Tuck Sustains launches the GreenLite system in Tuck residence halls Thanks to a gift from the Class of 2010, Tuck Sustains launched the GreenLite system in Whittemore, Achtmeyer, and Pineau-Valencienne residence halls. GreenLite, an energy and sustainability information system where a cartoon polar bear serves as a visual indicator of energy use, was created by Lorie Loeb of the Computer Science Department and a team of undergraduate students. A competition to reduce energy use will be held this spring among the Tuck students living on campus.
