This is a case study for the Tinker Air Force Base. By replacing the existing lighting with LED fixtures, this project saved more than 60% energy compared to the existing technology. This is consistent with savings of converting either fluorescent or high-intensity discharge fixtures with either new LED fixtures or retrofit kits, which typically result in at least 45% savings. The lighting controls saved between 8-23% compared to the LED baseline. Because LEDs are very efficient, the new LED baseline uses less energy. As a result, the 20%+ savings does not result in sufficient savings for a reasonable payback. However, using lighting controls to control other building systems can make the lighting and control system more cost effective.

This presentation from Michael Myer, Lighting Researcher at Pacific Northwest National Laboratory, covers energy savings potential for lighting systems integrated with HVAC and plug loads, reviewing findings from several field project case studies conducted on behalf of the U.S. Department of Energy.

This presentation from Kandice Cohen, Director of Lighting Strategy at Trane Technologies, covers the reasons integrating lighting systems is beneficial, using a “Baker’s Dozen” commercial kitchen as a case study.  Kandice discusses the integration of the connected lighting control system with the building automation system and how it meets the customer’s needs.

The California Lighting Technology Center, in collaboration with the California Energy Commission, is conducting research to develop and evaluate technology that integrates automated controls for HVAC, electric lighting and dynamic fenestration systems.
