- The modular assembly and rapid construction can shorten the construction cycle, reducing the energy and materials consumed in the process;
- The reasonable passive building space design can improve the comfort level of the environment within the building space, indirectly reducing energy consumption;
- A dynamic balance between energy acquisition and consumption can be achieved by improving active energy acquisition through techniques such as solar energy; and
- The smart building control can reduce energy waste by more rationally and effectively regulating the daily operation of the entire building system based on different times and use modes.
