Originally built in 1922, the Federal Reserve Bank restoration and addition project entailed renovation of the existing 820,000 sq. ft. and 165,000 sq. ft. 14-story addition, which filled in an open section on the northwest corner of the building. Receiving an award from the American Institute of Architects, the renovation involved a significant change to the main lobby. The staircase that was a focal point of the original building was removed to open up a four-story space in the lobby. The Bank also reorganized all of the workspace in the building.

Indoor air quality monitoring takes on a larger role in work spaces such as these. The employees deal with the public regularly and all of the potential contaminants that other employees may also bring in with them. The Airflow Measurement Systems that were installed in this space are dedicated to monitoring the airflow rate to ensure the employees stay productive and happy, and to safeguard the employees and clients from potential airborne contaminants.
