Introduction
  • Thank you
  • Credits!
  • My Opinion
  • Schedule

EMP Seminar Outline
  • Todays Schedule
  • Before you begin the EMPask who, what, when,
    why, how.
  • First Stepscreate the team, gather materials.
  • Next Steps benchmarking, and energy audits.
  • Study the findings and make recommendations.
  • What will it cost? What will it save?
  • Finally, pulling it all together

Why do we need an EMP?
  • December 1, 2005
  • Electricity costs to skyrocket
  • By DAVID SCHOETZSTAFF WRITER
  • BARNSTABLE - The cost of the electricity supply
    for Cape Cod and Martha's Vineyard
  • homeowners will increase by 81 percent starting
    with December meter readings.
  • The cost of the actual electricity on residential
    bills will climb from 7.132 cents per kilowatt
    hour to 12.92 cents.
  • (Cape Cod Times)

Why do we need an EMP?
8
What if?
  • What if you are asked to develop an Energy
    Management Plan? Is it Mission Impossible?

9
Before you begin
  • Who wants the report?
  • Why do they want it?
  • When do they want it by?
  • What language do they speak?
  • How much do you want to spend?

10
Before you begin
Form a team! Choose wisely!
11
Before you begin

Who should be on your Dream Team?
12
First Step
  • Meetings
  • Invite only those who need to be there
  • Send them an agenda ahead of time
  • Start on time
  • Stick to the agenda
  • Take notes
  • Assign action items everyone should get one
  • Adjourn on time
  • Issue minutes

13
First Step
  • Gather Materials
  • Energy bills All fuels for at least 3 years.
  • Graphs! Pictures are truly worth 1000 words.
  • Drawings Both building and equipment.
  • Physical descriptions, occupancy patterns, age,
    etc.
  • Pictures!
  • Specifications (if available) for all major
    equipment.
  • Preventative Maintenance program summary.
  • Written OM Procedures.

14
First Step
15
First Step
16
Next Steps
  • Benchmark
  • Compare your buildings to each other and similar
    facilities.
  • Good performers?

What Does a Rating Tell us?
20
Employing Portfolio Manager
  • Screening tool
  • Identify poor performing buildings in need of
    improvements
  • Scoping Tool
  • Use the generated score to determine course of
    action
  • Evaluation Tool
  • Track and measure building improvements
  • Energy Management Tool
  • Monitor building performance over time
  • Track building performance across all facilities

21
Determining a Course of Action
22
Before You Start Collect Data
  • Mandatory Data Needs
  • Zip code (to normalize data for weather)
  • Gross square footage of facility (includes
    secondary spaces)
  • 1 year of energy data (all fuel types)
  • Helpful Data
  • (defaults may be used in lieu of this info to
    generate a rating)
  • Number of occupants
  • Number of PCs
  • Others (depending on space type)

Next, the Energy Audit
  • Energy Audits walk through vs. comprehensive
    energy audits
  • Smoking guns? Ask your team!
  • What can your utility tell you?
  • COM Check at www.energycodes.gov for code
    compliance and energy power density
  • HUD Commercial Audit info at http//www.globalgree

    including labor, taxes, disposal, etc.
  • Sometimes, call in a contractor for a cost
    estimate.
  • Err on the high side.

44
Recommended Measures
  • Savings?
  • This should be the energy and if significant,
    labor savings.
  • When possible, have someone check your numbers.

Why?
When?
one manufacturers 700 series T8 lamp is rated
at 2800 lumens, while the high performance
version carries an initial lumen rating of 3150
lumens, a 12.5 improvement. The Super T8 lamps
make use of improved phosphor technology, so they
stay brighter over time. Lastly, better phosphor
increases the color rendering index of Super T8
lamps to 85 vs. 75 for standard T8 lamps.

DCV Savings? Occupancy fluctuations in retail
stores and other commercial facilities can amount
to as much as 1.00 per square foot (ft2).
DCV Costs? CO2 sensor technology has improved
substantially in recent years, and prices have
dropped dramatically. From more than 800 to as
low as 200, and several manufacturers offer CO2
sensors bundled with temperature and humidity or
dew point sensors in the same housing, which
further reduces total costs.

ECO 12 - VFDs Considerations
  • Some forward curve fans are not suited for VFD
    operation due to specific fan curve
  • Savings in applications with high static pressure
    could be very small
  • Some old motors can not be driven by frequency
    varying devices
  • Inverter duty motors are best suited for VFDs
  • Applications that require high torque require
    special VFDs
  • Harmonic Distortion

  • Variable Speed Drives
  • Hospital kitchen exhaust fan 15 HP motor
  • Installed Cost - 9,400
  • Potential utility rebate - 1,250
  • Projected savings - 25 for 4h/d, 50 for 4h/d,
    75 for 4h/d
  • 48,000 kwhrs/yr 0.13 / kwhr 6,240
  • Payback with rebate (9,400 - 1,250 / 6,240)
    1.3 years
  • Rebates are subject to program criteria,
    availability of program funding and pre-approval
    by the utility.

ECO 13 EMS How It Works
147
ECO 13 - EMS Considerations
  • An EMS does not save energy! The proper use of it
    does.
  • EMS adds complexity to the HVAC system more
    problems to troubleshoot.
  • Compatibility/Proprietary Issues
  • Continuous commissioning / re-commissioning is
    critical

White vs Black Roof
149
ECO 14
White reflective roofs can lower attic
temperatures by up to 25-30 degrees F. Many
commercial buildings with central AC have ducts
in the attic where there is a significant amount
of heat gain. The white roof lowers the attic
temperature greatly increasing the air
distribution efficiency of the HVAC
system. Florida Solar Power Association

Expensive! Upside? Very efficient. Best for
supplemental applications. Rebate? Maybe.
