Technological, Axiological and Praxeological Coordination in the Energy-Environmental Equalization of the Strategic Old Town Renovation Programs

This contribution deals with the energy-environmental interventions to be encouraged and subsidized over the implementation of the Detailed Renovation Program of Ragusa Superiore, Italy. It proposes a global economic-evaluative strategic planning pattern supporting decision-making in developing a specific energy-environmental equalization program. Starting from the huge database of the GIS describing the Architectural Units forming the old town’s urban fabric, the pattern features each of them with several architectural and energy attributes, so that each of them can be sorted among the different Categories of Intervention, ranging from the conservative to the transformative ones. Furthermore, the energy characteristics of all the AUs of the sample have been modelled in order to calculate the energy performance to be improved. The combination of architectural and energy characteristics provides the profile of each AU according to which the pattern associates to it the appropriate CI and calculates the related cost and real estate market price surplus to be used for the equalization. By releasing the constraint according to which an AU is sorted to a specific CI, the pattern is able to design several global strategies that can be ranked by performing a MAVT model.
