Key findings for 2014
C1: Market penetration of nZEB
- ZEBRA average: 0.32
- nZEB had a share of 1/3 on the reported new constructed ZEBRA floor area. The result is very much affected by the figures for France. In France, nZEB became standard in 2013. France contains about 28 % of the ZEBRA floor area reported for 2014. The nZEB share in most other ZEBRA countries is below 10 %.
- The share is likely to increase with the further integration of nZEB in national building codes.
C3: National policies supporting the market development for nZEB
- ZEBRA average: 0.52
- Seven policy categories have been assessed regarding their sufficiency to stimulate the development of residential and non-residential nZEBs: Relevant regulations; Relevant economic incentives and financing instruments, Energy performance certificates use and layout in relation to nZEB standard, Supervision (energy advice and audits), Information (tools), Demonstration, Education and Training.
- In 2014, Policies addressing the seven categories were in place in most of the ZEBRA countries.
- Policies appeared to be most sufficient in UK (score of 0.76) followed by Austria (0.71) and Denmark (0.71).
- Slovakia was the country that addressed the categories least (only 3 of 7 categories were addressed) followed by Sweden and Portugal (each 4/7).
- Confidence in policies was least in Spain (score of 0.24), Portugal and Slovakia (both 0.29).
- “Education and training” is the category that in average achieved the weakest rating in the assessed countries.
- Policies become more and more effective and concrete regarding nZEB requirements. Still not every country implemented nZEB as national building standard.
C4: National progress towards cost-optimal building performance requirements
- ZEBRA average: 0.94
- Building codes in place match (3) or exceed (6) cost optimal energy performance levels in 9 out of 18 ZEBRA countries.
- The Netherlands and Poland did not report cost optimal levels so far.
C6: Availability of nZEB-relevant components
- ZEBRA average: 0.83
- nZEB components are well available in most participating countries. Differences occur primarily due to varying construction behaviour resulting from cultural or climatic background.
C8: Level of nZEB-relevant expertise of actors
- ZEBRA average: 0.63
- Only in 2 out of 16 countries, experts think that professionals can cover future demand for nZEB construction/renovation, the majority of experts in the other ZEBRA countries is sceptical.
C9: Level of awareness / information / acceptance in the society
- ZEBRA average: 0.94
- The awareness for energy performance of buildings is rising all over Europe. However, this criterion shall be treated with caution as it has not been assessed before 2014.
C10: Dependency of property value/rent on the energy performance
- ZEBRA average: 0.74
- Energy performance of buildings still has minor impact on customers’ decision to buy/rent a real estate, compared to other aspects like location, price and size of the real estate.
Resulting Maturity of the EU nZEB market
- ZEBRA average: 0.66
- Though market conditions appear to improve throughout the EU, nZEB are still rare in most EU member states. Even if their share is expected to increase over the next years, supporting policies (e.g. financing instruments, energy performance certificates, energy audits) and the expertise of building professionals are crucial for a successful nZEB market development. Harmonised nZEB standards on European level and periodic nZEB market status updates would enhance this development.
