"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.”
In 2006, the 28th St. YMCA was added to the City of Los Angeles Historic-Cultural Monuments List, and in 2009 it was added to the National Park Service’s National Register of Historic Places.In 1926, just three years after becoming the first African-American member of the American Institute of Architects (AIA), Paul R. Williams designed a landmark YMCA building on 28th Street in Los Angeles. Nearly ninety years later, the building has been restored, and transformed, into a modern multi-family housing complex. Koning Eizenberg Architects (KEA) worked on the project for Jim Bonner, FAIA, architect and executive director of the nonprofit affordable housing organization Clifford Beers Housing. The architects restored the historic 52-unit building, reorganizing the layout into 24 studio apartments, and constructed a new 5-story, 25 studio apartment building next door. The project features a perforated metal screen scrim wall, an integrated photovoltaic panel wall, restored historic stone work. and a shared roof deck that programmatically connects the historic building with it’s modern neighbor. There were two very different projects involved: a substantial restoration and a 5-story new infill construction building. Brian Lane, Managing Principal at KEA says these two projects were “married at the hip”: “We were digitally analyzing Paul Williams’ work on top of crafting our own work.” The architects carefully looked at shadow lines to understand the restored, cast-stone balcony and other components, generating drawings from a careful analysis from historic photographs, looking at shadow lines to understand profiled depths of the historic work. This commitment to digital analysis is most noticeably exploited on a new perforated metal scrim wall, visually buffering the apartment buildings’ circulation system from the sidewalk. The patterning and tabbing of the aluminum metal panels are derived from digitally-controlled abstractions of historic ornamentation found on Williams’ building. In addition to the two-dimensional surface treatment of the aluminum, the panels are assembled on a sub-frame that incrementally rotates outward to provide views of nearby downtown Los Angeles. Julie Eizenberg, Founding Principal of KEA, says that this move creates an effect that is “less rigid,” and “loosens where things begin and end.” The wall system is the result of a collaborative and iterative design process with LA-based C.R. Laurence who, among other things, fabricated the panels. KEA exploited design opportunities of die-cut metal fabrication after discovering a significant cost savings over newer water jet-cutting technology. This included experimentation with the perforation process: various radii were tested, and they developed a “hanging chad” perforation style that cuts and bends the metal at a controlled 37.5 degree angle. The architect’s iterative process during the design phase of the metal screen wall included studies of numerous digitally abstracted patterns, laser-cut study models in chipboard, and mock-ups of the panels. By selectively controlling which perforations remain connected to the panel, a secondary pattern becomes visible in the panel. Lane says there was significant value brought to the project through this low cost fabrication method: “We got a real richness and depth to the panel in a very affordable way.” One of the successes of the screen is the dynamic visual quality of the screen through various lighting conditions. Sunlight is reflected off of the perforated screen during the day, while a soft backlit glow is emitted through perforations during the evenings. On the south facade of the building, a “rainscreen” made of jet black photovoltaic panels is set one foot off of the stark white stucco building facade. While some efficiency was lost by orienting the panels in a vertical array, locating the panels on the facade was done out of necessity. With the rooftop area taken up by various building systems, the south facade became an opportunity to integrate renewable energy features. In the spirit of this “low-tech/high-value” type of project, the PV array helps to block direct gain, while promoting air circulation behind the assembly. Architecturally, the project has been celebrated for it’s novel organization of building systems, its “low-tech” approach to adding value to standard building components, and its dialog between old and new (namely its registering of a digitally manipulated image of historic architectural ornamentation prominently on a primary facade). Outweighing the architectural innovations are the social and cultural benefits to the design, which re-establishes this building’s role as an important cultural community resource by bringing living quarters in compliance with contemporary standards and offers a sense of dignity to low income housing residents and staff.
Unbroken bands of window walls sit beyond an exterior concrete structural frame.Completed earlier this year, a new market rate rental building on Manhattan’s Upper West Side by Handel Architects features a striking exposed cast-in-place concrete diagrid “exoskeleton” structure. The system is designed in response to required zoning code setbacks that restrict building area to a mere 35’ wide at times. The project, named after it’s address at 170 Amsterdam, is located two blocks north of Lincoln Center, situated between two greenspaces – Central Park and the Lincoln Tower superblock – via 68th Street. The lobby is a prominent glassy space containing a mix of community programs, formally and programmatically connecting the two sides of the building together, while abstracted tree-like columns punctuate the building envelope. Frank Fusaro, Partner at Handel Architects, says the use of exposed architectural concrete is a contextual response to its location between the muscular buildings of Lower Amsterdam, where Lincoln Center resides, and the heaviness of classic Upper West Side apartment buildings. “LaGuardia High Schools exposed concrete, MLK School’s corten metal and glass skin wrapped around an opaque core, and the heavily ornate Beaux-Arts exterior of the Dorilton with its quoining, ironwork, brackets, cartouches, oriels and other details all share something in common: these are tough, robust and bold buildings.” Aside from the contextual benefits to exposing a concrete system, the architects noted several benefits to a structural exoskeleton system, contributing to the client’s full support from nearly the beginning of the project. The most significant benefits to the building envelope design were seen when interior floor area was able to be maximized. The structural system of the building resembles a shell structure, achieving high stiffness from an exterior diagrid of columns tied together with repetitive structural floor slabs. This stiffness allows for no shear walls to be required in the core of the building and relatively few interior columns. By moving the columns to the outside of the building, the city’s zoning department allowed for the floor area of the building to be measured to the face of the window wall, rather than the face of the structure. This allowed the architects to add an entire extra floor of program to the building. Additionally, the depth of the facade assembly acts as a brise soleil, passively helping to manage a less-than-ideal solar orientation (unavoidable due to the city grid and buildable area on site). Beyond the columns, a continuous band of window units, spanning from floor to ceiling, establishes the building’s thermal envelope. The windows feature a high performance low e coating to allow for high levels of transparency without sacrificing solar performance. Fusaro says the unbroken line of windows in the apartment units was essential: “The studios are sized just over 400 square feet, so having an exterior wall of glass makes the units feel much larger.” An extremely dense mix of concrete allows for the smooth finish and eliminates voids. The use of less rebar permits a pump tube to be placed in the column and minimizes vibration. Slag was added to the mix to make the color of the concrete more like limestone. Installation of the building envelope after the concrete was poured occurred surprisingly quickly, at a rate of about one floor per week, adding value to the system. The design of the diagrid was optimized to reduce the quantity of fabricating costly “X” forms by shifting the grid on a diagonal axis. The success of 170 Amsterdam has led Handel Architects to further work with exposed architectural cast in place concrete. Most notably, in the Upper West Side, another market rate rental building is under construction currently. For Fusaro, the elegance of exposed concrete is activated with an underlying connection to nature: “I love the organic nature of concrete, you can add or subtract a little of this or that and make it into something entirely different.” Handel Architects: Partner in Charge/Design Principal; Frank Fusaro Project Manager; Honyi Wang Design Team; Alan Noah-Navarro, Elga Killinger, Shridhuli Solanki, Rinaldo Perez, Ren Zhong Huang, Jessica Kuo, Jordan Young, Shujian Jian, Hong Min Kim, Ade Herkarisma, Ana Untiveros-Ferrel
