2400 sqft cabin - Need advice

I think that is draw atmospheric air through tubes under ground to cool it, then cool house with that (maybe heat exchanger, not drawing air into house?) and chimney draws it up to makes air flow.

Coolth tubes is another, given a hill, air is cooled and falls downhill in buried tubes.


 
That's very cool..... I think it's too late for me to plan that, but the concept seems pretty simple.

Also, I'm not too worried about Radon.... its only a problem if it concentrates in an area like a basement due to poor air flow. This type of system would encourage more airflow through the house, so even if it brought slightly more Radon into the house, it'll prevent it from concentrating in areas.
 
It depends on how much radon you have , it could kill you quick .
Then there is the mold thing .
Maybe drawing air from out side the house and bringing in sealed pipes to vents could work .
My place just stays at 67o all summer witha concrete slab and good insulation .
