On September 21, Facades+ is coming to Chicago for the first time since 2015. At the conference, speakers from leading architecture, engineering, and facade consultant firms will discuss their bodies of work and lead in-depth workshops. Workshops will cover modular facade design, the challenges and triumphs of large-scale work in Chicago, and how to control the quality, quantity, and directionality of light through facade design.
Dan O’Riley, associate director at Skidmore, Owings & Merrill (SOM), and Lucas Tryggestad, technical director at SOM, are the conference co-chairs.
Located on the southwest corner of Lake Michigan, Chicago is the metropolis of the Great Lakes and has the architectural output to prove it. Since the second half of the 19th century, the city has been at the forefront of design and engineering, pioneering both steel-frame construction and the skyscraper.
For over 80 years, SOM has called the city home. Over the course of its nearly century-long operation, SOM has designed and engineered thousands of projects in over 50 countries. These include the world’s tallest tower, Dubai’s approximately half-mile tall Burj Khalifa, the ongoing conversion of the 1913 Beaux Arts James A. Farley Post Office into the Moynihan Train Hall, and the forcefully engineered Hancock Tower.
Founded in 1979, Chicago’s Kreuck + Sexton has stamped its footprint across the country. Institutional projects such as the Grogan | Dove FBI Building and the Spertus Institute feature faceted and folded glass facades that are coordinated with the functions of interior spaces.
Outside of the realm of supertall and infrastructural projects, local firms such as Landon Bone Baker are demonstrating the creative and sustainable possibilities of affordable and mixed-income housing across Chicagoland. Nearby projects Terra 459, Rosa Parks Apartments, and The Jackson serve as templates that can be emulated across the country.
The rise of Chicago’s broad portfolio of stone and glass-clad skyscrapers could not have occurred without the great density of engineering and facade systems firms located in the region. Ventana and other Chicago firms continue to push the envelope of facade and structural systems with projects such as the Kellogg School of Management, a collaboration with Toronto's KPMB Architects, which features an undulating 160,000 square-foot curtainwall.

The glasshouses are comprised of 893 unique laminated glass panels framed by over 1.25 km of steel mullions.Designed by Heatherwick studio and situated on an industrial site of production since 900AD, Bombay Sapphire’s new distilling operations are distributed into a campus of 23 restored buildings, organized around a widened river and central courtyard. The BREEAM 'outstanding' rated project features two bulbous structures that seemingly float on the river, physically connecting Bombay’s distilling operations to their historic site. Eliot Postma, project leader at Heatherwick studio, cites Britain’s history of glasshouse structures as inspiration for the project: “Modernism has a tendency to flatten buildings, in contrast to the Victorian era’s obsession with three-dimensional shapes and curved domed forms, where a combination of glass and steel is omnipresent. We are quite interested in the dynamism that mullions and steel work might give to a glass facade.” A turning point in the design came with the discovery that excess heat was being produced by machinery through the distilling process. Postma and his team were able to capture this heat, pulling it into the new glasshouse buildings where it was used to grow Mediterranean and tropical plants used by Bombay Sapphire in their trademark gin recipe. Postma calls this an “environmental loop” which is formally represented through a linear reading of the steel mullions, flowing outward, through the still house before landing delicately on the river. Heatherwick studios worked with engineers and contractors to design a self-supporting structural system comprised of laminated glass panels clamped to a rolled steel frame. The geometry of the building envelope was continually refined into the construction phase, ultimately arriving at a solution that balanced material properties with structural requirements. One major problem the design team encountered early in the project was formal gesture of a glass dome introduced highly complex doubly curved surfaces. This became a major constructional problem the design team focused on throughout the development of the project, lasting into the construction phase. Through iterative design models, the team was able to enhance the structural performance of the envelope by pleating the dome form. Additionally, the team optimized their design to work within a specific method of laminated glass panel manufacturing, requiring each panel to be rationalized into a singly curved surface. The assembly process began by erecting a patchwork of steel framework and temporary cross bracing from the ground up. Upon completion of the steel structure, the cross-bracing members were removed one by one as the custom glass inserts were installed. The spirit of this project - its integral connection to the land – is evident in Heatherwick’s upcoming planned projects. On the outcomes of this project, Postma concludes, “This is one of the more complex glass structures that has been constructed. The studio is very interested in how glass can be used as an expressive material in its own right, as a way of creating form out of glass. There is a legacy of these glass houses in our studio today. Seeing the potential of curving glass and its limits and how that can be done reasonably cost effectively to really create quite elaborate form is something that we’ll continue to do as the studio progresses.”
University of Arkansas addition celebrates the future with a contemporary rewrite of Neoclassicism.As head of the architecture department and distinguished professor at the University of Arkansas Fay Jones School of Architecture, Marlon Blackwell was uniquely qualified to oversee the renovation and expansion of the school's home, Vol Walker Hall. To unite the school's landscape architecture, architecture, and interior design departments under one roof for the first time, Blackwell's eponymous firm designed a contemporary west wing to mirror the east bar on the existing Beaux-Arts style building, constructed in the 1930s as the university library. But the Steven L. Anderson Design Center—which tied for Building of the Year in AN's 2014 Best of Design Awards—is more than a container for 37,000 square feet of new studio, seminar, and office space. It is also a teaching tool, a lesson in the evolution of architectural technology writ in concrete, limestone, glass, steel, and zinc. "Our strategy was to create a counterweight to the existing building," explained Blackwell. Rather than a layered steel-frame construction, Marlon Blackwell Architect opted for a post-tensioned concrete structure to convey a sense of mass and volume. "We also wanted to demonstrate what you can do with new technology like post-tensioned concrete, such as introducing a cantilever and introducing a profile that has minimal columns in the spaces," he said. "All of that is a didactic tool for our students to contrast and compare with the load-bearing technology of the existing structure." The exterior of the Steven L. Anderson Design Center also reflects on changes to architectural practice during the last 80 years. "We really wanted to develop a strong profile of the building, in contrast to Vol Walker Hall," said Blackwell. He describes the effect as a figure-ground reversal: where in the older structure the mass of the building is the ground and the windows and ornament act as figure, in the new wing the mass is the figure and the fenestration the ground. To create what Blackwell terms a "condition of resonance" between the Design Center and Vol Walker Hall, the architects engaged Clarkson Consulting to develop an architectural concrete to match the color of a local Arkansas limestone no longer available. They echoed the Indiana limestone on the older wing with panels sourced from a quarry only 50 miles from the original. But instead of grouting the limestone cladding on the new wing, Blackwell chose a limestone rain screen system from Stone Panels. "That allows us to go much thinner but much larger," he said. "Again, we're using the same materials but showing how the advancement of technology allows for a different expression of architecture." The defining feature of the Design Center is the more than 200-foot-long glass and steel curtain wall on the western facade. Knowing that the western exposure would provide the only source of natural light for the new wing, the architects worked to balance the need for light against the threat of solar gain. To complement the existing building, they chose a fascia steel curtain wall custom-fabricated by local company L&L Metal Fabrication. With curtain wall consultants Heitmann & Associates, Blackwell developed a brise soleil comprising 3/4-inch by 18-inch frit glass fins, angled to filter sunlight into the Design Center's 43-foot-deep studios. "What we like about it, too, is that it's one big window," said Blackwell. "It allows it to feel as if we've cut a section right through the building. At night the entire facade becomes a beacon, allowing for a nice interface between the school of architecture and the rest of the community." Other details, including the monolithic concrete pours designed to lighten the Design Center's connection to the ground, and zinc cladding used on the top floor to sharpen the profile of the main body, continue the dialogue between the new structure and its Neoclassical neighbor. "There are a lot of little things that give a tautness to the expression of the new addition, and give it its own identity," said Blackwell. "But at the same time, one of the things we were faithful to was trying to analyze and uncover units of measure and proportion on the old building, and apply that to ours." Perhaps more importantly, the building works as a design school—and Blackwell would know. "There's certainly contrast on the outside," he said. "But there's an almost resonant seamlessness on the inside."
