  1. STAFFORD COUNTY PUBLIC SCHOOLS ENERGY MANAGEMENT PROGRAM 2010 UPDATEBob Randall CEM, ,BEP, CBCPEnergy Manager You can achieve 100% Energy Saving WHEN YOU TURN OFF THE LIGHTS

  2. Overview • 2010 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 2010 4th Consecutive Year – School Division Reduced Utility Costs…. While the average cost of electricity decreased 14% from $.091 to an average cost of $.079 per KWH for all usage

  4. Energy Reduction Efforts 2010 • How Did We Do It? -Energy Performance Contracts -Temperature Control Reductions -Retro Commissioning

  5. Energy Reduction Efforts 2010 • Dollars Saved Compared 2005 to 2010 • 2005 248,639,864 = 72,872.176 KWH *$.0792= $ 5,771,476 • 2006 231,703,193 = 67,908.321 KWH *$.0792= $ 5,378,339 • 2007 207,403,347 = 60,786,444 KWH *$.0792= $ 4,814,127 • 2008 196,067,563 = 57,464,115 KWH *$.0792= $ 4,551,158 • 2009 172,592,046 = 50,583,835 KWH *$.0792= $ 4,006,240 • 2010 185,097,785 = 54,249,057 KWH *$.0792=$ 4,296,525 • WITH NEW SCHOOLS • 2007 246,594,352 = 72,272,670 KWH*$.0792= $ 5,723,995 • 2008 235,724,780 = 69,086,981 KWH*$.0792= $ 5,471,688 • 2009 217,896,755 = 63,861,885 KWH *$.0792= $ 5,057,861 • 2010223,409,383= 65,477,544 KWH*$.0792= $ 5,185,821 • From Dominion • 44,135,823 KWH ÷ $3,497,460=$.0792/KWH

  6. Energy Reduction Trend

  7. Energy Reduction Efforts 2010 • 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 • Recognized opportunity to reduce energy consumption by modernization of facility building systems through Energy Conservation Measures (ECMs) Lighting Occupancy Sensors Motors & Fan Drives Water Conservation • Utilized State Energy Performance Contract Program to evaluate, interview and select an energy performance contractor • Contracts are 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 • Estimated Completion October 2011

  10. Energy Performance Contract • Phase II – Update • In June 2010 NORESCO initiated Detailed Energy Audit • Survey of 8 school division facilities: Hampton Oaks ES , Park Ridge ES, Winding Creek ES, Drew MS, AG Wright MS, Brook Point HS, Mountain View HS, and the Professional Development Center • Four (4) energy conservation measures (ECM’s) • Audit Completion – November 24, 2010 • Approval process Completed - January 14, 2011 • Estimate Start Work – June 9, 2011 • Estimate Completion of Work- October 30, 2011

  11. Energy Performance Contract Energy Conservation Measures Selected • 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 You can achieve 100% Energy Saving WHEN YOU TURN OFF THE LIGHTS

  12. New & Future Energy Reduction Efforts • Implement School Division Energy Management Plan - Approved June 2010 - Road Map to Comprehensive Energy Management - Goals Utilize Performance Contracting Efforts where applicable Grow Energy Steering Committee participants ideas Develop a program to evaluate facility exterior envelopes Work with Operation Staff to fine tune facilities even more - Components Education Waste Reduction & Operational Guidelines Retro-Commissioning Monitoring & Reporting Sustainable Practices for Staff and Students

  13. New & Future Energy Reduction Efforts Retro-Commissioning Efforts • Retro-Commission at least one school per year • Completed BPHS in FY11 • DMS and PRES in FY12 Continue Holiday, Spring & Summer Break Temperature Control Measures Complete Energy Performance Contract (Phase II) Plan Energy Performance Contract (Phase III) Identified in FY11-16 CIP  Work with Rodney Thompson Staff to Construct a Wind Generator

  14. New & Future Energy Reduction Efforts Explore Use of Energy Education - Private Consulting Firm • Long Term Effort to Identify Unnecessary and/or Excessive Utility Consumption - Guarantees 20%+ Annual Savings • Cost Paid for from Savings Classroom Education - In coordination with Instruction Department Enhance Energy Education Opportunities

  15. New & Future Energy Reduction Efforts Questions? You can achieve 100% Energy Saving WHEN YOU TURN OFF THE LIGHTS
