Maybe I am wrong, but I do not believe that thermal mass works very well in the deep South where the temperature does not vary very much. However, if solar insolation is introduced to the home, then mass could be beneficial.

I am referring to the R-45 and how much can thermal mass mean to the efficency of the home than that... Also if the home is built tight and has super insulation then why would you worry about the thermal mass??? Kelly

Thermal mass combined with the right use of night cooling a solar chimneys can reduce the need for air conditioning. Who would not want to lower their electric bill?

Really, only if you were trying to incorporate some Solar into the mix. Otherwise, I wouldn't expect much of a payback. Super Insulate, seal everything well, ventilate properly, and you've done way more than most, and you'll reap the benefits.

....jc If you're not building with OSB SIPS(or ICF's), why are you building?

"It also insulates the house from the humidity and moisture that will collect on a concrete wall. If you are using a regular heating system, It will cost you more to charge the wall then you will re coop from it." These things might be true if the concrete wall was not insulated externally.
