Engineering and Campus Energy builds and maintains the infrastructure on, and below, the Princeton University campus. We are responsible for the operations and maintenance of the central energy plant, the design and management of building system upgrades, and energy management. Using best practices in the design and execution of engineering projects, we support Princeton University's Sustainability plan by reducing energy use and environmental impacts. Our staff includes plant operators, mechanical and electrical engineers, as well as building control system operators and designers. No matter what, we aim to keep the lights on and the steam flowing.

For more detail on our department, feel free to explore our oganizational chart or find a team member in our staff directory.

    Princeton University is making campus lighting more sustainable and efficient one fixture at a time. Through the Lighting Efficiency Upgrade Program, the University will convert more than 100,000 fixtures to light-emitting diode (LED) technology in buildings across campus. The improvements will significantly reduce carbon emissions, promote cost savings and limit waste.

    Large energy users such as industrial facilities, hospitals, apartment complexes and universities seeking energy resiliency, stability in energy prices and the ability to operate independent of the grid are increasingly turning toward combined heat and power, or CHP, facilities to meet at least a portion of their energy needs.

  • Jun. 9, 2015

    The most advanced microgrids use multiple fuel sources, multiple power-generating assets, energy storage, CHP production, and modern digital controls. They operate with an awareness of the real-time commodity costs of fuel and electricity.

    The Princeton Energy Plant is a district energy facility that provides electricity, steam, and chilled water to power, heat, and cool the buildings on the Princeton University campus. The creation of the plant and the continuous refinement of its operation have had a very positive impact on Princeton's carbon footprint. Princeton's carbon emissions reduction goal, as stated in the Sustainability Plan, is to reduce emissions to 1990 levels by 2020.

    Reverse Osmosis Heat System

    The water that circulates through boilers is constantly being replenished with water from an outside source. The reverse osmosis conditioning system removes minerals and ions from the incoming water. It's one of the key systems that keeps up efficiency and keeps down maintenance costs.

    Another key component to Princeton's energy management program are building controls, specifically, replacing older pneumatic controls with direct-digital-control (DDC) technology. The University uses full direct digital control (DDC) in 125 buildings on Campus. All of the heaviest energy-use buildings are included. There are over 80,000 control points in the system.
