– the application of minimum requirements to the energy performance of new buildings and building units;
– national plans for increasing the number of nearly zero- energy buildings;
– energy certi cation of buildings or building units, and independent control systems for energy performance certi cates and inspection reports;
– regular inspection of heating and air-conditioning systems in buildings.
The Commission is to lay down a comparative methodology framework for calculating cost-optimal levels of minimum
energy performance requirements.
Member states should use this framework to compare the results with the minimum energy performance requirements which they have adopted. Should signi cant discrepancies – i.e., exceeding 15% – exist between the calculated cost-optimal levels of mini- mum energy performance requirements and the minimum energy performance requirements in force, member states should justify the difference or plan appropriate steps to reduce the discrepancy. The estimated economic life cycle of a building or building ele- ment should be determined by member states, taking into account current practices and experience in de ning typical economic life cycles.
Measures are needed to increase the number of buildings which not only ful l current minimum energy performance requirements, but are also more energy-ef cient, thereby reducing both energy consumption and carbon dioxide emissions.
For this purpose member states should draw up national plans

for increasing the number of nearly zero-energy buildings. Member states shall ensure that by 31 December 2020, all new
buildings are nearly zero-energy buildings; member states shall draw up national plans for increasing the number of nearly zero-
energy buildings.These national plans may include targets differ- entiated according to the category of building. ties to reduce emissions, rst and foremost through improvement of the energy performance of buildings. The Commission’s analysis shows that emissions in this area could be reduced by around 90% by 2050, a larger than average contribution over the long term.This underlines the importance of
achieving the objective of the recast Directive on the energy per- formance of buildings that new buildings built from 2021 onwards will have to be nearly zero-energy buildings.
This process has already started, with many member states imple-
menting stricter energy performance standards for buildings. On
4 February 2011 the European Council, taking account of the EU
headline target, decided that from 2012 onwards all member states
should include energy ef ciency standards in public procurement
for relevant public buildings and services.
Efforts will need to be strengthened signi cantly over time.Today, new buildings should be designed as intelligent low- or zero- energy buildings.The extra cost incurred can be recovered through fuel savings.
