Proper drying / tilting the window?

Well, are you searching again?

How do you come to the narrow conclusion that the air exchange rates are higher? What about drafts? What about rain? What about gusts of wind? What about cold? What about even air distribution?

By the way, exhaust air filters are also installed as standard...

Oh, you will surely say something clever again. But clear sentences would be better - the last sentence is really hard to read.

If you have a problem, then write me a PM and please keep it out of the forums. And becoming aggressive, bordering on insults, do you really need that? Does that belong in this nice forum? Spelling or grammar mistakes that I occasionally make with my phone, you can keep them if you find them first. Instead, find out how high the air exchange rate of a [Kontrollierte-Wohnraumlüftung] is and compare that with typical values of windows! You will be amazed at how high the rate of tilted windows is! That shows that the air movement of a [Kontrollierte-Wohnraumlüftung] is nowhere near enough for drying (you can also calculate this if you don’t believe it). It’s not about the exhaust filters of the [Kontrollierte-Wohnraumlüftung] in the device, but about those in the valves so that the pipes don’t get filthy; and these are by no means installed as standard. Moreover, at almost 100% humidity, there is an enormous risk of condensate that could potentially accumulate somewhere in a pipe bend. Therefore, I think [Kontrollierte-Wohnraumlüftung] is out of the question. The window not being an option due to rain, for example, we have also had. That’s why I agree with the proposal of using a dehumidifier.

Reasonably planned controlled residential ventilation systems also have filters on the exhaust vents - I know what I'm talking about.

And funny, two colleagues of mine carried out screed drying at a low level with it - no problems at all, humidity around 60 percent, but you as a theorist will surely be right...

By the way, stronger pipe bends are also not present in a properly executed installation. But you are welcome to explain to me why condensate formation in the exhaust duct is harmful. Apart from the permanent ventilation that dries, where exactly is the problem?

Near an insult? Vivid imagination - honestly. I could not decipher your sentence. If I were mocking you, it would look different...

But back to the subject - we are talking about a building that already has a functioning heating system. A tilt window ventilation has no place there...

If a controlled residential ventilation system is available, one should rather try to use it as a construction dryer with appropriate measures - costs less, works throughout the whole house simultaneously.

I know that too (just as well as you probably), interesting how a layperson can have such different experiences! I know many people who have retrofitted it themselves. There are still many manufacturers who do not offer that (including well-known ones!), but most vents can be equipped with filter pockets by yourself. Even large and expensive prefab house companies from my building area did not have exhaust air filters on the vents. Otherwise, I just say: What works in individual cases somewhere should not be generalized and given as good advice to others, but rather differentiated and communicated that way. Imagine the said builder has a controlled residential ventilation system with moisture recovery (and no clue about it because he is not familiar or interested!). And with that, he then dries his building... Otherwise, the speed and amount with which industrial dryers properly dry is incomparable to a controlled residential ventilation system on a low setting as you suggested.

And you really think that moisture recovery wants to raise the humidity back to tropical levels? Well, anyway... the OP has now received quite a few tips.

The recovery has no will, but if it only delivers 80% efficiency, drying...well...takes a bit longer :x
