Energy
Expert incorporates a modeling
algorithm developed in cooperation with
the U.S. Department of Energy that uses
energy interval data and weather data to
generate reliable feedback about how a building
is performing in terms of energy use.
More specifically, the methodology
used in Energy Expert is bin-based, where
the bin is a set of values of a dependent
variable (energy interval data) with which
the value of another independent variable
(outdoor air temperature) is associated.
To explain variations in energy use,
two or more descriptive variables such as
day of the week, hour of the day and outdoor
air temperature are used.
The model is “trained” by collecting
data and assigning it to bins.
The median of the values of the dependent
variable (energy interval data) in the bin
serves as a good representative value for
both large and small numbers of samples
per bin. This median value is the “Expected”
or “modeled” energy value.

Executive Statement
Energy Expert+Plus is used to understand
the performance of the whole building
and to determine whether there are
indications of problems in the way the
building or its systems are operating.
Short and long term monitoring data on
whole building heating, cooling, or
electricity consumption, return air
temperature, etc. may be examined in an
attempt to identify failures in the
equipment or the systems in the
building, or the data may be examined
for signs of sub-optimal operation. This
approach can be expected to spot large
problems, e.g. problems which typically
lead to increases of 5% or more in
energy use.
Whole building data for heating,
cooling, and non-weather-dependent
electricity consumption can be used to
identify a range of shut-off
opportunities, scheduling changes, and
operating anomalies due to improper
control settings and other factors.. It
is then very straightforward to reliably
predict the energy savings which will be
realized from correction of these
problems.
It should be recognized that the systems diagnostics available from whole
building data and modeling are
indications of probable cause.
Additional field measurements are
generally needed to confirm the probable
cause. |
