Use this Excel-based tool to create an assessment of how much you can save by upgrading your current lighting to more energy efficient alternatives. The calculator can estimate the incentives you can earn and analyze the cost-benefit of potential projects.

In addition to the money-saving and incentive-earning estimates the calculator generates, there are other benefits of efficient lighting that are not included here. The calculator does not account for the impacts from better lighting quality, reduced lighting maintenance costs and other benefits of more efficient lighting.
