BIPV in The Refurbishment of Minor Historical Centres: The Project of Integrability between Standard and Customized Technology

"One of the main challenges for sustainability in the next years will be the retrofit of existing heritage. Even the most ancient settlements, to avoid the definitive neglect, will have to be opened towards a 'contemporary ' logie of refurbishment including a 'right' technological contribution as well as an environmentally aware reflection,aimed to establish a deeper di• alog with materiai,water and energetic-climatic resources. n ltalian territories hit by earth• quake, this challenge is already today a potential for the life return: BIPV (Building ntegrateci Photovoltaic), or ingenerai PV integration, is one of the possibleways that needs to be faced without ideologica! preclusions within an eco-sustainable refurbishment approach .The re­ search path is aimed to research possible criteria, compatible tools and examples for the technological transfer of solar systems in the refurbishment processes of minor historical centres. The photovoltaic 'integration project ' in sensitive areas, differently from ordinary contexts, needs a specific methodological approach linked to the topics of 'controlled trans­ formation' and 'compati bility of integration'. The typical design complexity inthese contexts has so far paid a widespread prohibition with few realized examples, although the research has already showed a possible 'acceptance' even in areas with high values. The study pre­ sented deepens the topic of 'photovoltaic integrability', as an opportunity for a 'possible' and 'duty' innovative refurbishment of the historical minor built. The research specifically identifies, for different scales of intervention, possible integration ways of solar systems in the process of reconstruction in !.'A. quila, starting from some methodological criteria previ­ ously defined for the architectural language contrai and for the technological requirements of PV components. The outcome of this research could be the introductìon of criteria for PV integration in the reconstruction process. This research, once compieteci and shared (e.g. throughguide-lines, tools, quantitative evaluations, etc.), could be a basic instrument for lo­ cai authorities and operators, to guide the reconstruction policy of the next years on a path of energetic innovation, at the same time eco-friendly,technologically advanced and in full respect of historical,environmental and landscape values of these places.. .
