Brought to you with support fromLos Angeles's Broadway is home to one of the finest assemblies of Commercial Style buildings in the country, consisting of steel structures with box-like massing, clad with richly ornamented terra-cotta or cast-iron, and lightened with large rectangular and divided windows. Constructed over several phases starting in 1908, the Broadway Trade Center, initially known as Hamburger's Department Store is a prominent example of the style within this district and was once the largest department store west of Chicago, sitting on half of a city block and measuring a total of 1.3-million square feet. After decades of decay and ultimately abandonment, the historic structure is getting a new lease on life due to the rehabilitation efforts of architecture and design firm Omgivning and contractor Spectra. Founded in 2009, Omgivning is not specifically a preservation architect, but the firm has established a particular expertise in the rehabilitation of historic structures within the Los Angeles-area and had led the overhaul of dozens of neglected structures.
terra-cotta cladding, who joined the restoration to replace damaged components. Only so much of the structure’s condition can be gleaned from research, and contractor Spectra handled the bulk of on-site inspection. “The survey entailed a hands-on inspection of the terra-cotta and windows,” said Spectra project manager Dick Gee. “A visual survey can only identify so much, while a hands-on survey after scaffolding is erected allows for a more accurate reading of the building.” Most of the terra-cotta was repaired in place; color-matching mortar applied to tile cracks, and faded segments brushed down and repainted. If a section of cladding proved non-salvageable, Spectra measured individual components and produced molds that were subsequently shipped to Gladding McBean's facilities just outside of Sacramento and reproduced to match their original size perfectly. Replacing and repairing the fire escapes and window frames were the other significant aspects of the facade restoration. For the latter, Spectra built an entire woodshop within the building to restore the decaying windows and immediately reinstall them—a more cost-effective and ultimately more pragmatic option than repairing offsite. Exterior restoration is essentially complete, while interior building renovations are ongoing.Historic tax credits are a key component to the feasibility of restoration projects and maintaining the original design is an inherent requirement. “In terms of facades specifically, we knew that we needed to maintain unaltered facade on all four elevations to comply with the requirements of working with historic buildings,” said Omgivning projects director Peter Rindelaub. Conforming to these requirements also led Omgivning to place new building air supply and exhaust louvers within a rooftop addition, while obscuring the path of utilities to the new electrical transformers. Restoration of the facade began with exhaustive archival research of the department store. While historic photographs were readily available, the team had to procure shop drawings from ceramics manufacturer Gladding McBean, the original producer of the
Brought to you with support fromMidtown East is a competitive Manhattan neighborhood to design a new tower; the skyline is crowded with an assembly of jostling skyscrapers and landmarks constructed over the last century. Completed in 2019, The Centrale is an 803-foot-tall residential tower designed by Pelli Clarke Pelli Architects and developed by Ceruzzi Properties. The building strikes a middle ground between the surrounding Art-Deco icons and post-war glass curtain walls with panels of terra-cotta chevrons and solar-control glass. The 220,000-square-foot tower is located mid-block and is flanked on either side by pre-war midrises of stepped massing and clad in detailed yellow brick, limestone, and ornamental masonry. The challenge for the architectural team was how to incorporate these historical elements into a contemporary mold for a remarkably slender project.
SHoP's 111 57th Street, the narrow profile of the tower—floor plates are approximately 3,000 square feet— required significant shear walls on the east and west elevations, and is further stabilized by a 400-ton tuned mass damper located at the bulkhead. A series of hinged setbacks occur as the tower rises, shifting the face of the primary elevation to the northeast and northwest in a playful nod to contextual massing. The orientation of the terra-cotta panels corresponds to the alternating facade planes, and are colored cream and dark brown. Using the latter was a practical solution to heighten the depth of a relatively shallow architectural detail, and the terra-cotta bands form something of an abstract impression of fluted buttresses. The design of the facade and the dimensions of the curtain wall units were impacted by the constraints of the site, and contractors relied on a hoist run rather than a conventional crane to install the panels. Typical curtain wall units measure approximately 5'-8" by 11' and 3' by 11', and the terra-cotta units are 4'-4" by 11'. According to Pelli Clarke Pelli associate principal Jimmy Chang, "The design team had to work with this limitation and modify the much more expressed facade (deep saw-tooth profile), to smaller and shallower profile units." Through scaling down the unit sizes, fabricator and installer Permasteelisa saved time in assembly and installation which ultimately translated to overall cost savings of the curtain wall. On the second day of Facades+ NYC, Pelli Clarke Pelli Architects, engineering firm BüroEhring, and Roschmann Steel & Glass Construction will lead an intensive workshop titled "(P)ReFabricate: An Interactive Reinterpretation of Prefabricated Building Enclosures." Attendees of the workshop will collaborate closely with the team of nine instructors to recalibrate the designs of one of eight prefabricated case studies according to a change in context, contemporary energy standards, and ease of assembly."We were cautious not to fall into the trappings of architectural style and appearance, but rather to emulate the repetition and movement of the Jazz Age and the expressive machinery that celebrated the still young industrial age," said Pelli Clarke Pelli principal Craig Copeland. "The chevron emerged as a key motif for the project; and we soundly incorporated it throughout from the scale of the skyline, to the touch of many close-up details." The base of the project begins with a 100-foot-tall metal screen that cloaks shared residential spaces and is indented with the tower's prevailing chevron detail. Lifting the residences measurably above street level and shrouding the podium with perforated metal is a clever aesthetic solution to engineering requirements. Similar to
Brought to you with support fromPhiladelphia's Schuylkill Yards is undergoing a massive redevelopment by Brandywine Realty Estate that will bring half-a-dozen new buildings, totaling approximately six million square feet, into the center of the city. Practice for Architecture and Urbanism (PAU), is joining the fray with JFK Towers; a duo of cantilevering, offset mixed-use buildings clad in terra-cotta and aluminum. The project, which broke ground in November 2017 and is master-planned by SHoP Architects, follows a spate of railyard redevelopments around the country; ranging from the ongoing construction at Hudson Yards to the 244-acre revamp of Sacramento's former Union Pacific Railyards. In this instance, the redevelopment is located atop the former parking facilities at the adjacent 30th Street Station, rather than decking over the yards that neighbor the Schuylkill River.
terra-cotta base for the vaulted arcade and a similarly-colored polychromatic paint coating over the aluminum cladding. The west tower will be subject to a similar material treatment but in a brownish-gray hue. The fenestration pattern that will rise from the arcaded base of the two towers will be a clear nod to commercial high modernism, with ribbons of windows divided by protruding vertically-oriented fins, and is a significant diversion from the predominantly all-glass towers otherwise rising throughout the city. PAU associate partner Mark Faulkner and Brandywine Realty Trust vice president Joseph Ritchie will be joining the panel "Schuylkill Yards First Facades: Architects’ and Developers’ POV" at the Architect's Newspaper's upcoming Facades+ Philadelphia conference on October 18.As a tabula rasa, the architects enjoyed the opportunity of shaping an entirely new district that will be visibly prominent from most vantage points within Philadelphia—the east tower will reach a height of 512 feet and the west tower will stand at 360 feet—and will effectively bridge Center City to University City across the Schuykill River. "We generated the forms through the site geometry. Rail is adjacent on three sides which bifurcate the buildable area at different angles and heights informing the cantilevers and stacking," said PAU associate partner Mark Faulkner. "The breaking of our massing into low, mid, and high-rise blocks yields a playful stacking of volumes, efficiency for the complex mixed-used program, and a unique addition to the skyline that announces this important new neighborhood in the city." Although the planned towers of Schuykill Yards will dwarf surrounding structures in this corner of West Philadelphia, the design team has included several material choices that will tie the JFK towers to the city-at-large. Outside of Center City, Philadelphia is comprised of residences and small businesses rendered in often brownish-red low-rise brick and masonry. An additional influence can be found in the historic red metal coaches used by the defunct Pennslyvania Railroad headquartered in Philadelphia. The east tower of PAU's duo will appropriate this heritage with a red
Brought to you with support fromNow in its fourth consecutive year, the Architectural Ceramic Assemblies Workshop (ACAW) has reached a new level of maturity. The annual conference, hosted in Buffalo, New York, counted a total of nine teams hailing from leading architectural and engineering firms across the country. For attendees, the gathering is an opportunity to part the veil behind the architectural terra-cotta manufacturing process, experiment with new concepts, and physically transform them into full-scale prototypes. The collaborative project is the product of an ongoing partnership between manufacturer Boston Valley Terra Cotta (BVTC) and the University at Buffalo School of Architecture and Planning (UB/a+p); engineering firm Walter P Moore served as an additional sponsor for the event. Buffalo, New York is home to a broad range of 20th-century architectural heritage. It should then come, perhaps, as no surprise that BVTC made its bones in the field of architectural preservation. The company, originally founded in 1889 as Boston Valley Pottery, was purchased by the Krouse family in 1981 who converted the operation into a manufacturer of architectural components. Beginning with local restoration projects such as Louis Sullivan's Guaranty Building, BVTC has since partnered with UB/a+p in the use of digital documentation to mass-produce historic architectural pieces. The use of digital design has facilitated BVTC's ascent in the field of custom terra-cotta assemblies; current projects range from Kohn Pedersen Fox's (KPF) supertall One Vanderbilt to Morphosis's Orange County Museum of Art. The teams were made up of new attendees and familiar faces who had developed their prototype concepts in the months leading up to the conference. The prototypes largely followed the ACAW statement of intent, which encouraged an exploration of the intersection between ceramic furniture and cladding. Projects ranged from SHoP Architects' self-supporting structure formed of interlocking terra-cotta units to KPF's manipulation of geometry and glaze embedded atop a concrete panel. There was also a significant alteration to the overall procedure of the conference. Andy Brayman, founder of the Kansas City ceramics collaborative Matter Factory and past ACAW attendee, recently partnered with BVTC to develop the company's first off-site Research & Development Lab within his own facility. "This strategy is helpful when taking on the ACAW projects which by their very nature contain at least one element (and often several) that could be considered experimental," said Brayman. "The bulk of the technical know-how comes from BVTC and it is augmented by research that has been done at the Matter Factory. Taking the projects out of the main factory that is focused on the production of existing jobs allows a different dynamic to take place." The conditions present at the BVTC are effectively replicated at the Kansas City collaborative as the gas-fired kilns are produced and calibrated by the same Italian manufacturer. Keynote speakers, many of them also workshop attendees, included Andy Brayman; Dr. William M. Carty, a ceramics professor at Alfred University; Billie Faircloth, partner at KieranTimberlake; Sara Lopergolo, partner at Selldorf Architects; Sameer Kumar, director of enclosure design at SHoP Architects; Jason Vollen, vice president High Performance Buildings AECOM. What is the overarching goal of this annual earthenware gathering? According to UB/a+p associate professor and conference organizer Omar Khan, "ACAW’s ambition is to make Western New York a recognized center for architectural ceramic research. It is the only one of its kind and we feel that it will influence design and innovation in terracotta usage. From this year’s success, we are already receiving many inquiries to participate next year but our intention will be to internationalize the participants to some extent. This will put other issues and traditions in the mix, which we feel will help us better address more global concerns." Let's see what the future has in store for this corner of the Empire State.
Brought to you with support fromOver 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.
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.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

Designed by Portland’s OFFICE 52 Architecture, the intervention consolidates classrooms, academic advisors, counseling, and tutoring for nearly 23,000 students under one roof. The 64,000-square-foot academic building carefully inserts itself into the campus with a variegated terra-cotta and brick facade with moments of glass curtain wall. The building, like much of the campus, rises as a rectangular mass with a series of incisions and setbacks for daylighting and programmatic purposes. To match with the cornice height of the surrounding structures, Tykeson Hall tops out at four stories.
rainscreen system composed of 3,100 vertical tiles manufactured in Germany by the Shildan Group. This is the first application of terra-cotta on the historic campus in over eighty years—and earlier examples are chiefly decorative rather than performative. All of the terra-cotta tiles roughly measure six inches by three-to-five feet and are clipped to an aluminum grid at both their top and bottom. In using such a straightforward fastening method, the tiles can be easily removed, repaired, or replaced. Visually striking from multiple vantage points across the campus, the pattern of the matte-glazed terra-cotta tiles was developed from the study of Oregon's natural landscape and the architectural context of the University of Oregon's campus. "We looked at numerous color combinations and determined that five colors were necessary so that no color was ever repeated adjacent to itself on any side," said Office 52 founding principal Michelle LaFoe and principal Isaac Campbell. "We then produced keyed drawings that called out every one of the 3,100 tiles, and we made full-scale mock-ups of the final options in our studio. The final resolution of the palette came down to a gray palette that had both warm and cool colors." The most common material element found throughout the campus is brick, loadbearing in the case of historic structures, curtain for the contemporary. The existing brick color palette is largely brownish-red and arranged according to the simple Stretcher bond pattern—bricks overlaying each other midway on each successive course. For the project, the university required OFFICE 52 Architecture integrate this overarching aesthetic into the design of Tykeson Hall. To this end, the design team researched prospective brick layouts to enliven the facade along the east, north, and south elevations of the project. "During our research, we discovered an interesting pattern known as an English Cross bond, which creates a diagonal pattern by staggering the vertical mortar joints from course to course," continued LaFoe and Campbell. "Intrigued with this pattern and seeking to increase its scale, we added a course of longer Norman bricks to the pattern, creating a new pattern which we called a Norman Cross bond." For the coloring of these three elevations of brick, OFFICE 52 Architecture worked with Mutual Materials Hardscape and Masonry to develop a custom-blend of their Columbia Red and Autumn Blend brick types. In total, 78,000 bricks were used for the project, with the design team using building information modeling software to ensure the pattern corresponded with window returns and corner finishes. The bulk of the project's fenestration is composed of punched window openings. However, one-story glass curtainwall projects from the prevailing sedimentary mass along the north, west, and south elevations.

“The way we cool our buildings right now is totally wrong,” said Indian architect Monish Siripurapu in a video produced the United Nations' Environment program. The words are bleak, but arguably true; the electricity and hydrofluorocarbons most modern cooling systems demand ironically warm the planet overall while they cool our conditioned spaces. On top of that, with global temperatures rising and worldwide populations growing, demands for cooling are only increasing. More eco-friendly options are urgently needed, and Siripurapu’s New Delhi–based firm Ant Studio has proposed an affordable, scalable, sustainable, and aesthetically appealing solution to the problem of air conditioning. Ant Studio’s mission is to combine “art, nature, and technology,” and its temperature-regulating solution is designed to be as much an art installation as a cooling system. The Beehive, as the system's first iteration is called, was built to ameliorate high-temperature conditions for laborers at the Noida, Uttar Pradesh–based manufacturer Deki Electronics, where generators and other equipment output their own heat, adding to high outdoor temperatures. The Beehive is part of a larger exploration by the firm that leverages terracotta tubes and water as part of a low-energy cooling system. The Beehive, so-named for its honeycomb-like structure, follows an Indian tradition of using earthenware to cool water. “Traditional architecture has so much wisdom,” said Siripurapu. The ancient process has been wholly modernized, with tools such as computational fluid dynamics modeling, as well as the addition of low-energy water pumps and, if needed, electric fans. But instead of using fans with the Beehive installation, Ant Studio’s cooling device was placed right in front of the exhaust vents of the diesel generator near where workers at the factory were active. This was able to drop the “scorching” air being expelled from the generator from 122 degrees Fahrenheit to 97 degrees Fahrenheit, while lowering the overall temperature in the area and reportedly consuming 40 percent less energy than other cooling systems, not to mention using no refrigerants. The cooling system consists of arrays of open terracotta cylindrical cones (designed in such a way to maximize surface area and fired at “mid-level” temperatures to maintain the clay’s ability to absorb moisture from the air) over which water is poured. The water, which adheres to the clay, naturally lowers in temperature due to evaporative cooling, which in turn cools the air passing through the tubes. The water can be recycled throughout the system, requiring only infrequent topping off, and biofilms of microalgae that grow on the clay surfaces can actually aid in air purification, according to the firm. Further, as explained in an informational video from the firm, “all materials are recyclable, reusable, or biodegradable.” While the Beehive at Dika Electronics took on a particular nature-inspired form, the system can be designed in all manner of shapes and sizes, and is inherently modular, making fabrication and assembling on-site simple. The overall hope with the project is to devise a system that is “functional and visually appealing at the same time.” Ant Studio views the cooling systems as a work of sculpture as much as a functional tool. The terracotta cooling systems also could have broader social impact. Besides being a cheap, energy-efficient way to cool factories and public spaces, the craft required to manufacture the tubes creates local employment and skill-building opportunities. It also keeps alive traditional manufacturing techniques that provide a unique, hand-hewn character that industrial cooling systems certainly lack. The clay-based materials also mean a net reduction in embodied energy for these cooling systems. Ant Studio has also proposed a smaller system which they’re calling ETHER, a cooling device for personal use and small spaces that resembles something like a cross between a Dyson fan and an ancient artifact. Ant Studio’s cooling projects were one of the twelve winners of the United Nations’ Asia-Pacific Low Carbon Lifestyles Challenge and have been nominated for the Clean Energy Challenge from What Design Can Do, a “platform” and series of global conferences on design. Nominated teams are given the “opportunity to improve their project” with the final winners to be announced on March 6.

The firm collaborated with local sculptor Bob Vangold to embed a sculptural form within the facade. To achieve this effect, the sculpture is anchored along the horizontal roof edge with a series of base plates. On a larger scale, the Olson Kundig-led renovation of Seattle’s Space Needle recently wrapped up after 11 months of sky-high construction. The project entailed the removal of decades of haphazardly designed additions in favor of an open-air viewing area. Working with facade consultants Front Inc., the design team converted floors within the top of the Space Needle to transparent glass panels providing revolving views on the city below, and wrapped the observation deck with 11-by-7-foot, 2.5-inch-thick glass panels produced by Thiele Glas and installed by a team of robots designed by Breedt Production. Just south of Seattle’s Space Needle, the trio of Amazon Spheres consists of approximately 2,500 glass panels suspended over a complex steel truss system. Collaborating with NBBJ Architects, Front Inc. led exhaustive case studies, with the help of custom-built software tools, to develop a glass tiling scheme matching visibility requirements for occupants and light exposure for the greenhouse within. Following the creation of multiple digital models, Front Inc. led the fabrication of full-scale mockups of the design to test the computer-generated models. Representatives of these two firms, as well as Gensler, Katerra, Werner Sobek, Thornton Tomasetti, and Eckersley O'Callaghan, will be on hand to dive deeper into the architectural resources and trends present in both Seattle and the rest of the country.

zoning and site constraints, the massing of the west facade is set back, with eight floors of office space rising midway through the elevation. The development’s facade is defined by horizontal and vertical bands of white brick, produced by Belden/Tristate Brick, which frame a charcoal-colored terra-cotta curtain wall. For the color scheme and materiality of 363 Lafayette, Morris Adjmi reinterpreted the area’s historically narrow terracotta mullions, window surrounds, and brick piers, into a much wider layout. Designed by the firm and crafted by Buffalo’s Boston Valley Terra Cotta (BVTC), the geometric pattern of the terra-cotta reliefs was conceived by the design team as an abstraction of neighboring Classical and Richardsonian Romanesque detailing. The custom-made terra-cotta rainscreen was installed on BVTC’s TerraClad clip system that attaches to a perimeter concrete beam and a medium-gauge framing wall. A series of gaskets and isolators allow the system to adjust to thermal expansion while reducing wind-induced vibration. Elongated rectangular windows, fabricated by TriStar with Win-Vent frames and Vitro Glass, are placed between chamfered terra-cotta mullions. Why does the building twist? Lafayette Street used to proceed north from Great Jones Street until the end of the 19th century when the street was excavated from the IRT subway. The excavation of the street led to the creation of odd-shaped sites, such as 363 Lafayette. According to the design team, “the building’s twist serves to reflect the cut of the street and to architecturally engage the setback with the lower portion of the building.”363 Lafayette’s site is prominent, with three visible elevations to the north, south, and west. The ground floor of the building is dedicated to commercial space and extends from Great Jones to Bond Street. Due to
For the third year in a row, manufacturer Boston Valley Terra Cotta (BVTC) and the University at Buffalo School of Architecture and Planning (UB/a+p) in upstate New York hosted the Architectural Ceramics Assemblies Workshop (ACAW). The weeklong event is a gathering of architects, engineers, and artists and offers a fast-paced opportunity for attendees to get their hands dirty physically testing the capabilities of terra-cotta design. Other sponsors of the gathering include Western New York’s Alfred University, an institution with expertise in glass and ceramics, and Rigidized Metals Corporation, a producer of deep-textured metal for exterior and interior cladding, among other products. “Architects designing with industrially produced ceramic components may have little material understanding of clay for large-scale production, while most artists trained in ceramics may have few opportunities to explore the medium at a scale beyond the individual object,” said Bill Pottle, BVTC’s Director of Business Development and organizer of the gathering. “At ACAW, architects, engineers, and educators collaborate with designers and manufacturers in order to deepen their understanding of designing with architectural terra-cotta.” BVTC was founded in 1889 as Boston Valley Pottery, a brick and clay pot manufacturing facility located on the outskirts of Buffalo, New York. The Krouse family purchased the facility in 1981 and transformed it into a cutting-edge architectural terra-cotta factory with a global footprint. Currently, projects range from the restoration of New York’s Woolworth Building to the cladding of Morris Adjmi Architect’s 363 Broadway and Kohn Peterson Fox’s One Vanderbilt. Keynote speakers, many of them workshop attendees, included Anne Currier, a clay sculptor and professor; Dr. William M. Carty, a ceramics professor at Alfred University; Christine Jetten, a ceramics and glazing consultant; Gerd Hoenicke, Director of Pre-Construction Services at Schüco; Matthew Krissel, partner at KieranTimberlake; Craig Copeland, associate partner at Pelli Clarke Pelli Architects; and Christopher Sharples, principal at SHoP Architects. This year, over 60 attendees participated in the workshop, which emphasized the role of pre-design and research at the early stages of a design project. Both the number of attendees and the overarching objectives of the workshop have evolved since its 2016 inauguration. The first event was largely a sandbox tutorial, featuring 20 attendees learning the basics of terra-cotta production. In its second year, ACAW and its 40 attendees focused on the bioclimatic function of terra-cotta in contemporary design and the retrofitting of structures. This year, building upon their experience at previous workshops, the attendees, divided into six teams, began researching and developing their prototypes in March. Designs were submitted to BVTC prior to the conference for prefabrication. Throughout the week, the teams received technical support from both BVTC and UB/a+p.
Today tennis takes over the world’s stage with the start of the 2018 US Open. Now in its 50th year, the tournament will play out within the newly renovated USTA Billie Jean King National Tennis Center in Flushing, Queens. The five-year, $600-million project is now finished with the opening of the site’s final project: the Louis Armstrong Stadium, the world's first naturally ventilated tennis arena with a retractable roof. Over the next two weeks, hundreds of thousands of fans will descend upon the city to watch the final Grand Slam of the year, and while the tennis champions themselves are the real stars of the show, the stadium architecture will be prominently on display. The highly-anticipated renovation marks the end of the site’s fraught history with deteriorating courts and rain delays messing up major events. Designed by Detroit-based firm Rossetti, the new 14,000-seat Louis Armstrong Stadium evokes the feel of the old arena, which the USTA opened in 1978, but includes modern feats of engineering and sustainable design additions that bring it into the 21st century of sports architecture. The stadium boasts 40 percent more seating than its predecessor in two levels of precast concrete bowls and an advanced shading system that’s anchored by a fixed, cantilevered roof deck. Matches can proceed rain or shine thanks to the masterfully-engineered two-piece, moving roof that covers the court. Called a “complex, stackable sun room” by the architects, the retractable roof features 284,000-pound PTFE fabric panels that create a 38,160-square-foot opening after traveling 25 feet per minute in under seven minutes from the stadium’s edge. The transparent, lightweight fabric diffuses a soft light into the arena when closed, transferring 73 percent of the sun’s energy. The sides of the stadium additionally allow breezes to flow through the facility. Rossetti placed 14,250 overlapping terracotta louvers on the north and south sides of the structure that act as horizontal window blinds. The siding material is a nod to the traditional brick buildings found throughout the tennis grounds. Construction began on the new stadium two years ago when the 52-year-old Armstrong arena was demolished after the 2016 championship. Originally built for the 1964 World’s Fair, the structure was much-loved because it gave fans an intimate experience and unbeatable views with sky-high, stacked seating. Louis Armstrong Stadium 2.0, as many are nicknaming it, does the same but with a more porous, contemporary design. Plus, it has a built-in umbrella that ensures consistency of play no matter the weather. To celebrate its opening, Armstrong will hold more matches during the 2018 US Open than its neighboring Arthur Ashe Stadium, an 18,000-seat arena that also received a flexible roofing system during the renovation. Both stadiums will hold two matches at night, but Armstrong will see three during the day while Ashe will host two.
