The sustainability in the rehabilitation of minor historic centres. The case of seismic crater in Abruzzo Region: strategies and compatible methods.

The research links the issue of rehabilitation of the small historic centres, that characterized the Italian territory, to the environmental issue. The sustainable recovery is seen as opportunity to carry out a virtuous action in the territory, in the name of recognition of the importance of towns in the local organization, their environmental value and the re-use of an abandoned built heritage. The interest for these territories, particularly the inner area of the Abruzzo Region, hit by the earthquake of April 6, 2009, has offered the opportunity to carry out a research that aims to rediscover the present elements of environmental sustainability and to propose the integration of new forms of energy efficiency. The research proposes the development of an operative methodology that helps to overcome the gaps of the reconstruction process and those related to the promotion of energy efficiency in historical contexts. The main area of interest is not the built fabric, but the one complementary to it, characterized by open spaces and energy networks, of which main aspects are highlighted. The development of design scenarios allows us to involve different and complementary technological solutions in compliance with the case study, following a successful overcoming of a complex process of compatibility. The methodology aims at the elaboration of codes of practice to be a support tool to main actors related to the post-seismic reconstruction to create smart minor centres, through the application of a network of different interventions. It is being validated on a case study in the province of L'Aquila to verify the effectiveness of the presumed scenarios through the quantitative verification of the results and timing of application.
