Kukui Cup 2012 Energy Data

  1. 1. 2012 UH and HPU Kukui Cup Energy Consumption Data: Preliminary Report Philip Johnson Collaborative Software Development Laboratory Information and Computer Sciences University of Hawaii(1)
  2. 2. UH Data Background Data points at weekly intervals. Prior to challenge (August): • One data point last week of August Challenge (Month of September): • Four data points during September. • Orange rectangle highlights interval Post challenge (October) : • Three data points in October.(2)
  3. 3. UH Building-level Data(3)
  4. 4. Lokelani and Mokihana Buildings(4) Upward trend in consumption.
  5. 5. Ilima and Lehua BuildingsLehua "flat" for first 2 weeks, then upward trend(5)
  6. 6. UH Lounge-level Data For ease of review, only 2 or 3 lounges per chart(6)
  7. 7. UH Ilima A, B(7) Little apparent impact of challenge.
  8. 8. UH Ilima C, D, E Ilima-E: flattened for first week, then upward. Ilima-D: flat the whole way through.(8)
  9. 9. UH Lehua A, B Little apparent impact of challenge.(9)
  10. 10. UH Lehua C, D, ELehua-D: ~9% decrease from 8/27 to 9/17 (64% participation)(10)
  11. 11. UH Lokelani A, BLittle apparent impact of challenge. (43%, 9% participation)(11)
  12. 12. UH Lokelani C, D, ELittle apparent impact of challenge. (50%, 20%, 33% participation)(12)
  13. 13. UH Mokihana A, BLittle apparent impact of challenge. (28%, 38% participation)(13)
  14. 14. UH Mokihana C, D, ELittle apparent impact of challenge (38%, 32%, 21% participation)(14)
  15. 15. HPU Data Background No lounges: all building level. 3 week challenge: • September 17 – October 7 • Orange rectangle around interval Lehua building data • Not available due to meter misconfiguration.(15)
  16. 16. HPU Lokelani 20% drop from 9/17 to 9/24 (100% participation)(16)
  17. 17. HPU Mokihana 13% drop from 9/10 to 9/24 (64% participation)(17)
  18. 18. HPU Melia Little apparent impact of challenge. (8% participation)(18)
  19. 19. HPU Kukui Little apparent impact of challenge. (9% participation)(19)
  20. 20. HPU Ilima Little apparent impact of challenge. (9% participation)(20)
  21. 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. 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.(22)
  23. 23. HPU building consumption flat(23)
  24. 24. UH building consumption increased 13%, 19%, 26%, 26%(24)
  25. 25. Questions?(25)
