Artists' housing in downtown Phoenix might (literally) elevate the Airstream

Public design review on the project has yet to start, but it looks like downtown Phoenix’s Roosevelt Row could be getting bohemian-style artists housing courtesy of national firm Shepley Bulfinch. By suspending chrome Airstream trailers within a diamond-shaped scaffolding, developer True North Studio, artist Wayne Rainey, and Shepley Bulfinch hope that the four-story Roosevelt Land Yacht Club will supply up to 30 units of affordable housing for local artists. Rather than acting as a standalone building, the project presents a novel type of urban infill; the Roosevelt Land Yacht Club will wrap around the exterior of an existing corner parking garage and fill in the 15-foot gap between the building and the sidewalk. Each trailer—the Airstreams may have to be replaced with a less iconic model—will feature about 350 square feet of living space. The multilevel steel matrix will be constantly painted over by the artists to create a structure that’s half living space, half piece of art. The diamond motif and airy framing reference both rolling desert dunes as well as the sense of freedom brought on by the open road. Of course, this is all speculative at the moment. True North Studio expects that the design review and permitting process with the city of Phoenix will take approximately six months, and hopes to break ground in 2020. While no rent information has been released yet, making it unclear how affordable the spaces will be, the scheme could still create a new precedent for infill housing if it moves ahead. The Roosevelt Land Yacht Club is part of the much larger, multi-building mixed-use renovation titled Ro2. True North Studio is handling the entire project after being selected through a request for proposal issued by the city of Phoenix, but, as the Phoenix New Times noted, it was also the only developer to submit a proposal.

This Arizona medical school blends into the desert with a folded copper facade

facadeplus_logo1
Brought to you with support from
Located on the northern border of Downtown Phoenix, Arizona, sits a new medical research building for the University of Arizona. The 10-story Phoenix Biomedical Sciences Partnership Building (BSPB), designed by CO Architects, joins their preexisting structure on the Biomedical Campus to combine lecture halls, research facilities, and public functions. The design of the building’s facade is intended to blend into the Arizona desert landscape with folded and perforated copper panels. The building rises immediately adjacent to CO Architects' Health Sciences Education Building, with the tightly packed nature of the campus serving as a passive shading device for both public and interior spaces. Additionally, the building runs along an east-west axis to reduce solar exposure during the morning and afternoon.
  • Facade Manufacturer & Installer Kovach Building Enclosures
  • Architects CO Architects
  • Associate Architects Ayers Saint Gross
  • Contractors DPR Construction Sundt Construction
  • Structural Engineers John A. Martin & Associates
  • Energy & Environmental Design Atelier Ten
  • Location Phoenix, AZ
  • Date of Completion 2017
  • System Copper rainscreen and sunshade
  • Products Custom-fabricated copper panels
For the design of the building's envelope, CO Architects analyzed and incorporated the natural features of the surrounding Sonoran Desert. Specifically, folds within the copper panels are intended to reflect the physical traits of the Saguaro Cactus. The skin of the cactus undulates as a means of self-shading so the successive floors of panels on the facade protrude to mimic geological striations while also shading bands of fenestration below. Notably, the copper skin is located two inches from the structure's thermal barrier, effectively wicking away heat by serving as an enveloping chimney. In total, nearly 4,800 panels weighing approximately 295,000 pounds wrap the building. According to the design team, one of the greatest challenges of the project was creating a semi-standardized cladding that visually remained unique. "How do we create a vision, a geological imprint onto the building," said CO Architects' Principal Arnold Swanborn. "How do we create a pattern that was not repetitious?" To this effect, the design team generated six groups of panel types—each is comprised of four modules of the same height and width. Modules within specific panel types were alternated to display a breadth of visual striations. Kovach Building Enclosures, based out of Arizona, manufactured and installed the facade panels. Remarkably, over 90 percent of the cladding was fabricated with recycled copper—ranging from multi-ton ingots to gauged coils. According to Swanborn, the manufacturer effectively "negotiated between what our dream was, and what was feasible." To this effect, the design team utilized BIM software to generate 3-D models of the panels for Kovach to analyze. Over the course of the nine months, the manufacturer detailed each panel via a brake press, relying on a team of two to operate the machinery.

Waymo's self-driving cars in Arizona elicit violence

Residents of Chandler, Arizona, are waging war against the city’s new fleet of self-driving cars. Distraught locals have slashed tires, pointed guns, and thrown themselves in front of Waymo vehicles in order to prevent them from transporting passengers, according to The Arizona Republic. In April 2017, technology development company Waymo started a trial of self-driving taxis in Phoenix, the first of their kind. This past month, the service continued to expand as it launched its first commercial self-driving car service called Waymo One, where people of the Phoenix metropolitan area can request a driverless car through the simple use of a cell-phone app. Since Waymo vehicles took to the streets some two years ago, 21 rioting incidents have been reported to the police, particularly in Chandler, a suburb of Phoenix. While safety concerns seem to have triggered many of the violent outbursts, other locals see Waymo as a threat to their livelihood. People are worried that technology is going to replace them in the workforce. Taxi drivers across the world, for instance, have fought against the rapid dissemination of Uber and other ride-hailing services. Waymo's current controversy is just the latest in a series of incidents where autonomous vehicles or ride-sharing companies are getting into trouble. Last March, the self-driving car industry as a whole suffered the ultimate backlash when a self-driving Uber SUV mindlessly hit and killed a woman in Tempe, Arizona.

Waymo's self-driving taxi service goes live

Self-driving cars are ever inching closer to feasibility, as the Alphabet-owned company Waymo announced the official rollout of its self-driving taxi service today. The launch of Waymo One in Arizona, although only initially available to research testers from Waymo’s research program, is a milestone that critics thought Waymo wouldn’t be able to reach before the end of 2018. This year was a pretty dour period for real-world autonomous vehicle (AV) testing. Uber drew ire and shut down its self-driving car operations in Arizona after a test vehicle struck and killed a pedestrian crossing the street. Federal regulators from the National Highway Traffic Safety Administration shut down a self-driving school bus program in Florida. And in Chandler, Arizona, just outside of Waymo’s AV testing ground, residents complained that the self-driving cars would regularly stop without warning at a T-shaped intersection and require that the human safety drivers take control. Waymo is starting small with a pool of invite-only riders, but the launch today fulfills a pledge the company had made to get its fleet of AVs on the road before the end of the year. Customers can hail an autonomous vehicle in the Metro Phoenix area through the Waymo ridesharing app in the cities of Tempe, Chandler, Gilbert, and Mesa. Each car will be decked out with touchscreens, where passengers can connect with a Waymo rider support agent to have questions about their trip answered. In-car chaperones will be present during the first phase of Waymo One’s rollout, but moving forward, the company wants to graduate to fully-driverless rides. The early rider program will continue, and test riders will have early access to features that Waymo wants to include in their taxi service. The company is hoping to use the feedback from its Phoenix-area riders to eventually expand the program to other cities and the general public.

Frank Lloyd Wright's David and Gladys Wright House back on the market

It looked like Frank Lloyd Wright’s spiraling David and Gladys House in Phoenix, Arizona, had been saved from the wrecking ball back in June of last year, but a deal to donate the building to the Frank Lloyd Wright School of Architecture has reportedly fallen through. Now the house is back on the market for $13 million, over $10 million more than when it first went up for sale in 2012. After being purchased in 2012 by homebuilder and architecture aficionado Zach Rawling, it appeared that the house, built in 1952, would be restored and put to good use. Rawling donated the building to the Frank Lloyd Wright School of Architecture at Taliesin for use as a learning center and in-situ design studio, which kicked off during the 2017-2018 academic year. Although the school was able to produce videos with several well-known architects at the house and successfully complete the scheduled studios there, funding concerns seem to have scuttled the partnership. In a joint statement released in June of this year, Rawling and the school's dean Aaron Betsky announced that due to conflicting funding obligations and an uncertain timetable, the school and house would part ways.
The relationship between the School and the House is formally manifested in the David Wright House Collaborative Fund, a supporting organization of the Arizona Community Foundation. The principal focus of the David Wright House Collaborative Fund was to develop a vehicle to raise the $7-million endowment on which the pledge of the House for the benefit of the School was conditioned. Over the past year, we have learned that the fundraising timetables of both parties do not lend themselves to a joint campaign.
The original terms of the donation, which required that the school raise $7 million by 2020, proved difficult. Additionally, Phoenix residents reportedly weren’t thrilled over the potential conversion of the house into an educational facility and were worried about the traffic and noise the transformation would bring. Interested in buying a progenitor to the Guggenheim? You can put down your $12.9-million bids here. AN will follow up on this story when updates become available.

Howeler + Yoon and substance are among winners of AIA Small Project Awards

Big ideas start with small changes. This is definitely the case for the 11 outstanding projects that were just honored for their design excellence in small project design as the American Institute of Architects (AIA) just announced its 2018 Small Project Awards winners. The awards are given in three categories: architectural objects or environmental art that cost up to 150,000 in construction (Category 1), small project constructions that cost up to 1,500,000 in construction (Category 2), and projects under 5,000 square feet (Category 3). The theme this year is “Renewal.” Here are a few of the Small Projects award winners: Howeler + Yoon Architecture designed Shadow Play, a hovering canopy formed from triangulated modules. Located in downtown Phoenix, Arizona, Shadow Play is a cluster of shade structures that casts geometric shadows that transform the streetscape and how pedestrians congregate in the public space. The canopy’s design maximizes the shaded area but also allows for apertures that bring breezes underneath, making it an ideal space to sit and relax. substance architecture designed the Principal Riverwalk Pump Station in Iowa, which also received the award. The design includes two objects–a Pump House that responds to the neighboring Café Pavilion with similar materials of black zinc and steel, and a Gate Valve Platform that combines translucent glass atop and a solid concrete base. According to the AIA, “The creation of this facility has literally led to the renewal of Des Moines' Historic District and, in concert with the Café Pavilion, it frames a popular public space along the river.“ Kevin Daly Architects was recognized for a low-cost, low-impact prototype backyard home. The 500 square foot parcel dubbed BI(h)OME has an innovative facade made of a paper honeycomb inside layers of ETFE, making a lightweight but sturdy structure that creates a pleasing aesthetic. The prototype is recyclable and customizable, and aims to serve as a housing option for 500,000 single families in Los Angeles, a city that struggles with a “shelter crisis.” Sawmill, designed by Olson Kundig, is a family retreat standing in the high desert of California. In response to the harsh climate and the remote location, the net-zero home utilizes recycled but durable materials and employs strategies to reduce environmental impact and minimize operating costs. Cutler Anderson Architects’ design of Studio / Bunkhouse blends in with the wooded site in Washington. The 80 square feet compact, multi-purpose toolbox is set at the top of a waterfront bluff and complemented by the jury for the ability to work with limited power-tools within the challenging site. Other winners include Allford Hall Monaghan Morris for The Grand Lake Poolhouse, FXCollaborative for their Chapel at Congregation Kehilath Jeshurun, and Edward Ogosta Architecture’s design of Rear Window House. For the past 15 years, the AIA Small Project Awards program sets out to promote value and design quality in buildings, no matter their size. The complete list of the awarded projects can be seen in the link.

DLR Group converts a former Phoenix jail into sunny offices

DLR Group is currently at work repurposing an existing 1980s-era county jail in Phoenix, Arizona, as a new, state-of-the-art office space owned by Maricopa County. The now-decommissioned jail was originally designed to hold 700 inmates, but its population eventually swelled, incarcerating between 1,200 and 1,500 individuals at a time over the last decade of its life. The jail was decommissioned in the early 2000s and has sat vacant for a decade. After DLR Group’s planned renovations, however, the complex will have new life, and will house six levels of daylit office space and ground-floor community areas.

“The basic approach was to remove everything back to the superstructure and start over,” Larry Smith, principal in charge of DLR Group’s southwest division, said. Smith explained that the 350,000-square-foot structure will be surgically altered in order to absorb the new office functions.

Planned changes include completely removing the structure’s four mezzanine levels and replacing its exit stairs. The existing stairs are located awkwardly within each of the four square-shaped lobes of the complex, impeding open floor plan configurations. They will be demolished and their footprints filled, with new exit stairs to be located at each corner, beyond the existing building envelope, instead. These new glass-clad circulation cores will complement a new communicating stair at the center of the complex that will be topped by a solar light monitor designed to bring light into the building’s center.

The removal of the mezzanines will lower the overall size of the project to 270,000 square feet and raise floor-to-floor heights to roughly 16 feet. The arrangement allows designers to add a raised floor plenum housing ducts, telecommunications, and electrical and plumbing infrastructure to each level. Also as a result, the old cell windows—a thin, horizontal band of glass set in from the exterior facade—now act as ribbon windows that will wash interior surfaces with reflected sunlight. Closer to the floor, a second continuous band of windows measuring 32 inches tall will wrap the perimeter of every level. Along the southern facade, this ribbon window is wrapped by a louver assembly made from aluminum plates. New planted terraces will rise through the structure’s perimeter.

Along the ground floor, new entry lobbies will embrace surrounding street life and create a “changing entry procession from the new entry on the street to the lobby and then security zone” for new users, Megan Duffy, senior interior designer at DLR Group, said. The complex will feature community rooms on these levels as well as a large planted plaza along the street.

Demolition phase for the project starts this fall; DLR Group expects to finish construction at the end of 2019.

Frank Lloyd Wright School of Architecture gifted a new Wright-designed home in Phoenix

The David and Gladys Wright House in Phoenix, Arizona, designed by Frank Lloyd Wright (whose 150th would-be birthday was last week), has been donated to the Frank Lloyd Wright School of Architecture. The house led a charmed life up until recently. Designed in 1952 by Wright for his son David, the 2,500-square-foot, mostly concrete house had come into the ownership of developers who wanted to bulldoze it and replace it with more profitable housing. News of this intention saw preservationists spring into action, but the standard procedures were scuppered as in Arizona, where private property laws hold strong, landmarking only saves a building for three years. On October 12, 2012, Michael Kimmelman of the New York Times explained the other, costlier method of saving the house: "The other prong of attack is to find some preservation-minded angel with deep pockets who will buy it from the developer. Preferably today." Cue Zach Rawlings. A custom homebuilding entrepreneur, Rawlings fell in love with architecture after exploring it across the country with his mother. As a young boy, he even caught a glimpse of the David and Gladys Wright house when he peered over the wall. Little did he know he would later save it. During his research, Rawlings came across architects John Lautner and Wallace Cunningham, both graduates of the Frank Lloyd Wright School of Architecture at Taliesin, in Wisconsin. Cunningham went on to work with Rawlings. "The first chance I got to call and hire architects while building homes, I called Wallace Cunningham," the developer said. Then one evening over dinner, Cunningham informed Rawlings about an Act of Demolition permit that had been filed for the David and Gladys Wright home. "I finished the dinner, got on the phone with my mom and told her I was flying to Phoenix in the morning,” said Rawlings, reacting to the news. "I asked her to please call the broker of the home and schedule a tour as soon as possible." Twenty-four hours after Cunningham and Rawlings had sat down, Frank Lloyd Wright's work had been saved from the wrecking ball. After that dramatic episode, Rawlings went on to meet Aaron Betsky, dean of the Frank Lloyd Wright School of Architecture at Taliesin in 2015. Over more food (this time lunch), Rawlings became inspired by Betsky's ambitions for the school, and the pair discussed the possibility of faculty members living there. Now the house will be donated to a fund under the Arizona Community Foundation for the sole benefit of the School.

"It’s transformative for the school and a fantastic opportunity," Betsky told The Architect's Newspaper. "One of the things that sets our school apart is living and working in Frank Lloyd Wright's built works—this addition only enhances that experience and lets us build on Wright’s legacy."

Betsky also acknowledged that "without doubt," some work has to be done on the house before educational programming can start there. A structural analysis has been carried out, though repairs to cantilevers and fixing leaks and touching up areas of corrosion also need to take place. Phoenix-based architect Victor Sidy is working on the building, as is landscape architect Chris Winters.

Arizonan architect Eddie Jones, principal at Jones Studio, will be teaching at the design studio specifically launched for the David and Gladys House. The studio will begin this fall and students will engage in the building and its six-acre site's renovation. (Originally, when Rawlings first purchased the house, it only came with a two-and-a-half–acre lot. Rawlings then bought adjacent lots to try and restore its original acreage.)

"This is all about the house becoming a place that can help students understand the relationship between the landscape and the built environment," remarked Betsky. He estimated that renovation work could take two-three years but admitted this was "optimistic." "We do not want to interrupt the [design] work going on inside," he said. Once restored there will be limited tours, and the house will be open to the public.

New models emerge in multifamily NZE buildings in Arizona

For years, builders across the western and southwestern regions have been moving in piecemeal efforts toward developing Net-Zero Energy (NZE) housing models for mass production, as new regulations envision the near-future proliferation of NZE building types, and energy-conscious consumers begin to ask for these structures as well. NZE buildings—a widely and variously defined concept—generally produce as much energy as they consume over the course of a year. They aim to reduce overall energy consumption while also generating renewable energy on site.

Builders have discovered that the best way to standardize NZE building methods is to lower overall building energy consumption first, and only then tackle costly additions like green technology. That means increasing insulation values within building walls while also tightening the exterior envelope. It is also important to place mechanical equipment within conditioned spaces and to program interior spaces with an eye toward solar exposure. After energy-efficient appliances are specified and a building energy analysis is conducted, designers move to size energy systems appropriately for the remaining energy loads. This tactic generates tight, efficient buildings that require smaller and cheaper solar panel installations. Because many of the building-related approaches—like constructing walls out of larger two-by-six-foot studs to create a wider insulation cavity—are easy to do and do not require builders to learn new skills, these approaches have brought down the potential cost of NZE buildings substantially.

Using the above strategies, builders like Phoenix, Arizona–based MODUS Development are helping to bring NZE residential buildings into the mainstream even further by developing NZE buildings with contemporary massing and detailing at both single- and multifamily scales.

Ed Gorman, founder and president of MODUS, has been hard at work streamlining and modernizing existing NZE housing models in an effort to stay ahead of California’s plan to have all single and most multifamily residential construction be NZE-equivalent by 2020. When the change comes, MODUS will be ready. Gorman expects the housing market to move toward the wide adoption of NZE homes either way.

MODUS has completed work on several NZE developments across California and Arizona so far—most recently, a 41-unit development called Equinox in Scottsdale, Arizona. The project—the first NZE apartment complex in Arizona—is organized around a central courtyard, and the one- and two-story units feature deeply recessed balconies and loggia spaces. Gorman explained: “The balconies serve as a heat sink” to facilitate passive ventilation, and the structures “create shade directly from the architecture, the way a modernist building would, instead of as an applied afterthought.” The project came in at the same cost as a non-NZE construction and is fully occupied. The firm’s portfolio for the year includes three new NZE developments: two 20-townhome developments in Scottsdale and a 32-unit multifamily development in Tempe, Arizona.

For Gorman, the NZE strategy is a no-brainer. “Highly efficient buildings have higher tenant retention, often sell for as much if not more, and cost less to build than traditional buildings,” he said. “If you can make it work in the desert of Arizona, you can make it do anywhere.” The future of building in Arizona and California, it seems, is heading toward Net-Zero.

Urban farming in suburban Phoenix becomes the basis for an entire community hub

While urban farming has become a great catchphrase, it has yet to take hold in a significant way in most American cities and suburbs. However, an excellent model for its progression is DSGN AGNC’s Spaces Of Opportunity, an 18-acre site in South Phoenix, Arizona, that is much more than just a place for growing: It’s also a community hub, an art center, and a music venue.

“The idea is that farming here is an excuse to bring services to this area,” said DSGN AGNC principal and founder Quilian Riano. “A way to bring economic opportunity.”

The semi-suburban area is home primarily to low- and middle-income Latino and African American populations. It’s also the site of a food desert, meaning that fresh food is very difficult to find. “There are more liquor stores than grocery stores here,” noted Riano.

DSGN AGNC’s master plan for the project, undertaken with the Desert Botanical Garden and a consortium of local nonprofits, called Cultivate South Phoenix, lays out segmented plots for community gardens and incubator farms. Master farmers will teach apprentices agrarian skills, helping them progress so they can get their own plots to work. Spaces in between the plots will be lined by rows of flowering fruit trees. The spaces along the edges of these plots will take on myriad uses, including washing and cleaning stations housed in repurposed shipping containers; compost and animal areas; a 500-person, colorful corrugated-metal and solar-panel-topped stage; playgrounds; an outdoor gym; and walls for art.

Work on the project is already underway, and Riano said he hopes it will be fully up and running by this coming summer or fall. Its creation involves an iterative process that Riano calls “design, wait, build.” In other words, the firm comes up with a plan, but then the community inevitably changes it to better meet their needs, and then the designers scramble to catch up with an adjusted plan.

“The community already moved faster than my previous design,” said Riano, referring to his early efforts to start growing on the site. “I had to rethink completely. The design is constantly re-questioned, rethought, and reworked.”

He hopes the project—both its content and its development—will become a model for future urban farms and for urban development in general. Incorporating so many types of uses has helped not only with interest, but also with fundraising. Already money has come in from local philanthropists and education and arts foundations.

“It’s a design that is very flexible and very participatory,” said Riano. “We’re using every angle.” The team also plans to coordinate with local schools, churches, and businesses to maximize participation and support.

Like many of DSGN AGNC’s initiative across the country, the project is also filled with learning lessons, like how to farm, how to build, and how to bring residents, designers, nonprofits, and city officials together. The firm’s other highly collaborative projects include Under El-Space Pilot, a pop-up park under the Gowanus Expressway in Queens; INPLACE, a community plan designed to bring urban art and design projects to Youngstown, Ohio; and La Casita Verde, a flexible community garden built on the site of a derelict lot in Brooklyn.

“It’s not just about building, but about rethinking the design process,” said Riano, of his diverse body of work. “Everybody learns, including me.”

A self-shading protective skin for the desert

facadeplus_logo1
Brought to you with support from
The Sandra Day O'Connor Law School, at Arizona State University (ASU), is a new six-story, 260,000-square-foot state-of-the-art law school, designed by New York-based Ennead Architects in collaboration with Jones Studio. The architecture of the building is inspired by the school’s progressive legal scholarship and outreach to the community through services like a public interest law clinic and the nation’s first not-for-profit teaching law firm. Ennead Architects say the Phoenix-based school is designed to act as an institutional agent of change dedicated to educating students and citizens on the importance of the law in shaping civil society.

In response to this initiative, the building design encourages vibrant connections between ASU, the College of Law, and the local downtown Phoenix community. A north-south “slice” through the courtyard massing creates an inviting and active public space with a pedestrian pathway that brings individuals directly into the central core of the law school, exposing them to the main lobby and three double-height spaces located at the heart of the building. Here, an expansive bi-folding glass door at the front of the school's Great Hall blurs the line between indoor and outdoor space, providing flexibility while offering a unique civic space to the downtown Phoenix community. Brian Masuda, associate partner at Ennead Architects, said this massing strategy paired environmental responsiveness with the desire to expose the core functions of the building to the public. The courtyard allows views into the building while self-shading large glazed areas of the facade. Sustainability was a key design driver throughout the process. A "hard-shell," which the design team considered a "protective skin" that performs as a shading device, wraps all of the exterior surfaces of the building. Ennead collaborated with Buro Happold to develop an articulated facade of Arizona sandstone with aluminum and glass windows. Masuda said internal programming and solar orientation prompted undulation in the window openings of the facade: "The aesthetic was driven by the program and environmental analysis. We wanted to make the stone facade modulate and calibrate in a way that when the windows got wider, fin elements got deeper." The facade is unitized and factory assembled, both to assure quality and to achieve a higher standard of thermal performance. The decision to work with a unitized system also helped with an aggressive one-year design and documentation schedule, said Masuda: "A unitized prefab facade system came into play because of the efficiency of the construction." Heavily insulated walls and roof also contribute to the efficiency of the shell. Mechanically, the building incorporates energy-efficient technologies, including chilled beams and under-floor displacement cooling. The project team said that because of the integration of these passive systems, they relied more heavily on the performance of the building envelope. "Hot spots" discovered through energy modeling were managed by the fine tuning of glazing types, the specification of high solar heat gain coefficients, and fritting in specific areas of the facade. The building is expected to reduce energy consumption by 37% compared to a baseline building, per ASHRAE 90.1-2007. Desert-adaptive planting and water features activate the landscape, helping to minimize on-site irrigation demands. The building taps into a campus-wide system of tracking energy usage, which is publicly accessible online through ASU’s “campus metabolism” website.

AIA award-winning cancer center showcases a minimalist brise-soleil

facadeplus_logo1
Brought to you with support from

ZGF Architects teamed up with Hensel Phelps Construction to deliver a custom 220,000-square-foot design-build cancer center for the University of Arizona at Dignity Health St. Joseph’s Hospital and Medical Center. The facility incorporates an “evidence-based, multidisciplinary model of healthcare” and utilizes the most modern technologies. An exterior shade system, along with chilled beams—the first to be used in an Arizona healthcare setting—greatly contribute to the facility’s sustainability. The east and west facades are clad with a solar shading system composed of repetitive rectangular quarter-inch aluminum composite panels (ACP) perforated with half-inch diameter holes yielding a 40 percent openness factor. The panels are folded once at a calculated angle, bending outward to reveal a shaded view of the surrounding desert context from the interior. This copper-toned assembly takes on the coloration of the landscape, adding a contextual aesthetic to the project. The assembly sits 30 inches off a facade of stucco and curtainwall glazing—a dimension that allows maintenance access to the exterior envelope for clean­ing and repairs. The panels are supported directly by a tube steel frame hung from a series of outriggers that cantilever from a hefty 16-inch reinforced concrete roof slab. These “diving boards” establish a dimensional grid that is constructed from the individual 15-foot-6-inch by 5-foot-3-inch panels. Additional outriggers on the same grid provide lateral support, tracking through the facade onto the slab edge.

The project delivery was design-build, per University of Arizona’s requirements. Mitra Memari, principal at ZGF, said the process benefitted from a close working relationship between ZGF and Hensel Phelps, which previously teamed up to complete a different project on University of Arizona’s main campus: “Having gone through this process, one of the key factors in making a design-build project successful is the relationship. Hansel Phelps knows ZGF very well and our design aesthetic, and we know Hansel Phelps very well…specifically individuals who worked on the project. This played well for the university and the end product." Memari said the success of the collaboration is evident in the fact that, for the $74-million project, over 90 percent of the 450 RFIs received were “confirming RFIs” to provide clear communications and exact resolution records. The primary purpose of the screen system is to reduce peak mechanical loads in the building. More than 10 variations of the assembly were studied by the architects, who were looking for a configuration that maximizes view and reduces glare, while properly shading the building. The project team was able to work with the fabricator from a very early point in the project, which allowed it to quickly optimize panel material, size, and configuration. A full size mock-up of a corner condition further helped to inform detailing decisions. Two types of shading panels—one per orientation— were developed in response to solar angles. The repetitive geometry also contributed to a quick construction schedule. The north and south facades feature a curtainwall system from KT Fabrication with three types of custom louver designs integrated in it. The most impressive is a series of canted glass fins incorporating a custom gray 60 percent frit patterning. The glass louvers denote the central area and the main lobby of the cancer center, providing a low-glare interior environment. Chilled beams play a major role in the energy efficiency of the building, reducing energy usage by 23 percent. The system was a first for healthcare projects in both the state and the university. Chilled beams utilize piped water located in the ceiling to naturally (and quietly) heat and cool the air using convection. ZGF incorporates chilled beams into nearly every project it takes on, and has introduced the system into many projects around the country. Beyond the facade, Memari said that one of the greatest successes of the project is an interior “communicating stair” that promotes walkability for staff and visitors through a carefully detailed, highly visible positioning within the building. The stair reads as a folded sculptural element to connect the facility’s tall 16- to 18-foot floor plates. The project opened in August 2015 and recently received a 2016 AIA Healthcare Design Award.
