An Award-Winning DC Renovation

Human Rights Campaign Headquarters Renovation
Washington, DC, USA

The Washington Business Journal named this the “Best Urban Project” and the NAIOP honored it as “Best Renovation or Adaptive Reuse.”

The Human Rights Campaign headquarters building is a renovation of an existing eight-story building constructed in 1956, with an addition in 1974.

The design team approached the renovation of the exterior building envelope as a re-sheathing of the building’s classic mid-century modern form with contemporary materials and technology in a way that both respected and refreshed the original design.

Sustainability was a major component of the renovation, which included new MEP systems, restrooms and a partial new roof.

The previous single-pane, uninsulated windows and curtain wall were replaced with new, high-performance glass and aluminum window wall systems. The amount of glazing was increased, allowing for floor-to-ceiling windows on the main facades. Combined with a narrow floor plate that incorporates extensive interior glazing, daylight enters most of the occupied spaces. Perimeter HVAC units were replaced with a central rooftop unit that has an evaporatively cooled condenser with an energy management system.
