Single countries' Energy Performance Certificates have various calculation approaches. crossCert now published a technical comparison of EPC systems to review the approaches to the assessment across chosen member states.
By conducting this review, EPC approaches are categorised based on type of calculation methodology used, methods of input data gathering, use of real building and/or energy data, and outputs generated from the EPC process. This categorisation will aid later analysis in the project, where crossCert will investigate the impact that country-specific EPC choices have on EPC outputs, and any consequences of these outputs.
