Description

From May to July 2006, EPA employees that had been working in three separate buildings in the Crystal City area of Arlington, Virginia, moved into a newly constructed building nearby that incorporates a number of sustainable features. In May 2004, the U.S. General Services Administration (GSA) signed 10-year leases for 405,117 rentable square feet of space in two interconnected towers known as Potomac Yard (EPA occupies the South Tower and a portion of the North Tower).

In 2006, the building received the U.S. Green Building Council's Leadership in Energy and Environmental Design (LEED^®)Gold-level certification for new construction. View the Potomac Yard One LEED Scorecard (PDF) (1 pg, 40K) and the Potomac Yard Two LEED Scorecard (PDF) (1 pg, 41K).

In addition to the Potomac Yard facilities, EPA Headquarters occupies space in several other buildings in the Washington, DC metropolitan area, including:

Awards

On November 15, 2007, building architect Davis Carter Scott received the 2007 Northern Virginia Chapter of the National Association of Industrial and Office Properties (NAIOP) Award of Excellence: Best Building High Rise, Eight Stories and Above for Potomac Yard One and Two.
In November 2007, DOE presented the Potomac Yard facility with a Federal Energy Saver Showcase Award, which honors facilities that use cost-effective energy efficiency, water conservation, and renewable energy technologies.
In May 2007, EPA's Potomac Yard facility won a 2007 White House Closing the Circle Award for its sustainable design and energy- and water-saving features.
Potomac Yard One and Two were finalists in the commercial design category of Environmental Design + Construction magazine's Excellence in Design Awards.
In January 2007, Davis Carter Scott received a Best Building, Environmentally Responsible – Green Construction: Award of Merit from NAIOP for the company's work on the facilities' design. The award honors the architect's ability to convert the original designs for Potomac Yard One and Two from conventional buildings to LEED-certified facilities. Read more about the award in the Davis Carter Scott press release (PDF) (2 pp, 68K).

Environmental Features

The solicitation for offers (SFO) for Potomac Yard included environmental provisions developed by EPA to ensure that the facility promotes energy and water efficiency and environmentally preferable materials and design. The new space strived to meet these goals and in doing so achieved the U.S. Green Building Council's LEED^® Gold 2.1 certification for new construction and the ENERGY STAR^® building label.

Energy Conservation

In August 2007, Potomac Yard One earned the ENERGY STAR building label. The lease required that the building meet ENERGY STAR building energy performance standards. Only non-chloroflourocarbon based refrigerants were used. Additional commissioning and above-standard building mechanical system controls and monitoring capabilities optimize mechanical system performance and minimize energy use at the building.
A highly reflective ENERGY STAR roof reduces the amount of solar heat absorbed by the building, decreasing the building's cooling load, while minimizing the heat island effect of the building.

Green Power

On December 20, 2005, EPA signed a three-year green power contract (procured through the Defense Energy Support Center ) for its Potomac Yard offices. Annual delivery of 4.2 million kilowatt hours (kWh) in the form of renewable energy certificates (RECs) began on February 1, 2006. This purchase, which offsets 100 percent of the facility's annual electricity consumption, supports the generation of renewable energy at wind farms in Minnesota, Nebraska, Oklahoma, and Wyoming.

Water Conservation

The 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 the North and South Towers.

Stormwater Management

Sand filters treat stormwater runoff for each tower, and should reduce total suspended solids by more than 80 percent and total phosphorous by 40 percent from entering the Potomac River.

Waste Reduction and Recycling

The building was designed and built to be consistent with EPA's revamped Headquarters recycling program.
The developer recycled 71 percent of the construction period waste, diverting 2,000 tons from landfills.

Alternative Transportation

Extensive bike parking and shower facilities are available for employees that bike to work. The building is located near the George Washington Parkway and Four Mile Run bike paths used by bike commuters.
The building is in close proximity to the local Metrorail trains, Metro buses, and the Agency shuttle bus routes. Shower facilities and onsite bicycle parking for 53 bikes are provided to encourage environmentally responsible commuting.
In FY 2005, 84 percent of Headquarters' new fleet acquisitions were alternative fuel vehicles (AFVs). Since 2000, EPA has exceeded the requirements of Executive Order 13149, which calls for at least 75 percent of new vehicle acquisitions to be AFVs.

Other Features

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.
