Energy certification for buildings makes it possible to provide consumers with information on the energy performance of buildings, which includes reducing energy use costs, improving thermal comfort and accessing finance and tax benefits.
WHAT IS THE ENERGY CERTIFICATE AND WHAT IS IT FOR?
The energy certificate is the result of a decree-law no. 118/2013 of 20 August, and must always be presented in the case of the sale or lease of a property. In this way, anyone who wants to buy or rent has an additional decision-making tool, based on energy efficiency.
The EC, on the first page, indicates the energy class (similar to what happens with household appliances) on a scale from A + to F and presents the performance for space heating, space cooling and domestic hot water. It also contains an indicator with the percentage of renewable energy that covers the energy consumption of the property.
In addition to this information on general energy performance, the EC also contains detailed information on the walls, floors, roofs, windows and installed equipment, indicating its contribution to energy consumption.
Finally, but no less relevant, the EC contains a set of improvement measures recommended by the PQ, which can be consulted by the owners and contains information on the approximate amount of investment to be carried out, as well as the savings generated with its implementation.
