Hello
Some technical additions (I’m not a professional, just transcribing this from the construction plan).
Facade 16 cm insulation Lambda 0.032 W/mK, hydrophobic base plaster, silicone-based facade plaster with 2mm grain size
Bisotherm 30 cm exterior wall
Not a low-energy house, i.e. no ventilation and no Blower Door test performed.
Regular shock ventilation (very meticulous)
Indoor climate feels very comfortable. (I have not installed a hygrometer)
New build from 2012
Today (2 degrees outside temperature at night, dry weather but heavy fog formation) I noticed two circular spots with a diameter of about 20 cm on the facade.
Spots like crop circles, i.e. nothing in the middle and the outer edge consists of small black dots that cannot be quickly removed.
Facade is in a light yellow tone.
What could this be?
Thank you very much in advance for the effort and answers
