What is the energy certificate?

energy certificate

Process by which a qualification of energy efficiency is awarded to a building in the same way that it is granted to appliances such as refrigerator, washing machine, etc.
This qualification is extracted from the calculation of the energy consumption necessary to satisfy the energy demand of the building under normal conditions of operation and occupation (type of windows and system of sealing with the outside, system used for hot water, materials used in construction ,etc) .
It classifies the buildings into a seven-letter scale, where the letter G corresponds to the least efficient building and the letter A to the most efficient building according to energy consumption and CO2 emissions compared to a base building of similar typology and location.
