Cooling was an additional function available from a technique of irrigation widely used in the middle east starting around 3,000 years ago, called the qanat or quanat, based on digging horizontal tunnels into alluvial fans or mountainsides to provide water in desert areas. These ran for many miles, with regular openings to the surface. Cool air was drawn into houses through a wind tower.

I am trying to find a site I saw once before which describes the use of
underground cooling tubes which brought cool air into the house without the
use of fans. It seems to me the drawings were of nonwestern architecture
and may have had rooms around a courtyard as well.

Does this sound familiar to anyone, or do you know of other sites that
describe this well and have examples?
