Remodeling Analysis: In the Urban community redesign, the tunnel based notion placed at the top as a coverage that launched from the site entrance to the site exit and placed comprehensively in the middle of the site in which directed the wind airflow to increase its velocity and to engage to follow in the same course of the design with an estimated wind velocity speed between 11 to 13 m/s as shown below in Figure 22 (left). Figure 22: Wind flow is running and intensively penetrating the central courtyard with variable wind velocity speed between 11 to 13 m/s (left); flow design simulation demonstrating wind circulation throughout the site (right) As a result, the remolding design passively captured the wind, directing the wind flow in the site and circulating the air in and out of the urban community as shown above in Figure 22 (right). Additionally, captivating a focus on the central courtyard and providing with bounded amounts of air circulation (Fig.23 -left), which also resulted in repeatedly ventilating the existing courtyards aligned in the urban community (Fig.23 -right).
