Located within the former Holy Trinity German Church, an 1877 structure designed by Patrick Keely in Boston’s South End, Finegold Alexander Architects inserted an eight-story, extruded glass-and-steel condominium residence. The Lucas preserved solely the original stone walls, tower, and arched windows of the facade and “slid” in the new residences to maintain its iconic nature within the neighborhood. Ellen Anselone, a Principal at Finegold Alexander Architects, said in a press release “the design team sought to harmoniously marry the old and the new.”

Because “the existing walls couldn’t take the weight of a new building,” Anselone told AN, “the idea was to slip this new structure inside that existing one.” Finegold Alexander Architects had the facade 3D-scanned on the interior and exterior to assist with putting the drawings together. Working with the contractors, the project team evaluated the integrity of the exterior walls and the condition of the stonework. The original stonework was primarily intact and required minimal restoration. As seen in the pre-construction photos, the original stone walls were thick enough to stand alone during construction. Finegold Alexander’s design did require some cutting down of the original window sills on the first floor to create space for new windows. It also relocated the existing stair on the street to allow for accessible entry to the building. Many iterations of intervention were considered before arriving at the final design, which is mostly an extrusion of what is seen in the floor plan. The stone buttresses are continued up into the new steel structure. In the detailing of the new construction, there is a perimeter of steel framework, constructed right up to the interior of the existing stone walls, which then the vertical steel was anchored on. The floors were then installed and braced. Above the roofline of the original church, the new structure is clad in a simple metal panel rainscreen and curtain wall enclosure. The detailing was meant to be an extension of the historic language of the facade and also create a contemporary interpretation, in opposition to mimicry. The system follows the vertical lines established in the original facade, in both the metal panel and curtain wall. There are vertical fins which jut out over an exterior balcony, reminiscent of the original buttresses but clad in the same metal panel as the rainscreen system and tied back to the new steel structure. Being an adaptive reuse project, immense coordination was required between the architect and the contractors. One of the biggest challenges was efficiently locating the waterproofing where the new construction meets the existing wall. The process was hands-on, and Finegold Alexander Architects were onsite to work out those details with the contractor. Once the windows and curtain wall were installed, everything was diligently water-tested to ensure the tightness of the building envelope.

Bohlin Cywinski Jackson’s water-inspired facade

The School of Freshwater Sciences is the first of its kind in the country, supporting a regional initiative to establish Milwaukee as a global hub for water-related research and technology. Located in the city's Harbor District, the project is an anchor for the re-utilization of industrial brownfield sites. Designed by Bohlin Cywinski Jackson and Milwaukee-based architecture firm Continuum, the project is a long, linear addition to an existing building that was once used as a ceramics factory. The facility accommodates a dock for research vessels that have direct access to Lake Michigan. Natalie Gentile, ‎associate principal at Bohlin Cywinski Jackson, said the design concept was about discovering a facade solution inspired by the visual qualities of water. She said flying into Milwaukee over Lake Michigan gives a unique vantage point of the water, and provided a departure point for the school's facade concept: “We loved the way the water responds to different daylight conditions, and we were hoping to capture some of that in the building elevation." The building integrates custom TAKTL panels with a Kawneer curtain wall into a thoughtful composition of horizontal and vertical regulating lines. The majority of the exterior shell is flat, but the project team was able to produce depth and curvilinearity through subtle two-dimensionally profiled shapes. Curves were rarely—but impactfully—incorporated into the facade. Custom-profiled louvers cast undulating shadow lines over the building, while a parapet wall camouflages the reading of the facade as a flat surface.

The primary section of the facade is flanked by a set of gently curved bays and an elliptical stairwell inspired by boat hull geometry. The curtain wall incorporates extended mullion cap extrusions of varying length, evoking verticality of dripping rain, and cantilevered panels that give the facade a sense of movement akin to the flow of water. The curtain wall system picks up the geometry established by ribbon windows on the central portion of the facade. The compositional logic of the resulting grid is a response to a state of Wisconsin requirement that limits view glass percentage on facades dependent on solar orientation—in this case, the south-facing building was allowed to be composed of 30 percent openings along its primary facade. A set of ribbon windows set to this target established a grid with spandrel glass and rainscreen panels infilling opaque areas. The project team conducted numerous color studies looking at how to add dimension to the flat facade. The team arrived at a solution that incorporated five colors into a specific patterning that utilizes a proportioning system of one-thirds of a standard panel size to limit material waste. Gentile said the panels played a significant role in producing the water-inspired visual effects she sought: "I'm really pleased with how the TAKTL panels are performing in terms of meeting our architectural goals for replicating the way water reflects light under different lighting conditions.” She said photography taken in the morning versus the evening shows how the building—clad in blue panels—can range anywhere from golden to violet hues. “We were very concerned about the sheen of the panels. We knew this modest sheen was important to getting us that changing coloration and reflectivity." Bob Barr, principal of Continuum, said the project successfully worked with the state's regulations on view glass percentage to producing an impactful facade: “To have something very visible after the limitation of the glazing is why we played so much with the patterning of the spandrel glass."

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.

VernerJohnson Sets Museum Ablaze with Dichroic Glass

Faceted facade evokes regenerative prairie burns.

For most projects, admits VernerJohnson's Jonathan Kharfen, architects steer clear of evoking a potentially destructive force like fire. But Museum at Prairiefire, the American Museum of Natural History (AMNH) outpost in Overland Park, Kansas, proved an exception to the rule. Because Prairiefire houses AMNH's traveling exhibits, its content is constantly changing, and thus provided little guidance in terms of an overarching design concept. Kharfen instead looked to the location. "What is the area about?" he asked. "For me the first thing that came to mind were the prairie burns. Coming from Boston, I'd never seen anything like it." Using dynamic materials including dichroic glass and iridescent stainless steel, VernorJohnson crafted a faceted high performance envelope that embodies the color, movement, and regenerative power of fire. Not long after landing on the fire metaphor, said Kharfen, "I knew of a couple of materials that would be perfect, because for me it's all about movement and light." He began researching dichroic glass, a composite glass that changes colors depending on the angle of view. The museum's sustainability goals—the project is targeting LEED Silver—dictated that the material would double as an insulating unit, the first such application in the United States. But that presented an additional challenge, as products with the dichroic properties embedded in the glass itself would break the budget. To lower costs, the architects collaborated with fabricator Goldray Industries to design an assembly incorporating dichroic film from 3M. The solution turned out to be an aesthetic boon as well as a cost-cutter, as the film itself carries a flame-like pattern. "It's subtly dimply, it's animated, it's beautiful," said Kharfen.

Kharfen's team paired the dichroic glass with a second shape-shifting material, Light Interference Coated (LIC) stainless steel, ultimately applying panels in a variety of color and finish combinations. "With the stainless steel, I wanted to create [the appearance of] flame bursts and sparks," explained Kharfen. "I didn't want to apply it in a random way." Instead, the architects arranged the panels in a gradient, with blue (near the bottom) giving way to burgundies and reds and finally to golden yellow. For Kharfen, it was not enough that the materials themselves convey a sense of life and movement. "I wanted them to be dynamic shapes, dynamic in plan as well as in elevation," he said. His solution—a faceted curtain wall—upped the project's technical ante. To avoid cluttering up the lobby space with columns, Kharfen worked with structural engineers Structural Engineering Associates to design a custom support system of stainless steel tubes fronted by angled mullions, to which the curtain wall is attached as a veneer. To accommodate the 14 unique angles involved in the faceting, curtain wall manufacturer Kawneer developed a new adjustable mullion, a hinged plate with a 180-degree range of movement. Given the museum's ever-changing content, the architects treated the exhibit spaces as "black boxes," said Kharfen. "For the solid areas I wanted to evoke the overlapping, curved forms of the hills." The client, Fred Merrill of Merrill Companies, loved the stonework at VernorJohnson's Flint Hills Discovery Center in Manhattan, Kansas, which suggests striated rock formations. "He asked, 'Can't we just do that here?'" recalled Kharfen. "I said, 'No, we're going to do something different.' I wanted a gradient." To cut costs and simplify installation, the architects whittled a more complex scheme down to a mix of two different stones in each band, with the bands varying in width. Again, the referent is fire: the walls begin with a charcoal-colored architectural cast stone before moving through Kansas limestone in shades of red, brown, gold, and off-white. Together, the stone-clad exhibit halls and the lobby curtain wall complete the picture of a prairie burn. "I wanted the fire elements to engulf and connect the solid volumes," said Kharfen. "I did them as lines of fire, because, historically, that's how these fires were set." But while the burn metaphor extends to every level of detail, including the flicker-flame-inspired sloping at the tops of the doors and windows, for the project architect the museum design ends where it began: with the primary materials. Speaking again of the dichroic glass, he concluded, "I cannot think of a material that looks more like fire than this glass."
