Abstract

Il settore dell'edilizia scolastica pubblica offre grandi opportunità di efficientamento energetico e di riduzione delle emissioni di CO2. In questa ricerca viene proposto un metodo per la valutazione energetica degli edifici scolastici. Il metodo implementa semplici informazioni di input collegate a simulazioni dinamiche. L’obiettivo principale è quello di valutare l’impatto energetico, ambientale ed economico delle diverse proposte di rigenerazione ed efficientamento, combinando l’integrazione del sistema verde. L’edificio scelto come caso studio, che presenta caratteristiche costruttive e termofisiche seriali e molto diffuse, consente di estendere la validità dei risultati ottenuti a casi e condizioni ambientali e contestuali simili. I risultati hanno evidenziato l'importanza di sviluppare strategie site-specific e soluzioni green energy, per adattare in modo ottimale qualsiasi intervento alle caratteristiche architettoniche, tipologiche e impiantistiche della scuola. L’esempio proposto è un caso prototipale affinché i Comuni e le Pubbliche Amministrazioni, che posseggono la maggior parte delle scuole in Italia, possano utilizzarlo come strumento di conoscenza base per progetti futuri orientati alla transizione energetica, ma anche per una formazione specifica dedicata.
