Annual Energy Cost Savings Estimator
Use this 3-part calculation to determine annual energy cost savings resulting from an upgrade of one lamp or system type throughout a facility. This potential annual cost savings figure may be compared with the cost of the upgrade to determine simple payback and return on investment (ROI). NOTE: For fluorescent systems, substitute “lamp” with “system” or “fixture” so that ballast watts are included.
