An AHP-Based Methodology for Decision Support in Integrated Interventions in School Buildings

The recovery and requalification of built heritage are, in Europe and all over the world, a central issue in relation to current international policies. In recent years, there has been a considerable growth in research within this field, favoring the implementation of intervention methodologies in the real estate assets of public and private property. With this study, we intend to focus attention on the redevelopment of existing school buildings, taking into account, from an integrated perspective, dierent aspects related to energy and environmental retrofit, the improvement of seismic safety, and socio-economic assessments. A significant impact of the study that was carried out will be favoring the more disadvantaged classes and a reduction in school drop-out, which in some cases is caused by the decentralized dislocation of the complexes or by inadequate structures. The research consists of the development of a tool to support the planning and programming of interventions for school building modernization, with a view to environmental, economic, and social sustainability. In order to take into account the multiplicity of the aspects considered, among the methods of multi-criteria analysis for decision-making aims the Analytic Hierarchy Process (AHP) method was applied, which allowed us to analyze and compare dierent alternatives through evaluation criteria, reaching the definition of a priority scale. This process makes it possible to identify those interventions that achieve the best compromise between community needs and the planners’ goals. The evaluation procedure is validated through the application on a concrete case study, which is a school building located in the province of Avellino, in the south of Italy.
