DYNAMIC SHADING DEVICE FOR AL BAHR TOWERS

In generating the form of the two structures, the design team applied an algorithmic composition informed by Islamic principles of design. Combining technologically advanced solutions while considering the country’s architectural heritage, the dynamic façade opens and closes in response to the movement of the sun, reducing solar gain by up to 50 per cent.

Referencing the ‘mashrabiya’, a wooden lattice system found in vernacular Islamic architecture, a series of translucent umbrella-like components which open and close in relation to the sun. Each shading device is driven by a linear actuator and dramatically reduces the amount of sunlight striking the building, avoiding the need for tinted glazing.

Starting with two cylindrical volumes, the circular plan form was articulated to reduce solar exposure, generating a natural orientation. Shaping the building around this core, the towers become broader at their mid-height. At the peak of each structure, the crown of each edifice is cut at an angle, configured to maximise solar gain for the roof mounted photovoltaics Sky gardens at the upper storeys provide external areas of recreation at roof level.
