OK, I got it wrong again. Yes, I recall that was what Phil was saying.

The ground temps are hovering near 50F right now as we are near the end of heating season. Phil can look at year ago data to say what his ground loop temps are in July. So long as they remain below about 60F at the peak of summer, then yes, Phil could get a valuable assist in his cooling by installing a fan coil and circulate ground loop water thru it. Fan Coil could mean taking an AC evaporator coil out of an old unit, soldering adapters on it to route cool water in/out, and installing a fan to run when the thermostat calls for cooling.

I am not aware of anyone who offers a packaged solution to this situation. The fan coils that I have seen out there appear to be directed towards a heating solution, not a cooling solution.

I put this in the same bucket as the folks who say that a few hundred feet of PVC pipe buried 6 feet underground with a soaker hose over the top will heat and cool almost any house in the USA that has adequate thermal mass. Both are risky approaches, in my mind. Both need a backup in case the primary solution (fan coils, PVC pipe) does not work.

This site is all about building a cool, energy efficient house, that makes maximum use of earth sheltered design, passive solar heating and cooling, geothermal exchange energy management, and right sizing of the house for it's designated use. The home's placement is on a south-facing hillside in Deep Creek Lake, Maryland. This site describes the design process, the technologies used and the expected results. We also have a comprehensive Links Page for anyone who is also interested in designing a similar project.
