I just noticed that you said you've used the Slab program, but the results weren't believable. Slab is a simple 2-D conduction program. You should check your inputs again, it sounds like you're not inputting the right deep ground temperature or building indoor air temperature. I can't see how one can get a ground temperature of 17 C if all
the driving temperatures are way above that.

I hope you've also noticed that there's a time lag of about 90 days, i.e., minimum soil temperature occurs about 3 months after minimum air temperature.
