Cob: mass house/oven

[Darel Henman]

Charmaine,
  You are right if you have a normal cob building in a climate that does
not have cool evenings that whatever heat trapped in the walls will
radiate out. 

  Here are some more thoughts on the subject and queries.

  In climates like this it may be usefull to use a lot of thermal mass,
i.e., berming and going down into the ground or into a hill, or other
type earth sheltered structure.  Enough thermal mass should give you a
seasonal lag, not just a daily lag in temperatures.

  For example what is the temperature of the earth five feet down in
Arkansas in the summer?  

  Have you ever been in an basement is Arkansas during the summer.  Is
is cool?  

  Any caves to take temperature readings there?
