[Equest-users] Demand Direct Process Load

Fri Oct 2 13:42:44 PDT 2015

Hello Brian, that right there is a shift in the moment of the peak demand.
Does anyone know how to resolve this in the model or in any case how to deal with it in the LEED submittal for the reviewrs no to coment on it?

I have done lots o models and never came acorss with this issiue previsuly.

Best regards.

I would look at your PS-E report to see when the peak loads are occurring in your proposed and baseline models.  I suspect that the slight shift in when the peak demand is being set changes the breakdown of that peak demand.

Hello David, thanks for the tip on the process loads.

In the following table the results show that the KWh for the receptacle equipment is the same but we get -15.4029 in demand saving. (We triple check schedules and w/sf they are exactly the same)
Additionally we use the "Exterior Usage" and "Task Lighting"  categories in the Electric Meter Direct loads ( for water pump, elevator, exterior lighting), using the same Schedule and Load (KW). As you can see the show saving in Demand.

What would we change In the *.SIM file to get the same results in the process load?

Thanks again for your help!

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.

Hi,
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.

Thanks,
