Abstract

As an efficient and environmentally-friendly construction method, the space optimization and building performance improvement of prefabricated housing are the key factors affecting its popularization and application. This paper discusses the strategies of space optimization in the design of prefabricated houses, including modular and standardized design, variable and adaptive space design, composite function and integrated design, and refined size and ergonomic design. At the same time, the paper analyzes the methods to improve building performance through design optimization, material selection and system integration, including structural performance and safety improvement, energy saving and environmental protection performance improvement, indoor environment quality improvement, intelligent operation and maintenance and long-term performance improvement. Finally, through empirical research, this paper compares and analyzes the performance improvement in space efficiency, energy-saving effect and indoor environment between the assembled residence with optimized design scheme and the traditional design residence, and verifies the effectiveness of the strategy of space optimization and building performance improvement.
