Zone Sensible Heat Gain Without HVAC System

Hello everyone, Is it possible for E+ to calculate zone sensible heat gain from the construction alone without HVAC system. If possible which output should I request? Right Now I can only request: Surface Average Face Conduction Heat Gain Rate [W] . My objective is to find Max air flow rate to use in the HVAC Template:IdealLoadAirSystem image descriptionThanks in advance. Here is my model https://drive.google.com/drive/folder...

@Thit are you trying to find the peak sensible heat gain from the envelope on a heating/cooling design day, or over the annual simulation? I ask because there are different summary report and output variable options that could be used.

@Aaron Boranian yes sir, I was looking for my envelope peak sensible heat gain during design day Apri 1st 2023. And I'd like to run for a whole year too if I understand for 1day period.

Technically I think you would want the convective heat transfer from the zone surfaces, not the conductive heat transfer. Convection is what contributes to the zone air heat balance, conduction is through the envelope and affects the surface inside face temperature (which is used in the convection calculation).
