Air intake in light well?

If

How is it then with the condensate? A slight slope towards the house, and there a drain with a trap?

If the slope is made towards the house, then use a dry trap inside the house. Otherwise, you will draw air from the room where the controlled residential ventilation is installed when the trap dries out.

Once again on the question of air intake:

It is said that it is best to intake on the north side to get cooler air in summer.
Ok, d'accord.

But in winter, that's rather counterproductive, right? I mean, if you intake on the south side, wouldn't you tend to save on heating costs?

And how bad exactly is it to intake on the south side?
From our location, we don't have much leeway to choose a different intake spot, except in the attic, but I'm afraid of hearing the system more at night there than when it's in the basement (I'm very sensitive about that) and I want to convert the attic later, so having such a device there wouldn't be ideal.

You only hear the system at full throttle, which you normally don't use. And counterproductive? It's about angles that you won't notice later - don't let something like that drive you crazy - and something like that should be planned by someone who knows what they're doing anyway. Or do you really think that the AIR temperature differs by 10 degrees between the two sides?

No, but I haven't been able to figure out how much that actually makes a difference. So you mean, if I suck in through light wells on the southwest side and blow out around the corner on the southeast side, that's not really a problem? It would be nicer the other way, but does it also work like this? The general contractor suggested exactly that or alternatively both on the southeast side with a distance of 3m (which is then relatively next to the front door, but inside the shaft). I'm wondering right now: what happens if water gets in there? The other light wells are installed as pressure-water-tight without drainage, also with the note that drainages often clog over time. If the controlled residential ventilation would now draw in water, that wouldn't be so cool. And what if the shaft gets covered with snow at night? Would the controlled residential ventilation and possibly the air-water heat pump no longer work?

Well, those are just the problems I see with an intake in the basement without towers - we also have that problem with the chimney fresh air.

Besides, I would never intake near the ground - partly because of radon (if present) and more because of dust.

and certainly not at the front door, because you will hear that.

therefore, the placement in the basement is generally rather unfavorable...
