Construction underway on SO-IL–designed UC Davis Art Museum

UC Davis is set to open the Jan Shrem and Maria Manetti Shrem Museum of Art to the public on November 13. After choosing SO-IL to design its on-campus museum in 2013, the school has been hard at work constructing what it envisions as a "hub of creative practice." Working alongside San Francisco-based firm Bohlin Cywinski Jackson and Whiting Turner, the museum features a 50,000-square-foot canopy made from aluminum triangular beams. The canopy is supported by straight and curved glass walls interweaving both open and closed spaces. Its shape, according to SO-IL, represents a "new symbol" for the campus with its natural surroundings of long, green plains making up the sensory landscape of UC Davis. In its designs, SO-IL emphasized the importance of capturing the essence of the California Central Valley. Changes in season and lighting will be reflected from within the museum which will play host to a variety of activities and programs both informal and formal. The inaugural show will feature work from artists Arneson, William T. Wiley, Manuel Neri, Wayne Thiebaud and Ruth Horsting among others. And with the date for its grand opening months away, the Jan Shrem and Maria Manetti Shrem Museum looks set to become a site of interactive and cutting edge learning.

Ingalill Wahlroos-Ritter shares lessons learned through teaching architecture

For Ingalill Wahlroos-Ritter, associate dean at Woodbury University School of Architecture, director of  WUHO Gallery, and co-founder of [WROAD], architectural practice and education are inextricably intertwined. Wahlroos-Ritter, who joins moderator Alexander Korter (CO Architects) and co-presenters Michael Fox (Cal Poly Pomona), Quinyun Ma (USC), and Neil Denari (UCLA) in a panel on "Facade Education: Preparing Future Practitioners for True Performance" at next month's Facades+ LA conference, first taught at Cornell University after her work as project architect on the Corning Museum of Glass attracted the school's attention. That initial seminar, on the innovative use of glass in building envelopes, helped her carve out a professional niche in the field and also led to an appointment at Yale. At the time, recalled Wahlroos-Ritter, Yale did not offer courses like hers—neither classes on glass, specifically, nor on the intersection of architecture and engineering more generally. "That has changed a lot, [especially] when I think back on when I went to school," she said. The contemporary accreditation process, for one thing, "has elevated the need for systems integration," explained Wahlroos-Ritter. While in the past it had not been unusual for students and faculty from other disciplines to consult on student work, she said, "to rely on engineers to complete a project is new." Her students' relationship to technology like the performance simulation platform Autodesk Ecotect Analysis has also evolved since Wahlroos-Ritter began teaching. "Students are conversant with Ecotect as part of learning BIM," said Wahlroos-Ritter. "That's something I'm seeing more and more in curricula." Meanwhile, students gain hands-on experience in fabrication by building mock-ups of building envelope components. "I think in some ways the academy is leading that part of the conversation," said Wahlroos-Ritter. "Students are learning tools that aren't necessarily part of the trade. Many senior architects don't have the skills these students do." Wahlroos-Ritter relishes her job molding young minds. "For me, one of the exciting moments is the epiphany where students begin to see systems as an intrinsic part of design" rather than something to consider as a postscript, she said. "I talk about Louis Sullivan a lot. He considered the building a living, breathing organism—then everybody forgot about it, of course. I think there's a renewed appreciation for the role building systems can have in the perceptual narrative of a building." Catch up with Wahlroos-Ritter and other facade educators, designers, fabricators, builders, and researchers at Facades+ LA January 28–29. Register today on the conference website.

Are glass skyscrapers still the way forward?

In the wake of a slew of criticisms on numerous glass skyscrapers' over-reflective properties, some architects and critics are asking if it's time to reassess our view on using glass facades in the future. Contemporary architecture today is at a crossroads: Do we continue to enamor the structures that reach up into the sky in a display of corporate might with reflective sheaths of glass? Take advantage of the new technology that is allowing the sun to power these buildings? Or do we take a step back and re-evaluate our position on the all-glass facade altogether? Fred A. Bernstein of the Architectural Record laments that today the "relentless repetition of glass facades leads to a numbing sameness." "Is that a building?" said a designer to Bernstein , "I thought it was a pavilion for a plexiglass convention." It's no surprise that the person, who was passing by Fumihiko Maki's creation at 51 Astor Place, feels disillusioned. At one end of the spectrum, you have cities like Bath in England where such glass behemoths are nowhere to be found. You are surrounded by the Georgian works of John Palmer, who's Lansdown Crescent, despite its scale, is not overwhelming. At the other end, you have cities like Hong Kong and Shanghai, which are filled with an unprecedented amount of glass high-rise structures, their facades lost in the sky with light bouncing off one another. Where then, do we draw the line? With modern skyscrapers being the architectural product of an ever changing, neo-liberalist, globalization obsessed corporate society, such a line may even be impossible to draw. The case for glass—to pardon the pun—is clear. For companies, having floor to ceiling windows helps break down the stratified hierarchy that was once commonplace in such office buildings by giving all employees, not just the boss, a panoramic view. When used effectively, an elegant glass facade can convey honesty and open-mindedness and even perhaps financial transparency. This may be why the style is so popular amongst financial firms, despite the fact this isn't always the case. Developers are also under pressure to maximize space. Having a thin skin such as glass is an easy solution that enables the architect to sell the building's space as good value for money. Plus, the advancement of photovoltaic cells now means that they can be installed as windows, further advocating the facade style as an economically viable asset. PV company SolarWindow, which specializes in PV-based window solutions claims that when installed on four sides of a 50-story building, 1.3 gigawatt-hours of energy can be generated. Architect Ken Shuttleworth however, has different ideas. Despite being part of the team behind the glass clad Swiss Rae building in London, he has since done a U-turn by stating that he is "rethinking" everything he as done in the last 40 years. Shuttleworth's voice is echoed by many in what is an emerging discourse on the glass structures that run the risk of becoming the scourge of the skyline. "We need to be much more responsible in terms of the way we shade our buildings and the way we thermally think about our buildings," he told the BBC last year. The only thing that appears to be halting the perpetual rise of the glass facade in the United States is a shortage in the material. Failure of the market to produce however, has not stopped developers, who according to WSJ’s Robbie Whelan, have now delved into the glass manufacturing industry. Developer, Related Cos has even gone so far as to take production methods into its own hands—building its own glass factory to create the largest private development in American history. Bruce Beal Jr., Related’s president chose to embark on the endeavor for a handful of skyscrapers and apartments on Manhattan’s West Side as part of the Hudson Yards scheme. Across the Atlantic, the trade association "Glass for Europe" is understandably keen to dismiss the growing concern about the once ubiquitous glass facade and advocate the fact that glass is fully recyclable. Pressure from trade unions isn't enough it seems to sway architecture critic Tom Dyckhoff who, like Shuttleworth, isn't a fan of the glass skyscraper. Speaking to the BBC he said, "as someone who spends their entire life staring at buildings, I am a bit bored by the glass box. They were radical in the 1920s and now they are just cliches, expensive ones at that," he said. "Now we are having to be more thoughtful about how and where we use glass. Maybe architects will become more inventive in how they use windows, instead of plastering them across whole facades." Technological advancements may be the only way this question will truly be answered, but for now, money talks and that appears to be what governs the modern architectural style today.

Who needs Paris? Chinese copycat culture strikes again with I.M. Pei’s Louvre

China is no stranger to unashamedly ripping off landmark Western structures—the country has replicas of the Eiffel Tower and several renditions of the White House. However, this time they have copied one of their own architects, I. M. Pei, with a 1:1 duplicate of the Louvre in a Shijiazhuang theme park. The latest addition to the country's collection of replica Parisian architecture lies among overgrown shrubs and unkempt grass in an obscure amusement park in Hebei province. Perhaps unsurprisingly, it sits adjacent to an ancient Egyptian Sphynx. China has already created "Little Paris" in Yuhang, Hangzhou, Zhejiang (East China), which features more mock-Parisian style architecture replete with Tower de Eiffel (though not the real one, obviously). Is this latest piece of "mockitecture" a tipping point or a simply one of more to come?

NBBJ’s New Orleans hospital embodies resilience

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."

KVA Brings Digital Brick to Harvard

Old and new technologies combine in renovated anthropology building.

Tasked with transforming Harvard's 1971 Tozzer Library into a new home for the university's Anthropology Department, Kennedy & Violich Architecture (KVA) faced a unique set of challenges. In addition to balancing the desire for a distinct architectural identity with the building's literal and metaphorical connection to adjacent structures including Peabody Museum, the architects had to accommodate an expanded program within the old library's footprint and structure. As for Tozzer Library's facade, a mold problem and poor environmental performance meant that preserving the brick exterior was never an option. "It's a generic problem of envelopes from buildings that aren't that old, yet can't stand up to contemporary needs," said principal Sheila Kennedy. "What are you going to do with those buildings? The bold approach here was, 'we're going to build on [the existing] value." By stripping Tozzer Library down to its steel and concrete-slab bones, adding space under a two-story copper roof, and wrapping the exterior in a parametrically-designed brick skin, KVA seamlessly negotiated between Harvard's storied past and the mandates of a 21st-century curriculum. Both Kennedy and founding principal J. Frano Violich are quick to dismiss the notion that the problems with the 1971 building, designed by Boston firm Johnson, Hotvedt and Associates, were anything other than a product of their times. "Attitudes toward energy consumption were very different at the time," said Violich. "[Tozzer Library] was built by intelligent people, but everyone's understanding was different from today." In contrast, he said, for the new Tozzer Anthropology Building, "everyone was on top of every [LEED] point." (The project achieved LEED Gold.) KVA began by substituting 6-inch wall studs for the original 2 1/2-inch studs, making way for improved air circulation and insulation. In addition, they eliminated the potential for mold growth by increasing the air gap between the outside sheeting and the back of the brick veneer from 3/4 inches to 2 inches. With the mechanics of the exterior walls in place, "the challenge, aesthetically, was how do we get a sense of both thickness and thinness in the veneer?" said Violich. Luckily, the question of how to breathe new life into flat surfaces was nothing new for the architects. "At KVA we've been very interested in how one designs with contemporary wall systems, with materials that are thin," explained Kennedy. "How do we express their thinness, but by architectural means and devices give them an architectural thickness, manipulate them formally so there can be a game of thin and thick?" In the case of Tozzer Anthropology Building, the answer was a new entrance pavilion with a three-dimensional brick pattern meant to "seem like carved thick brick—like an archeological find," said Kennedy. Drawing upon their early experiments with digital brick, including those at the University of Pennsylvania Law School building, the designers used parametric design software to tie each brick unit to the building's overall form. "As we manipulated the physical form in 3D, we could see various brick patterns that could develop," explained Kennedy. "It was a hybrid of low-tech and high-tech," she said of the process of zeroing in on corbeling, a brick-stacking technique that allows for overhanging layers. The digitally-derived corbeled texture complemented the depth of ornament found elsewhere around Harvard's campus. "We didn't want to make something that was arbitrary and ornamental, but something that was authentic to our time," said Kennedy. To arrive at a final design for the multi-story entrance wall, the architects again combined cutting-edge technology with traditional expertise. "The actual pattern was achieved through physical experimentation," explained Kennedy. "We did a lot of dry stack work with local masons: We would take the designs out of the computer, then pass them to the masons to test. That was a really fun part of the process." KVA then took what they learned from their real-life experiments back into the virtual world, adjusting the digital design accordingly.

Even the flat facades appear unlike typical brick walls, thanks largely to an unusual window arrangement. "When you're looking at the windows, you're not looking at traditional punch windows, or a strip window with a long relieving angle," said Violich. Rather, the windows are shifted to conceal the vertical control joints in the brick. "That helps defuse the veneer quality that brick sometimes brings on," he explained. The floor-to-floor windows further confound expectations by concealing the plenum and—because they are frameless, and punch out rather than in—appearing as much like light monitors as the actual skylights cut into the building's roofline. Tozzer Anthropology Building's recycled-content copper roof completes the dialogue between thick and thin established on the brick facades. "We worked hard in the massing of the design to give a twist to the building," said Kennedy. "That could really only happen in the two new floors." KVA textured the copper roof with vertical standing seams, again using parametric software to arrange different panel types in a corduroy-like pattern. "A lot of times people think advanced facades are super technical, but we can get lost in the technology and why we're using it," observed Kennedy. "[This project] is a good combination of an aesthetic agenda, an architectural agenda, and a technical agenda." For KVA, Tozzer Anthropology Building represents more than just a repurposed campus building. Rather, it offers a provocative answer to one of today's most pressing questions: how to rectify an inherited aesthetic preference for glass with the current push for improved energy efficiency. "Everybody loves glass—we love transparency in architecture," said Kennedy. "But as we move on in our energy transition, we're going to have to develop new ideas about mass and opacity. How can we go back to a pre-modern time, but create something that is contemporary?"

Hord Coplan Macht Pushes Performance at CSU

Ultra efficient curtain wall system marries transparency and sustainability.

For some institutions, building "sustainably" means doing the bare minimum—checking the boxes of government or in-house requirements and then moving on. Such was not the case at Colorado State University, where campus officials aspired to a higher standard for the new Suzanne and Walter Scott, Jr. Bioengineering Building. Though mandated by state law to achieve LEED Gold on new construction, the dean urged the architects—design architect RATIO Architects and architect of record Hord Coplan Macht (previously SLATERPAULL)—to aim for Platinum. At the same time, school authorities placed an extra emphasis on a tight envelope, having had difficulty maintaining pressurization in another recently-constructed facility. Thanks to a combination of an ultra-efficient curtain wall system, spray foam insulation, and exterior and interior sunshades, the designers exceeded the client's performance expectations without sacrificing the program's focus on visibility and connectivity. The ultimate goal of achieving LEED Platinum directly shaped the facade of the classroom and office building. "[The dean] wanted to get to Platinum," recalled Hord Coplan Macht's Jennifer Cordes. "We knew the only way to get there was if we had a significant building envelope designed to add photovoltaics." The PV panels themselves would have to wait, due to budget constraints. In the meantime, Hord Coplan Macht focused on two other challenges: the desire to prevent any loss of pressurization; and the need to rectify the design architect's vision of a glass box with the reality of the Colorado climate. "When we added these issues together, we had to get creative with the building envelope," said Cordes, who also acknowledged the role local municipal rebates played in incentivizing a high-performance design. The design concept for the Suzanne and Walter Scott, Jr. Building, said Cordes, "was to create the space in between. The space between the research laboratories and the student classrooms was really where the students were going to learn from the researchers." The architects arranged the labs along the north side of the building; faculty offices and teaching spaces line the south elevation. The programmatic separation allowed them to sequester the two components' mechanical systems—a boon to efficiency—and to carve the center of the building into a naturally-ventilated three-story atrium that is a perfect space for casual interactions among students, faculty, and staff.

Elsewhere, the focus on connecting students with faculty and researchers is materialized in large expanses of glass. Hord Coplan Macht's principal challenge was to rectify the emphasis on transparency with the mandate to minimize thermal gain. "We started to look at the window to wall ratio," recalled Cordes. "Our first [number] was outrageous. [So we looked] at how we could insulate a curtain wall system and get an R-value of 20 even within that." The solution, which the architects developed in concert with Kawneer, involved back-panning, adding polyiso behind all the spandrel glass to effectively decrease the window to wall ratio. They then added a sheet metal back-panning system inside the curtain wall frame for vapor barrier, plus insulation and GWB. Large panes of stone backed with spray foam insulation provided additional energy savings. "Spray foam insulation is very cost-effective, and you get a high R-value per inch," explained Cordes. "It allowed us to get some significant walls into our system." On the vulnerable south facade, the architects deployed both external and internal sunshades. On the exterior, an integrated sunscreen helps cut back on solar gain. On the interior, the designers sloped the ceilings to help bounce light into the space. The internal light louvers they used, which Cordes compares to "good-looking mini blinds," are "pretty impressive and work really well," she said. The interior shading system "managed the glare and also increased the daylighting, pushing light deeper into the space." All of the exterior glass carries a low-e coating, but the architects chose a higher visibility glass for use on the south facade, to further enhance daylighting. Installing the thermally broken Kawneer 1600 curtain wall system proved trickier than Hord Coplan Macht had anticipated, said Cordes, in part because the contractors—working during the winter—installed the back panning from the inside out, rather than the reverse. But the extra coordination was well worth it, as the project's LEED scores and post-occupancy energy and water use data have demonstrated. "With the caveat that the building is being used a little more than was projected in the model, it's performing better" than expected, said Hord Coplan Macht's Ara Massey. "Per the facilities manager, it's one of the best performing buildings on campus." For Cordes, no reward could be greater. "I think the one [thing] we're most proud of is that it's performing so well," she said.

Brooks + Scarpa’s Double-Skinned Research Center

Perforated steel and translucent glass balance privacy and pop.

For their Center for Manufacturing Innovation (CMI) in Monterrey, Mexico, Metalsa, a global manufacturing firm that specializes in automobile and truck chassis, did not want just another factory. Rather, the laboratory and testing facility, located in a state-sponsored research park adjacent to the Monterrey airport, was to be a "showpiece," explained Brooks + Scarpa Architects principal Lawrence Scarpa, "not just for their clients but from a work environment point of view, and a sustainability point of view." Despite the many challenges inherent to building across the United States-Mexico border, the Los Angeles architects succeeded in delivering a LEED Platinum design wrapped in a striking double skin of translucent glass and perforated steel panels. The facility's uneven sawtooth profile is the product of both historical and contextual references. "They are an industrial company, and I always loved the old warehouses with the north-facing clerestories, designed back when there was no electric lighting," recalled Scarpa. "That was what I was thinking about before I even went to the site." His first visit to Monterrey confirmed his instinct. "The mountains there are really sharp and jagged like that—it was an immediate concept for the building," said Scarpa. Like their 19th-century antecedents, moreover, the clerestories provide daylight and allow hot air to accumulate high above the inhabited spaces, thus reducing reliance on artificial lighting and cooling. The resulting form had one major drawback, however. "The issue we were faced with was that the primary way you enter the building is from the west, so we would have a broad face in the worst possible thermal position," said Scarpa. To solve the problem of solar gain without sacrificing the sawtooth roofline, Brooks + Scarpa implemented a double skin with an outer layer composed of perforated steel panels. With a wraparound sunscreen in place, explained Scarpa, "we could have a translucent skin behind it, but could modulate light and heat gain."

Several factors influenced the perforation pattern on the outer skin. It began as an abstraction of Metalsa's corporate identity, said Scarpa, but evolved to respond to programmatic requirements. Perforations of different sizes and densities reflect the need for more or less privacy. Areas related to proprietary research and development are more opaque, while the office spaces cantilevered over the transparent northwest entrance benefit from the additional daylighting allowed by broader perforations. CMI's translucent inner skin of fluted glass refracts light, preventing glare from interfering with computer-based work. To prevent the occupants from feeling trapped in a windowless box, the architects carefully modulated the distance between the envelope's two layers. "When you're on the interior, it doesn't just look like a blank wall," said Scarpa. "When you're on the inside, you can't see through it, but you can see shadows move on the translucent surface." Designing for an out-of-country client is bound to produce hiccups, and the Metalsa project was no exception. For instance, Brooks + Scarpa had initially imagined that the auto giants would fabricate the perforated metal skin in-house, but turned to another supplier when disrupting the company's manufacturing flow proved cost-prohibitive. The architects nevertheless made the best of the situation, streamlining their vision to fit the situation at hand. "The technology that was available to us in Mexico is not overly sophisticated, so from the get-go we decided to take a more simplistic approach, utilizing a multi-layered skin," said Scarpa. "It was easy to construct, and it's not difficult to understand."

nARCHITECTS reveals Café Pavilion for Cleveland’s revamped Public Square

New renderings for one of the largest public space projects in the Midwest have been revealed, showing a new 2,500-square-foot “Café Pavilion” in Cleveland's Public Square. Brooklyn's nARCHITECTS designed the structure, which appears in renderings via project lead James Corner Field Operations. It will be the only structure on the 10-acre square, besides the existing Soldiers and Sailors' Civil War monument. Cleveland's Public Square is the subject of a major overhaul led by designers and engineers at at James Corner Field Operations, Cleveland's own LAND Studio and Westlake Reed Leskosky, as well as transportation consulting firm Nelson/Nygaard. The project aims to remake the splintered downtown park into a pedestrian-friendly destination that will catalyze development in the area. The cafe structure will serve as a billboard for that transformation. A curated “art wall” faces out, beckoning pedestrians passing by Terminal Tower and acting as the primary entrance to Public Square. Stainless steel panels and tall glass windows broadcast modernity on the building's other faces. “As a building with no back, each side of the Café Pavilion is meant to be a unique ‘front’ façade that offers a different experience,” reads the project description. The cafe, currently under construction, is expected to open in 2016.
