The Energy Performance of Building Directive (“EPBD”) was transposed in Spain by means of three royal decrees:
Royal Decree approving the Technical Building Code (“CTE”), approved by the Council of Ministers on 17 March 2006;
Royal Decree on the Basic Procedure for Energy Performance Certification of new buildings, approved by the Council of Ministers on 17 January 2007. The regulation for existing buildings is pending approval as explained below; and
Royal Decree approving the review of the current Regulations for thermal installations in Buildings (“RITE”), which was approved by the Council of Ministers on 20 July 2007.
A fourth decree will be further added to the above, to legislate on the energy certification of existing buildings, and which will complete the transposition of the EPBD to the Spanish legal system. It is expected to be approved during 2011. Nevertheless, according to the current legislation, existing buildings must comply with the same minimum requirements as new ones, i.e when building rehabilitation, enlargement or renovation is carried out on a building with a useful area in excess of 1,000 square metres.
The format of the energy performance certificate for new buildings is published in Royal Decree 47/2007. It displays the annual primary consumption of energy of the building and, apart from the energy rating achieved, its CO² global emissions.
The energy rating scale in Spain ranges from A (very high performance, involving a high contribution of renewable energies in the building consumption) to G (which represents low performance).
