Green livingspace

Kamal Meattle előadása növényültetéssel friss leevegőért:

a TED website-ról: ˙(

"How do we know this works?

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.

Our experience points to an amazing increase in human productivity resulting from using these plants to be >20%, and energy costs to reduce by an extraordinary >15%.

Az előadást fenntartással kezelem, de az biztos, hogy minden, ami növény az jó. Ma beszereztem a tesztnövényeimet a Columbia Road Flowermarket-en. Na jó, még hozzánk költözött egy datolyapálma és két orchidea is, de hogy is tudtam volna ellenállni???? A futó meg már május óta itt lakik, hála nagymamaámnak a friss bujtásért. Mindig is szerettem az élő ajándékokat.
