An operational methodology for the technological recovery of building aggregates: towards an interoperability model.

The design methods for the building recovery of the historical heritage are characterized by complex cognitive processes based on multilevel readings. These studies are necessary to develop comparative analysis between the typological system, distribution/spatial system and technological system of the architectural organisms subject to building recovery. These studies deserve further in-depth knowledge when the recovery intervention to be carried out on the historic building is necessary following a calamitous event, such as an earthquake, where one of the prevalent activities is connected to the repair with improvement of the performance levels of the building. This contribution therefore illustrates a procedural path that allows us to overcome these difficulties in order to avoid that operational practice which is often summarized through the forced intrusion of resistant elements within the recovery project and which often finds inappropriate locations in the spatial and distribution system of the recovered historical building. In order to allow replicable decision-making processes, capable of guiding the design path, and with a view to also operating within digital information systems, a "multilevel operational domain" was defined capable of structuring an assisted process that allows carrying out, within an interdisciplinary and complementary context, the necessary validations of design solutions at multiple levels.
