Above all: You don't have to change your life because of a ventilation system. Tilted windows... firstly, significantly less air exchange than with a ventilation system (especially noticeable in the morning after sleeping, a ventilation system simply does much, much more, preferably even CO2-regulated). In storms, in cold weather, no matter what, fresh pre-warmed air comes into the house. No cold drafts, no banging windows, no obligation to worry about it. You can still leave windows open wherever you want, it doesn't exclude that.

But OK, some people simply refuse any progress, that seems to be the true clash of civilization. "Back then" everything was just better.

Sure... the windows have to stay closed, instead a machine is installed that now does what every window can do, shoveling fresh air in. I call that artificial.

When the air "stands still" nothing shovels there. But hey, it's cheap so totally your thing...

Good question. After selling our single-family house and the maturity of the building savings contract, we honestly looked for an old house, but it had to be single-story. Otherwise, we could have kept the single-family house. That didn’t work here. The existing properties available here were either ridiculously expensive, or very old and worn out, or located in the middle of nowhere. So we changed our thinking and decided to buy the plot and talk to contractors to see what it costs to build new. And lo and behold, it isn’t a cent more expensive, except then the heating system isn’t already 10 to 20 years old, we get to choose the tiles, the kitchen is new, etc. The price for used properties here is simply totally distorted by Hamburg investors who want something by the sea. We are not building new because of any KfW stuff or because of a penchant for the latest technology. We see it quite prosaically: when we used 1000 euros for gas and 800 for electricity per year in the old house, we will hardly be able to reduce electricity consumption, the gas consumption in the new building maybe by 200 euros. All investments in expensive building technology therefore never pay off. You give the craftsman a few thousand euros and maybe achieve the last 10%, which amounts to around 160 euros a year.

And do you already have black spots on the facade above the window? Mold cultivation on the exterior facade - for those who have no other hobbies ...
