The Energy Performance Certificate (EPC), as defined in Directive 2010/31/EU of the European Parliament and of the Council and in Law No. 4122/2013 (Greek Government Gazette 42/19-02-2013), is a document licensed by the Ministry of Environment & Energy, which informs the user/owner about a building's energy performance.

The Energy Performance Certificate classifies the buildings into energy categories in a scale from A to G, where category A represents the buildings or the building units with the highest energy performance.

The Energy Performance Certificate is issued by the energy auditor, who has been registered into Buildingrcert, the energy auditors’ special register, and is issued along with recommendations for energy saving measures, with the purpose of reducing the operating & energy costs of a building.

Energy audits are an important means of diagnosing the energy situation of the existing buildings, of classifying them into an energy category and exploring the possibilities of improving their energy situation. The classification of the building into an energy category is made based on the ratio of the building’s consumption to the consumption of the reference building.

Issuing an EPC is required for all the buildings with a total surface area of above 50m2 that cover basic uses (housing, both permanent housing and cottages, offices, commercial uses, assemblies, education, temporary residence, health and social care, etc.), as follows:

New and radically renovated:

  • After the construction of each new or radically renovated building is completed

  • Existing:

  • for each sale-purchase of a single building and sale-purchase of a part of a building (e.g. apartment)

  • for each rental of a single house and rental of a part of a house (e.g. apartment), used as residence and as offices

The EPC is also obligatory for the inclusion of residential buildings in the “Household Energy Efficiency” program.
