The document discusses the Concerted Action EPBD IV, which aims to support implementation of the Energy Performance of Buildings Directive (EPBD) and maximize its outcomes. It notes the EPBD requires large amounts of data related to energy efficiency in buildings but could also deliver large datasets at low cost. In particular, energy performance certificates for buildings have great potential for data collection since over a million buildings are assessed annually across Europe. However, gaps remain around combining building data with energy use data and better connecting measured and calculated energy performance.

- 2. A new ConcertedAction EPBD IV Concerted Action EPBD IV: • Started 1 October 2015 and run until March 2018 • All EU Member States plus Norway • 29 partners – lead by DEA (DK) • 4 CA plenary meetings will be held • First meeting November 2015 in Copenhagen • Second meeting end of May 2016 in Vilnius • Third meeting will be in February 2017 in Valletta • Experts meet and share experience • Support implementation and maximise outcome of EPBD • Confidentiality in meetings – Free and open Lessons learned and share of best practice

- 10. Change in theCA The new structure reflects the following needs: • More holistic approach to buildings • More holistic policy packages – especially for existing buildings • Need for more focus on compliance and impact • => Need to improve data collection • More needs for policies for existing buildings • Need for more collaboration CAs and EE projects • Involvement of stakeholders
- 11. EPBD Policies • Implementationof EPBD policies request a large amount of data • But they could potentially also deliver very large amount of data at low costs
- 12. NZEB and CostOptimality • Some key elements in EPBD and European policy development are: • Nearly zero energy requirements for all buildings in 2020 and for public buildings in 2018 • Cost optimality as guidance for NZEBs both in new and existing buildings • Request very large sets of data !
- 13. Requirements New Buildings-nZEB Survey – filled in by half of MS shows that 60 % has defined nZEB standards by April 2015. Ways to calculate for instance RES are are very different ! Diversity !
- 14. Danish Building Codes kWhperm²peryear InDanish action plans for a CO2 neutral society it is the target that all building will be positive in the future (year still to be decided) Gross energy including heating, cooling, ventilation and hot sanitary water 0 20 40 60 80 100 120 140 160 Existing buildings .

- 16. Cost Optimality Large workhas been done on Cost Optimality – LCA’s Levels of LCA are are very different !
- 17. Cost Optimality Examples Goodexamples from Belgium and Denmark Diversity ! But all requests very larges sets of data
- 18. Control for NewBuildings Checking compliance and checking impact requires large amounts of data
- 19. Lack of consistentdata • In my past post we tried to check the true costs of these building codes • Wanting to compare the impact on real prices • But it was not possible to get consistent data for the same group of buildings: • On real savings • Nor on real additional costs • Special problems with energy and building physics • Metered versus calculated
- 20. Existing Buildings • Everyexisting building is different • Different construction • Different history • Improvements can bring them to different stages

- 23. Renovation Strategies Joint ResearchCentre, Renovation strategies Need for collaboration with EED Renovation was a large part of our last meeting in Vilnius: • Stakeholder meeting 30 May • Sessions on CA Plenary These strategies and implementation need to be based on very large sets of data
- 24. EPBD Policies • Implementationof EPBD policies request a large amount of data • But they could potentially also deliver very large amount of data at low costs • Especially the EPCs has a very large potential
- 25. Certification, EPC • EPBDrequires certification of buildings: • By construction • By sale • By rental • Regular for large public buildings • Every year 10.000’s or even 100.000’s of certificates are made in every European country
- 26. Certification, EPC Germany Diversity !Pros and Cons
- 27. Collection of Data •By most EPCs a consultant is sent to the house to collect a large set of data • In many countries these are collected in a central database • Cross Europe more than 1 million buildings checked every year !!! Could these only be made active !!!
- 28. Some Gaps Some gapsto be closed: • Better combination / connection between data on buildings and on energy use • Better data on results of change – before and after • Better connection between measured and calculated energy use • More data on consumer influence on consumption
