ES & SEAS

Princeton University will build a new home for environmental studies and the School of Engineering and Applied Science on Ivy Lane across from Lewis Library, Payton Hall, and Princeton Stadium. (In this instance, "environmental studies" refers to the departments of GeosciencesEcology and Evolutionary Biology, and the High Meadows Environmental Institute.) The four buildings (all connected underground in one continuous sequence) will create a new ES & SEAS neighborhood that is carefully integrated into the surrounding context. It will maintain distinct identities for ES and SEAS and provide strong connections to nature and outdoor spaces. The project will advance the sustainability ethos of the University and reflect the importance of environmental studies and engineering in a 21st-century liberal arts university.

We design buildings and manage construction projects that help the University achieve our Sustainability Plan goals. See how on our sustainable design pages. The University is seeking LEED certification, a standard established by the U.S. Green Building Council, for the buildings.

If you have a question or concern about campus construction, please call us at 609-258-8023 (7:30 am – 5 pm) or submit a "Contact Us" form.

The ES & Commons celebrated a major milestone as the last piece of structural steel and timber were lowered into place on October 26, 2023. Project stakeholders were on site to sign the beam and cheer on its placement.
