on the energy performance of buildings

(recast)

Article 9

Nearly zero-energy buildings

1. Member States shall ensure that:

(a) by 31 December 2020, all new buildings are nearly zero- energy buildings;

and

(b) after 31 December 2018, new buildings occupied and owned by public

authorities 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 differentiated

according to the category of building.

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;
