Are there many ADOBE buildings in Texas?
(Remember the Alamo?)
All of the adobe buildings I have experienced here in California are very well suited for keeping cool in daytime heat. Adobe makes for excellent insulation.
The key is that the temperature needs to go down at night to a reasonable low, such as perhaps 70 F. If the building is allowed to cool off at night, then it is easier to keep that cool all day long as the interior temperature rises much more slowly than the exterior does.
