What is the Interior Lighting Campaign?

2019 ILC Recognition for Exemplary Peformance
Learn More....

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 campaign focus is on troffer, high-bay, low-bay, and suspended linear lighting systems and lighting controls.

As of December 2018, ILC Participants have logged the planned or completed upgrade or new installation of more than 3.5 million high efficiency lighting and control systems.  These installations are expected to save over $84 million annually in electricity costs through energy use savings of nearly 800 million kWh.

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 possibly 80% with the use of controls.

2019 ILC Goal
                                             ILC Goals Progression Towards 3.5 Million Luminaires

  • Access to resources, including specifications, case studies, utility incentive lists, and educational webinars to help building owners make sound lighting decisions.
  • 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?

  • 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, high-bay, low-bay, and suspended linear 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.

Equipment Requirements

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 and troffers, high-bay, low-bay, and suspended luminaires that meet the DesignLights Consortium (DLC) Technical Requirements V4.2 should typically meet the 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.
