I've noticed some OS reporting behavior, for occupied unmet hours, that I suspect is incorrect. Was hoping to get some feedback to see if others have noticed this behavior or perhaps there is something I'm missing.

After running the first OS simulation, I checked on the number of unmet hours:

Not too bad on the occupied side, but always good to check any # of occupied unmet hours, so I wanted to see which zones were involved. Time to check the "Zone Conditions" section of the standard OS report:

However, it appears that the number of OS-reported unoccupied unmet hours is the same as the number of occupied unmet hours! The same issue is observed for both heating and cooling unmet hours.

Digging further into the E+ SQL output file, I observed that the # of occupied unmet hours does not equal the value reported in the OS report. As an example, below is a plot for Thermal Zone 1 - Conference:

As you can see, the number of occupied unmet cooling hours is 0 for the year. The OS report shows there are 658 unmet cooling hours. Thus my confusion...
