Princeton Energy Efficiency Fund

Princeton University established a revolving energy efficiency fund in 2012 to support ongoing campus energy efficiency upgrades. As part of a larger, $45 million energy master plan, Princeton University is committed to reinvesting $5 million of the energy savings back into energy efficiency initiatives. In complement to Princeton’s long legacy of investing in energy efficiency innovations, a dedicated energy manager was hired in 2008 to develop and implement a campus energy master plan. The energy manager is responsible for developing and delivering capital energy projects, control system optimization platforms and metering dashboards that will contribute to the university achieving its 2020 greenhouse gas and energy conservation goals. These efforts include auditing the top 50 most energy intensive buildings on the campus with the goal of identifying and implementing retrofit opportunities that are both environmentally and economically defensible. The energy master plan is expected to reduce the annual energy budget by one third and achieve $8.5 million in annual savings.
