Dall’HBIM al Digital Twin. La ricezione dei dati dinamici per la programmazione degli interventi conservativi

Digital Twins – as well as HBIM models on which they are based – are among those technological tools that today can facilitate, if well directed, the implementation of methodological assumptions that were already fully formulated in the Venice Charter: the importance of documenting the building and the interventions carried out as well as the subsequent publication of the information collected; the systematic execution of maintenance activities (today we would say conservation); the use of all techniques contributing to the conservation of architectural heritage. Sixty years later, the changed conditions, including technological advancement, pose different challenges to those in-volved in conservation. The aim of the contribution is, therefore, to provide a definition of the interdisciplinary con-cept of Digital Twin as a tool to support planned conservation practise, highlighting its potentialities and risks, also through the critical analysis of the main results obtained so far in the field of conservation and monitoring of histori-cal structures. The first outcomes of the application of this approach to the case study of Palazzo Pallavicino in Par-ma – particularly interesting because of the large amount of data available – will then be discussed.
