#2658 CBECC-Com Issue - Unmet Load Hours Issue

[Felicia Lee]

Version = 2016.3.0_963

Category = HVAC

I was wondering why these zones are showing so many unmet heating load hours even when they have baseboards. Please direct me to the points I should be checking to fix this.

I see a couple problems with your model:

1. The auto hardsizing for the main “VAV” system is 0.330 cfm/ft2, but several of the zones require more airflow (> 1 cfm/ft2). This will cause UMLH.
2. The VAV (DOAS?) heating coil heat pump has a supplemental heating coil which is referring to itself. This will cause an issue.
3. Please see the attached log file generated from the run, which shows several warnings. These can indicate the possible causes for the issues.

Will close if no response received from user.
