This document describes the Bio-Wall, a modular wall partition system that incorporates greenery. It consists of hexagonal units that can be stacked and connected to form a structure. Each unit contains a planter through which water cycles from the ground level up to the top of the structure and back through pipes. The watering of the planters forms a self-sustaining cycle. The Bio-Wall can be installed both interior and exterior, and can serve applications such as a cooling system, counter, seating, or sunshade through configuration of the modular units. Detailed sketches and models were created to design the connections between units and establish water flow.
