The restoration project conducted by Krueck & Sexton Architects has been, like the previous restorations, an excellent recovery work. See more here. (Restoring Mies van der Rohe: 860-880 Lake Shore Drive.)
Memory of project
Crown Hall, Illinois Institute of Technology: S. R. Crown Hall is recognized as one of the supreme achievements of twentieth century architect, Mies van der Rohe. Constructed in 1956 for the IIT College of Architecture, this masterpiece of modern architecture required restoration and renovation after nearly fifty years of continuous use.
The restoration scope included two phases: phase I restored landscape and façade, phase II includes measures to improve mechanical system and make the building more efficient. Ron Krueck and Mark Sexton, both IIT graduates, possessed several unique qualifications for this undertaking. As one the foremost practitioners of modern architecture, they have continued many of the aesthetic lines of inquiry explored by Mies, and embodied in Crown Hall, and have found their practice on the possibilities of glass architecture.
Phase I included a restoration of the original landscape, accessibility upgrades, and important pragmatic upgrades to the classrooms, toilet rooms and exhaust systems, and an overhaul, reglazing and recoating of the façade. All components of the curtain wall were individually sandblasted down to base metal finish, a process necessary to clear the metal of corrosion that had accumulated over the past 50 years. All glass was replaced to matched to original intent of Mies van der Rohe and to perform against current building codes. This meant low-iron safety glass with high performance coatings. In-situ glass mock-ups were performed to review contemporary glass against the benchmark of the existing building, helping to ensure the closest match (for both clear and sandblasted glass) was chosen. Thicker glass required deeper steel stops. In order to accommodate the bite required, Krueck+Sexton revised the steel stops section to maintain the thin outward profile, but to also accommodate the bite required, helping to maintain Mies’s original design intent but also accommodate the thicker glass. Construction phasing was meticulously planned to accommodate the academic year without any disruption to scheduled classes and to perform the intensive façade work over the 3-month summer holiday.
Since the building is both a City of Chicago Landmark and listed on the National Register of Historic Places, every element of the project underwent a rigorous team, client and peer review process.
A critical part of the restoration project is an overall greening of Crown Hall. As part of Phase II, the building’s original assisted natural ventilation system will be restored. The radiant floor system will both heat and cool. A new building management system will link the HVAC system, CO2 monitors, dimmable lighting, automated blinds and daylight sensors and result in 40% less energy consumption.
The restoration has received numerous awards, including the Landmarks Preservation Council of Illinois "Project of the Year" award and the American Institute of Architects Chicago Chapter "Honor Award".
