Demand Direct Process Load

I'm modeling a building for LEED, but when I go to equest LEED report I notice that my direct process load for demand is not equal, anyone know why this happen?

I review the rate and the schedules and are the same also the energy load is the same for the proposed and the baseline.

Is the process load on a hot water or chilled water loop? I think these are
dependent a little on the overall loop temp/load and are never same for
different runs. If it just an internal load, then look at the schedule also
to make sure that is same.

Double check the timing of the peaks - the graphical presentation in eQUEST is the coincident peak - the contribution of each component at the time that the building hits its total highest demand.

It's likely that the proposed building has a peak later in the day due to one or more efficiency measures that are included. If the process loads are lower at this time, the graphical presentation will show that the peak component is less than the baseline case. (Or if the process ramps up later in the day, it could be more?)

You'll need to go into the *.SIM file to get the reported peaks for the process loads (and show the annual totals to also be the same) to demonstrate that the schedules are consistent, or otherwise explain to the reviewer what is happening.
