Simple ROI is calculated on product lifetime with the industry standard [ (Payback – Investment) ÷ Investment ×100] formula. Cost may be full direct if retrofit, or may be difference (Original - New) if complete new installation. Include ALL COSTs and verify calculations before implementing a solution.
I need to put together a cost estimate for a street light system. I have all the cost data I need, except wire size to service the lights. I'm unsure how to use the lamp power requirements to determine the correct wire size so I can price the materials.
If you are not sure, use the $6 per bulb figure listed in the formula above. That is an established industry average. While you may think it costs nothing, if you really sit down and do a talley of bulbs, ballasts, down time, lift rental, safety, and labor, you will find the $6 figure a pretty close average.
Many workplanes are not perpendicular to the direction of light intensity, which is why calculating light level at a point is useful for such applications. In these cases, we often must determine light levels on workplanes that are not horizontal and perpendicular but tilted or even vertical. For tilted-horizontal or vertical planes:
The $15M overall cost includes the study. Public Utilities will pay for the $1M study now from electric fund budget, and recover the cost in street light rates. The bulk of the project cost (estimated at $12,319,000) would be reimbursed by Greenhouse Gas (GHG) Allowance Auction Proceeds based on GHG reductions achieved by the project.
Enter LED and CFL light fixtures. These light bulbs are becoming very popular for their energy savings and longevity, but they do cost more than an incandescent light fixture. The energy cost calculator can estimate how long it will take to pay for an LED/CFL upgrade based on the amount of usage, electricity costs, and the number of lamps needed.
