The Challenge

The ‘urban heat island effect’ is the phenomena in which cities experience much warmer temperatures than nearby rural areas. These high temperatures cause elevated energy consumption, increased air pollution, and other side effects harmful to humans.

Innovation Details

The Fractal Shade® structure uses Sierpinski Tetrahedrons, a fractal pattern based on the equilateral triangle, to mimic the shade provided by natural tree branches and leaves in a forest canopy. The result is dappled sunlight with continuous air movement, helping to cool the surrounding area.

Biological Model

Staying cool, especially in subtropical regions, is essential. Shade trees provide a cooling effect by blocking sunlight and increasing air moisture. Tree species with rough, dense foliage and light colored leaves provide the greatest cooling benefits to their surroundings.
