As part of the Campus Wide Lighting Efficiency Upgrade Program designed to reduce carbon emissions, promote cost savings and limit waste, Princeton University’s Facilities Organization decided to convert more than 100,000 outdated lighting fixtures to more efficient LEDs across campus. One of the largest and most visible initiatives in the program was the conversion of 839 lighting fixtures that illuminated the main floor of the 250,000-square-foot, world-class Jadwin Gym.
After several years of research through multiple manufacturer samples, the university and its partners chose Hubbell Industrial Lighting LED Lunabay Series Highbays, which are designed for light-retail, gym and light-industrial spaces. The LED Highbays provide Princeton University with long-lasting, efficient lighting and enable appropriate light levels, uniformity and CRI required for televised broadcasts of games. The lighting has a life of 50,000 hours, reducing facility staff time spent on aerial lifts to replace thousands of burnt-out metal-halide lamps and failed ballasts.
Hubbell Building Automation’s wiSCAPE allows facility managers to illuminate the entire space for large events or reduce lighting levels with precision, down to a specific row in the spectator bleachers.

The Retrofit
Jadwin Gym is not only home to the NCAA-level basketball court and indoor track, but it also hosts speakers, such as the Dalai Lama, former U.S. Secretary of State Condoleezza Rice and Eddie Murphy. It serves as a location for the annual university prom, concerts and large-forum dinner events, too.
Television broadcasts, sustainability needs, a uniquely domed roof and a restricted installation schedule made the lighting retrofit challenging.
Along with the lighting manufacturer, university officials and their designers and specifiers developed a solution that enhanced the environment, met key energy-saving criteria and achieved necessary standards for television while playing to the strengths of the facility without detracting from its uniqueness.
By replacing the existing high-bay fixtures, Princeton’s energy-management team estimates energy savings of approximately 40 percent. Controls optimization should add an additional 20 to 40 percent energy savings. It is estimated the total return on investment in the Jadwin Gym lighting upgrade will be less than six years.
The experience from start to finish results in a win for Jadwin Gym,” says Aramark/Princeton University Senior Project Manager Brian Robertson. “Whether it was meeting the demands for fixture aesthetics or complex controls options, Hubbell Lighting easily understood the mission of the Jadwin Gym lighting upgrade program and was able to accommodate our needs and provide a quality, custom product that is modern, reliable, architecturally compliant, efficient and environmentally responsible. They were also able to meet our critical installation schedule by ramping up factory production to get fixtures delivered onsite prior to the 2015-16 basketball season. The new lighting system exceeds the expectations of the Athletics department. The players, coaches and staff have commented on the improvement and how excited they are to play under the new lights. Hubbell Lighting was a true partner in this process and we look forward to playing under their lights this season and many seasons to come.”
