Energy Performance Certificate – EPC
• Clear and reliable information on the energy Clear and reliable information on the energy performance of the building: amount of energy to performance of the building: amount of energy to meet the different needs for heating, hot water meet the different needs for heating, hot water heating, cooling, ventilation and lightingheating, cooling, ventilation and lighting..
An EPC, not being older than ten years, will be made available to the new owner/tenant when purchasing or renting a flat or building. EPC accompanied by recommendations for the cost-effective improvement of the energy performance.All public buildings over 1000 m2 have to possess an EPC, and to display it prominently.
