Professionals of Viridian assisted the Tishman Speyer management, Norman Foster Architects, Flack + Kurtz MEP to create an energy-efficient, environmentally considered building. A range of envelope, lighting, HVAC and control strategies were studied during the core and shell design. Investigations were also made into enhancements to the subsequent fit-out. The work was co-funded by the New York State Energy Research & Development Authority and was performed by the Energy/Green/Commissioning group of a different company. This group formed Viridian's nucleus in 2006.
