The Technical Building Code (TBC), approved by Royal Decree 314/2006, of 17th March, is the new regulatory framework that establishes the demands to be met by buildings in terms of the basic security and living conditions requirements, established in turn in Law 38/1999 of 5th November, the Town Planning and Development Law (LOE). To enhance innovation and technological development, the TBC has adopted a more modern, international approach in the field of building regulations: codes based on features and objectives.
Royal Decree 315/2006, of 17th March, also enabled the creation of the Council for Sustainability, Innovation and Quality in Building. It is from this Council that depends the Commission on the Technical Building Code for anything related to assistance and counselling for its application, development and updating.
The Technical Code has a Basic Document on Energy Saving, which establishes the basic demands in energy efficiency and renewable energies to be met by the new buildings and the ones to be refurbished or rehabilitated. Its drafting and coordination counted on the collaboration of IDAE, which provided advice to the Ministry of Housing.
This Basic Document is made up of the following sections:
HE.1: Restriction of energy demand (heating and cooling).
HE.2: Performance of thermal installations.
HE.3: Energy efficiency in lighting installations.
HE.4: Minimum solar to sanitary hot water.
CHEQ4, aplicación gratuita para validar el cumplimiento del CTE de las instalaciones solares térmicas
HE.5: Minimum PV contribution to electric power.
The TBC partially transposes Directive 2002/91/EC, 16 December 2002, on the energy efficiency in buildings, as regards the minimum requirements to be met on energy efficiency.
All the information about the Basic Document on Energy Efficiency of the Technical Building Code the is available at the official site.
