ENERGY PERFORMANCE CERTIFICATE
BECOMING FAMILIAR WITH THE INFORCEMENT OF THE SPANISH ENERGY PERFORMANCE CERTIFICATE
Since June 1st 2013 Spain's Energy Performance Certificate (Certificado Energético) has come into enforcement by Royal Decree (Real Decreto 253/2013), being a transposition of EC directive 2010/31/EC.
This act enforces the compulsory issue of an Energy Performance Certificate - similar to that of electrical home appliances- for all residential and commercial premises that are for sale or rent. The label is to be displayed in all publicity announcing the sale or rental of premises.
The certificate has to be obtained through a professional technician who has the pertaining qualifications to undertake the inspection of the home or commercial premise, to produce the necessary plans and blue-prints of the building (if these are not available) and proceed with the testing of all the constructive elements which constitute the enclosure of the building (façade, windows, roofing, all elements that are in contact with the ground) as well as all comfort generating installations and appliances, such as hot water systems, heating, ventilation and air conditioning.
Once all the due checks have been made, the certified results have to be presented to the pertaining public entity, - in the case of Andalucía it would be the "Consejería de Innovación e Industria de Andalucía". The hereby obtained registration number constitutes the legal document that is required for the sale or rental of premises that are either in project phase, under construction or already finalized. The certificate has a valid lifetime of 10 years. The actual label is a resume of the results obtained after all the submitted data have been analysed, and it indicates the CO2 emissions per square meter and year, generated by the inhabited property.
What is it useful for?
At first glance this is an indicator of the energy consumption that is required to achieve a comfort condition of the home. Therefore it is a useful pre purchase or rental tool that allows for an approximate calculation of the potential energy consumption that a premise generates, being able to estimate the cost of electricity, gas, fuel etc. for the new acquisition.
What information does it provide?
Taking the example of an Energy Performance Certificate for an existing home, the most important aspect it offers is a list of recommendations on actions that can be taken in the premise in order to improve the efficiency conditions and reduce energy consumption. The list of actions provides an approximate estimate for each item and investment recovery schedule.
For instance on a property that presents deteriorated exterior carpentry, the replacement cost for the out-dated windows and doors as well as the consequent reduction of energy consumption for heating and air conditioning can be estimated, along with the time-frame for the investment recovery related to the energy savings.
Why do properties in Spain have such low classification?
As explained in above chapters the certificate indicates the CO2 that a property produces, yet not only relating to the direct emissions through fuel or gas combustion in the premise, but also to those of the origin of the electric energy that it consumes.
As can be clearly appreciated in the graph, the major source of electric energy production in Spain relates power stations, which generate electricity through the firing of fossil residuals, mainly coal. This is the reason for the high percentage of CO2 emissions in Spain's electricity generation.
The obvious conclusion of the exposed is that the electricity consumed in Spanish homes constitutes one of the highest effects of penalization for the country in terms of CO2 emissions.
