If green roofs are too horizontal for you, consider green walls. According to a post over at Forecast Earth, the idea is catching on.
Like green roofs-their perpendicular counterparts-green walls are covered in vegetation and provide the benefits of natural insulation and removal of air pollutants. PNC, which provides banking and wealth management services, estimates it will be 25 percent cooler behind the wall than the ambient summer temperatures.The PNC wall features more than 15,000 ferns, sedums, brass buttons and other plants that create a swirling pattern of varying hues of green above the company's logo. They are divided among hundreds of 2-by-2-foot aluminum panels that were anchored onto the building's frame after part of the granite facade was removed....Green Living Technologies LLC, of Rochester, N.Y., designed the wall at PNC. Chief Executive George Irwin said the company also has installed walls in New York City, Los Angeles, Chicago and Seattle.PNC's green wall is claimed to be the biggest in North America. It's about the size of two tennis courts. The firm won't say how much it cost, but estimates for installations like this are in the $100 to $125 per square foot range. Green walls have all the aforementioned environmental benefits of green roofs. But, as the PNC example highlights, for businesses they also have another very important advantage over green roofs: You can easily advertise that you have one.Via Core 77.Photo from Flickr user PghFun1 (cc)
