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.
Prije kojih 17 godina, Postao sam alergičan na zrak Delhija. Moji doktori su rekli kako se kapacitet mojih pluća smanjio na 70%, i kako me to ubija. Uz pomoć IIT-a (Indian Institute of Technology), TERI (The Energy and Resources Institute), i učeći od NASA-e, otkrili smo kako postoje tri osnovne lisnate biljke, obične zelene biljke, s kojima možete uzgojiti sviježi zrak koji nam je potreban u unutrašnjosti kako bi ostali zdravi. Također smo otkrili da možete smanjiti potrebe za sviježim zrakom u zgradama, a ipak zadržati industrijski standard kvalitete zraka u prostorijama.
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.
Tri biljke su:palma Areca , Sabljica (ili Svekrvin jezik) i Đavolji bršljan. Botanička imena su ispred vas. Palma Areca je biljka koja uklanja CO2 i pretvara ga u kisik. Potrebne su nam četiri biljke do visine ramena po jednoj osobi, a što se tiče brige o biljkama, moramo brisati lišće svaki dan u Delhiju, a možda samo jednom tjedno u gradovima sa čišćim zrakom. Morali smo ih održavati organskim gnojivom, koje je sterilno, ili hidroponima, i iznositi van svaka tri do četiri mjeseca. Druga biljka je Sabljica ili Svekrvin jezik, koja je također prilično uobičajena biljka, i mi je nazivamo biljka za spavaću sobu, jer pretvara CO2 u kisik preko noći. I treba sam 6-8 do struka visokih biljaka po osobi. Treća biljka je Đavolji bršljen, i to je prilično uobičajena biljka; po mogućnosti uzgajana u hidroponima. A ova posebna biljka uklanja formaldehide i ostale štetne kemikalije.
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.
S te tri biljke, možete uzgojiti sav svježi zrak koji vam je potreban. U stvari, mogli biste biti u boci sa čepom na vrhu, i ne biste umrli, i ne bi vam bio potreban svježi zrak. Mi smo iskušali te biljke u našoj vlastitoj zgradi u Delhiju, koja ima površinu 4,645 m2 i 20 godina stara. U njoj je blizu 1,200 ovakvih biljaka za 300 stanara. Naša istraživanja su otkrila kako postoji 42% vjerojatnosti da se razina kisika u krvi poveća za 1% ako ostanete unutar te zgrade 10 sati. Vlada Indije je otkrila i publicirala istraživanje kako bi pokazala kako je to najzdravija zgrada u New Delhiju. I istraživanje je pokazalo kako je, u usporedbi s drugim zgradama, smanjena pojava iritacije očiju za 52%, problema s dišnim organima za 34%, glavobolja za 24%, problema s plućima za 12% i astme za 9%. To je istraživanje objavljeno 8. rujna 2008., i dostupno je na web stranicama 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 upućuje na nevjerojatano povećanje ljudske produktivnosti i to preko 20% kada se koriste te biljke. Također se smanjuje upotreba energije u zgradi za izvanrednih 15%, jer trebate manje svježeg zraka. Sada pokušavamo primjeniti istu stvar na zgradu od 162,580 m2, koja će imati 60,000 ovih biljaka.
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 to toliko važno? Važno je i zbog okoliša, jer se očekuje da potrebe za energijom u svijetu rastu za 30% u slijedećem desetljeću. 40% svjetske energije se trenutno koristi za građevine, a 60% svjetske populacije živjeti će u zgradama u gradovima s više od milijun stanovnika u sljedećih 15 godina. Raste i želja za življenjem i radom u klimatiziranim prostorima. "Budite promjena koju želite vidjeti u svijetu.", rekao je Mahatma Gandhi. Hvala vam što ste me saslušali. (Pljesak)
