Central ventilation system - cooling/heating air through underground pipes?

Hi guys,

a friend who has been operating a central ventilation system in his house for 15 years gave me the tip not to direct the air sucked in through the snorkel in the garden directly into the house, but to temper it to 10 degrees via a pipe buried in the ground. He buried and laid a simple KG pipe in front of the house, which lets the air pass through about 20 meters (buried at a depth of 1.20 meters).

This way, the air is pleasantly cool in summer and warm in winter (relative to the outside temperature) – always 10 degrees.

I haven’t read about this anywhere yet, but I think the idea is brilliant. Is there anything speaking against it?

Regards

Great thing that! Google "Luftbrunnen" and "Kontrollierte-Wohnraumlüftung". Disadvantages: work (so-so), costs (manageable). Space requirements. Provide condensate drain / discharge at the lowest point via [Revischacht]. Note: As always, layman's opinion. My knowledge is only secondhand, i.e., theory since I couldn't implement it with us (space / time).
