ᐅ Controlled residential ventilation: Is an air gap under the doors necessary?

Hello everyone,
we are building with a central controlled ventilation system for the living spaces. I have heard several times that the interior doors need to be trimmed by about 1 cm (0.4 inches) after installation to allow sufficient air circulation.
Is this true? And if the doors are trimmed, the bottom edge will be “open,” without any coating or edge banding. Is that not a problem?
How is it handled in your experience?

By the way, I’ve already talked to our heating technician, and he said that apart from the “normal” air gap under the door, no special ventilation slots or gaps are needed due to the controlled residential ventilation system. Well, that’s how it goes with housebuilding. I recently visited a regional building exhibition and my assumptions were completely challenged. All four ventilation system providers I asked insisted that the gap under the door is necessary (alternatives being leaving the door open or installing a grille in the door). Somehow, the air has to flow through. None of them suggested frame ventilation, special drop-down seals, or overflow vents, even though I made it clear that I didn’t want any gap under the door.WildThing schrieb:
The ventilation system was designed and the airflow calculated by the manufacturer, so it should be fine from that perspective. The manufacturer will base their calculations on the assumption that air can flow freely. It is the builder’s responsibility to ensure proper air transfer on-site. So that doesn’t really help you.At minimum, I would expect the ventilation specialist to a) ask what volume of air needs to be transferred, b) ask the door width, and then c) look up the required gap in their design table (which would be based on industry standards, for example DIN, although acoustically that’s not ideal).
It would be better if they proposed alternative solutions that don’t let in excessive light or noise.
What’s especially frustrating is that this topic has been openly discussed online (in German) for at least 10 years.

But I can’t find a single experience report… We have one. It works (that’s really all I can say).
