The paper analyzes the influence of solar radiation load for energy-saving building in winter, considering the thermal inertia of building envelope, a mathematical model of unsteady heat transfer is established, and a program is compiled to calculate the dynamic solar radiation load of building envelope in winter, which is a very practical calculation of solar radiation dynamic load. It not only changes the current situation that the calculation of solar radiation load in winter for energy-saving buildings can only use the steady-state algorithm, but also provides scientific and reliable data support for thermal comfort and the dynamic analysis of heating energy consumption for energy-saving buildings.
