5 EU-Directive for Nearly Zero Energy Buildings Directive 2010/31/EU: of the European Parliament and of the Council of 19 May 2010 on the energy performance of buildings: Nearly zero-energy building: a building that has a very high energy performance. 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.
6 EU-Directive Nearly Zero Energy Buildings Germany = Europe aims to construct and refurbish due to EU- Directive 2010/31/EU and consecutive national laws (EnEV 2014) Nearly Zero Energy Buildings. Measures: Highest efficiency by strong insulation and heat recovery Solar energy generation at the building skin Use of environmental energy by heat pumps Life Cycle -analysis of used materials (DGNB) Construction and operation contracts for huge public buildings for about years to allow investment in renewable energy and efficiency
