This beautiful building is the Zaued National Museum, currently under construction on Saadiyat Island, just outside of Abu Dhabi. Why do all the cool buildings get built in the UAE?
Here's the deal with the crazy wing-like design:
The towers heat up and act as thermal chimneys to draw cooling air currents naturally through the museum. Fresh air is captured at low level and drawn through buried ground-cooling pipes and then released into the museum's lobby. The heat at the top of the towers works to draw the air up vertically through the galleries due to the thermal stack effect. Air vents open at the top of the wing-shaped towers taking advantage of the negative pressure on the lee of the wing profile to draw the hot air out.Also, they look real pretty.
