I did a model in openstudio in order to calculate HVAC cooling loads. I compared e+ results with trace700. I found that e+ has very low cooling loads. I checked the componens zising summary in e+ and found that the Fenestration solar load is very low (1/3 of the one in Trace700). I have the same U value and SHGC in both softwars. I expected to have some discrepancies in my calculations but not 3 times.
