Energy Performance Certificates (EPCs), or Certificado Energético, are mandatory documents in Portugal for anyone selling, renting, or constructing a property. These certificates assess a building's energy efficiency, assigning a rating from A+ (most efficient) to F (least efficient). The EPC includes recommendations for improving energy performance, such as upgrading insulation or installing efficient heating systems, which can enhance property value and reduce energy costs.

An EPC not only ensures compliance with Portuguese regulations but also promotes sustainable living by encouraging energy-saving practices. Obtaining an EPC involves an inspection by a certified energy assessor who evaluates factors like insulation, heating systems, and windows. For homeowners and buyers alike, the certificate provides valuable insights into a property's energy consumption and potential savings.
