Certification of buildings

Provisions regarding the energy performance certification of new buildings have been adopted by the Government at a national level as the ‘National Basic Procedure for energy certification’ through the Royal Decree 47/2007 of the 17th of January 2007, published on the 31st of January 20074

. By the

Certification table for low energy class (Class D) for new dwellings in Madrid.

term ‘Basic procedure’ it is meant that other authorities with jurisdiction, such as the Autonomous Communities, can regulate and complete the National system, by giving more detailed provisions on what the control and inspections refer to. All parties and administrations involved are co- ordinated on a day to day basis by a National Advisory Commission created by the Decree, which studies the updates of target values and provides interpretations and solutions to problems or doubts raised by the new legislation.

Certification is obligatory for new buildings when the application for a building permit was made to the Local Authorities after the 31st of October 2007. This applies to all types of buildings (residential, public, commercial etc.).

Regional Governments have the authority to decide whether it is mandatory or not to display this certificate at the main entrance of the building. In any case, it is mandatory to display it for public buildings over 1.000 m2.

Certification of existing buildings is still in the process of administrative approval, with another relevant Royal Decree under way. As yet, it is not mandatory when selling or renting, buta ‘Basic procedure’ for the certification of existing buildings is expected to be ready and mandatory in 2009.

As for the calculation of energy demands, the ‘National Basic Procedure’ for energy certification allows for two possible methods: a simplified method (that includes all validated procedures approved by the Certification Commission, in addition to the already existing simplified methodology for dwellings based on the 12 tables for the different climatic areas) and a complex method. The latter requires the use of a software tool, the official one being ‘CALENER’.

So far, there are two different versions of CALENER: CALENER_VYP (for dwellings and small tertiary sector buildings)5 tertiary sector buildings)6

and CALENER_GT (for big .

All matters pertaining to the control, inspection and registration of the energy performance certificates of buildings are under the authority of Regional Governments. Each region has its own internal structure. So, for example, certification will fall under the authority of the Industrial, Dwelling or Environmental Department, depending on the region. Thus, there are 19 different regional schemes in Spain.

Inspection of boilers and air conditioning

CALENER

The inspection of boilers is already covered by the Regulation on thermal installations in Buildings (RITE), since its first version that was approved in 1982, revised in 1986, and applicable since 1998. This last RITE version was revised and approved by the Council of Ministers on the 20th of July 2007, taking into account the new EPBD minimum requirements for thermal installations, including AC/HVAC energy efficiency inspections.

At the same time, technical procedures for HVAC systems are included in this revised version of RITE. Details can be obtained from the Ministry’s
