The Danish Energy Performance Certificate 1. 2. 3. 4. 5. SBi – 04/11/2020 EU Energy Performance Building Directive Danish Principles User access Scientific use of EPC data Identification of energy renovation opportunities 2
1. Energy Performance Building Directive The EU EPC legislations Adopted 2002 1997 Danish EPC Implementation 2006 SBi – 04/11/2020 Revision 2018 1998 Austrian EPC EPBD 2000 Recast 2010 2005 2010 2015 2020 3
2. Danish principles Asset rating: Building registration, building data collection and computation/calculation of each individual EPC rating SBi – 04/11/2020 4
2. Danish Principles Six stairs off complexity: Costs and quality Six ‘stairs’ of costs. Full operational rating starts from stair 2 and full asset rating from stair 5. SBi – 04/11/2020 5
2. Danish Principles National EPC Data base • All data are being collected in one central data base • • • Data divided into three general groups • • • SBi – 04/11/2020 Danish Energy Agency manages the base Secretariat carries out quality control and suggest thresholds for allowing data into the base General data to identify building and EPC auditor Data for calculation of EP Results of certification and energy savings proposals 6
