Definition nZEB per country

A definition for nearly zero-energy buildings (nZEB) was essential for the further operation in the COHERENO project. Official definitions did not exist in all project partner countries at the beginning of the project in 2013. For this reason the project partners presented either the official existing nZEB definitions or the nZEB definition developed solely for the COHERENO project.

Based on the nZEB definitions presented below the partners were looking for examples of highly efficient refurbished houses in their countries and for participating companies, planners, policy makers and financiers who have experiences in this sector of buildings.

The guidelines for the definitions are preset by Interner Link  international agreements, especially the Externer Link  European directive 2010/31/EU (Energy Performance of Buildings Directive, EPBD). In EPBD 2010/31/EU, article 2, 2 it is written: "‘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".
