- Potomac Yard One received the U.S. Green Building Council’s LEED® Gold for New Construction (version 2.1) level certification in June 2006.
- Potomac Yard One received LEED Gold for Existing Buildings (version 2.0) certification in July 2008 and received LEED Platinum for Existing Buildings (version 2009) certification in January 2014.
- Potomac Yard One has earned the ENERGY STAR® annually since 2007, most recently in 2018 with a score of 93.
- 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, native landscaping and drought-resistant plants reduce water use.
- Sand filters treat stormwater runoff 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.
- 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.
