What is a Biowall?
Put simply, a biowall is a vertical garden. Plants are rooted in layers of porous material that is attached to a concrete wall. The plants are held in place by their roots, which grow downward between the layers. Typically a biowall is connected to the building’s HVAC (heating, ventilating and air conditioning) system; as fans pull air through the wall into the office spaces, bacteria in the plants’ roots act as a natural air filter, removing VOCs (volatile organic compounds) and CO2 (carbon dioxide) from the air.

Why have a Biowall?
The biowall is both a central aesthetic feature to the office and a beautiful solution to improving indoor air quality, as researchers are increasingly establishing a link between indoor air quality and the productivity and health of individuals.

The wall requires no more maintenance than any other indoor landscaping feature. Water from a basin is pumped to the top of the wall and cascades down between the layers, wetting the roots of the plants. At the same time, the plants are dusted, wetted, and pruned, from time to time, to ensure their vitality and to maximize the benefits of the wall. The constantly running water and fresh air prevent mold from getting a foothold, and the plants are specifically chosen to spread no pollen.
