Green Walls May Cut Air Pollution in Cities
I’ve made a couple of posts about vertical gardens and one the other day about green roofs…Well this is another interesting take on incorporating plants into architecture. Studies have shown that green walls can remediate levels of air pollution by trapping particulate matter and gases like nitrogen dioxide—this is especially useful in hot summer months. Photosynthesis is pretty cool, eh?
Also, buildings with green walls require less power, thereby reducing their emissions of pollution by-products. Models have shown that creating a corridor of buildings with green walls can mitigate air pollution in large amounts. China? India? U.S.? Anyone out there?
