I know I've been hounding everyone with questions this week, but I think I'm getting really close to figuring this out. I have implemented a bunch of schedules for OA, economizing, etc. I think they might be conflicting with eachother somehow, because when I produce an hourly report it says heating and cooling are on 24/7, even when the fan isnt on. Also in the report I noticed at random times that there is no load to the coil at all during occupied hours, so the fan shuts off but the heating and cooling stay on. Anyone ever had this problem? I have attached pd2 and inp files. Thanks for the help!

Hi All,
I have received the following request for information from an energy model:
Please attach a plant entered values report to verify that modeling conforms
to Appendix G.
Any idea what a "plant entered values report" is? I am assuming it is a
series of screen shots showing inputs or maybe a PV-A report but want to be
sure. I must be missing the obvious (again).
Thanks!

Jeff,
I would say one or the others: both the PV-A or the screen shots might be able to do the job.

That's actually a Trane Trace specific term, so your reviewer may be
thinking you used a different software than you did. If you didn't use
Trace, I would suggest directly contacting your review team to ask them
to clarify for the software that you did use. I'm assuming that is
eQuest based on your post being in this forum :)

Hey Jeff!
It's not unusual to find reviewers requesting/demanding items in terms
vague enough to suggest they've either never handled an eQuest model, or
else don't care enough about their work to be specific. I try to accept
these realities, and prefer to assume they're compensated appropriately
for their qualifications and effort.
Since your reviewer is putting forth minimal effort to describe what
he/she wants to check/assess, I would just supply a PV-A report as
that's the corresponding minimal degree of effort on the modeler's part.
If you've got time to burn or really want to nail the coffin, I suppose
it wouldn't hurt to make a 50-page animated powerpoint on all the plant
inputs with illustrations and an accompanying soundtrack... but as you
can see this makes for a disconnect in the rigor of the review when you
don't follow your reviewer's lead.
Hmm - soundtrack suggestions for a boiler/chiller plant anyone?

PS: I don't want to sound negative/pessimistic - I have had the
pleasure of working with reviewers who are outstanding at their jobs.
Great reviewers are both specific and direct in their commentary, making
it easy to respond, make corrections as required and even (gasp!) learn
something. Good reviewers will put forth a level of effort that can
both educate and inspire us to model to a higher standard - I hope they
know their work is appreciated!
PPS: Jeremy's response came out just as I was finishing this - opening a
line of communication with the reviewer is a fine idea, if that is
indeed an option. If I'm not mistaken, USGBC/GBCI has always done a
pretty good job of making reviews a nameless/faceless experience
however...

LEED-Online v3 has a new line of communication open: if you go into your
project and look at the team administration tab, it will say at the top
"Your project has been assigned to" and will have a team name as a
hyperlink. If you click on the hyperlink, it opens up a contact
information section that gives you an email address.
I'm not certain if all team members can see this - I can but I'm quite
often either a Project Administrator or a Project Team Manager. If you
can't see it or don't have access to LEED-Online for the project - talk
to your Project Administrator and they can send the email. No
guarantees you'll get a prompt reply or a reply, but many of the teams I
have contacted this way have responded within a reasonable time frame.
They'll tell you if they can give you the answer you are asking for or
if you need to file a CIR or a ticket with customer service.

Well it doesn't seem too hard to figure out if you look at the 2 clues: *plant
entered values* and *Appendix G*. If we figure that they are reviewing an
eQUEST submission, which seems obvious, we know that the eQUEST Plant
includes chillers, boilers, pumps, etc. Then we can look in Appendix G and
see what the requirements are for those pieces of equipment.
I personally use PV-C the most. It has lots of good information like sizes
of boilers, chillers, pump heads, gpm, etc. Check it out.
Best,
Carol
