The energy improvement of monumental buildings. An investigation protocol and case studies

In this paper, starting with a review of the current problems on the subject of the energy improvement of historic buildings, the main normative references are discussed, as well as the most recent European guidelines and orientations. These orientations and guidelines are methodologically consistent with the study protocol that is proposed and from which emerges the centrality of both the compositional and technical solutions that are planned for the property, and the results from the economic-financial evaluation. The case study of the Convento dello Spirito Santo in Pellezzano (SA), developed in relation to the selection of interventions that are technically compatible with the historical and architectural value of the building, highlights how on-site tests are essential so as to create a database that may be useful for improving the general intervention principles as part of a continuous feedback process and source of any subsequent corrections
