CitiesAlive 2011, the international green roof conference we’ve been blogging so much about, came and went this past week, and it turned out to be an awesome learning experience for everyone involved. From professional classes that taught conference-goers advanced green roof maintenance techniques to hands-on tours of Philadelphia’s most progressive green roofs and walls, there were tons of opportunities to find out more about the economic and environmental benefits of green roofs and the specifics of their installation and upkeep.
On my three-hour-long tour of the green roofs on the U-Penn and Drexel campuses, I had the privilege of discovering green roofs and walls where I didn’t even know they existed: namely, on top of Penn’s Radian apartments on 40th and Chestnut and inside the atrium of Drexel’s Integrated Science Building.
I also learned about a house Drexel engineering students have designed to have the lowest possible environmental impact called “Smart House.” The house design includes an extremely lightweight green roof that weighs in at less than ten pounds per square foot (where most green roofs weigh almost twenty-five pounds per square foot of saturated medium). I also met so many interesting and dedicated people whose passion for green roofs and reducing stormwater runoff was positively inspiring—yes, I recognize that might sound silly to some people.
Another tour offered green roofs and great views in Northern Liberties, Kensington, and Fishtown. I wasn’t able to attend that one, but the CDC blog has it covered, complete with photos. Click here.
Speaking of residential green roofs, PHS employee Jane Carroll and her husband decided to have a green roof installed on their house. It’s pretty cool, and if you’re curious, you should check out Julie Snell’s video documentation of the project below:
