Another alternative is SurfaceProperty:SolarIncidentInside which allows the incident solar on each surface to be specified with schedules. This would require getting the hourly or timestep values for incident solar flux on each surface from Radiance or another tool capable of doing the full interior solar distribution calculations. Note that this is the final answer for solar incident on the surface after all internal reflected solar. The schedule value is multiplied by the surface solar absorptance to set the absorbed solar for the inside surface heat balance. No further solar distribution is done for surface that have one of these.
