Located along the banks of the Anacostia River, the District of Columbia Water and Sewer Authority’s headquarters is a six-story, 150,000-square-foot building with a serpentine footprint that evokes the fluidity of water. A dramatic curved, curtainwall façade appears to flow around the landscape.

The curtainwall creates the form with a series of planar modules installed at varying degrees to simulate a curvilinear path. As each floor ebbs and flows, the facade blends from offset independent strips of framing to a unified wall of glass and metal panels. Solar shading panels at the southeastern and southwestern faces are integrated into the curtainwall.

To complete the LEED Platinumcertified project, Icon Exterior Building Solutions LP installed 55,000 square feet of Erie Architectural Products Inc.’s ENVIRO|FACADES unitized curtainwall. Exterior aluminum framing has a twocoat Kynar paint finish. Interior finishes are one-coat acrylic paint.
