Hi, everyone

I am investigating the energy saving of prismatic daylight redirecting fenestration (PDRF), whose fundamental is that the light is introduced into the deeper inside by PDRF, thus the daylight would be fully utilized, resulting in less artificial lighting energy and lighting heat gain. However, the daylight model in Eneryplus cannot model the redirecting effect of PDRF, so I would like to use EnergyPlus to couple with radiance. The illuminance calculated by Radiance where the sensor is placed is transferred to EnergyPlus in each timestep. I know BCVTB can implement a couple of Energyplus and Radiance, but I don't know which variable in Energyplus should receive the calculated illuminance of Radiance.

Any Suggestion?

Thank you!
