Overview

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

6th Consecutive Year – School Division Reduced Utility Costs…

Energy Reduction Efforts

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 Reduction Efforts

-Energy Performance Contracts

-Temperature Control Reductions

-Retro Commissioning

THING TO DO!

Energy Reduction Efforts

History◦ Opportunity to reduce energy consumption by

modernization of facility systems through Energy Conservation Measures (ECMs)

LightingOccupancy SensorsMotors & Fan DrivesWater 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

Energy Performance Contract

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
