Egypt is an origin of many cultures and theories starting around 5500 BCE along the Nile. Cairo is characterized by its hot and arid climate. Traditional Houses are covered in variations of domes, vaults, and flat roofs that represent both visual and spatial characteristics. Hierarchy highlights the importance of exterior & interior of the building. Harmony with surroundings lifestyle inspired the design process.

The Egyptians invented a system of ventilation which consists of Malqaf (wind-catcher) and Salsabil (rippled marble slab inserted in an opening in the wall in the living area with water and fountain). Circulation takes place when wind enters through the wind-catcher and Mashrabiya.

The natural depolluting wind tower is inspired by a system of ventilation invented by Egyptian people and consists of Malqaf and Salsabil. This wind tower makes use of harvested rainwater to help transfer pollutants from air to water and raise humidity in the air.

A bad quality air enters the wind tower through the mesh screen at the openings then travels down the chimney, passes sloping slabs that redirects, spins, and separates dust from the current, generates convective heat transfer forced by movement of fluid. Pollutants are trapped and stored inside and between slabs. After picking up pollutants, contaminated water that was at first released from the sprinkler tap at the opening flows down to be pumped back to the contaminated tank. The water purifier filters and sends clean water back to the freshwater section.

Finally fresh air carries moisture and increases humidity of the air current as well as reduces temperature of air. In addition, fresh water is partly distributed to grow small plants in form of a green roof so that the wind tower can provide people more than just as a device, but a small shaded shared space around the site.
