Prominently located near the Lincoln Memorial in Washington, D.C., the United States Institute of Peace contains offices, an international conference center, and public exhibition and event space. The wing-like roofs connect the building’s three curving sections, enclosing two atria below. These multi-layer translucent structures presented the most challenging lighting problem – to light the roofs with no visible sources so they glow softly both inside and outside. A pervasive lighting theme is present
throughout, revealing and animating but never competing with the architecture.
The translucent roofs are comprised of outer diffusing glass and an inner white membrane, with structure sandwiched in between. Extensive computer modeling, material sample testing and a full-scale mockup in Germany were required to determine the roofs’ transmissive and diffusing characteristics and to validate the lighting solution.

“The technical challenge of lighting the curved roof structure has been mastered seemingly effortlessly,” one judge praised of the final result. Perimeter offices are fully daylighted. Clerestories bring daylight into corridors so that they often do not need to be lit with supplemental electric light. Continuous T5 strips integrated into the curving clerestories’ base provide dual function – indirectly lighting both offices and corridors – keeping the ceiling surfaces pristine.
