I was curious how a cob home would perform compared to an earthship style home. Would 2 1/2 feet thick wall retain enough passive solar energy to be effective in heating and cooling situations. Cob appears to be cheaper to finnish a project. I understand a cobb home may not have all the features of an earthship but was looking for insight into how cobb compares. Thanks.

I saw a video where they are building an earthship in FL. If they can do it there. TN should be easy. Look for it on youtube. They are drawing cooling air in thru the ground at below 7 ft. The air temp there is about 72 degrees. I had thought of running drawn in air thru a small water cooled radiator to extract moisture. (humidity)
