The Energy Efficiency Certificate is an official document . That is mandatory for all properties that are going to be sold or rent. Although interpreting the values of the scale is not difficult, since it is a value from . A to G and has a series of colors from . Green to red for a better understanding, how to calculate the energy rating . Scale is more complicat. The reason is that it requires a process of calculations that are quite complex, involving specific indices and intervals. It must be taken into account that, since the approval of Royal Decree , of April . Which regulates the procedure for the qualification and certification of . The energy efficiency of buildings, it is essential that all buildings, both new . Plant and those that have been rehabilitat, are order with a letter . Within the energy rating scale. This classification is based on CO2 emissions.
How to calcul ate the energy rating scale?
To know the rating, the first thing to do is calculate an energy efficiency rating index . To do so, it is necessary to solve a formula . It is the value of the analyzed indicator (annual CO2e emissions, annual consumption of non-renewable primary energy, heating demand, etc.) of the object building. Ir: It is the average value of the indicator of the reference stock of new buildings Russia Phone Number Data for private residential use (housing). R : It is the ratio between the value of Ir and the value of the indicator corresponding to the 10% percentile of the reference stock of new buildings for private residential use (housing). Is: It is the average value of the indicator of the reference stock of existing buildings for private residential use (housing). R0: It is the ratio between the value of Is and the value of the indicator corresponding.
What is the buildi ng’s energy label?
The values of Ir, R, Is, R0 corresponding to the different climatic zones are includ in tables publishe by the Ministry of Public Works in the . Document “Calculation of the energy efficiency of buildings” – Annex III. It must be clear that each LETTER corresponds to a Spain Phone Number List range of values of the aforementioned indices: The information you need to know about its efficiency appears on a home’s energy label. It uses a scale that calculates your consumption. As you have seen, the scale is made up of 7 correlative letters, from A to G. In this case, A corresponds to the home that is most efficient and G to the one that is least efficient. The annual energy and CO2 consumption must also appear on this label.
