Floor plan planning shortly before submitting the building application

It looks silly at the front facing the street if an exhaust vent is installed there, but it's definitely better than the pipe.

Oh, come on. A 20x20 grid at lintel height is hardly noticeable.

Under what circumstances could such pipes be installed upwards in the exterior wall? This has always been categorically ruled out so far.

Does the Energy Saving Ordinance prevent Poroton from being used for pipe routing at all? We do not have a kfw house. Or are there calculations for this?

What speaks against alternatively discharging via the garage? That would be a new approach.

For something as trivial as a tracheotomy for a toilet, I would not, for the life of me, hold a competition to reinvent the wheel.

Just have the pipe bend before passing through the ceiling into the outer wall, and that's that. No special treatment, no fancy footwork.

Just have the pipe bent before the ceiling passage through the exterior wall and that's it. No special treatment, no dancing around.

I have to ask again exactly why they didn’t want to do that. They always treated the exterior walls like a sacred cow that no one was allowed to touch. That solution would also be my favorite.

You probably remember this from discussions about pipes running through the exterior wall. However, this is about a tiny penetration.
