presented operational proposals to ensure and increase the protection and conservation of the Italian historical building stock, trying to strengthen the activities of designers and companies for the reduction of seismic vulnerability in case of maintenance or energy retrofit.
