Integrated programming for the enhancement of minor historical centres. The SOSTEC model for the verification of the economic feasibility for the enhancement of unused public buildings

In the context of integrated projects aimed at enhancing historical centres, one of the most important aspects is the re-use of unused public buildings. The effectiveness of the decision-making process that leads to the identification of preferable, feasible and sustainable solutions can be improved with the support of evaluation tools, of a monetary or qualitative type. This paper illustrates an experimental model of "Project of economic feasibility for the exploitation of unused public buildings" called SOSTEC; this model can be used when the public decision-maker intends to verify whether the economic conditions exist for the use of forms of private public partnership to create and/or manage a work. The contribution, after the general illustration of the model, focuses on the ways how the economic-estimative aspects of the feasibility of the enhancement projects are dealt with and resolved through the use of the monetary technique, the Cash Flow Analysis.
