To the original post: it's likely either a problem with the system or more likely a building manager that doesn't know how or care to set the system properly.

I'm of the opinion based on what I see in our building, (and I have full trend data capability on a 480 ton system) that if there's nobody in the building there's no need to run A/C. Just make sure it's started early enough to be cool by the time people arrive.

For our building that's 4:30am in fall to spring and 3am in the summer.
