The present research is focalized on public-private partnership (PPP) procedures as a driving force of urban sustainable development. The paper intends to point out the relevant role played by the public administrations in the implementation of these mechanisms aimed at degraded urban area renovation, public property assets enhancement, or ex novo realization. In this sense, in the existing reference literature, the private investor tasks and risks have been often explored, neglecting the significant public entities position. The efficiency in the use of the PPP is verified through the discounted cash-flow analysis (DCFA) implementation: the assessment of the costs and the revenues derived from the project allows the private investor to verify the financial feasibility of the initiative. In the context outlined, the public administration could contribute to the success of the intervention through a periodic fee paid to the private investor in order to ensure the financial convenience of the project. In the present research, a functional reconversion operation related to a building located in the small town of Cesano Romano (Italy) and carried out through the PPP operational tool, has been illustrated. In the analysis, a public monetary amount has been considered and determined, able (i) to guarantee the financial sustainability for the private investor and (ii) to comply with the regulatory constraints in the Italian context. Finally, a scenario analysis has been developed to identify the situation/s in which public participation is necessary for the convenience of the initiative and to quantify this monetary amount.
