Since the launch of the national Energy Performance Certificate (EPC) schemes, about two-thirds of European Member States (MSs) have introduced changes to their EPC formats, either to improve attractiveness and reputation, or to include stricter requirements, or both. The CA EPBD Factsheet Changes in EPCs scales and layouts - Experiences and best practices looks at examples of the types of changes MSs have implemented to modify their EPCs, what the triggers for these changes were, and how they were integrated into the existing market....

Heritage buildings, in their original condition, usually have very poor energy performance. For a multitude of reasons, it may be unreasonably expensive, or otherwise impracticable, to comply with the energy performance regulations applicable to renovation. The importance of historic buildings is recognised by both the EPBD and the EED. The factsheet Energy efficiency of heritage buildings presents in a comprehensive manner how MSs deal with energy efficiency in heritage buildings. ...

Primary factors and the EPBD The reduction in the use of primary energy for the end-uses is for the EPBD an important policy goal, both through minimum performance requirements and for EPCs. Primary energy is therefore a major metric within the EPBD, but the choice of values for primary energy factors (PEFs), which are used to calculate the primary energy content of energy delivered by different energy carriers, is at the discretion of MSs. Inevitably, there are differences between PEF values in different MSs for the same energy sources. This factsheet Primary Energy Factors and Members States Energy Regulations addresses the issue regarding PEFs in the EU, including principles, basic definitions and summary of values used by MSs....

Experiences from new buildings The move towards Nearly Zero-Energy Buildings (NZEB) in the Member States has allowed for innovative technologies to be steadily introduced into the building markets over the last few years. The purpose of the factsheet Innovative technologies is to collect and present initial experiences with new technologies in the Member States. Information has also been gathered on how Member States incorporate these technologies into their national Energy Performance (EP) calculation methods. The innovative technologies discussed in this context are demand-controlled ventilation, home-automation systems, reversible heat pumps (for cooling in summer), and advanced solar-shading systems....

Pilot projects from 13 countries Throughout the EPBD, the public sector in each Member State is expected to lead the way in the field of energy performance of buildings. New buildings occupied and owned by public authorities shall be Nearly Zero-Energy Buildings (NZEB) two years earlier than all other types of new buildings. Among the most promising public building types to act as lighthouse projects are educational buildings including school buildings. A CA EPBD collection of good practice examples of NZEB(-like) educational buildings in the different Member States (MSs) is set out in the factsheet NZEB-like Educational Buildings, including cross comparison of the used building and technical systems technologies....
