Il processo di transizione energetica del patrimonio costruito in Italia. Riflessioni e prospettive verso il 2033

The energy transition process of the built heritage sets numerous technical, environmental, architectural, conservation, regulatory, and economic challenges. Furthermore, climate change, with the consequent rise of average temperatures and the increase in extreme weather phenomena, establishes increasing pressure on improving the efficiency, not just energy, of buildings, making adopting suitable solutions even more urgent. In this context, the contribution addresses two aspects to highlight the characteristics that distinguish today’s situation. The first concerns the current regulatory framework with an enlarged vision to the recent revision proposal of the Energy Performance of Building Directive (EPBD), part of the ‘fit for 55’ package. The second focuses on the energy efficiency interventions carried out in Italy following the introduction of the so-called ‘Superbonus 110%’ with a first interpretation of the results provided by ENEA on the interventions carried out up to 2021. From the analysis of these two aspects, it is possible to identify some key points for promoting a model capable of combining the protection of the built heritage with the sustainability and effectiveness of energy efficiency interventions.
