When adding output variables to my results I received a following error statement in the .err file:

"* Warning * The following Report Variables were requested but not generated because IDF did not contain these elements or misspelled variable name -- check .rdd file

*** Key=*, VarName=DIRECT SOLAR RADIATION RATE PER AREA, Frequency=Hourly

*** Key=*, VarName=DIFFUSE SOLAR RADIATION RATE PER AREA, Frequency=Hourly"

The data are needed to verify the proper use and calculation of the direct normal radiation in the modified .epw file (using a local weather station data).

Please tag the application you use. Probably e+

I think that both of the variables are missing the prefix site. So it should read

Site Diffuse Solar Radiation Rate per Area
Site Direct Solar Radiation Rate per Area

But you really should be checking the eplusout.rdd file ( one of the outputs from running the simulation) to find out which variables are available in your model.

"Site" helped. Thank you!
