This 110,000-square-foot urban revitalization project achieved LEED Gold certification. The project contains many sustainable features including a central four-story atrium that provides daylight, interior landscaping, views from all work stations, and exposure of the rainwater harvesting system. Energy savings up to 40 percent were achieved through cooling capacity reductions, daylighting, and a thermal envelope including high-performance windows. An underfloor air distribution system provides individual thermal comfort with air diffusers providing 100 percent ventilation efficiency. Water consumption reductions of over 80 percent were achieved through a rainwater system that collects rainwater via piping to a 5,000-gallon cistern.

More than 34 percent of building materials are recycled, eight percent are salvaged, and over 75 percent were manufactured locally. The exterior consists of aluminum, insulated panels that clip to steel structural components. The building project incorporates the reuse of an abandoned historic building. Other green highlights include ENERGY STAR roofing materials and green roof areas, extensive commissioning procedures, construction waste management, and low-VOC paints, adhesives, and sealants throughout.

- Armstrong mineral fiber ceiling tiles and Armstrong Prelude grid system
