How can an Energy Auditor determine if a client
would benefit from upgrade lights and new
appliances?

•  
•  
•  

• Do a Lighting Appliance assessment

6
Lighting Appliance assessment

• Start by gathering information
• Which appliances do they have and where? (Any
  refrigerators in the garage)
• How old is the appliance?
• How much do they use the lights or appliances?
• Measure, when possible, how much energy it
  actually uses
•  
•  
•  

7
Lighting

• Lighting in the home is provided by using
  electric lights, or by natural daylight through
  windows and skylights.
• For energy savings incandescents and halogens
  should be replaced with CFLs LEDs (where
  possible)

     
8
Lighting Compact Fluorescent Lamps

• They use ¼ the energy and last 10 times as long
• They come in varied color renderings full
  spectrum, bright white, golden
• They give off 1/2 the heat of an incandescent or
  halogen bulb

     
9
Lighting LEDs

• Light Emitting Diodes (LED) They consume 3 to 5
  watts for the same light levels as a 13 watt CFL
  and 60 watt incandescent
• Unfortunately, they cost 20 to 30/bulb
• They will continue to improve and come down in
  cost.

Overview of Appliances

• Common residential appliances
• Refrigerators/Freezers
• Ovens, Stoves
• Space Heaters
• Dishwashers
• Clothes washers/dryers
• TVs
• Computers
• Audio/Visual
•  
•  
•  

11
Taking an Inventory of Appliances

• So once youve determine how many appliances
  where they are, whats next
• Age
• Model number (too look up estimated consumption
• Talk with owner how much they use it
  (dishwashers, etc.)

•  
•  
•  

12
Refrigerators/Freezers if it is pre-1990replace
it!

• Refrigerators built before 1990 may use 1200 to
  1500 KWH/year (150 to 180/year)
• Energy-Star refrigerators will only use 400 to
  500 KWH (48 to 55/year)
• Ask the homeowner, how much are they willing to
  pay to cool that 6-pack of beer in the garage?

•  
•  
•  

13
Televisions solid, state, plasma LCD

• Solid state (tube) TVs use 75 to 300 watts on
  and 5 watts off
• Plasma TVs can use upt 1000 watts on and up to
  100 watts off!
• LCD TVs use 100 to 300 watts on and 5 to 10
  watts off
• Look for Energy-Star label beware of
  phantom-loads

•

14
Computers Laptop vs. Tower watch out for
Phantom-Loads

• Solid state (tube) TVs use 75 to 300 watts on
  and 5 watts off
• Plasma TVs can use upt 1000 watts on and up to
  100 watts off!
• LCD TVs use 100 to 300 watts on and 5 to 10
  watts off
• Look for Energy-Star label beware of
  phantom-loads

•  
•  
•  

15
Stoves, Ovens natural gas orelectric? Plus,
microwaves

• Electric stoves will use 400 to 600 KWH/year
• Natural gas stoves will cost 1/3 (even with
  current energy prices)
• Microwaves use 900 to 1300 watts this is still
  less than ½ what the electric stove will use

•  
•  
•  

16
Space Heaters the energyhog waiting inside

• Electric space heaters run at 1500 Watts
• If this runs 8 hours a day for 60 days over the
  course of the winter will cost 100/winter
• Assess how the house can be made more
  efficient/comfortable to avoid using the unit

•  
•  
•  

17
When possible, measure dontestimate

• Doing short-term electrcity monitoring will show
  the homeowner how much an appliance uses/costs
• The homeowner can also afford to buy these (90
  to 250) so they can track appliances around
  their home

Career Opportunities

• Governor Ritters New Energy Economy rising
  costs for Natural Gas Electricity is increasing
  demand for energy auditors
• Residential Energy Auditors have been around
  since the 1970s but it has been a small industry
  nationwide in Colorado
• Governor Ritters New Energy Economy rising
  costs for Natural Gas Electricity is increasing
  demand
• With buildings consuming more than 1/3 of all
  energy in the U.S. each year, they are a
  significant source of Global Warming emissions

22
Career Opportunities

• Governor Ritters New Energy Economy rising
  costs for Natural Gas Electricity is increasing
  demand for energy auditors
• As a part of this, Xcel Energy Aquila Power
  must prove significant Energy-Efficiency
  Renewable energy enhancements between now and
  2020 20 of power must come from renewables or
  nega watts
• Energy Auditors are first on the scene to assess
  energy problems and prescribe solutions
• House-as-a-System knowledge is needed to identify
  the problems and even to optimize the
  installation of renewables
