An Evaluation System to Optimize the Management of Interventions in the Historic Center of Florence World Heritage Site: From Building Preservation to Block Refurbishment

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 heritage. The proposed methodology is based on specific methods of analysis of degradation and parameters for the optimization of construction costs. The methodology can be considered an additional part of the Management Plan of the site of the Historic Center of Florence (adopted for the first time in 2016 and now updated with the inclusion of a buffer zone) 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 harmony 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 provides for a reinterpretation of the existing building heritage. From the monitoring of individual buildings, aimed at their preservation, we will move to study the relationships that promote the creation of joint construction sites, thus optimizing costs.
