While my solution would be difficult for a large building, it does work
on a small one. My cooling coil is under a garden bed that is watered
everyday. This helps wash the heat away and keeps my place cool. The
other option is a shaded, deep pond. Just make sure you run your lines
far enough apart to not heat your cool with the return heat.
