Mist Jets These jets located at high level, humidify the air to make it cooler on the ground. It’s an evaporative cooling device.

As shown in the figure below, the design of the Balcony is for each apartment where it incorporates a shaded balcony, screened for privacy and solar control. As mentioned earlier in this paragraph, residential buildings are defined by glassreinforced concrete (GRC) screen that serve much the same role as traditional Arab mashrabiya screens. They provide shade from the sun, thus preventing solar gain on the building walls.
