Can we manage with one ventilation system, or do I need two?

How should we understand this question—what do you mean by “multiple ventilation systems”?
Kind regards

familieroettger23 Mar 2011 19:39I’m not sure what part of my question is unclear, but okay.
Do I need a separate ventilation system for the ground floor apartment and one for the apartment upstairs, or can both apartments be served by a single ventilation system?
Is that clearer?

Hello,
theoretically, one ventilation system is sufficient. However, since the ventilation intensity is usually adjustable with a 3-step switch, I think it’s better to have two systems. This way, the ventilation can be controlled separately for both apartments. Another advantage is the possibility to operate the systems with two separate electricity meters.

Hello,
No, the ventilation system always applies to a single usage unit (NE). One building, two apartments => two NEs => two systems!
This is regulated in the ventilation concept according to DIN 1946 for residential buildings to be planned. The reason is that a demand adjustment must be possible for each NE to ensure, among other things, the different ventilation levels according to DIN 1946-6.
If there is only one system for two NEs, this cannot be guaranteed due to the pneumatic connection.
The ventilation concept also determines the required air volumes according to DIN 1946 and DIN 18017. These are needed in the heating load calculation for sizing the heat generator.
Best regards
