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.

In our building, the same number of supply air and exhaust air vents are planned on each floor. This is to avoid overpressure, underpressure, or strong drafts inside the house.
Supply air is usually provided in living and sleeping areas. Exhaust air is extracted from the kitchen, bathrooms, laundry room, etc.
I also consider supply air important in the basement, as it helps with drying laundry. Additionally, it prevents stored items in the basement, such as documents and clothing, from developing musty odors.

We have Zehnder.
Ground floor
Kitchen, WC, utility room – exhaust air
Living room – 2x supply air
Upper floor
Bathroom, office/dressing room – exhaust air
2 kids’ rooms, bedroom – supply air
The planning was done by a professional company.
Minimum door gap 8mm (0.3 inches)
The exhaust air from the utility room and dressing room has been restricted to allow more air to be extracted from the other wet rooms.

Supply air, ground floor: 2x living room, office
Exhaust air, ground floor: kitchen, bathroom
Supply air, upper floor: children's room 1, children's room 2, bedroom, dressing room
Exhaust air, upper floor: bathroom
Additionally, there is a valve installed in the exhaust duct in the utility room in the basement, so air is also extracted there.

Opinions on the floor gap (5mm (0.2 inches) seems normal to me)? It is also possible without a floor gap (forum search, otherwise ask again).
