What is the energy certificate?
Do I need an Energy Efficiency Certificate (EEC)?
Yes, the EWC is a legal requirement for the purchase or rental of real estate.
The energy rating is the result of the calculation of the energy consumption necessary to satisfy the energy demand of the building under normal operating and occupancy conditions. It classifies buildings within a series of seven letters, 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.
Which buildings are obliged to have an EWC and which are excluded?
The following are obliged to have the EWC:
- new construction buildings.
- Existing buildings or parts of buildings that are sold or rented to a new tenant. Part of a building means a unit, floor, flat or flat in a building or premises intended for separate use or under separate legal ownership, designed or modified for separate use.
- Existing buildings or parts of buildings in which a public entity occupies a total useful floor area of more than 250 m2 and which are regularly frequented by the public.
- Buildings and monuments that are officially protected because they form part of a designated environment or because of their particular architectural or historical value, where compliance with the requirements of the decree would unacceptably alter their character or appearance.
- Buildings or units of buildings used exclusively as places of worship and for religious activities.
- Temporary constructions with an expected period of use of two years or less.
- Industrial and agricultural buildings, in the part destined for workshops, industrial and agricultural non-residential processes.
- Buildings or units of detached buildings with a total useful floor area of less than 50 m2.
- Buildings to be purchased for major renovation or demolition.
- Existing residential buildings or parts of buildings used for less than four months in a year, or for a limited time during the year, and with an expected energy consumption of less than 25% of what would result from year-round use.
Does the EWC have an expiry date?
The energy performance certificate will have a maximum validity of 10 years. After this period, it will have to be renewed.
However, the certificate can be updated voluntarily if there are variations in aspects that affect its energy efficiency and therefore can modify its energy rating and certificate.
