The Al Bahr Towers have a wonderful façade design for the climate here in Abu Dhabi. Designed by Aedas Architects and Arup Engineers worked together to design a folding active geometric patterned façade that actively moves throughout the day to block the sun from having a harsh direct impact on the building, but allowing a wonderful view out the windows when the sun is at an acceptable angle. I have had the opportunity to drive past these towers during different times of the day. Although unfortunately, I couldn’t get a good photo of it several times. I also learned that here in the Gulf region it is rather common for the architect to come up with a general façade concept and the sub contract out the actual technical design of the final façade. I don’t know how that worked for the Al Bahr Towers, but for many of the building surfaces here the facades can be quite complex.
