This project is an inquiry surrounding the development of a water community around Six Mile Island on the Allegheny River in Pittsburgh that integrates ecological factors as design drivers. The project explores how green algae can be employed as an agent for dynamic shading and unique architectural experiences. The eco-machinic nature of this project revolves around a study of the stochastic behavior of algae in turbulent flow. In order to facilitate growth, algae must be periodically sift between states of intense light and darkness. Based on this principle, the algae’s position in relationship to an aperture in a container can be determined probabilistically through the use of a Markov chain. Algae is employed within the wall poche to create a dynamic shading device based on its proximity to sunlight. This generates an experience of varying opacities. Depending on the time of day, spaces in the housing units undergo differing levels of privacy of daylight, encouraging a more fluid way of life.
