The wall of lush tropical plants, 20 feet wide and 75 feet high, is what greets students and faculty every day inside Drexel’s Papadakis Integrated Sciences Building.
The Delaware Valley Green Building Council oversaw the ambitious project that was unveiled last September (see previous story), and now it’s showcasing it to other environmentally conscious builders looking for the next big thing.
Board member Pat Bolger says a biowall is not only easy on the eyes, it’s also great for cleaning the air thanks to an exposed root system and hungry microbes.READ MORE: The Aztecs 'Slowly Crush You': CBS Sports' Randy Cross Previews Fresno State-#21 San Diego State, Other Matchups
“You have misting stations behind the wall,” he explains, “and then you have air ducts taking in the ambient air and processing it so you get clean air coming out. It’s one big air filter that is cleaned by the roots, but you have the aesthetic value of the leaves that make it very warm and inviting.”
The recirculated air cuts out the need for drawing in air from outside, thereby cutting down on energy bills.
