[EnergyPlus_Support] Illuminance measurement

[Fábyo Luiz Pereira <fluizp@xxxxxxxxx>]

   Dear all,

   How is determined the "Ltg Power Multiplier from Daylighting" if the
daylight sensors only measures daylight illuminance? I mean, where is measured
the artificial illuminance from lights? This is measured (calculated by E+) but
can't be reported?

   For example, if I want 500 lux in one environment and the sensor is
measuring 400 lux, lights will contribute with 100 lux. This artificial
illuminance to reach the 500 lux is given by E+ as lights electric consumption.
So, if the electric consumption fluctuates all day long, and in fact this
happens, means that daylight illuminance is fluctuating.

   Thanks!
