According to ABC News on the 11th, China’s Yuanda Construction Company completed a 57-story skyscraper in just 19 days.
The company constructed the high-rise in Changsha at a remarkable pace of three floors per day. Named “Xiaotian City,” this building was topped out on February 17th. It stands over 200 meters tall with a total construction area of 180,000 square meters. The complex features a 3.6-kilometer pedestrian street, 19 halls each 10 meters high, office spaces accommodating 4,000 people, and 800 residential units.
- Reduces the need for 15,000 concrete transport vehicles
- Eliminates dust pollution
The air quality inside the building is 100 times cleaner than outside. All indoor air is sourced from outside, ensuring no cross-contamination. The building features a PM2.5 filtration system with 99.9% efficiency.
Additional features include:
- 20 cm external wall insulation
- Four-story glass windows
- Fresh air heat recovery systems
- Combined Cooling, Heating, and Power (CCHP) technology
The building achieves 80% energy savings, reducing annual CO2 emissions by approximately 12,000 tons and PM2.5 emissions by about 46 tons.
The environmental impact of this project is equivalent to planting 660,000 trees.
Constructing three floors per day, this project embodies the future of rapid prefabricated building methods.
Transitioning from extensive development to sustainable development marks China’s new normal.
