Sustainable reuse of public real estate assets meeting structural, conservation and territorial needs

Currently, the recovery of existing buildings assumes a fundamental role, especially the restoration and reuse of the large state-owned properties characterised by significant cultural values, but often underutilised or even abandoned. This wide patrimony can instead represent an opportunity to satisfy the still existing needs of settlements, infrastructures, and services, without further consumption of land. The paper analyses the problem of integrating the conservation-architectural-social criteria for defining new uses of state-owned buildings with the need to meet structural requirements and performance according to current Italian technical standards for construction. A methodological protocol is proposed, based on the definition of sets of indicators, aimed at quantifying the degree of sustainability of new use design hypothesis according to the impact in terms of demand for structural performance upgrading compared with the overall sustainability of the intervention. The methodology application to the case study of a military building is presented and discussed.
