Thanks! Thinking about it the way you said makes complete sense, and when I ran it again after lowering the minimum sign

I've been working on a fairly simple model in OpenStudio, and for some reason, when I allow the VAV boxes to control for outdoor air, the electricity used by cooling increased very significantly in the colder months (January, February, November, December in particular). I can't seem to figure out why this is happening?

I have a fixed drybulb economizer in my AHU's that is set to a maximum limit temperature of 72F and a minimum limit temperature of 55F. I don't know if those values are affecting this either.

I can supply more information if need be, I just don't know what all could be affecting this.

Thanks for the detailed response! Editing the Setpoint Manager in the plant loop did exactly what I was wanting!

I'm definitely a novice with OpenStudio in general, but I'm trying to get my chilled water loop to be able to turn off in the winter. (Currently the cooling coils are on the Always On: Discrete availability schedule)

What I can't figure out is how to create either a schedule or availability manager that will help me accomplish this. Any help is much appreciated!
