DAL PIANO PARTICOLAREGGIATO AL PROGETTO DI IDENTIFICAZIONE DEI CENTRI STORICI. UN APPROCCIO ANALITICO AI COSTI PARAMETRICI NELLA PROSPETTIVA DI UN MODELLO DI PROGRAMMAZIONE STRATEGICA

Abstract

In the perspective of the participatory programming, nowadays main-stream in all spheres of urban planning, the analysis of the parametric costs has been affirmed as an important design tool; it’s requested, at all levels, to increase the transparency and flexibility of the plan, and play an important role in the knowledge process for decision makers as well as for users and stakeholders. The experimental context of this study is the old town of Ragusa Superiore, a large urban fabric consisting of 8600 architectural units, quite homogeneous from the constructive point of view, but not from the typological and morphological ones. The analysis supports a strategic planning process based on the design of several option of intervention strategies (more conservative or transformative), envisaging a certain degree of flexibility in sorting the involved Architectural Units between the different Intervention Categories; in this role, the proposed pattern allows us to associate in real time the parametric cost to each of the different Intervention Categories supposed in each simulation. The parametric cost analysis is based on the typing of the analysed fabric, consisting of 1788 architectural units and provides a wide range of unit costs to indicate feasibility and convenience of the real estate investments in order to define a possible incentive program aimed at internalizing the urban externalities resulting from the more general process of enhancement of the entire old town.
