Nel corso dell’ultimo decennio, il contesto nazionale ed europeo è stato teatro di un lungo ed intricato iter di produzione normativa dedicata al miglioramento degli standard energetici del settore edilizio. I lavori hanno preso per buona parte il via dall’impegno, formalizzato attraverso il Protocollo di Kyōto, di ottenere una riduzione dei livelli di concentrazione dei gas ad effetto serra nell’atmosfera, con lo scopo di frenare il fenomeno di surriscaldamento globale in atto. Ad oggi in Europa gli edifici sono ancora responsabili del 35% dei consumi energetici totali e del 38% delle emissioni serra totali, principalmente per il soddisfacimento dei fabbisogni per riscaldamento, nonostante un calo di quasi il 10% del fabbisogno energetico da parte del settore residenziale da inizio millennio ad oggi. L’Italia si dimostra in controtendenza rispetto al trend europeo, evidenziando una lenta ma costante crescita dei consumi: questo fenomeno dipende senza dubbio dall’elevata età media del proprio patrimonio immobiliare, dal momento che circa il 60% degli edifici residenziali presenti oggigiorno sul territorio italiano è stato costruito prima del 1977, cioè prima dell’entrata in vigore delle prime norme sull’efficienza energetica degli edifici. Gli incentivi per interventi di efficientamento energetico già proposti negli ultimi anni sono stati estesi nel corso del 2021 per supportare il settore edilizio gravemente colpito dalla crisi legata alla pandemia di Covid-19: in particolare, con il Decreto Rilancio del 19 maggio 2020 viene elevata al 110% l’aliquota di detrazione delle spese sostenute per specifici interventi in ambito di efficienza energetica. Ai fini di un esame più efficiente delle caratteristiche energetiche del sistema edilizio è evidente tuttavia l’importanza della costituzione di un quadro conoscitivo capace di restituire, per il singolo fabbricato, informazioni puntuali ad esso esclusivamente riferite.

Abstract
Over the last decade, the national and European context has been the scene of a long and intricate process of legislative production dedicated to improving energy standards of the building sector. The works have largely started with the commitment formalized through the Kyōto Protocol, in order to obtain a reduction in the concentration levels of greenhouse gases in the atmosphere, with the aim of curbing the phenomenon of global warming in progress. Buildings in Europe are still responsible for 35% of total energy consumption and 38% of total greenhouse emissions to date, mainly for meeting heating needs, despite a decrease of almost 10% in energy needs by the residential sector since the beginning of the millennium to date. Italy proves to be in contrast with the European trend, highlighting a slow but constant growth in consumption. This phenomenon undoubtedly depends on the high average age of its real estate assets, since about 60% of residential buildings present today in the Italian territory was built before 1977, i.e. before the entry into force of the first energy-efficiency standards of buildings. The incentives for energy efficiency measures, already proposed in recent years, have been extended during 2021, in order to support the construction sector severely affected by the crisis linked to the Covid-19 pandemic. In particular, with the Decree of May 19th 2020 on economic recovery, the deduction rate regarding expenses incurred for specific intervention in the field of energy efficiency was raised to 110%. Creating a cognitive framework able to provide, for the single building, precise and accurate information is crucial in order to provide a more efficient exam of the energetic features of the building system.I documenti in UNITESI sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
