Bipv in the recovery of minor historical centers. the project of integrabilitY between standard and customized technology

The building integration of photovoltaics (BIPV) applied to the recovery project, has shown, in various forms and with different degrees of success, interesting possibilities for architectural and technological upgrading of the pre-existence, including a high acceptability in sensitive contexts. The basic built of historic "minor" settlements, typical of the Italian building heritage (consisting of a network of small centres with high historical, landscape and environmental value) poses new methodological challenges to the conservation project related to the control of energetic of and eco-sustainability aspects. In the revitalization of these places, typically characterized by a pre-modern material culture that forms the main testimonial value, the implementation of bioclimatic strategies and systems for using renewable energies, requires an accurate process to verify the integrability, variable in each case and to articulate at different scales: from building components to the village dimension (roads, open spaces, urban voids ...). In a contemporary context increasingly oriented towards the "mass customization" of the building industry, the study of forms of integration may take advantage from an innovative "craft dimension" of technology which, more and more adaptable to the design paradigm of the "micro-intervention" and "controlled transformation" (thanks to the control of technological and figural details at scale of the component or base material), shows new scenarios of "compatibility" compared to the degree of "transformability" of these places. The proposed study is aimed to narrow design BIPV paradigms for the recovery of these historical contexts, in particular by defining strategic criteria related to linguistic-architectural and technological-constructive aspects of solar systems (including case-studies in specific application contexts). This research would, once perfected and shared, creating a critical and operative tools (guidelines, case studies ...) really applicable to common scale, e.g. in today's post-earthquake reconstruction of L'Aquila, for control adequate BIPV interventions within a specific eco-friendly method of recovery.
