At the same time, the northern region is rich in clean energy. In response to General Xi Jinping’s proposal that “it is good to be gas, electricity should be electricity, and clean energy should be used as much as possible”, it is imperative to promote clean and warm winter in the northern region. In order to improve the heating efficiency and economy of clean energy, a combined energy-saving building component combining electric heating and phase change thermal storage structure is designed. The building envelope structure combines low-temperature phase change heat storage materials such as paraffin microcapsules and Reinforced heat transfer materials such as foam metal. The thermal performance of the phase change thermal storage structure was simulated by Fluent software. The experimental results were tested with the simulation results. The experimental study on the storage and release process of composite phase change materials such as copper foam/paraffin microcapsules was carried out. Parameter data. Experiments show that the combination of “peak and valley electricity price” and building envelope structure heat storage has a good energy-saving effect and
