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!
Hey so I just stumbled upon green roofs as a career idea...do you have any idea how much green roofing businesses make? Would love to chat more about what you learned!!
@@Whatsername868 Reach out to Angie Durhman of AD Greenroof LLC in Minneapolis Minnesota. I dont have a contact info for her but you should be able to find her business and contact her through that. She will be able to tell you all about it, bc its what she literally does. Better to ask someone who actually does it
@@Whatsername868 hi, sorry for the delayed answer. I unfortunately don't know if it is a highly profitable business or how much money it makes, but I am certain it is a safe long term business if done right. What I tried looking into but didn't follow up on was to figure out if it was possible to get government and/or bank deals to fund you and/or your clients, in order to encourage the installation of green roofs. One of my dreams was to see a world in which every single building which could physically hold a green roof, to have one on, especially in cities since that's where it has the most impact. I didn't take the time to analyze it so I guess it's worth looking into. Good luck!
@@popov1993 That's really cool that you did research on that! Can I private message you for your contact and chat with you a little more through email about stuff? I'm really curious about this field and really the only way I've found to learn more about it is from online digging!!
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°.
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.
There’s also the benefits of food security, hands-on learning for children, air and water pollution mitigation, carbon sequestration, stress relief/ mental sanctuaries for people, and an opportunity to bring communities together.
I live in Ireland and the government has let parts of parks grow wild to help insects travel instead of cutting down weeds. It helps them survive and helps insects like bees pollinate a lot easier 😎 definitely onto something with the green roofs !!
Amazing video! Well done! Green roofs provide so many urban benefits yet six years on, NYC is no closer to this beautiful vision outlined in this film. Wondering what it would take to make it a reality. Perhaps a follow-up video? Thank you.
This is so cool! every piece of green could help. Besides the huge environmental benefit, it would create a positive impact on people's day to day life style for sure.
What is most exciting about a project like this is the opportunity to get creative in making new ecosystems. Experimenting with combinations of plant communities that haven't been found together in nature before.
Green roofs are more popular for us as a flat roofing business. Customers benefit not only from aesthetics, but better insulaton (and reduced energy bills) too!
My cousin in Britain just did a green roof. I wonder why people aren't getting incentives/funding for this. We need hundreds of rooftops of milkweed. I know it has been done already for one butterfly nearly knocked out from habitat loss. We have a very serious problem with accepting wildlife. All those "creepy crawlies". ☹
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.
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.
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.
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 www.purple-roof.com for ideas.
Actually, this is one of many reasons the other buildings don’t have green roofs. The structural load is more than snow because it’s a year round weight, you must account for the plants, The soil, and the water weight and maintain your designed in safety factors. Also extra precautions must be designed in for additional water leakage problems and root invasion. Plus they are expensive and difficult to keep irrigated and alive. The roof has to be intentionally designed as a green roof. Also buildings are rarely built with gravel roofs anymore anyways, the heat issues can be easily addressed with the much more standard white TPO roofing, not a green roof. It’s very disingenuous of NPR not to address the costs and challenges associated with green roofs. There are good reasons why most buildings don’t have them. The few benefits don’t always outweigh the costs. Sometimes they do, and sometimes the plants all die because of disease. If you don’t count the cost for the maintenance, the structure, the roofing, and irrigation then you are only giving lip service to a green roof and it will likely fail. Who’s more at fault the one who doesn’t build a green roof or the one who does but kills it with neglect, or the one who wastes profits that should go to payroll or better products to restore a dead green roof? Finally, a green roof does little to reduce a buildings carbon emissions or heating and cooling loads.
Thank you for sharing this with us I am from India I am desperate to know how we reduce temperature inside the building I am searching in the net for the methods I love my home town but there is 49 degree Celsius in summer so we visit only during winter's and himudity is 80 percent can I get any solution for all these situations
I read the article on disadvantages to green roofs. I just want to leave two points. As far as homes in the States, make sure you have engineered for the additional weight and that the contractor knows how to correctly build a flat roof. P.S. They aren't actually flat. The last point is more and more insurance companies are doing drone surveys and cancelling your homeowners policy if they don't like what they see. So we as a community of green citizens need to make sure we are supporting legislation that keeps this from happening.
In the Philippines, we currently experiencing an El niño phenomenon which makes the weather more hotter. I guess this could be the best way to tackle climate change.
It’s nice there are some positives to green roofs, but it’s sad that the forests are being destroyed at such a rate that green roofs are the alternative.
Trays are not really a smart option to manage stormwater. think about a sudden rain flush, and then water gathers to find a way out (dry soil will resist water initially). The 10-30 seconds that the water gathers, allows it to find the crachs in between the trays to escape. Testing in GRD Laboratories found that 50% of the water escapes this way, and that is terrible because a) the plants NEED the water, and b) it just let go of a huge amount of stormwater when it matters most, which is during massive storm events. have a look at www.greenroofdiagnostics.com (GRD) for more information, or check out www.purple-roof.com.
Lucus Kane Yes, and those savings recur every year, but how much did they have to pay upfront to set up the green roofs? And are there any regular maintenance costs? Those are the things I'm wondering about.
That's not very helpful. He wants to know how much it costs, that doesn't mean that he's cynical about it; just curious. :P A green roof costs around $15 to $20 per square foot. So, if they saved $3M per year, that means that they could implement 0.6M square foot of green roof each year. So, to cover New York with green roofs, which is 1B square foot, you'd have to invest $15B up front to make that happen. Judging by the acreage of the Javits Center, the square feet is 290.000. That means that the costs of construction were between $4.4M and $5.9M, using commercial prices. Considering the scope, though, it is probable that the project was on the cheaper end of that range. So, the project will start making return on investments in less than two years, which is a significantly short period for something to make a return on investment, in terms of most cost-saving measures like solar panels and the like. Not to mention all the other benefits. It's a no-brainer, I think.
a lot of these ideas are just concept-stage and barely scrape the surface. They are being promoted by people who dont really understand the science involved. Some real-world highly useful options include solvent-free paints eg Lakeland Paints - which are solvent-free, VOC-free, Non-toxic and actually edible ! Surely, paint solvent is a tiny concern you might think ?? Not at all - paint emitted 24 MILLION tons of greenhouse-gas solvents into the atmosphere last year and every year (WHO 180 et al) - and these solvents are on average 20-50x worse than CO2. So - if you really want to do something to help counter global warming you could do a lot worse than switch to one of the VOC-Free paints out there.
NYC government should implement a sort of tax write off or credit for the planting of the green roofs! That would convince even climate change deniers as it's simply a cost saver. Similar to California doing that for solar panels.
Yo. Um. NYC is FIVE BOROUGHS. You talk about “NYC” but leave out most of the city. Imagine talking about “America” and only including California and Nevada. That’s about what you do here.
Imagine how beautiful it would be

So if you add a green roof on a flat every floor will be cooler?
This really puts the costs for planting them in a new perspective...

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.

Except you’d have to be careful because some species are invasive. It could turn bad with the wrong plants.

Thank you to Norway for inventing the green roofs back when Vikingry started in Norway 1000's of years ago.

So we as a community of green citizens need to make sure we are supporting legislation that keeps this from happening.
Also, where possible, wetlands, porous paving to help control stormwater runoff.
So helpful, so insightful, thank you so much NPR!!
Any suggestions on plants suitable for green roof designs in Africa. Most of the plants i have discovered don't do well in arid lands
Very informational and helpful! Thank you NPR😁♥️
Knowing that the roof has a certain load limit I wonder how often they'll need to haul down the excess bio mass.
A BRILLIANT VIDEO!
Great share and way forward!
The only think I think about is the weight… like was the building built to hold all that soil, especially when it gets wet and holds in the water?
I'm not an environmentalist, but I think this is a fantastic idea
In the Philippines, we currently experiencing an El niño phenomenon which makes the weather more hotter. I guess this could be the best way to tackle climate change.
Good vidéos for school
It’s nice there are some positives to green roofs, but it’s sad that the forests are being destroyed at such a rate that green roofs are the alternative.
I wonder how much weight this would add to the roofs, and how much greenery it can handle. Would rooftops need reinforcements?
Anyone know anything about the green roof trays to contain the plants? One example is at 3:04 in the video. Pretty exciting stuff.

This video is just what I needed to propose this initiative to my city's Environment Department, is there a way I can quote it as a source?
I love green roofs! I also studied green roofs.
Can you provide the company that worked on this project?
It would really suck to deal with when the material underneath the dirt needed to be repaired. Still would be worth it though I think
really nice
Wow. That's astonishing. They saved 26% of their usual energy consumption and that's just the roof top.
Captain Planet probably is happy for this idea. 🏡
Which company made these roof projects?
Very nice!
Good initiative.
Green roofs are necessary now
Is it accessible for public ?
$3 million in savings, but how much did it cost to put into place?
Cody Griffin 3 million in 1 year
Lucus Kane Yes, and those savings recur every year, but how much did they have to pay upfront to set up the green roofs? And are there any regular maintenance costs? Those are the things I'm wondering about.
Well, they wouldn't do it if it didn't save money. So... lol?

Cody, if you're going to fixate on costs impracticalities, we're never going to save the world. Believe me, I study this at a 4 year college.

I hope this happens more and more
so cute I hope they do it
It would be great for tropical countries who receive more rainfall and sunlight
We need more green roofs. :P
