7.2.2 Compact plans with interior courtyards that allow air circulation

A recommended northern courtyard with link between the courtyard and the backyard at the south orientation has been modified to the design. This can affect positively the thermal performance of the building. This link could be positioned at the first floors "called Takhtabush in vernacular architecture." This could be achieved by replacing the curtain glazing in this area to contemporary electronic Mashrabia (Figure 7).

This ensures a steady flow of air by convection [74]. Since the backyard is larger at the south orientation, and thus less shaded than the courtyard, air heats up more than in the courtyard. The heated air rising in the backyard draws cool air from the courtyard through the Takhtabush, creating a steady cool breeze.
