It is always interesting when the architect attempts to explain away results by alluding to the client not allowing him to do something, therefore something not so good was done. A knowledgeable client is always a great aid to a project, and unenlightened clients can thwart good ideas, and unambitious clients can have different agendas, but no architect is forced to do something bad. At worst, certain good ideas are not implemented, and when that happens the project design must be rethought so that the result is at least coherent. There is a disturbing tendency these days (shades of Edward Durell Stone) to hide issues of irresolution in buildings by the application of a screen. In this case, it [Aspen Art Museum] fails at hiding the sins and robs the passerby of a sense of scale and what could be a richness of detail. As a result it reminds one of a wicker basket dropped over the top of something else. Moreover, the idea of wood being the only material which can relate to mountains boggles the minds of many, the great Swiss architects not the least of them. The design of the roof space frame is interesting but there seems absent from the result any rational justification for clear span. Museums are marvelous opportunities: a synthesis of light, systems, movement, and modulation of space. Paradise Lost, once more. Harry Wolf Harry Wolf Architect

If you haven’t seen or read the entirety of The Shining then you're going to want to fix that right away—like, right now. Use the time you would have spent reading this 225-word story with, say, watching the two-and-a-half hour film. It's great; you'll love it. Okay, with that disclaimer out of the way, let’s continue. You'll want to continue. The Stanley Hotel in Estes Park, Colorado—the inspiration for Stephen King’s Overlook Hotel—has launched a public design competition to create a 10,100-square-foot permanent hedge maze like the one that Jack chases Danny through at the end of the film. Designs for “The Stanley Maze” must be submitted by the end of this month and include 1,600 to 2,000 Alpine Currant hedge bushes. A ribbon cutting for the new maze will be on April 30th at the hotel’s third annual film festival. “There are few hotels in the world that share a history and story as unique as that of the Stanley Hotel,” said John W. Cullen, owner of the property, in a statement. “I am thrilled to share this special moment in my life and the hotel’s history. We have built this place together over the years and I'm excited to invite everyone to be a part of its legacy through this special design contest.” With one maze under his belt, we think Bjarke Ingels is an obvious front-runner in the competition.

The Vancouver-based New Buildings Institute (NBI) tracks energy efficient built work, and their 2014 update, “Getting to Zero”, provides a snapshot of the emerging U.S. market for net-zero buildings—those are structures that use no more energy than they can gather on site. In the United States, California leads in the number of low and zero energy projects with 58, followed by Oregon (18), Colorado (17), Washington (16), Virginia (12), Massachusetts (11), Florida (10), Pennsylvania (10), Illinois (8), North Carolina (8), and New York (8). NBI also compiled a database of all their buildings. They say architects and developers interested in pursuing net-zero design could find inspiration there, searching according to their local climate and/or building characteristics. The database includes energy-efficient and high-performance buildings that are not net-zero, as well. Though the trend has succeeded in garnering attention and excitement among many designers, true net-zero buildings remain elusive in the built environment. So far NBI has only certified 37 buildings as net-zero. That ranking is based on performance—each building underwent a review of at least 12 months of measured energy use data. If piece-meal projects aren't yet adding up to a groundswell of net-zero design, NBI is also pushing systemic change—rigorous energy efficiency standards recently adopted in Illinois took cues from the group's Core Performance Guide.
Plate tectonics, honeycombs inspire new Denver Botanic Gardens research center.For their new Science Pyramid, the Denver Botanic Gardens sought a design that delivered more than just aesthetic impact. "They wanted an icon, but they also wanted to show an icon can be high performance," said Chris O'Hara, founding principal of Studio NYL. Studio NYL and its SKINS Group worked with architect Burkett Design and longtime Botanic Gardens general contractor GH Phipps to craft a structure to house the institution's conservation and research efforts. "People think of the Botanic Gardens as a beautiful place to go, but what most of them don't realize is what happens behind the scenes," said O'Hara. "The whole concept was to showcase that, and to educate the public not just about what the Botanic Gardens are doing, but a little more about their environment." Clad in a Swisspearl rain screen that serves as both roof and wall, the Science Pyramid's biomimetic design reconsiders the relationship between the built and natural worlds. Tasked with building a pyramidal structure with dynamic glass elements, the Burkett Design team turned to two natural metaphors. The first was the tectonic shifts that created Colorado's mountains, the second, the defensive structures built by honeybees. The geological metaphor influenced the building's form, a twisting, reaching variation on a pyramid designed to take full advantage of its site. The biological metaphor informed the building's skin, dominated by cement composite panels cut into honeycomb-like hexagons. Though they originally imagined a heavily glazed facade, Studio NYL soon realized that transparency would be impractical, given the projection elements involved in the Science Pyramid's exhibits. They opted instead for a rain screen system comprising custom-cut Swisspearl panels. The rain screen reduces thermal gain by venting hot air before it reaches the building. It encases the roof as well as the facade's vertical elements, the second such use of Swisspearl panels worldwide, and the first in the United States. "Here you don't hear about rain screen roofs often," said O'Hara. "Using the technology as a roof system was a little different." Because they still wanted some glass, Studio NYL incorporated electrochromic glazing from View. "They can tune the building—the user has a flip switch to black it out," explained O'Hara. "At the same time, you can have a visual connection to the gardens." To further boost performance, Studio NYL worked with Cosella-Dörkin to layer a UV resistant weather barrier system under the open joint rain screen. "Whereas the form was about this iconic, biomimetic structure, on a technical level, everything was about performance," said O'Hara. Fabrication and installation were complicated by two factors: a compressed timeline, and a need to work around the Botanic Gardens' ongoing operations. To help with the former, the Burkett Design team leaned heavily on digital fabrication, including having the structural steel digitally cut. As for the latter, the construction crew was forced to develop creative solutions to spatial restrictions. "There were a lot of logistical problems given that we were in the center of an active botanic garden," said O'Hara, noting that only machinery below a certain size could be brought to the site. "The primary axis we had could only go up twelve feet, to the extent that we were pushing tree branches out of the way with a broom." The design-build team came through in the end. "It's really quite spectacular," said O'Hara. But while the Science Pyramid achieves the landmark status the Botanic Gardens had hoped for, it nonetheless defers to its context—the gardens themselves. "The building is very oriented to the paths you take," said O'Hara. "Everything has a different moment. If you enter one way, you see the glass spine; if you come another, you see the canopy. It's playing constantly against the juxtaposed landscape."
On Saturday, August 2, I had the opportunity to attend the ribbon cutting ceremony and member's opening of the new Aspen Art Museum (AAM), designed by this year's Pritzker Prize winner, Shigeru Ban. The event took place at the tail end of AAM's annual ArtCrush festival, which gathers artists, art collectors, curators, gallery owners, celebrities, and philanthropists from around the world to celebrate contemporary art and raise money for the museum through an auction. While the museum opening was well timed to take advantage of the glut of luminaries in town for ArtCrush, it did catch the building itself—Shigeru Ban's first permanent museum project in the U.S.—at an awkward moment in terms of its construction. Workers were still finishing up the last details—including installing a piece by Jim Hodges called With Liberty and Justice For All (A Work In Progress) that will occupy the sidewalk—but it was intact enough to get a good impression of what visitors will experience when it opens to the general public on August 9. To kick things off with a bang, AAM commissioned New York–based artist Cai Guo-Qiang to put together a day-time firework display known as Black Lighting, which was spectacular, though a little frightening in its resemblance to artillery fire. While you can wait for my critique of the museum (coming soon) for a full run-down of the design, the basic concept was to integrate the building respectfully within the built fabric of Aspen while at the same time taking full advantage of the natural beauty of its Rocky Mountain setting and providing ideal spaces for displaying an ever changing array of art. AAM is not a collecting institution. Its director, Heidi Zuckerman Jacobson, is always on the search for the next upcoming artist, and thus the gallery spaces had to offer a lot of flexibility. Shigeru Ban stacked three floors of galleries against the party wall (one below grade, two above), wrapped them in circulation and offices (at the back), enclosed it all in a white metal and glass curtain wall, and then wrapped the street faces (it's a corner lot) with a woven Prodeema screen whose wood veneer offers a warm, hand-crafted expression that cozies up to Aspen's masonry and timber context. (Front Inc. provided facade consulting services. The architect of record is Cottle Carr Yaw of Basalt, Colorado.) The screen is not uniform. Its apertures are larger toward the corner and top of the building, providing the best views there, while concealing the emergency stair and back of house spaces at the opposite ends. A glass elevator at the corner allows visitors to look out at the surroundings as they ascend or descend. A grand stair between the screen and glass curtain wall provides access directly to the top of the building, where there is a cafe and terrace/sculpture garden. (For the opening the terrace was occupied by another Cai Guo-Qiang installation called Moving Ghost Town, which involved a sort of barnyard pen where two African Sulcata tortoises with iPads mounted to their shells were free to wander, or hide their heads in the dirt, as one found it fit to do throughout the reception. The iPads played video that the tortoises had "filmed" while wandering through a nearby Colorado ghost town.) The rooftop/top floor spaces can be open to one another or closed off, depending on the weather, by way of a manually operated sliding glass wall. Another stair just inside the curtain wall, which mirrors the one outside, provides direct access to the gallery spaces. The idea behind this circulation scheme is that, like on Aspen's ski slopes, visitors can climb to the top before "sliding" down through the exhibition spaces. Structurally, the building is made up of a composite system that includes post-tensioned cast-in-pace concrete (which offered the most efficient floor-to-floor dimensions (about 16 feet), allowing the architects to provide 14-foot-high ceilings (to the bottom of the beam) in the gallery spaces while fitting the building within Aspen's 47-foot height limit), exposed structural steel pipes, and an exposed timber space frame for the roof. The timber space frame is, in my mind, the highlight of the architecture. Fabricated by Spearhead Timberworks in British Columbia, it features three types of wood: spruce chords, birch web members, and Douglas fir end caps. The webs have curving profiles that create flat interfaces with the top and bottom chords of the truss. This allowed the connection between web and chord to be made with a single steel screw—as opposed to a gusset plate connection—driven in from above so that it is invisible from below, giving the impression that it is an all-wood structure. Ventilation ducts, sprinklers, and lighting integrate well within the space frame structure as well. Four out of the six galleries feature some access to daylight, while two are completely artificially lit. (L'Observatoire International designed the lighting scheme.) This was one aspect where the collaboration between Shigeru Ban and Heidi Zuckerman Jacobson shows. Heidi originally wanted black box spaces where she could have total control over the lighting, in keeping with at least the past 50 years of curatorial thinking and gallery design in this country. Shigeru, however, convinced her (after a tour of naturally lit gallery spaces) that she could have the control she wanted while taking advantage of the dynamic qualities natural light. After all, art is created in natural light. Another place the collaboration shows is in the openness of the building (see the roof) and the variety of ways in which one can traverse it. Shigeru reportedly at first wanted a very controlled circulation sequence, providing one way to proceed through the museum, but Heidi put her foot down, explaining that in the U.S.A., especially in the West, people expect a little more freedom of movement.
Denver’s Union Station, a multi-modal transit hub built by architecture firm Skidmore, Owings & Merrill, opened up last month. The ribbon cutting ceremony severed the notion that transportation hubs are drab, gray places that smell suspiciously of food products and cleaning chemicals. What does the Union Station Bus Concourse do differently? Everything, apparently. Its sweeping design acts as a converging point for local commuters, airport bound travelers, and out-of-city destinations. Spanning the Amtrak train tracks is an outdoor canopy built from white arch trusses. The half-moon structures swoop up to 77 feet in height before touching back down 120 feet away on the opposite side. The majestic arches offer shade and weather protection to the platforms below. The interior’s design brings in terrazzo floors, yellow glass tile work, skylights, and glass pavilions. Beyond the terminal's attention to design, the station marks a critical economic and environmental breakthrough for transit systems. "This project represents a major investment in transit-oriented development with extraordinarily far-reaching social and economic consequences," said SOM design partner Roger Duffy. "The bus concourse is the result of nearly a decade of thoughtful public consultation and bold design. Its completion helps realize this community's aspirations for a truly transformational neighborhood and landmark public project." Union Station has the capacity for 200,000 daily trips—a number that officials expect to hit by 2030. Designers hope it sets a precedent not just for transportation abilities, but acts as a beacon for other public transit structures nationwide.
With only one month remaining before Facades+ PERFORMANCE opens in Chicago, our exciting lineup of the industry’s leading innovators is gearing up for an electrifying array of symposia, panels, and workshops. Be there for this groundbreaking, two-day convergence of design and construction professionals, presented by AN and Enclos, coming to Chicago, October 24-25th. Join Chris O’Hara, founding Principal of Boulder-based Studio NYL, for his day-one symposium, “Ludicrous Speed: the Design and Delivery of Non-traditional Facades on a Fast Track,” and learn first-hand from the experts the technologies and fabrication techniques that are revolutionizing the next generation of high performance facades. Register today to redefine performance for 21st century architecture, only at Facades+ PERFORMANCE. After graduating with a B.S. in civil engineering from the University of Notre Dame, Chris O’Hara began his career in New York with M.G. McLaren Consulting Engineers, where he was confronted with a host of unique structural engineering projects, from amusement park rides to New York’s Rose Center for Earth and Space at the American Museum of Natural History with Ennead Architects. Things really got going for O’Hara when he joined up with London-based Dewhurst Macfarlane Partners and began to work closely with visionary architect Rafael Viñoly. Leading high-profile projects like Viñoly’s David L. Lawrence Convention Center in Pittsburg and the Watson Institute for International Studies at Brown University in Providence, Rhode Island, O’Hara developed innovative structural solutions that allowed for the pioneering architect to exercise the breadth of his architectural expression. In 2004 O’Hara relocated to Boulder, Colorado to launch his structural engineering firm, Studio NYL, who have since become renowned for their diligent application of emerging technologies and inventive structural solutions. Their adventurous, detail-oriented work has drawn the attention progressive architects, both local and global, while O’Hara’s integration of multiple design software programs and use of complex geometries made him a literal poster-boy for Autodesk. In his daily practice, O’Hara oversees the use of BIM and other advanced analytic technologies and leads the design of innovative forms in BIM, REVIT, and direct-to-fabrication CAD/CAM softwares. Collaborating with fellow Facades+ presenters Rojkind Arquitectos, O’Hara has pushed the boundaries of structure and design on pioneering projects like the aluminum and glass enclosure of the Cineteca National and the digitally fabricated metal skin of Liverpool Flagship store in Mexico City. Designed and built in little over a year, the Liverpool Flagship store is a stunning product of international collaboration, technological instigation, and fast-paced delivery. Studio NYL lead the design for the structural elements of the atrium, rooftop park and pavilions, skylight, and stainless-steel facade for the 30,000 square meter shopping center. Using BIM software to coordinate the work of multiple trades on complex geometries, Studio NYL and Rojkind Arquitectos constructed the fluid folds and fine reliefs of the shopping center’s sound-blocking double-layer facade.

How do you solve the problem of wildlife crossing a major highway? Build a bridge! On Sunday, the NY Times reported that Michael Van Valkenburgh and Associates (MVVA) was named winner of an innovative competition to build a wildlife crossing over a Colorado highway. Together with construction company HNTB, the team's design calls for a lightweight precast span that will improve animal and driver safety as well as help reduce habitat fragmentation. Finalists for the ARC Competition were announced last year including proposals from Balmori Associates, Olin Studio, Janet Rosenberg & Associates, and Zwarts & Jansma Architects. (View a gallery of the finalists' proposals below.) The competition carried a $40,000 award. MVVA's proposal is called hypar-nature after its structural system comprised of hyperbolic paraboloid vaults that support a vegetated wildlife crossing wide enough to create areas of distinct habitat for a variety of animals including forests, shrubs, and meadows. An expansive fence along the highway would shepherd animals to the bridge. Designed to be a prototype for a network of future crossings, the design features modular precast pieces that can easily be set into place over the roadway. While Colorado has not dedicated funds to the project or determined what site to pursue, officials hope to study the finalists' proposals.
