A Case Study in High Efficiency
The Bio-filter Living Wall system at the Edmonton Federal Building is the focal point of the large glass public atrium, the newly added grand entranceway into this rejuvenated historic building. The living wall and associated water feature provide a calm and serene environment in the busy public space. The vibrant layered and organic pattern of the plants makes the wall a work of art, and provides a foil for the otherwise angular and clean-lined space.
In the Edmonton Federal Building project, landscape and urban design were extremely important. The exterior of the building features numerous green roofs and an extensively landscaped plaza featuring local and native plant species. Utilizing a green wall within the building seemed the next logical step to ensure that the objectives so carefully considered on the exterior of the building also translated into the interior.
However, this living wall is not only aesthetic; it is also a working element of the building’s mechanical system. Air is actively drawn through the wall of plants, where biological components degrade pollutants such as formaldehyde and benzene into harmless constituents of water and carbon dioxide. The living wall also filters fine particles such as dust and spores. Once these processes have occurred the air is distributed back to the space mechanically. The living wall also contributes to the humidity levels of the atrium space contributing innovation points to the LEED Gold certification goal.
The judges felt that this project presented an excellent integration of living wall technology into the public space of the building in both a functional and beautiful way.
