"I don't have a lot of confidence that the current plan commission would observe a plan that was adopted back in 2004," he said. Now a surface parking lot, the site is one of only two gaps in the continuous 1.3-mile cliff wall along the west side of Michigan Avenue between Randolph Street and Roosevelt Road. In the early-2000s condo boom, it was the proposed site of a 40-story condominium tower, but developer Warren Barr was hit with a foreclosure suit and lost the property to First American Bank, which still owns it. First American representatives did not respond to requests for comment.If it happens, the project would hardly be the firm's first in their hometown. JAHN (mostly under their prior moniker, Murphy/Jahn) designed the United Airlines terminal at O'Hare and the Ogilvie Metra station downtown, as well as the State of Illinois Center (the Thompson Center), 600 N. Fairbanks, 1 S. Wacker Dr., and others. Yet lately most of the firm's high-profile work has been abroad.
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."
Parallel facade systems in contrasting materials mark the edge of development on a reimagined campus.The new Rutgers Business School in Piscataway, New Jersey, is more than a collection of classrooms and offices. The building, designed by TEN Arquitectos, is a linchpin of the university’s Livingston campus, reconceived as an urban center for graduate studies and continuing education. “It established a frame,” said project manager James Carse, whose firm created a vision plan for the campus starting in the late 2000s. “We were interested in really marking the edge of campus to motivate future development to respect the campus boundary, rather than allowing or suggesting that this was a pervasive sprawl. We wanted to make sure this would set a pattern where infill would happen.” The Rutgers Business School’s tripartite envelope reinforces the distinction between outside and inside. While the sides of the building facing the boundary line are enclosed in folded anodized aluminum panels, the glass curtain walls opposite create a visual dialogue with the rest of campus. In TEN Arquitectos’ early designs, the difference between the building’s outer and inner surfaces was not so stark. “We initially thought of [the entire envelope] as being more open,” said Carse. But budget constraints combined with university requirements regarding glazing in classrooms to suggest that the architects move away from an all-glass enclosure. “There was an ability to deploy the curtain wall over only a certain amount of the building in a responsible way,” said Carse. “We let the inside push back against the outside and suggest that this be more solid.” At the same time, explained Carse, “we didn’t want it to feel unchanging and heavy.” Working with Front Inc., TEN Arquitectos designed an anodized aluminum rain screen system, manufactured by Mohawk Metal Manufacturing & Sales, that incorporates an apparently random fold pattern to provide texture. (Thorton Tomasetti provided additional consulting and inspection services during construction.) After making aesthetic modifications in Rhino and 3ds Max, the architects ran their digital model through eQUEST energy analysis software to determine an angle of inclination that would prevent snow from accumulating on the folds. They came up with four standard dimensions that could be combined for a varied effect. “It’s a pretty amazing condition that’s been created with the variegated folded panels that face Avenue E and preserve and pick up the western sunlight as the sun sets,” said Carse. “The building changes throughout the day and picks up texture from its surroundings. The anodized aluminum plays off that nature of change and creates a softer facade than you’d expect from the use of metal itself.” The campus-facing sides of the building feature frit glass curtain walls fabricated by Beijing Jangho Curtain Wall Co. (Jangho) with glass from Xinyi Glass Holdings Limited. “We used the fritted glass to meet the solar performance that we were going for without completely exposing them,” said Carse, who noted that the walls appear nearly transparent at dusk and later, when the interior lights are on. “That’s part of the nature of the building,” he said. “The business school itself has classes going from around 8:30 a.m. until about 10 p.m., so the daily life is not just during the day. The building is really alive during those times and we wanted to make that evident.” During the day, the frit glass facade’s extra-wide mullions maximize the amount of daylight that filters into the offices and classrooms. The third component of the Rutgers Business School envelope is a transparent glass curtain wall introduced between the two primary facade systems. Besides serving as an intermediary between the anodized aluminum and frit glass surfaces, the transparent glass elements mark possible points of connection to future buildings as the campus continues to densify. “It allowed us infill,” said Carse. “This project served as a gateway building literally and figuratively,” said Carse. Cars entering campus from Route 18 pass directly through the Rutgers Business School building, its upper stories perched on canted columns. Though designed to indicate the campus’s outside edge—the end of development—the structure’s vital facade simultaneously signals a beginning, a freshly urban approach to campus design within a former suburban stronghold.
A high-performance facade weaves a diverse program into a single volume.The School of Law at the University of Baltimore was founded nearly nine decades ago, but for most of that time its classrooms, offices, library, and clinics were scattered among several downtown buildings. That changed last year, with the opening of the John and Frances Angelos Law Center. Designed by Behnisch Architekten with Ayers Saint Gross, the Angelos Law Center unites a diverse program within a single 12-story structure. Its checkerboard envelope, which won Best Facade in AN’s 2014 Best of Design Awards, weaves the building’s three principal components—a classroom and office wing, the library, and a central atrium—into a single volume. In addition, the facade positions the university on the cutting edge of sustainable design. Its integrated approach to energy efficiency has helped the Angelos Law Center win several green-building prizes, and set it on track to achieve LEED platinum status. Behnisch Architekten took a tripartite approach to the design of the facade. The architects wrapped the portion of the building dedicated to offices and classrooms with an aluminum plate and punched window system. “This is the kind of facade that works very well with the kinds of spaces behind it, because those tend to be a bit more regulated and modular in the way they are allocated,” said partner Matt Noblett. For the library, the uppermost of the building’s two L-shaped volumes, the designers chose a frit glass with a pattern they call a basket weave. “The library, from a program perspective, is kind of a big soup,” said Noblett. There are group study spaces, offices, and, of course, the stacks. “[W]e wanted to find a way in the facade to do [something] more neutral, less specific,” he explained. “The basket weave is less specific in how the articulation of the facade related to the program behind it.” The third segment of the facade, transparent glass enclosing the building’s atrium, draws the two other volumes together. The architects developed a unique sustainability strategy for each section of the building. For the office block, National Enclosure Company fabricated a unitized curtain system comprising the window surface, exterior blinds, and a glass rain screen. The Hunter Douglas Nysan blinds move up and down according to an automated program that operates the top one-third and bottom two-thirds of the windows separately. “It’s remarkable to look at the specific data, to see how much more of the year you’re able to maintain comfort without excessive amounts of air conditioning when you have an exterior sunshading system,” said Noblett, whose firm worked with Transsolar on the building’s climate engineering. Outside the blinds is a low-iron laminated glass rain screen mounted on aluminum brackets. While the architects initially designed the rain screen to protect the blinds, it also solved an architectural problem. “It had a tendency to reunify all of the facade into one building,” he explained. “The more you perforate, the less you read as one volume. By essentially shrink-wrapping [the offices and classrooms], you start to read it again as a [single] volume.” The library at the Angelos Law Center is faced with frit glass from Viracon. “We did a lot of study with the manufacturer” to determine the gradient pattern, said Noblett. “What we wanted it to read was as purely white as possible. We wanted the ceramic as close to the surface as possible.” The goal was to reduce solar gain to the bare minimum. “If you were designing the building and didn’t care how it looked, you would just build a solid wall,” said Noblett. “The idea to add frit to make the wall essentially solid, [but] from the interior of the library it still feels like it’s open.” Outside the atrium, Behnisch Architekten installed a fixed brise soleil by National Enclosure Company on the south and west sides. The north side they left uncovered. All of the Angelos Law Center’s windows are operable, which, while not unheard of, is still unusual in a non-residential setting. “It’s hard to argue with a building where you can get comfortable by opening windows versus sealing up and running the air,” said Noblett. Noblett describes designing a high-performance facade as “this game you’re constantly playing between how much light comes in and how much solar gain [results].” By that analogy, the Angelos Law Center is a check mark in Behnisch Architekten’s win column.
Multiple layers of glass combine with corrugated metal panels to balance visibility and privacy in the University of Pennsylvania's new research center.As an experiment in interdisciplinary research, the Krishna P. Singh Center for Nanotechnology at the University of Pennsylvania is not a typical science center. It follows, then, that the university would not want a typical laboratory building, with a central corridor and minimal public space. Instead, the University of Pennsylvania asked Weiss/Manfredi to design the Singh Center around two principles. First, the building should create a new campus green for the school of engineering and applied sciences, in keeping with both the university’s and the city’s tradition of building around open quads. Second, the building should maximize natural light and visibility without compromising the integrity of the research itself. The most outstanding feature of Weiss/Manfredi’s design is the multi-layered glass curtain wall on the Walnut Street side of the building, which was designed with facade consultant Heintges and installed by National Glass & Metal Company. The outermost layer of glass, Guardian SunGuard AG 50 low-E on UltraWhite, which separates the building’s public spaces from the courtyard, achieves transparency while minimizing solar heat gain (the building is on track to achieve LEED Gold certification). It comprises an exterior etched panel by Walker Glass Co. wedded to a reflective panel with interior frit by JE Berkowitz. The etching and frit pattern varies from one part of the building to the next, for a total of five glass pattern modules. “The idea with that pattern was that where views out are most important, it’s most transparent,” said Weiss/Manfredi senior project architect Mike Harshman. “Where it’s more an issue of daylight, it’s more opaque.” The second layer of glass divides the Singh Center’s public spaces from its laboratory spaces. There, Weiss/Manfredi installed a laminated assembly with two layers of translucent frit. Again, the architects aimed for balance, this time between privacy and views out. Interior solar shades allow occupants to shut out daylight—or the eyes of passersby—when needed. On the first floor, an amber glass interlayer demarcates the research center’s 10,000-square-foot Bay/Chase Cleanroom. The color protects the interior of the cleanroom from ultraviolet rays and specific light wavelengths in the visible spectrum without walling it off completely. “Cleanrooms are typically a closed thing, but you can walk in and see everything going on in [there],” said Harshman. Glazed in interior fritted glass, write-up offices front the laboratories themselves, allowing light to enter the general labs. “We really saw the sections—the exterior glass, interior, and glass on [the] labs—as one assembly,” explained Harshman. The design allows daylight to penetrate deep into the building, while the combination of patterned glass and solar shades protects both the researchers and their experiments. The Singh Center facade is not all glass, however. Far from it. “From some views it looks like it’s very glassy, but the glass only represents one-third [of the building envelope],” said Harshman. “The rest is opaque and very insulated. The question became how to clad that surface.” Weiss/Manfredi explored a number of materials, including champagne-colored metal to echo the surrounding brick buildings. Ultimately the University of Pennsylvania chose silver anodized aluminum plate panels, explained Harshman, “because for them the context was technology.” The corrugated panels, which were fabricated and installed by Wyatt Incorporated with a custom finish by Spectrum Metal Finishing, were hung as a rain screen system over a prefabricated highly insulated exterior backup wall. “[There was] a great interest on Penn’s part that the project would have an aspect about scale and light. They liked the idea of the corrugated panels catching light at different times of the day,” said Harshman. The logic of the Singh Center facade culminates in the Forum, the multipurpose conference space that cantilevers over the courtyard. Its back and sides wrapped in protective metal, the Forum’s front wall is fritted glass overlooking the main campus. As a result, the place where researchers present their work is also the most connected to the university and the community around it. In the Singh Center, the University of Pennsylvania did not have to choose between openness and an effective research environment. They achieved both, with a building that turns traditional laboratory design on its head.
