[Equest-users] Need help- Model not calibrating- Usage way above monthly history from bills

[nirupama lakshminarasimhan]

I have modeled a high school building (NH) on eQuest. It is participating
in a state funded incentive program. I’ve been using the software for 2
years now, but cannot figure out why the electricity and fuel usage from
the model are at least 40% above actual usage.



Mysteriously, I have significant electricity use from space heating, when I
have no electric heat in the facility- does this number refer to auxiliary
components in the heating systems? Because the corresponding fuel bills are
also high.



I have condensing propane boilers with distribution through terminal units
including unit heaters, cabinet heaters, unit ventilators, baseboards and
roof-top air handlers.



The “vent. Fans” and the “pumps & aux” categories also read high apart from
the “miscellaneous equipment”- I could fix the miscellaneous loads. But as
far as the other categories go, I do not know where to even begin
troubleshooting.


This was the first model that I used the detailed interface from start and
built it way back in November 2012. And since I am at a loss of technical
language to describe this, I need help with reducing the electricity and
fuel use in the building- especially with editing information related to
schedules, meter assignments and/ or temperature set points to avoid the
heating and cooling units working at the same time.
