Re: [EnergyPlus_Support] E+ Solar Radiation Model
It uses many weather files -- not just based on TMY3.
These weather files include Solar Radiation values.
As shown in the Auxiliary Programs document, EnergyPlus uses the Direct
Normal and Diffuse horizontal values FROM the weather file. It does
not use Global Horizontal.
For Design Days, it depends on which Solar model the user chooses in the

sky model ?
