And this is with buildings designed to meet
the passivhaus standard benchmarks and modelled in the passive house planning package, not just designed to some notional «passivhaus principles».
Buildings notionally designed to meet
the passivhaus standard benchmarks, but not certified, do not.
It is quite possible to use only as much energy as
the Passivhaus Standard benchmark in a building of a much lower standard.
