Old and new technologies combine in renovated anthropology building.Tasked with transforming Harvard's 1971 Tozzer Library into a new home for the university's Anthropology Department, Kennedy & Violich Architecture (KVA) faced a unique set of challenges. In addition to balancing the desire for a distinct architectural identity with the building's literal and metaphorical connection to adjacent structures including Peabody Museum, the architects had to accommodate an expanded program within the old library's footprint and structure. As for Tozzer Library's facade, a mold problem and poor environmental performance meant that preserving the brick exterior was never an option. "It's a generic problem of envelopes from buildings that aren't that old, yet can't stand up to contemporary needs," said principal Sheila Kennedy. "What are you going to do with those buildings? The bold approach here was, 'we're going to build on [the existing] value." By stripping Tozzer Library down to its steel and concrete-slab bones, adding space under a two-story copper roof, and wrapping the exterior in a parametrically-designed brick skin, KVA seamlessly negotiated between Harvard's storied past and the mandates of a 21st-century curriculum. Both Kennedy and founding principal J. Frano Violich are quick to dismiss the notion that the problems with the 1971 building, designed by Boston firm Johnson, Hotvedt and Associates, were anything other than a product of their times. "Attitudes toward energy consumption were very different at the time," said Violich. "[Tozzer Library] was built by intelligent people, but everyone's understanding was different from today." In contrast, he said, for the new Tozzer Anthropology Building, "everyone was on top of every [LEED] point." (The project achieved LEED Gold.) KVA began by substituting 6-inch wall studs for the original 2 1/2-inch studs, making way for improved air circulation and insulation. In addition, they eliminated the potential for mold growth by increasing the air gap between the outside sheeting and the back of the brick veneer from 3/4 inches to 2 inches. With the mechanics of the exterior walls in place, "the challenge, aesthetically, was how do we get a sense of both thickness and thinness in the veneer?" said Violich. Luckily, the question of how to breathe new life into flat surfaces was nothing new for the architects. "At KVA we've been very interested in how one designs with contemporary wall systems, with materials that are thin," explained Kennedy. "How do we express their thinness, but by architectural means and devices give them an architectural thickness, manipulate them formally so there can be a game of thin and thick?" In the case of Tozzer Anthropology Building, the answer was a new entrance pavilion with a three-dimensional brick pattern meant to "seem like carved thick brick—like an archeological find," said Kennedy. Drawing upon their early experiments with digital brick, including those at the University of Pennsylvania Law School building, the designers used parametric design software to tie each brick unit to the building's overall form. "As we manipulated the physical form in 3D, we could see various brick patterns that could develop," explained Kennedy. "It was a hybrid of low-tech and high-tech," she said of the process of zeroing in on corbeling, a brick-stacking technique that allows for overhanging layers. The digitally-derived corbeled texture complemented the depth of ornament found elsewhere around Harvard's campus. "We didn't want to make something that was arbitrary and ornamental, but something that was authentic to our time," said Kennedy. To arrive at a final design for the multi-story entrance wall, the architects again combined cutting-edge technology with traditional expertise. "The actual pattern was achieved through physical experimentation," explained Kennedy. "We did a lot of dry stack work with local masons: We would take the designs out of the computer, then pass them to the masons to test. That was a really fun part of the process." KVA then took what they learned from their real-life experiments back into the virtual world, adjusting the digital design accordingly. Even the flat facades appear unlike typical brick walls, thanks largely to an unusual window arrangement. "When you're looking at the windows, you're not looking at traditional punch windows, or a strip window with a long relieving angle," said Violich. Rather, the windows are shifted to conceal the vertical control joints in the brick. "That helps defuse the veneer quality that brick sometimes brings on," he explained. The floor-to-floor windows further confound expectations by concealing the plenum and—because they are frameless, and punch out rather than in—appearing as much like light monitors as the actual skylights cut into the building's roofline. Tozzer Anthropology Building's recycled-content copper roof completes the dialogue between thick and thin established on the brick facades. "We worked hard in the massing of the design to give a twist to the building," said Kennedy. "That could really only happen in the two new floors." KVA textured the copper roof with vertical standing seams, again using parametric software to arrange different panel types in a corduroy-like pattern. "A lot of times people think advanced facades are super technical, but we can get lost in the technology and why we're using it," observed Kennedy. "[This project] is a good combination of an aesthetic agenda, an architectural agenda, and a technical agenda." For KVA, Tozzer Anthropology Building represents more than just a repurposed campus building. Rather, it offers a provocative answer to one of today's most pressing questions: how to rectify an inherited aesthetic preference for glass with the current push for improved energy efficiency. "Everybody loves glass—we love transparency in architecture," said Kennedy. "But as we move on in our energy transition, we're going to have to develop new ideas about mass and opacity. How can we go back to a pre-modern time, but create something that is contemporary?"
Envelope inspired by history of Dallas' African-American community.For the past 20 years, San Antonio–based Muñoz & Company (formerly Kell Muñoz Architects) has focused primarily on what president and CEO Henry Muñoz III calls "the architecture of identity." The bulk of that work, in turn, has been concentrated on the United States–Mexico border, where the architects collaborated with clients in majority-Latino communities.The commission to design Billy Dade Middle School (in a joint venture with KAI Texas) represented a departure from the firm's usual context. "It struck us that this particular campus had such a rich history and location—in the urban core of the city, and an area where the African-American community has been so important, historically," recalled Muñoz. "It was a great opportunity to explore what that means in the 21st century." Working closely with local residents, Muñoz & Company settled on the metaphor of a quilt, announcing the school's commitment to culturally attuned education with a translucent facade in multicolored glass and illuminated brick. Much of the preparation for the project took place outside the studio. "We approached it not just as designers, but in a more scholarly fashion," said Muñoz. The architects researched the school's namesake—educator, parent, and activist Dr. Billy Earl Dade—through interviews with family members and colleagues as well as archival materials found in a local museum. The linchpin of the design, however, fell into place at a dinner event Muñoz attended. There he asked Claudine Brown, assistant secretary for education and access at the Smithsonian Institution, to help him brainstorm a symbol of cultural identity in the African-American community, one that could help inspire young minds. "Immediately, with no hesitation, she said, 'I think you should look at quilts,'" said Muñoz. As the conversation and further research progressed, he learned that quilts have been used to tell stories, as visual signposts for safety, and as subtle acts of resistance—as well as to meet a basic need for warmth. In addition, said Muñoz, "We found superb artistry, [including] quilting collectives that keep the tradition alive." On the school's exterior, the architects expressed the quilt metaphor with multicolored glass walls fronting diagonal bays. Beyond the reference to quilts as cultural artifacts, the pattern projects a belief in the community's resilience. "That glass wall is an important way of expressing how anything can be woven together," said Muñoz. A patchwork rhythm recurs more subtly in the facade's brick walls, where transparent glass elements preserve a sense of openness. "At night, when the glass curtain wall is so transparent—like a lantern—you also get a sense of that in the brick wall," he explained. The entrance canopy, clad primarily in metal, deepens the material diversity of the building envelope, underlining the design's focus on inclusiveness. "You should be able to be yourself as you walk under it," said Muñoz. The quilt theme continues throughout the interior, notably in the tiled floors (inspired by the work of quilting cooperative Gee's Bend), displays of text from Dade's writings, quilts commissioned for the library, and a collection of salvaged doors lining the lobby walls. "Dade was a really strong mentor in an intergenerational fashion," explained Muñoz. We looked at a speech he made about opportunity and thought, 'What if we harvested doors from the neighborhood?' So in the lobby you see this patchwork of doors, meant to be doors of opportunity." Built to meet Dallas Independent School District's stringent environmental standards, Billy Dade "combined [environmental] sustainability with the idea of cultural sustainability," explained Muñoz. Though in keeping with the firm's track record of community-based design, the project was nonetheless a learning opportunity for the architects. "This was the first time that we've [designed] a school that is multicultural in a different way than what we've been used to working with," he said. "While the population was different, I hope people found something that they can see themselves in."
Curving brick and glass facade heralds Roxbury's resurgence.By locating their new administrative building in beleaguered Roxbury, Boston Public Schools [BPS] made a powerful statement of faith in the area's resurgence."Bringing the BPS right into the heart of Roxbury anchors the redevelopment of the neighborhood," explained Friso van der Steen, manager of international projects at Mecanoo. The Dutch architects collaborated with local firm Sasaki Associates on the project—their first built in the United States—which involved renovating the facades of three historic buildings and weaving them into a coherent whole with a new volume. Described by Mecanoo as "a Bostonian building with a Dutch touch," the structure's curving brick and glass envelope projects a hopeful future for Dudley Square. When Mecanoo and Sasaki won the competition to design the Bruce C. Bolling Municipal Building in 2009, the largely vacant site in Dudley Square, Roxbury's commercial and transportation hub, "contained a number of derelict buildings," recalled van der Steen. These included the 1895 Ferdinand building, which was to be integrated into the project. The architects convinced Mayor Thomas Menino to add two other historic structures to their portfolio: the 1888 Curtis building, and the 1890 Waterman building. "This allowed a design inclusive of the three corners of the triangular plot," said van der Steen. In cooperation with preservation consultants Building Conservation Associates, Mecanoo and Sasaki completely restored the facades of the three existing buildings, each of which was built in a different style. The five-story Ferdinand was constructed of limestone, terra cotta, brick, and granite, and is characterized by large oval windows at the corners and ends of the building, plus a large copper ornamental cornice adorned with cast lions' heads. The red brick Curtis was built in the Queen Anne style, while the Boston Granite Waterman features copper bay windows brought up to snuff by the renovation team. For the new volume, the architects looked both to the surrounding urban fabric and to their own strengths. "Boston has a very rich tradition of using brick," said van der Steen. "Coming from 'the clay country,' The Netherlands, we have used brick in many projects, and we really wanted to use it here to show off the craftsmanship that goes into bricklaying." Working with Iron Spot brick in three different finishes—smooth, velour, and artisan—the design team deployed a variety of bonds—running, stack, and soldier—to create delicate reliefs and shadow effects. "Mecanoo and Sasaki spent a lot of time and effort to design an inviting, permeable public space," said van der Steen. Vertical punch windows render the curving brick facades of the new volume permeable, while the transparent entry invites residents to take advantage of the community resources (including a neighborhood gathering space and facilities for obtaining informal business guidance). A sixth-floor roof deck overlooking downtown Boston makes a visual connection to the city center, and the illuminated mechanical penthouse serves as an orientation point after dark. From the beginning, said van der Steen "we wanted to make one building that united the three old facades. While the historic buildings maintain the feel and scale of Dudley Square, the central volume injects a powerful, tacit modern aesthetic." The word "tacit" is key, he explained, as the discreet character of the undulating brick and glass envelope introduces the new while remaining deferential to the old. "Together, these elements create a rich texture both physically and conceptually, a stepped form which respects the historic volumes of the original buildings."
Concrete, glass, and brick facade balances the promises of the future with respect for the past.When Farmingdale State College administrators commissioned Urbahn Architects to design a new building for the School of Business, they positioned it as a beacon for the school's shift in focus from agriculture to science and technology. But the architects saw a second opportunity in the project: a chance to restore some of the coherence lost during successive campus expansions. "While the building mission, program, and design look forward, the facade includes gestures that preserve its connection with the college's roots," explained Urbahn's Peter Verne. With a high-performance envelope characterized by a checkerboard pattern of concrete composite panels and glazing, the School of Business building achieves a delicate balance between FSC's history and its future. Besides housing the first classrooms on campus equipped with cutting-edge audiovisual technology, the School of Business was designed to foster a new, conversational mode of exchange among faculty and students. "The dean felt strongly that the building should promote casual interaction" among its users, said Verne. To this end, the architects arranged the faculty offices along the front of the building, directly across a circulation spine from the classrooms. The main facade's variable array of Taktl panels and windows "was designed to reflect the office program," said Verne. "The vertical orientation of the panels and glazing suggests a series of smaller spaces within, akin to monastic cells." Urbahn developed the pattern of solids and voids "through a combination of rigor and intuition," he explained, adjusting the window widths to animate the face of the building. The building's larger glazed elements provide visual connections to the historic FSC campus. A full-height curtain wall on the main facade looks out to The Mall, the main academic quadrangle, whose coherence was compromised by the demolition of an older structure. Meanwhile, curtain wall-clad cantilevered lounges at the northeast end of the building, which Verne described as "contemplative treetop-level spaces," face the original heart of the college, including the central ellipse and ornamental gardens. "While past development has steadily moved campus activity to the south and west, this gesture is intended to help reconnect the campus population with its origins and re-energize the historic campus center," said Verne. At the main entrance to the School of Business, a free-standing elevator shaft wrapped in faceted metal panels projects from the facade, reinforcing the exchange between interior and exterior. Urbahn selected the envelope's materials to refer back to different stages of campus growth. "We chose to respect [the historic] palette, updated to reflect a modern understanding of building expression and current building technology," said Verne. The classroom facade, whose horizontal emphasis—delivered through a cantilevered third floor—distinguishes it from the office facade, is clad in brick to echo the first buildings constructed at FSC. Charcoal mica finish aluminum composite (ACM) panels surrounding the stairs and elevator shaft similarly draw on the earliest era of campus building. The material's "iridescence reflects that of the slate roofs on the nearby historic buildings," explained Verne. Even the concrete composite facade was inspired by historic precedent, namely the Brutalist buildings constructed at FSC during the 1960s and 70s. Throughout their exploration of FSC history, the architects nonetheless remained committed to the dean's goal of reinventing academic dialogue. "I love how much the building design both shapes and is shaped by social interaction," said Verne. "Ever since the main facade began to take its final configuration, I've enjoyed imagining the negotiations between professors and administration over who gets the offices with the bigger windows."
