Abstract: This article focuses on exploring the collaborative control technology of electrical equipment in intelligent buildings to enhance building energy efficiency and reduce energy waste. In the research, measures such as standardization of multi-device information collection, design of control algorithms, and compatibility processing were employed to achieve integrated management and optimal allocation of systems like lighting, air conditioning, power distribution, and energy storage. By constructing collaborative control technology, protocol differences among various devices were eliminated, enabling the coordinated operation of all systems. And apply intelligent control algorithms to optimize the energy efficiency of building electrical equipment and reduce unnecessary energy loss. Research results show that collaborative control technology can significantly enhance the overall energy efficiency of buildings, reduce operating costs, and simultaneously optimize the stability and economic performance of the system. By implementing optimized scheduling for various electrical equipment, it can achieve efficient utilization of building energy, providing solid technical support and theoretical basis for the implementation and application of collaborative control systems for intelligent building electrical.
