ᐅ Ventilation in Prefabricated Houses (Timber Frame with External Thermal Insulation Composite System) — Is It Also Needed in Solid Construction Homes?

GrymHello,
We have now visited quite a few model homes. We have looked at both prefabricated houses (timber frame with external thermal insulation composite system) and solid construction houses with an open mind. As far as we inquired, solid construction houses were always without a ventilation system, while prefabricated houses always had one.
In terms of indoor climate, we consistently preferred the solid construction houses, while I found the prefabricated houses somewhat “musty” (even though the ventilation system was on when asked). How can that be, or what causes this?
Has anyone built a solid construction house without external thermal insulation composite system (so monolithic) and without a ventilation system, and experienced problems with the indoor climate?
Has anyone had experience with a prefabricated house (timber frame with external thermal insulation composite system) without a ventilation system?

We currently live in a prefab house (built in 2008) with a mechanical ventilation system. At the moment, the ventilation is turned off, and when you enter the living room in the morning, there is a slightly musty smell—not damp or anything, but somewhat strange (possibly a bit like the smell of cardboard).
Our new house will be a solid construction without thermal insulation and without a mechanical ventilation system. However, we have decided to install a decentralized ventilation system in the wet rooms (2 bathrooms + utility room). I cannot say anything about the indoor climate yet, as we are still under construction.

Of course, you can ask.
Because the children and I struggle with dry indoor air in winter, and in summer the ventilation doesn’t help much since windows and doors are constantly open from people going in and out. In summer, ventilating through open windows at night and in the early morning hours is more effective than just using the ventilation system. I also noticed that the ventilation (level 1) stirs up more dust. So, the 12,000 euros we spent was basically wasted money, which we have now invested in other things. On top of that, there is the issue of unpleasant odors from outside when someone is burning something nearby or from the fields. I also have the impression that cooking smells spread throughout the house when the wind blows the wrong way. While in the kitchen, where the extractor fan is, you no longer smell anything, when you go to the children’s room, the cooking smell drifts in—not very pleasant.
However, the exhaust system in the bathroom is a great feature.

I’d rather tolerate an unpleasant odor overnight, which I can get rid of easily by airing out the room in the morning, than deal with dry noses and coughing children.
By the way, my husband turned the ventilation back on, and just two days later, I’m already struggling again with these problems: dry noses, a constant feeling of congestion, and one child has started coughing again. Coincidence? Probably not.
The "cardboard" smell mainly appears after warm nights—not every morning—and only in the living room. I don’t notice it in the hallway or bathroom.
