One of my tasks is to study the effect of daylighting on lighting energy performance, and I set the parameter according to the examples in E+. But I can't find the maeningful result from the output.Maybe there are some errors in my setup, but I'm not sure about it. So, I ask this question here.(Ps. the targrt zone is ad5

I assume you have to compare two models (with and without atrium?). You can add daylight reference points (maximum two) to study daylight savings. In Daylighting:Controls object, you have to input required lux level and lighting control type. By doing this, you will be able to compare lighitng energy consumption for both models.

Please see THIS, explaning how to add dayligting control objects by using OpenStudio.
