New York Public Library

Stephen A. Schwarzman Building (SASB)


The Stephen A. Schwarzman Building is a National Historic Landmark providing a great range of public programming within its walls including events and exhibits, as well as valuable research. Starting from a master plan, the design team evaluated the needs of the iconic building which, included improving infrastructure and the visitor experience. Underutilized spaces would be transformed for public use and research, while MEP/FP infrastructure serving multiple spaces would be prioritized and replaced.

The scope of work within The Stephen A. Schwarzman Building includes selective and phased renovations to increase public spaces and address aging MEP/FP and IT infrastructure and systems. Systems design and component selections must be strategic and take into consideration several project challenges. Maintenance of indoor environmental conditions for the library’s significant collections, varying occupancy patterns, enhanced thermal comfort, and priceless architectural interiors are all critical. Modifications to the central chilled water plant, replacement of air handling units, incorporating a new Building Management System (BMS), upgrades to IT and electrical services and distribution, and new core restrooms are just a few of the infrastructure measures being implemented to enhance the operation of the building systems. Given the strict environmental conditions in several of the spaces throughout the building, it is imperative that the new equipment be commissioned to ensure performance.

The Stephen A. Schwarzman Building is slated for completion in 2023.
