PNC, a US based financial services corporation, has installed a green wall on its headquarters in Pittsburg (Pennsylvania). The green wall is a horizontal area of vegetation that covers approximately two tennis courts. Benefits of such an initiative include natural insulation and removal of air pollutants, a drop in temperature within the building (roughly 25%), as well as the capacity to display a positive public image. The wall was installed by Green Living Technologies LLC, which provides products and services that facilitate and simplify the integration of environmental technologies.
