How Green Roofs Can Help Cities | NPR
We took a field trip to the largest green roof in New York City. Then we imagined what the city could be like if all of its roof space was green.
Note: A previous version of this video incorrectly thanked the Audubon Society. We meant to thank the NYC Audubon Society.

yesss. why haven’t we covered every roof in grass years ago!?
Stats: $3M saved, 7 million gallons storm water absorbed, 26% less energy used, 6°F cooler, 25 bird species, 300,000 bees. NYC est. 1B sq ft roofs. Asphalt roof temp as high as 170° vs. green roof 80°.
So if you add a green roof on a flat every floor will be cooler?
@Sui Des It’s a joke…
JaxTCEK cant you read?
So… pretty much a waste of time with no benefits whatsoever
I do hope the Australian Government is wise enough to introduce these positive movements.These can provide employments and attractions by annually contests,designs and trends.
Hi logan
I would love to become a gardener and taking care of the garden everyday.
I am so happy that this video exists. I studied green roofs and their benefits for my honour project and everything said in here is scientifically accurate. It makes me hopeful, especially the energy saving potential it gives. Keep it up NPR, I am rooting for you and this project!
@Whatsername868 email sent, let me know if you didn’t receive it 🙂
@Whatsername868 yeah of course, I don’t know how to send a private message on YouTube though haha I just use the app for music and sharing stuff with friends. If you know how to, please feel free to do it I’ll give you my email then
@Nicholas Noto Thanks for the idea to hop on LinkedIn! I don’t use that site too often and always forget it’s probably a good resource. Yay #greenroof!
Whatsername868 I’m sorry about that. You should follow up! She may be busy but that could mean your email was buried and she overlooked! I know roofing is really slow right now. I’m not sure if you’re on LinkedIn either but there’s plenty of ways to network on their as well, and you can search hashtags for certain topics to find the right people like #greenroof. Good luck!
@L Popov Hey is there any chance you’d be down to chat a little bit through email? Im super super curious about the research you did – actually if I go into green roofing Im hoping to move around with it somewhat and possibly even get it going in South Korea.
6 dislike’s must be made by some antinational’s
Green roofs are getting more popular. The Science Times just released some new research about green roofing.
Very informational and helpful! Thank you NPR?♥️
Are there structural changes necessary for most green roofs? the weight of the soil, plants and especially holding the water that was initially designed to just run off seems significant.
You first talk to the structural architect and then you calibrate the green roof to match the structural capacity of the building. There are options within the range of 15lbs/sqft to 200lbs/sqft depending on your needs. Plus, there are new Detention based green roofs on the market that perhaps weigh a little extra but do so much more for the stormwater management in a city. see http://www.purple-roof.com for ideas.
Hi there. Green roof systems are tailored to match the structural capabilities of the roofs their on, and plenty of extra weight capacity is left over in the design for snow load and people, etc.
I would imagine if NYC roofs are prepared to take on the weight on snow storms piling on each year they would probably be up for the task? But that’s just my guess, I don’t know.
I love greenroofs. As a water engineering student I would love to work and build all those greenroofs. 🙂
0:26 I think he looks like a blonde and older version of Elon Musk XD
Knowing that the roof has a certain load limit I wonder how often they’ll need to haul down the excess bio mass.
Hi geography 9
Also, where possible, wetlands, porous paving to help control stormwater runoff.
Good initiative.
l concur
YES! Thanks a lot for making a video about Green roofs.
Imagine how beautiful it would be
Yeah they do! So much unclaimed potential. Thanks for this great video showcasing the net benefits of a green roof. We live in an exciting time.
Thank you for sharing. Michael Legit nailed it at 2:44 when he mentioned Ed that many green spaces are “unconnected” to other green spaces which means that pollination is drastically more difficult.
