Energy Conservation Ordinance 2014 – On the way to the nearly zero energy building / EnEV 2014 – auf dem Weg zum Niedrigstenergiegebäude

The tightening of the Energy Conservation Ordinance in 2016 provides the first step toward the introduction of nearly zero energy buildings. The level of performance for residential buildings after 2020 will most likely attain an energy quality close to the primary energy consumption of the KfW Efficiency House 55 today, at least regarding performance. The following report describes the requirements methodology of the Energy Conservation Ordinance 2014, including the KfW promotion, and provides calculation examples to clarify the issues.
