What is the history of cooling a home in summer

Cooling a home has become more important for many of us during long heatwaves in the summer. While today our air conditioning bills might reflect the need to keep cool, long before such technology people practiced different methods to keep cool. Some of the techniques might even give us a few ideas to keep our homes relatively cool for less money.

Early History of Cooling

By the late 4th millennium BC or at least early 3rd millennium BC, it was evident that if people were going to live in cities then they had to figure out a way to keep cool. In Mesopotamia, modern Iraq and Syria, the earliest cities already show evidence for cooling methods. Already by 7000 BC, homes were made of mud in the Middle East, which allowed them to stay relatively cool in the summer months. Mud insulates a home from heat seeping in during the summer, while it also acts to seal in heat during the winter. However, to live in larger cities, home also had to be designed differently. One form of design that helped things stay cool was to keep houses near each other. Cities were very compact, which helped to create more shade. This allowed many homes not to receive direct sunlight at all hours and created shade for people to move around their homes, courtyards, and neighboring streets. The use of mud for construction material also enabled homes to stay relatively cool by insulating homes from outside temperatures.
