The former Bell Labs building—which previous-  
ly hosted 44 years’ worth of research and develop-  
ment—was taken over by Somerset Development  
New Jersey and is undergoing a more than $100  
million adaptive reuse redevelopment.  
During the initial testing, a full-size mock-up  
consisting of 64 lites of glass was installed at the  
atrium to ensure it would work with the existing  
framing system—while at the same time offering  
the aesthetics and transparency desired.

Glass Used  
The overall project consists of 3,200 panels of  
amorphous silicon photovoltaic glass by Onyx.  
Structural engineer LaufsED surveyed the exist-  
ing skylight and determined a total of 24 different  
types of photovoltaic glass would be required to  
cover all the different existing glass schemes.  
The ongoing large-scale retrofit includes the  
integration of electricity-generating photovoltaic  
glass from Onyx Solar into the building’s existing

Progress Report  
Solaria Corp. recent-  
ly supplied 2,300 of its  
PowerXT and customized  
PowerView solar modules to buildings on Cornell Tech’s new campus on  
Roosevelt Island in New York City.  
The campus’ Bloomberg Center, designed by mOrphosis Architects,  
and Bridge building, designed by Weiss/Manfredi Architecture/Urbanism/  
Landscape, combine for 47,000 square feet of Solaria photovoltaic panels, the  
equivalent of a 900-kilowat system.  
As of August, the most prominent area of the  
skylight—the center—was completed, and the work  
was being completed on the East and West sections.  
According to Onyx, a logistics plan was put in  
place allowing for partial deliveries of the glass in  
order to reduce storage needs. All of the photovol-  
taic glass will be delivered within a 17-week span.
