Status: Complete

Project Description: Implement an energy competition between Greek Houses within the Cal Greek Community as a way to complete small scale retrofits and reinforce & promote sustainable behaviors within the Greek system.

Goals: Have 24 Greek Houses with over 1200 students participate in a semester-long energy competition. Implement a pledge that house monetary savings from the energy competition will go to the sustainability chairs’ budgets. Reduce kWh used in houses by 10%. Save 133,490.4 kWh of electricity and avert 37,243.82 kg CO2e and save 110,594 gallons of water and avert 442.38 kg CO2e through CFL exchanges, energy conservation behaviors, shower head retrofits, occupancy sensor installations.

2011-2012 Accomplishments

  • 18 fraternities and sororities competed in the Green Cup competition. Green Campus and Greening the Greeks educated sustainability chairs in each house on energy saving procedures who then motivated members of their houses to save energy.
  • Houses were offered $200 sustainability retrofit budgets. 4 houses took advantage of these retrofits amounting to $807.58 spent.
  • Created baseline calculations for energy consumption based on the house's previous energy bills for the same two months.
  • 29,221.17 kWh of electricity and 667.33 Therms of natural gas were saved.
  • The winning house was Fiji fraternity, which saved 63.47% energy over its original baseline, followed by KA fraternity, which received an honorable mention for 61.52% energy savings.
    • Fiji received $2500 for house energy retrofits.
    • KA received $500 for house energy retrofits.

Green Cup 2011 Results

  • Green Cup presented at the 2012 Green Campus Energy Efficiency Summit.
  • Green Cup was awarded "Best Student Energy Efficiency Program" at the California Higher Education Sustainability Conference. View Green Cup's Best Practices presentation at CHESC 2012 here

2012 Year-End Report

Next Steps: The Green Cup Team managed to save $4,932 from the TGIF grant, allowing the team to run a second competition in Fall 2012. The Green Cup Team will continue to collaborate with Greening the Greeks and be more proactive in assisting houses with their sustainability retrofits so that more Houses will take advantage of the available retrofit budgets.  

2012-2013 Accomplishments

  • PowerSave Campus developed a Green Cup page on the PowerSave website.
  • Winners of the 2011 Competition, Fiji and KA, selected their retrofits for use of the prize money. Fiji chose to improve the efficiency of its HVAC system and KA chose to install chimney dampers. 
  • Twenty-four houses signed up to compete in the 2012 Green Cup Competition.
    • Competing houses were required to submit baseline energy data. 
    • Houses who submitted their data received an initial budget of $200 for house retrofits. An estimated 14 houses took advantage of this retrofit budget.
      • Retrofits include replacing incandescents with CFL's, using drying racks, timers for televisions, sink aerators, and weatherstripping.
    • PowerSave Campus will be monitoring the retrofit process and assist with the installations.
  • PowerSave Campus and TGIF developed a How To: Organize and Run a Greek House Energy Savings Competition Guide.

2012 Green Cup Competition Results

Green Cup Competition has saved an average of 143,883.885 kWh and 3580.82 therms per semester (Fall 2011 and Fall 2012) resulting in total cost savings of $27,725.31.

Mission Statement

The Green Initiative Fund (TGIF) provides funding for projects that reduce UC Berkeley's negative impact on the environment and make UC Berkeley more sustainable. TGIF will allocate funds to projects that promote sustainable modes of transportation, increase energy and water efficiency, restore habitat, promote environmental and food justice, and reduce the amount of waste created by UC Berkeley. Portions of the fund also support education and behavior change initiatives, student aid (via return to aid), and internships. TGIF is supported by student fees and administered through a student-majority committee and a program coordinator.
