By 2025, new residential buildings will fully implement the green building two star and above standards, and new public buildings will strive to fully implement the green building two star and above standards. Vigorously develop prefabricated buildings, promote green building materials, and promote the recycling of building materials. By 2025, the proportion of prefabricated buildings in new construction will reach 55%, and the proportion of green building materials application will reach 70%; By 2030, the proportion of prefabricated buildings in new construction will further increase..

By 2025, the proportion of urban green buildings in newly constructed buildings will reach 100%, and the proportion of prefabricated buildings in newly constructed construction area during the same period will reach 50%. To promote the development of new building industrialization represented by prefabricated buildings, government invested office buildings, hospitals, schools and other public buildings should fully adopt prefabricated building technology, guide industrial buildings, commercial buildings, medical buildings and public buildings to adopt steel structure systems, and promote the coordinated development of intelligent construction and building industrialization. Vigorously developing prefabricated buildings and prefabricated decoration, by 2025, prefabricated buildings will account for 50% of the newly started construction area in the same period, and prefabricated decoration buildings will account for 30% of the newly started finished housing area in the same period..

Implement green construction throughout the entire process of engineering construction, comprehensively promote energy-saving doors and windows, green building materials, accelerate the coordinated development of intelligent construction and building industrialization, vigorously develop prefabricated buildings, and promote steel structure residential buildings. Establish and improve a green and low-carbon oriented urban and rural planning and construction management mechanism, promote construction waste management and resource utilization. Strengthen the management of building demolition and eliminate large-scale demolition and construction. By 2030, prefabricated buildings will account for 50% of newly built urban buildings in that year, and the utilization rate of construction waste resources will reach 55%..

Promote green construction, encourage the adoption of BIM technology for construction, and vigorously develop prefabricated buildings. By 2030, the annual construction area of prefabricated buildings in the city will account for 50% of the new construction area. Vigorously promote the energy-saving renovation of rural housing buildings, promote the thermal insulation renovation of existing non energy-saving residential buildings in rural areas, promote the construction of light steel prefabricated buildings in rural areas, and promote modern rural housing construction technologies that are economical, beautiful, green, and energy-saving..

Lifting Eye

Improve the design and construction level of rural houses, promote prefabricated construction and renewable energy technologies, carry out the renovation of existing rural houses, and build green rural houses. Vigorously promote the application of prefabricated buildings, promote the construction of steel structure prefabricated residential buildings, and encourage schools, hospitals, and other public buildings to prioritize the use of steel structures. By 2025, positive progress will be made in the green transformation of construction methods, with prefabricated buildings accounting for 30% of the newly constructed building area. By 2030, prefabricated buildings will account for 40% of newly built urban buildings in that year, and the amount of construction waste discharged from new construction sites will not exceed 300 tons/10000 square meters. The resource utilization rate of construction waste will reach 55%. Actively introduce, digest, and absorb advanced technologies in building energy conservation, green building, and prefabricated building, and accelerate the industrialization process of prefabricated supply chain, extension chain, and strong chain by using complete sets of products and new technologies in the industrial base radiation area..

Promote the application of prefabricated technology. Steadily developing prefabricated buildings, comprehensively promoting the development of prefabricated buildings such as concrete and steel structures, and promoting steel structure residential buildings. Gradually push.
