2. Overview • 2011 Energy Reduction Efforts • Energy Performance Contract Update • New & Future Energy Reductions Efforts You can achieve 100% Energy Saving WHEN YOU TURN OFF THE LIGHTS

3. Energy Reduction Efforts 6th Consecutive Year – School Division Reduced Utility Costs… While the average cost of electricity to SCPS rebounded 11% from $.079 to an average cost of $.088 per KWH for all usage

4. Energy Reduction Efforts • How Did We Do It? -Energy Performance Contracts -Temperature Control Reductions -Retro Commissioning

5. Energy Reduction Efforts • Dollars Saved Compared 2005 to 2011 • 2005 248,639,864 = 72,872,176 KWH x $.088 = $6,412,751 • 2006 231,703,193 = 67,908,321 KWH x $.088 = $5,975,932 • 2007 207,403,347 = 60,786,444 KWH x $.088 = $5,349,207 • 2008 196,067,563 = 57,464,115 KWH x $.088 = $5,056,842 • 2009 172,592,046 = 50,583,835 KWH x $.088 = $4,451,377 • 2010 185,097,785 = 54,249,057 KWH x $.088 = $4,773,917 • 2011 158,002,092 = 46,307,764 KWH x $.088 = $4,075,038 • WITH NEW SCHOOLS • 2007 246,594,352 = 72,272,670 KWH x $.088 = $6,359,994 • 2008 235,724,780 = 69,086,981 KWH x $.088 = $6,079,654 • 2009 217,896,755 = 63,861,885 KWH x $.088 = $5,619,845 • 2010223,409,383= 65,477,544 KWHx $.088 = $5,762,023 • 2011 196,071,320 = 57,465,216 KWH x $.088 = $5,056,939 • From Dominion • $3,288,210 / 37,443,980 = $.088 - KWH

6. Energy Reduction Efforts

7. Energy Reduction Efforts • Environmental Impact 125,165 TONS of Carbon Dioxide (CO2) NOT EMITTED INTO THE ATMOSPHERE. • THIS IS THE RIGHT THING TO DO!

8. Energy Performance Contract • History • Opportunity to reduce energy consumption by modernization of facility systems through Energy Conservation Measures (ECMs) Lighting Occupancy Sensors Motors & Fan Drives Water Conservation • Utilized State Contract to evaluate and select an energy performance contractor • Contracts funded through annual energy savings

9. Energy Performance Contract • History • Selected NORESCO for Phase I - 2006 • 18 Schools • 7 Energy Conservation Measures • Completed April 2007 • Selected NORESCO for Phase II - January 2010 • 8 Schools • 4 Energy Conservation Measures • Completed May 2012 • QSCB Bond Funded

10. Energy Performance Contract • Phase II – Update • June 2010 NORESCO initiated Detailed Energy Audit • Surveyed 8 schools: • Hampton Oaks ES • Park Ridge ES • Winding Creek ES • Drew MS • A.G. Wright MS • Brook Point HS • Mountain View HS • Professional Development Center

11. Energy Performance Contract • Phase II – Update • Selected 4 energy conservation measures (ECM’s) • ECM #1 - efficient lighting • ECM #2 - occupancy sensors in classrooms, (hallways, offices, gyms) • ECM #3 - water conservation (low flush) • ECM #4 - variable fan drives & efficient motors for HVAC equipment  • Estimated Annual Energy Cost Savings = $199,500.00 per year guaranteed

12. Energy Performance Contract • Phase II – Update • Schedule: • Audit Completion November 24, 2010 • Approval Completed January 14, 2011 • Start Work June 9, 2011 • Completed Work May 30, 2012

13. New & Future Energy Reduction Efforts • Continue to Implement Energy Management Plan • Road Map to Comprehensive Energy Management

14. New & Future Energy Reduction Efforts • Retro-Commissioning Efforts • Retro-Commission at least one school per year • DMS and PRES in FY12 Widewater ES in FY 13 • Continue Holiday, Spring & Summer Temperature Control Measures • Continue with fine tuning of our Temperature controls and upgrading them

15. New & Future Energy Reduction Efforts • Work with Planning and Construction on the new High School and Renovations. • Plan Energy Performance Contract (Phase III) Identified in FY13-17 CIP • Execute a Wind Generation Grant (RTMS) that will fund the Construction of a Small Wind Generator
