Is centralized controlled ventilation common in the kitchen area?

Hello to the collective intelligence,

We are currently planning the central controlled residential ventilation. The living area has an L shape. The kitchen exhaust is recirculated air, we do not have a chimney. In the living area, supply air vents are planned in three corners.

Now my question: In the first planning version by the general contractor, no exhaust air vent for the controlled residential ventilation is planned in the kitchen area or the entire living area. I thought exhaust air was standard in wet rooms and kitchens according to recognized rules of technology? Before I follow up on this, I wanted to ask for your assessment.

Thank you very much, Jürgen

yes, the exhaust air belongs in the kitchen.

Thank you very much. Then I will have it incorporated.

45 m³/h are required for bathroom, kitchen.

45 m³/h are the regulation for bathroom, kitchen.

Out of curiosity: which regulation refers to what?

My BT also has no exhaust in the kitchen, but in the adjacent toilet...

Hello,

is it stated in DIN 1946-6 Residential Ventilation DIN.
