Green Walls- In the City and at Home

Green walls clean up the air by filtering urban pollutants and absorbing CO2.  In addition to reducing air pollution, green walls reduce wall surface temperatures by as much as 50°F, resulting in significant energy savings and air conditioning costs, are visually pleasing with a variety of colors, textures, patterns and sizes, reduce noise levels by reflecting, refracting, and absorbing acoustic energy, naturally absorb and filter stormwater, cause people to feel more relaxed and less stressed, and increase biodiversity by attracting beneficial organisms, such as birds, butterflies, bees and ladybugs.

The Bellevue Library's new three story parking garage, which opened in June of 2013, features green walls on its north, east, and west facing walls. The largest is the east facing wall, along 110th Ave. NE, pictured here. The walls were designed by Canadian firm Green over Grey, and consist of more than 80 species of plants.
