When you move the heat from the building to the ground you are actually 'putting it into the ground'. That's a lot of heat. I've heard of cases where the ground temp has actually increased significantly, like to the 80's Fahrenhite. That earth has an ecology, and many of the organisms in it cannot tolerate such changes in temperature. If one upsets that ecology, it is a chain reaction. The waste by-products of one species feeds the next in the change. That simply won't do. Second issue no one is addressing, is the change in the frost line. Buildings are engineered with the location of frost lines considered. Driving heat into the ground can do away with that line. Taking heat out of the ground may cause it to progress downwards. Most building foundations are set to a depth to accomodate where that line is. Moving it may have significant effects. I would check with an independent engineering firm before making any decisions.
