How to Grow Your Own Fresh Air – TED 2009
This page is an extension of the talk presented at:
Index: The Discovery | The Plants | The Proof | Buildings & Climate Change | The Future
The Discovery:
A conservation community working to reduce the impact of buildings on the environment.
- Works well in the day time
- Great for living areas
- One needs about 4 shoulder high plants/person
- Needs to be put outdoors once every 3-4 months
- The leaves of the plant need to be wiped everyday in Delhi and perhaps once a month in a cleaner city
- The soil used should be of vermi manure or use hydroponics
- Converts CO2 into O2 at night
- One requires about 6-8 such waist high plants per person in the bedroom
- Leaves need to be wiped in the same way as the Areca Palm
- The soil used should be of vermi manure or use hydroponics
- Excellent for removing Formaldehyde and other VOC’s
- Best grown using hydroponics
We have tried and tested these plants for 15 years at Paharpur Business Centre and Software Technology Incubator Park (PBC™ – STIP) in New Delhi, India. It is a 20 year old, 50,000 ft2 building, with over 1,200 plants for 300 building occupants.
PBC™ – STIP is rated the healthiest building in Delhi by the Government of India.* Their study found that there is a 42% probability of increasing blood oxygen by 1% if one is inside the building for 10 hours.
Also, compared to other buildings in Delhi, the incidence of eye irritation reduced by 52%, lower respiratory symptoms by 34%, headaches by 24%, upper respiratory symptoms by 20%, lung impairment by 10-12% and Asthma by 9%. As a result of fewer sick days — employee productivity also increased.
* Study published on September 8, 2008 by The Govt. of India, Central Pollution Control Board and Chittaranjan National Cancer Institute, Kolkata, India
We conducted another experiment and sealed all fresh air and exhaust from the building for 6 weeks and found that that the air quality inside the building was better than outdoors.
We saved over 15% in energy costs as we did not have to inject 15-20 cfm of fresh air in to the building as suggested by ASHRAE – an industry standard.
You can check on today’s indoor air quality at http://www.pbcnet.com
- World energy demand is expected to grow by 30% in the next decade.
- Buildings consume 40% of the world’s energy.*
- In another 15 years, more than 60% of the world’s population will be living in cities of over 1 million inhabitants.
- There is a growing trend of having air-conditioned living and working areas, resulting in the increased need for fresh air which needs to be heated or cooled.
- ASHRAE rules require 15-20 cfm of fresh air per person for a healthy non-smoking building.
By reducing the supply of external fresh air, we achieve significant reduction in energy needed for heating and cooling buildings.

We’re now replicating this concept in a much larger 1.75 million ft2 building. We intend to use over 60,000 indoor plants!

* Sansevieria trifasciata
* Epipremnum aureum

Money plant is money plant.
Sounds promising, There use to be some building completely covered with plants from outside.. how about doing the same thing from inside.

Jason,
According to the ASPCA:
Areca palm (Non-Toxic to Cats, Non-Toxic to Dogs)
http://www.aspca.org/pet-care/poison-control/plants/areca-palm.html
Mother-in-Law’s Tongue (Toxic to Cats, Toxic to Dogs)
http://www.aspca.org/pet-care/poison-control/plants/golden_birds_nest.html
Money Plant (Toxic to Cats, Toxic to Dogs)
http://www.aspca.org/pet-care/poison-control/plants/devils_ivy.html
Both the mother-in-law’s tongue and money plant have oxalates in their leaves which is what’s toxic to cats. Sadly I have accidentally poisoned one of my cats twice with plants (2 different plants, the latter of which was on a “safe for cats” list somewhere). Even a few little bites on the plant can cause problems.
It is very painful for the animal for 24-72 hours, starts within 3 hours of ingestion, and can be fatal. More here if you care: http://www.wrongdiagnosis.com/p/plant_poisoning_calcium_oxalate_crystals/basics.htm
Seriously be very careful with these plants if you have cats as this toxicity is no joke.

There is one problem with this “health” tip; a couple living in a flat will need 22 plants (12 in the bedroom alone), and a family of 5 will need 55 plants throughout the house.
Not very practical!
that number is a survival #
like he said you could live in a bottle with them and be alright

So, the article recommends 11+ plants per person, but the test building only had four plants per person. Why the difference? It would seem that while 11+ plants is optimal, four plants per person will still provide the drastic improvement seen in that building.
Maybe because you don’t sleep at you workplace. You don’t need as much when the building is only fully used during business hours.

I’ve always been a fan of TED and even got the App on my iPhone. This is such a wonderful article and excellent way to reduce global warming and energy consumption. I’ve heard of Vertical Farming where several floors of a high rise building do something like this, but they also grow their own food for their own cafeteria. We need to return to a more balanced and self sustaining ecosystem. I also agree that the driving force behind this is economical. People and business will change their lifestyle if there is a financial incentive to do so.
Keep up the great articles TED!

To ‘Confused’
The ‘Money Plant’ is a Pothos as you guessed. Pothos is it’s old genus but it’s now been moved to Epipremnum. That is the problem with common names like money plant- everyone has a different unrelated plant they call money plant. But yeah, I would call it Pothos. Not a big fan of this plant since it looks kind of plastic, but it does grow easily in low light!
There is nothing that special about the Mother in Law’s Tongue (MILT) that it works at night, it just has a form of photosynthesis called CAM used by many dry-adapted and succulent plants like cacti, kalanchoe (much softer than MILT and has nice flowers), jade, hen & chicken, and anything with the genus Crassula.
Dracena marginata or the dragon plant is supposed to help clean some toxins out of the air as well and are very easy to grow. Kind of look like Dr. Seuss plants.

Do I really need 4 bedroom plants to filter the air in my room? One or two is possible te setup somewhere but 4?
TyKH, the quantities specified assume that there is zero external fresh air (i.e. you’re sealed in your room), and that you’re in Delhi where pollution levels are high. You can probably do with fewer.
Love it, but the volume of plants required could seriously cramp a lot of living spaces. Is there any research being done to locate more compact plants with the same output so that those of us with out room for 8 potted plants in our bedroom can reap the benefits?

The number of plants required per person, plus the maintenance (”wipe the leaves every day”), make this unmanageable. Why not grow some kind of aerobic Algae in large jars or an aquarium tank — and pump ambient air through the mix — to yield a larger output of O2 in a smaller space? Similarly, some bacteria are able to decompose toxic substances, and thus might take the part of the money plant. The question is, which is more efficient: growing so many plants; or, growing some other organism which might have a greater output and larger surface area to take up CO2 and toxins while releasing O2 for humans?
it stated above that only in delhi u need to wipe the leaves everyday, but only about once a month in cleaner cities… most buildings in delhi does is open and does not have air-condition, whereas in more developed cities the air is cleaner, and cleaner air probably because most buildings are closed and air-conditioned.
wiping the leaves does not mean a thorough squeaky clean type of clean, but a simple wipe will suffice… there are cleaners in all buildings anyways, like janitors, maintenance, etc, and they sweep the floor, vacuum, clear up rubbish, wipe toilets clean every single day, and usually done after office hours.. it has been done and it is very practical. its the same situation as having to wipe clean the toilet seat, and every hour or so at that.
the opportunity cost is against savings towards air conditioning, and better health output, while there is no additional electrical costs as compared to requiring pumps to go through the algae in jars and aquariums…
and not to mention to psychological effects of having greens in buildings…

This is a home run, nice piece of information. I also have a column as “The Green Wall Editor”. I lecture on the use of vegetated green walls. My latest column is about the use of vegetation indoors to clean the air….in short if you utilize 6 – 18″ potted plants you will be using roughly 35 square feet (3.25 m), this is valuable living, retail or office space and it too may hinder a doorway and foyer. We have utilized our green wall system to introduce the same plant material to a vertical system. Our Green Living Wall, unlike the potted plants, will allow for a true 35 sf of green space / plants, in comparison to the potted plants that have voids between the pots. The walls actually provide more usable green space for less cost and without giving up that valuable floor space. Also gander at the walls that we are growing edible crops…utilizing two concepts of clean air and food production….I can be emailed directly at george@agreenroof.com

I am in Canada and really all I’m trying to find out is how I can possibly (economically) purchase these plants for use in my office or for other peoples offices. I am even having a hard time finding where to buy all three of the plants… I can usually only find 1 or 2, but they look like they are costing 100+$ per plant!! Please let me know because I would like these in my house, office, and company. Thanks
I feel that this kind of discoveries are wonderful examples of how the honest research, willingness and sensitivity can make the difference to improve the quality of our lives now and in the future.
I have two questions:
The amount of plants depends on the volume of air to be cleaned or the number of persons using it or how polluted is the air and what kind of pollutants we detect in an specific volume of air? I think these three factors has to be considered to decide how many plants should we use. Do you have any methodological way to determine it in a more exact way?
I am a spanish speaking person leaving in Mexico City. Can I find the species of plants here and which are their names in Mexico (or Latinamerica, not Spain)?
Anyway, congratulations, people like you can really impact our global future.
I have one question about having plants inside the house. Isn’t it true that plants give out CO2 at night and if this is the case, isn’t it a bad idea to have plants inside the house?
No denying, during the day, when the plants exhale oxygen, it improves the oxygen in the house. But what about during the night?
Or is it so that these three plants listed in here, are exceptions in that they don’t breathe out CO2 at night?

[...] These are the plants that were used in the Paharpur Business Centre in Delhi where much of the research regarding these ‘ indoor fresh air’ experiments has taken place, however, there are other plants which are equally as useful. Even though I’ve found it easy to source money plants and mother in law’s tongues I’ve found it much harder to find the areca palms, and so have opted for different types of palm in the short-term. You also don’t need to go out and buy a load of plants in anycase, you can start by asking for cuttings off friends and family members and gradually start to build up your collection. Other good plants are ivy plants, which offset benzene (so useful to keep in kitchens), chrysanthemum flowers to absorb formaldehyde and benzene, spider plants and corn plants to absorb formaldehyde, and azaleas, dracaenas, Chinese evergreens, gerbera daisies, bamboo palms, dieffenbachias and peace lillies are all going to improve the air quality and natural beauty of your home.

Very interesting! We need more fresh air!
We need this kind of fresh air action in Detroit.
Of course, a neighbor may steal it
It says:
“The soil used should be of vermi manure or use hydroponics”
“Best grown using hydroponics”
Why? What would be the advantage of vermi manure or hydroponics over ordinary soil?
However I see two big problems:
1. How do you take care of 6000 plants? Watering is one thing, it could maybe even be done automatically or maybe twice a week.
Cleaning the leaves is the next thing. If it takes 4 minutes per plant, one worker will be occupied for 16.6 days – walking time between plants and breaks not included.
And then they have to be cut back, cleaned, repotted..
2. What about light needs? Energy savings are great. However, plants need light to grow. You could plaster all windows but then you need artificial light inside, esp. for workplaces. Or you place the plants further back in the room, then you maybe need artificial light for each plant. I wonder if this still saves energy then, and which solution is better- plants at the window or back in the room.
At least plants look nice and cheer you up. That alone is worth most of it I think.
I read somewhere that indoor plants won’t really make a difference since air flows in and out without any problems. By that I mean there won’t necessarily be more oxygen indoors if you have these indoor plans. However, being a plant lover myself, just knowing that I’m helping reduce CO2 in the atmosphere is well worth it. I’ll look for these plants and place them by the window. I won’t necessarily follow the prescribed ratios since they won’t fit in my room.
