How does EnergyPlus weight incoming solar radiation?

I thought the sun angle projection was automatically applied in the EPW file, meaning that the radiation data are already zeroed out during night and vary during the day, according to the corresponding latitude and day of the year. However, I am making some tests and this is not what happens. I am running 2 simulations with the same building model and the same EPW file, except I am using 2 different latitudes in the header of the EPW files. The output heating loads in the 2 cases are different.

Does EnergyPlus apply any other weight depending on the sun angle?
