The Energy Performance Certificate (EPC), also known as Świadectwo Charakterystyki Energetycznej (SCHE), is a document assessing the energy efficiency of a building, based on theoretical calculations of energy consumption for heating, cooling, ventilation, lighting, and hot water supply according to the methodology described in the REGULATION OF THE MINISTER OF DEVELOPMENT AND TECHNOLOGY dated March 28, 2023, amending the regulation on the methodology for determining the energy performance of a building or part of a building and energy performance certificates.
The certificate is a mandatory document that the owner of a property must have in the event of sale or rental of the property or its space. From April 2024, according to the new regulation, possessing separate certificates is also required for individual rental spaces. Lack of a prepared certificate may result in a penalty.
The SCHE provides a general picture of how energy-consuming the building is according to its design and technical specifications. This document is an important tool when deciding on the modernization of the object and striving for compliance with sustainable building requirements and ESG standards.
Energy Performance Certificates (EPCs) play a crucial role in assessing a building’s energy efficiency, although it is worth noting that the values on the certificate may differ from actual energy consumption. EPCs are based on theoretical calculations considering heating, cooling, ventilation, and lighting according to the design, but actual energy consumption takes into account operational variables, such as irregular building use, additional consumption (e.g., by office equipment), and dynamic weather conditions.
Furthermore, EPCs do not cover so-called process energy, such as energy consumed by servers, external lighting, and electric chargers. This causes the actual energy consumption, measured according to the CRREM methodology, to be much higher than the values indicated by the certificate. Although EPCs assist building owners and investors in making decisions. Current simplifications and limitations make forthcoming methodological changes aim at reducing the discrepancies between theoretical values and actual energy consumption.
