About 750 offices are integrated into 217,000 square feet (20159 m2). A 2-story central atrium has a skylight, so natural light can filter into the building, and localized light and temperature controls allow occupants to customize individual spaces to personal comfort levels. Bicycle storage is located near building entrances, and access to public transportation encourages employees to commute. About 88 percent of construction waste was recycled, diverting 1,450 tons (1315 metric tons) of material from landfills. About 20 percent of materials used included recycled content, and 28 percent of materials were manufactured within a 500-mile (805-km) radius. Carbon-dioxide sensors monitor CO2 levels and increase airflow when necessary.
