This survey paper offers a review of past and present studies related to air flow around multiple building configurations to achieve energy savings and thermal comfort in hot climate regions in the presence of increased urbanization. The purpose of this review paper is to provide guidelines based on previous studies for the successful design of group housing in a hot and arid climate such as Egypt to improve air flow around multiple rows of buildings. This study presents several types of

Next, air flow is described around one individual building and two buildings that have a passage between them. Furthermore, air flow around buildings is discussed to include several rows of buildings that range from rectangular linear to square shapes with flat and jack roofs, where the main goal is to achieve appropriate wind velocity at inlet surfaces, especially at the second and the third rows of buildings, and to avoid turbulence zones caused by wind around building. Finally, the effect of topography and urban mass on global wind velocity at the city scale is discussed.
