One of the UAE’s national pavilion’s most noteworthy features is the winged structure on its roof. It contains 28 wings in a hybrid shell and portal frame. The wings, which symbolize the flow of movement, can move in a multitude of ways, between 110 and 125 degrees, and are powered by 46 specialized and synchronized hydraulic actuators that serve the function of pistons. There is another eye-catching feature on the rooftop: the Oculus skylight. Designed to mirror the Expo 2020 logo, it is a fixed insulated glazing unit system that would let in light, while also maintaining cooler temperatures indoors.
