The Iranian city of Yazd is full of windcatchers and qanats which use evaporative cooling. https://en.wikipedia.org/wiki/Windcatcher https://en.wikipedia.org/wiki/Windcatcher Highly reccomend a visit there. It's facinating. Also the roofs of some old houses in Malta have a small shallow pool to cool the house.
