Brought to you with support fromBoston’s Seaport District is no stranger to development; the 23-acre site lies east of the Fort Point Channel on the Inner Harbor, and over the last two decades has transformed from a largely barren deindustrialized waterfront to an effective extension of the city's core. Pier 4, a 400,000-square-foot mixed-use project designed by local firm Elkus Manfredi Architects, is an exemplar of this trend and proposes an alternative to boxy glassed massing with staggered floors and eye-catching soffits of aluminum composite panels. The project is located immediately adjacent to the HarborWalk and the Institute of Contemporary Art and is prominent from both an urban and visual standpoint. Considering its location, the city dictated that the bulk of the building’s ground floor be dedicated for public use—the lobby can be passed through by pedestrians and features a range of retail spaces. In keeping with the project's public-facing manifesto, the primary entrance, in a particular flourish, is surrounded by a prismatic display of polished and reflective aluminum. From this base, the tower rises to a height of 13 stories.

Brought to you with support fromThe University of Oregon’s Phil and Penny Knight Campus for Accelerating Scientific Impact is one of the most significant expansions to the Eugene campus following the construction of OFFICE 52’s Tykeson Hall and Hacker Architect’s Berwick Hall. The project is a collaboration between design architect Ennead Architects and architect-of-record Bora Architects, with Thornton Tomasetti acting as facade consultant, and will enclose state-of-the-art research facilities with a double-skin of fritted glass and an Ethylene Tetrafluoroethylene (ETFE) membrane. The campus expansion began in March 2018 with the groundbreaking of the 160,000-square-foot first phase structure (which came with a $225-million price tag); the total budget for the campaign is approximately $1 billion. This initial phase consists of two, four-story L-shaped towers centered around a shared courtyard, which is connected to the rest of the campus to the south by a pedestrian bridge spanning over Franklin Boulevard.
Brought to you with support fromOne Vanderbilt, designed by Kohn Pedersen Fox (KPF), is not a subtle project; the tower topped out in September 2019 and rises from an entire city block with a behemoth massing to a height of just over 1,400 feet. The tower is visible across the metropolitan region, from the New Jersey Meadows to the Bronx-Queens Expressway, and stands out from the pack with spandrels of fluted terra-cotta and canted glass panels. The building is located in the heart of Midtown, standing immediately adjacent to Grand Central Terminal and surrounded by turn-of-the-century office towers—approximately half-a-dozen historic structures met the wrecking ball to make room for the project. For KPF, this context, and perhaps the acts of destruction required in the act of creation, led to two primary design objectives: An accessible podium with an engaged street wall on all four elevations, and a material palette that kept with Terminal City. As noted by KPF design principal Jeffrey Kenoff, “Our use of terra-cotta echoes the work of Guastavino at Grand Central, while the bronze podium allows the building to nest into a Midtown patina.”
Permasteelisa North America’s project office leader, the team typically installed four floors per month using a mini-crane projected from the floor slab above. The unitized panels were fabricated at Permasteelisa Group’s factories in Connecticut and Montreal and were shipped to the site by New Jersey-based superload logistics specialist Farren International. Buffalo-based manufacturer Boston Valley Terracotta (BVTC) produced the tower’s architectural terra-cotta and was involved in its modeling since the concept design phase. There are two custom glazes, resulting from half-a-decade of collaboration between BVTC and KPF, applied to the tower’s terra-cotta panels; a darker glaze for the larger soffit tiles and a light, high-gloss glaze used for the curtain wall spandrels. The bulk of the tiles were extruded—the clay was forced through a steel die to produce a hollow cored unit which is subsequently cut, dried, and fired. In total, there are over 2,400 soffit tiles, which measure 5'-0" x 2' - 6", and 26,000 spandrel tiles, which have a standard width of approximately 5 feet. Each diagonally-oriented flute is just over a foot in height, and are split by approximately two-inch seams. The tiles are held by a straightforward system of mullions and stack joints, however, special attention was paid to areas that incorporate natural-ventilation components. The canted glass panels run the same width as the spandrel tiles and were produced by Tvitec Spain and treated with Guardian SunGuard HP Neutral 50/32. Each IGU module is composed of a 3/8" outer lite, a 1/2" air space, and an inner lite of two 1/4" panes. The project is scheduled to wrap up in 2020.Excavation of the site began in 2016 to make way for one of the city’s largest concrete pours, with the foundation requiring approximately 4,000 cubic yards of concrete. Since then, construction manager AECOM Tishman and facade installer and fabricator Permasteelisa have proceeded at a dizzying pace. According to David Mangini,
Brought to you with support fromThe International Spy Museum presents a striking figure in the relatively staid streetscape of Washington, D.C. The building opened in May 2019 and was designed by London-based Rogers Stirk Harbour + Partners (RSHP) in collaboration with architect-of-record Hickok Cole, and replaced the original home of the Spy Musem that was constructed in 2002. The project is a demonstration of high-tech architecture; notably, the pleated glass veil shrouding an atrium and circulation space—both cantilevered off the primary black aluminum-clad exhibition-space structure. L'Enfant Plaza is not the most exciting corner of Washington, D.C.—the megaproject, designed by I.M. Pei and developed by William Zeckendorf, is often derided for its overwhelming massing and dearth of pedestrian amenities. The International Spy Museum is located within a forecourt of the megaproject and, in its idiosyncrasy, establishes a formidable presence in the area. The project rises to a height of 130 feet, the height limit within the city, and is primarily encased in a tapered aluminum black box lifted off the ground by pilotis. Total square footage for the museum comes out to approximately 120,000 square feet divided across seven stories.
Brought to you with support fromCompleted in December 2019, The Looking Glass is a four-story mixed-use renovation for developer Warenar Real Estate that offers a thoughtful solution for merging contemporary design within the centuries-old Museum Quarter of Amsterdam. Designed by Dutch architectural practice UN Studio, the approach addresses both the contextual and use demands of the site with finely curved glass panels and well-crafted brick masonry. The project faces the Pieter Cornelisz Hooftstraat, one of Amsterdam's primary retail corridors. Like much of the Netherlands’ architectural vernacular, the area is composed of three to four-story structures of sober restraint. Ornament is largely limited to spandrel brickwork detailing and carved wood brackets at the cornice—this is not a setting for ostentatiousness. UN Studio’s design respects this heritage while heightening the streetscape with a constrained aesthetic flourish, that, in its curvaceousness and subtle steelwork, bears resemblance to a playful Art Noveau storefront in the style of Victor Horta or Frantz Jourdain.
glass boxes and brickwork. At the second story, the glass boxes protrude significantly from the facade before curving and overlapping the groundfloor’s glazing. The maneuver lends a flowing quality to the facade while maintaining full transparency of the lintel and brick-chevron frieze. Each of the glass panels is bonded with structural silicone, and their seams are obscured by narrow and polished stainless steel frames. On the ground floor, the concave underbelly of each curved panel transitions to a broad stainless steel strip that furthers material differentiation at street level. The windows were assembled off-site—no small feat considering that their average height is approximately 27 feet—and installed as prefabricated pieces. The renovation, which removed the first three stories of brick in favor of glazing, required the insertion of narrow columns of glass-fiber reinforced concrete (GFRC) panels between the window bays. Following the installation of glazing, the GFRC components were covered in a rigid insulation layer. The new masonry is entirely comprised of hand-molded, reddish-brown brick slips produced by the Van der Sanden Group; the brick slips are glued to the insulation membrane and largely follow a Dutch-bond pattern. Although the inclusion of brick on the renovated facade is only surface level, their hand-molded fabrication lends an imperfect and wrinkled surface with slight variances in dimension—a gradient of patina blending with the overall streetwall.

Brought to you with support fromSet to open in mid-March, 2050 M Street is a novel commercial project located in the Dupont Circle neighborhood of Washington, D.C. REX, an architecture and design firm based in New York, is the design architect for the project. In contrast to the imposing massing of Beaux-Arts, Brutalist, and droll mid-century Miesian bootlegs that dominate the capital, the project presents a subtle and refined approach to the office block typology with its array of fluted glass panels. Founded two decades ago by Joshua Ramus, REX has led an impressive array of completed and ongoing projects, including the Ronald O. Perelman Performing Arts Center at the World Trade Center, Brown University's Performing Arts Center, and the retrofit of 5 Manhattan West. An instrumental collaborator in over thirty of their projects is facade consultant Front Inc., with whom they share an office space in DUMBO, Brooklyn. “Both companies share a mutual understanding of the other’s values, aspirations and skillsets with each practice leveraging the other to create opportunities for innovation within real and tight project constraints,” said REX founding principal Joshua Ramus and Front Inc. founding principal Marc Simmons. “REX and Front also share a rigor and discipline during an always iterative design process but also as pertains to creative procurement, in close cooperation with owner and construction manager, and focused quality review during the shop drawing, prototyping, testing, assembly and installation phases of the work.”
Tishman Speyer is the developer of 2050 M Street, whose construction was overseen by the managing director of design and construction, Rustom Cowasjee. The non-concrete block structure construction began in March 2018 and facade installation wrapped up in August 2019. The massing of the twelve-story office building is rectangular and boxy, a common trait in D.C. to maximize square footage within the city’s zoning constraints and height limitations. For REX, one of the challenges of the project was to establish a lightness and verticality for what is an overwhelmingly horizontal project. To heighten the sense of verticality of 2050 M Street, the design team turned towards the architectural technique of fluting; a feature stemming from antiquity, where shallow vertical grooves were largely applied to columns and pilasters. In place of detailed masonry, the enclosure is composed of approximately 900 curved IGUs, their outward-facing concave surfaces treated with a pyrolytic coating, and form a high-relief facade with a striking kaleidoscope-like impression of the surrounding streetscape and weather features. Each floor-to-ceiling panel measures 11'-3" by 5'—those at the top two floors are 12'-10" and 12'-13" tall and form a quasi-cornice above the top slab edge—and have a 9'-6" radius formed through a heat roller tempering process. The project is topped by a separate row of 4'-tall panels that serve as a parapet. The curvature of the panels also plays a critical role in the office building's remarkable degree of transparency; the compressive strength of the curves allowed for the panels to be mullion-less, and only supported by brackets anchored to the floor slab and laterally restrained at the head to allow for differential movement. As an additional measure to heighten the lightness of the facade, the structure’s perimeter columns are set back over 12 feet from the glazing to permit nearly undisrupted outward views. Following REX’s design intent for 2050 M Street, Front Inc. developed a comprehensive system with prescriptive specifications for all aspects of the glass assembly. The design and analysis package was the basis for the facade bid package for prospective fabricators and sub-contractors—Tishman Speyer funded full-scale mockups from each bidder for on-site evaluations by the design team. Ultimately, two firms were signed on to handle fabrication: Tianjin North Glass handled the fabrication of the IGUs cut from Guardian Glass and AGC Asia glass sheets, while Fabbrica managed the aluminum-and-glass modules at their Connecticut facility and handled shipment to Washington, D.C. “The engagement with the glass fabricators started during schematic design and continued even after the last piece of glass was shipped to the site,” continued Ramus and Simmons. “The actual design of the panels remained unaltered when we received manufacturer feedback; the focus was confirming the viability of cost, quality and schedule of fabrication.” REX founding principal Joshua Ramus, Front Inc. founding principal Marc Simmons, and Tishman Speyer managing director of design & construction Rustom Cowasjee will present 2050 M Street at Facades+ Washington, D.C. on February 20 as part of the "Curved and Pleated: Advanced Applications of Glass" panel.
James Carpenter Design Associates lets the light into Nordstrom with gargantuan double-curved glass panels
Brought to you with support fromOver the last four decades, James Carpenter Design Associates (JCDA) has been a pioneer in advanced glass installations and facade design, with projects ranging from the Museum at the St. Louis’ Gateway Arch to the Fulton Center Sky Reflector Net. The new Nordstrom flagship store in New York is located at the podium of the Adrian Smith + Gordon Gill Architecture-designed Central Park Tower, the world’s tallest residential structure. The storefront is yet another demonstration of JCDA’s proficiency in lightness and transparency, evident in the undulating curtain wall of double-curved and supersized glass panels. The JCDA-designed curtain wall is the public face for the retailer along the store's south and north elevations—the store also includes several buildings located on adjacent Broadway. Reaching a height of seven stories, the translucent exterior presents a striking streetwall that, in certain respects, resembles the articulated stone-and-brick massing of abutting historic structures, and, according to JCDA, its wavelike form is an homage to the East and Hudson Rivers bounding Manhattan.
Brought to you with support fromLocated just south of San Francisco's Financial District and blocks away from the bay, MIRA Tower is a housing development that grabs your attention with a highly detailed geometric form. The project joins a spate of recently completed and under construction towers in the Transbay Development Zone, including Pelli Clarke Pelli Architects' Salesforce Tower and the Heller Manus Architects' 181 Fremont. Designed by Studio Gang Architects in collaboration with facade consultant Heintges and fabricator Permasteelisa, the tower presents a spiraling aluminum-and-glass facade arranged in a panoply of bay windows and terraces. Developed by Tishman Speyer, the size of the project is formidable and consists of both a tower and a terrace of townhouses—with a footprint of 50,000 square feet and spanning 700,000 gross square feet. To comply with FAR constraints and rules set out by the district zoning guidelines, the initial design reached a height of 300 feet. Following a request to the city government, the allowable height of the tower was raised to 400 feet with the inclusion of 156 below-market-rate apartments, or just under half the total number of units.
Studio Gang turned towards the architectural vernacular of the San Francisco-area for the overall form and massing of the tower and townhomes, reinterpreting classical bay windows into a contemporary gesture. There are ten different bay geometries: each is an isosceles triangle 14-feet wide and with differing spandrel and glazing dimensions, and with a maximum depth of six-and-a-half feet. Thirty bay window units are found at each level, adding up to, in total, over 1,000 across the tower. Shifting the bay geometries was not the initial direction of the project but a discovery during the design phase that, through offsetting and repeating a set of variations every 10 floors, a profound level of detail could be added to the project without causing undue complications in fabrication and construction. Through the inclusion of bay units across the facade, each residence is afforded daylight from multiple directions and sweeping views of the city at large. Facade consultant Heintges joined the project during the early schematic design phase to both conceptualize the enclosure design and develop a facade system with sufficient waterproofing and compatibility with locational seismic requirements. “In this system, the windows act like a freestanding window wall, loaded at the sill and allowing movement at the header,” said the Studio Gang design team. “The spandrel panels, on the other hand, are rigid enough to take the wind loads and transfer the window loads down to the slab.” The resiliency of the tower is further strengthened by a heavy central core that allows for exterior pieces to move independently of another during seismic events. For the longterm maintenance of the facade (specifically window washing at great heights) Studio Gang and Heintges incorporated a number of intermittent stabilization anchors across the bay units. In collaboration with building maintenance consultant CS Caulkins and cleaning device fabricator Sky Rider, the design team developed a custom platform capable of being lifted between the bays by integrated attachment points. The project broke ground in late 2017 and topped out in mid-2019; Permasteelisa handled the fabrication and installation of the facade panels and typically fitted out each floor in four days, completing the job at the tail end of 2019. The bays were fastened directly to the slab edge from within the building, a measure that, along with the division of spandrel and infill, reduced the use of a crane on-site and in turn lessened energy consumption and neighborhood disruptions stemming from site logistics. “Three-dimensional aluminum spandrels cover the slab edge and are anchored to the post-tensioned slab with steel embeds that extend vertically,” continued the Studio Gang design team. “Behind the aluminum panels are stiffeners that resist wind loads, reduce deflections, and control flatness. In order to realize the steps between bay geometry variations, there is always a horizontal portion of the panel which either faces up as a sill condition or down as a soffit condition.” Studio Gang principal Steve Wiesenthal and Heintges senior principal Karen Brandt will present MIRA Tower at Facades+ San Francisco on January 31 as part of the “Twists and Stacks: Assembly Innovations” panel.
Brought to you with support fromThe Museum Boijmans Van Beuningen (MBVB), located in Rotterdam's 10-acre Museumpark, is receiving a striking new addition designed by MVRDV. The Depot will house up to 125,000 of the museum's artworks not currently used for exhibitions, with over 70,000 of the pieces being made accessible to the public in a semi-curated format. In response to the site and the functional requirements of the project, Depot's spherical concrete shell has been clad with over 1,500 curved mirrored glass panels. For MVRDV, the location of the seven-story archive drove the decision to use mirror glass for the facade. "The project is situated in a piece of parkland between many cultural and medical institutions, so we did not want to turn our back to any of the neighbors, we wanted to visually enlarge the park," said MVRDV associate architect Arjen Ketting. "A piece of the park has been sacrificed to make space for this building, we visually reintroduce the setting in the facade." This effect is maximized by The Depot's circular massing which allows passing pedestrian to see around the corner of the structure towards the park's greater landscape.
concrete sphere that cantilevers over 30 feet in every direction. At its thickest, the sphere is one-and-a-half-feet in section—a built-in anti-burglary measure—and is punctured by just a handful of window openings to prevent sunlight from reaching the interior. Brackets were anchored into the structure during the concrete pour, and are further supplemented by a secondary network of small black frames; Rotterdam's municipal code requires secondary safety measures for facade cladding. Installation of the mirrored panels began in April 2019 and are arranged into 26 horizontal layers consisting of 64 identical panels, with each layer conforming to the curvature of the concrete shell. Prior to fabrication, the design team digitally unfolded the sphere's surface into a two-dimensional format inlaid with the cutting pattern, which was in turn exported to the manufacturer. Each panel consists of two layers of glass separated by multiple layers of reflective foils, which were curved together during the fabrication process. A layer of insulation produced by Kingspan backs the panels and facade installer Sorba incised the membrane using a 3D model of the supporting brackets to reduce thermal bridging. Although the bulk of the mirrored panels are subject to the same treatment, there are certain segments that correspond to nearby structures. For example, a significant block of the eastern elevation is composed of a less reflective coating to guard the privacy of patients found at the adjacent Erasmus Medical Center. Additionally, mirrored glass panels abutting windows are treated to transition to those transparent moments. The project is expected to be completed in Spring 2020 and will open in 2021.Depot broke ground in 2017 and rises from an approximately 22,000-square-foot concrete foundation that supports a seven-story, poured
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 fromWith a permanent art collection of approximately 3,500 pieces hailing from the 20th and 21st centuries, the Jordan Schnitzer Museum of Art at Washington State University is arguably the most prestigious curatorial institution in Pullman, Washington, and joins a string of art museums founded by the Schnitzer family across the Pacific Northwest. The project opened in 2018 and was designed by Seattle's Olson Kundig, who stamped their presence within the campus with a bold crimson facade of mirrored glass panels. The museum consists of two volumes encompassing a total of 16,000-square-feet. Visitors arrive through an entry built of glass-and-metal casement windows that can be opened in a similar fashion to a garage door. The primary glass volume houses the museum's gallery spaces and is lifted off the ground by an arcade of pilotis and, in some respects, resembles a hovering cube. "A key design challenge was balancing the museum's dual needs for transparency and security," said Olson Kundig design principal Jim Olson. "The answer is a design that consists of two distinct parts: The first serves as an informal entry to the museum and the second space, the "crimson cube," is a climate-controlled space that houses the formal galleries and is enveloped by the crimson facade."
Facades+ Seattle on December 6.Steinfort Glas, a manufacturer based in the Netherlands, produced the mirrored glass facade panels in three different dimensions which function as a relatively conventional rainscreen. The facade's composition achieves a patterned effect through alternating courses of square panels, measuring 3'-4" by 3'-6", and rectangular panels, measuring 3'-4" by 1'-8". The horizontality of each elevation is broken up by steps of larger square panels that are roughly double in size at 6'-6" by 7'-0". "I wanted the museum to have a highly reflective facade as a means of weaving it into its context," continued Olson. "While appearing rather solid and uniform from afar, the reflective crimson cube rewards viewers upon closer inspection, much like the artworks housed within." The effect is achieved through the placement of colored interlayer glass between the mirrored glass panels. The installation of the rainscreen was fairly straightforward and was handled by Hoffman Construction Company, a contracting firm based in the Pacific Northwest. A mounting clip adheres to the back of each individual glass panel, which is subsequently attached to an aluminum rainscreen system produced by Hunter Douglas. The rainscreen system allowed for minor adjustments on site via screws set through the panel joints.

Brought to you with support fromThe Safdie Architects–designed Jewel Changi Airport is a 144,000-square-foot toroidal-shaped glass-and-steel pavilion looping around the world’s tallest indoor waterfall. After four years of construction, the $1.3 billion project opened its doors in April 2019 as a bid to deliver a “paradise garden” amid the cacophony of Singapore’s largest airport. The structural system of the canopy is based on a highly complex stick-and-node mesh fabricated with over 50,000 distinct components assembled piece by piece on-site. The roof spans approximately 675 feet at its longest point and 510 feet at its widest. In total, the steel mesh weighs a colossal 6,000 tons.
Low-E glass, the project is slated to receive a platinum rating from Singapore’s GreenMark program. Although the mechanics of the project are remarkably complex, Safdie Architects developed a design-to-construction methodology to ensure the timely completion of the pavilion. “The entire system, including glass panels, steel members, and the custom-shaped solid steel nodes, was fabricated directly from the design team’s computer model by CNC robots,” said Lubin. “The components were produced off-site and then shipped to Singapore in containers. Special labels with scan codes were used on all the components to assist in locating their final position in the building.” The centrally located Rainwater Vortex, the massive waterfall around an oculus approximately 33 feet in diameter, is the product of collaboration with BuroHappold Engineering and water-feature design firm WET Design. The oculus is topped with an ETFE cushion while a custom-designed circular valve controls water flow between a narrow gap in the glass facade’s surface.From above, the pavilion’s layout looks symmetrical, with many identical glass panels. This is not the case. “The design of the roof is a single-layer add-on system composed of 9,000 custom cut—no two panels are the same—double-glazed panels positioned over the triangulated steel diagrid structure,” said Safdie Architects principal Jaron Lubin. “The double-glazed panel sizes were determined to a maximum dimension of 8.5 feet measured diagonally, which was the size found commonly among several major suppliers.” The project is wrapped with Vitro Architectural Glass’s Low-E Solarban glass, while Vitro’s high-visibility Starphire Ultra-Clear is used for the interior’s pedestrian bridges.
