[EnergyPlus_Support] Detailed Gaylight Calculations

[ogocer@xxxxxxxxxxxxxx]

Dear All,
Daylight illumination level at reference point seems very high. Although i
set 500 lux, in output reports it reaches 1500 lux. i specify light
control type as 3 and i can understand when it reaches 1500 lux even if
lights are off, i need blind control. But at early hours e.g at 8 o'clock
daylight illuminance level is under 500 lux. i think it must be 500 lux as
specified before. i can't understand the reason of it!
And second question  how can i define the design level of lights in
internal space gains objects? (assuming there is no daylight and
illuminance level is achieved by artificial lighting), does excessive
design level assumption affect daylight illuminance level?

thanks
