Climatic Treatments for Housing in the Traditional Holy Cities: A Comparison between Najaf and Yazd Cities

The hot, dry environmental conditions prevailing in Al-Najaf and Yazd cities - a modern old problem-must be studied with some detail to come up with new solutions to adapt to the current environmental conditions of the two cities. the research aims to compare the methods used by the residents of Al-Najaf and Yazd cities to handle the hard-environmental conditions in the past and the way to adapt to them. Eight criteria were compared and discussed to investigate the ways and methods to improve the environmental situation in the two cities. The research concluded that there is a great similarity in the environment of the two cities, as well as the environment responding to the treatments that human life adapts. This necessitates the need to preserve the environmental design vocabulary for these two cities (Yazd and Najaf) such as the central courtyard of the aligned residential units to soften the atmosphere within the one unit and increase the family bonding.in addition to preserving the side Shanasheel and local privacy. Yazd city overpass Al-Najaf city by maintaining climate treatments for the historical centre and developing them in line with the development of building methods and construction materials.
