SOM's Tianjin CTF Finance Centre meets the breeze with a biomorphic form

Brought to you with support from
For what will be the eighth-tallest building in the world when finished in Tianjin, China, later this year, SOM didn’t want to do a by-the-numbers glass facade. Which is good, because the designers couldn’t have even if they wanted to—the Tianjin CTF Finance Centre’s convex and concave surfaces, along with its tapered shape, meant to help shed the wind loads bearing on such a tall building (it will eventually reach over 1,700 feet), demanded an original solution.

The building’s biomorphic form, reminiscent of the pistil of a hothouse flower, suggests it could have used curved glass panels, but it doesn’t—the client wanted something less risky. The architects instead chose flat glass panels—about 11,500 total—from China Southern Glass (CSG Holding Limited). The vision glass comprises Insulated Glass Units with heat-strengthened, laminated, low-iron outer lites, a double-silver, low-e coating, and tempered, low-iron inner lites. Spandrel panels are made of low-iron laminated glass. The use of flat glass panels meant that the designers had to get a bit more creative with the mullions to cover the doubly curved surfaces. They turned to an adaptable mullion system from Jangho, a major Chinese curtain-wall manufacturer, that could take over some of the formal gymnastics. In total, only 476 unique glass panel types were needed. The design team also wanted to find a way to minimize the window-to-wall ratio to reduce solar gain and increase insulative value while still providing ample daylight. They ended up with V-shaped mullions that are almost 11 inches wide on the exterior and narrow to a much smaller profile on the interior. The building’s taper gave each floor a different shape; therefore, the exterior panels fit differently around every level, which meant that the mullions couldn’t easily be arranged in perfectly continuous lines up the building. Rather than trying to approximate vertical stripes with the mullions, the designers staggered them to create a snakeskin-like effect that reads as organized but organic, a reflection of the flexible thinking required to erect this giant.

Facades+ Toronto will dive into the trends of North America's fastest growing construction market

facadeplus_logo1
Brought to you with support from
On October 11, The Architect's Newspaper is bringing Facades+ to Toronto for the first time to discuss the architectural trends and technology reshaping the city and region. Toronto's KPMB Architects, an architectural practice with a global reach, is co-chairing the conference. Panels for the morning symposium will discuss KPMB Architects' decades-long collaboration with Transsolar Klima Engineering, the proliferation of timber construction across Canada and specifically its university campuses, and the adaptive reuse of Ontario's architectural heritage. The second portion of the conference, which occurs in the afternoon, will extend the dialogue with intensive workshops. Participants for the conference symposium and workshops include the Canada Green Building Council, the Carpenters' District Council of Ontario, the College of Carpenters, Diamond Schmitt Architects, ERA Architects, Kirkor Architects & Planners, Maffeis Engineering, Moses Structural Engineers, MJMA, NADAAA, RDH, and UL. In this interview with The Architect's Newspaper, KPMB's Director of Innovation Geoffrey Turnbull and Senior Associate David Constable, the conference co-chairs, discuss the theme of the symposium's first panel, "Dynamic Skins: A Conversation on Innovative Facades," an exploration of KPMB and Transsolar's use of double-glass facades. AN: KPMB & Transsolar’s collaboration began over a decade ago with the Manitoba Hydro Palace. Can you expand on the significance of the project, and how lessons learned from the collaboration were applied to future projects David Constable & Geoffrey Turnbull: Manitoba Hydro represented a turning point for KPMB in how the office approached sustainability, but more fundamentally, forced a re-think of the typical design process. This project demonstrated how building design and function may converge to become something greater than a sum of its parts. One of the first projects in North America to invest in a true IDP, or ‘Integrated Design Process’, the design team undertook a process with the client to bring all disciplines to the table at the very beginning of the project. Decisions were discussed and evaluated in detail with input from all disciplines, and the form and strategy for the project grew organically from that process. The first step in the integrated process was the development of a Project Charter, which became the guiding code against which all decisions were measured and validated. AN: How does the use of software inform Transsolar’s consulting during the design process? DC & GT: Transsolar has a high degree of in-house technical expertise in the physical sciences, as well as a deep well of experience on built projects. These capabilities, paired with advanced modeling tools, gives Transsolar a unique ability to develop strategies for projects from a first-principles perspective. As architects, this is transformative in terms of the possibilities that can arise from a collaboration with Transsolar. Where we would otherwise be limited to rules-of-thumb and best practices, working with Transsolar allows us to interrogate the particulars of a given project and derive solutions that are unique to that specific project. Manitoba Hydro Place is an excellent example of this… It’s not immediately obvious that, in a cold climate like Winnipeg, a glass office tower would make sense. By understanding the site, identifying what is unique about it (e.g. there is a very high degree of sunshine in Winnipeg for such a cold city), and then building a strategy around that, we were able to design a project that provides an exceptional degree of comfort for the occupants, a lot of natural daylight, and terrific views to the landscape, all while being one of the most energy-efficient buildings on the continent in a city with a seasonal temperature swing of 65 degrees. In addition, Transsolar uses Transys modeling software, which allows for robust, iterative testing of concepts at a small scale, allowing the team to quickly test assumptions and prove out specific relationships between building components. This process allows active components such as motorized operable windows and automated louver blind systems to be tested in a dynamic way. Elements such as wind, sun, and humidity can all be modeled and reviewed dynamically over the course of an entire year. AN: All of the projects to be discussed during "Dynamic Skins" possess double-glass facades. Can you elaborate on this feature and its merits? DC & GT: Ultimately, on any project where a double facade represents an optimal solution, this will be driven primarily by the desire to optimize the interior environment for occupants. These systems allow us to accomplish a host of optimizations that enhance comfort in the space: maximize daylighting while modulating glare, provide natural ventilation for a larger percentage of the year, minimize radiant asymmetries so that it’s comfortable to sit near the window in winter and summer, etc. Fundamentally the difference between a traditional facade and a double facade is this concept of static versus dynamic. Traditional facades are forced to implement one static condition throughout the entire course of the year. In a Canadian environment, this can represent a huge swing in conditions – temperature, radiance, wind, and humidity can all change radically and quickly. A double facade allows the building skin to become an active component in the life of a building. Windows and shading devices become active elements which remain in constant dialogue with both the interior and exterior environment and allow the building to adapt in real-time to its environment.

Krueck + Sexton and Thornton Tomasetti bring undulating glass to Chicago's Mercantile Exchange

facadeplus_logo1
Brought to you with support from
Chicago's Krueck + Sexton Architects, a practice founded in 1979, has established a particular niche in the design and implementation of complex glass facades. Their projects present a significant range in terms of location and scale, ranging from the multiplanar Spertus Institute on Michigan Boulevard to a slew of private residences and the restoration of Mies van der Rohe's prestigious structures dotted throughout Chicagoland. Recently, the firm wrapped up a full revamp of the Chicago Mercantile Exchange's lobby with an undulating structural glass wall. Located on Lake Michigan, Chicago has served as country's primary inland entrepot for over a century—the Chicago Mercantile Exchange (CME) was founded in 1898. The CME migrated to its current headquarters in 1987, a heavy granite-clad postmodern tower located immediately adjacent to the Chicago River. The design objective of the project was to establish an inviting and prominent facade for a structure in which over 10,000 people cross through daily, replacing 18 separate dark and weighty entrances.

The glass streetwall runs the entire width of the city block, weaving behind the square columns that form an encircling arcade. When developing the overall contour of the glass facade, Krueck + Sexton Architects analyzed the movement of surrounding pedestrians and inputted that information to follow the preexisting desire lines of foot traffic. Roschmann Group, the Germany-based manufacturer, handled the fabrication of the bespoke system. Each panel measures approximately 25-feet-by-four-feet and were installed using a custom-designed suction cup lifting device. "The glass is base loaded, and the glass fins provide support for lateral loads such as wind and inside and outside differential," said Krueck + Sexton Associate Principal Yugene Cha. "The top of the glass fin is held by a clever suspension system that can slide up and down and sideways allowing the building to move without breaking the glass." The street-level prominence of the facade, as well as the remarkable visibility of the oversized glass panels, required the implementation of direct and simple detailing where pane meets the ceiling, ground floor, and glass fin. The most challenging aspect of almost any project is the unforeseen conditions onsite after the commencement of construction. For the CME, frequent shifts in the grade below the street level required recalibrations of waterproofing details as well as glazing base plate design. It was critical to the success of the project to loop in the facade engineer, Thornton Tomasetti, from the point of conception. "First, Krueck + Sexton and Thornton Tomasetti worked together to develop a highly-detailed and complete facade package in the Schematic Design Phase, setting the project up for a successful Bidding Phase and Design Assist collaboration," said Thornton Tomasetti Senior Project Director Mark Chiu. "Second, Thornton Tomasetti pre-engineered the facade system’s glass sizes and thicknesses shown in the Schematic Design documents, validating the minimalist design details." Behind the structural glass facade, Krueck + Sexton placed a sophisticated system of 2,644 white synthetic-mineral panels that rise and curve to form the ceiling and continue outward to roof the arcade. The material is non-porous, allowing for straightforward maintenance. Krueck + Sexton Architects Founding Principal Mark P. Sexton and Thorton Tomasetti Senior Project Director Mark Chiu will be joining the panel "Ongoing Advancements in Glass Technology: From Smart Coatings to Connection Design" at the Architect's Newspaper's upcoming Facades+ Chicago conference on September 12. In the afternoon, the panel will be extended into an intensive three-hour workshop.

Pei Cobb Freed's One Dalton joins the Boston skyline with curved glass curtainwall

facadeplus_logo1
Brought to you with support from
Rising from a triangular lot in Boston’s Back Bay, One Dalton is a 61-story, 706,000-square-foot residential tower designed by Pei Cobb Freed & Partners. Its gently curving triangular floorplan—a direct product of the unique site—is extruded vertically to create the building’s clean but dynamic glass form. The slightly bulging facades and the sheer size of the glass units presented some major challenges when it came to developing the cladding. The glass panels are some of the largest the firm had ever worked with, with a typical unit spanning 12-feet-tall by almost 6-feet-wide with a 30-degree curve. The firm set ambitious goals for the glass beyond the unusual size and shape with specific targets for deflection and distortion, solar and thermal transmission, color rendering, transparency, UV filtration, glare and reflectance, and noise suppression.

To find the perfect glass, the architects tested many different assemblies using full- scale mock-ups. They ultimately decided on a hybrid design that incorporated laminated, tinted glass with a mild, Low-E coated solar control product (Guardian SunGuard SN 70/41), a low-iron substrate, and argon-filled airspace. Testing also showed that the curving glass produced funhouse mirror-like reflections at night, so an interior anti-reflective coating was added as well. Much like the individual panes of glass, the overall facade is more complicated than it at first appears. Subtle incisions break up the massing of the upper 40 floors, creating protected spaces for operable casements while formally suggesting large bay windows that distinguish the condominium units from the hotel rooms below. “I’m a great believer that, especially in a city, it’s important to bring out the different uses that are taking place [in a tower],” Henry Cobb told the audience in June at AN’s Facades+ conference in Boston. One Dalton wouldn’t be possible without the rapid evolution of architectural glass driven by ambitious designs and new technologies. Commenting on these changes, Roy Barris, associate partner at Pei Cobb Freed, noted that despite the firm’s exhaustive pursuit of the perfect material, “If we were to start this project again today, we’d have to start from scratch.”

Brooks + Scarpa parts the veil with an undulating brick screen wall

facadeplus_logo1
Brought to you with support from
Evanston, Illinois is located over a dozen miles from the city center of Chicago, on the northern fringe of Cook County, and is bounded by Lake Michigan to the east. The city is fairly typical for the region: there is a postwar central business district surrounded by tracts of suburban housing, some clad with wood drop-siding and others with exposed brick. Completed in 2018, the Lipton Thayer Brick House by Los Angeles-and-Florida-based architectural practice Brooks + Scarpa and Chicago's Studio Dwell burst onto the scene with a twisting-brick screen backed by a Miesian glass curtain wall. The 2,500-square-foot family residence and conforms to the city-mandated suburban lot lines, with the entire outer shell composed of Chicago Common Brick. The side elevations rise sheer with limited fenestration to the east and west, while the 21-foot-tall brick skin on the north elevation breaks to partially reveal the entrance courtyard.

  • Products Chicago Common Brick Vitro Solarban 80 LM Scolfeild Lithochrome
As Chicago Common brick has not been produced for nearly four decades, the material was salvaged from past and ongoing demolitions of historic structures. It is an irregular and coarse material formerly harvested from local clay beds that were formed from the diverse deposits of retreating glaciers from the last ice age. The resulting finish—the clay is baked at a temperature of 1500-degrees Fahrenheit over the course of a few days— is inconsistent in color from brick to brick which provides a softly gradated facade. While visually complex, the design team utilized a straightforward methodology to achieve the rotating pattern. "Using ruled surface geometry, the undulating facade is formed by connecting two curves with a series of straight lines to form the surface of the facade," said Brooks + Scarpa. "This technique allowed the design team to work with complex curved forms and rationalize them into simple, cost-effective standardized components, making them easy to fabricate and efficient to install." A thin layer of mortar is located between each successive brick of the vertical columns. However, the task of keeping the masonry screen in place falls to a steel system produced by Accurate Metal Chicago. A steel rebar pipe, running from base to cornice, passes through each individual brick. Additionally, interstitially-placed steel plates are integrated with the vertical bands of rebar and brick every few courses, supplementing the screen with horizontal bracing. Past the screen wall, the courtyard is lined with rectangular, high-visibility glass curtain wall modules framed with aluminum. Sunlight from the northern exposure is filtered through the screen wall, softening the daylight that reaches the interior spaces. The rear elevation, which faces a service alley, is composed of recycled Portland cement panels stained with LITHOCHROME to achieve a light-grey finish.

ODA's 10 Jay Street in DUMBO shines with a faceted facade

facadeplus_logo1
Brought to you with support from
Over the last two decades, Brooklyn's DUMBO neighborhood has undergone a significant degree of development, including the restoration of historic warehouses that dominated the neighborhood for centuries and plenty of new construction. ODA, which has a number of projects across the borough, recently completed the restoration and partial recladding of a decrepit 19th-century refinery and warehouse with a lively, iridescent glass curtainwall. The 130,000-square-foot development, which reaches a height of 10 stories, was originally built in 1898 as a sugar refinery for the Arbuckle Brothers and relied on a steel structural system with the brick elevations largely serving as curtainwall. Similar to other structures throughout the neighborhood, the building has undergone significant changes since construction; in 1925 it was converted to a winery, with the west elevation shorn off a decade later. The site was left vacant and in a state of continual decline from the middle of the 20th century until 1991.

The design from ODA draws from this history with a crystalline western elevation which shimmers and reflects the skyline of Lower Manhattan and the East River. According to ODA communications director Juan Roque Urrutia, "besides the construction challenges of dealing with an old structure, one of the main challenges was to actually convince the Landmarks Preservation Commission about the values of the original building and how a modern incorporation of a kaleidoscopic facade was not only respectful but also appeals to heritage stories." The glass modules are split between rectangular and triangular units, which rise perpendicular to the floor plate or inflect inward to effectively create concave bay windows. Minor segments of brick are interspersed throughout the western elevation and are located adjacent to the branch-like mullions. The average dimensions of the glass modules are approximately 11-by-5 feet, and each module was treated with a low-e coating to boost their reflectivity. Each panel spans from floor-to-floor and is held to the top of each floor slab with an aluminum anchor plate and hook. Grafting an entirely new skin onto a historic structure is a remarkably complex procedure, and ODA turned to facade consultant SURFACE DESIGN GROUP (SDG), who have established a particular expertise in facade retrofit and historic preservation. The retrofit uses a unitized glass and aluminum curtain wall system with angular facets and spandrel panels located at the slab edge. "As part of the north façade retrofit, the existing historic brick and terra cotta arched floors were extended with reinforced concrete to meet the new profile of the faceted facade," said the SDG team. "Given the complexity of both the curtain wall panel and edge of slab geometry, which is also faceted to mirror the form of the panels, standardizing the anchoring method aided in the efficiency of panel installation." Standing derelict for decades, the former sugar refinery also required an extensive degree of restorative work. First, stucco coating from the 1990s, and layers of old paint which hastened the decay of the brick masonry, had to be peeled away. The east elevation suffered the worst of the building's deterioration and required the complete reconstruction of the brick facade and the underlying steel structure. The remainder of the restorative work entailed brick replacement—nearly a third of them recycled, steel spandrel repairs, mortar repointing, and the application of a new weather resistant coating. The project is located in the DUMBO Historic District and required the input and approval of the Landmarks Preservation Commission throughout the design and construction process.

RIBA sustainability chairman urges London to consider a glass tower ban

Following NYC Mayor Bill de Blasio’s "ban" on glass-clad buildings in April, a leading sustainability expert in London has spoken out against London mayor Sadiq Khan’s refusal to enact the same legislation—Simon Sturgis, an adviser to the Greater London Authority and a chairman of the Royal Institute of British Architects' (RIBA) sustainability group, believes that England's capital should follow suit. While de Blasio’s "ban" was in actuality proposed as a check on excessive use of glass and steel, glass is an inherently problematic building material to use in a world facing a climate crisis and rampant carbon emissions. Sturgis told the Guardian that, “If you’re building a greenhouse in a climate emergency, it’s a pretty odd thing to do, to say the least.” The two cities of New York and London are home to iconic skyscrapers like The Shard and the World Trade Center, both considered pinnacles of glass and steel construction, but while their uninterrupted views and the striking skyline aesthetic attract architects and high-profile tenants at the moment, the environmental irresponsibility may soon phase the desirability out.  “Big commercial tenants don’t like standing up in front of their shareholders and saying they’re doing embarrassing things,” said Sturgis. Glass facades have a short life span, only about 40 years, so the impact of their embedded carbon (how much carbon a product will emit over the course of its entire life) is significant, as a building's glazing is nearly impossible to recycle and inevitably necessary to replace. However, the more immediate consequences of these glass facades is a heavy need for air conditioning. The amenity's adverse environmental impacts are well documented—almost 14 percent of total global energy use stems from air conditioning, and the heat captured and retained in building interiors by glass curtain walls is significant, especially in the summer heat.  In the same article, head of sustainability at Mitsubishi Electric, Martin Fahey, stated that rising temperatures across the globe has led to AC equipment needing to work much harder than in the recent past. “Most air conditioning equipment is designed to give an internal temperature between seven-to-ten degrees lower than the ambient temperature,” he said. But when the recent heat waves struck London and New York this summer, cooling from 100 degrees Fahrenheit to a more comfortable 70 took a toll on local electrical grids as well the air conditioners themselves. Broken AC units and their subsequent replacements add to the embedded carbon footprint of our built structures.  Advanced glazing and passive cooling options exist today that can minimize the greenhouse effect of glass, like darkening to let in less light in the warmer months, for example, the double- or triple- glazing systems are still hindered by the short life span and non-recyclability, and often not nearly at the level needed to amend the footprints of commercial emitters. Sturgis warns that “the connection needs to be made between the climate emergency and all-glass buildings. But the connection hasn’t been made yet.”

The project was inspired by the capacity for cinema to transport viewers to a new world, and the architects think of the 45,000-square- foot sphere as a spaceship. More specifically perhaps, the project evokes the TARDIS—Doctor Who’s time-and-space-traveling police box that’s famously bigger on the inside than appears possible from the outside. As Mark Carroll, partner at RPBW notes, “We didn’t want it too large, because it could overpower the Saban Building. So we tried to keep it small and compact but still big on the inside.” The sphere’s two primary programs drove its design: the spacious 1,000-seat David Geffen Theater and the Dolby Family Terrace. The majority of this cinematic starship is clad with 680 precast-concrete panels attached to a shotcrete structural frame. The concrete is the visible part of a “box in a box” assembly that was designed to acoustically insulate the theater from within and from without. Behind the precast shell, a floating gypsum box completely encloses the space to provide additional soundproofing. Atop the sphere, a glass dome covers the Dolby terrace, which offers expansive views toward Hollywood to the north. The dome comprises exactly 1,500 overlapping low-iron glass shingles set over a graceful steel frame—a solution arrived at after “many interactions,” according to Carroll. Among the 146 unique shapes of shingles are glass vents, arranged at the top of the dome to help keep the open-air terrace cool. To ensure the structure stays rigid during a seismic event, cables crisscross the frame’s 4-inch structural supports, which span 120 feet across the roof and over the dome, casting dynamic shadows onto the curving facade. RPBW carefully coordinated the construction of the glass and concrete elements, which were cast with openings to attach the dome’s “egg cutter” structure. The project is the latest blockbuster building on L.A.’s Miracle Mile, joining a collection that includes RPBW’s additions to the Los Angeles County Museum of Art. The futuristic dome is not only an apt addition to the neighborhood but to the original structure, whose Streamline Moderne design offers an optimistic vision of the future from another era. As Piano said, “The Academy Museum gives us the opportunity to honor the past while creating a building for the future—in fact, for the possibility of many futures.”

New Glass Now paints a full picture of contemporary practice at the Corning Museum of Glass

Capturing the zeitgeist of contemporary glass practice, the New Glass Now exhibition at the Corning Museum of Glass brings together work from 100 emerging and established talents across 32 nationalities. Exhibited pieces, ranging from large scale installations to delicate miniatures, were democratically selected based on an open call submissions process by a curatorial committee comprised of leading culture-makers and experts Aric Chen (Design Miami Curatorial Director), Susanne Jøker Johnsen (artist and head of exhibitions at the Royal Danish Academy of Fine Arts, Schools of Architecture, Design and Conservation, Denmark), and Beth Lipman (American artist). Susie J. Silbert (Corning Museum of Glass Curator of Modern and Contemporary Glass) headed up the jury and exhibition curation. Addressing relevant themes such as gender inequity and environmental degradation, the highly-curated exhibition reveals what glass can achieve through various expressive and conceptual interpretations, as well as new translations of age-old techniques like flameworking, glassblowing, and casting. Exhibition sections :in situ, :(infra)structures, :body politics, :embodied knowledge, :011001111 01101100 01110011, and :phenomena incorporate works that transcend disciplinary conventions. On view are sculptures, functional objects, photographs, videos, technological speculations, scientific experiments, architectural maquettes, and full-scale mockups. Through various strategic stagings, Silbert sought to establish sharp dialogues between different, seemingly unrelated, works. Fredrik Nielsen's "macho" I was here installation sits in the direct vicinity of Deborah Czeresko's emphatically feminist Meat Chandelier sculpture, a piece very similar to the final work she created during the Corning Museum of Glass-supported Netflix competition series Blown Away Pieces such as Liquid Sunshine / I am a Pluviophile by Japanese artist Rui Sasaki reveals how glass can be implemented in expressing conceptual meaning, while Smokey Comet Installation I by Toots Zynsky challenges the perception of what the medium can physically achieve. The Bahá'í Temple of South America project by Jeff Goodman, and Crystal Houses (Chanel Flagship Store) by MVRDV showcase glass's potential in an architectural application. Reservoir by C. Matthew Szösz and Promise by Nadège Desgenétez demonstrate how far the material properties of glass can be pushed. Other notable artists, designers, and outright creatives represented in this comprehensive survey include Miya Ando, Atelier NL, Ans Bakker, the Bouroullec Brothers, Monica Bonvicini, Mathew Day Perez, Martino Gamper, Katherine Gray, Jochen Holz, Helen Le, Erwin Wurm, Dustin Yellin, Dafna Kaffeman, Bohyun Yoon, and Mark Zirpel. The main show is joined by New Glass Now | Context, an annex exhibit that explores the changing nature of glass-specific curation through the history of two past iterations of the New Glass exhibition series, in 1959 and 1979. Historic documentation, period-specific works, and related ephemera are displayed in the Corning Museum of Glass's Rakow Research Library and collectively reveal some clear differences in terms of method and focus but also socio-political and cultural influences.

Brought to you with support from
Positioned adjacent to Lake Geneva and the Parc Louis Borget, the Olympic House is located on the outskirts of Lausanne, Switzerland. Opened in June 2019, the objective of the building's scheme was to bring the International Olympic Committee's hundreds of employees, spread across the city, under one roof. The project—which began as a competition in 2012—was led by the Danish architectural practice 3XN in collaboration with Swiss firm Itten+Brechbühl. For the facade of the new headquarters, the design team developed an undulating double-skin glass facade crafted with a custom-parametric script that produced thousands of models and drawings.

The building rises to a height of four stories and encompasses nearly 240,000 square feet, with the lowest floor burrowed into the landscaping. According to the design team, the primary stylistic influence for the enclosure was the form of the athlete—each perspective provides a different viewpoint of the building, as if it were in movement. To develop the form of the Olympic House, 3XN relied on a minimal data model defined by five parametric curves per elevation. A separate drawing was developed for each component of the facade assembly, culminating in approximately 33,500 individual drawings. The original design concept developed by 3XN called for the interior and outer skins to mirror each other, with both being comprised of distorted, diamond-shaped panels. Following consultation with facade manufacturer and installer Frener & Reifer, it was determined that such a layout could prove cost-prohibitive. Instead, the original complexity of the outer facade was maintained, while that of the interior was simplified to a more standard curtain wall format. Although the simplification of the double-skin enclosure reduced the cost and construction time of the project—construction began on May 2016 and the building was air- and- watertight by 2018—the assembly of the facade remained remarkably complex. "Every element in the facade, except the nuts and bolts holding it together, is unique," said the design team. "Each glass panel, each load-bearing column, is unique in its shape and in its relations to neighboring elements." There are 194 glass panels per floor for both the inner and outer facade. The inner facade is held at the top and bottom at each floor plate with base profiles and has a surface area of just under 25,000 square feet. Girder arms extend from the concrete roof slab, which in turn support the 388 aluminum-clad steel fins that line each elevation. According to Frener Reifer, "this made it possible to hang the fins from top to bottom and to transfer the load of the upper two floors to the roof." Additionally, the exact height of the fins could be altered on-site through the use of adjustable screws. To shade the broadly illuminated office space, the design team placed three-inch-thick aluminum Venetian blinds between the interior and exterior facades. Additionally, a catwalk is accessible from 24 points within the building between the two curtain walls, facilitating a straightforward maintenance program.

Clad in a high-performance curtain wall from Italian firm Focchi, the tower integrates 12 types of glass. Despite a rather complex massing, the geometry of the enclosure was refined into a canted, diamond-shaped panel, surrounded by triangulated panels set perpendicular to the slab edges. The overall effect is a faceted, three-dimensional version of the architectural corner—perhaps a recasting, or import, of the Miesian corner to one of Manhattan’s most significant public spaces. The project adds to a portfolio of high-rises designed by the Chicago-based practice (which also has offices in New York, San Francisco, and Paris) that explore “solar carving” as a formal and performative strategy. “'Solar Carving’ is one strand of a larger body of research about how we can make buildings responsive to the specific qualities if their context and climate,” said Studio Gang design principal Weston Walker. “To maximize sunlight, fresh air, and river views for the public park, we pushed the building toward the West Side Highway and carved away from its southeast and northwest corners according to the incident angles of the sun’s rays.” A growing issue for the High Line is the diminishing degree of sunlight caused by the development of Manhattan’s Far West Side. According to Walker, the city’s prevailing 1916 Zoning Resolution—legislation that mandated ziggurat-like setbacks to boost ventilation and light for city streets—did not anticipate the proliferation of midblock public spaces such as the High Line. “As-of-right zoning would have endangered rather than protected the park by allowing the tower to be built directly over the High Line.”

SHoP's Midtown supertall brings terra-cotta and bronze to new heights

Over the last two decades, SHoP Architects has pushed the envelope of facade design, leading a notable shift from predominantly glass-clad skyscrapers to supertalls incorporating a variety of materials. SHoP’s 111 57th Street is currently rising on Manhattan’s Billionaires’ Row—a stretch of dizzyingly luxurious towers. The tower stands out with a facade that incorporates three materials: terra-cotta, glass, and bronze ornamental work. The tower rises from a narrow lot located immediately behind and adjacent to the historic Steinway Building. In the mold of historic New York skyscrapers, the tower sets back and tapers upward along its south elevation. Both north and south elevations are clad in a glass curtain wall with vertical strips of bronze sprouting into finials at each setback.

As a result of the site’s constraints, the approximately 1,400-foot-tall tower’s width runs at a remarkably narrow 45 feet—the width-to-height ratio comes out to just 1:24. Partnering with BuroHappold Engineering, a key challenge for the project was developing a facade system capable of supporting the weight of cladding materials, notably the terra-cotta panels. Concrete shear walls back the facade for these two elevations with only select opportunities for punched window openings. “These select openings allow for vision glass to be used while the remaining glass panels contain shadow boxes,” said BuroHappold Associate John Ivanoff. “The unitized curtain wall panels are consistent in dimension across the width of the facade; the units are separated between different materials.” The composition of the east and west facades is formed by a trio of terra-cotta, glass, and bronze. Curtain wall–manufacturer Ellic Americas merged the three materials into approximately 4-foot-by-16-foot panels, with bronze filigree fluttering between vertical stripes of glass and terra-cotta. These panels were then delivered to the site, craned into position, and hung from concrete structural slabs similar to typical curtain wall systems. In total, nearly 43,000 terra-cotta pieces, mechanically fastened to a unitized aluminum curtain wall system, run across the two elevations. The design of the quasi-fluted terra-cotta strips was formulated using a 3-D wave geometry generated by a computational script. This geometrically focused design by SHoP was adapted by NBK Terracotta to conform to its specific fabrication parameters. The building is scheduled to be completed in 2020.
