• 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

• How Did We Do It?

-Energy Performance Contracts

-Temperature Control Reductions

-Retro Commissioning

• 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

• Environmental Impact

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

• THIS IS THE RIGHT THING TO DO!

• 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

• 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

• 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

• 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

• 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
