Would it be possible for someone to take another look at my existing ventilation system design?
Since this is a renovation of an existing building, the placement of the vents is unfortunately quite limited.
Project information:
Built in 1961
Two people (no children)
In the office (ground floor), usually two people are present most of the time


Ground floor:
There is no door between the living room and kitchen/dining area, but a 170cm (67 inches) wide open wall space.
Between the kitchen and hallway, there is a 100cm (39 inches) wide sliding door.
Between the dining area and pantry, there is an approximately 80cm (31 inches) wide sliding door.
The pantry is unheated (but indirectly warmed by the heating manifold).
Upper floor:
All supply and exhaust air vents will be installed in the ceiling (here I can partly run the ducts through the ribbed concrete slab).
The ventilation unit is located in the basement.
On the ground and upper floors, I will create some ventilation openings in the walls, which are marked in violet:
Upper floor: between bathroom (WC area) and hallway (possibly also bedroom to hallway)
Ground floor: above the office door to the hallway and pantry to hallway
I am sure I have forgotten many points to describe.
If anything is unclear, please ask directly.
