[Equest-users] Unmet Hours

[David Griffin]

Gerry,

The summary report in eQUEST illustrate noncoincidental unmet load hours while the BEPS shows coincidental unmet load hours. I did not open your file, but I'm guessing you have core and perimeter zones with unmet load hours at different times due to their load profiles. When I have that many unmet cooling load hours on my BEPS reports I usually do one of the following:

1)    Look for a rogue zone causing issue

2)    Look at the 'big' picture (i.e. did I specify a schedule or have another input that conflicts in the model and is preventing proper cooling).

3)    After exhausting all other resources, I start manually increasing my airflows in individual zones to decrease the unmet load hours.

I hope this helps.

Thanks,

Subject: [Equest-users] Unmet Hours

Hi All,
I have used the summary report to identify systems/zones with unmet cooling hours and addressed them to the point that the  report now shows no one zone with more than 233. However, when I check the BEPS it shows 2174. I have not come across this before. I am hoping  someone can shed some light on my next move.
Thanks,
Gerry Hazel
