As the former home of the U.S. Department of Transportation headquarters, the David Nassif Building has held a commanding presence at the intersection of 7th & D Streets, SW for nearly four decades. The building is being dramatically reinvented as Constitution Center, a completely renovated property offering cutting-edge technology and security standards that exceed ISC Level IV.
The Office of the Comptroller of the Currency (OCC) occupies 50% of the building’s first ten floors. OCC’s offices total nearly 640,000 ft² of renovated space that achieved Gold certification under LEED for Commercial Interiors (LEED-CI) version 3.0.
This innovative project includes the use of chilled beam technologies not commonly found in the Washington, DC area. Baumann Consulting was chosen to commission and verify performance of the chilled beam system based on their extensive experience and expertise in radiant cooling systems from numerous projects in Europe. Baumann Consulting also acted as the Commissioning Authority (CxA) and commissioned the remaining building systems including HVAC, electrical, fire alarm, and fire suppression.
