Stefano Boeri Architetti towers are bringing the vertical garden/forest to the next level – this concept is popularized in Milan to Nanjing, China with the Nanjing Towers. The two green towers could provide the city with a breath of fresh air, producing around 132 pounds of oxygen every day as they absorb carbon dioxide.
They will accomplish this air-cleaning feat with 1,100 flourishing trees from 23 local species and 2,500 cascading shrubs and plants. The two towers at 656 feet and 345 feet tall will rise above the Nanjing Pukou District, which Stefano Boero’s press release describes as an area that will likely lead modernization efforts in the south of China’s Jiangsu province and help develop a Yangtze River economic zone.
Nanjing Yang Zi State-owned Investment Group Company Limited is promoting the towers and is listed by Stefano Boeri as an investor in the project.
The taller tower will hold offices, a museum, a green architecture school, and a rooftop club. The second tower will host a 247-room Hyatt hotel and rooftop swimming pool. A podium 65 feet high will include shops, restaurants, and a conference hall. Balconies on the buildings will allow inhabitants to get up close to the nature thriving on the building facades.
600 tall trees and 500 medium-sized trees will grow on the towers, and Stefano Boeri says the trees and cascading plants will help regenerate biodiversity in the area.
Here are some calculations – One person needs ~550liters of Oxygen per day (density 1.429g/liter at stp)
7.5M people live in Nanjing – so we would need just 100,000 of those towers (no animals included).
