The world’s tallest skyscraper is set to start construction next month in the city of Changsha, China. Apart from being the tallest skyscraper in the world, it’s also a sustainable way to accommodate an ever-growing population.
Broad Sustainable Construction says the Sky City concept greatly reduces the per capita use of land, as well as the CO2 emissions caused from vehicles ferrying people around a normal city. A resident of this type of vertical city would be using 1/100th of land compared to a horizontal city dweller.
Apart from one of the 92 elevators in the building, walking is also an option via the six mile long ramp running from the first to the 170th floor. Alongside the ramp are 56 different 30 foot high courtyards used for basketball, tennis, swimming and other forms of entertainment – there’s even 930,000 square feet of interior vertical organic farms.
The building is also claimed to be five times more energy efficient than conventional ones, featuring insulated walls and triple glazing. Exterior shading cuts cooling requirements by 30% and the remaining cooling or heating needed comes from a co-generation plant using waste heat from power generation.
Being constructed from prefabricated panels and parts, the building will take 16,000 part time and 3,000 full time workers four months to pre-assemble, and three months to construct onsite.
