The construction industry has ushered in the era of "carbon reduction"! A total of 8.5 billion square meters of green buildings have been built in China

The upstream and downstream carbon emissions of the construction industry account for more than half of China’s total carbon emissions. In recent years, through the development of low-energy consumption, prefabricated construction and other methods, the construction industry is also gradually reducing carbon. According to data from the Ministry of Housing and Urban-Rural Development, as of 2021, a total of 8.5 billion square meters of green buildings have been built in my country.

At present, a prefabricated building with components processed in the factory and assembled like building blocks at the construction site, standardized design and intelligent application is becoming a new representative of the industry. In Beijing, a modular prefab project is being finalized.

The reporter saw that the entire construction site was very clean and refreshing, and could not hear the noisy construction noise of ordinary construction sites. Using the prefabricated building model, the overall construction period can be completed in only 6 months, while the traditional construction method generally takes about 2 years.

Li Zhipeng, executive manager of CSCEC Beijing blue-collar apartment project: In terms of water saving, it can save more than 50% compared with traditional buildings, and in terms of land saving, it basically uses more than one-third less land than traditional buildings. At the same time, we use high-strength bolts to connect, which greatly reduces electric welding, light pollution and noise pollution.

In 2021, the proportion of newly started prefabricated buildings in the country will reach 24.5% of the new construction area. Compared with the energy saving and environmental protection of prefabricated buildings, the world's first "light storage, direct and flexible" building in Shenzhen not only saves energy, but also empowers energy. On the roof of this 400-square-meter office building, a large number of solar photovoltaic power generation devices are laid, which can not only supply power to the building itself, but also reserve excess electricity, making each building a green "power plant".

Academician of the Chinese Academy of Engineering Jiang Yi, Chairman of the China Energy Conservation Association: The more important function endowed by "light storage, direct flexibility" to the building is that it uses energy and electricity flexibly.
