In a small room tucked in a corner of Princeton University, Princeton, NJ's MacMillan Building, computer screens cover the wall and line desktops, each displaying a colorful cornucopia of data used to monitor campus energy equipment and limit the University's energy consumption.

Without leaving their seats, Facilities staff can use the computers to remotely turn off air conditioning in vacant classrooms across campus or inspect one of the hundreds of fume hoods in Frick Chemistry Laboratory to ensure it is ventilating properly.

The University's Energy Management Center in MacMillan is at the hub of aggressive efforts to limit energy usage and costs in buildings across campus, supporting Princeton's comprehensive Sustainability Plan to reduce carbon dioxide emissions to 1990 levels by 2020.
