[Equest-users] Unexpected energy consumption related to occupancy increase

[Morteza Kasmai]

Joe / David,



Many thanks for your suggestions, but I had no luck to find out what
differences resulted this issue; finally I switched back to wizard mode and
fixed the number of occupancy in the proposed model. Now both models have
the same occupancy and there in no significant increase in the energy
consumption. From this experience, I learned that is safer to fix the
occupancy within the wizard mode; as Joe pointed out, occupancy affects
many other operations that might be not easy to fix it in DDE mode.



Regards,
Morteza

Can you use a file comparison tool to compare the two *.inp files and see
what differences resulted, beyond those that were intended?

I like Compare-It! for this purpose, and there are others.

total building occupancy from eQuest default numbers (321) to real numbers
that I have for the actual design (361), total building energy consumption
increases tremendously (from $135,741 to $144,114). However, when I
increase the occupancy in the baseline model (with System 6), the total
building energy consumption does not increase too much. Please refer to the
attached files (INP and PD2 files of proposed model with different building
occupancy).
