LIVING WALL

At the University of Guelph, near Toronto, green design is a literal term. The new Humber building, designed by Toronto firm Diamond Schmitt Architects, Inc., uses a wall of plants as a living air purifier for the 170,000-sq.ft. building.

The four-story biofilter is a thick jungle of ferns, ivy and other plants, working together to emit microbes that break down harmful airborne contaminants into water and CO2. The wall is self-cleaning, since pollutants are not absorbed into the plants, but actually broken down.
The biofilter was developed by biological researchers at the University of Guelph, including Alan Darlington, who now heads his own company, Air Quality Solutions, Ltd., to sell the living walls commercially.
