Some 17 years ago, I became allergic to Delhi's air. My doctors told me that my lung capacity had gone down to 70 percent, and it was killing me. With the help of IIT, TERI, and learnings from NASA, we discovered that there are three basic green plants, common green plants, with which we can grow all the fresh air we need indoors to keep us healthy. We've also found that you can reduce the fresh air requirements into the building, while maintaining industry indoor air-quality standards.
Pre nekih 17 godina postao sam alergičan na vazduh u Delhiju. Moji lekari su mi rekli da je kapacitet mojih pluća opao na 70% i da me to ubija. Uz pomoć IIT, TERI i istraživanjima NASA-e, otkrili smo da postoje tri osnovne lisnate biljke, obične lisnate biljke, uz pomoć kojih možemo da uzgajamo svež vazduh koji nam je potreban unutra da bismo bili zdravi. Takođe smo ustanovili da možete smanjiti potrebe za svežim vazduhom u zgradi, dok održavate standard kvaliteta vazduha u zatvorenom prostoru.
The three plants are Areca palm, Mother-in-Law's Tongue and money plant. The botanical names are in front of you. Areca palm is a plant which removes CO2 and converts it into oxygen. We need four shoulder-high plants per person, and in terms of plant care, we need to wipe the leaves every day in Delhi, and perhaps once a week in cleaner-air cities. We had to grow them in vermi manure, which is sterile, or hydroponics, and take them outdoors every three to four months. The second plant is Mother-in-law's Tongue, which is again a very common plant, and we call it a bedroom plant, because it converts CO2 into oxygen at night. And we need six to eight waist-high plants per person. The third plant is money plant, and this is again a very common plant; preferably grows in hydroponics. And this particular plant removes formaldehydes and other volatile chemicals.
Te tri biljke su Areca palma, Svekrvin jezik i Đavolji bršljan. Botanički nazivi su pred vama. Areca palma je biljka koja uklanja CO2 i pretvara ga u kiseonik. Potrebno nam je četiri biljke u visini ramena po jednoj osobi, i kad se radi o negovanju, treba da brišemo lišće svakog dana u Delhiju i možda jednom nedeljno u gradovima sa čistijim vazduhom. Moramo je đubriti organskim đubrivom, koje je sterilno, ili hidroponikom, i iznositi napolje na svaka 3-4 meseca. Druga biljka je Svekrvin jezik (sabljica), što je isto uobičajena biljka, mi je zovemo biljka za spavaću sobu, jer prerađuje CO2 u kiseonik preko noći. Potrebno nam je 6 biljaka, u visini struka, po osobi. Treća je Đavolji bršljan, koja je takođe rasprostranjena; po mogućstvu uzgajana hidroponikom. Ova biljka uklanja formaldehide i ostale isparavajuće hemikalije.
With these three plants, you can grow all the fresh air you need. In fact, you could be in a bottle with a cap on top, and you would not die at all, and you would not need any fresh air. We have tried these plants at our own building in Delhi, which is a 50,000-square-feet, 20-year-old building. And it has close to 1,200 such plants for 300 occupants. Our studies have found that there is a 42 percent probability of one's blood oxygen going up by one percent if one stays indoors in this building for 10 hours. The government of India has discovered or published a study to show that this is the healthiest building in New Delhi. And the study showed that, compared to other buildings, there is a reduced incidence of eye irritation by 52 percent, respiratory systems by 34 percent, headaches by 24 percent, lung impairment by 12 percent and asthma by nine percent. And this study has been published on September 8, 2008, and it's available on the government of India website.
Uz pomoć ove tri biljke možete uzgajati sav svež vazduh koji vam je potreban. Zapravo, mogli biste biti u flaši sa poklopcem i uopšte ne biste umrli, i ne bi vam bio potreban svež vazduh. Isprobali smo ove biljke u našoj zgradi u Delhiju, to je zgrada od 17000 kvadrata, stara 20 godina. Tu ima oko 1200 ovakvih biljaka za 300 ljudi. Naše studije su pokazale da postoji verovatnoća od 42% da se nivo kiseonika u krvi poveća za 1% ako ostanete unutra, u ovoj zgradi, 10 sati. Indijska vlada je otkrila i objavila studiju koja pokazuje da je ovo najzdravija zgrada u Nju Delhiju. Studija je pokazala i da je, u poređenju sa drugim zgradama, smanjena pojava iritacije očiju za 52%, respiratornih organa za 34%, glavobolja za 24%, oštećenja pluća za 12% i astme za 9%. Ova studija je objavljenja 8. septembra 2008. i dostupna je na sajtu indijske vlade.
Our experience points to an amazing increase in human productivity by over 20 percent by using these plants. And also a reduction in energy requirements in buildings by an outstanding 15 percent, because you need less fresh air. We are now replicating this in a 1.75-million-square-feet building, which will have 60,000 indoor plants.
Naše iskustvo pokazuje neverovatan porast produktivnosti za preko 20%, kad se koriste ove biljke. Takođe i redukciju potreba za energijom u zgradama za neverovatnih 15%, jer vam je potrebno manje svežeg vazduha. Sada ponavljamo ovo u zgradi od oko 600.000 kvadrata, koja će imati 60.000 biljaka unutra.
Why is this important? It is also important for the environment, because the world's energy requirements are expected to grow by 30 percent in the next decade. 40 percent of the world's energy is taken up by buildings currently, and 60 percent of the world's population will be living in buildings in cities with a population of over one million in the next 15 years. And there is a growing preference for living and working in air-conditioned places. "Be the change you want to see in the world," said Mahatma Gandhi. And thank you for listening. (Applause)
Zašto je ovo važno? Takođe je važno za okolinu, jer se očekuje da svetske potrebe za energijom porastu za 30% u narednoj deceniji. Zgrade trenutno troše 40% svetske energije, a 60% svetske populacije će živeti u zgradama u gradovima, što je populacija od preko milion u narednih 15 godina. Raste i preferencija za životom i radom u klimatizovanim prostorima. "Budi promena koju želiš da vidiš u svetu", rekao je Mahatma Gandi. Zahvaljujem vam na slušanju. (aplauz)
