At 2 Hèlix Enginyers, we handle the fast and certified processing of energy efficiency certificates (EEC) for all types of properties. This document has been mandatory since 2013 for any home or business premises to be sold or rented in Catalonia and is now an essential tool for building sustainability and energy performance.
What is an energy efficiency certificate?
It is an official document issued by a qualified technician (engineer, architect or technical architect) that evaluates a property’s energy consumption and CO₂ emissions. The result is classified with a letter ranging from A (highest efficiency) to G (lowest efficiency) and includes recommendations for improvement.
Besides being a legal requirement, the certificate is a valuable tool to understand a building’s energy performance, reduce consumption and increase its market value when selling or renting.
