"The copper woven mesh opens like a curtain over the city. It unfolds like a filter in front of a fully glazed facade. It shows off the facility while protecting it."ARC.AME Urban Architects have designed a new School of Art in the center of Calais, a northern port city in France. Recently the town has been notable for a growing refugee population which has attempted to migrate to England by means of the Eurotunnel transit tunnel beneath the English Channel and ferries. The architects say this project exists as a symbol of the revival of the city center: “the powerful and original architecture of the project had to respect the balance and the scales of the context into which it was embedded.” The school program was designed to be fully public, allowing for freely accessible galleries. A secondary residential program provides 25 apartments, placed like houses on the rooftop. The units are designed as duplexes, each with a south facing terrace. A central courtyard links these residences with the university program. The architects say one of the major challenges at stake in the revitalization of historic city centers, which have been abandoned for the suburbs, is the new lifestyle that a dense mixed-use environment creates. With adjacent buildings literally tied into an existing commercial mall building on the site, demolition was a challenging aspect to the project. The new structure is coordinated to the massing heights of the contextual buildings, however it strongly varies in materiality. A woven copper mesh product from GKD France screens a facade composed primarily of glazing, and formally opens up onto the city as a curtain. The mesh filters daylight, protecting art galleries and equipment from direct exposure. The coloration of the mesh incorporates a high gloss paint to protect the material from its coastal environment. The roof is detailed in a lacquered copper, subtly – nearly invisibly – transitioning to the metal mesh product which rolls over the facade walls. Several mesh configurations were tested to achieve desired lighting results for classroom and studio spaces. The radial section profile allows the product to be incorporated onto the facade as a single piece, without any splicing required. The architects say one of the greatest successes of the project is the qualities this solar shade provides: “We love many aspects of this project; the mesh, the concrete matrix, the central garden, the exhibition hall…but the thing that lived up most to our expectations is the quality of the light which diffuses all across the building and the visual transparencies between the several indoor spaces.”
A total of 149 custom panels cover nearly 11,000 sq. ft. of the facade, providing a passive approach to daylighting, glare reduction, shading, and solar heat gain reduction.The Georgia BioScience Training Center is a signature building with a dual purpose: a high-tech facility supporting research critical to bio-manufacturing that brings identity to Georgia’s growing biosciences industry. The 40,305 sq. ft. building is sited approximately 45 miles due east of Atlanta in Social Circle, "Georgia's Greatest Little Town,” and houses laboratories, classrooms, meeting rooms, and large gathering spaces. The building is organized around a large elliptical courtyard lined with glass walls. “Building planning centered on the idea of a “10 minute marketing tour” as the state will tour thousands of future 'prospect' companies through the facility,” says Nathan Williamson, Associate Principal at Cooper Carry. Williamson says the exterior courtyard doubly serves as a breakout space for large meetings and events, while drawing daylight into the training spaces. “By centralizing this natural amenity and event space, all spaces are energized by daylight while vistas create an open, highly-collaborative environment. The result is a high performance design that evokes the sophistication of 21st century bio-manufacturing.” The most striking feature of the building envelope is a large angular metal mesh veil, suspended off the building by a steel frame. Williamson notes the versatility of the aesthetic properties of the material combined with the performance of the veil as a passive solar shading device brought a significant value to the project: "We infused stainless steel into the exterior design to capture the performance benefits of shading while expressing the connections of the system which enhance the client’s brand of a decidedly hi-tech facility. The mesh is expressed independently from the orthogonal main façade with facets and plane changes to provide a dynamic, crystalline aesthetic with ever changing shadows and reflections that suggest a sense of movement." The BioScience Center’s high precision metal facade assembly is a familiar aesthetic for the high-tech students and visitors of the facility. The metal mesh product, named “Lanier” after nearby Lake Lanier, was developed by Cambridge Architectural as a custom solution specific to this project which has become a showcase for the architectural metal company. "We always like to be involved early in the process of any project and work with the architect once the initial design has been established,” says Matt O’Connell, Director of Operations at Cambridge Architectural. “After initial review and discussions with Cooper Carry about their vision, we conducted 3-D modeling. But the computer only goes so far, so we went through multiple specifications and mock up processes, both small and full size, to provide the right mesh fabric for the job.” The rigid panels are fabricated as trapezoidal shapes to account for the faceted panels. When folded into place, the panels assume an orthogonal ribbon-like patterning. Cambridge developed the rigid mesh to allow for a one-directional bend. The product is suspended in tension off a rigid steel frame that allows the dimensions of the panel to be maximized with fewer intermediate supports. The result is a lightweight (1.28psf) panel with a maximum width of 10 feet, and a maximum length of 100 feet. A unique feature of Lanier is the ability to expand and contract the open area of the mesh, by removing fill wires as the pattern repeats. What results is a quality of lightness in the material - the ability to block direct sunlight while maintaining views from within the building. “We know that architects are seeking flexibility and looking for mesh choices that create a more stimulating visual appearance while providing options for varying degrees of light passage,” said Cambridge National Sales Manager David Zeitlin. “In the case of Lanier, they can even choose to expand the openness of the pattern for a single panel. We call this option Transition.” The material has been used for exterior facades, solar shading, parking garages, and interior screen walls.
High performance and cultural relevance meet in concrete, metal, and steel mesh envelope.For the stakeholders involved in building the new Rev. Avery C. Alexander Academic Research Hospital (also known as University Medical Center, or UMC) in downtown New Orleans, the project was about much more than replacing facilities damaged during Hurricane Katrina. "The grander story is the effort to rebuild New Orleans," recalled NBBJ principal Jose Sama. "There was a lot of emotional attachment to the original hospital, Charity Hospital, and also—rightly so—the pride the community has for the character of the city. Everyone wanted to make sure the project was going to be something that was of New Orleans." In a joint venture with Blitch Knevel Architects, NBBJ rose to the challenge with a design that subtly reflects the city's cultural heritage. The building envelope, a combination of precast concrete, metal panels, high performance glazing, and stainless steel mesh, contributed significantly to both the project's aesthetic aspirations and its performance goals. The overarching concept for UMC, explained Sama, was to "create a performance in place." For the architects, "performance" holds a double meaning. "Performance is embedded in [New Orleans] culture, but this is a more high-level sense of performance," said Sama. "Place," in turn, draws on the city's climate and character. "We looked at various clues in the urban environment and how those could affect the design," said Sama, recalling visits to the hospital's Canal Street neighborhood and the French Quarter. Then, of course, there are the environmental threats made all too clear by the Katrina experience. "We completed [the design] with the understanding that we had to create an envelope that could withstand hurricane-force winds and missile impact," said Sama. "That was an important piece of selecting the glass and the curtain wall system." In fact, most of the damage sustained by Charity Hospital was the result of flooding rather than high winds. As a result, the architects faced a mandate to elevate all critical hospital functions above 22 feet. "We envisioned this as a floating hospital," said Sama. "The notion was that the more public zones, the softer spaces like dining, registration, and the lobbies, would occur at the ground level. Then you move up to an elevated plane of critical services. That way they could function regardless of flooding." The building envelope reflects this programmatic move: The first floor of the central campus structure—the diagnostic and treatment center—is wrapped in a transparent curtain wall with a strong emphasis on the horizontal while the upper, critical floors feature a precast concrete facade. The two other project components, the medical office building and the inpatient towers, offer variations on the theme. The former is clad in an insulated metal panel system, the latter in precast concrete, glass, and stainless steel mesh. A number of subtle gestures connect the hospital exterior to New Orleans' history and culture. One thing Sama noticed on his site visits was that "the notion of the garden is important, and the notion of getting outdoors." With that in mind, the architects created a central entry pavilion "designed such that you have a very pronounced sense of entry created by a porch, or a projecting eave—it almost has the effect of a trellis," said Sama. They also created informal gardens wherever possible. The signature garden, nestled between the towers and the diagnostic center, is water-based, and imagines the seating areas as lily pads floating on a pond. "The idea that here in the middle of New Orleans you find a water-intensive garden was really critical," said Sama. The patient towers, too, embody a strong connection to the outdoors via balconies for patients and staff. Metal scrims in Cambridge Architectural's Mid-Balance architectural mesh simultaneously provide aesthetic interest and fall protection. "We studied what we could do with the scrim," said Sama. "We think we picked just the right scale. It's appropriate for someone sitting on the balcony, but also for someone walking by." The mesh panels produce a "soft veil effect," he observed. "In the morning light, it glistens. The intent was to create a memory of Mardi Gras beads, in terms of color and glistening. People will pick up on that different times of day." Cambridge Architectural contributed to several other elements of the project. Mesh fins in the Scale pattern are attached with a custom cable tensioning system to the upper levels of the patient towers, to provide solar shading. On the parking garage portion, designed by Blitz Knevel Architects, 86 panels of Scale mesh again add both visual impact and fall protection without compromising ventilation. On the south elevation of the garage leading to the UMC helipad, a custom-built shade mesh fin system cuts solar gain and glare. Many of the references embedded in the new UMC hospital—the way in which the towers' orientations recall traditional New Orleans shotgun houses, or the connection between the stainless steel mesh and Mardi Gras beads—are so understated as to operate on almost a subliminal level. But like the city itself, the building comes alive at night, finally, and literally, revealing its true colors. "The building from the outside is very neutral," explained Sama. But thanks to accent colors on the inpatient tower stairs, revealed through translucent glass, plus accent lighting on the bulkheads above, after dark the towers shine, he explained. "The whole point was that at night they would glow with color from within."
