A 48-by-35-by-26-foot public artwork has been installed in the main concourse of the Orange County Convention Center in Orlando, Florida. The work, titled Under Magnitude, is designed by New York architect Marc Fornes and his firm THEVERYMANY as a “curious signal and a place for visual wandering” meant to activate one of the convention center’s main social spaces.
The two-story sculpture—made up of 4,672 ultrathin aluminum strips and 103,723 rivets—is suspended above the concourse floor via steel wires and can be seen at eye level from the mezzanine. The structure follows the laws of what Fornes described as “tangential continuities,” a geometric phenomenon describing how micro-level linear components are utilized to describe macro-scaled, nonlinear geometries. The model dates back to the work of 20th century artist Frei Otto, whose Soap Bubble Model theory postulates the so-called “extensive curvatures” at the foundation of Fornes’ work. Frei was interested in the geometric and structural tension that occurs in surfaces that transfer stresses along their length. Fornes inverts that theory via his notion of “intensive curvatures,” in which digital modeling is used to “maximize double curvature across the project,” rendering dynamic and fully self-supporting forms. The result is a holistic structural system that is defined by a tightly curved and constantly changing surface that is also incredibly strong and composed of thin materials.
The project, developed using Rhino digital modeling software, opened in March 2017. In a video, Fornes said: “Some people start to project their own background onto it. If you come from the sea, some people will read coral. Some people will read flowers. It doesn’t matter [how the viewer interprets the form], but it matters that they engage and that they start to wonder about the structure.”Under Magnitude Orange County Convention Center Orlando, Florida Tel: 407-685-9800 Architects: THEVERYMANY
Scheduled to open later this year, the Interdisciplinary Science and Engineering Complex (ISEC) on Northeastern’s campus is a 220,000-square-foot research complex that provides state-of-the-art infrastructure, fosters collaboration across disciplines, and increases the university’s capacity to hire top faculty and academic leaders. Prominently sited along an axial pedestrian approach within the private Boston-based research university, the design features a curvilinear translucent facade. The project is a showcase for Payette’s Building Science group, which integrates building physics thinking into the design process. The program was initiated over 5 years ago by Andrea Love, Associate Principal at Payette, and has grown to a specialized three-person team. In addition to overseeing all projects produced by the 140-person firm, the group takes on research initiatives. In 2012, Love, who recently spoke at Facades+ Boston, was awarded the AIA Upjohn Grant on “Thermal Performance of Facades,” a research project studying the effects of thermal bridging in 15 recently completed in-house projects. Love told AN that developing an “energy literacy” in the firm is their goal: the outset of all projects begin with “an intelligent starting point, derived from previous research and studies that have been performed.” For ISEC, the role of Love’s Building Science group was to first inform what kind of facade system was appropriate for the complex: Both performatively and aesthetically to maintain the design vision that had won them the project. The team initially thought a double-skin facade would perform best in the cold New England climate, but quickly determined that solar gain from the southwest facing glass facades would need to be managed. A high performance sun shading system was developed through an iterative process between the Building Science group and Payette’s project team, optimizing fin geometry to balance construction and budget constraints with digital analysis tools like Ladybug + Honeybee for Grasshopper. This method of working translated from the formal composition of the fins—their various curvatures, dimensional limits, and on-center spacing—to construction details which acknowledged a desire to simplify the installation process with a high performance agenda that resulted in minimal thermal breaks and the introduction of rubber pads to minimize thermal transfer. Love said the aluminum fins saved cost on multiple fronts, reducing energy usage by over half of what it would have been without the shading devices, and allowing for a more standard building envelope. “This allowed us to have a traditional curtain wall that is straight in the back, then produce curvature with the fin assembly, achieving a complex doubly curved geometry at a relatively affordable cost.” During value engineering, half of the aluminum fins were proposed to be eliminated to save cost. Through energy model analysis, the Building Science group determined proposed fin reductions would actually increase the cost of the project by requiring greater cooling loads. Love says an integrated design process is critical to proving the value of the firm’s work: “If you don't have that integrated design from the beginning, essential design components often get removed because you cannot prove their impact. this was very helpful to maintain the performative aspects of the design, but also the design vision throughout the design process.” Payette worked closely with ARUP and Permasteelisa Group on the development of the custom aluminum fin system. While a few key sections were produced for construction documents, the construction of facade components was largely referenced digitally by sharing Rhino geometry with fabricators who produced construction model geometry. With shell construction complete, the project is scheduled to open in November.
A custom architectural enclosure composed of 200 CNC-milled custom aluminum extrusions.Forming a porous perimeter to a new ballpark at Southwest University Park in El Paso (home to the minor league El Paso Chihuahuas), Ball-Nogues Studio's “Not Whole Fence” project taps into a tradition of monumentally over-scaled public art with an attention to craft and detailing. Capping off the Populous-designed ballpark, the fence installation turns the corner along a busy pedestrian intersection. The public art commission involved design, engineering, and installation in a rapid timeframe – the architects were given less than a year from conceptualization through fabrication. Benjamin Ball, principal in charge at Ball-Nogues Studio, said there was a desire to address the history of the game with the installation. “There’s a mythical history to baseball about kids using knotholes in the fence to sneak views into the game if they didn’t have tickets.” The fence adopts a large scale wood grain patterning, scaling up the dimensions of a picket to form one massive bending surface. Strategically placed “knotholes” in the surface composition allow pedestrians an opportunity to catch a glimpse of the action on the field. “The structural quality of the fence creates a sense of mystery. By allowing mostly partial views of the action inside the ballpark, it calls for the imagination to conjure up the rest of the picture, creating a sense of fantasy and infinite possibilities.” While the design concept evokes a literal image of a wood plank, the detailing of the facade components produce a sophisticated, robust assembly. The architects designed the fence as a system of extrusions serving as both the skin and the structure. Working with Sapa Extrusions, the team designed and produced a custom dye for production of a unique aluminum extrusion for the project, ultimately yielding around 200 repeatable components that bolt together on site. Ball said a lot of design and engineering that went into the individual extrusion. The team designed in fins on the front side, with larger struts on the back side, producing enough structural rigidity to withstand a subtractive CNC milling process. A wood grain patterning is registered in the surface by milling out selective areas of the panels. When viewed frontally, glimpses of the ballpark can be seen, however when viewed obliquely, large struts block openings while providing surface area to reflect a soft glow of daylight. Ball notes interesting similarities to the tectonic assembly of some segments of the US/Mexico border fence, only a quarter mile from the site. "You can't blow anything up to a colossal scale without thinking about Claus Oldenberg," said Ball regarding the literal reading of a picket fence in their fence facade. "We've never used that as a strategy before in our work. This still has to function as a fence, and we still value things like detailing, tectonics, connections. In contrast to Oldenberg's work, we occupy an "unusual gray zone" between architecture and public art.” Ball says his studio is ultimately is interested in craft of building regardless of typology. “We're looking for the right challenges, and the right people to work with. Are they willing to take chances? Do they believe in our process? That could apply to buildings or public art.” CORRECTION: Neal Feay Company was originally omitted from our list of Project Credits.

"It has never looked the same on any two times I have been to site."JCY Architects and Urban Designers have created a student services building on the Australian campus of Edith Cowan University that acknowledges the cultural identity of local Aboriginal community while providing sculptural infrastructure linking the campus community through a series of landscaped environments. The major elements of the building are an elevated concrete podium helping to negotiate a steep grade change, and a perforated aluminum solar shade. The project acts as a web with a central internal vertical spine atrium linked to various programs with a set of interconnected timber clad stairways. An elevated concrete podium navigating a significant grade change is formally derived from fluid dynamics studies of the flow of water through Australian billabong waterways. The podium's folded and sculpted white concrete soffit and faceted columns create their own seductive landscape, 'eroded' and opened up as would be found in nature when stone is sculpted by water. The architects designed the building in a way that makes future conversion to classroom space possible. This was achieved by incorporating “bubbledeck” concrete floor plates. This voided-slab forming system reduces the weight of the slab, increasing efficiency and reducing overall cost. The long span system allows for more slender columns, a generous structural grid spacing of around 30 feet by 30 feet, and a reduction of the shear walls required within the open plan layout. The architects also accounted for the maximum future utility spaces that would be required with a future change of use, which they say required over 30 percent redundant floor area. Embedded within the fabric of the interior and exterior skins are a number of themes which were developed through a collaboration between the architects and ECU’s Cultural Liason Officer from Kurrongkurl Katitjin and the local Noongar community. One outcome is a gold anodized perforated aluminum screen that folds around three upper levels of the building. Patterning is derived from curved, overlapping patterns of the chest feathers of a Carnarby Cockatoo, and creates a layered undulating effect. The perforation of the panels derived from manipulations to photographs of chest feathers from a black cockatoo. Hole diameters correspond to light values on the photograph – the darker the pixels, the larger the openings. Data from the open percentage of each panel was used in shading calculations to comply with Building Code Glazing Performance Criteria. Will Thomson, Principal at JCY, says the major constraints with this shading system were related to costs: “We could have no more than 8 different hole punch diameters to fit the project budget, and once these had been determined they were carefully set-out at 1:1 shop drawing over the panel drawings. They varied between 20-40% open area to meet the ESD requirements.” This aesthetic is introduced to the interior glazing system through a custom ceramic frit pattern and textile design of the carpeting. The fabrication and assembly process included several full size prototypes, which helped to resolve panel geometry. Thomson says the mockups resulted in many fabrication changes to allow for tolerance, movement of dissimilar metals, panel assembly details, material selections, and structural connection details. The anodized finish of the aluminum skin is inspired by the shimmering scales of a butterfly wing. Thomson says the anodized finish consists of a range of colors: “This has created an amazing patina of differing gold panels across large swatches of elevation and added a texture to the facade that would otherwise be lacking. The way the building changes color during the day, across the seasons is always a welcome delight. It has never looked the same on any two times I have been to site since the cladding works have been completed.”
