Building drying: Is it better to turn off the controlled residential ventilation system in summer?

Hello,
that doesn't make any sense at all in the current weather (daytime >20°C and at least 80% humidity).
The installed dehumidifiers dry the incoming outside air.

Best regards, Barossi

With construction dryers with dehumidification machines, you theoretically don't need to ventilate at all. You just empty the water daily (or depending on the size of the containers) and that's it. You can also do a proper burst ventilation if you want.
We didn't use construction dryers but set the windows to tilt after the initial setup. It worked wonderfully and caused no problems. It took 2 weeks longer for drying, but we had a 6 week rental buffer anyway.
Instead of €500 for drying, we spent €500 on rent. Overall, it was definitely safer ^^ Of course, it also depends on the season and how the building was constructed.
