The two towers will clean the air of Nanjing, China, with 1,100 trees and 2,500 shrubs and plants.
When Stefano Boeri Architetti presented the idea of installing a vertical forest in Milan, people were beyond thrilled with the idea. Following the success of that introduction, the architecture firm now seeks to construct similar, but in Nanjing, China.
Inhabitat reports that two towers which overlook the Nanjing Pukou District were initially expected to be completed by the end of 2018. Overflowing with 1,100 trees from 23 local species, as well as 2,500 cascading shrubs and plants, the early proposal estimated daily oxygen production at 132 pounds; that projection is not a measurement of citywide air-quality improvement. Additionally, passersby and tourists will be greeted with a breathtaking view.
The buildings, of course, will include more than just plants. The taller tower (656 feet) will hold offices, a museum, a green architecture school, and a rooftop club. And in the second tower (354 feet), a 247-room Hyatt hotel will be found, complete with a rooftop swimming pool. Shops, restaurants, and a conference hall will also be included in the second building in a podium that will rise 65 feet.

The planted façades were presented as a way to bring vegetation closer to building occupants. That design intention does not establish a measurable health benefit for hotel guests or an improvement in the surrounding city’s air.Original source
According to Stefano Boeri Architetti’s press release, there will be approximately 600 tall trees and 500 medium-sized trees, in addition to the other foliage, that will help regenerate biodiversity in the area.

The project is being celebrated because it was promoted as an early vertical-forest project for the region; the architect’s later account identifies Nanjing as its second completed Vertical Forest in China. Investors are also satisfied with the fact that the conceptualized idea will further modernization efforts in the south of China’s Jiangsu province. Because of the potential economic boost the towers will provide, Nanjing Yang Zi State-owned Investment Group Company Limited is promoting the project.

The 2017 announcement also described the architecture firm’s intention to build more green towers in Shanghai, Guizhou, Shijiazhuang, Liuzhou, and Chongqing.

The planting is a continuing responsibility
This article records an early proposal, including an anticipated 2018 completion date and an initial planting specification. Later material from Stefano Boeri Architetti describes a different tree count and identifies Nanjing as the studio’s second completed Vertical Forest in China, following Huanggang. Those changes matter: an early rendering and press release are not a permanent specification of the finished building. The 2017 figures are useful for understanding the design’s development, provided they remain clearly attributed to the announcement rather than presented as present-day measurements.
What would demonstrate a greener building?
Balcony planting changes both the appearance of a tower and the work required to maintain it. Irrigation, soil, pruning and replacement belong to the design’s operation, alongside the visible trees. Environmental claims then need defined measurements: projected oxygen production is not the same as demonstrated citywide air-quality improvement. The dated Stefano Boeri Architetti’s Nanjing project page provides a route to the architect’s account, which should be distinguished from independent performance evidence.
Maintaining the trees over time
An early rendering can make foliage appear fully established from the outset. A completed building develops through planting, growth and maintenance, so photographs from different dates may show different conditions without contradicting the basic concept. Reading the project as a timeline gives those changes meaning. It also prevents an initial species count or completion forecast from becoming a permanent description of the finished towers.
