2RW contributed to the study and conducted a photovoltaic feasibility analysis before providing sustainable MEP/FP engineering for the addition and renovation. The design features high-bay mobile shelving to maximize storage capacity, housing over 2.5 million printed volumes, artwork, newspapers, and various electronic and film-based media—requiring approximately 825,000 cubic feet of high-density storage. Portions of the existing administration and patron areas were reconfigured to support new and relocated program functions. The project prioritized operational efficiency, leveraging existing shared spaces, and ensuring a strategically accessible location with room for future growth. Key design objectives also included enhancing accessibility and ensuring ease of maintenance.

HVAC systems were designed to maintain stable archival conditions, holding temperatures at 60°F (15.6°C) year-round with relative humidity ranging from 42% in winter to 52% in summer. These conditions are chosen to provide a stable and controlled environment for the proper conservation of historical and sensitive documents. Energy-efficient LED lighting system was designed to meet the challenge to reduce the lighting power density due to the high ceiling height and high footcandle requirement. Occupancy sensors reduce unnecessary energy consumption by illuminating only active shelving rows. To mitigate cost, the power for the new addition was provided from the existing switchboard which had the capacity to serve it. The energy efficient systems contribute to the project’s LEED Silver certification goals.
