The JBG Companies developed this new facility as a build-to-suit office for the National Institute of Allergy and Infectious Diseases (NIAID). The building accommodates approximately 2,100 staff in a mix of open plan workstations and enclosed private offices that feature demountable partitions. This design approach maximizes flexibility for NIAID as their staffing needs change over the life of the 15-year lease.
The mechanical and electrical systems were also designed in a modular concept to support the adaptable nature of the architecture. Lighting controls are digital and wireless to further support the flexibility of the space by allowing lighting to be reassigned to different switching devices as spaces are modified.
General office spaces are conditioned by shut-off variable air volume (VAV) boxes served by floor by floor chilled water air-handling units (AHU). The design and placement of VAV boxes was done so that all possible configurations of the modular office concept could be accommodated with minimal changes to the original construction. All specialty spaces are conditioned by supplemental systems tied into an additional dedicated chilled or condenser water loop that was designed as part of the base building’s central plant design.
The project achieved a certification level of Gold under the LEED for Core & Shell™ rating system. GHT also provided LEED commissioning services for the base building and mechanical, electrical, and plumbing (MEP) engineering design for the interior-fit out.
