PROGRAMMAZIONE STRATEGICA E VALUTAZIONE GENERATIVA NELLA RIQUALIFICAZIONE DEI TESSUTI URBANI STORICI

Vittoria Ventura, Salvatore Giuffrida

Abstract


The old town of Ragusa is undertaking a process of progressive urban enhancement in some different directions. Its differently valued parts should be covered by a general valorization strategy connecting the decision making process with functional and symbolic values that need to be adequately analyzed and represented. In such a multi-layered urban sub-system, the Architectural Unit can play the role of main information/value unit from which the valuation/decision making pattern starts. The proposed pattern includes, connects and systematizes the analysis, valuation and planning stages by coordinating quantitative appraisals and qualitative multi- criteria assessments based on a MAVT pattern. In particular, the planning stage is aimed at associating the fair Intervention Category to each Architectural Unit by generating a great number of overall intervention strategies in order to maximize different and conflicting objectives. Thus, the strategies are compared basing on their axiological profile, to lay down a trade-off scheme between them. The pattern endorses a semiotic interpretation of the urban fabric, sorting the single Architectural Units by signs, symbols and icons.
