Attached you will find two images: one shows the drainage layout proposed by our civil engineer, and the other is from our gas and water installer. The civil engineer suggests two vent pipes going through the roof because he believes this will prevent potential problems. I personally prefer the solution from the installer, which uses only one roof vent. If I interpret DIN 1986-100 correctly, there is nothing that opposes this.
What are your thoughts? Is there any technical reason this could cause issues?
As you can see in the photos, these are the two versions!
Thank you very much for your help

By the way, these are more ventilation vents rather than exhaust vents (but actually both). Without air supply into the pipe, wastewater does not flow due to the resulting negative pressure. In one of the variants, I don’t see the stack ventilated at all? That would not be acceptable. An internal vent is optionally possible here as well, but if it can be avoided, I would never do it. It’s better to bite the bullet once and pay the few extra dollars for the roof-vented ventilation. This way, wastewater flows more smoothly through the pipe.
In option 2, the bathroom on the first floor shares the drainage system with the ground floor, and the ventilation is routed through the roof at the first-floor bathroom.
I’m not sure if it’s a good idea to have the only ventilation "behind" a soil pipe. The architect’s option is the safer choice.
