Unmet hours Sim File Discrepancy

7 posts / 0 new
Last post

Greetings, I have 1320 hrs above cooling throttling range as seen in the BEPS report of the sim file.

However, I am attempting to identify which zone is causing the unmet hours and have been unable to locate the problem zone.

The SS-F report only shows a few zones with a couple few hours unmet, nothing adding up to 1320. And the Air-side Summary Report is showing 0% hrs ouside thrl-range.
I thought there was one something that showed the real unmet hours total in the Space Loads Report somewhere but I am unable to find it.

Thanks for the help.

Thanks Brian, SS-R shows a whopping total of 25 unmet hours for all systems.

Hi Kevin,
What I like to do is look at the summary tab for each system. If you go to "air-side hvac" and highlight a system in the component tree the select the "summary" tab you will be able to see the space and system total unmet hours for both heating and cooling. By going through each system in the component tree you should be able to identify the problem spaces/system.

Thanks,

Thanks Matthew, the Air-side Summary Report is showing 0% hrs ouside thrl-range and also has the whopping total of 25 unmet hours as seen in the SS-R report.
Still trying to identify why the BEPS states 1320 unmet hours.

Maybe if I uninstall the program and reinstall it might work.

Kevin,
It has something to do with your Cooling Design Day. When I change NUMBER-OF-DAYS from 120 to the default (1), the unmet cooling hours goes to down to 11. Cue the Spinal Tap jokes?
