The new music and communication building is located south of Northwestern University's Pick-Staiger Concert Hall and Regenstein Hall of Music, on the southeastern edge of the Evanston campus. Sitting on a prime site fronting Lake Michigan and a new arts green, the building serves as a signature facility. Designed to wrap and connect with Regenstein Hall, the building enables the School of Music to consolidate its programs for the first time ever. The dynamic, Z-shaped plan of the building mass defines the eastern edge of the arts green then jogs to the western edge of the lake. A large atrium divides this form, providing the main entry and gathering space and offering clear views of the lake. Certified LEED Gold, the building offers a variety of innovative sustainable features, including a double-skin facade and grey-water system. All spaces met enormous acoustical requirements, including the opera rehearsal room and choral recital. The recital hall is the building’s crown jewel. Featuring a 40-foot-high glass wall, the space sets performers against a dramatic backdrop of Lake Michigan and the Chicago skyline. The design needed to consider the overall acoustical challenges of a monumental 42’ x 40’ glass wall and the resultant acoustical reflections within the recital hall. The vertical supports of the glass wall are hung from above and achieve their slenderness by using highly tensioned horizontal cables that are anchored to the recital hall’s massive concrete side walls. Solar/blackout shades are hidden above the ceiling, contained within the accessible cavity to avoid interfering with the acoustics of the hall. The inner glass wall is tilted inward to prevent an echo from being heard by the audience. Acoustical banners can be employed inside the recital hall to fine-tune the acoustics during a performance. The horizontal woven-wood panels are designed to absorb the sound reflections from the glass wall so that the entire room works in harmony to provide a dramatic view behind the performer without compromising acoustics.
