EU Parliament: All new buildings zero energy from 2019

Already on April 23, 2009 the European Parliament voted in favour of a bill which states that from 2019 (12-31-2018) all new buildings have to be zero energy ("where, as a result of the very high level of energy efficiency of the building, the overall annual primary energy consumption is equal to or less than the energy production from renewable energy sources on site" Source: http://www.europarl.europa.eu).

This plan is supposed to be achieved by:

Member states are not only supposed to adjust national legislation to this decision but also to further encourage the upgrading of energy efficiency of existing buildings. 

Public statements to this law have been minor and only few are aware of its existence. To what extent it is feasible or not is highly controversial especially when considering the varying levels of development among EU member states.
