In May 2010 the Directive from December 2002 has been revised by the European Commission and defines general requirements on the energy performance of building in the European Union:

It promotes minimum requirements to the energy performance within the European Union, which will be revised later than every 5 years. All elements of the building are concerned (f. ex. heating, lighting, cooling, ventilation, hot water, etc.).
All new buildings occupied and owned by public authorities should be nearly zero-energy by 2019, with all other buildings by 2021.
As of 2013 and every 3 years thereafter the Commission shall publish a report on the progress of Member States in increasing the number of nearly zero-energy buildings.

Financial incentives"Member States shall draw up, by 30 June 2011, a list of existing and, if appropriate, proposed measures and instruments including those of a financial nature, other than those required by this Directive, which promote the objectives of this Directive".
"The Commission shall, where appropriate, assist upon request Member States in setting up national or regional financial support programmes with the aim of increasing energy efficiency in buildings...."

Energy performance certificates
In the future all member states shall establish a system of certification of the energy performance of buildings. The validity shall not exceed 10 years.
