Compressed Air Best Practices - January 2009 - (Page 27) Focus Industry ENERGY REBATES | 01/09 | 6. Is ambient light available from windows or skylights, which may allow the light fixture to be off during sunlight hours? (reference photos #6 and #7) Is the light level reduced in non-precision work areas such as walkways and storage when compared to workstation areas? 7. Step #2: Determine Existing Energy Costs The second step is to determine the value of changing the status of the existing light fixtures. For this example, I will consider the 440-watt Metal Halide light fixtures, which are commonly used, in many industrial facilities. The current energy cost of the 125 Metal Halide light fixtures is $46,563 per year. Calculation: # of Fixtures x watts per fixture/1,000 x hours on per week x weeks per year x $/kwh = $/year 125 x 440 watts/1,000 x 166 hours/week x 50 weeks per year x $0.102/kwh = $46,563 /year #5 Lights on without workers and excessive lighting in non-work areas. Step #3: Determine the Correct Amount of Light: There were 60 fixtures, which could be moved closer to the work area. By moving them closer, we were able to eliminate 20 fixtures resulting in an energy savings of $7,450. Calculation: # of Fixtures x watts per fixture/1,000 x hours on per week x weeks per year x $/kwh = $/year 20 x 440 watts/1,000 x 166 hrs/week x 50 weeks per yr x $0.102/kwh = $7,450 /year #6 A simple light sensor can shut down lights when the sun is shining www.airbestpractices.com 27 http://www.airbestpractices.com
