Hello.
We are currently planning the supply and exhaust air outlets for the (concrete) ceilings.
So far, the layout is as follows:
Basement: Exhaust air in all rooms except the storage cellar (currently no supply or exhaust air)
Ground floor: Dining/living/kitchen area (one open space) with both supply and exhaust air, office with supply air, bathroom with exhaust air
Top floor: Bedrooms and children's rooms with supply air, bathroom with exhaust air
A door gap of 5-8mm (0.2–0.3 inches) has been recommended for the room doors to avoid issues with air transfer.
Questions:
Are your ventilation concepts similar? Any experiences?
Does supply air work effectively only through air transfer under the door (in the basement, air would have to pass through the stairwell)?
What are your thoughts on the door gap (5mm (0.2 inches) seems common to me)?
Thanks in advance.

Alternatively, overflow via the door frame (search online; this must be made by the joiner/door manufacturer, but sound insulation ratings are not guaranteed), or "innoperform overflow seal" for the door (search online).
