The calculator compares energy savings and paybacks for common lighting control strategies and will help you make informed decisions for "Putting a Stop to Energy Waste™" using products from WattStopper.

It only takes a few minutes, using the Quick Assessment, to see the potential energy savings* for a lighting system retrofit or a new construction project. Start with entering the basic luminaire and lamp data to establish your baseline energy use. Then select from several Lighting Control Measures (LCM's) to determine which lighting controls are best for your lighting project. The additional energy savings from using lighting controls is calculated and simple paybacks and costs are presented.

To confirm your lighting plan, do a Full Lighting Assessment. The result is complete documentation that includes anticipated savings using lighting controls and updated lighting, anticipated energy usage and ROI for an entire building.

Look to more functionality in future versions of this handy tool that will include calculations for day lighting and time-based controls.
