DIGITAL TWIN ARCHITECTURE

The life cycle of buildings, cities and the environment has become increasingly complex in recent years, regardless of the type of intervention, whether it is a new construction or a project on an existing building. In addition to the constraints and performance requirements associated with many kinds of use, there have been additional constraints and performance requests associated with: "augmented" functions of materials, components, and systems; renewed needs for well-being, safety, and energy efficiency; life cycle management, including predictive life cycle management; and inclusion, involvement, and entertainment of end users and stakeholders in general. Aspects such as those listed above get increasingly complex over time, depending on the type of object and intervention, like in the case of cultural heritage intervention, for example. In addition to the endemic need of the construction supply chain to implement information supports capable of fostering multiscale and integrated analyses by different professionals, recent needs have emerged for the processing, documentation and representation of data and information to: define and implement integrated digital collaborative environments; optimise the interoperability processes of codes and systems; implement automation protocols. Whether the digital twin is conceived as a "product", "object", "process" or "system" first raises the question of the relationship between the characteristics of the physical asset and the level of detail (scale) of the representation through the different methods, tools and procedures of digital modelling, representation and visualisation.
