Does anybody know which output shows the solar gains and the transmission losses of my building in EnergyPlus?

I want to compare the results of TRNSYS and EnergyPlus with each other. For that I need a energy balance. I found all the important outputs except solar gains and transmission losses. I would highly appreciate your help.

Kind regards,

Hey Arne, I'm also searching for the output for various building components through which transmission losses occur please let me know if you have found the correct output.

Kind regards,

See posted answer by @shorowit. All report variables are in the rdd after a simulation. Make sure you add Output:VariableDictionary, IDF; to your E+ input file so that the rdd file is created.

Look at the .rdd file after doing an EnergyPlus run to see all possible outputs that you can report. Search that file for "window" and you'll see many outputs related to solar gains and transmitted radiation. You can either report outputs on the zone level (i.e., all windows in the zone) or for individual windows. See the EnergyPlus Input Output Reference documentation for a description of these outputs to understand what they are reporting.
