 Just the right quantities of fresh air that are required for the good health and comfort of the occupants are supplied. Only untreated air enters the living areas, there is no recirculated air, thus providing a hygienic air quality.
-Ventilation can also take place if a simple exhaust air system and external air inlets are used.  The external air inlets let fresh (cold) air in the required amounts into the rooms.  However, for the Passive House the ventilation heat losses that would be caused by the disposal of the unused extract air would be much too high.  It would only be possible to adjust the energy balance with a high heating output.^
