La riqualificazione sostenibile delle reti energetiche e territoriali nel patrimonio edilizio storico minore. The sustainable renovation of energy and territorial networks in the minor historical building heritage.

In the context of EU policies for sustainable development, including the Europe 2020 Strategy and the "SDGs 2030", the common goal is to operate on existing urban areas through rehabilitation strategies and projects based on a smart, sustainable and inclusive approach. Nevertheless, the state-of-the-art highlights strong shortcomings in the definition of strategies and methods for the identification of compatible interventions in consolidated contexts, such as, for instance, the minor historical centres, which characterize the Italian territory. Among the less investigated aspects in these areas, there is the one that concerns supply, distribution and subsequent energy and services management. Between them, it also could be possible to mention the one regarding how the technological plant system elements maybe integrated into an urban fabric that was not originally born to welcome them. Therefore, the paper is aimed at illustrating the research result, that is focused on the dissemination methods of technological systems in order to improve, replace and integrate technological and energy networks. A particular attention is paid to the opportunity of exploiting renewable energy sources. On a territorial scale, the aim is also to suggest network management models that are sustainable and replicable in contexts of partial settlement discomfort, that are able to use the efficiency and optimization of the services to promote the inversion of the demographic trend and to increase the appeal of the smaller historical centres. The validation of the proposed methodology was carried out through the design experimentation on Raiano, a minor village in the Province of L'Aquila, with the aim of being replicated in other villages and becoming a useful operational tool for administrations and local authorities.
