CHBE Biowall

Congratulations to the CHBE Sustainability Club for receiving the Fisher Scientific Green Fund for the CHBE Biowall Project. A small scale biowall was constructed in order to demonstrate the effectiveness of vertical growing of plants for enhancement of indoor air quality and the well being of building inhabitants.
On February 16th, the Fisher Scientific Green Fund was awarded to the CHBE Sustainability Club for their proposed biowall project. The project was lead by Lindsey Curtis and Maggie Stuart, in hopes of enhancing the indoor air quality in the CHBE building. The wall was built at the end of March and is a mobile system which can be found either on the 2nd or 6th floors of the CHBE Building. The design was done by James Butler of the Sustainability club, with help from Tyler Lewis for construction.
Biowalls are indoor biological air purification systems that are composed of a variety of plant species and microorganisms that live in their roots. The plants are typically grown on a vertical surface which allows airflow through the wall, and over the root system. Through microbial activity, airborne contaminants such as carbon dioxide and VOCs are degraded into end products that are harmless to humans and the environment. The biowall structure can be built into the building or attached to the outside of a wall with cladding.
The wall is a small prototype for a larger integrated wall and its mobility will make it available for presentations across campus. The wall is equipped with an automatic irrigation system, as well as six fans on the back to pull air through the wall and distribute it throughout the room. Preliminary testing has shown that the wall reduces carbon dioxide levels as well as volatile organic compounds.
Several eastern North American universities have implemented biowalls as indoor air purification systems and we hope that UBC will be the first western university to implement a similar structure in the near future.
