Portfolio: 700 6th Street

At the center of downtown Washington in the vibrant Penn Quarter, 700 Sixth Street is a classically-designed, modern office structure. 700 Sixth Street offers environmentally sensitive, energy-efficient and technologically advanced features and is designed to achieve the LEED Platinum rating by the USGBC.

This high rating was realized by incorporating sustainable strategies into the design, such as the green roof and 82 KW grid connected photovoltaic system. While the PV system supplies a portion of the buildings energy needs, the green roof increases energy efficiency, decreases stormwater runoff, reduces the heat island effect of the city, and adds roof top amenity space for the tenants. In addition, the 700 Sixth Street sets a benchmark for Washington as being the largest green roof on a private sector building and one of the first commercial buildings in DC to use a green roof as a Low Impact Development (LID) best management practice.
