Implementation of the Energy Performance in Buildings Directive

The EU Energy Performance in Buildings Directive began implementation in Spain for new buildings (and major renovations) on 30 October 2007. Software tools were developed and distributed free of charge for residential and small business buildings as well as for large tertiary buildings. In addition, a simplified certification methodology for residential buildings was approved by Royal Decree 47/2007 on 19 January 2007. In the course of 2007 several regulations were passed on the energy efficiency of buildings, notably the Building Energy Certification (CER) and the Regulations on Building Heating Installations (RITE), approved by Royal Decrees RD 47/2007 and RD 1027/2007 respectively. These approvals together with the Technical Building Code (TBC) contribute to the partial transposition of the Directive 2002/91/EC on the energy efficiency of buildings into the Spanish legislation. The TBC includes a Basic Energy Saving Document and covers regulations on: 1)Limitations on energy demand (heating and air-conditioning) 2) Performance of Thermal Installations/Air-conditioning systems 3) Efficiency in the indoor lighting installations 4) Minimum solar thermal contribution (hot water), and 6) Minimum PV contribution.
