5
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.

     
10
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
