Brought to you with support fromOn June 25, Facades+ is returning to Boston for the fourth year in a row. The conference, organized by The Architect's Newspaper, is a full-day event split between a morning symposium and an afternoon of workshops led by top AEC practitioners. Leers Weinzapfel Associates (LWA), a Boston-based firm with projects nationwide, is co-chairing the conference. Panels for the conference will focus on the changes underway in Boston, ranging from new educational structures, the city's new tallest residential building, and historic preservation projects. Participants for the conference's symposium and workshops include Behnisch Architekten, Knippers Helbig Advanced Engineering, Pei Cobb Freed & Partners, Bruner / Cott, Arrowstreet, Consigli Construction, Walter P. Moore, Autodesk, Atelier Ten, Harvard GSD, the Wyss Institute, and Okalux. In this interview with The Architect's Newspaper, LWA's designer and business development representative Zhanina Boyadzhieva and associate Kevin Bell, the conference co-chairs, discuss their firm's growing body of work and the developmental trends within the city of Boston. The Architect's Newspaper: Boston is known as a relatively quiet city with a predominantly low-slung skyline. How is current development reshaping that identity and what does it mean for the future? Zhanina Boyadzhieva: Boston is indeed a “quiet” city, but it is also a hub of innovation and creative thinking. In the past few years, we have observed dynamic design work, largely by local firms, on several fronts: 1) creative re-envisioning of historical landmarks through readaptations and additions such as Smith Center at Harvard University and Congress Square in downtown Boston 2) careful insertions of new landmarks in the skyline such as One Dalton 3) fast development and growth of existing or new resilient neighborhoods such as Harvard’s Allston campus. Each design solution addresses unique urban conditions and entails holistic thinking about city planning, resilience, and sustainability, coupled with a sense of function, form, materiality, and human experience. Naturally, facades combine all of these considerations and become dominant players in the reshaping of cities. The diversity of approaches we observe—controlled material juxtapositions of old and new, sculptural form-making, and playful screening strategies—are testaments to ongoing design experimentations here. There is a search for new methods to address creative reuse, high performance, material fabrication, and user experience. AN: The city possesses one of America's largest concentrations of brutalist buildings, as well as large historic districts. How can Boston embrace its heritage while moving forward? Kevin Bell: The rich building history of Boston, including modern landmarks like City Hall, and its brutalist companions make for wonderful urban fabric for intervention and a great place for an architect to practice. This history should serve to elevate our expectations for new buildings and major renovations in the city. The recent warming to Boston’s brutalism, its strong geometry and bare materials, is welcome, encouraging designers to consider rather ignore these local icons. It presents the opportunity to consider adaptation and re-envisioning through sustainability’s lenses, the human experience, and materiality. If we can dramatically improve the energy efficiency and human use in these sensitive historic buildings, we can achieve the same in new construction and create a model for continued improvement. AN: What innovative enclosure practices is LWA currently executing? KB: As a firm, we have a legacy of designing efficiently in an urban context. Often, our site is an existing historic building or a tightly constrained sliver of land, or sometimes, there's no site at all. This fosters a sensibility within the studio toward compact volumes, materially efficient, with taut fitted skins, a practice that serves us well as we work to make evermore energy efficient and sustainable buildings. We're also redefining our performance expectations around our clients' commitments to energy efficiency, many of whom have established operational carbon neutrality as their aim by mid-century. The enclosures we design today will be part of that efficiency equation. They must be considered to be part of a carbon neutral organizational environment as a performance baseline above simple compliance with today's codes or target certifications. Envelope performance, especially the use of innovative glazing materials, is a logical extension of the way we think about reactive, efficient space and energy efficiency targets in building enclosure design. Our Dartmouth Dana Hall renovation and addition, under construction now, is an example of this process and practice. We worked closely with the college to define a program for building reuse around its energy use reduction targets that dramatically improved envelope efficiency. Through the design process, we worked with our design and construction partners to continually refine the design while holding to incremental improvement in energy efficiency at each step; our modeled efficiency improved even as we moved through cost reduction exercises. The result is a highly insulated building, triple glazed throughout, with a thermally improved, south-facing glass curtainwall system combining vacuum insulated high-performance glass modules with integrally solar shaded, triple glazed vision glass as part of a building with a predicted energy use index (pEUI) in the middle twenties before the introduction of site renewables. AN: Which materials do you believe are reshaping facade practices? ZB: Materials are the agents of larger design strategies shaping the practice such as resilience, sustainability, and human experience. The aim to rethink and cherish historical buildings, for example, leads to a careful layering of existing and new materials that contrast and simultaneously enhance each other. Heavy textured concrete at the Smith Center is supplemented by light and open transparent glass, green walls and warm wood. Traditional brick block at Congress Square is juxtaposed with a floating glass box on top of sculptural fiber-reinforced plastic panels. On the other hand, the vision to create new landmarks that celebrate and reshape the Boston skyline result in the careful sculpting of distinctive volumes as in One Dalton, a tall glass skyscraper with careful incisions of exterior carved spaces for human use. Finally, the goal to produce energy efficient but playful envelopes leads to a game of patterns composed of an inner insulated layer with an outer wrapper of perforated metal screens or angled aluminum fins. Each choice of material and its manipulation reflects a larger vision to create a unique experience in the city. Further information regarding Facades+ Boston can be found here.

Brought to you with support fromBehnisch Architekten's AGORA Pôle de Recherche Sur le Cancer in Lausanne, Switzerland, overlooks the historic core of the centuries-old city from a prominent ridgeline within the city center, contorting itself into multiple planes of curtain wall shaded by a continuous band of aluminum apertures. As an approximately 240,000-square-foot cancer research institute, the complex's program calls for easily navigable and well-illuminated corridors linking offices and research spaces for hundreds of practitioners. Additionally, the central meeting place of the facility—dubbed "AGORA" in homage to the ancient Greek sphere of public assembly—is topped with a semi-translucent ETFE canopy. "AGORA was our first effort at developing a stationary, responsive solar shading system, which developed out of the original competition design," said Behnisch Partner Robert Matthew Noblett. "The concept is essentially moving the sophisticated technology involved in responding to solar angles that change throughout the day and year and deploying it on the design side in the form of parametric modeling and fabrication, optimizing shading elements according to orientation and season."
Facades+ New York conference, a two-day event at the beginning of April focused on the design and performance of facades.The second skin of the building consists of a continuous aluminum screen that runs across the underlying glazed facade. Each of the facade's nine distinct planes is shaded with a unique variation of the screen; the skin on the north has relatively large openings while that on the south is more constrained. The panels consist of two folded aluminum pieces joined together to resist bending. For the shading requirements of the building, Behnisch Architekten developed a set of parametric guidelines for Rhino, Grasshopper, and AutoCAD. The length of the "P" line, the protruding-perforated aluminum flap, was determined by the "V" plane perpendicular to the facade, and the "H" plane parallel to the facade. After producing scores of digital simulations for sun and heat protection, light enhancement and glare, the design team built multiple physical models that were tested under artificial lighting. "The optimization of the facade is controlled both by the aperture and its orientation, which respond to the orientation of the glass surface and its type of glass," said the design team. "The same solar performance can be achieved for every given angle of the sun with an array of different geometries that offer all the different view openings and qualities." The second skin is located approximately 2.6 feet from the inner facade, allowing for the insertion of a maintenance catwalk and over half-a-foot of space for the secondary structure supporting the shading panels. The secondary structure is composed of a series of diagonal steel rails running parallel to each other. Every short end of the panels are connected to the steel rails via simple fastener connections. Armatures extending from the inner facade support both the catwalk and the steel rail system. According to the design team, one of the greatest challenges of the project was the connection of the bands of aluminum apertures across nine unique facade planes. To maintain the visual continuity of the second skin, Behnisch Architekten collaborated with manufacturer and installer Sottas SA to produce a unique seam of aluminum pieces for each corner. In the coming years, Behnisch will monitor the performance of the complex's enclosure system. Lessons learned from the study of the structure will inform the design of similar systems for ongoing projects such as Harvard's School of Engineering an Applied Sciences and the ARENA HQ in Germany. Robert Matthew Noblett will be joining a panel, "Facade Syntax: Changing Context and International Regulations," at The Architect's Newspaper's upcoming
Brought to you with support fromOn April 4 and 5, Facades+ is returning to New York for the eighth year in a row. Organized by The Architect's Newspaper, the New York conference brings together leading AEC practitioners for a robust full-day symposium with a second day of intensive workshops led by manufacturers, architects, and engineers. Doriana and Massimiliano Fuksas, and Toshiko Mori are respectively leading the morning and afternoon keynote addresses for the symposium. In between the keynote addresses, representatives from Renzo Piano Building Workshop, Permasteelisa, Cooper Union, Gensler, Heintges, Atelier 10, Transsolar, Walter P. Moore, Schüco, Frener & Reifer, and Behnisch Architekten, will be on hand to discuss recently completed innovative projects. New York-and-Frankfurt based practice 1100 Architect is co-chairing the conference. In anticipation of the conference, 1100 Architect's Juergen Riehm sat down with AN to discuss the firm's ongoing work, the conference's program, and trends reshaping New York City's built environment. The Architect's Newspaper: It is safe to say that New York City is undergoing a tremendous period of growth. What do you perceive to be the most exciting trends within the city? Juergen Riehm: You’re right; New York City is undergoing big change and growth. I would say that one of the big drivers of that change—and one of the exciting trends—is the investment in the city’s public spaces. There has been such transformation along the waterfronts and in parks across all five boroughs, and that has really catalyzed growth. We have worked with several city agencies for many years and in different ways, including with the Department of Parks & Recreation, which has been an exciting partnership, contributing to these changes. One of the projects we currently have in design for NYC Parks is a new community center in East Flatbush, Brooklyn. There, we are designing a 33,000-square-foot community center. The facade will perform in a number of ways. Since it is a community center, we want it to be as open and transparent as possible, and it also needs to be robust and durable. The building is on track to meet the city’s new sustainability standards LL31/32 and LEED Gold. There has been so much attention on new large-scale developments like Hudson Yards or the supertall towers in Midtown, but one of the other exciting trends right now is the renewed attention on optimizing the performance of existing buildings. It is something we will address during Facades+ NYC, but there is great work happening now on restorations of historic buildings—at the Ford Foundation or the United Nations, for example—that not only addresses decades of wear and tear, but that also brings these structures up to full 21st-century performance standards. AN: 1100 Architect is based in both New York and Frankfurt. What are the greatest benefits of operating a trans-Atlantic practice? JR: Our practice has always been deeply rooted in New York—just as it has also always had an international footprint. From our earliest days, we delivered projects overseas, so it seems like part of 1100 Architect’s DNA to have an ongoing dialogue with other geographies. We launched our Frankfurt office about 15 years ago, and, as you suggest, it does bring benefits. In general, we find that it has a reciprocal sharpening effect, with each location informing the other with different materials, technologies, and delivery methods. AN: Which projects are 1100 Architect currently working on, or recently completed, that demonstrate the firm's longstanding demonstration of sustainable enclosures? JR: Well, the NYC Parks community center in East Flatbush is a good example. It’s an exciting project in many ways—including the fact that we are designing it to the City’s new LL31/32 sustainability standards. In every way, we are really pushing for optimal performance, and the high-performance envelope plays an integral role toward that end. We were recently awarded a contract with the U.S. Department of State, so we are poised to begin working on diplomatic facilities around the world, so the safety and security of facade systems will be a paramount consideration. In Germany, we are renovating a 19,000-seat soccer stadium and adding a new training facility, using an innovative and high-performance channel-glass facade. We recently completed a Passive House–certified kindergarten there, too, which involved a high-performance facade. AN: Are there any techniques and materials used in Germany or the EU that should be adopted in the United States? JR: In Germany, I find that there is a more closely integrated relationship between government, the building industry, and the architectural profession. With environmental standards, for example, the goals set by the government are quite ambitious, and it has resulted in a closely integrated process of meeting those goals. In this moment of deregulation in the U.S., it seems like a good time to consider the value of the government’s role in moving toward energy efficiency. AN: Where do you see the industry heading in the coming years? JR: By necessity, I see it moving toward higher standards of energy performance. Climate science is calling for it and the marketplace is increasingly looking for it, so the architecture and building industry will need to deliver. And as I mentioned at the start of this conversation, I also think there will be a lot of focus on updating existing buildings to enhance performance.

Construction is underway on the renovation and expansion of Portland State University School of Business Administration. Behnisch Architekten is collaborating with local SRG Partnership on the downtown Portland design, which strives to better connect the school to the urban fabric and uphold the school’s sustainable values. As such, they are targeting a LEED Platinum rating. “PSU is the largest university in Oregon, it's urban but the current business school is housed in an unremarkable building and doesn’t have an identity,” noted architect Matt Noblett, a partner in Behnisch Architekten’s Boston office. “The school has an ethos of responsible capitalism, which is a progressive approach to business and making money that is not at the expense of humanity and sustainability.” Slated to open in 2017, the new design is a 35,000-square-foot addition to the existing 100,000-square-foot business school. A daylight-filled, five-story atrium will provide circulation between the new and renovated areas while offering space for informal meetings and study areas. Both the new structure and the 1970s building will house classrooms, faculty administrative offices, and business incubators. Noblett added that the new structure would be clad in a unifying Alaskan Cedar. Critical to the new design is the connection to the urban fabric. The site is a typical 200-foot-by-200-foot Portland city block. The architects’ scheme harnesses pedestrian activity on Montgomery Street and cuts a path through the school to link to 6th Avenue, Broadway and Harrison Street. The hope is that by providing exterior plazas and a cross-block connection the design will foster a vibrant public space. Organized vertically from more public to more private, the new building has what Noblett calls a “natural stratification.” The ground floor will house retail spaces, while classroom and event spaces cantilever over the outdoor areas. “The existing building was deaf to public interaction and the school had a craving to link back to the public and show people what they do—they wanted to open up the school and make it part of the urban environment,” Noblett explained.
Harvard University has submitted plans by Behnisch Architekten with the Boston Redevelopment Authority (BRA) for a six story, 500,000-square-foot science and engineering complex on its Allston campus. Stuttgart- and Boston-based Behnisch Architekten is designing new laboratories, classroom space, research facilities, and retail space for the John A. Paulson School of Engineering and Applied Sciences. The home of the Earthwatch Institute, at 114 Western Avenue, will also be renovated by the architects. The design responds to the layout of Harvard Yard, a "human scale" network of communal space. Like most of Behnisch Architekten's projects, the structure will capitalize on ecological principles: natural ventilation, renewable energy from geothermal and wind, roof gardens, and heat recovery and retention. In a statement, Matt Noblett, partner at Behnisch Architekten, explained the synergistic aspects of his firm's design: “The design of the Science and Engineering Complex project pulls together a number of threads of contemporary life certain to influence coming generations: the engineering enterprise as a decisive influence in the discovery and resolution of some of the world’s most intractable problems; cross-disciplinary efforts as critical to major research initiatives; and genuine leadership in the area of sustainable design and urban development.”
Behnisch Architekten has big, green aspirations for its latest project, the EpiCenter, fittingly located in Boston’s Innovation District, the burgeoning neighborhood designed for such far-reaching goals. The firm just unveiled plans for a new expanded headquarters for the non-profit, Artists for Humanity (AFH), an organization dedicated to helping underserved youth through paid employment opportunities in the arts. According to Behnisch, the addition will make the existing LEED Platinum certified building—the city’s first—designed by local firm Arrrowstreet, even greener, with the hope of becoming the largest energy positive commercial building on the East Coast. The building already was an AIA COTE Top Ten winner. The expansion will add 63,500 square feet of space to the original building to accommodate more areas for the young artists as well as larger galleries and new studios. A retail store and café will overlook a new 1.5-acre park. The firm will employ a number of tactics to minimize the building’s carbon footprint, including the use of recycled and locally sourced materials, passive solar strategies to maximize daylight, specific type of glass to mitigate solar heat gain, a heat recovery system, and storm water management. To send energy back to the grid, and achieve its energy positive target, the firm will implement different solutions to generate its own electricity such as mounting photovoltaic arrays and utilizing geothermal production. While the design is still in its preliminary stage, the building is slated to open in November 2016.
Strength and softness meet in a metal mesh room divider.Interior dividers can be functional to a fault. If a partition is all you need, then even drywall would do the trick. A custom-built metal curtain in the University of Baltimore’s new law building, however, brings an architectural sensibility to the problem of dividing one space into two. The curtain bisects the lobby with stainless steel, woven into mesh for a unique and uncharacteristically soft texture. Maryland-based Cambridge Architectural engineered and installed the custom mesh curtain for the John and Frances Angelos Law Center at the University of Baltimore. The building, designed by Behnisch Architekten and Ayers Saint Gross, won best facade in AN's first annual Best of Design Awards. The divider is a continuous 33-foot curtain of architectural stainless steel in the building’s seventh-floor lobby. (A second divider, also designed by Cambridge Architectural, is located near the snack bar on the ground floor.) Made of small triangular volumes between a mesh weave, the curtain’s opacity varies based on the angle of the viewer. The Angelos Law Center curtain is longer than previous applications of similar systems, said Cambridge Architectural’s engineering manager Jim Mitchell. Many dividers the company has installed are less than 20 feet long, and are often split in the middle. The tabs and aluminum tracks that hold the 500-pound curtain in place are marine-grade—that is, they are fit for sailing rigs. The metal curtain can be pulled open and closed like a security gate, but it retains the smooth movement and look of a curtain. “It gives it the appearance more of a tapestry than a panel, which typically is tensioned and rigid,” said Mitchell. The fabric-like texture is made possible by the closely woven pattern. “The larger ones look more industrial, and they’re a little bulky when they fold up. But the smaller spirals tend to fold and roll together.” To make the tightly knit weave, Cambridge Architectural flipped the typical orientation of mesh curtains, running metal crimp rods vertically across the mesh instead of horizontally. The crimp rods, welded once they are woven through, join the triangular volumes of the curtain. The designers modeled the curtain components in SolidWorks before sending the data to production. In the Angelos Law Center, the orientation of the weave was especially important because of the lobby's tall ceilings. Whether it is locked closed as a true divider, or left partially open like a less substantial curtain, the stainless steel weave is durable and elegant. “The architects didn’t want the standard security grate that you see at the shopping mall,” said Mitchell. “They wanted something with that architectural look to it. Our mesh kind of fits that bill. It’s durable and it’s metal so it’s going to last forever, but yet it still has that look. So it doesn’t look like you’re pulling down a screen in front of RadioShack.”
The AIA's Committee on the Environment (COTE) has announced the winners of its annual sustainability awards program. Now in its 18th year, the COTE awards celebrate green architecture, design, and technology. According to a press release, the winning projects must “make a positive contribution to their communities, improve comfort for building occupants and reduce environmental impacts.” Each of the ten winners will be officially honored at the AIA's National Convention and Design Exhibition in Chicago later this year, but, in the meantime, here’s a closer look at the 10 winners. Arizona State University Student Health Services (Pictured at top) Tempe, Arizona Lake|Flato Architects + Orcutt|Winslow According to the AIA: “The Arizona State University (ASU) Health Services Building is an adaptive reuse project that transformed the existing sterile and inefficient clinic into a clearly organized, efficient, and welcoming facility. The design imbues the new facility with a sense of health and wellness that leverages Tempe’s natural environment and contributes to a more cohesive pedestrian oriented campus. The building’s energy performance is 49% below ASHRAE 90.1-2007, exceeding the current target of the 2030 Challenge. The facility achieved LEED Platinum certification and is one of the best energy performers on campus as evidenced by ASU’s Campus Metabolism interactive web-tool tracking real-time resource use.” Bud Clark Commons Portland, Oregon Holst Architecture According to the AIA: “As a centerpiece of Portland’s 10-Year Plan to End Homelessness, this LEED Platinum project provides a continuum of services to help transition homeless individuals toward stable, permanent living arrangements. The architecture helps achieve this goal with a walk-in day center with public courtyard and access to support services; a 90-bed temporary shelter; and a separate and secure entrance to 130 efficient, furnished studio apartments for homeless individuals seeking permanent housing. The building’s design aims to deinstitutionalize services and housing for the most vulnerable in our population. Sustainable features include large-scale graywater recycling, zero stormwater runoff, solar hot water, and a high-performance envelope, resulting in energy savings estimated at $60,000 annually.” Bushwick Inlet Park Brooklyn, New York Kiss + Cathcart, Architects According to the AIA: “This project is the first phase of the transformation of the Greenpoint–Williamsburg waterfront from a decaying industrial strip to a multifaceted public park. The design team integrated a program of playfields, public meeting rooms, classrooms, and park maintenance facilities, into a city-block sized site. The park building becomes a green hill on the west side, making 100% of the site usable to the public, and offering views to Manhattan. Below the green roof is a complex of building systems – ground source heat pump wells, rainwater harvest and storage, and drip irrigation. A solar trellis produces half the total energy used in the building.” Edith Green-Wendell Wyatt (EGWW) Federal Building Modernization Portland, Oregon SERA Architects in association with Cutler Anderson Architects According to the AIA: “On track to be one of the lowest energy-use buildings in the U.S., EGWW is a model for U.S. General Services Administration nationwide. The project’s goal was to transform the existing building from an aging, energy hog to one of the premiere environmentally-friendly buildings in the nation. With a unique facade of “reeds”, light shelf /sunshades designed by orientation and a roof canopy that supports a 180 kW photovoltaic array while collecting rainwater, EGWW pushes the boundaries for innovative sustainable deign strategies. In addition to the energy improvements, the design reveals the history of the building, exposing the artifacts of the original builders.” Gateway Center - SUNY-ESF College of Environmental Science & Forestry Syracuse, NY Architerra According to the AIA: “The SUNY-ESF College of Environmental Science & Forestry Gateway Center is a striking symbol of environmental stewardship and climate action leadership. This LEED Platinum campus center meets ESF’s goal of reducing the overall carbon footprint of the campus through net positive renewable energy production, while creating a combined heat and power plant and intensive green roof that serve as hands-on teaching and research tools. The double-ended bioclimatic form exemplifies passive solar design. Net positive energy systems integrated with the design serve four adjacent ESF buildings, providing 60% of annual campus heating needs and 20% of annual power needs.” John & Frances Angelos Law Center Baltimore, Maryland Behnisch Architekten and Ayers Saint Gross According to the AIA: “The John and Frances Angelos Law Center is the first large-scale opportunity for the University of Baltimore to demonstrate its intent to pursue strategies that eliminate global warming emissions and achieve climate neutrality. With this in mind, the Law Center is a highly sustainable and innovative structure that strives to reduce reliance on energy and natural resources, minimizing its dependence on mechanical ventilation and artificial lighting of interiors. This is part of a larger comprehensive effort on the part of the A/E team to approach sustainability from a more holistic vantage point from the outset of the project.” Sustainability Treehouse Glen Jean, West Virginia Design Architect: Mithun; Executive Architect/Architect of Record: BNIM According to the AIA: “Situated in the forest at the Summit Bechtel Reserve, this interactive, interpretive and gathering facility serves as a unique icon of scouting adventure, environmental stewardship and high performance building design. Visitors ascend indoor and outdoor platforms to experience the forest from multiple vantages and engage with educational exhibits that explore the site and ecosystem at the levels of ground, tree canopy and sky. Innovative green building systems—including a 6,450-watt photovoltaic array output, two 4,000-watt wind turbines, and a 1,000-gallon cistern and water cleansing system—combine to yield a net-zero energy and net-zero water facility that touches its site lightly.” The David and Lucile Packard Foundation Headquarters Los Altos, California EHDD According to the AIA: “The David and Lucile Packard Foundation headquarters acts as a catalyst for broad organizational sustainability and brings staff, grantees and partners together to solve the world’s most intractable problems. The Foundation's connection to the Los Altos community dates back to its inception in 1964. For the last two decades, as its grant making programs expanded locally and worldwide, staff and operations have been scattered in buildings throughout the city. This project enhances proximity and collaboration while renewing the Foundation’s commitment to the local community by investing in a downtown project intended to last through the end of 21st century.” U.S. Land Port of Entry Warroad, Minnesota Snow Kreilich Architects According to the AIA: “This LEED Gold certified Land Port of Entry is the first to employ a ground source heat pump system. Sustainably harvested cedar was used on the entire exterior envelope, canopies and some interior walls and 98% of all wood on the project is FSC certified. Additionally 22% of the material content came from recycled materials and 91% of all work areas have access to daylight. Rainwater collection, reconstructed wetlands and native plantings address resource and site-specific responses. The facility proudly supports the mission-driven demands of US Customs and Border Protection while addressing the sustainable challenges of our future.” Wayne N. Aspinall Federal Building and U.S. Courthouse Grand Junction, Colorado Design Architect, Westlake Reed Leskosky and Architect of Record, The Beck Group According to the AIA: “The LEED® Platinum renovation preserves an anchor in Grand Junction, and converts the 1918 landmark into one of the most energy efficient, sustainable historic buildings in the country. The design aims to be GSA’s first Site Net-Zero Energy facility on the National Register. Exemplifying sustainable preservation, it restores and showcases historic volumes and finishes, while sensitively incorporating innovative systems and drastically reducing energy consumption. Features include a roof canopy-mounted 123 kW photovoltaic array, variable-refrigerant flow heating and cooling systems, 32-well passive Geo-Exchange system, a thermally upgraded enclosure, energy recovery, wireless controls, fluorescent and LED lighting, and post-occupancy monitoring.”
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.
We just wrapped up the latest installment of our Facades+ conference series. It was our most successful event yet! The response was overwhelmingly positive as hundreds of eager professionals converged on Chicago to discuss the most exciting breakthroughs in facade technologies. With sold-out workshops, standing-room-only panels, and sponsors already signing up for next year, Facades+ PERFORMANCE surpassed our greatest expectations! "The Facades+ conference hits the sweet spot between design, engineering, the industry, and the academy, so there's really something for everyone," said AN executive editor Alan G. Brake. "The Chicago conference, at the beautiful IIT campus ablaze with fall color, was one of the most successful to date. It was two days full of inspiring, behind the scenes stories of how great buildings are made and the important technical knowledge that is advancing the profession.” Facades+ PERFORMANCE, presented by AN and Enclos, marked the sixth event in our expanding legacy of conferences. Focusing on the most pressing issues in design, construction, and fabrication of cutting-edge facades, Facades+ has traversed the nation to bring critical dialogs on the building skin to the innovative processionals at the heart of the AEC industry. This year, the crowds went wild as keynote speakers Stefan Behnisch (Behnisch Architekten) and Gerardo Salinas (Rojkind Arquitectos) discussed the rapidly evolving role of the building skin amidst emerging technologies, and the architects’ struggle to maintain sustainability while making the most of these radical innovations.

Be there as German architect Stefan Behnisch, founding partner of Behnisch Architekten, delivers his featured keynote address on the shifting role of the building skin in the wake of emerging technologies. Network with fellow professionals and join in the dialog with representatives from SOM, Gehry Technologies, Morphosis, SHoP, Thornton Tomasetti, and other industry-leading firms. From cocktails in Rem Koolhaas–designed IIT McCormick Tribune Campus Center, to hands-on workshops in the latest design technologies and intimate discussions of some of today's most exciting projects, this is one event you cannot afford to miss. Register today to join the revolution that is changing the face of our built environment. “With the challenges we face in the built environment, facades are becoming more and more an integral element of architectural design and engineering,” said Behnisch in a statement. “It is not only the visual appearance but also the performance of a building that depend on the facade.” With dozens of completed projects across Europe and the United States, Behnisch has made a name for himself through the dynamic forms, state-of-the-art facades, and the socially and environmentally sustainable focus of his work. As our featured keynote speaker, Behnisch will draw from his professional experience discuss the evolving functions of facades and the architect’s role within this changing landscape. “In the search for a more sustainable built environment, we, the architects have to assess the conditions under which our buildings have to be built and the conditions under which they have to perform. Whilst in the second half of the 20th century, the International Style allowed us to build similar buildings within many different climates, we cannot afford to do this anymore. …Today, we have to analyze the climatic, the cultural, the geopolitical, the social, the geographical and the topographical conditions of our potential buildings.” The seats are filling up fast, so reserve your space today to hear more from Behnisch and the rest of the exciting lineup of presenters at Facades+ PERFORMANCE!
