La compatibilità delle tecnologie off-grid nella riqualificazione delle reti energetiche dei centri storici minori The compatibility of off-grid Technologies in the rehabilitation of energy network of minor historical centres

The research links the issue of recovery of the small Italian historic centres to the environmental issue, proposing the sustainable recovery as opportunity to carry out a virtuous action in the territory. The study of these territories, particularly the inner area of Abruzzo Region affected by the earthquake of April 6, 2009, offers the opportunity to carry out a research that aims to redevelop a heritage abandoned for year, now further compromised by the earthquake. An operational methodology aimed at energetic rehabilitation of the minor centres has been drawn up, which starts from an in-depth knowledge of the investigation area, identifying its peculiarity. Then we analyzed the intervention area and highlighted the applicable technologies through a careful “process of compatibility” (Zordan et al., 2002) with the context. In the present study there is an interest in the topic of energy networks, in their state of use and deterioration and possibility of renewable energy sources integration. In particular, we examine/analyze the offgrid technological systems potentiality and criticality, identifying the possibility of their application in the minor centres.
