Abstract: Energy saving and carbon reduction in the field of construction are essential for China to achieve the goal of " peak carbon emissions and carbon neutrality". In order to meet decarbonization and economy of building terminal energy consumption, this paper proposed an optimal control method of electricity-hydrogen-heat double-layer energy for zero energy building system. Firstly, this paper constructed a zero energy (zero carbon) building energy topology structure containing wind-photovoltaic-hydrogen according to the energy use characteristics of the building. Secondly, the energy management of zero energy building system was divided into economic optimization layer and real-time power control layer according to different time scales. For the economic optimization layer, the electricity-hydrogen-heat economic optimization management method was proposed; for the real-time power control layer, the real-time power deviation correction strategy based on state control was proposed. Finally, the effectiveness of the proposed method was verified by simulation of a typical daily example. Also, considering the recovery and utilization of waste heat from the operation of electrolyzers and fuel cells, the overall operating efficiency of the system has increased from 72.9% to 87.5%.
