Hi! Happy New Year to you too :)
My thesis uses heat balance in EnergyPlus as a base for understanding the thermal performance of buildings. Then, If you want the convection heat balance related to zone air (I assume this based on your question), I think this article could provide the answer that you need: https://www.researchgate.net/publication/369186777_Convective_heat_balance_applied_to_thermal_performance_analysis_of_buildings
In brief, for any surface, the output for convective heat exchange is Surface Inside Face Convection Heat Gain Rate [W] or Energy [J].
There are many outputs for windows, and the "right one" will depend on your analysis. However, the Surface Inside Face Convection Heat Gain is sufficient for convective heat balance. And if you have a frame/divider on your window, you also need to consider the output Surface Window Inside Face Frame and Divider Zone Heat Gain Rate [W] in your zone air heat balance.
