Behind the orange construction signs is a green mission.
Jadwin Hall, the building once reserved for some of Princeton University’s most expansive physics experiments, has received a full makeover to give it a more energy-efficient edge.
Started in 2009, the renovations are now 95 percent complete, according to project managers, and the changes are expected to help reduce the building’s energy usage by 45 percent once they are fully implemented by the end of the summer.
“The university tracks the energy use of all the buildings on campus,” project manager Cathy Altadonna said. “There are well over 100 buildings, and Jadwin was a visible blip on the radar when it came to energy use.”
