The building has an efficient heat pump system with heating coil bypass for winter operation. A gas-fired microturbine and photovoltaics contribute to the energy efficiency. Good indoor air quality is provided by low-emission finishes and mechanically-filtered, air-conditioned, winter-humidified air. Other sustainable design elements include a black water treatment plant, storm water reuse for irrigation and green roof.

The energy and green analyses were performed by the Energy/Green/Commissioning group of another company. This group formed Viridian's nucleus in 2006. The design team included Robert Stern Architects, lsmael Leyva Architects, Cosentini Associates MEP. The work was co-funded by the New York State Energy Research & Development Authority.
