Capitol Crossing is the culmination of decades of planning by community leaders, city planners, the District government, and District residents—and is one the largest private developments currently underway in Washington, DC. Capitol Crossing creates land in the heart of the District reconnecting two vibrant neighborhoods and is the first beyond LEED-Platinum projects in the metropolitan region. Capitol Crossing will create 5 new mixed-use buildings on a 7-acre site.

The tour takes participants around the site and into one building spotlighting all of new ways Capitol Crossing is an example of how to address common environmental concerns in urban developments. The project is a progressive, sustainable environmental design solution that employs innovative construction techniques, and resource-saving tools such as water cisterns, which will capture and treat over 90 percent of the storm water runoff as well as continuously capture ground water. Water harvesting will reduce potable water use by up to 40 percent.

Innovative energy-saving systems include an on-site cogeneration power plant providing tenants with stable electrical energy costs. The project includes expansive green rooftop areas to reduce heat island impacts and thus lowering the need for cooling during the warmer months of the year, in addition to expansive rain and underground water reclamation and reuse.

The project will even employ the use of innovative eco-chimneys—a living plant filtration system—to filter air from the parking garage. Glass enclosed greenhouses will filter the garage exhaust before it is released back into the atmosphere. The plant material will capture over 90 percent of the particulates from the garage air exhaust.
