The calculation of the heat transfer coefficient of composite EPS formwork recycled concrete shear wall was studied.According to the thermal conduction mechanism of reinforced concrete and EPS template, the calculation expression of the relationship between thermal conductivity and temperature and humidity of each material was obtained, Heat transfer coefficient correction calculation method in actual working environment.Analysis and comparison of the heat transfer coefficient test value, literature reference value and correction calculation value of four specimens showed that the correction calculation method can more accurately reflect the true value of the heat transfer coefficient as The detailed design of building energy-saving provides the theoretical basis.The heat transfer coefficient correction calculation method is used to calculate and analyze the heat transfer coefficient of composite EPS formwork shear wall suitable for the climate conditions in Beijing, and compared with the reference value of the literature, the results It shows that it is more reasonable to adopt the modified calculation method to save energy.
