CIRCADIAN CLOUDS TO COOL DOWN CITIES

Architecture and engineering consultancy EMKAAN have conceptualised a circadian clouds design that will aim to cool down the urban environment. Using floating, drone-like cells, EMKAAN aim to transform this idea into reality in the near future.

To maintain thermal comfort, a shading system, comprising of multiple small floating cells, will work together in synchronisation to move with and block the sun. This intends to keep a targeted area in the shade at all times, while ensuring minimal sky blockage. Its adjustable form is inspired by the movement of flocks of birds in the sky and how the sunflower follows the sun.

Although it resembles a cloud, the design is actually formed by an orchestra of small, synchronized floating cells. The cells are lined by a structure of sunlight sensors, photochromic panels and 3D rotated fans, which help it control and adjust its position. A helium balloon then sits at the centre of the cell. Its sunlight sensors help the drone-like devices to detect, respond and follow the sun to continuously block direct light. Collecting energy through its photochromic sheets, the cells disperse and light up as if scattered chandeliers at night.

The areas that are covered will still feel outside, as only direct sunlight will be blocked. The clouds also function as a gateway element to help wind flow in cities and towns as another measure to maintain thermal control. The result engages the community by enabling a public space for different, enjoyable activities outside.
