Green building means maximizing resource conservation (energy saving, land saving, water saving, material saving) throughout the life cycle of the building, protecting the environment and reducing pollution, providing people with healthy, applicable and efficient use of space, and nature. Harmonious symbiotic building. Green buildings include solutions that are more efficient, healthier and more sustainable than traditional solutions at all stages of the building's life cycle, with the same level of comfort and service.
At present, China has a construction area of more than 50 billion square meters, and a new construction of 1.6 billion to 2 billion square meters per year. More than 95% of buildings in China are high-energy buildings. If the same indoor comfort is achieved, the energy consumption per unit of building area is two to three times that of developed countries with the same climatic conditions. Energy-saving renovation of existing buildings has great potential for energy conservation and emission reduction. During the “Eleventh Five-Year Plan” period, building energy efficiency assumed 20% of all energy-saving tasks in China. If the 50% energy-saving standard is implemented and the local energy-saving standard is 65%, then 354 million tons of standard coal will be saved annually by 2020, accounting for 30.7% of the national energy-saving target. While realizing energy saving in buildings, green buildings can provide users with a comfortable and healthy indoor environment, representing the development trend of the world's buildings, and the prospects are very broad.

Identification projects, including 480 green building projects, 530 green building projects, and 312 green building signs. Following the spurt of growth in the number of green building signs in China in 2011, the number of green building signs continued to grow strongly in 2012.

The scale of construction projects in China that have obtained the green building star energy efficiency label is smaller than other countries but develops rapidly. The low level of development also means that the market space for green buildings in China is huge. At present, China's green building investment is concentrated in economically developed regions. Among them, Jiangsu, Shanghai, and Zhejiang in East China have a relatively dominant position in terms of both the number of green buildings and the size of the area, and Shanghai is the corresponding one. GDP, per capita income, and purchasing power are all in the forefront of the country. Guangdong in South China, Beijing, Tianjin and Hebei in Hubei have higher status. The green building industry in the above regions has developed rapidly and has rich experience. The government's policy on green buildings is more systematic and mature than other regions. The market demand is becoming larger and larger, and the incremental cost of green buildings is relatively small, becoming a green building investment. Hot spots.
In addition, the development level of green buildings in the central and western regions is relatively low, but it means that there is a large space for development. Once the government's policies on the development of green building industry are detailed, systematic and effective, these areas will also become green buildings. Areas with high investment potential.
