Yes and No:
There is in article 2 of the EPBD Recast (Directive 2010/31/2U) a European definition of 'nearly zero-energy buildings:
‘nearly zero-energy building’ (NZEB) 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.
As part of the transposition of the EPBD Recast into national legislation, each country is adopting a national definition of NZEB. In practice, it means that there are substantial differences between the NZEB definitions (in calculation method as well as in type and level of requirements).
