A college campus features a wide range of lighting applications under one administrative “rooftop” – classrooms, offices, theaters, labs, libraries, dining halls, dormitories, museums, chapels, walkways, parking lots, parking garages, lecture halls, arenas, and outdoor stadiums. Campuses are ideal testing grounds in which to study lighting in its many forms, and they provide unique opportunities for broad implementation of energy efficient technologies that prove their value in initial applications.


In 2008, Princeton University, in Princeton, NJ, developed a sustainability plan to reduce campus greenhouse gas emissions to 1990 levels by the year 2020. LED lighting was viewed as a key component to this long-term goal. Conversions to LED began with a pedestrian walkway and then progressed to parking lots and a parking garage before moving indoors to a variety of environments, including offices, the Carl Icahn Laboratory, and Dillon Gymnasium. Princeton is working with the GATEWAY Demonstration Program on a number of these LED conversion projects.
