- | Anyone who has built or lives in a Passive House building already has this part of the energy transition taken care of. After all, the low energy demand in a Passive House can sustainably come from regional energy sources. The supply structure is transitioning from fossil sources to renewables at an encouragingly rapid pace. The conventional primary energy assessment systems for energy demand in buildings are based on old supply systems and do not work in the new one with an increasing share of renewables. The Passive House Institute therefore developed a new evaluation system based on renewable primary energy ([[basics: | + | Anyone who has built or lives in a Passive House building already has this part of the energy transition taken care of.

It is therefore a goal for the particularly ambitious: building owners and designers who want to go beyond what economic and ecological considerations already propose.

But heating energy demand does not tell the whole story; after all, heating energy demand is roughly equal to hot water demand in a Passive House. Demand for household electricity is usually much higher. A building’s total energy demand – including the energy needed to provide the building with final energy – therefore also needs to be taken into account. This is where the Passive House classes come into play. They divide buildings into classes or categories based on their total renewable primary energy demand and their renewable primary power production (Figure 1). | But heating energy demand does not tell the whole story; after all, heating energy demand is roughly equal to hot water demand in a Passive House.

We still have a gap to close before reaching Passive House Premium. Simply optimizing building services will not get us there; we have to make changes to the building envelope. Instead of the original window frames of efficiency class phB, Passive House windows of class phA can be used to reduce annual demand for heating energy down to only 8 kWh/ | We still have a gap to close before reaching Passive House Premium.
