Originally built in 1966 at the heart of Arizona State Universitie's campus, Hayden Library sees nearly 2 million annual visitors. The library modernization added 30,000SF of the usabel space, including a Makerspace, collaborative student spaces, new reading rooms, a highly flexible media studio, a variety of research services and interdisciplinary learning labs, as well as a substantial area dedicated to featuring works by prominent Arizona Artists.

MCH provided full acoustical consulting services, involving sound isolation, HVAC noise control, and interior finish recommendations. Partitions and room dividers needed to provide openness and access while also maintaining appropriate isolation and acoustic separation. The chilled beams that replaced the old VAV HVAC system to enhance energy efficiency required special acoustical attention to insure speech privacy and quiet environment. Many interior finishes are integral to the blended composition of the various partitions and ceilings.

The Hayden Library has received numerous design accolades upon opening, including the AIA COTE top ten award, and listed in Architecture News best of design awards for 2020. In 2021, it achieved LEED Platinum certification.
