Italy

Since 2002, the transposition of the EPBD has been entrusted to the Ministry of the Environment and Energy Security. This Ministry is responsible for the necessary procedures to integrate the provisions of the Directive into national legislation, but the process also involves other entities and institutions. ENEA, as the National Agency for Energy Efficiency, provides technical-scientific support to the Ministry and therefore plays a significant role in the process of transposition and implementation of the EPBD. CTI, as part of the National Standardization Body, contributed to establish the common calculation methodology. The regional/provincial authorities manage and are in charge of monitoring and control.

Italian regions and autonomous provinces (a total of 21 authorities) have final jurisdiction in energy topics. For this reason, in the past, several regions implemented the EPBD separately, thereby creating a very heterogeneous and complex regulatory framework. The current legislation provided an advanced harmonisation of the EPBD implementation across the national territory.

Decree 192/2005, set the basis for the EPBD implementation in Italy. It was followed by several complementary legal acts updating the minimum energy performance requirements for buildings, building components and technical building systems, while extending the calculation to cooling and lighting systems and providing guidelines for energy performance certification (2009) and defining requirements for assessors as well as specifications for the inspection of technical building systems (2013).

Law 90/2013 has implemented Directive 2010/31/EU, introducing significant changes to the 2005 implementation. In June 2015, three inter-ministerial decrees (26 June 2015) completed the EPBD transposition, which also established stricter minimum requirements for new buildings and major renovations, defined NZEB, as well as rules for taking RES in buildings into account, and provided new national guidelines for Energy Performance Certificates (EPCs).

Until the adoption of Directive 2024/1275, the three inter-ministerial decrees (26 June 2015) apply.

A national Information System (SIAPE) for Energy Performance Certificates (EPCs) has been created, and it now includes data from 20 out of 21 regions/ autonomous provinces. A national register for the inspection of technical heating/cooling systems is under development, aiming to collect the data from the different regional/ provincial databases already in place.

The transposition of the recast Directive (EU) 2024/1275 into the Italian legislation is currently ongoing, with a group created for this purpose and coordinated by ENEA.
