Notes on earth and mud homes

This Thread (October, 2021) caught my attention for reasons that will be obvious. 

Gus Willard Van Beek (1920-2012, Dept. Anthropology, National Museum of Natural History, Smithsonian Institution) on the thermal properties of traditional earth and mud homes, citing a 1970s experiment in Iran. Stellar result from the "free dug at site material".

A preliminary understanding of how soil and earth works as a building material can be easily tested digging a hole and measuring the temperature therein. (Photo of the authors at a site in Egypt.)

In the late 1950s James Marston Fitch and Daniel P. Branch measured temperatures in traditional adobe homes in the U.S. Southwest. You really do not need air conditioning in a house built like this: the interior temperature is stable. (Example of a traditional home below.)

Back to the Van Beeks, who visited the traditional beehive homes in Fah (a village near Aleppo), in Syria, where they found the new concrete homes of the villagers very cold even in April and apparently unusable in the summer heat.

Wrath of Gnon is a substack with a wealth of information and links I simply don't have time in my life to add to my already overloaded list of interests.
