RE: [EnergyPlus_Support] Re: system sizing data transfer





I vaguely remember that Daylighting controls are turned off during sizing.  ie are not available.

Oh sorry,  you are right, that object doesn?t have a schedule.  I?ll try to add that as a suggestion for a future version. 
 
I can think of various work-arounds using EMS (but they may be more advanced than copying over the sizes).  For example you could actuate OtherEquipment to make up the missing load from the dimmed lights.  Or you could intervene directly with the sizing results using the system sizing actuators.

Ok, this is smart, maybe it is the solution to my problem.

But still I can't make it work for Daylighting:Controls. This object does not seem to be controlled by a schedule.
