WHY DO AN ENERGY AUDIT?
Why Do An Energy Audit?

• Knowing is half the battle
• Prioritization of savings measures
• Self Generation
• Broad vs. targeted audits

3
ENERGY AUDIT PROCEDURE
Energy Audit Procedure

• EVALUATE EXISTING ENERGY CONSUMPTION
• IDENTIFY SAVINGS MEASURES
• REPORT RESULTS
• INSTALL, ENABLE, EDUCATE ON SAVINGS MEASURES
• FOLLOW-UP

4
Basic Tools for the Audit

• MARKETING MATERIALS
• WATT METERS
• BALLAST CHECKERS
• SPREADSHEET/
• REPORT TEMPLATE
• LIST OF RECOMMENDATIONS
• SOCIAL MARKETING PIECE

Energy Vs. Power

• Watts (W) and kilowatts (kW)
• measure power, or the rate
• at which electrical work is performed.
• Watt-hours (Wh) and kilowatt-hours (kWh) measure
  energy, or the quantity of electricity used.
• Demand is measured in watts, Consumption is
  measured in watt hours.
• Estimate how many hours a day the device is used
  in a given period of time such as one month.
  Multiply this by kilowatts to determine
  kilowatt-hours (kWh).
• W/1000 x hours of use kWh

ENERGY COSTS
USING kWh TO FIGURE COSTS AND GHG 0.11-0.18 per
kWh (CA) 1.3 lbs CO2 per kWh (US) 0.805 lbs CO2
per kWh (CA, CCAR) 0.524 lbs CO2 per kWh (PGE)

Over 50 of the power generated at the plant
can be lost before it makes it to the end user!

Using a Watt Meter
Plug device into the watt meter (and the watt
meter into the wall outlet) to get accurate
power, energy, phantom load and energy cost
data.

PLUG LOAD RECOMMENDATIONS

• Behaviors
• Controls
• and Operations
• Upgrades and
• Retrofits
• Eliminate
• Redundancies

Zero to Low Cost Measures for Schools
Zero to Low Cost Measures

• Enable Energy Saving Settings on all Computers
  and Photocopiers
• EZ GPO Network Based Power Management from
  ENERGY STAR
• VENDING MISERS on vending machines and/or
  removing lamps
• Power Strips to manage phantom loads
• CFLs for task lighting
• LED exit signs
• Check outdoor lighting timers
• Motion sensors for bathroom lighting
• Review scheduling of night/ weekend classes
• ??? Be Creative!

CAMPUS LIGHTING SYSTEMS

• Components of lighting systems
• Lamps (fluorescent, incandescent, halogen)
• Ballasts (8 - 20 of the energy!)
• Fixtures
• Controls
• Adjustments to any of these components can save
  energy!

T8 VS. T12
CRI Color Rendering Index. The higher the
CRI, the more natural objects will appear under a
light source ?Based on 0.12/kWh at 3,000
hrs/year operation
16
COMPACT FLUORESCENTS

• Compact fluorescent lamps are a terrific
  replacement for incandescents. They provide the
  same amount of illumination for 3 - 4 times less
  energy.
• Though they are more expensive, they last 10 - 15
  times longer, with life spans that range between
  10,000 - 20,000 hours.

17
LIGHTING CONTROLS

• Switches Manual, Dimmer, or Combination
• Occupancy sensors - infrared and ultrasonic
• Photo sensors (can work w/ day-lighting)
• Timers - mechanical and electronic

18
LIGHTING RECOMMENDATIONS

• Replace older fluorescent systems (T12 Magnetic)
  with more efficient (T8 Electronic) lamps
  ballasts
• Convert incandescent fixtures and lamps to
  fluorescent fixtures and lamps
• Use task lighting to minimize overhead lighting
• Maximize day-lighting
• Regular cleaning, replace diffusers
• Turn off lights when not needed, and/or use
  automatic controls
