Bancroft Library

Berkeley, California

Bancroft Library is a 5-story, 110,000 sqft special-collections library at UC Berkeley. This library is among the most heavily used libraries of its kind in the United States.

HVAC design for this project required the creation of unique archival conditions throughout the library. Stabilizing temperatures at 60 °F and 40% relative humidity was achieved through the use of desiccant dehumidification systems, as well as innovative dual-duct-reheat temperature and humidity control zones. Systems at Bancroft Library also include a water-cooled chiller plant.
