Obligation for renewable integration in new or existing buildings

Annex 3 of Legislative Decree no. 28 of 2011, transposing the RED Directive, identifies the obligations to integrate energy from renewable sources in new buildings or buildings undergoing major renovation, in force since 31 May 2012. The requirements are currently set in terms of percentages (increasing per year) of coverage with renewable energy sources of the thermal energy needs of the building. In particular, it is expected that in the case of new buildings or buildings undergoing major renovation, at least 50% of thermal energy consumption is met from renewable sources.
With the entry into force on 15 December 2021 of Legislative Decree no. 199 of 8 November 2021, which implements EU Directive 11/12/2018, no. 2001 (known as RED II), new provisions are introduced regarding renewable sources and new buildings or buildings subject to significant renovations. The Decree increases the coverage of energy consumption from renewable sources to 60% (up from the previous 50%). This percentage is valid for private buildings, and its achievement becomes mandatory 180 days after the date of entry into force, i.e. from 13 June 2022. For public buildings, the quota to be met is 65%.
