CrossCert project is creating a testing methodology for EPCs and the related certification services. It seeks to improve accuracy and usability of the EPCs, promote people-centred designs, and increase homogeneity of EPCs across Europe. It also seeks improvement in areas of training of certified EPC issuers, EPC promotion and marketing, and linkage between EPCs and related concepts, such as Smart Readiness Indicators, Building Logbooks, Building Renovation Passports, and one-stop-shops for building retrofitting.
