The Crown Shyness system is an innovative concept that draws inspiration from the natural phenomenon of trees yielding to each other, creating beautiful patterns and allowing light to filter through. By adopting this concept, the prototype aims to provide view-outs and an abundance of daylight at user eye level while strategically designed with allocated spaces at the top and bottom for microalgae growth. Using Chlorella as a biochromic element, the system enhances air quality, controls solar gain, and stimulates biomass production. We are harnessing its unique properties to create an eco-friendly solution that benefits both humans and the environment. The biochromic capabilities of Chlorella not only contribute to air purification and daylighting but also add vibrancy and visual appeal to the overall design.
