Now Duffy is making a much bigger promise: If Cornell and Technion follow through with SOM’s winning plan, the 400,000-square-foot first phase of the tech campus will also create as much energy as it uses. A solar array that will generate 1.8 megawatts at daily peak and a four-acre “deep earth” geothermal well field will provide heating and cooling and will also recharge fuel cells. According to Duffy, who tends to speak grandly—but in this reporter’s experience, delivers what he promises—the need to produce, and conserve, energy will affect every aspect of the design, with strictly formal considerations giving way to what he calls “a new aesethetic” of sustainability.

Renderings released by SOM show eight silver-colored buildings arranged in a zigzag pattern on the south end of the island where a complex of hospital facilities currently stands. SOM’s buildings, which are meant to foster “impromptu meetings that lead to innovation,” Duffy says, will have large interior courtyards and will be linked by above-ground walkways. The firm’s history with such walkways has not been entirely positive. Back in the mid-1960s Walter Netsch of SOM's Chicago office designed the new campus for the University of Illinois Chicago Circle, which was hailed in part for its extensive system of elevated pedestrian walkways. Thirty years later, the walkways, widely seen as a disaster, were torn down.

Duffy knows that history but says his walkways will be totally different from what he called “Netsch’s rabbit warren.” Colin Koop, who headed the project team under Duffy, says they will be generous public spaces, positioned to become main circulation routes, and programmed with cafes and other amenities to keep them populated. The outdoor walkways, and surrounding park, which were designed in collaboration with James Corner Field Operations, are expected to be open to the public.

When the competition was under way this fall, the SOM/Corner team presented its design to representatives of the Economic Development Corporation and then of the City Planning Commission. So did architects for Cornell/Technion’s competitors, including Ennead, on behalf of Stanford University (which later dropped out of the competition). Still, it’s hard to know how much of a factor architecture was in the city’s choice of Cornell/Technion, given the Bloomberg Administration’s extensive focus on finances. And it isn’t yet known if SOM will design the project and its component buildings (intended to total 2 million square feet by 2043). Though there has been speculation that the university could snub SOM and select a firm with ties to its own architecture school, Cornell would risk delays—as well as blows to its reputation—if it abandoned the architects that helped it win the competition. So far, SOM has begun the land use review stage of the plan, but future phases are still up in the air.

What is clear is that this is a big opportunity for Roosevelt Island. Long home to an asylum and then a smallpox hospital, it was known as Welfare Island until 1973, when the name was changed to attract residents to new apartment buildings (built in accordance with a 1969 master plan by Philip Johnson and John Burgee). In 1989, a subway station opened on the island, dramatically improving access. Now, a monument to Franklin D. Roosevelt, designed by Louis Kahn in the 1970s, is being realized by Mitchell/Giurgola Architects on the island’s southern tip. According to Duffy, the campus he envisions will not overwhelm, but will provide a “great prelude,” to Kahn’s memorial.
