• A highly reflective, ENERGY STAR qualified roof reduces the amount of solar heat absorbed by the building, decreasing the building's cooling load while minimizing the heat island effect.
• Additional commissioning and above-standard building mechanical system controls and monitoring capabilities optimize mechanical system performance and minimize energy use at the building.
• Water-efficient urinals, dual-flush toilets, and low-flow faucets with electronic shutoff, along with native landscaping and drought-resistant plants, reduce water use.
• Sand filters treat stormwater runoff for each tower to reduce total suspended solids entering the Potomac River by more than 80 percent and total phosphorous by 40 percent.
• A 1,711-square-foot green roof was installed on the area of roof that connects Potomac Yard One and Two.
• Thirty-five percent recycled content (approximately 670,000 pounds of ground granulated blast-furnace slag) was used in portions of the below grade, poured-in-place concrete structure.
• Indoor air quality is protected by the use of low volatile organic compound interior adhesives, paints, sealants, caulks, environmentally preferable janitorial and cleaning products, and integrated pest management practices.
