Team members at Sustainable Investment Group (SIG) helped the buildings at 1940 and 2000 Duke Street in Alexandria, VA earn LEED Silver certifications.

Overview:
Perched at the edge of Alexandria’s vibrant and prestigious Old Town district, 1940 and 2000 Duke Street are low-rise commercial buildings often referred to as the Crescent at Carlyle. Together, they form the entrance to the master-planned mixed-use development anchored by the extensive U.S. Patent and Trademark Office complex. At 70.52 feet tall, 1940 Duke Street’s six stories and 216,577 square feet are home to a variety of enterprises, including a leading patent and trademark law firm, global Internet providers, scientific and engineering firms, professional associations and training companies, many serving the federal government and defense industries. Slightly smaller at 58.77 feet tall and 170,687 square feet of space, 2000 Duke Street’s occupants include some of the U.S. Patent and Trademark Office facilities and a nationally known investment education company.

Implementing a variety of efficiency initiatives, Sustainable Investment Group (SIG) recently helped both properties achieve ENERGY STAR and LEED® Silver certification. Built in 2003, 1940 Duke Street has earned ENERGY STAR status five times, most recently achieving a score of 91 that is well above the average rating for Virginia ENERGY STAR businesses. 2000 Duke Street was built in 1997, gaining ENERGY STAR recognition four times since 2011 and holding a Green score from the OMG Scorecard on Sustainability and Energy.

Both commercial properties are Class A buildings with a variety of amenities and restaurants to serve tenants, their employees and their clients. 1940 and 2000 Duke Street also offer underground parking facilities and a convenient location next to the King Street Metro Station. More than 25 restaurants, eight hotels and several shops are within a half-mile radius of the Crescent at Carlyle, and the Amtrak station is just a six-minute walk away.
