The PassivHaus is super insulated, relatively airtight and very efficient. That means running costs will be low. It can be argued that PassivHaus sacrifices all other things on the altar of energy efficiency. Airtightness means mechanical heat-recovery ventilation is essential and that leads to a clean homogenous atmosphere Great article
