Do you intend to rent an address and want to save on your electricity bill? To do this you must know what your energy rating is and compare the selected homes.
But what is the energy rating?
It is a measure that calculates the annual energy consumption necessary to satisfy the energy demand of a property under normal conditions of occupation and operation, including heating, lighting, hot water production, cooling and ventilation.
On April 13, 2013, Royal Decree 235/2013 of April 5, https://www.boe.es/buscar/act.php?id=BOE-A-2013-3904 was published, approving the basic procedure for energy certification of buildings, forcing all homes for sale or rent to have a certificate of energy efficiency.
It can be used in both new and existing homes. If it is a new house, it allows buyers to compare the energy efficiency of the properties that are among their options, called Project Qualification. Thus, once a year has elapsed, an energy audit is carried out in order to know the actual energy consumption and grant the definitive energy certificate.
On the other hand, if it is an existing house, they can use the report to determine the most efficient ways in which energy efficiency can be improved.
It is determined through an Energy Efficiency Certificate issued by a competent technician and with a maximum validity of 10 years from the date of issue.
Energy rating scale.
The energy rating scale is seven letters and varies between the letters A (most efficient building, consumes up to 90% less energy than one that is cataloged with the lowest level) a class B (consumes up to 70% less of energy) and one of class C (consumes up to 35% less energy) until arriving at housing type G (less energy efficient building).
As an example, it means that it could be estimated for a typical dwelling with an average consumption of € 50 / month, it would mean that:
- A ++: Energy consumption less than 30% of the average. I would spend less than the average with an amount of €15.
- A +: Energy consumption between 30% and 42% of the average. I would spend less than the average with an amount of €15 to €21.
- Energy consumption between 42% and 55% of the average. I would spend less than the average with an amount of €21 to €27.50
- B: Consumption between 55% and 75% of the average. I would spend less than the average with an amount of €27.50 to €37.50.
- C: Consumption between 75% and 90% of the average. I would spend less than the average with an amount of €37.50 to €45.
- D: Consumption between 90% and 100% of the average. I would spend the average with an amount of €45 to €50.
- E: Consumption between 100% and 110% of the average. I would spend the average with an amount of €50 to €55.
- F: Consumption between 110% and 125% of the average. I would spend more than the average with an amount of €55 to €60.
- G: Consumption greater than 125% of the average. I would spend more than the average with a minimum amount of €62.50.
It must be taken into account that the aforementioned example is an estimated weighting of the final cost according to the energy rating.
And finally if you want to improve your energy rating, making a series of changes such as thermal insulation through a double glazing in the windows as well as placement of blinds or awnings. As well as renovating your appliances and light bulbs to class A.
