I would like to know the contribution of the interior windows to the zone energy balance. I have tried with the following report variables:

Zone Interior Windows Total Transmitted Beam Solar Radiation Rate. Reports 0 values. I thought that solar radiation was always diffuse after an interior window, so, why does this variable exist?
Zone Interior Windows Total Transmitted Diffuse Solar Radiation Rate This variables is reporting values
Surface Window Transmitted Beam Solar Radiation Rate.This variable, for the interior windows, is in the results sql file but with zero values.
Surface Window Transmitted Diffuse Solar Radiation Rate. This variable, for the interior windows, is not included in the results sql file.
Surface Window Net Heat Transfer Rate, Surface Window Heat Gain Rate, Surface Window Heat Gain Loss are not include in the results sql file for the interior window.

What am I missing? How can I study the contribution of the interior windows to the zone energy balance.

Thanks in advance.

If I´m not mistaken, the first variable would depend on your Solar Distribution model. You´ll need one of the options using Interior and Exterior calculations and your zones not to be convex (More on the E+ Input/Output manual).

Additionally, any beam solar that reaches your interior windows through the outer zone is transferred as diffuse to the inner zone (still, I think that the first variable should report values as long as you have the right solar model and concave zones).

Thanks Rafael. I am using very simple convex zones and the FullInteriorAndExteriorWithReflections model, but the variable "Zone Interior Windows Total Transmitted Beam Solar Radiation Rate" reports 0 values.
