This is why old buildings in the Middle East and North Africa have thick stone walls. In these arid regions there is a large temperature difference between day and night, so the thermal inertia of the building can be used to store the 'cold'. Structures such as windcatchers help to naturally ventilate the building at night. https://en.m.wikipedia.org/wiki/Windcatcher https://en.m.wikipedia.org/wiki/Windcatcher
