Energy and Related Cost Savings:
( 460W ¨C 210W ) * 274 Fixtures = 68,500Watts
68,500 Watts * 24 hours/Day / 1000 = 1,644 kWh per Day Savings
1,644kWh/Day * 365 Days per year = 600,000kWh per Year
600,000kWh per Year * .08 rate = $ 48,000.00 /Year Energy Cost Savings
Plus: 274 Lamps * $ 21.00ea. = $ 5,754.00 /Year in Replacement Bulbs Costs
Plus: Labor to change Bulbs $ 2,500.00/Year
TOTAL Savings per year: $ 56,254.00
10 Years TOTAL Cost Savings $ 562,540.00 |
