From December 31st 2020 on, all new buildings are to be built “nearly zero-energy”, but for public buildings for which the directive sets the date of December 31st 2018.
Article 9, Directive 2010/31/UE of the European Parliament and of the Council of May 2010 on the energy performance of buildings.
“The main goal towards energy saving stands for reducing energy consumption at every possible level”
‘Nearly zero-energy building’ (NZEB)
Reduction in energy consumption and the use of energy from renewable sources in the building sector are a significant part of the measures required to reduce European Union energy dependency and the emissions causing greenhouse effect.
‘Nearly zero-energy building’ is a concept on energy consumption presented by the Directive 2010/31/UE, where it is stated that:
‘Nearly zero-energy building’ means a building that has a very high energy performance, as determined in accordance with Annex I. The nearly zero or very low amount of energy required should be covered to a very significant extent by energy from renewable sources, including energy from renewable sources produced on-site or nearby.
Nevertheless, European Union countries are to define by their own the ‘Nearly zero-energy building’ concept. Spain will also have to develop its own definition for the different periods set: by 2015, by 2018 and by 2020. Afterwards, the Commission will assess the national plans.
