Criticity Mapping and Integration Quantity Evaluation of Solar Installations in Mediterranean Heritage Territories

The study aims at evaluating the applicability of the LESO-Quality-Sensitivity-Visibility (QSV) method for the assessment of active solar installations on Mediterranean architectural heritage. To this purpose, 10 significative case studies with the integration of photovoltaic and solar thermal system have been evaluated using this method. This assessment is compared with the results of expert enquires realized on the same case studies by the Heritage Authorities, to define potentialities, limits, and possible modifications. Finally, the integration of the two methodologies with international policies allows the definition of an articulated set of formal characteristics that solar systems in heritage contexts should have.
