But as far as unmet hours in the proposed case, I would suggest looking at the airside summary in eQUEST. Such huge amount of unmet hours 68.9% usually means that the problem could be coming from<br>1. one or 2 systems which have a huge number of unmet hours <br>2 and that its something basic like heating/cooling system inputs or capacity/loads mismatch or your setpoints<br><br>I would suggest looking at how that 68.9% percent has been arrived. is it even distributed unmet hours across all systems in the building, if it is then there is a mismatch between your loads and design or if its just one system then check your inputs for the system and how the system size compares to what equest auto sizes it to etc, then check the loads. I am sorry I am being very vague here.<br><br>This is where I would look first to solve unmet hours problem. And from your write up it appears that once you solve this the next step might be easier. Again I could be totally incorrect ...so I will wait for you to provide an update when you crack this.
