[Equest-users] Sizing runs in baseline model

How about the SS-H report?  That will show the fan energy, as well as DX
cooling and furnace heating for specific AHU(s).



Task lighting is already broken out separately in the standard end-use
report, although if other zones had task lighting then it would be comingled
with this process task lighting and not necessarily all process.

Thanks, David. I could have been more clear. The sub-meter first came up
when we discussed our big exhaust hood / makeup air unit. They wanted to see
that energy shown as process energy. Later in the discussion, and this is
where my notes got fuzzy – task lighting and receptacle loads got mentioned
as process energy – I don’t know if they asked that those be put on the
sub-meter too or not.



Here’s what I’m looking at















Meter EM1-A is my sub-meter. All three dialogs are in the same zone. If I
switch “Task Lighting” and “Elec Equipment” to EM1-A, will eQUEST
automatically assign the numbers circled above to this meter? I can’t see a
way to assign loads to a meter within the zone internal loads dialogs…

I think it shows up pretty clearly as “miscellaneous equipment” end-use in
the eQuest reports, so I’m not sure why they asked you about the submeter,
unless there was some inquiry about splitting up components of the process
load…I think it is an unneeded step, but you’ll have to work that out with
the reviewer as to why they asked specifically for it.

Hi!



I got the unmet hours fixed in my baseline model. I think it had something
to do with the return air path – I had switched them from ducted to plenum
(to match design case because I didn’t see an App. G requirement for it) but
had them as unconditioned.



Back to the sub-metering question. I missed this in my discussion with the
review team –would it make sense to put ALL the process power on the
sub-meter as a way to directly see it? Seems that way to me. For our project
process power includes:



·         Receptacles (office equipment and task lights)

·         Refrigeration

·         Cooking



I don’t think there are any difficulties in assigning these to the
sub-meter. I see there are places to directly assign them in the meter
properties – is there a risk of duplicating / double-counting them if
they’re also entered at the zone / system inputs?



Thanks, all. Have a great Memorial Day weekend and take a moment to thank a
Vet!
