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

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.

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
