 Yazd province in Iran have arid climate with low amount of rainfall. In order to adjust commercial and residential buildings to this climate, one of the structures are domes. This structure have been built on the roofs from local material such as mud and brick that transmit the heat slowly from the roof (  Ahmadkhani Maleki2011).Domes are usually in the way of intense wind in desert areas that makes them cool and therefore makes the building cooler. Furthermore domes decrease the intense sunlight in arid areas because sunlight is not equal in all direction of them (Keshavarz 2011). With all of these features these kind of roof could be considered as sustainable roof which can adjust building to harsh climate with out using energy for cooling which can increase carbon emission. These roofs have been structured in the past and but residences maintain them. Nowadays there are modern dome structures with same features and advantages. Queen Alla international airport in Amman is a good example of usage of domes in modern sstructures in desert.
