Regardless of materiality, we have had great success—and fun—in our exploration of computational design and digital fabrication methodologies. For the ongoing LA Rams stadium, we worked with Zahner to develop the metal cladding system. Our team was able to optimize the structural performance and detailing of the perforated metal skin by leveraging parametric design tools and fabrication technologies. In the end, the design of a custom perforation pattern was able to be realized by a digital workflow that exported analytical models directly into fabrication files for over 150,000 panels.AN: Minneapolis is experiencing a period of tremendous growth. A factor in this growth is the concentration of manufacturing and facade management firms. In your opinion, how does this proximity between design practices and manufacturers influence the execution of projects in the area? JS: We are somewhat spoiled by access to world-class glazing, sheet metal, and curtain wall fabricators right in our backyard. In many ways, one of the biggest benefits is easily facilitated collaboration between makers and designers, especially at those early "what if" design stages when fabricator expertise can help give an innovative concept legs. I think one of the biggest areas for untapped collaborative potential is the very unique brain trust that exists in the local region in terms of custom curtain wall engineering. I'm especially looking forward to this panel to see representatives from some of these influential players together in the same room to discuss the current climate and what the future holds for Minneapolis and beyond. WB: The most dynamic and successful designs attain prominence only by close cooperation and understanding between the design, manufacturing, fabrication, and installation teams. This is true in facade design perhaps more so than in any other subset of the building industry. With the importance of the building enclosure being far from lost on a design community in such a climate, combined with the fact that Minneapolis is a national hub for the production of cutting-edge systems; this design and construction community is exceptionally well-positioned to capitalize on this collaborative potential. As the desires and needs for high performance, increased quality, and more formally demanding skins continue to evolve; it’s exciting to see what creativity and innovation, whether in the form of panelization, various fabrication technologies, or other, will permeate into local works and how. AN: Increasing regulation coupled with the growing demand for sustainable design is fueling the proliferation of high-performance enclosure systems. How are Alliiance and StudioNYL addressing this challenge and what lessons can be learned from Minneapolis? JS: To start with, we're trying to set our goals on every project well beyond the minimal baseline of code regulation and treat performance and sustainability as integral components to the design process. Our office is a signatory to the 2030 Commitment which means we're also doing as much measuring as we can so that we can build a living data set to analyze and track trends as we go. The surge in the accessibility of analytical tools is having an impact across the profession, and we're incorporating these tools more frequently and earlier in the process to predict performance and even feedback into the process as a design-driver. Being located in Minneapolis, our frame of reference, of course, is cold climates and all the challenges they bring—so that means we often come to a project with a critical eye towards envelope performance. Marrying these technical demands of thermal performance, durability, and occupant comfort with early design concepts can make for a very rich approach to facade design—an approach that can be a valuable reference outside the region as all buildings become more closely scrutinized for performance. WB: As a firm, we’ve been pursuing sustainable initiatives in our enclosure, as well as in our structural, projects for years. Fortunately, this has become a prevailing sentiment found in not only my ASHRAE committee work where widespread thermal bridging code provisions are near, but also on the job site where the application of thermal break technologies is no longer viewed as a “specialty item."
As a result, “high performance” is being pushed even higher. Our work with Payette on Amherst College’s new Science Center, a 2019 COTE Top Ten award winner, is one shining example of this; while the recladding of the Social Security Administration’s half-century-old HQ we have underway with Snow Kreilich and HGA in Maryland is another.
One of the most compelling byproducts of such works is how quickly these tenets are reaching the mainstream, where I’ve even witnessed firsthand how net-zero and developer-driven goals can align on a mixed-use project. Another collaboration with Pyatt Studio on South Dakota’s Pine Ridge Reservation is seeing 21 net zero, low-income homes being built.More information regarding Facades+ Minneapolis can be found here.
