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


Energy reduction efforts1

Energy Reduction Efforts

  • How Did We Do It?

-Energy Performance Contracts

-Temperature Control Reductions

-Retro Commissioning

Energy Reduction Efforts

  • Dollars Saved Compared 2005 to 2011

  • 2005248,639,864=72,872,176 KWH x $.088 = $6,412,751

  • 2006231,703,193=67,908,321 KWH x $.088 = $5,975,932

  • 2007207,403,347=60,786,444 KWH x $.088 = $5,349,207

  • 2008196,067,563=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

  • 2011158,002,092=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

Energy Reduction Efforts

  • Environmental Impact

    125,165 TONS of Carbon Dioxide (CO2) NOT EMITTED INTO THE ATMOSPHERE.

  • THIS IS THE RIGHT THING TO DO!


Energy performance contract

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


Energy performance contract1

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


Energy performance contract2

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


Energy performance contract3

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


Energy performance contract4

Energy Performance Contract

  • Phase II – Update

    • Schedule:

      • Audit CompletionNovember 24, 2010

      • Approval CompletedJanuary 14, 2011

      • Start WorkJune 9, 2011

      • Completed WorkMay 30, 2012


New future energy reduction efforts

New & Future Energy Reduction Efforts

  • Continue to Implement Energy Management Plan

    • Road Map to Comprehensive Energy Management


New future energy reduction efforts1

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


New future energy reduction efforts2

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
