Conversion of solar radiation for maximum heat load

Checking the effect of solar radiation on maximum heat load. This model is just a simple box with a small window.

Comparing the "Zone Windows Total Heat Gain Rate" and "Zone Ideal Loads Outdoor Air Sensible Heating Rate" in Output:Variable, it was confirmed that there was a significant difference between the two.

I checked the "SizingSummary" and found that the "Design calculated Load" and "Zone Ideal Loads Outdoor Air Sensible Heating Rate" had similar load values.

Where does the "Zone Windows Total Heat Gain Rate" number disappear to?

This may be a silly question, but please tell me!

Thank you!

@KAZ what simulation tool are you using? It sounds like EnergyPlus based on some of the outputs, but I just wanted to check. You should add a tag for that software so that others can provide better help.

Hello. As you said, this is a simulation with "Energy Plus".

I don't know anything about it and would love to know! I don't understand why the "Suraface Heat Gain Rate" per Timestep is not the load for that time.

There seems to be a big difference there in my calculations.
