About unmet hours

Dear all,

I'm trying to reduce the unmet hours in my model. The strange thing is that all zones are carefully controlled, meeting temperature requirement (checked in SS-R and SS-F report). Most of their unmet hours are zero, and few of them have some dozen of unmet hours but no more than 80.

However, the overall unmet hours of my model is still above 1500 (Checked in report BEPS).

Has anyone been faced with the same problem? Is there any solution?

Thank you!

Sherry

Sherry,

It's possible that your unmet hours in various zones are all at different
times. As noted in related threads on this topic, if every single zone in
your model has 100 hours of loads not met, but those loan not met instances
all occur during the same hours, then the overall loads not met in the BEPS
report is 100 hours, whereas if you have a hundred zones each with 1 hour of
loads not met but the hours are all at different times, then you will still
have 100 hours overall.

You likely have some schedule or loads diversity in your model that is
causing loads not met in different zones at different times of the day.
This is a common problem, and several people have posted about it. Search
