Energy efficiency of the Passive House Standard: Expectations confirmed by measurements in practice - report 2015

Authors: Søren Peper; Passive House Institute, Darmstadt; Wolfgang Feist, Institute for Structural Engineering and Material Sciences, University of Innsbruck

The measured values from more than 1800 apartments in buildings built to the Passive House Standard and ca. 170 apartments which were refurbished with Passive House components prove that the Passive House concept leads to extremely high heating energy savings in a practically verifiable and reproducible manner; these savings
amount to 90 % compared with the old building standard and about 80 % on average when compared with the legally stipulated requirements for new buildings. These savings have been proved through statistically significant empirical studies and have been confirmed in a large number of projects. The highest use-related individual consumption values of Passive House buildings are still far lower than the lowest consumption values in conventional new buildings.
