The massive incentives provided by the Italian government for sustainable building, in view of the post-pandemic economic recovery, risk being reduced to mere support for the real estate sector, which turns the financial transfer from the public into an increase in asset value for the private sector. Such an incentive system could contradict the original function of the city, which is to be the privileged place for social communication and the creation of the identity of settled communities. A process of property development that disregards the distribution of income favors the most valuable property, thus increasing the socioeconomic distance between centrality and marginality. The latter is a condition that often characterizes the parts of the hist...

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 t...

Il progetto di identificazione e l'approccio generativo Il tema della riqualificazione dei centri storici sta oggi at-traversando un significativo cambio di prospettiva a causa di due diversi e convergenti tipi di fenomeni. Il primo è il processo di progressiva riduzione dell'in-fluenza della mano pubblica quanto a intenzionalità pro-gettuale ed erogazioni finanziarie, che lascia maggiore spazio alla partecipazione del soggetto privato, special-mente all'interno dei contesti urbani più estesi e meno qualificati in senso architettonico e paesaggistico; di con-seguenza, si assiste alla modificazione dell'approccio ge-nerale al piano, sempre meno attento ai mezzi e più ai fini [1, 2], in molti casi ridotti e filtrati dalle stringenti e ormai strutturali difficoltà economiche. Questo aspetto desta alcune preoccupazioni legate al fatto che, nel caso dei centri storici e, più in generale, dei beni culturali, il reticolo assiologico che costituisce le mo-ti...

Introduzione Il destino dei centri storici caratterizzati da qualità archi-tettonico-urbanistica diffusa, costituisce l'epitome di un processo che più in generale-e guardando a questioni ben più ampie della "sorte di case e piazze", della acces-sibilità, della conservazione dei monumenti-interessa il patrimonio edilizio-urbano in quanto categoria economica ad elevata capitalizzazione di valori e dis-valori. Un patri-monio oggi sempre più soggetto a una strutturale con-vergenza tra costi e prezzi, quindi alla riduzione di quei margini di profitto attesi, che avevano motivato gli inve-stimenti immobiliari nelle fasi espansive e spinto la pro-duzione di nuova edilizia ben oltre i limiti "fisiologici" della domanda di case, conducendola in pieno territorio "pa-tologico", quello della domanda di capitali che, preva-lendo, ne ha modificato alla radice il senso e le funzioni. Le diverse dinamiche dei prezzi-tra centri e periferie, tra contesti storici e...

It proposes a global economic-evaluative strategic planning pattern supporting decision-making in developing a specific energy-environmental equalization program. Starting from the huge database of the GIS describing the Architectural Units forming the old town’s urban fabric, the pattern features each of them with several architectural and energy attributes, so that each of them can be sorted among the different Categories of Intervention, ranging from the conservative to the transformative ones. Furthermore, the energy characteristics of all the AUs of the sample have been modelled in order to calculate the energy performance to be improved. The combination of architectural and energy characteristics provides the profile of each AU according to which the pattern associates to it the appropriate CI and calculates the related cost and real estate market price surplus to be used for the equalization. By releasing the constraint according to which an AU is sorted to a specific CI, the pattern is able to design several global strategies that can be ranked by performing a MAVT model.

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 axiolo...

In the climate of the centre-northern part of Italy, and in the context of the recent concentration of a high number of earthquakes in that area, seismic vulnerability can become the determinant cause of the final abandonment of a small town. In some Italian regions, as well as in Emilia Romagna, municipalities are implementing seismic vulnerability reduction policies based on the Emergency Limit Condition, which has become a basic point of reference for ordinary land planning. This study proposes an approach to seismic vulnerability reduction based on valuation planning for implementation within the general planning framework of the Faentina Union, a group of five small towns located in the southwestern part of the Province of Ravenna, Italy. This approach consists of three main stages: knowledge—the typological, constructive, and technological descriptions of the buildings, ...

In the climate and in the context of an increasing seismic risk in the center-northern part of Italy, seismic vulnerability can become the determinant cause of the final abandonment of a small town. In some Italian regions, as well as Emilia Romagna, municipalities are implementing seismic vulnerability reduction policies based on the Emergency Limit Condition that has become a basic reference for ordinary land planning. This study proposes a valuation planning approach to the seismic vulnerability reduction carried out within the general planning framework concerning the Faentina Union, a group of five small towns located in the south-western part of the Province of Ravenna, Italy. The approach consists of three main stages: knowledge – the typological, constructive and technological description of the buildings specifically concerning their vulnerability degree; interpretation – t...

Its differently valued areas need to be comprised in a whole valorisation strategy, connecting the decision making process with functional and symbolic values. In such a multi-layered urban sub-system, the architectural unit can play the role of one of the main information/value units which the valuation/decision making pattern starts from. The pattern works as an impact assessment tool, that generates a great number of intervention strategies in order to maximize different and conflicting objectives, and provides for each of them an axiological profile aimed at defining a trade-off scheme between them. Some GIS tools and a WebGIS interface allow the real-time control of the different scenarios envisaged in the decision making process.

Among the planning tools for reducing the vulnerability of urban fabrics, the Emergency Limit Condition (ELC) defines the fields which require widespread strengthening interventions in the buildings involved in resilient town units. The extent and intensity of such interventions can be graded so as to find an optimal ELC measure, taking the needs of the urban and human capital into account. In case of the old town centre of Ragusa, a model for analysing the seismic vulnerability of the built-up areas has been integrated with a model for a cost-revenue estimation in order to identify the conditions of the ELC dimensioning and to develop the relevant incentive system.
