Typical Lighting Retrofit Existing Lighting Room 330 The existing lighting consisted of (20) flourescent fixtures each using (4) 4 foot fluorescent lamps and (2) magnetic ballasts. Ballasts are required in all fluorescent fixtures to provide the proper voltage and current to operate the lamps. The flourescent lamps were each 34 watts, while each ballast used aproximately 12 watts. The total wattage per fixture was 160 watts. Cost to Operate the Existing Lighting System The total wattage of the existing lighting system is: 20 fixtures x 160 watts = 3,200 watts or 3.2 Kilowatts (KW) The estimated hours of operation of these fixtures is: 10 hours/day x 5 days/week x 42 weeks/year = 2,100 hours The average electric rate for MGE is about 0.06 $/kilowatt-hour (KWH), therefore the annual cost to operate these fixtures is: 3.2 KW x 2,100 hours x 0.06 $/KWH = $403.20 LIGHTING RETROFIT PROJECT The lighting retrofit project implemented by Honeywell consisted of replacing the (4) fluorescent lamps and (2) magnetic ballasts with 2 energy efficient T8, 1î diameter, lamps, an energy efficient electronic ballast and an aluminum reflector installed behind the lamps in order to improve the efficiency of the fixture by maximizing the amount of light the fixture produces. The total wattage of the retrofit fixtures is 58 watts. The estimated cost to retrofit this room was $1,400 Cost to Operate the New Lighting System Determine the annual savings from this new system. Show your work. Total wattage (in KW): Annual cost: Annual Savings from original: How many years will it take to pay off the cost of the new system?

Electricity Audit of Your HomeElectricity Audit of Your Home Analyze the amount of electricity used in your home. Choose one

room that has the greatest number of appliances and lights to use for the audit (You may do two rooms for up to 10 points extra credit). Create a data table showing the name of the room, appliances, wattage for each appliance, hours used per week, total watt-hours used per week and total KWH.

a. To determine wattage, look directly on the back or bottom of the appliance to get an accurate number. (Remember watts=volts x amps) Otherwise use the appliance survey sheet for assistance.
