Since its official launch on May 28, 2015, the Department of Energy's Interior Lighting Campaign (ILC) has signed up companies such as Yamaha Motor Corporation, Target, Kohl's Department Stores, and Macy's to join the steadily increasing ranks of companies looking to reduce their energy bills through high performance indoor lighting improvements. The campaign currently has more than 85 supporters.

The goal of the ILC is to replace traditional troffer lights—modular lighting fixtures that fit into dropped ceiling grids— found in U.S. commercial buildings with at least 1 million highly efficient troffer lighting by May 2016. Building owners and managers can save up to 60 percent in lighting energy costs when replacing less efficient troffers with new ones, and up to 75 percent of lighting energy by adding controls such as dimmers, timers, and occupancy sensors.

The ILC website offers a wealth of information and resources, including Version 5.0 High Efficiency Lighting Troffer Performance Specification. "If every troffer in the U.S. was replaced with troffers that comply with this specification, the nation could save approximately 4 billion dollars in energy costs, annually," said Linda Sandahl, PNNL senior project manager for the ILC.

The specification, published by the Better Buildings Alliance with support from DOE's Buildings Technologies Office, provides building owners and managers with a description of troffer requirements that will result in energy and cost savings, as well as reliable performance. It can be found on the ILC website along with other resources for building owners and managers who join the campaign.

Technical efforts were led by Pacific Northwest National Laboratory in collaboration with the Better Buildings Alliance Lighting & Electrical Team, ILC organizers, and with input from lighting manufacturers.
