[Equest-users] Problem with Submetering

[Chris Baker]

So I was going through my leed online submission this evening and noticed that in the "PS-E" reports equest combined my plug loads with my cooking equipment and comm room power.

I attempted to apply 2 new submeters for these but after finishing those equest gives me an error running the simulation - 2 "standard file writing errors".  Thus, the simulation wouldn't run.

I then experimented with deleting cooking equipment and comm room equipment from the miscellaneous utility loads (so that plug loads show up only).  I then created two new "utility" meters - one for cooking, one for comm room power.

This appeared to operate perfectly fine and without errors.

This did separate the power just fine but is this a standard procedure for LEED review?  And if doing this, what else should I look out for?

>From what I'm seeing in equest there isn't any way to link a "submeter" to an existing utility meter.  Instead, they are treated as independent entities with their own assigned loads/schedules.

However, it would appear new utility meters can be linked to a parent "utility meter".

However, if I'm modeling power flowing to these two processes independently of the primary electric meter, I would assume I would NOT want these linked to the parent meter.
Just because that would double-counting the power usage in the proposed model (=BAD?)?

I searched in the forums for a while reading up on submeters but can't find a solution to this issue, specifically.  I know there's a simple fix I'm just kind of a newb.

>From what I've read, however, if you apply a submeter you typically would want to keep your miscellaneous loads unchanged at the zonal level.  I'm assuming a submeter would simply monitor the power usage while the process still gets power provided, and monitored by, the primary electric meter.
