Insight 1: Participation Level of participation is correlated with perceptible change in consumption on weekly basis.

If participation is greater than 60%, then consumption changes perceptibly•UH/Lehua-D: 64% participation, 9% drop•HPU/Mokihana: 64% participation, 13% drop•HPU/Lokelani: 100% participation, 20% drop

(22)

Insight 2: Building level trends UH buildings showed a significant increase in energy consumption from August to October. •Effect of competition was to temporarily "flatten" this increase.

HPU Buildings did not show this trend.•Effect of competition was more significant.

Not sure why there is this difference between UH and HPU.

(23)

HPU building consumption flat

(24)

UH building consumption increased 13%, 19%, 26%, 26%
