I want to use the illuminance data from my real weather data file to do the daylight calculation in EnergyPlus. So far as I know, EnergyPlus does not use illuminance data from weather file directly. All the illuminance values used in simulation process are derived from radiation data.

What should I do to make illuminace data in .epw file being used directly in daylight calculation? Can this be done by recoding some lines in Weathermanager module and/or daylighting modules?
