Dear Kim,
I'm not sure if I understand what you need. However, if you are looking for
"Global Horizontal Radiation" for a simulation, EnergyPlus does not currently
use that value according to the E+ Weather Converter Program documentation. You
could enter 9999 for each timestep.
If you are looking to calculate "Horizontal Infrared Ratiation from Sky", Brent
Griffith from NREL pointed me toward Appendix E in this report:

Good luck.
Holly

Dear Mark,
Thanks for your reply.
I made an algorithm that screens diffuse & beam radiation from global radiation
under clear sky condition
(reference book: solar engineering of thermal processes).
But I can't find the contents about prediction of solar radiation.
What I want to know is how can I "forecast" global radiation in future time
(1,2,3..hour or 1,2,3...day later).
Thanks in advance.

Can anyone help me with an eQuest Weather File conversion error?
When using the eQuest Weather Format Convertor and selecting the
File_IWEC.epw weather file in the eQuest weather folder in my c drive and
clicking "Convert" I get an error saying "Invalid Filename"
Anyone seen this before?
