21. 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/Lokelani: 100% participation, 20% drop
• HPU/Mokihana: 64% participation, 13% drop
(21)
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.
