One and Two Potomac Yard represent one of the first green, new speculative office building projects in the Washington, DC area. The project is located on a formerly abandoned railroad yard in Arlington, Virginia.

The Potomac Yard building saves water through the use of plumbing fixtures such as low-flow urinals, dual-flush toilets, and low-flow faucets with electronic shutoff. Landscaping includes drought-resistant regional plants that do not require extra watering, and, as a result, no irrigation system is needed. A small green roof was installed on the area of roof that connects Potomac Yard One and Two. In 2006, the buildings received the U.S. Green Building Council's (USGBC's) version 2.1 Leadership in Energy and Environmental Design (LEED?)Gold-level certification for new construction (NC).
