In the face of the challenges posed by global climate change, the construction industry is under immense pressure to transform, with a consensus emerging on the need for more energy-efficient construction methods. Prefabricated buildings, renowned for their green, environmentally friendly, and efficient characteristics, are gradually becoming the new darling of the construction industry. The multi-storey prefabricated faç ade, as a crucial component of prefabricated buildings, has attracted widespread attention due to its impact on indoor thermal stability. Through systematic research on multi-storey prefabricated faç ade structures, a theoretical basis can be provided for improving the design of prefabricated buildings and enhancing their indoor thermal comfort. Indoor thermal stability is closely related to energy consumption and directly affects the comfort and health of occupants. In prefabricated buildings, factors such as facade structure design, material selection, and assembly methods play a critical role in influencing the stability of the indoor thermal environment. Studying the impact of multi-storey prefabricated faç ade structures on indoor thermal stability aims to reveal the effects of different design solutions on temperature control, guiding the future design and construction of prefabricated buildings to achieve greater energy efficiency and livability.
