Perhaps the most famous name in green architecture, architect Stefano Boeri has set his sights on a new market: Asia. The renowned designer of Milan’s Bosco Verticale will bring a similar project to the eastern Chinese city of Nanjing.
Given growing concerns over air quality in China, Boeri’s creation serves a particularly practical purpose in Nanjing’s densely populated Pukou district. The idea is simple: The two greenery-laden towers absorb ambient carbon dioxide while simultaneously introducing oxygen into the surrounding air. Preliminary estimates suggest that the building will be able to absorb some 25 tons of CO2 each year and generate 60 kilograms of oxygen per day. This is all thanks to the 1,100 trees and 2,500 hanging plants affixed to each tower’s façade.
The buildings, which will be the first of their kind in Asia, are mixed-use in every sense. The smaller of the two is already designated as a Hyatt hotel, while the larger is set to house a museum, a rooftop club, and even an architecture school dedicated to sustainable design. Slated for completion in 2018, the project will serve as a prototype for Boeri’s designs in other pollution-threatened Chinese cities.
The Forest City
Boeri’s ultimate goal is to create an entire Forest City that will become a reality in Liuzhou by 2020.
The Master Plan by Stefano Boeri Architetti for a new green city that fights air pollution is now under construction in China. The Liuzhou Forest City is commissioned by Liuzhou Municipality Urban Planning.
A city where offices, houses, hotels, hospitals and schools are entirely covered by plants and trees.
Once completed, the new city will host 30,000 people, absorb almost 10,000 tons of CO2 and 57 tons of pollutants per year and produce approximately 900 tons of oxygen.
Liuzhou Forest City will be built in the north of Liuzhou, in the mountain area of Guangxi, in the southern part of China; in an area that covers 175 hectares along the Liujiang river.
The new green city, entirely wired, will be connected to Liuzhou through a fast rail line used by electric cars and will host various residential areas, commercial and recreational spaces, two schools and a hospital.
Liuzhou Forest City will have all the characteristics of an energy self-sufficient urban establishment: geothermal energy for interior air-conditioning and solar panels over the roofs for collecting renewable energy.
The great innovation of Stefano Boeri Architetti’s project is the presence of plants and trees over every building, of all sizes and functions.
Liuzhou Forest City will host in total 40,000 trees and almost 1 million plants of over 100 species. The diffusion of plants, not only in the parks and gardens or along the streets, but also over building facades, will allow the energy self-sufficient city to contribute to improve the air quality (absorbing both CO2 and fine dust of 57 tons per year), to decrease the average air temperature, to create noise barriers and to improve the biodiversity of living species, generating the habitat for birds, insects and small animals that inhabit the Liuzhou territory.
For the first time in China and in the world, an innovative urban settlement will combine the challenge for energy self-sufficiency and for the use of renewable energy with the challenge to increase biodiversity and to effectively reduce air pollution in urban areas – which is really critical for present-day China – thanks to the multiplication of vegetable and biological urban surfaces.
