1/ I've been thinking about quality assurance (sad I know). The following thread presents what we know about dwellings:
2/ For ventilation provision - as assessed against Building Regulations - #Passivhaus provides much greater certainty.

4/ Occupied #Passivhaus dwellings, when factoring in uncertainty, perform as predicted.
Drawn from 2000 Passivhaus dwellings discussed in: link.springer.com/epdf/10.1007/s…
