The two 25-storey office towers are parametrically designed based on islamic geometric mosaics, using the tessellation of simple shapes to drive the structure. The cylindrical forms maximize volume and floor-to-wall area while offering views in all directions, unfortunately however, this also opens the interior to a very large solar gain factor which is a substantial problem in the extreme local climates. The Al Bahar Tower’s innovative dynamic façade opens and closes in response to the movement of the sun, reducing solar gain by more than 50 percent, creating a more comfortable internal environment for occupants and producing a distinctive external aesthetic which helps to define the building as a gateway to the UAE capital. The façade was conceived as a contemporary interpretation of the traditional Islamic “mashrabiya”: a popular form of wooden lattice screen found in vernacular Islamic architecture and used as a device for achieving privacy while reducing glare and solar gain. “The dynamic façade on Al Bahar, computer-controlled to respond to optimal solar and light conditions, has never been achieved on this scale before. In addition, the expression of this outer skin seems to firmly root the building in its cultural context.”– Chris Wilkinson.
