feedback, but before the display was taken away, we can conclude that electricity waste feedback
to both operators and managers makes a significant difference. The observed average reduction in
waste from control during the third phase of the field experiment was 43%, corresponding to an
absolute reduction in energy usage of 26% on measured equipment.
The argument can be made from both a statistical and analytical sense. On a statistical level, the
p-value of the test (0.01) indicates that we can reject the null hypothesis with confidence. Moreover, it was observed that soon after being trained on using the dashboard, senior management introduced
a simple paper audit checklist (Figure 5-12) that was taped prominently to one of the ovens in the
middle of the room. The checklist included the elements of each oven that should be shut down at
