Online energy-savings calculator

WattStopper's free, Web-based energy savings calculating tool allows users to identify lighting control strategies that best match energy-savings goals for new construction or retrofit projects. Quick and Full Assessment levels offer savings information for either a single room or an entire building with lighting controls. If desired, users can retain data for reference on future projects. The Energy Calculator provides a list of the manufacturer's predefined Lighting Control Measures, which define various levels of automatic light shut-off. Calculated energy savings percentages are based on research from organizations including the U.S. Department of Energy and Environmental Protection Agency. Future versions of the tool will include calculations for plug/receptacle load, daylighting and time-based controls.
