You can achieve 100% Energy Saving WHEN YOU TURN OFF THE LIGHTS

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

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 Efforts
• How Did We Do It?

-Energy Performance Contracts

-Temperature Control Reductions

-Retro Commissioning

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