Rubenstein Commons, Institute for Advanced Study

The Rubenstein Commons at the Institute for Advanced Study (IAS) in Princeton, NJ, established in 1930, is a new commons building on the historic campus. It is sited near the Institute’s flagship 1939 building Fuld Hall where Albert Einstein spent his last thinking years.

The design for Rubenstein Commons is driven by the concept of intertwining. Exterior circulation weaves into and through the building. The building is conceived as a social condenser with a variety of flexible meeting spaces supporting community and academic life on the IAS campus. The new building follows the existing topography primarily in a single level program with gradual slopes and offers views of the courtyards.

The building forms an intertwining through the landscape, connecting with pools of water on the north, south, and west. The pools reflect sunlight into interior spaces, producing an atmosphere of reflection. Natural phenomena connect with science, physics, humanities, and art—corresponding to the Institute’s mission.

The geometry of the spaces is formed by “space curves” where two non-planar curves intersect. As former IAS Director Robbert Dijkgraaf remarks, the curved ceilings give space for “thought bubbles” of the scholars.

Blackboards of natural slate, a storied tradition for intellectual curiosity and exchange at the IAS, line the interiors. Prismatic glass breaks white light into the color spectrum, energizing the interiors with natural light and color. Custom hand-blown light fixtures illuminate the curved ceiling geometry. Door handles inspired by knot theory and custom waterspouts greet visitors at the east and west entries to the building.

The landscape around the pools measures the time of a year’s passing through the four seasons. Spring is marked on the east side with pink blooming redbuds emerging in clusters along branches of the grove. Summer is marked to the south with rich green leaves of ginkgo trees, accented by Russian Sage purple flowers. Fall is marked to the west with vibrant red maples and the golden gingko leaves provide a striking contrast around the south reflecting pool. The north gardens are framed with a border of white pines and American hollies providing a green backdrop in the winter but also year-round.

The façade of the Rubenstein Commons pays tribute to Albert Einstein’s work through innovative use of light. Featuring wide-spanning steel post-and-beam structures with slim T-profiles and frameless, curved skylights, the design emphasizes openness and luminosity. A key feature is the use of 19 mm thick prismatic glass, ground into geometric forms and chemically tempered for strength, which refracts light to create dynamic spectral effects—turning the building itself into a poetic expression of Einstein’s theories.

20 geothermal wells powered by the cycle of the earth’s seasonal temperature heat and cool the building with radiant floors. Natural ventilation in wood framed windows bring light and air into all spaces.
