U.S. Department of Energy Publishes GATEWAY report on Exterior LED Lighting at Princeton University
According to the Energy.gov website, “Evaluated on a lifecycle cost basis, SSL [solid-state lighting or LED] products can be competitive in parking lot applications because of their energy savings, directionality, controllability, aesthetic appeal, and maintenance savings.” Recently, the DOE released a case study highlighting exterior LED lighting at Princeton University. Since 2008, the university has welcomed innovative LED technology as part of their ongoing commitment to reduce greenhouse gas emissions while realizing energy savings. “Early in 2014, 41 new LED luminaires were installed in two Princeton parking lots as part of a major renovation to those areas. Because this was a new installation, the LED luminaires did not replace existing HPS luminaires, but saved more than 60% of the energy that would have been used by a conventional HPS system, with additional savings achieved through the use of controls.” Read the full GATEWAY report here.
KWReduction recently completed an LED parking lot lighting retrofit for StoneRidge Towne Center in Myerstown, Lebanon County, Pennsylvania. Here are the dramatic results:
