Deliverable D8.2: Outline of energy certification system

This report provides an overview of the Energy Performance Certificate of the EFFESUS case studies countries, as well as EU projects, certification methods and tools for districts and historic buildings. The matching between EFFESUS key performance indicators developed under the project and indicators of the seven commercial methodologies of the district certification show that almost all existing methodologies are mostly focused on the environmental aspect rarely taking into account economic aspects or energy consumption. Therefore, a new holistic certification such as the EFFESUS approach is recommended for future evaluation of energy efficiency for historic districts.
