In Portugal, energy certificates for properties are known as "Certificado Energético" or "Certificado Energético de Edifício" (CEE), and they are required by law when a property is being sold, rented, or advertised for sale or rent. The main purpose of these certificates is to provide information about the energy efficiency of a building to potential buyers or tenants.

The energy certificate provides an energy efficiency rating for the property, ranging from A+ (very efficient) to F (very inefficient). It also includes recommendations for improving the building's energy performance. The goal is to raise awareness about energy consumption and promote the use of more energy-efficient buildings, thus helping to reduce greenhouse gas emissions and combat climate change.

In summary, the energy certificate requirement in Portugal serves to promote energy efficiency, reduce environmental impact, and provide transparency and information to individuals interested in purchasing or renting a property.

Having an energy certificate for your property in Portugal is important for several reasons:

Legal Requirement: It is a legal requirement in Portugal to have an energy certificate when selling, renting, or advertising a property for sale or rent. Failure to comply with this requirement can result in penalties.

Transparency and Information: The energy certificate provides important information about the energy efficiency of a building to potential buyers or tenants. This transparency allows them to make informed decisions and compare the energy performance of different properties.

Environmental Impact: Energy efficiency is an important factor in reducing the environmental impact of buildings. By providing information about a property's energy efficiency, the energy certificate contributes to raising awareness about energy consumption and promoting the use of more energy-efficient buildings.

Marketability: Properties with higher energy efficiency ratings may be more attractive to potential buyers or tenants, as they can lead to lower energy bills and a reduced environmental footprint.

Overall, having an energy certificate for your property in Portugal is important not only to comply with legal requirements, but also to provide transparency, promote energy efficiency, and potentially enhance the marketability of your property.
