Background With the increase of global energy consumption and the increase of environmental protection consciousness, building energy efficiency optimization has become a key field in building design and management. Building operations, particularly heating, ventilation and air conditioning (HVAC), lighting systems, and other electrical equipment, tend to consume large amounts of energy during their use. In addition, the influence of the thermal performance of the building outer vertical surface and the building enclosure on the building energy efficiency is not negligible, and the traditional building enclosure generally lacks flexible adjustment capability and cannot sufficiently cope with external environment changes and internal thermal load fluctuation. Existing building energy efficiency optimization methods focus on reducing energy consumption by increasing insulation or increasing plant efficiency, however, these methods generally rely on fixed designs and parameters and cannot be dynamically adjusted according to environmental changes and actual use of the building. With the advent of intelligent building technology, optimizing building energy efficiency using real-time data monitoring and intelligent control has become a trend, but some technical challenges still remain. At present, most schemes in building energy efficiency optimization technology cannot effectively integrate multiple aspects of building design, building envelope, energy recovery, equipment scheduling and the like, and the flexibility and the real-time adjustment capability in coping with complex environmental changes are still insufficient. Furthermore, despite the research and application of energy recovery systems and adaptive materials, how to efficiently combine these technologies to achieve overall optimization of building energy efficiency remains an unsolved technical challenge. Therefore, how to optimize the energy efficiency of the building based on the factors of building structure parameters, building envelope, energy recovery system, intelligent scheduling and the like through an integrated technical scheme has become an important subject in the current research and application of the energy efficiency of the building.
