We remind you that after the entry into force of decree law 311 of December 2006 and subsequent amendments, important incentives were introduced in favor of those who carry out interventions aimed at improving the energy efficiency of existing buildings. The interventions encouraged vary from the global redevelopment of the entire building, to the intervention on envelope elements (for example with external thermal insulation) or system (for example with the replacement of components with other più effi cients). All information on these incentives can be found on the ENEA website or from the relevant bodies.
