The reason why prefabricated houses and modular buildings are so popular is mainly due to their high efficiency, environmental protection, and energy saving. These building models adopt factory production and on-site assembly methods, which not only greatly shortens the construction period and reduces labor costs, but also reduces the generation of construction waste, and effectively improves the utilization rate of resources. In addition, modular buildings pay more attention to energy conservation and environmental protection in structural design and material selection, so that buildings can significantly reduce energy consumption and carbon emissions during operation, which is in line with the current global climate change response strategy.
