Figure 20: Flow Design analysis simulation demonstration. The lines in the figure shows wind flow, color of lines represents speed and pressure as per the legend on the upper left side. The values on the right represent the preset values, which are the same in both before and after design Existing Site Analysis: In the existing site analysis, Flow Design demonstrates the wind functions that are completely ignored in the original site design. As can be seen in the existing site model below (Fig.21), the wind is simply flowing on top of the buildings and not reaching the urban community main central courtyard ‘plaza’ and also the rest of the urban multiple courtyards are not exposed to wind ventilation. Furthermore, the wind is essentially interrupted by the unproductive building initial orientation, building mass and the inefficient building arrangements. As a result, the existing urban community is not entirely utilized by any method or passively used or proficiently directed in which the flow design simulation below demonstrated as seen by the wind entering the courtyard, which is vertically none (almost zero).
