Question for the professionals:
-New construction KfW55
-Central ventilation system
The specialist company only kept a 2-meter distance between the exhaust air and the fresh air, and that in a line one above the other. (see pictures) Fresh air on top, exhaust air below.
The whole setup is on the west side. Now I and several other craftsmen have concerns that an air shortcut could occur.
The specialist company has no concerns at all and sees no other option (due to dew points, etc.).
Unfortunately, the sanitary company did not consider this issue properly during the shell construction planning.
Maybe someone still has an alternative possibility/idea?
Or perhaps no concerns because they have installed it like this several times before?
Ideas for underground installation were rejected due to condensate (opinion of the specialist company).
Also, the idea to place it on the other side of the outside door (which would also be only about 2 meters apart).
Our technical room is very cramped, the west side is the only exterior wall.
Do you need any further information?
Please share your opinion/advice or solution!
