Different rules apply to interior glazing than exterior glazing. I think there is also a figure to illustrate it. The figure you show is surely for the exterior glazing. PS. If you figure out how to setup a weather file or ddy to reflect CIE clear sky, please let me know. I've been aching to test e+ daylighting against radiance which we can do both in designbuilder using the same model.

Dear Jean,
Thanks a lot for your advice. You are right, Radiance is more powerful for daylighting simulation.
Referring to figure 10 in the Input-Output Reference Manual of EnergyPlus, transparent glass should allow beam reflection. Referring to the attached "Input-Output reference Figure 10.PNG" file, I added some texts and a facade sketch in green.
If EnergyPlus can allow beam reflection using transparent glass, I would like to study daylighting (CIE clear sky) and energy utilization in an atrium model at the same time.
At present, I could only have diffuse reflection in my model. I could not understand how to achieve beam reflecton in my model.
Can anyone please kindly help me?
Best regards,
Stanley
