According to a press release, see below, “AIGA has just installed a green roof?a vegetated roof cover?at the AIGA National Design Center in New York City. Weston Solutions, Inc. was contracted to create a 1,156 square foot GreenGrid roof system to top the four-story historic building. Eight varieties of sedum are planted in four-inch deep containers, lined by a walkway of recycled rubber pavers.

“This initiative is part of AIGA?s ongoing environmental stewardship effort. Green roofs have been shown to reduce heating and cooling loads on a building; counter the urban heat island effect; filter pollutants and carbon dioxide out of the air; filter pollutants and heavy metals out of rainwater; as well as increase wildlife habitat in built-up areas.”
