1Making the case for energyefficiency 3 4. Why is Energy Management
Important? Good Energy Management is Good BusinessThe 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 Energy Waste in Commercial Buildings A
400% variation in energy use intensity of buildings in the
UnitedStates exists that is not explained by age, technology,
hours, size,climate. Little improvement of overall energy
consumption has been seenalthough building components are 30% more
efficient since 1980. Over-sizing of building fan systems, on
average, occurs by 60%. Most chillers are oversized by 50200%. -
EPA 5 6. Signs of Energy Waste in K12Buildings EPA/Energy Star
Statistics: The annual energy bill to run Americas 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 districts 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 effectiveenergy
management. Eastman Kodak saved more than $8.6 million in operating
costs in2002 from its energy management efforts. Fairfax County
Public Schools (VA)estimates an annual energysavings of $4.5
million (7.19%) from energy efficiency improvementson a $62.6
million utilities budget (FY: 2011-12) In 2001, the first year of
their Energy Management program, SandyCreek 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 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 charges8 9. 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. 9 10. EPAs Strategy

bills1. Anatomy of a Utility Bill2. Using Utility Data 13 14.
Anatomy of a Utility BillThanks to deregulation laws in NYS, our
primary utility bills(electricity and natural gas) are split into
two sections: DELIVERYSUPPLY Responsible for physical Provider of
the actual energydelivery of energy and usage Ex: NYSEG Solutions,
Directmetering. 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-Utility Bill Tracking and
Analysis (Monthly) Maintain a copy (physical or electronic) of all
utilitybills for use by the Facilities Department. Record monthly
billing data including unit cost,quantity and weather information
Compare usage to similar prior periods to identifymaintenance
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 buildings normalized performance vs. internal and
external peers Software/Service Examples: NYSERDAs Benchmarking

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

EPC agreements to go out a maximum of 18years. 5 to 10 year EPC
agreements are optimal Take advantage of SED $100,000.00 project
incentive. C&SCompanies of Syracuse has an innovative solution
calledNET ZERO that combines features of an EPC agreementwith five
$100,000.00 projects. Building aid + energysavings + grant money =
$0.00 cost to district for over$500,000.00 worth of projects.

as Designed Example 1: New school building with regular power
qualityproblems. Motors burning out, light fixtures failing
early.Two years after construction, it was discovered that a
powerconditioner was installed as part of the original
construction,but was never turned on. Example 2: Public school
built around 1975 with pneumaticcontrols, with consistently high
heating bills andincreasingly more difficult to control
temperature. Detailedphysical inspection of unit ventilators
revealed that in prioryears as pneumatic controls failed, the
outside air damperswhere 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

through the building and talk with tenants to determine if the
actual temperature is comfortable. Consider clothing worn during
that season Reduce (increase) temp. a min of 10 degrees F at night,
weekends and holidays during heating (cooling) season51 52.
