Hi, I have modeled a simple building with a window and fixed shading (without any control). I have added details regarding the illuminance reference points and maximum illuminance levels in "Daylighting:Controls".I have added "Daylighting Reference Point 1 Glare Index " as an output variable. But when I am running the program, it is giving a value of zero, whether run hourly or monthly or annually. Please let me know if anything else needs to be defined for obtaining the correct result.
