Abstract
The case study describes the challenges encountered in designing and building the curtain wall window system of the new Spertus Institute—ten‐story building in Chicago, IL, designed by Krueck + Sexton Architects, opened in November 2007. The multifaceted glass facade, overlooking Michigan Avenue into Grant Park and Lake Michigan, is formed by complex folds in three dimensions and supported by a customized structural system. Noise isolation to the urban environment and between diverse program spaces along the building’s glass front such as exhibition galleries, library, administrative offices, multimedia classrooms, museum, children’s center, board room, space for community events and celebrations, and café is a high priority. Innovative design details were developed to preserve the vertical sound isolation from floor to floor along the jagged slab edges and to address the horizontal sound isolation between the sloped panes of glass. This paper presents in detail the program functions, design considerations, options explored, and test results of the final solution.
