Digitalisation and ecological transition through digital twins. An added value for society.

Digitalisation and ecological transition are two great areas that in recent years are transforming the way of life of our society. The questions are different: how can digitalisation foster the ecological transition? How can the current heritage constitute an added value for the challenges of the future? The study of digital twins determines a conscious situation of the reality we live in, encouraging methods of intervention. The contribution focuses on the analysis of digital twins, differentiating them into five levels with a progressive development of automations and artificial intelligence, up to make the model independent from a decision-making point of view, that is, able to evaluate and decide independently on the basis of the data collection. The digital twin, therefore, has the task of entering into the essence of the territory and the buildings, analyzing how man relates to it, with the aim of presenting itself as an added value to planning and sustainable management. The goal is to clarify the overview of digital twins at present and to determine how they can become a tool to improve the quality of life of our societies, generating social and economic value.
