Nantong, East China's Jiangsu province, has in recent years been ramping up efforts in terms of green and low-carbon development.

Since 2016, 97.45 million square meters of green buildings have been built in the city.

New buildings in the city's Chongchuan district are primarily three-star green buildings, the highest rating in the Green Building Evaluation Criteria in China.

One such building is the Nantong Grand Theater, which has a special design that allows it to reduce electricity usage by 335,000 kwh per year and carbon dioxide emissions by 11,783.6 metric tons during its lifecycle. 

The A1 and A2 land projects of the Nantong GE World in Chongchuan district have also been listed as super-low-energy architectures, which refer to those whose energy consumption is less than 50 percent of conventional ones based on national standards.

Nantong GE World is the first low-energy architecture in Chongchuan.

Nantong has also been focusing on the green reconstruction of old communities and existing public buildings, according to Ji Haidong, director of the Green Building and Technology Department of the Nantong Municipal Bureau of Housing and Urban-Rural Development.

Nantong's four administrative areas have won provincial recognition for green and low-carbon development.
