Indiana University Lilly Library
Founded in 1960, The IU Lilly Library is an important rare book and manuscript library located on the Indiana University Campus. The building underwent a complete interior renovation including the addition of a new elevator, office spaces, and exhibition areas. The building’s mechanical and electrical systems were original to the building and were part of a complete upgrade to a new, highly efficient system. Plant chilled water and steam are used for a VAV system that maintains very strict temperature and humidity tolerances continuously throughout the year. Due to the extensive rare book collection, the building is designed to operate between 68-72 degrees with a 45-50 relative humidity year-round. Extensive controls, chilled water, hot water, clean steam and energy wheels were all utilized to maintain such tight tolerances. The lighting system was updated with dimmable LED fixtures and digital controls complete with occupancy sensors for increased energy savings. Emergency power was added to the building from an existing campus generator to support life safety functions of the building. Various rooms were converted to seminar spaces complete with new audio-visual systems to provide both informational and instructional services the user. Access control and video surveillance systems were added and the existing intrusion detection system was upgraded to increase the security of the building collections.
