Subject: [Equest-users] Reconciling Building Energy Performance with Space Load Components


Hello,
I am relatively new to eQuest, and trying to analyze the output from one of my models.  I am having trouble reconciling two of the reports: BEPS (Building Energy Performance) with LS-E (Space Monthly Load Components).
My model only has 3 spaces, and the totalannualheating load for the three spaces is: 62.240 + 34.887+ 66.305 = 163.432 MBTU.
However, the BEPS report shows a total heating fuel use for Natural Gas of 113.0 MBTU.
The fuel number should actually belargerthan the sum of the heating load, since there is some loss of energy in the conversion of the fuel to heat.  In this case, there isactuallya smaller amount of BTUs in the fuel for the overall building.
If someone understands how this works, please let me know.
Thanks,
Michael R. Young, P.E.
