Vegetation analysis using ‘SketchUp’ for thermal efficiency in redesigning, while mimicking the
natural concept by adapting and strategically planning a breathable design and a living community, has been undertaken within the selected case study (Fig.24). Natural shading can be used
to create shading within the surrounding of the buildings. Palm trees, Proscopis cineraria (Ghaf
tree), Zizyphus spina-christi (Sidr tree), and Cordial sebestena with lively yellow flowers planted
throughout the site. The housing blocks lack shading as they are joined by long and wide walkways. The shading and vegetation improved the thermal comfort for pedestrians and produced
oxygen in return. The walkways are designed to be pedestrian friendly with shading devices that
allow the light to enter through the designed louver.

Water surfaces have the ability to absorb the heat from the air. It takes the warm temperature,
stores it, and releases a cool breeze instead. The water features are located with the houses and
one big central fountain with vegetation surrounding it in the courtyard (Fig.24). Within the house,
the fountain is placed in the courtyard under the semi-covered retractable awning positioned on
the roof to allow passage of air to the fountain as shown in Figure 25. This resulted in a reduction
of heat gain and the reduced temperature can be directed through the interior of the house for
natural ventilation. Pedestrian walkways are uncomfortable for exercising or utilized as a mean of
transportation through the neighborhood (Ferwati 2012). The overhead louvers can create a social
magnetic that attracts residents to exercise and interact with others throughout the day and year.
