[Equest-users] unmet heating load hours

Four hours doesn't seem unreasonable...you are referring to a requirement to not have more unmet hours in the proposed than the baseline?

My suggestion is to take a look and see when these hours are occurring to try and find a common theme -  what's the occupancy then, time of day where the spurious hours could be at start-up or later in the main shift, or during a lightly occupied time?

This might lead you to identify an equipment capacity constraint or else a tweak to the control scheme in use for the zone(s).

Subject: [Equest-users] unmet heating load hours

I have a Costco warehouse equest model with 4 unmet heating load hours in my proposed model with zero in my baseline budget model.  I need to be able to tweak my model to get rid of these unmet load hours but minor tweaks don't seem to make a difference.  Could there be something wrong with the model that results in having a few unmet load hours that are hard to get rid of?
