Since the energy crisis in the 1970s, countries around the world have been focusing on how to reduce energy consumption. Among them, building energy consumption plays an important role in reducing consumption, involving aspects such as the production and transportation of building materials, and the construction and operation of buildings. It is estimated that the energy consumed by buildings accounts for about 50% of the total global energy consumption, and the pollution caused by buildings accounts for more than 30% of the total global pollution. Ecological buildings (green buildings) refer to buildings that save energy, do not affect the ecological environment, contribute to the harmonious coexistence of humans and nature, and are sustainable. They emphasize design from a micro perspective, and have strong adaptability, operability, and expandability.
