[EnergyPlus_Support] SHGC and solar transmittance

["lorenzomattarolo" <lorenzomattarolo@xxxxxxxx>]

Hi,
I'm simulating a zone with a glass facade.
I want to have 0.15 for the SHGC of the window:

I run two simulation

1st case: window with SHGC=0,15
                      solarTransmittanceNormIncidence=0,06

2nd case: window with SHGC=0,15
                      solarTransmittanceNormIncidence=0,10


Basically the amount of solar heat entering in the zone is the same
(since the SHGC is the same), but the amount of solar radiation
(beam+diffuse) is different.
Does Energy Plus make any difference for calculating the cooling rate?
In order to estimate the cooling peak value, which case should i consider?

Many thanks,

Lorenzo
