Ventilation system - Noise level dependent on which factors?

And yet you don’t want to show the forum any approaches to qualified help just because the favorite hasn’t released the floor plans yet? – especially with Pfeifenkopf or Alpine plots, you can get further with many co-thinkers!

The plot isn’t going anywhere and the questions about it aren’t getting any fewer ;). The priority in the first moves was to pay attention to how the house builders handle the plot and how they assess the location. Those who have already shown no interest here and dismissed it as if it were the usual, who dramatically underestimated the additional building costs, or those who dismissed us, have been kicked out. You will still get to enjoy advising me on the plot, probably more than you like. I have to divide my time until signing, so the plot takes a back seat for now, until the more important questions are asked and answered. The question about the meaningfulness of asking my questions on this to the co-thinkers doesn’t really arise. That’s why I am here and again need your help on this topic…

Sure, it works with an air pump, why not? But for 24 degrees/365 days you also need an air conditioner.

This becomes increasingly clear the longer I am registered here in the forum, meaning it is becoming more and more clear to me that I won’t be able to avoid it. I would also most prefer to have a preparation planned, but because of KfW40, unfortunately all homeowners agree that they are not allowed to do that. So for the beginning I have to make do with it and hope that the ground cooling, the ventilation system, the insulation, and the shading will suffice for now (at least until I am once again awake at night, covered in sweat beads on my forehead, lying in my own juice, broiling away).

Fortunately, that is not a problem, our utility room is located in the basement and we sleep on the upper floor, so luckily there is a whole floor in between

In summer it is warmest on the upper floor, 25-30 degrees,
without air conditioning you sleep in the basement near the utility room and therefore do not plan the bed against the wall to the utility room.

without air conditioning you sleep in the basement

That’s a completely new point in the with/without basement discussion: The basement as a summer residence ;)

I will take your advice to heart :)

You will still have the pleasure of advising me on the property, probably more than you would like. I have to manage my time until the signing, so the property will take a back seat for now until the more important questions are asked and answered.
The question of the usefulness of also asking others who think along about my questions doesn’t really arise.

But you don’t do it (in time). Do you seriously want to be told only AFTER the signing, for example, that the house shape doesn’t fit well into the terrain, it would be wiser to choose another one, or the house needs to be rotated (but then also redesigned so that the HAR is located near the house connections)?
