The U.S. Department of Energy (DOE) has published the final report from a demonstration retrofit of LED freezer case lighting in an Albertsons Grocery store in Eugene, Oregon. The Gateway demonstration report provides an overview of project results including: lighting performance, economic performance, and potential energy savings.
For the project, upright freezer cases were retrofitted with LED striplights. Occupancy sensors were also added to reduce electricity consumption. The lighting was compared against standard fluorescent lighting on the opposite side of the aisle.
