A new building was recently described in a newspaper where the air exchange is regulated through window rebate ventilation.
Is this a reasonable alternative to a controlled ventilation system, and does it help prevent mold?
How exactly does it work?

Yes, that sounds contradictory. But you have to do something to prevent mold growth. And opinions on ventilation systems are very divided. With airing out by opening the windows, warm air also escapes.No, there is no divided opinion on this. Or is there really someone out there who says something negative about a central mechanical ventilation system with heat recovery?

He writes here: https://www.hausbau-forum.de/threads/was-wurde-unerwartet-gut.32287/page-4#post-346013 and https://www.hausbau-forum.de/threads/160m2-efh-in-Holzständerbauweise-am-nordhang-mit-Keller.28614/page-9#post-279190 – that’s me again, of course

Probably only the cost factor was meant. How much does a window frame ventilation system cost per window? What extra cost could there possibly be for drafty windows?
In older buildings: "The windows are drafty and should be replaced." "Oh, nonsense, that’s state-of-the-art window frame ventilation technology."
Edit: I’ll just add that this is mostly irony, before anyone here starts hyperventilating or having heart attacks.
