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

Hello,
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?

@chaosandi : Why?This has something to do with pressure. Just try searching for it online.
Sorry, but I don’t want to copy something in here myself right now. I can’t explain it in my own words ops:
Since the mechanical ventilation system, the exhaust hood, and the fireplace extract or consume indoor air, this creates a negative pressure indoors.
However, this can be avoided by designing the wood stove to be room-air independent. This must be planned during construction. The chimney will include a ventilation duct.
An external air supply must also be ensured during the operation of the exhaust hood. This can be provided either by a window switch or an automatically opening vent in the external wall.

We really wanted to have an exhaust hood. It was already planned. However, the heating technician advised us several times against it due to the airtight building envelope and so on. Hopefully, it was the right decision, and we chose a good recirculating hood.

@chaosandi: Why? Why did I decide against a wood stove?
Because I don’t want it just as a decoration. Otherwise, I might as well install a TV in the wall and play a fireplace DVD.
But since we spent our holiday in underwear whenever the stove was on (which isn’t necessarily a bad thing ), I decided against it. The stove only took CO2 from the air and made me tired. Plus, the house was too well insulated anyway, and in my case, it will become even more so.

A properly sized stove will not overheat the house.
Also, most stoves in new builds are designed as room-air independent combustion units, so the stove neither “steals” your O2 nor releases CO2 (which is rather unhealthy) into the room...
