I once overheard that it is wise to lead the supply air for the [Kontrollierte-Wohnraumlüftung] a few meters through the ground and possibly through a gravel bed to condition the air.
This should preheat the air a bit in winter and provide pleasantly cooler air in summer.
Now the question is, does the effort really pay off that much and how many meters in length and at what depth should it then be installed??
