I’d recommend this article in the NYTimes for the term “green bling” alone but it also does a good job of presenting what’s good and bad about a hot new feature in the building world – vegetated walls. What’s bad? The systems break down, they’re heavy, people expect them to be low-maintenance and of course they aren’t. Too bad, coz they sure look cool.
I heard about another problem with them recently – pumping water to them takes a lot of energy. That’s why we won’t be seeing green walls at the new headquarters of the Department of Homeland Security. Architects nixed the green walls when they discovered that the energy needed to water them would jeopardize the LEED rating they were determined to win for the project.
A case of plants being green only in color.
