Snapping Facade explores a sustainable design strategy that utilizes elastic instability to create dynamic motion at the building envelope. The current dynamic shading systems adopt either glass enhancement or motorized mechanical movement. This study introduces snapping-induced motion as an alternative actuation mechanism to control apertures, and proposes Snapping Facade as a new dynamic shading system. Based on analytical and numerical study, the researchers fabricated the assembly of a prototype snapping facade and validated the hand-operated snapping motion. The proposed snapping facade suggests a novel way to recycle the strain energy stored in structures via elastic instability.

Albina Yard is the first building in the United States made from domestically fabricated cross-laminated timber (CLT). This new 16,000-square-foot speculative office building utilizes mass timber construction, with a glue-laminated timber frame and CLT panels manufactured and prefabricated in Riddle, Oregon. The project’s primary goal was to utilize domestic CLT in a market-rate office building that would pave the way for broader adoption of renewable mass timber construction technologies in Oregon and the United States. The design approach reflects a commitment to this sustainable technology by developing an architecture focused on economy and simplicity, material expression, and the careful resolution and integration of all building systems to foreground the beauty of the exposed Douglas fir structural frame.“As a structural strategy, mass timber is very similar to a cast-in-place concrete structure in terms of layout and function of its individual elements. The main difference is the character and humaneness of the remaining spaces. It is very well-suited for this type of use.” —Nathaniel Stanton, principal, Craft Engineer Studio (juror) General Contractor: Reworks Structural Engineer: KPFF Consulting Engineers CLT Supplier: DR Johnson Lumber CNC Routing: Cut My Timber Honorable Mention Project: Cummins Indy Distribution Headquarters Architect: Deborah Berke Partners Location: Indianapolis, Indiana This new office building reinforces an active pedestrian experience that is connected to downtown Indianapolis and its parkland. The unusually slender floorplan and high ceilings provide abundant natural daylight for every space and minimize reliance on electricity. A high-performance “calibrated” facade and an integrated system of fins and shades limit heat gain and increase thermal comfort. Honorable Mention Project: Zurich North America Headquarters Architect: Goettsch Partners Location: Schaumburg, Illinois Located on a 40-acre expressway site in suburban Chicago, the North American headquarters of the Swiss Zurich Insurance Group reflects the company’s global reach and commitment to sustainability. Composed of three primary “bars” that are offset and stacked, the arrangement creates unique spaces for collaboration, opens views of the surrounding landscape, optimizes solar orientation for amenities, and provides programmatic flexibility.
“The towers are large enough to serve as a headquarters for a Fortune 100 company, such as Amazon, and would anchor the entire district both architecturally and financially. The towers and interlinking skybridge would be an iconic addition to Portland’s skyline and a destination for locals and tourists alike. The elevated garden would be a tropical respite from the gray of the city at any time of the year and provide breathtaking views of Mt. Hood and the entire city skyline.”For now, the WKA scheme remains just that—Prosper Portland began project solicitation earlier this month via an RFP, which is due January 19, 2018.
Portland International Airport (PDX), stretched to its limits and lacking enough space for security operations, is planning a massive $1.3 billion renovation as reported by The Oregonian.
The planned five-year project, if approved by the airlines that operate at the airport, will be the first major overhaul of the terminal since its construction in 1956. The realities of post-9/11 travel—TSA checks, body scanners, endless lines—have been difficult to incorporate into a terminal that was not designed for such needs.
Another issue that PDX—if not all airports—faces is as the tourism industry grows, capacity becomes a concern. Portland, in particular, has been seeing a record-setting amount of visitors over the past years, and the airport is struggling to keep up.
"We have made do with what we could until now," said Curtis Robinhold, executive director of the Port of Portland, to the Oregonian. "We're simply running out of capacity to manage the passenger flow we're getting today, and that we'll be getting in the days to come."
The redesign of the terminal will minimize the mixing of arriving and departing passengers to improve circulation, as well as create more open space in the pre-security area. The plan estimates that the airport’s upgrades will be able to accommodate 35 million travelers annually, which is almost double the number of travelers from last year.
Other improvements include implementing structural upgrades to make the building earthquake-resilient and replacing the roof and aging electrical and plumbing systems. A $265 million parking garage expansion is also expected to begin in 2018.
Port of Portland officials are working with the airline carriers, who will be the ones financing the project, to create an acceptable plan. It will be voted on in the fall, and if approved, construction is scheduled to begin in 2020 and completed in stages.
