Making the case for energy
        efficiency


                             3
Why is Energy Management
           Important?

     “Good Energy Management is Good Business”

The evidence is clear that for both public and private k12
 schools, adopting an energy management strategy is a
 business decision you cannot afford to ignore.

Signs of Energy Waste in
         Commercial Buildings
 A 400% variation in energy use intensity of buildings in the United
  States exists that is not explained by age, technology, hours, size,
  climate.

 Little improvement of overall energy consumption has been seen
  although building components are 30% more efficient since 1980.

 Over-sizing of building fan systems, on average, occurs by 60%.


 Most chillers are oversized by 50–200%.

                                                                         5
Signs of Energy Waste in K12
            Buildings
 EPA/Energy Star Statistics:

    The annual energy bill to run America’s primary and secondary
     schools a staggering $6 Billion. $1 out of every $4 spent on energy by
     US schools is wasted. Conservative 25% = $1.5 Billion annually.

    Energy cost total between 1.5% to 3.5% of a typical school district’s
     annual budget. Energy is often second only to staff salaries – more
     than computers and textbooks combined.

    The least efficient schools use three times (3x) more energy than
     the best energy performers

    Top performing ENERGY STAR labeled schools cost forty cents per
     square foot less to operate than the average performers.

                                                                              6
Strong Energy Management
          = Real Savings
 Ford Motor Company has saved over $75 million through effective
  energy management.

 Eastman Kodak saved more than $8.6 million in operating costs in
  2002 from its energy management efforts.

 Fairfax County Public Schools (VA)estimates an annual energy
  savings of $4.5 million (7.19%) from energy efficiency improvements
  on a $62.6 million utilities budget (FY: 2011-12)

 In 2001, the first year of their Energy Management program, Sandy
  Creek CSD (NY) saved $300,000 on a $1.4 Million utility budget (~21%).
  Total of $2.7 Million in savings from 2001 to 2009.



                                                                           7
Pending Crisis
 Due to the recession, demand for energy supply is down,
 resulting in the lowest cost per unit of electricity in the last
 decade. Natural gas is also seeing record lows.
This is a TEMPORARY condition. Over time, usage demand
               will return and cost/unit will rise)

 Utility delivery (NYSEG, etc)companies are starting to shift
 rate structures to put a greater emphasis on peak demand
 usage. Over the next 5 years or so we can expect to see
 increasing peak demand charges and an elimination of the
 differential between day and night rates.
 When usage demand returns, we will be impacted by both
   increased cost/unit and increased peak demand charges

                                                                    8
Accessing Potential Lost Dollars
 By systematically implementing an Energy
 Management Plan, many school districts have been
 able to reduce energy consumption by 30% to 40%.

 The first 10% of reduction in energy use is possible
 with little or no cost.

 Defined heating /cooling set points and setbacks
 Defined access hours for midweek and weekends
 Defined path for requesting exceptions
 Adoption at the highest effective level of the District
 Identify local “Energy Champions”
 Easily measurable specific energy target (at the level of
  utility metering)
 Peer based energy targets – EPA Portfolio manager
  scoring, NYCHIPS,
                                                              11

 Understanding your district’s
         energy bills
1. Anatomy of a Utility Bill
2. Using Utility Data



                                   13
Anatomy of a Utility Bill
Thanks to deregulation laws in NYS, our primary utility bills
  (electricity and natural gas) are split into two sections:
           DELIVERY                            SUPPLY


 Responsible for physical          Provider of the actual energy
  delivery of energy and usage
                                    Ex: NYSEG Solutions, Direct
  metering.
                                     Energy, MEGA, etc.
 Owner of the power lines,
  gas piping and onsite meters
 Ex: NYSEG, RGE, etc.

                                                                     14
Potential Billing Issues
 Miscellaneous Charges
   Manual download charges on interval meters


 Demand Charges
    Do they appear to be reasonable ?


 Quantities and Volume
    Verify that the figures for kwh, KW and therms of natural gas
     agree between the supply and delivery companies. Electricity
     should be 1-to-1 and Natural gas should be +- 1.0%.

                                                                     15
Using Utility Data
-Utility Bill Tracking and Analysis (Monthly)

    Maintain a copy (physical or electronic) of all utility
    bills for use by the Facilities Department.
    Record monthly billing data including unit cost,
    quantity and weather information
    Compare usage to similar prior periods to identify
    maintenance issues, etc.
    Software Tools:
        MS Excel, EnergyWatchdog, SchoolDude/Utility Direct,


                                                                16
Using Utility Data
-Benchmarking (annually)

 Confirm savings   from energy conservation investments
 Compare a building’s normalized performance vs. internal
 and external peers
 Software/Service Examples: NYSERDA’s Benchmarking
 program, EPA Portfolio Manager

Renewable energy and
alternative technologies


                           18
Renewable Energy
              Pros and Cons
 Solar and wind make good educational demonstration
 projects

 Often fail to save significant amounts of energy and do
 not provide reasonable pay back periods

 Things to look for:
     Life of equipment/Maintenance schedules vs. payback periods
     Have we fully explored all other energy conservation options
      for our buildings?


                                                                 19
Alternative Technologies
Leading Edge vs. Bleeding Edge
         Leading Edge                     Bleeding Edge
 T8 & T5 lighting                  LED interior lights
 Modulating/Condensing             Heat reflective white roofing
    Boilers                         Waterless urinals
   HVAC control software           Geothermal heating and
   Occupancy controls (lighting     cooling
    & HVAC)                         CoGen
   LED lights (in some
    situations)
   Utility analysis software
   Co Gen
                                                                     20

Understanding funding
     opportunities


                        21
NYSERDA
 CFA – Consolidated Funding Application – A single
  application that streamlines access to NYSERDA’s Grant
  program and possibly additional funding from other
  NYS agencies.
 Existing Facilities

 FlexTech

 CHIPS 2.0 – High efficiency school building standard
  for both new and retrofit building projects
 New opportunities in 2012


                                                           22
NYSEG/RGE & National Grid
 NYSEG/RGE
   Existing Facilities - Small Business Energy Efficiency
    Program – Less than 100,000 kwh/month. < 70%
    materials & labor.

 National Grid
   Existing Facilities – Lighting – < 50% materials & labor


 All utility delivery companies offer a Custom Measures
  Program
                                                               23
Energy Performance
               Contracting
 SED allows EPC agreements to go out a maximum of 18
  years.
 5 to 10 year EPC agreements are optimal

 Take advantage of SED $100,000.00 project incentive. C&S
  Companies of Syracuse has an innovative solution called
  “NET ZERO” that combines features of an EPC agreement
  with five $100,000.00 projects. Building aid + energy
  savings + grant money = $0.00 cost to district for over
  $500,000.00 worth of projects.
 Consider a “self-directed” EPC
                                                             24

Operations & Maintenance
            Functioning as designed


            Calibrate thermostats


            Adjust dampers


            Janitorial services


                                       27
Functioning as Designed
            Retro-commissioning
            Regularly inspect all
            equipment and controls
            to ensure they are
            functioning as designed




                                      28
Functioning as Designed
 Example 1: New school building with regular power quality
  problems. Motors burning out, light fixtures failing early.
  Two years after construction, it was discovered that a power
  conditioner was installed as part of the original construction,
  but was never turned on.
 Example 2: Public school built around 1975 with pneumatic
  controls, with consistently high heating bills and
  increasingly more difficult to control temperature. Detailed
  physical inspection of unit ventilators revealed that in prior
  years as pneumatic controls failed, the outside air dampers
  where hardwired in the open position (either 100% or 75%
  open).
                                                               29
Calibrate Thermostats
           Periodically, walk
           through the building
           and compare the
           thermostat setting with
           a hand held digital
           thermometer
           (preferably with 2
           decimal places)
                                     30
Adjust Dampers
        Bring in the least
         amount of outside air
         necessary to maintain
         proper air quality

        Reduce outside air
         requirements by
         adjusting dampers to
         minimize the need to
         condition outside air
         (within codes)
                                 31
Janitorial Best Practices
                                           Team Cleaning
                                           Day Cleaning
                                           Coordinate Lighting
                                           Occupancy Sensors

    1 Making the casefor energy efficiency 3
  • 4.
    Why is EnergyManagement Important? “Good Energy Management is Good Business” The evidence is clear that for both public and private k12 schools, adopting an energy management strategy is a business decision you cannot afford to ignore. 4
  • 5.
    Signs of EnergyWaste in Commercial Buildings  A 400% variation in energy use intensity of buildings in the United States exists that is not explained by age, technology, hours, size, climate.  Little improvement of overall energy consumption has been seen although building components are 30% more efficient since 1980.  Over-sizing of building fan systems, on average, occurs by 60%.  Most chillers are oversized by 50–200%. • - EPA 5
  • 6.
    Signs of EnergyWaste in K12 Buildings  EPA/Energy Star Statistics:  The annual energy bill to run America’s primary and secondary schools a staggering $6 Billion. $1 out of every $4 spent on energy by US schools is wasted. Conservative 25% = $1.5 Billion annually.  Energy cost total between 1.5% to 3.5% of a typical school district’s annual budget. Energy is often second only to staff salaries – more than computers and textbooks combined.  The least efficient schools use three times (3x) more energy than the best energy performers  Top performing ENERGY STAR labeled schools cost forty cents per square foot less to operate than the average performers. 6
  • 7.
    Strong Energy Management = Real Savings  Ford Motor Company has saved over $75 million through effective energy management.  Eastman Kodak saved more than $8.6 million in operating costs in 2002 from its energy management efforts.  Fairfax County Public Schools (VA)estimates an annual energy savings of $4.5 million (7.19%) from energy efficiency improvements on a $62.6 million utilities budget (FY: 2011-12)  In 2001, the first year of their Energy Management program, Sandy Creek CSD (NY) saved $300,000 on a $1.4 Million utility budget (~21%). Total of $2.7 Million in savings from 2001 to 2009. 7
  • 8.
    Pending Crisis  Dueto the recession, demand for energy supply is down, resulting in the lowest cost per unit of electricity in the last decade. Natural gas is also seeing record lows. This is a TEMPORARY condition. Over time, usage demand will return and cost/unit will rise)  Utility delivery (NYSEG, etc)companies are starting to shift rate structures to put a greater emphasis on peak demand usage. Over the next 5 years or so we can expect to see increasing peak demand charges and an elimination of the differential between day and night rates. When usage demand returns, we will be impacted by both increased cost/unit and increased peak demand charges 8
  • 9.
    Accessing Potential LostDollars  By systematically implementing an Energy Management Plan, many school districts have been able to reduce energy consumption by 30% to 40%.  The first 10% of reduction in energy use is possible with little or no cost. 9
  • 10.
    EPA’s Strategy forCreating an Energy Management Plan  STEP 1: Make Commitment  STEP 2: Assess Performance  Step 3: Set Goals  Step 4: Create Action Plan  Step 5: Implement Action Plan  Step 6: Evaluate Progress  Step 7: Recognize Achievements 10
  • 11.
    Key Elements ofan Effective Energy Management Plan  District wide energy related mission statement  Defined heating /cooling set points and setbacks  Defined access hours for midweek and weekends  Defined path for requesting exceptions  Adoption at the highest effective level of the District  Identify local “Energy Champions”  Easily measurable specific energy target (at the level of utility metering)  Peer based energy targets – EPA Portfolio manager scoring, NYCHIPS, 11

    2 Understanding yourdistrict’s energy bills 1. Anatomy of a Utility Bill 2. Using Utility Data 13
  • 14.
    Anatomy of aUtility Bill Thanks to deregulation laws in NYS, our primary utility bills (electricity and natural gas) are split into two sections: DELIVERY SUPPLY  Responsible for physical  Provider of the actual energy delivery of energy and usage  Ex: NYSEG Solutions, Direct metering. Energy, MEGA, etc.  Owner of the power lines, gas piping and onsite meters  Ex: NYSEG, RGE, etc. 14
  • 15.
    Potential Billing Issues Miscellaneous Charges  Manual download charges on interval meters  Demand Charges  Do they appear to be reasonable ?  Quantities and Volume  Verify that the figures for kwh, KW and therms of natural gas agree between the supply and delivery companies. Electricity should be 1-to-1 and Natural gas should be +- 1.0%. 15
  • 16.
    Using Utility Data -UtilityBill Tracking and Analysis (Monthly)  Maintain a copy (physical or electronic) of all utility bills for use by the Facilities Department.  Record monthly billing data including unit cost, quantity and weather information  Compare usage to similar prior periods to identify maintenance issues, etc.  Software Tools:  MS Excel, EnergyWatchdog, SchoolDude/Utility Direct, 16
  • 17.
    Using Utility Data -Benchmarking(annually) Confirm savings from energy conservation investments Compare a building’s normalized performance vs. internal and external peers Software/Service Examples: NYSERDA’s Benchmarking program, EPA Portfolio Manager 17
  • 18.
  • 19.
    Renewable Energy Pros and Cons  Solar and wind make good educational demonstration projects  Often fail to save significant amounts of energy and do not provide reasonable pay back periods  Things to look for:  Life of equipment/Maintenance schedules vs. payback periods  Have we fully explored all other energy conservation options for our buildings? 19

    4 Understanding funding opportunities 21
  • 22.
    NYSERDA  CFA –Consolidated Funding Application – A single application that streamlines access to NYSERDA’s Grant program and possibly additional funding from other NYS agencies.  Existing Facilities  FlexTech  CHIPS 2.0 – High efficiency school building standard for both new and retrofit building projects  New opportunities in 2012 22
  • 23.
    NYSEG/RGE & NationalGrid  NYSEG/RGE  Existing Facilities - Small Business Energy Efficiency Program – Less than 100,000 kwh/month. < 70% materials & labor.  National Grid  Existing Facilities – Lighting – < 50% materials & labor  All utility delivery companies offer a Custom Measures Program 23
  • 24.
    Energy Performance Contracting  SED allows EPC agreements to go out a maximum of 18 years.  5 to 10 year EPC agreements are optimal  Take advantage of SED $100,000.00 project incentive. C&S Companies of Syracuse has an innovative solution called “NET ZERO” that combines features of an EPC agreement with five $100,000.00 projects. Building aid + energy savings + grant money = $0.00 cost to district for over $500,000.00 worth of projects.  Consider a “self-directed” EPC 24

    Operations & Maintenance  Functioning as designed  Calibrate thermostats  Adjust dampers  Janitorial services 27
  • 28.
    Functioning as Designed Retro-commissioning Regularly inspect all equipment and controls to ensure they are functioning as designed 28
  • 29.
    Functioning as Designed Example 1: New school building with regular power quality problems. Motors burning out, light fixtures failing early. Two years after construction, it was discovered that a power conditioner was installed as part of the original construction, but was never turned on.  Example 2: Public school built around 1975 with pneumatic controls, with consistently high heating bills and increasingly more difficult to control temperature. Detailed physical inspection of unit ventilators revealed that in prior years as pneumatic controls failed, the outside air dampers where hardwired in the open position (either 100% or 75% open). 29
  • 30.
    Calibrate Thermostats Periodically, walk through the building and compare the thermostat setting with a hand held digital thermometer (preferably with 2 decimal places) 30
  • 31.
    Adjust Dampers  Bring in the least amount of outside air necessary to maintain proper air quality  Reduce outside air requirements by adjusting dampers to minimize the need to condition outside air (within codes) 31
  • 32.
    Janitorial Best Practices  Team Cleaning  Day Cleaning  Coordinate Lighting  Occupancy Sensors 1. Joe Serna Jr (office building. Instituted day cleaning with hours from 11am to 8pm during 2001 energy crisis. Savings of 8% Total Building Energy 2. Johnson City School District saved 7.95% Total District Energy during fiscal 2010-2011 by time shifting their third shift cleaning staff. 32

Editor's Notes

  • #7 As school budgets get tighter, more people are realizing that many of the items on a typical school budget is not optional. Energy cost may be one of the last areas where adjustments can be made without compromising personnel compensation or quality of service.
  • #9 Natural gas wells are being capped. Power generation plants are being mothballed.
  • #29 Example 1: New School building with regular power quality problems. Motors burning out, light fixtures failing early. Two years after construction, it was discovered that the a power conditioner was installed as part of the original construction, but was never turned on.Example 2: Public school built around 1975 with pneumatic controls, with consistently high heating bills and increasingly more difficult to control temperature. Detailed physical inspection of unit ventilators revealed that in prior years as pneumatic controls failed, the outside air dampers where hardwired in the open position (either 100% or 75% open).
  • #31 Ensure thermostat setting equals actual space temperature
  • #32 Reduce outside air requirements by adjusting dampersto minimize the need to condition outside air (within codes)
