[Equest-users] Electric Peak Demand

Amy:  Sounds like a simple mix-up.

The BEPU report displays annual consumption totals for each meter.  The
PS-F reports by contrast include both consumption sums and demand values
corresponding to the hour of maximum draw for each end-use (scroll to the
bottom for annual peaks and consumption totals).

You might find it easier for documenting your first few LEED models to
reference the graphical end-use reports for consumption and demand – that’s
how I started out:

I used the values found in the BEPU report to put in the online template.

This doesn’t sound like an issue with your electric rates. They are saying
that the actual peak demand that you reported in the LEED template does not
match the peak demand by end use stated in the PS-F report. What was the
source of the values you inputted in Table EAp2-5?

I received the following comment back from USGBC and was hoping someone
could help shed some light on this for me.

*Table EAp2-5 indicates peak demands have been reported for the Baseline
and Proposed cases; however, these values do not coincide with the energy
modeling outputs provided.  For example, Table EAp2-5 indicates the
Proposed Case lighting peak is 879.8 MBH (257.8 kWh); however, the PS-F
report indicates the peak Proposed Case lighting power is 34.022 KW.
Review the energy modeling output reports and remove any demand value

The project was designed around a uniform electric rate of $0.0703/kWh and
this amount was entered in the Electric Utility Charge screen 4 of 7 in the
wizard mode (photo attached).

Is the USGBC comment aimed at the utility rate or is it something that
needs addressed back in Wizard mode?  If so, how do I go about fixing it?

Any help / guidance is much appreciated.
