Two new categories have been annouced for th ePassive House Institute’s building certification - in addition to the established Passive House Classic, there will also be the Passive House Plus and Passive House Premium classes.
The evaluation procedure for the new categories anticipates the energy transition and considers the building in an environment where only renewable energy is used.
The exact certification criteria and calculation details, according to the renewable primary energy (PER), system are available on passive housebuilding resource Passipedia.
Passive House Institute director Dr Wolfgang Feist said: “The demand of heating energy is greatly reduced in a passive house; therefore the consumption for hot water and domestic electricity is all the more significant. In the new evaluation, this is taken into account in a meaningful and future-oriented way”.
What the changes mean in practice will be further discussed at the International Passive House Conference taking place on 17-18 April in Leipzig.
At the conference, scientists from the Passive House Institute will demonstrate the implications of the new categories and the PER system for project planning using specific examples.
