ZGF designed the 30,013 SF, two-story Car Barn Training Center (CBTC) to house District Department of Transportation (DDOT) operations, to provide a maintenance facility for the city’s streetcar fleet, and to establish a center for workforce training where students and residents can learn the technical skills for new transit jobs. The facility includes a control center, three maintenance bays and a wash track, administrative office and support space, a staff lounge and locker rooms, as well as two flexible training rooms that double as community meeting space. A terrace and green roof, shaded by an array of photovoltaic panels, is accessible from the mezzanine level and offers views spanning from the H Street Corridor to the Anacostia River and beyond. CBTC’s architectural and urban design achieves compatibility with its historic context—an educational campus built for African American students during segregation—through a contemporary application of compatible orientation, massing, and materials. On the interior, a light palette, large windows, and north-facing sawtooth skylights allow daylight to flood the facility and fill interior spaces, creating a bright and pleasant workspace. Designed to exceed LEED Silver®, CBTC incorporates sustainable strategies including grass tracks, permeable pavements, stormwater collection, native plantings, sunshading, and daylighting.
