The new certification system for the energy performance of buildings, approved by Decree-Law 118/2013, entered into force on December 1 2013.
The new certification system, which transposed EU Directive 2010/31/EC, establishes a clear distinction between the regimes applicable to residential and non-residential buildings (eg, services and commercial buildings), with a view to simplifying and clarifying an issue of significant technical complexity.
For buildings under construction or major renovation, a provisional EPC is required before the construction or renovation takes place. However, this provisional EPC will expire if it is not converted into a final EPC once the work has been completed.
EPCs (and provisional EPCs) are valid for 10 years from the date of issue. EPCs for major services and commercial buildings are valid for six years from the date of issue. However, if there is any change in the building that could affect its energy performance, the EPC will be rendered invalid.
Apart from the owners, developers and real estate agents must now disclose the relevant EPC (or provisional EPC) number and energy performance rating in all advertisements for the sale or rent of buildings covered by the certification system.
