Decision Support System for the Management of Interventions on Buildings in the Historic Centre of Florence: From Conservation to Regeneration

The goal of this paper is to present a methodology for setting priorities among interventions in the old city center of Florence, going from the conservation to the regeneration of its herit-age. The possibility to re-use a building with new characterizations depends on binding and administrative issues while the optimization of resources depends on the planning and organ-ization of the construction sites. The proposed methodology falls within the so called "mixed methods", as it integrates within a multi-criteria model, specific methods of analysis of deg-radation and parameters for the optimization of construction costs. This research proposes a model that interfaces and integrates projects already running in the area already included in the. This, data will be included in the Geographic Information System for the integrated analysis, monitoring, and management of the transformations of the building heritage in the historic center of Florence that is under development. The methodology can be considered an additional part of the Management Plan of the site of the Historic Center of Florence that "represents an important tool for the conservation and enhancement of the Heritage, and is also a source of address for the choices that the Administration is called to adopt regarding the use of the city and its spaces". The application of the method, in addition to being in har-mony with some of the action projects of the second macro-area of the new management plan, also has points of contact with the provisions of the Municipal Operational Plan that at point 4.3 provides for a reinterpretation of the existing building heritage. From the monitoring of individual buildings, aimed at their preservation, we will move on to study the relationships that promote the creation of joint construction sites, thus optimizing costs. Hence the meth-odology selects areas suitable for regeneration, whose different transformation alternatives are evaluated (HIA) and hierarchized (MCDA).
