Energy Certification

Everything you need to know about the ” Energy Certificate “

What is the Energy Certification ?, Who should have it ? Who can bestow? …. In summary , in this post we will try to explain all the issues related to energy certification , a clear readable and easily understood by all. You don’t longer have excuses not understand about this and everything related to it . You’ll also get a group of links to the most relevant to complete and deepen the documentation if you wish more information.

What is the energy performance certificate?

In 2002 the European Parliament adopted a directive to all EU countries , where the obligation to make available to purchasers or users of a building , a certificate of energy efficiency, which should include factual information on establishing energy characteristics of the building. Since 2007 is in force in our country this obligation for new buildings . From June 2013 through Real Decreto 235/2013 obligation extends to all existing.

An energy performance certificate , including objective information on the energy characteristics of the building. Since 2007 is in force in our country this obligation for new buildings . From of1 June 2013 by Real Decreto 235/2013 obligation extends to all existing buildings. Real Decreto 235/2013 , of April 5 , whereby the basic procedure for certification of energy efficiency of buildings is approved. Watch BOE pdf file (in Spanish).

Date to enactment of the Energy Performance Certificate?

All owners that wish to sell or rent your home from next June 1 must certify the energy performance certificate or a copy thereof, a new Royal Decree published last April 13, 2013 in the Official Gazette.

What buildings fall into this legislation?

Fall under this new legislation the new buildings, buildings or parts of existing buildings to be sold or rented.

What is the certification of energy efficiency?

Aims to foster the promotion of energy-efficient buildings and investments in energy saving.

How the energy performance certificate is obtained?

The energy performance certificate of a building, house or premises is obtained from the energy consumption needed to meet the demand for heating, cooling, ventilation, hot water production and lighting. This consumption is compared to a reference building or type and class, which will vary from A for more efficient to G for the least efficient buildings buildings is thus obtained. The Certificate provides information on changes needed if you want to improve classification.

Who can perform the certification?

The technicians will conduct having the educational and professional qualifications enabled the realization of building projects or their heating systems, ie, Architects, Surveyors and Technical Architects, Industrial Engineers and Industrial Engineers. They may also issue the Certification of Energy Efficiency other technicians with specific training demonstrable official documentation on Energy Efficiency of Buildings.

Who is responsible for making this certification?

The owner of the property or part thereof shall be responsible for commissioning certification.

Who is excluded?

Excluded the following cases: open buildings, listed buildings, buildings used as places of worship or religious activities, temporary buildings with periods of use under two years, industrial and agricultural buildings in that part to workshops, isolated buildings with a floor space Total less than 50 m2 and houses that are the subject of a lease for less than four months a year time.

What is data collection?

The main data for obtaining the energy rating are the following:

  1. Datos Administrative: Address of Property, owner identification, cadastral reference, etc.
  2. Datos General: building type, year of construction, climate zone, photos, tests, etc. Geometric
  3. Definition: Uprising property.
  4. Sharpness Constructive: Constructive section of the facade, roof, interior partitions, walls, floors and walls in contact with the ground.
  5. Definición conditioning systems: Heating, cooling type, host hot water.
  6. Edificios existing: recommendations for improving energy efficiency.

How is the certificate and what information do you have?

Example of energy performance certificate:

What is done with the Certificate?

Certificate must be registered with the Registrar of the Autonomous Community to be valid. Subsequently, the certificate will be available to the competent authorities so require by inspection or other requirements.

That implies a low rating?

While the certificate has a list of measures to improve the classification will not be binding undertake them, even if the rating was the lowest.

What period of validity has and when do I renew it?

Shall be valid for ten years. The competent body of the Autonomous Community establish specific conditions for their renewal or upgrade. However if improvements are running the owner may voluntarily request an update.

How much cost is Certificate?

There is no fixed fee, the cost will be given basically by the time you need technical for data collection and subsequent calculations. Surface property and complexity of the construction are the main factors that influence the time required for data collection. If the customer has detailed plans and has all the equipment data (air conditioning, heating, boiler, etc.) can be reduced much this time. However, the price is set by supply and demand free energy performance certificates.

What is the label?

The energy label shows, among other things, the energy rating of a building. The scale of the energy rating is seven correlative letters. Letter A (most energy-efficient building) to G (least energy efficient building). Furthermore shall also include, inter alia, information on the annual energy consumption (kWh / year and kWh / m2) and Annual CO2 consumption (kgCO2 / year and kgCO2 / m2)

Where is it used?

All buildings of public or private ownership providing public services to a large number of people and therefore frequently visited by them, with a total useful floor area over 1000 m2, mandatorily displayed in a prominent place clearly visible to the public, the energy efficiency label when it is required them obtaining it. In the former category are considered including buildings for the following uses: administrative, healthcare, educational, commercial, cultural (intended for restoration, shows, meeting, sport, leisure, auditoriums, games and similar), residential and public transport people. For other buildings public display of energy efficiency label will be voluntary, and in accordance with the stipulations of the competent body of the Autonomous Community. Notwithstanding the energy efficiency label must be included in any offer, promotion and advertising to the sale or lease of real property. When the property is under contract of sale, in whole or in part, the energy performance certificate shall be made available to the acquirer.

What if I try to sell or lease without Certificate?

It may be administratively sanctioned by the competent body of the Autonomous Community for violation of the rights of consumers. Given the economic situation of the administration thought it did not let pass the opportunity as part of fundraising, especially with how easy it is to visit the estate. It can also happen that at the request of buyer or lessee the invalidity of a contract requested by lack of consumer information. If we add to this disorder economic consequences resulting from a judicial demand for energy is not provided, it is clear the desirability of possessing the Certificate.

Will there be sanctions?

If you do not have the Certificate sales may not be entered in the register , but is not scheduled a penalty specified by this fact. However an important aspect of Royal Decree Article 12.2 is dealing with the display label and it says in this regard; “Shall be included in any offer , promotion and advertising to the sale or lease of the building or building unit” . Violation of this provision shall be deemed infringement on certification of energy efficiency of buildings and also constitute infringements of consumer protection and users, so you must be very careful because the administration will not let this opportunity pass high amounts of sanctions.

What is the software to perform this certification?

Currently these free programs, along with their manuals can be downloaded in Spain from the following link Ministerio de Industria, Energía y Turismo

 The procedures in question are two computer programs :

• CE3X developed by NATURAL CLIMATE SYSTEMS , SA (UTE MIYABI FOUNDATION CENER)

• CE3 developed by APPLUS NORCONTROL S.L.U.

Calener : A computer program promoted by the Ministry of Industry, Tourism and Trade through the IDAE , with the aim of providing the Spanish professionals a tool to determine the level corresponding to a building energy efficiency. The program consists of two tools for easy user , the Calener PVY , for qualifying energy efficiency of residential buildings and small and medium tertiary use , and Calener GT , for qualifying energy efficiency of large buildings the tertiary sector.

CALENER PROCEDURE AS REFERENCE CALENER

remains the reference procedure for the energy rating of buildings, also existing, however, the development of simplified procedures CE3X CE3 and, in the case of existing buildings, solves the problem of obtaining certain data needed for CALENER introduction of the building, which can be very costly (composition 3 enclosures, etc). Furthermore, these programs cover the need for the actual classification of an existing building be proposed steps to improve your score.

TEST CONDUCTED

Computer programs have been extensively tested before their official publication. The analysis process consisted programs performing various test:

  • Test quality computer
  • Test User
  • Test accuracy comparison with CALENER

The test quality and test computer user has been made by a task of managing the National Institute of Communication Technologies (INTECO) for an assessment of the quality of software products consisting of usability testing with real users . The accuracy of the simplified procedures developed for the energy rating of existing buildings CE3 and CE3X, was determined by comparison with the reference procedure for computing the energy rating of buildings CALENER. The simulations have been carried out directly in the IDEA itself and through collaboration with the National Institute of Communication Technologies (INTECO). Total hours approximate simulation for comparative CALENER -CE3 and CE3X was 4,000 hours, working with multiple computers in parallel.

As a result of the test battery that both programs have passed, we have detected some problems that have been solved before departure to production application.

How long does it take to be issued a certificate of energy efficiency?

After the inspection of the property being certified, the deadlines for delivery of energy performance certificate vary depending on the following variables:

  1. Tiempo of development by professional technician or certifier, the energy performance certificate and subsequent assignment of the rating on the energy label. (Approximately 3 days)
  2. Depending the Autonomous Community, record energy performance certificate. Each Autonomous Community establishes the criteria for registration.
Depending mainly on these two factors, the corresponding energy performance certificate will be issued. Since the energy performance certificate is mandatory before signing any transaction of sale and / or rental is recommended to request the certificate of energy efficiency or energy certificate with a minimum of 30 days before signing the contract.
Glossary energy certification:
Building: a roofed construction with walls, for which energy is used to condition the indoor climate; You can refer to a building as a whole or parts thereof that have been designed or altered to be used separately.
Energy efficiency of a building energy consumption deemed necessary to meet the energy demand of the building under normal operating conditions and occupation.
Energy rating of a building: expression of the energy efficiency of a building is determined according to a calculation methodology and energy indicators expressed by the energy label.
Energy label: badge that indicates the level of energy performance rating obtained by the methods considered as recognized document.
Nominal thermal power installed: Maximum output laid down and guaranteed by the manufacturer, can supply equipment continuous operation while complying with the yields declared by the manufacturer.
Centralized systems: those in which the production of heat or cold is unique for the entire building, performing its distribution from the power station to the corresponding homes or premises by thermal fluids.
