Natural and artificial lighting [lux]

Hi!

I'm working on an outdoor lighting project. Previously, I've worked on other projects calibrating energy models using EnergyPlus and jEPlus, and I'm currently trying to find a way to obtain a dynamic and relatively calibrated model to predict how much artificial lighting I need to use, in addition to natural lighting, to meet the conditions of my outdoor area.

Through my experimentation, I've found that by using the Daylighting: Controls and Daylighting: ReferencePoint objects in EnergyPlus, I can determine how much to reduce the power of the artificial lighting based on the natural lighting that reaches the sensor in order to meet the conditions I've specified. However, I cannot obtain the lux produced by the artificial lighting as a result.

I've also tried other simulation programs such as Dialux, but in this case, I only get the information I need during the day since it does not combine natural and artificial lighting for outdoor areas at night.

Do you have any ideas on how to calculate the lux produced by artificial lighting at night in EnergyPlus?

Thank you for your attention. Regards.
