Princeton University will undergo one of the most extensive building programs in its history over the next decade — adding some 3 million square feet in new construction to house more students, expand research facilities, and replace aging buildings and infrastructure. Construction on this scale could pose enormous sustainability challenges. Princeton, however, is embracing it as a once-in-a-generation opportunity to lay the foundation needed to achieve “net-zero” greenhouse gas emissions before mid-century.
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.
Princeton’s greenhouse gas (GHG) reduction strategy is beginning to focus on transforming the University’s energy usage through Geo-exchange technology that transfers heat between the steady temperature of the earth and a building to maintain the building space conditions. This technology is one of the most promising developments in district energy. It is several times more efficient than an already-efficient cogeneration plant. By using geo-exchange instead of traditional fossil fuel combustion, Princeton hopes to achieve net-zero operation for heating and cooling the Campus in time to celebrate its tricentennial in 2046.

As part of Princeton University's goal to achieve climate neutrality by 2046, we are advancing our use of geo-exchange technology. Investing in geo-exchange projects, with enough capacity to serve the entire campus, will enable Princeton to phase out nonrenewable energy sources, including natural gas burned today to produce steam heat. Check out our new What is Geo-Exchange? flyer to understand how geo-exchange works, how we are not installing geothermal wells, and how our infrastructure projects work together to advance geo-exchange technology across campus.

Here in Facilities, we've been helping out during move-in for oh, a few years. We've assembled a list of tips and tricks that we hope will make your move-in experience a bit easier (check out tips 8 and 9 to help adjust your bed). Whether you are a new or returning student, welcome to campus! Our Facilities Customer Service team is here all year and happy to help.

Most heating systems on Princeton University's campus need to be turned on manually. Building heat is scheduled to be turned on around October 15, 2020, depending on the weather. We literally go building by building turning on individual heating systems in the fall, a very time-consuming process with the wide variety of heating systems in our wonderfully old and new campus buildings.

We can baaa-rely contain our excitement! Shearly Tilghman, our first lamb born at the University's solar field, now has lambs of her own. Shearly T and her two girls, born on August 17, 2020, are all healthy and doing well. Shepherd Julie cares for our solar field sheep in her barn when they are not at the solar field grazing and naturally keeping the grass low.

No, we're not trying to pull the wool over your eyes - say hello to the newest maintenance system at the Solar field. Ewe might think that this tight-knit crew just gets along on a few blades of grass, but we assure you they have the shear determination to get the job done.

A riddle: Which local entity finds 12,000 people working daily in its buildings and roaming its walks and roads? Which entity generates power from a fighter jet engine, has installed a large solar array, and calculates a self-imposed a carbon tax?

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.

Two “micro-steam” power-generating systems under Dillon Gym produce enough electricity to power several dorms. These self-contained power systems replace pressure reduction valves, capturing energy that would go unused.
