4. European Level Definitions “ (…) 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.” Net Zero Energy Buildings - European Parliament Official Journal of the European Union July 2010 “(...) 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.” Nearly Zero-Energy Buildings - European Parliament Official Journal of the European Union June 2010 13 September 2010 Julien S.
