Energy Performance of Buildings Directive
– Sets framework for minimum performance requirements for new buildings and major renovations
– Cost Optimality – Nearly Zero Energy Buildings

FINDINGS: PRACTICAL IMPLEMENTATION OF NATIONAL PATHWAYS TO NZEB
Brussels established a nZEB definition in 2011 and enforced nZEB requirements in 2015
Some countries established measures to deliver a gradual transition towards nZEB levels:
FINDINGS: PROGRESSES SINCE 2013 To date, a nZEB definition for new buildings is available in 15 countries (plus Brussels Capital Region and Flanders), while in 2013 there were only 4 official definitions.
Only 8 countries have already formally established nZEB requirements for existing buildings.
FINDINGS: WIDELY DIFFERENT SITUATIONS
Cyprus Malta
Official definition Definition to be approved Definition under development
Quantity and quality of nZEB requirements differ considerably: - the maximum primary energy
consumptions show a large variation of a factor 4 to 5.
- In 8 countries the share of RES is explicitly stated, in other is considered indirectly.
- Often a limit on the final energy required for space heating is established.
In a few cases (e.g. in France, Denmark and Belgium) requirements are established for the
performance of the technical systems (e.g. heating and ventilation units) and to reduce the risk of overheating of the building.
New build nZEB levels (residential)
Country kWh/m2/a Primary Energy Energy uses included RES requirement
Denmark 20 HVAC, DHW 51% - 56%
Belgium (Flanders) 30 HVAC, DHW, auxiliary systems >10 kWh/m²y
Slovakia 32 Heating, DHW 50%
Belgium (Brussels) 45 Heating, DHW, appliances -
France 50 HVAC, DHW, lighting, auxiliary systems -
Estonia 50 HVAC, DHW, lighting, HVAC auxiliary, appliances -
Cyprus 180 Heating, cooling, DHW, lighting 25%

Is it time to be more prescriptive about what constitutes nZEB – both new build and renovation?
