Baumann Consulting DC Headquarters

Baumann Consulting

Washington, DC

LEED Platinum®


Located at 1424 K Street, NW, GBR Architects designed a new DC Headquarters for Baumann Consulting Engineers.  Embodying a strong commitment to sustainable design, the project achieved platinum certification under LEED for Commercial Interiors.


As a National Register Historic Building, built in 1905, only minimal changes to the existing mechanical system were allowed to the design team.  Consequently, all other systems needed to be designed to be as sustainable as possible to achieve the LEED Platinum level.  This includes lighting, plumbing and all interior finishes.


The 5,400 sf interior renovation included two large open floor plan work areas, a large glass fronted conference room, three meeting rooms along with a work room and pantry/dining area.  The two existing toilet rooms were renovated with ultra-low flush toilets and a third, accessible toilet room with shower was added.  We reused resin panels from the previous build out to create a bike storage area, with a sliding barn door, and reused glazing for the fronts of two meeting rooms and the conference room.  A Lutron lighting control system adjusts the new LED fixtures as the daylighting changes throughout the day.
