CUSUM Analysis
The CUSUM chart displays the CUmulative SUm of the deviation between actual and
target dependent variable in successive intervals. The CUSUM chart has a number of
properties that provide tools in analyzing your energy usage.
 When the trend is horizontal or nearly so, it signifies that deviances are equally
balanced around zero, that is, that the monitored process is operating near the current
target.
 An upward trend signifies persistent over-consumption relative to the current target,
while a downward trend indicates cumulative savings.
 Points of inflection (where the slope changes markedly) signifies a change in the
behavior of the monitored process and can point to opportunities for improvement.
