Thank you for everyone's effort and enthusiasm in helping reduce energy usage in our Residence and British Columbia as a whole. Together we're creating energy awareness for everyone and for our future. We hope you'll continue to build your awareness of energy use, and to help turn off lights and heat in a room when no one is around.

During the campaign, we noticed a few interesting approaches around residence:

  • One suite downsized to 3 fridges instead of 4.
  • One suite used flash lights most of the time!
  • Most washing machines were set at the cold water setting.
  • Posters and post-it notes were everywhere for reminders.
  • Most suites turned their temperature down or off.
  • Lights were turned off when no one was around.
  • And there was so much more. If you have a story to tell please contact us.

January 2010 Competition Details

This kick-off competition has two ways to win. Both are described below, as is the process for establishing baselines for comparisons. It is possible for the same House to win both prizes.

Biggest Overall Reduction

The house that has the biggest reduction in electricity consumption during the competition period (January 18 - 31) will be the winner. The reduction compares the electricity consumption for a given house during the competition period, against the baseline consumption for that same house. Each house is effectively competing against itself. The baseline will be calculated as the average total consumption (kWh) for each house during the baseline period. Prize for the Biggest Overall Reduction will be a House dinner outing to Boston Pizza.

Biggest Single Daytime (8am - 5pm) Reduction

The house with the biggest daytime (8am to 5pm) reduction on any single day during the competition period will also win a prize. The baseline will be calculated as the average consumption (kWh) between the hours of 8am and 5pm for each house during the baseline period. The day with lowest daytime consumption for each house will be compared against the baseline average for that house. The house with the biggest single daytime reduction will be the winner. Prize for the Biggest Single Daytime Reduction will be a House Snowtubing Pass to Mount Seymour.

Establishing a Baseline

January 4 - 11 serves as a baseline period. The baseline provides a levelling mechanism to allow for differences in inherent energy efficiency between the different residence houses. During the baseline period the electricity consumption for each house will be monitored and an average consumption will be established as the baseline for each house.

For the Overall Biggest Reduction, an Baseline Average for overall total energy consumption (kWh) was calculated for each House during the Baseline Period. At the end of the competition period each House will be measured against it's own baseline. The House with the biggest reduction between their overall energy consumption during the competition and their baseline, will be the winner.

For the Biggest Daytime Reduction competition, a Daytime (between 8am and 5pm weekdays) Baseline Average was calculated for each House during the Baseline Period. At the end of the competition, we'll select the day with the lowest consumption for each house (it can be any weekday). The house with the biggest reduction between their lowest single daytime (8am to 5pm) consumption during the competition and its baseline is the winner.

October and November 2010 Competition Winners

On the graphs, the vertical axis represents cumulative savings as compared to each individual House's baseline. Positive numbers represent usage savings under the baseline amount whereas negative numbers represent usage costs over the baseline amount. All dollar values are theoretical and based on sample Time Of Use pricing intended only for this competition.

October 1-31, 2010

The October 2010 competition is over! Congratulations to all the Houses who managed to reduce their peak energy use to get in the black over the month of October. The winning house was Nootka with a total simulated savings of $344.39! The runner up was Haida with a total simulated savings of $211.69!

The leading Houses earned a lot of credit for shaving their morning peak energy consumption, when the time-of-use prices were highest (20 ¢/kWh).

Congratulations to Nootka for all their hard work. Best of luck to everyone in the new November competition. Remember, everyone is starting from scratch with new baselines!

November 1-30, 2010

The November 2010 competition is over! Congratulations to all the houses for reducing their peak energy throughout most of the month.

The winning house was Salish with a total simulated savings of $770.69! Salish house shaved an average of 30% off their energy consumption during morning peak hours through the month of November, and also achieved the greatest single-day peak reduction of 48% below baseline during morning peak hours on November 19th.

The runner up was Nisga'a with a total simulated savings of $475.51!

The leading Houses earned a lot of credit for shaving their morning peak energy consumption, when the time-of-use prices were highest (20 ¢/kWh).

October and November 2010 Competition Details

The October and November 2010 REAR Competition was titled "Conquer Your Peaks!". The goal of the competition was to be the house that reduced energy the most over each competition month, but with energy savings weighted with a Time-Of-Use Tariff, that is, an energy price that is higher during times of the day when electricity consumption peaks. The house with the greatest TOU-weighted energy cost savings won the competition.

For purposes of the "peak-shaving" competition, we had the energy management system web portal display energy consumption in peak and mid-peak hours with red or orange consumption-level bars on the consumption chart, conveying the urgency of reducing energy consumption during those hours.

We also displayed the different prices of energy consumption at different times of the day:

Weekdays
  Period Time ¢/kWh
     on-peak 6am-9am 20
     mid-peak 5pm-8pm 10
     off-peak 9am-5pm
8pm-6am
5
Weekends
     off-peak all day 5

These were artificial electrical energy prices set up just for the purpose of the competition.
