What is the best way to find the type of sky (whether it is overcast, sunny clear, clear, uniform cloudy) in EnergyPlus. I read in the InputOutput Reference that sky clearness (obtained from Output:Variable,*,Site Daylighting Model Sky Clearness,hourly;) close to 1.0 corresponds to an overcast sky and Sky Clearness > 6 is a clear day.

Do we have reference values for all sky types? and What if the hourly output of Sky clearness does not exceed 6 through out the year, does that mean that there was not a single Clear day?

I wanted to run my daylighting simulation on different sky conditions to find illumimance distribution in my model
