On one project the reviewer demanded that I
increase the plug load cost from 23.5% to
25%. In my experience, the reviewer always looks
for this one as it is an easy one to point to so
the reviewer looks like he/she is doing their job.
I use Table E2 from CBECS
(http://www.eia.doe.gov/emeu/cbecs/cbecs2003/detailed_tables_2003/2003set19/
2003pdf/alltables.pdf) to verify that the fraction of process/plug loads is
in right ballpark for various building types.
Unfortunately the reviewer was incorrect in their interpretation for that
review. GBCI is working hard to ensure a higher level of consistency in
LEED reviews. The change from the Certification Bodies method to bringing
reviews in-house at GBCI should go a long way to achieving better
consistency.
Also while it does appear that the 25% is being calculated based on energy
use, we have been assured by the author of the form that it is indeed being
calculated based on cost.
