Catch 22; proper insulation (1' cellulose @ R 3.8/inch = R 45.6 or whatever R value a bale would be) would negate the need for 5' thick cob, but if 5' think walls if used inside a complete high R value envelope which would include the floor (more than R 15 if there were a slab) and the ceiling and the foundation, walls if any. It would help if condensation/dew point interior to the wall and vapor barrier issues were be understood. Anyhow, with super insulation the cob should take on the avarage temp of the interior of the house, however the 5' thick walls would not be required. The cave issue is a big issue. Most designers and even feng shui practitioners (geomancy is incorrect) http://en.wikipedia.org/wiki/Geomancy care a great deal about the quality of light inside a house, and 5' think walls not only cut down on the amount of light that enters the house but also greatly limit the view out the window. Think of placing a window shaped 5' long tube sticking straight out and imagine the view out and the reduced light coming in. You and I agree, are their other opinions? Hugs, Shody
