Oh, you mean geothermal cooling. Yes, some buildings use that for heating/cooling by using vertical wells or buried horizontal loops coupled with heat pumps. It’s fairly green, though can be an expensive investment up front if one needs to use vertical wells due to lack of real estate. It’s still air conditioning, just coupled to underground water as a heat sink instead of outside air.

The DIY method I mentioned is just dumping heat into the ground using water to transfer it. No heat pump, just a pump and much cheaper. Of course anything with a heat pump is going to be more powerful. Not sure how many watts of cooling something like that could realistically manage but I have been interested in the idea.
