ᐅ Drying out a newly constructed house (whole building)? (Dehumidifiers)

The liquid screed has now been in the house for about 6 weeks.

Since shortly after that, the underfloor heating has been running constantly.

For about a week now, two dehumidifiers have also been running in the basement: a large one in the utility room and a smaller one alternating between the office and the guest room.

I am not sure whether the basement windows should be open, closed, or tilted.

When the basement windows are closed, we have about 35% humidity at around 28°C (82°F).

Yesterday, I aired out the basement briefly by opening the windows wide, and afterwards the humidity rose to about 60%.

How can I achieve the best result?

Thanks and best regards!

Windows open ... Warm air can hold more moisture than cold air ... (a dehumidifier is also more effective with warm air) ... The ideal relative humidity is between 40% and 60%

When using dehumidifiers, windows must remain closed at all times. The rise in relative humidity occurs due to the temperature drop after airing (ventilating).

Good evening,

It wouldn’t be so bad if you would at least disclose your qualification for the above statement in your profile….

So, the statement is understandable to everyone through basic physics and can be verified within about 2 minutes if necessary.

Hello,

That might be true for you and a few other users. However, I strongly doubt that every reader or contributor here can verify it as well. And if the user trusts the statement blindly (since the internet is always right), I want to be assured that there is a professional behind "Fassadendoc," or at least an experienced builder.
