Energy certification


Energy certification is a set of actions and procedures that are conducted for the purpose of issuing the energy certificate that shows the energy performance of an individual building or part of it.

Every building, apartment or business premises located in a building larger than 50 m2 must have an energy certificate when selling / renting. The document is valid for 10 years from the date of issue and it contains the general information about the building, energy class of the building, certificate validity period, the information about the person who issued and drew up the energy performance certificate, information about the person who took part in the preparation of the energy certificate, energy certificate rating, data about the building’s thermal and technical systems, energy requirements, information about the use of renewable sources of energy (RES), proposals for measures, detailed information and explanation of the energy performance certificate.

In order to establish the current status of the building and the possibility to reduce energy consumption, an energy audit of the building is carried out. Residential and non-residential buildings are categorized into eight energy classes according to the energy rating scale from A + to G, where the A + is the most energy-efficient and G is the least energy-efficiant class.
