DOE Evaluates Tunable-White Classroom Lighting

In May 2019, the Department of Energy (DOE) published a Pacific Northwest National Laboratory (PNNL) report evaluating a trial installation of tunable-white lighting systems at three classrooms in an elementary school in Folsom, California. Using monitoring, the researchers found the new LED lighting generated 46% energy savings compared with the existing fluorescent system at full output, while producing similar light levels. Energy savings increased to 48% to 69% during a typical day based on how teachers used the controls. Teachers valued the ability to dim the lights and change color output via tuning.
