Retrofit Vs Rehabilitation: improving technological quality of the existing school building

The prerequisite of an appropriate technological retrofit design is a thorough analysis of the technical-constructive DNA, so that both the types of work that the materials to be used can be selected in relation to the specific performance deficiencies. This paper presents the results of a research funded by the Campania Region, which investigated the issues related to retrofit of existing school building, in order to improve the energy efficiency of the places for training and reduce the risks related to the functional degradation, even in the event of environmental disasters. Starting from the evaluation of the energy performance, the research has identified interventions that increase the technological quality of the buildings, according to the specific construction types and effective even in terms of costs. From a methodological point of view, the research started by the Ministry of Education Guidelines for a good school, analysing the Environmental Unit and the internal distribution system in order to verify as satisfying the functional regulatory requirements. Then, from the evaluation of the energy performance, the research has identified interventions that increase the technological quality of the buildings, according to the specific construction types and effective even in terms of costs. The energy audit has been the most effective tool to achieve these goals. Considering of the climatic and environmental features of the Campania Region, Particular attention was paid to envelope's performance according to the Mediterranean character
