But that it also works without controlled residential ventilation is out of the question. There are other ways to ventilate. But DEFINITELY not THROUGH THE WALLS!!!
But a central controlled residential ventilation system that exchanges, filters, and, for all I care, aromatizes the air in all rooms, I consider superfluous for our construction project...
Certainly, the costs are relative, but these days you quickly lose the warranty if you don’t conclude a maintenance contract! So I do think that if you pay attention to building physics, you can get along quite well in a building without controlled residential ventilation.
Warranty only with a maintenance contract??? That’s not the case, at least not with controlled residential ventilation. Pay attention to building physics! Yes, but then you have to be home regularly (even at night) to ventilate the house properly. That only works without vacation and if a partner is always home to open the windows. At the moment, when we wake up in the morning, the bedroom smells like a puma cage and moisture has settled on the windows (two adults and a toddler in the 40 sqm bedroom). Over time, the window frames rot quite a bit (you can clean it, but it’s not nice) – our current house is only 9 years old and properly built (according to the 2004 standard).

Aromatizes? I’ve never heard of that...
Of course, it also works without controlled residential ventilation. But then you have to ventilate differently. For example, by manual window ventilation or window rebate ventilation, etc. etc.
Because your walls actually do the opposite of what you assume!
Controlled residential ventilation is mainly just comfortable.
