Home energy efficiency certificate: what it is and what it is for

This Thursday, October 21, World Energy Saving Day is celebrated. A date that serves to make citizens aware of the importance of , and that encourages them to change consumption habits and guide them towards greater respect for the environment.

One of the areas where more action can be taken in this matter is real estate. Since 2013 there is the well-known energy certificate in which the energy efficiency of a building or part of it is detailed. Its objective is that future or tenants can verify the reference values ​​that allow the energy efficiency of a building to be assessed.

This certification -which expires in 10 years- has a scale that goes from A to G, with A being the most efficient qualification, and G, the least efficient, according to the Casavo proptech.

The floors in farms older than 30 years can obtain a maximum “D” rating, so it would not be possible to improve them until the most efficient certification.

According to data from the Institute for Energy Diversification and Saving (IDAE), 84% of homes with energy labeling in Spain are in the last three positions in the table, with letters E, F and G. Also, if we focus in the specific case of Madrid, only 937 of the more than 500,000 registered in consumption of existing buildings reached the letter A.

Failed in energy rating

56.3% of Spaniards do not know the energy rating of their home. This is one of the main conclusions of the Isover & Placo® Barometer on households. Regarding the efficient use of energy in the home, that is, the actions aimed at reducing the energy bill, improving the comfort, well-being and health of the inhabitants of the home, the study confirms that there is a general interest on the part of the Spaniards to favor the energy efficiency of the house (83.1%); although 54.8% affirm that they do not have the economic capacity to do so.

In addition, saving is the main reason for improving the energy efficiency of the home (for 74.2% of those surveyed); followed by the improvement of comfort (59.1%); concern for the environment (45.3%); improvement of sound insulation (35%); and the revaluation of housing (19.9%).
