About passive houses and plastic bags and styrofoam fur

It's just not...

Too dry air? Enthalpy heat exchangers, problem solved. For example, we have a constant 45%. And I could still vary it here if I want... (We don't have ETICS, but that doesn't change the indoor climate since the same requirements for airtightness apply).

Damage to facades? You have it on all facades. That you think it occurs more often on ETICS systems is subjective. Fraunhofer claims the opposite and says aerated concrete facades have more damage due to a significantly higher number of thermal bridges.

Regarding traffic, I completely agree with you! ETICS facades have an extremely good CO2 balance over their lifetime... From an ecological perspective, definitely sensible to insulate... That can't be an argument against it.

I agree with you on all points! Out of interest: how do you manage moisture recovery with an enthalpy heat exchanger? That only works in principle with rotary heat exchangers by varying the rotation speed. Enthalpy heat exchangers use a membrane in the plate heat exchanger, where you cannot intervene.

Nordlys I invite you to my place. Well insulated without Styrofoam in the walls. Several allergy sufferers feel comfortable with us.

You are right. Exclusively through the amount of air that I drive through the system. I currently have the ventilation set quite high, the humidity increases further when I reduce the power. But for me personally, this is now a pretty ideal value that I have.

You are, like others here, probably someone who enjoys engaging with technology. I am not like that. That's why I have always been an Apple fan; they never demanded that I know how to use computers, you just have to be able to press icons and it worked.
The same goes for opening and closing windows, anyone with a woodworker’s high school diploma can understand that, operating such a system, you have to like it.
It can't be the ultimate wisdom to equip a building with technology that makes it habitable only through that technology. But, I think here not only views but entire life attitudes collide. Karsten

How do you regulate the moisture recovery with an enthalpy heat exchanger? That only basically works with rotary heat exchangers by varying the rotation speed. Enthalpy heat exchangers use a membrane in plate heat exchangers, where you cannot intervene.

I agree with Nordlys again

Humans are analog creatures with analog lungs and ideally also open analog windows for ventilation in the traditional way by using a handle with their front paws.

Houses are not built for houses, but for their inhabitants. And they have souls, who may have difficulty with the idea of getting their climate "digitally simulated," if I may put it that way. The mind may rightly say that chemically it is perfectly equivalent. But that also applies to astronaut food. To appropriate human living, for me, also means being allowed to have the "quirk" to live analog.

And no, even if there is global warming: I am not to blame. And sticking reprocessed petrochemical waste on my house is not the solution either.
