Alex, if it turns out like that, thank God we built our house when we did. Living in a plastic bag with styrofoam insulation—terrible. The windows are probably screwed shut, and if the mechanical ventilation system fails, you suffocate. Your eyes constantly itch and everyone gets asthma because of the dry air.
No way. The EU? Seriously? Poland, Greece, and Slovakia are going along with this nonsense? I just can’t believe it. Karsten

Hey, even though it’s a buzzword, it is an "unconscious bias." Becoming aware of it is not easy, but it is possible. However, the willingness to do so must be there.

Why are we talking about mechanical ventilation with heat recovery? Because it is a key component of modern houses, and specifically the problem expressed by the term "plastic bag" is not only eliminated but the situation is improved many times over compared to houses built in earlier years.

Well, opening and closing windows is something anyone with a basic education can understand, but controlling a system like this requires a certain liking for it.

A tutorial just for you. What is necessary to operate a mechanical ventilation with heat recovery system:

And depending on the level of contamination, every 6–12 months:

Why use boarded-up windows in a passive house?

I would like to know which building materials are used for interior construction and furnishings by those who object to plastic or foam insulation on the exterior facade.

Regarding the requirements that must be met, they will likely become stricter in the future. Whether costs will increase if everyone has to build this way remains uncertain. Our shell passive house was more expensive than a KFW 55 standard, but the building services were cheaper, since we did not install underfloor heating. Overall, the difference was not significant.

How the construction boom, interest rate trends, skilled labor shortages, and scarcity of building land will affect the market remains to be seen.

There is a lot of construction happening currently in the Hannover region. Perhaps in 3-6 years, some nearly new houses will be available on the real estate market at reasonable prices.

That’s true, I hadn’t thought of it that way before. Condemning plastic on the exterior insulation system while overlooking the plastic inside—such as in the flooring or impact sound insulation—or outfitting the interior with CPL doors or furniture from IKEA and similar stores.

To be clear: I have no issue with CPL or IKEA, nor with exterior insulation systems—even those using polystyrene. [emoji6]

Complete product range from Sto for inhalation, unobstructed view through the plastic window, and a rum and cola mixed from the PET bottle. As I said, bias is clearly at play.
Completely subjective, purely a matter of opinion.

Hello,
until now I have only been a reader and observer.
The pros and cons of mechanical ventilation with heat recovery versus natural window ventilation are well known and can easily be found online.
In discussions about mechanical ventilation with heat recovery, it becomes clear that those who have installed or chosen it tend to look for (and want to hear) arguments in favor, while those who have not chosen it look for arguments against (or do not want to listen).
Since almost everyone seems satisfied with their decision, either the right choice was made or people are not brave enough to accept the truth.
