On 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.

On June 7th, 2018, The Architect’s Newspaper will once again bring the Facades+AM conference to San Francisco. AN has put together a stellar lineup of speakers and presenters for the day-long event that promises to give a granular view of some of the most exciting developing technologies in the realm of high-performance facade design that have emerged in recent years, as building integration, resilient buildings, and sustainable design have taken a deeper hold in the architecture, engineering, and construction industry.
The day’s program will be opened with a welcome by Emilie Hagen, associate director of Atelier Ten. Hagen helps lead Atelier Ten’s San Francisco team and is a member of the Facade Tectonics Steering Committee. Atelier Ten is currently at work on a slew of high-tech, globally-significant projects, including the forthcoming Google headquarters in London with BIG and Thomas Heatherwick, and has previously worked on the San Francisco Museum of Modern Art expansion with Snøhetta.
The opening remarks will be followed by a panel discussion titled “Beyond Little Boxes: Innovations in Facade Design and Delivery” that will focus on the radical transformations occurring within the Bay Area’s building stock, as the city densifies and builds out new residential, medical, and college campuses. The panel will feature Stanley Saitowitz, principal of Natoma Architects; Shruti Kasarekar, associate at Atelier Ten; and Mark Cavagnero, founding partner of Mark Cavagnero Associates.
That discussion will be followed by a deep dive into the design of SHoP’s new headquarters in San Francisco’s Mission Bay for carshare company Uber. The 423,000-square-foot project, focused around the delivery of an iconic and operable façade, will include an 11-story tower as well as a shaded patio overlooked by operable walls, among other components. AN has organized a panel featuring Alex Cox, development manager at Permasteelisato; Karen Brandt, senior principal at Heintges; Ryan Donaghy, senior associate at SHoP; Sameer Kumar, director of enclosure at SHoP; and Thilo Wilhelmsen, tender leader at Josef Gartner, to discuss how the design team has redefined conventional facade performance characteristics for the project.
Next, the conference will delve into some of the Bay Area’s newest premier projects—like the Pelli Clarke Pelli Architects-designed Salesforce Tower and Transbay Terminal and the Manica Architecture-designed Golden State Warriors Arena—in a panel titled “Signature San Francisco: Delivering the Bay Area’s Next Generation of Facades.” The discussion will include Mirjam Link, senior project manager at Boston Properties; Sanjeev Tankha, director at Walter P Moore; and Daniel J. Dupuis, principal at Kendall Heaton.
The conference will also include a pair of “extra credit” lunch-and-learn presentations focused on perimeter fire barrier systems and on laminated glass railing design led by industry leaders STI Firestop and Trosifol.

This soon-to-be neighbor of Grand Central Terminal was strongly influenced by its Midtown context. “From very early on, even the competition phase, we felt really strongly that it needed to have an element of masonry construction,” said Darina Zlateva, associate principal at Kohn Pedersen Fox (KPF). “Obviously, this is a high-rise super tall building, and so how that translated to us was high-performance terra-cotta, which we included in our spandrel.”

The team chose to collaborate with Boston Valley Terracotta, and the two companies have been working on the glaze since 2013. Terra-cotta is included throughout the entire tower—including the podium—and there is a series of cuts at the base whose underside is entirely made up of terra-cotta. The spandrel zone has diagonal pieces of white terra-cotta that extend from the base to the very top of the tower. The curtain wall is double-glazed, double-fired terra-cotta, the structural system is extruded aluminum, and there is a high-performance glass on the vision—it’s an IGU with a Low-E coating on the number two surface, provided by Guardian. The gold metal fenestration that doubles up as a shading device is composed of back painted glass with a metallic finish, supplied by Permasteelisa.
The building partition is four interlocking sloped masses, which provide air and light down to the street. “This is something that’s really important for the city of New York,” stated Zlateva, “so we worked with the Department of City Planning to make sure that our building angles complied with their light and air requirements.” At the base, those four tapered volumes get sliced in order to create a view corridor to Grand Central. This will mark the first time in a century that pedestrians will be able to see the corner of the terminal from 42nd Street.
Solarban 90 glass uses a proprietary coating technology that offers exceptional solar control as well as high-visible light transmittance. The low-E glass is now available in a large assortment of tints, including blue, bronze, gray, and green.
A moisture-free, sustainable closed-cavity facade system that is cost-efficient and designed so that no dust or condensation can permeate the internal cavity of its double skin. This system can be integrated with automated solar-shading systems as well.
This velvety finish can be used in both vision and spandrel applications, and offers a translucent appearance. SatinDeco can be combined with many of Guardian’s SunGuard products and allows for maximum daylighting while offering privacy.
The new hurricane-resistant curtain wall from CRL-U.S. Aluminum offers protection against severe weather, is NFRC-rated, and has Florida product approval. This improved system uses a continuous thermal space and offers a shear block assembly with no exposed fasteners for a clean aesthetic and easy installation. Additionally, it is glazed with 1-5/16-inch insulating laminated glass.
An innovative new offering from Pulp Studio, this glass is made of a crystalline silicon structure that makes it as hard as granite, but more consistent than natural stone. Unlike stone, it can be bent, formed, carved, and specified in particular thicknesses that can reduce cost and waste. And, because it contains no resins, Stoneglass can be recycled.
The new line of FI, TU, and XT models allow for taller and wider storefronts, including spans as high as 14 feet. These storefronts offer a cost- and energy-efficient alternative to curtain walls for use in retail and low-rise offices.
A research center in Manhattan gets a custom facade solution for energy efficiency and user comfort.
Ennead Architects and Heintges & Associates recently completed construction on the 475,000-square-foot Belfer Research Center, Weill Cornell Medical College’s latest expansion to Manhattan’s Upper East Side. The building’s facade includes a unique double skin system on the southern face to define the medical campus’ identity, provide ample natural light without glare to the laboratory spaces, and create a highly efficient envelope.
Heintges and Ennead previously worked together on the neighboring Weill Greenberg Center in 2007, said Todd Schliemann, partner in Ennead Architects and designer of both WCMC’s Weill Greenberg Center and new Belfer Research Building. Among the strategies employed in that project was the use of custom ceramic fritting to cut down on sun loading and glare. The team repeated that strategy at Belfer, applying ceramic frit to both sides of the building’s outer curtain wall. The exterior of the outermost layer features a white frit pattern designed to reflect sunlight, while a black frit pattern on the interior surface helps reduce glare and increase visibility through the glass.

System double insulated dual glass curtain wall with ceramic frit
The double curtain wall produces a chimney effect that reduces cooling loads. For insulation, the inner layer is composed of argon-filled insulated glass units. “We conducted a lot of thermal analysis to minimize bridging through the outriggers,” said John Pachuta, a partner at Heintges. The framing system for the inner wall is thermally broken; a layer of mineral-fiber insulation behind the frame helps improve performance. Permasteelisa manufactured the 5-foot units in its Montreal facility. Glass from BGT was treated with an Interpane coating, and outrigger connections were affixed to the frame every 5 feet. The outriggers also extend to support the outer skin.
For the outer wall, unitizing the unique geometries helped maintain the building schedule, despite its complex appearance. “We learned that even with a subtle shift in plane, you can still use standard parts and pieces,” said Schliemann. The team was able to reduce the number of IGUs and achieve a more monolithic appearance by using larger, 10-and-a-half-foot panels, ultimately requiring fewer joints. The grid breaks into 21-foot repetitions, in order to accommodate window washing balconies that also provide faceted cavities in the exterior curtain wall. The cavity between the two skins measures between 18 and 25 inches to accommodate an aluminum catwalk, which is supported by the inner wall’s outriggers. Access points to the catwalk can be reached from the interior for cleaning and maintenance.
With increasingly erratic environmental conditions in the Northeast corridor, the entire system had to be secure yet resilient. “We considered having support members starting from the base building structure—from the perimeter beams or columns to extend through the inner curtain wall—but to reduce thermal bridging it was more effective to have outriggers extend through the weather enclosure,” said Pachuta. “Instead, steel outriggers support the catwalk and outer screen wall that are directly attached to the mullions of the inner curtain wall.” Mullions of the inner curtain wall are reinforced with steel, and are anchored to the outer wall at the edge of each unit.
The faceted cavities produce good ventilation, but also leave the protected areas open for pigeons to nest. En lieu of standard bird wire, the team developed a custom steel frame with tensioned, horizontal stainless steel rods ¾ inches apart. Though the system keeps the sky rats at bay, the wire is no wider than a bicycle spoke and does not impede views from inside.
