What is the Interior Lighting Campaign?
The Interior Lighting Campaign (ILC) is a recognition and guidance program designed to help facility owners and managers take advantage of savings opportunities from high efficiency interior lighting solutions. The initial campaign focus is on troffer lighting, with a goal to document upgrading of 1 million troffers to high-efficiency troffer systems by April 2017.
In early January 2017, ILC Participants surpassed this goal and are taking advantage of savings opportunities from high efficiency interior lighting solutions. Pledges for the new installation or retrofit of over 1.1 million high efficiency troffers, many with lighting control systems, have been made to date. Collectively, ILC Participants are expected to save nearly $13 million annually in electricity costs through energy use savings of nearly 123 million kWh annually across about 195 million square feet of building space.

Lighting system upgrades often represent some of the easiest, most cost-effective energy-saving opportunities available. By adopting more efficient troffer lighting, such as systems that meet the Better Buildings Alliance (BBA) specification for troffers, building owners can save more than 50% on a one-for-one basis, and up to 80% with the use of controls.
- Access to resources, including specifications, case studies, utility incentive lists, and educational webinars to help building owners make sound lighting decisions.
- Limited technical assistance
- Listing on the ILC web site. Those that show exemplary performance will be eligible for recognition.
- Organizations that don't directly own or operate facilities but support the goals of the ILC can join as Supporters, and receive recognition for their involvement.
How do I get involved in the ILC?
There are two ways to get involved in the ILC.
- Join the ILC as a Participant (e.g., site owner, manager, or operator) and make a pledge to review your current lighting portfolio and identify opportunities to upgrade to high-efficiency troffer lighting solutions.
- Join the ILC as a Supporter (e.g., utility, energy efficiency organization, ESCO, lighting designer/engineer, lighting manufacturer or distributor) and commit to promoting the Campaign to your customers or members, and communicate the benefits of joining the Campaign.
The overall luminaire efficacy must be at least 85 lm/W for projects planned prior to January 2017, and 105 lm/W thereafter. LED Troffers that meet either the Better Buildings Alliance Troffer specification or the DesignLights Consortium (DLC) Technical Requirements V4.1 meet the 105 lm/W requirement. Although the BBA specification and the DLC specification include color and warranty specifics, ILC defers to each individual site to make the necessary decisions related to color qualities, lumen output of the troffer, and specific warranty between that manufacturer and the site.
