The subject of this study was the definition of criteria for intervention on school buildings, protected by the Italian Cultural Heritage Code, with the aim of upgrading according to the target nearly Zero Energy Building (nZEB). The tasks required to carry out the study have foreseen the identification of a case-study representative of a common historical school building typology. Than the definition of retrofit measures has been set to meet the nZEB requirements as defined by the National implementation of the EPBD Recast, while complying with the protection constraints. Finally, the cost-effectiveness of the various interventions was also evaluated.
