10.0pt;font-family:Arial;color:navy'>To me, “calibration” would
require loggers on the lighting, major HVAC components and electrical panels to
record such things as operating schedules, temperatures and peak kW demand, and
matching the model results to the annual utility data, usually within 5% for
annual electrical consumption, gas use and electrical demand. The model
will likely require several iterations to develop the calibrated baseline, but
then you have the increased confidence level in predicting “X% less
energy use” when you change “Y” in the baseline.<o:p></o:p></span></font></p>

have used equest a number of times to show clients the relative effects of

heard the term “calibration” as it relates to models, and I think I
understand the concept, but how is this actually done? Is it just a
