The Passive House Classes Classic, Plus or Premium can be achieved depending on the use of renewable energy sources.

EnerPHit Classic, Plus und Premium

EnerPHit is the established Standard for refurbishment of existing buildings using Passive House components. Despite the slightly higher energy demand, it offers virtually all the advantages of the Passive House Standard.
