  3. 7-Step Energy Management Process Make the Commitment Assess Performance and Opportunities Set Performance Goals Create an Action Plan Implement the Action Plan Evaluate Progress Recognize Achievements

  4. Plug Load Overview Importance KEEPS On-site Energy Assessment Form Examples • Computer Power Management • Refrigeration Units • Beverage Machines KEEPS Plug Load and Computer Power Management Tool KEEPS Assessment Report

  5. Why is Plug Load Important? Plug Load (electronics & appliances) Easy to calculate usage and savings Easy to implement/install energy-saving measures Areas to focus for conservation • Computers • Beverage machines • Refrigeration

  6. On-site Energy Assessment Form

  7. Computer Plug Load Typically make up 40-55% of a school building’s plug load Varies between schools • Number of computers • Frequency of use

  8. Computer Power Management Free ENERGY STAR® software (EZ Wizard tool, EZ GPO tool) “Sleep mode” during inactivity “Wakes-up” computers temporarily for scheduled KDE updates Cost = Labor time for IT to write script and/or install software

  9. KEEPS Plug Load and CPM Tool:Computer Power Management Tab

  10. KEEPS Report Input Locate “Computer Power Management” in the KEEPS Assessment Report and modify respective figures and other necessary words/sentences for your specific school. Modify the inset box with the results calculated from the KEEPS Plug Load and Computer Power Management Tool.

  11. Plug Load Tab

  12. Beverage Machine Sensor Typical soda machine = $150-$200/yr Occupancy sensor turns off machine when vicinity is vacant. Maintains higher soda temperature unless vicinity is occupied Cost = $170/sensor • NEED subsidizes costs Savings = $45 - $140 each sensor Several year simple payback

  13. Beverage Machine Savings Calculations Formulas Beverage Machine(s) Cost/Yr. x 19% = Annual Savings Bev. Machine(s) MMBtu/Yr. x 19% = Annual Energy Savings Example School $498/Yr. x 19% = $95 Savings/Yr. 22.8 MMBtu/Yr. x 19% = 4.3 MMBtu Energy Savings/Yr.

  14. KEEPS Report Input Locate “Beverage Machines” in the KEEPS Assessment Report and modify respective figures and other necessary words/sentences for your specific school. Modify the inset box with the results calculated from the KEEPS Plug Load and Computer Power Management Tool

  15. Refrigeration Summer Shutdown Summer accounts for 20% of the year Typical K-12 school pays $500-$1,000 for refrigeration units Cost = labor to clean and unplug for summer Annual savings = $100-$200 Immediate simple payback

  16. Refrigeration Savings Calculations Formulas Refrigeration Cost/Yr. x 20% = Annual Savings Refrigeration MMBtu/Yr. x 20% = Annual Energy Savings Example School $872/Yr. x 20% = $174 Savings/Yr. 40 MMBtu/Yr. x 20% = 8 MMBtu Energy Savings/Yr.

  17. KEEPS Report Input Locate “Refrigeration” in the KEEPS Assessment Report and modify respective figures and other necessary words/sentences for your specific school. Modify the inset box by multiplying the total cost of refrigeration by 20% for estimated annual savings.
