[Bldg-sim] eQuest Energy Simulation program

[Vikram Sami]

Eric,

Thanks for the tip about the program - that's pretty cool. 

 

Andrew - another area that might be contributing to the discrepancy is
scheduling. Make sure you are using identical usage schedules for both
buildings.

There is a great free program called Exam Diff that we use to track down
differences in input files:  http://www.prestosoft.com/edp_examdiff.asp 

 

If you are only looking at operating costs, another possibility is that
your are using utility billing rate information that allows demand
charges to be calculated.  If you use this method rather than a straight
$/kWh approach, you will have subtle differences in operating costs for
different end uses.

Hello. I am using the eQuest program and have a problem I'm hoping
someone can help me with.

 

I have reviewed all of the input affecting 'Misc. Equip' energy usage
(per the 'Description of eQuest/DOE-2.2 End Use Reporting Categories')
and have verfied all the inputs for both my Baseline and Proposed
buildings are identical, and that no parametric run parameters modify
those inputs, and yet my outputs remain substantially different.

 

As the LEED reviewers are insisting that my 'process' loads be identical
for both the baseline and proposed buildings, I need to either find a
way to correct the apparent mistake, or find a way to move the portion
of the Misc. Equip output that is changing to a non-process energy
meter. (I have been unable to locate where these particular inputs are
assigned to one meter or another).
