1. Promote green building and energy-saving technology: Under the background of double-carbon target, the construction industry can reduce building energy consumption and carbon emissions by adopting technical means such as energy-saving building design, renewable energy utilization and intelligent building.

2. Promote prefabricated buildings: prefabricated buildings have the advantages of low carbon, environmental protection and high efficiency. Through factory production and on-site assembly, construction waste and construction pollution can be reduced.

3. Develop green building materials: Encourage the use of green building materials with renewable resources, low energy consumption and low pollution, and improve building quality and environmental protection performance.
