Solar radiation impacts on the building energy consumption in terms of heat and light.

I am employing a CFD software to study the temperature on each wall of a building model. It takes into account incoming solar radiation as well, providing surface temperatures through a global energy balance. I can, therefore, use EnergyPlus actuators on each wall to override the surface temperature.

The question is: if I impose the temperature on each surface, do I override the solar heat contribution? Does the sun impact in any other way in terms of heat gain?
