Arlington Virginia Green Building Program Arlington is going "green!" From community centers to private office buildings, and from new purchasing practices to long-standing community planning, Arlington County has made the commitment to being a steward of its environment. Arlington County's first certified green building opened in September, 2003 (Langston-Brown School and Community Center), and several projects in planning that are registered with the United States Green Buildings Council's Leadership in Energy and Environmental Design (LEED) program. Each project is being targeted to qualify as a silver-rated LEED-certified building upon completion.
