1 NZEB IN EUROPE Different speeds on the road to an energy efficient building stock Maarten De Groote Buildings Performance Institute Europe

2 The Buildings Performance Institute Europe Committed to increasing the energy performance of buildings across Europe

3 Energy performance in buildings, a complex EU policy framework RES Directive 2009/28/EC Eco-design Directive 2009/125/EC Labeling Directive 2010/30/EU EPB Directive 2010/31/EU EE Directive 2012/27/EU Minimum RES levels in new buildings by 2015 Energyrelated products Minimum requirements Product regulations Energyrelated products Specific delegated acts Complement eco-design Buildings 9% energy savings by 2016 MS: Periodical NEEAP

4 European NZEB regulation: the EPB-directive (2010/31/EU) One EU requirement 28 national implementation rules!

5 Factsheet on NZEB definitions Ongoing EPBD revision

6 Different implementation and ambition levels Official definition Definition to be approved Definition under development Large variations on NZEB definitions 16 MS definition for new buildings 8 MS definition for existing buildings 8 MS share of RES explicitly stated (in others it is considered indirectly) Large range maximum primary energy (20-170kwh/m2) In FR, DK and B: requirements for the performance of the technical systems and to reduce the risk of overheating Cyprus Malta

7 NZEB transition in Flemish Region Improving average E-level paves the road for gradual sharpened requirements NZEB definition and gradual transition in legislation November 2013 NZEB is becoming well accepted 0% NZEB in 2006 to 7% in 2013 and rising 50% of future builders considers building NZEB 75% of early majority considers building NZEB

8 Moving towards nearly Zero-Energy Buildings

9 NZEB is a paradigm shift No more rocket-science, but Low-energy buildings are complex systems and need holistic approaches Integrated design methods, skills and financing Need for new business models in the construction sector Early adopters will gain, conservatives will lose

10 General concerns on NZEBs in Europe All MS will probably come up with an NZEB definition before 2020 Will late transposition give time to the building sector to adapt? DE, PL, Wallonia Questions on the level of ambition of the current NZEB definitions (AT, CZ) In some MS former targets were weakened (Malta, UK) The same nzeb definition for new and existing buildings (DK, LT, BG, CY, IT, LV) Poor compliance and control levels 50% of the Member States do not monitor the compliance of new buildings with the energy performance requirements!

11 Key challenges: the existing building stock 75-90% of the current building stock will remain in use in 2050

12 Renovations: lock-in effect and staged RENOVATION DEEP RENOVATION STAGED DEEP RENOVATION

13 Renovating Germany s Building Stock Germany has one of the most comprehensive financial support schemes in Europe for the improvement of energy performance of buildings Positive effects of financial support schemes on the economy, the creation of value and welfare Overall German renovation rate is at EU-average level (~ 1% p.a.) Building renovation needs to be increased, both in terms of rate and depth Model developed to generate Energy-Saving Cost Curves (ESCC) An Economic Appraisal from the Investors Perspective Focus on the cost effectiveness of different renovation measures in relation to a particular set of economic parameters Well geared towards understanding the economic motivation of investors 3 levels of renovations rate

14 German ESCC-project: 5 scenarios Based on permutations of economic factors: subsidies, energy costs, transaction costs, discount rates, learning curve, utility benefits Illustrate different policy measures that the government might apply to stimulate renovations

15 ESCC - Status Quo scenario

16 ESCC Best Case scenario

17 Key challenges: quality in (NZEB) buildings The better energy performance, the more important quality Consumers must be able to rely on expertise of building professional and get value for money Maximum lifetime Promised energy efficiency Healthy and safe building

18 Key innovations as game changers? Buildings interaction with the energy system Renewable energy production Demand Response Energy storage

19 Buildings interaction with the energy system

20 Enabling measures? Buildings interaction with the energy system Policy level: vision on the integration of DR, RES and storage in buildings Regulatory framework encouraging this buildings integration (EPB?) Aggregators supporting the different consumer groups Smart and user-adapted metering and control systems with a universal and open-source communication protocol Dynamic price signals for industrial, commercial and residential consumers

21 Key innovations as game changers? Internet of things leading to smart automation Source: BSRIA, 2015

22 Key innovations as game changers? Building automation and control technologies Building automation

23 Ongoing EPBD revision Stimulate higher and deeper energy renovation rates, with the necessary attention to technical and economic feasibility, health and comfort-issues A more effective policy landscape to address the problem of fuel poverty across the EU Legislation and support measures have to take into account the multiple benefits of better building performances Future buildings are energy efficient, smart and interacting with the energy market
