An energy performance certificate is a legal requirement when selling or renting a property and when obtaining a usage permit. Beyond compliance, the certificate gives you insight into the building's actual energy efficiency.
We carry out energy audits and issue certificates for residential and non-residential buildings. Along with the certificate you receive concrete improvement measures that can reduce energy consumption and increase the property's value.
