This report leverages the data collected from the crossCert project to identify differences and best practices in quality control mechanisms across crossCert countries. We aim to propose a harmonized framework to enhance these mechanisms. The report examines critical aspects of Energy Performance Certificate (EPC) assessments that influence quality control, aiming to standardize these processes across Europe.
To achieve our goal, this report incorporates data from the C-testing and L-testing reports, feedback from project partners via questionnaires, and further information from crossCert project reports. Additionally, we considered findings from similar projects like QualDeEPC, XTendo, and the Concerted Action EPBD reports.
Our findings highlight significant differences in EPC assessments among crossCert project countries, including calculation methodologies, EPC software, the EPC document itself, and the qualifications required for assessors. This report focuses on these aspects as critical factors in EPC quality control and proposes a framework applicable to any EPC methodology, aiming to establish key features of robust quality control mechanisms.
