The Library is once again innovating with its installation of the University’s first living walls, nine of them, to be precise. Concordia has opted for the Envirozone living wall system. The company is based in Montreal.

“Several years of research and experimenting have enabled [Envirozone] to develop a [slow-drip] capillary hydroponic system that reproduces the life principles of the rainforest.ˮ Envirozone consultants selected resistant species such as philodendron “lemon limeˮ, pothos “neonˮ and pothos “marbleˮ and will plant them according to their tolerance to various elements. This is why green walls regenerate naturally and are easy to maintain. Each installation is custom-designed for a specific environment with both aesthetic considerations and functional needs in mind.

The benefits of living walls will be many: they will allow for a better air quality by absorbing CO2 and fine particles, lighten the load of the HVAC system and reduce noise through absorption. In addition to allowing for an overall sustainable living environment, living walls are a fire retardant and help to offer an overall feeling of well-being to users. These nine living walls will be installed this fall, thanks to the Library Services Fund.

Finally, watering the living walls will be accomplished through a sophisticated automatic irrigation system designed to eliminate complexity for the occupants. The plumbing infrastructure for the irrigation system was integrated in the design of the Webster Transformation and executed during the renovations by Pomerleau.
