Passive House Institute in Germany has established new categories for building certification that take into account a building’s primary energy system. The established standard will be called Passive House Classic, while the new categories are Passive House Plus and Passive House Premium.
With the introduction of the new categories, the overall demand for renewable primary energy (Primary Energy Renewable) will be used instead of the primary energy demand, which was previously used. The exact certification criteria and calculation details according to the renewable primary energy (PER) system are available on the online resource Passipedia.
