Here are the 2020 U.S. WoodWorks Wood Design Awards winners

Jury’s Choice

This year's jury consisted of:

Danny Adams, Principal, LS3P Associates Marsha Maytum, Principal, Leddy Maytum Stacy Architects Eric McDonnell, Principal, Holmes Structures Matt Shaw, Contributing Editor, The Architect’s Newspaper

Project: First Tech Federal Credit Union Location: Hillsboro, Oregon Architect: Hacker Structural Engineer: Kramer Gehlen & Associates Contractor: Swinerton Builders First Tech Federal Credit Union’s motto is People First—and its new Oregon campus is designed to support and promote the health, comfort, and happiness of employees. Open offices are designed with an emphasis on equal access to natural light and views, and work stations are arranged to ensure that all employees can benefit from biophilic opportunities. Much of the building’s design draws on the beauty of the wood structural system, which is visible throughout the building. Glulam columns and beams frame floor-to-ceiling views to the park and the creek that surrounds the site on three sides. Raised floors conceal HVAC, electrical, and low-voltage systems, contributing to clear, uncluttered spaces that showcase the simple beauty of the cross-laminated timber ceilings. On the ground floor, a central commons with stadium-style seating ascends into a double-height atrium capable of accommodating large gatherings and presentations. LEED Gold-certified, the building achieved an exemplary score in the regional materials category as all of the columns, beams, and CLT panels were sourced and refined within 500 miles of the site. 156,000 square feet / Type III-A construction

Multi-Family Wood Design

Project: Adohi Hall Location: Fayetteville, Arkansas Architect: Leers Weinzapfel Associates; modus studio (AOR); Mackey Mitchell Architects Structural Engineer: Equilibrium ConsultingEngineering Consultants, Inc. Contractor: Nabholz Construction Adohi Hall at the University of Arkansas is the nation’s first large-scale mass timber student housing facility. A bold demonstration of sustainability, the 708-bed complex includes three main volumes, linked together to create a serpentine form set into a sloped site. Buildings A and B include five stories of mass timber—a cross-laminated timber floor and ceiling system supported by glulam columns and beams—over a concrete podium and partial basement. Building C is a one-story volume linking the two residential buildings. Maintaining acoustical separation was a significant issue. To expose the CLT ceilings, acoustical treatment was concentrated on top of the panels. To minimize the depth of the panel topping, and thus the floor-to-floor height, the team used an ultra-thin sound attenuation mat topped with less than 2 inches of heavyweight gypcrete and luxury vinyl tile planks—which surpassed the required STC rating of 50 between sleeping quarters. The use of wood both structurally and aesthetically makes this project a groundbreaking example of student housing design. 202,000 square feet / Type III-B construction

Commercial Mid-Rise

Project: 111 East Grand Location: Des Moines, Iowa Architect: Neumann Monson Architects Structural Engineer: Raker Rhodes Engineering, StructureCraft Contractor: Ryan Companies Anchoring a high-visibility site in Des Moines’ historic East Village, 111 East Grand includes three stories of offices above retail and restaurant spaces on the ground floor. It is the first multi-story office building to include floor and roof decks made from dowel-laminated timber. The DLT panels are supported by glulam post-and-beam framing, and the building is buttressed by a concrete core on the south face for lateral stability. Leveraging a unique benefit of mass timber, much of the structure is left exposed on the interior. This minimizes the need for tenant improvement while providing visual, tactile, and olfactive stimulation to the building’s occupants. Operable windows allow natural ventilation, and balconies on the west provide downtown views. The project is innovative in both design and delivery. From the outset, the core design team of architect and structural engineer collaborated closely with the mass timber engineers and general contractor. This enabled 111 East Grand to push boundaries and convey the accessibility of mass timber building design through its ultimate success. 66,000 square feet / Type III-B construction

Commercial Low-Rise

Project: Redfox Commons Location: Portland, Oregon Architect: LEVER Architecture Structural Engineer: KPFF Consulting Engineers Contractor: R&H Construction This adaptive reuse project transforms a pair of World War II-era warehouses into a light-filled campus for creative office tenants. Recognizing the historic and environmental significance of the existing wood structures, the renovation preserves and restores the original lumber. The trusses were sandblasted and remain exposed, highlighting the wood’s natural beauty. New 80-foot-wide clerestory windows were added to each roof to bring light into the large open floor plates, which are distinguished by column-free spans of 100 feet. To uphold the project’s heritage, both buildings were rebuilt using an industrial vernacular of ribbon windows and weathering steel cladding. During demolition, wood from an overbuilt mezzanine was salvaged to create a new timber and glass entrance structure that connects the two buildings. Over 6,500 linear feet of 4-by-12-inch boards were reclaimed, varying in length from 12 to 24 feet. The boards were fastened around new glulam members using large wood screws to create distinctive columns and beams. This innovative use of wood creates a welcoming entry that is expressive of both the project’s heritage and environmentally-conscious design. 60,000 square feet / Type III-B construction

Wood in Government Buildings

Project: Long Beach Civic Center⁠—Billie Jean King Main Library Location: Long Beach, California Architect: SOM ǀ Skidmore, Owings & Merrill Structural Engineer: SOM ǀ Skidmore, Owings & Merrill Contractor: Clark Construction Installer: WS Klem Located adjacent to historic Lincoln Park, the Billie Jean King Main Library provides a welcoming and flexible environment, with interior space organized into discrete and identifiable areas that maximize the use of square footage while enhancing accessibility. Built over an existing parking structure, the hybrid building includes an exposed glulam roof system over steel framing. It offers a variety of spaces, including group study rooms, independent study areas, a technology-driven makerspace, community center, and large central atrium that provides abundant natural light. Targeting LEED certification, the building also features rooftop photovoltaic cells, daylighting strategies, controlled air ventilation systems, and extensive glazing with architectural overhangs for solar protection.  The library is part of the Long Beach Civic Center Master Plan, designed by SOM to revitalize 22 acres of downtown Long Beach by creating a vibrant, mixed-use district. 96,000 square feet / Type IV construction

Wood in Schools

Project: Arts and Technology Academy Location: Eugene, Oregon Architect: Opsis Architecture; Rowell Brokaw Architects (AOR) Structural Engineer: catena consulting engineers Contractor: Hyland Construction As a teaching tool for middle school students to explore and learn about the interaction between the natural and built world, the Arts and Technology Academy’s honest and tectonic expression of structure, exposed building systems, natural materials, and daylighting create a physical environment conducive to a STE(A)M-centric curriculum. An iconic, umbrella-like folding roof comprised of steel frames, glulam beams, and wood decking—all left exposed—stretches across the length of the building above continuous clerestory windows. Appearing to float, it cantilevers in various locations, offering protection from the elements while creating a warm and inviting interior environment. Various sloped roof profiles pay homage to the surrounding residential vernacular while visually bridging the scale of the project’s two-story massing and surrounding one-story homes. An expansive photovoltaic array adorns the south-facing roof. Ample exterior glazing maximizes daylight and views during the day while serving as a warmly-lit community beacon at night. 95,718 square feet / Type IIIB construction

Institutional

Project: Oregon Conservation Center Location: Portland, Oregon Architect: LEVER Architecture Structural Engineer: KPFF Consulting Engineers Contractor: Lease Crutcher Lewis A blend of mass timber and light wood-frame construction, this renovation and expansion of The Nature Conservancy’s Oregon headquarters transforms a dated office building into a collaborative hub that reflects the environmental mission of its owner. Central to the upgrade is the addition of a 2,000-square-foot ground-level pavilion that serves as a gathering space for public events and collaborations. The building achieved LEED Gold certification, with features that include domestically-fabricated and FSC-certified cross-laminated timber panels, rooftop photovoltaics that produce 25 percent of the building’s electrical supply, efficient building systems and fixtures that reduce electricity consumption by 54 percent and water consumption by 44 percent, and a landscaping and subsurface filtration system to manage stormwater. Abundant daylighting, operable windows, and the use of local materials enhance comfort and connect occupants to the neighborhood and greater region. 15,000 square feet / Type VB construction

Green Building with Wood

Project: Oregon Zoo Education Center Location: Portland, Oregon Architect: Opsis Architecture; Jones and Jones (zoo design; insect zoo architect) Structural Engineer: catena consulting engineers Contractor: Fortis Construction Guided by the Zoo’s central theme, Small Things Matter, the design of this LEED Platinum-certified Education Center brings together a number of architectural and exhibition elements to create teachable, sustainable moments. Built with a combination of heavy timber, light wood framing, and steel, the two single-story buildings are inspired by the circular, woven nature of a bird’s nest; the resulting architecture creates an intertwined relationship between indoor and outdoor spaces that blends into the zoo’s landscape and exhibits. The sweeping cantilevered glulam entry roof and cedar-clad exterior draw visitors into the lobby’s interactive displays, insect exhibit, and event space. Sustainable design strategies include an expansive rooftop photovoltaic array, rain gardens with 90 species of native plants that provide wildlife habitat while cleaning stormwater for reuse, bird-friendly lighting, and fritted glass windows. The Center is expected to achieve net-zero energy certification. 20,000 square feet / Type V-B construction

Beauty of Wood

Project: Trailhead Building at Theodore Wirth Park Location: Minneapolis, ‎Minnesota Architect: HGA Structural Engineer: HGA Contractor: Kalcon A gateway to the Nordic ski and mountain bike trails of the Minneapolis Parks System, the trailhead building is used extensively by the public and area high schools for training and competitive meets. The highlight is an innovative mass timber roof that cantilevers in two orthogonal directions, tapers to a point at its tip, and is fully exposed on the interior. Glulam girders cantilever from 10 to 25 feet, following the trapezoidal shape of the roof, and are supported in part by a colonnade of Douglas-fir glulam columns and wood-frame walls. The unique roof and colonnade provide an elegant entry, while exposed wood on the interior creates a natural connection between gathering spaces and the outdoors. While embracing its surroundings with the use of mass timber, this building has also been embraced by its community. It was chosen as a hosting facility for the 2020 Cross Country Ski World Cup. 14,200 square feet / Type V-A construction

Adaptable and Durable Wood Structures

Project: Julia Morgan Hall Location: Berkeley, California Architect: Siegel & Strain Architects Structural Engineer: Bluestone Engineering Contractor: James R. Griffin Built in 1911, this Senior Women’s Hall at UC Berkeley is an elegant redwood bungalow with exposed wall and roof framing and a natural-finish interior. The building served as a gathering place for female students until 1969, when it was converted into a childcare center. First relocated in 1946, it was moved again in 2014—to the UC Berkeley Botanical Garden. To extricate the structure from its site and negotiate a winding road with overhanging trees, the building was divided into four segments, which were reassembled at the Garden, rehabilitated, and upgraded to meet current accessibility standards. All of the work—including cutting, installation, subsequent removal of temporary shoring and protection, and reassembly—had to be carefully executed to avoid damage. The exposed interior wood components required only minimal staining to conceal wear and tear, while the rich wood floors were refinished. The redwood siding was replaced as required and painted, and the team added a new wood porch. 2,255 square feet / Type V-B construction

Regional Excellence Awards

Project: 901 East Sixth Location: Austin, Texas Architect: TB/DS (Thoughtbarn/Delineate Studio) Structural Engineer: Leap!Structures Contractor: DCA Construction A design goal for this five-story office building was to make it seem at home in the creative, light industrial neighborhood of East Side Austin.  The structure is a hybrid of exposed cross-laminated timber floor and ceiling systems, and exposed steel—and is the first of its kind in Texas. It is clad in Corten steel, which forms a stable, rust-like appearance over time. A double-height lobby with a 25-foot bi-fold door allows the space to be opened to the street during special events; it also serves as a showcase for the exposed wood ceiling and full-height feature wall made from CLT off-cuts. 901 East Sixth achieved LEED Gold certification and was fully leased before construction was complete—at rates significantly exceeding the original pro forma. The project has been a celebrated financial success for its developers while receiving an enthusiastic reception from the public. 128,000 square feet / Type III-A construction Project: CoǀLab Location: Falls Church, Virginia Architect: William McDonough + Partners MEP Engineer: Staengl Engineering Contractor: HITT Contracting This unique project is intended to serve as a nucleus for research and testing of emerging technologies, products, and practices that will transform the construction industry. HITT Contracting envisioned Co|Lab as a showcase for building innovation that would utilize as many healthy materials as possible and exhibit smart emerging design and construction technologies. The mass timber structure—which includes cross-laminated timber walls and ceilings supported by glulam columns and beams—was chosen for its aesthetic, multi-sensory characteristics, light carbon footprint, and speed of construction. The design is based on cradle-to-cradle principles; instead of minimizing the building’s negative environmental footprint, the team wanted a beneficial footprint. Co|Lab is LEED Platinum-certified, and HITT is pursuing both Net Zero Energy and Petal certification. It was the first CLT structure in Virginia and the first commercial mass timber building in metropolitan DC. 8,650 square feet / Type V-B construction Project: The Continuum Location: Lake City, South Carolina Architect: McMillan Pazdan Smith Architecture Structural Engineer: Britt Peters & Associates Contractor: Thompson Turner Construction The Continuum is an innovative campus serving college, continuing education, and high school students in northeast South Carolina. After exploring options, the design team chose to renovate an existing big-box retail shell adjacent to downtown Lake City—but they added a unique structural solution. The roof of the central corridor was replaced with a large mass timber structure. Comprised of glulam columns and beams and nail-laminated timber decking, the addition allows daylight to penetrate to the center of the former retail floor. From the site plan and exterior façade to the interior finishes, the design is inspired by the imagery of the region’s deconstructed barns. As visitors approach the plaza, the view down the road reaches a reflection pool that runs under an extended overhang of the soaring NLT deck and into a green space intended for art installations. By strategically dividing and removing some of the existing structure with the glulam clerestory, the design creates circulation spaces flooded with light that invite students to gather. Linked by these open spaces, the building incorporates multiple educational functions into one cohesive floor plan. 46,592 square feet / Type IV construction Project: MFAH Sarah Campbell Blaffer Foundation Center for Conservation Location: Houston, Texas Architect: LakeǀFlato Architects; Kendall/Heaton Architects (AOR) Structural Engineer: Cardno Haynes Whaley Contractor: WS Bellows Wood Structure & Engineering Consultant: StructureCraft Builders Art conservation facilities tend to be thought of as sterile laboratory spaces, but that isn’t true of this one. From the outset, the design team wanted to incorporate natural biophilic materials, specifically wood, to provide an appropriate warmth and texture to the laboratory environment. This hybrid project includes glulam columns and beams and dowel-laminated timber roof panels, as well as steel structural elements. The DLT roof is left exposed, offering a welcome contrast to the wall finishes that are necessarily neutral. The overall result blends the science and art of conservation to create spaces that perform superbly to their technical requirements while offering a warm and welcoming work environment for the art conservators. 30,000 square feet / Type IV construction Project: DPR Office Location: Sacramento, California Architect: SmithGroup Structural Engineer: Buehler Engineering Contractor: DPR Construction When DPR Construction decided to relocate its office to downtown Sacramento, it was seeking to connect with the community it serves on a deeper level. In choosing mass timber, it also saw an opportunity to give employees the benefits of a biophilic design and enhance their workday experience. The project, which involved adding a second story to a 1940s-era concrete and masonry building, includes cross-laminated timber roof and wall panels, and glulam columns and beams. Among its unique features, the building includes CLT shear walls, a first in California. It also exceeds regulatory requirements, targeting net-positive energy—which reduces its carbon footprint from the standpoint of operations and maintenance. The use of mass timber augments this goal by reducing embodied carbon and acting as a carbon sink. This is DPR’s sixth net-zero energy office, and the firm is seeking LEED Platinum, Petal, and WELL Building certifications. 34,508 square feet / Type V-B construction Project: Pike Place Marketfront Location: Seattle, Washington Architect: The Miller Hull Partnership Structural Engineer: Magnusson Klemencic Associates Contractor: Sellen Construction Pike Place MarketFront adds 50 vendor stalls; 40 low-income and senior apartments; commercial, retail and office space; a public roof terrace and walkways; and 300 underground parking spaces to the Pike Place Market Historic District in Seattle. Comprised primarily of heavy timber, light wood framing, and cast-in-place concrete, the project draws contextual inspiration from the simple utilitarian character of the existing market. This historic precedent, combined with timber’s carbon-negative footprint, abundant local sourcing, and speed of erection, made it an easy choice for the project team. While timber is typically used to support gravity loads, the structural engineer designed composite timber and steel framing members to manage portions of the building’s lateral loads. Enclosed by a timber-frame glazing system, the monumental structure includes a vibrant hall housing retail and restaurant spaces while preserving historic views of Puget Sound. Heavy timber columns, beams, and decking serve as both structure and finish, bringing the natural beauty of wood to the space. 210,000 square feet / Type IV construction Project: Rhode Island School of Design – North Hall Location:  Providence, Rhode Island Architect: NADAAA Structural Engineer: Odeh Engineers Contractor: Shawmut Design and Construction For this six-story residence hall at RISD, the design team chose a hybrid system of cross-laminated timber floor and ceiling panels supported by steel framing to achieve goals that included beautiful design, environmental sustainability, and an aggressive construction schedule. Exposed CLT ceilings add beauty while echoing themes of sustainability that students experience as part of the school’s curriculum. In addition to reducing the project’s carbon footprint through the use of CLT, the new hall is expected to use a quarter less energy and less than half the water of a typical residential structure of similar size. The system also provided a schedule advantage. Working closely with the fabricator, the team optimized the layout of panels to minimize erection time. Five-ply panels were manufactured in 8-by-50-foot spans—allowing a single panel to span the building’s width. The erector exceeded expectations by completing the superstructure in less than three weeks. By prioritizing innovation and working to achieve a shared vision, the RISD project team successfully brought the first hybrid CLT-steel residence hall in New England to life. 40,790 square feet / Type III-B construction Project: Sideyard Location: Portland, Oregon Architect: Skylab Structural Engineer: catena consulting engineers Contractor: Andersen Construction Photos: Stephen Miller When the City of Portland built a new one-way couplet connecting to the Burnside Bridge, it created a leftover berm space that is now home to Sideyard. Shaped like a wedge, this five-story project prioritizes access to public transportation, bicycle access, and pedestrian openness. It includes retail and restaurant space at street level, additional retail on the second floor, and office space above. The structure includes a cross-laminated timber floor and roof system supported by a glulam post-and-beam frame, with concrete lateral cores. Sideyard is part of the new Central  Eastside community envisioned in the Burnside Bridgehead Framework Plan, designed to strengthen the connectivity of the area with the Westside downtown core. Its use of locally-sourced materials showcases Oregon wood species in a truly unique fashion. 23,202 square feet / Type III-A construction Project: Tre Søstre Location: Grand Marais, MMinnesota Architect: Salmela Architect Structural Engineer: Meyer Borgman Johnson Contractor: Taiga Design + Build Tre Søstre is located in a former fishing village, close to the shore of Lake Superior. Two decades ago, the owners purchased the abandoned property, converted three severely damaged buildings into rental units, and built a heavy timber “boathouse” as their own live/work space. They recently added three units—designed to make a bold statement while remaining sensitive to the scale and materials of the neighborhood. Despite modest footprints, the structures include multiple cantilevered volumes and decks, a strategy inspired by Scandinavian farm buildings. Each unit has a covered entry deck located above grade. Interior stairs lead down to ground-level and up to second-floor bedrooms. The top floors cantilever to the east, creating an open living space with unobstructed views while providing cover for the patios and decks off the bedrooms below. Spatial adjacencies were carefully considered to provide areas of protected privacy and open gathering within a relatively dense cluster of units. 3,440 square feet / Type V-B construction

2019 Best of Design Awards winners for Infrastructure

2019 Best of Design Award for Infrastructure: North Chiller Plant, University of Massachusetts Amherst Designer: Leers Weinzapfel Associates Location: Amherst, Massachusetts

The new North Chiller Plant replaces a smaller plant and enhances the University of Massachusetts Amherst campus’s master plan by locating the new plant outside a major view corridor. The parallelogram footprint maximizes usage of the narrow site by reconceiving the typical rectangular orientation of the chillers into an “angled parking” layout. The exterior continues this geometry with an angled interface between the insulated metal panels punctuated with channel glass above and a glazed base. The base is highest on the northern side to allow vehicle access and lowest on the southern to reduce solar gain. The transparent ground floor promotes “technology on display” by exhibiting the color-coded piping and equipment, transforming the building into an engaging element of visual learning for the campus.

America's largest mass timber building opens at the University of Arkansas

America’s largest mass timber building has opened at the University of Arkansas. Spread across a series of interconnected structures, Adohi Hall is a 202,027-square-foot residential project constructed from cross-laminated timber. Boston-based Leers Weinzapfel Associates led a national design team of heavy hitters for the $79 million project: local practice modus studio, the St. Louis-based Mackey Mitchell Architects, and Philadelphia's OLIN helped bring the sustainable, 708-bed student complex to life. Located on a sloping, four-acre site on the Fayetteville campus’s hilly southern end, Adohi Hall features a nature-centric design with room for classrooms, a community kitchen, lounges, a rooftop terrace, and more.  Linked by a ground-level passage called the “cabin,” the large-scale, dual-volume complex snakes around the linear lot and is configured around three courtyards. As the nation’s first CLT "living learning" setting, Adohi Hall was built for undergraduates but is also targeted for architecture, design, and art students, and features ample programming to reflect that. Throughout the four-story facility, communal areas encourage collaboration while “workshops,” or maker spaces, provide students with the opportunity to rehearse or host performances, record music, or participate in other live/learn events. The design team integrated exposed structural wood throughout the project to remind residents and visitors of the building’s groundbreaking construction. Exposed timber columns, ceilings, and trusses bring a sense of warmth to the interior spaces, while generous light also shines in through the floor-to-ceiling glass windows in the cabin area and provides views of the surrounding landscape designed by OLIN. The majority of Adohi Hall’s facade, which lightly cantilevers over the first-floor, is less obviously about wood and features zinc-toned paneling with copper and white accents. In a statement, Andrea P. Leers, principal of Leers Weinzapfel, noted the stark contrast between Adohi Hall and the other Collegiate Gothic-style architecture on the university’s campus. She noted that the contemporary residential building is fitting for the site despite its differences, especially given the administration’s commitment to sustainable design. “We drew inspiration from the regional context of the Ozarks, creating a living/learning environment powerful enough to be a destination remote from the center of campus,” said Leers, “and the wood-based construction system we developed forges a bond between setting, human comfort, and sustainability.”  Adohi Hall (adohi meaning woods in Cherokee) was named as a tribute to the tribe members who passed by the site on the Trail of Tears. The area’s long history as a heavily forested region motivated the architects and the university to pursue this ambitious mass timber project. Leers Weinapfel Associates told Architectural Record that they responsibly-sourced European spruce, pine, and fir for the structural components of Adohi Hall, while cypress was selected to outfit the interior.  It makes sense that the University of Arkansas—with its Fay Jones School of Architecture committed to researching and teaching wood-based construction—would be the first school in the country to build a large, CLT-based residential complex. As mass timber manufacturing grows in Arkansas and the surrounding states, it’s a possibility that other Southern institutions will follow Adohi Hall’s lead.

Facades+ Boston will dive into the trends reshaping the city

facadeplus_logo1
Brought to you with support from
On June 25, Facades+ is returning to Boston for the fourth year in a row. The conference, organized by The Architect's Newspaper, is a full-day event split between a morning symposium and an afternoon of workshops led by top AEC practitioners. Leers Weinzapfel Associates (LWA), a Boston-based firm with projects nationwide, is co-chairing the conference. Panels for the conference will focus on the changes underway in Boston, ranging from new educational structures, the city's new tallest residential building, and historic preservation projects. Participants for the conference's symposium and workshops include Behnisch Architekten, Knippers Helbig Advanced Engineering, Pei Cobb Freed & Partners, Bruner / Cott, Arrowstreet, Consigli Construction, Walter P. Moore, Autodesk, Atelier Ten, Harvard GSD, the Wyss Institute, and Okalux. In this interview with The Architect's Newspaper, LWA's designer and business development representative Zhanina Boyadzhieva and associate Kevin Bell, the conference co-chairs, discuss their firm's growing body of work and the developmental trends within the city of Boston. The Architect's Newspaper: Boston is known as a relatively quiet city with a predominantly low-slung skyline. How is current development reshaping that identity and what does it mean for the future? Zhanina Boyadzhieva: Boston is indeed a “quiet” city, but it is also a hub of innovation and creative thinking. In the past few years, we have observed dynamic design work, largely by local firms, on several fronts: 1) creative re-envisioning of historical landmarks through readaptations and additions such as Smith Center at Harvard University and Congress Square in downtown Boston 2) careful insertions of new landmarks in the skyline such as One Dalton 3) fast development and growth of existing or new resilient neighborhoods such as Harvard’s Allston campus. Each design solution addresses unique urban conditions and entails holistic thinking about city planning, resilience, and sustainability, coupled with a sense of function, form, materiality, and human experience. Naturally, facades combine all of these considerations and become dominant players in the reshaping of cities. The diversity of approaches we observe—controlled material juxtapositions of old and new, sculptural form-making, and playful screening strategies—are testaments to ongoing design experimentations here. There is a search for new methods to address creative reuse, high performance, material fabrication, and user experience.  AN: The city possesses one of America's largest concentrations of brutalist buildings, as well as large historic districts. How can Boston embrace its heritage while moving forward? Kevin Bell: The rich building history of Boston, including modern landmarks like City Hall, and its brutalist companions make for wonderful urban fabric for intervention and a great place for an architect to practice. This history should serve to elevate our expectations for new buildings and major renovations in the city. The recent warming to Boston’s brutalism, its strong geometry and bare materials, is welcome, encouraging designers to consider rather ignore these local icons. It presents the opportunity to consider adaptation and re-envisioning through sustainability’s lenses, the human experience, and materiality. If we can dramatically improve the energy efficiency and human use in these sensitive historic buildings, we can achieve the same in new construction and create a model for continued improvement. AN: What innovative enclosure practices is LWA currently executing? KB: As a firm, we have a legacy of designing efficiently in an urban context. Often, our site is an existing historic building or a tightly constrained sliver of land, or sometimes, there's no site at all. This fosters a sensibility within the studio toward compact volumes, materially efficient, with taut fitted skins, a practice that serves us well as we work to make evermore energy efficient and sustainable buildings. We're also redefining our performance expectations around our clients' commitments to energy efficiency, many of whom have established operational carbon neutrality as their aim by mid-century. The enclosures we design today will be part of that efficiency equation. They must be considered to be part of a carbon neutral organizational environment as a performance baseline above simple compliance with today's codes or target certifications. Envelope performance, especially the use of innovative glazing materials, is a logical extension of the way we think about reactive, efficient space and energy efficiency targets in building enclosure design. Our Dartmouth Dana Hall renovation and addition, under construction now, is an example of this process and practice. We worked closely with the college to define a program for building reuse around its energy use reduction targets that dramatically improved envelope efficiency. Through the design process, we worked with our design and construction partners to continually refine the design while holding to incremental improvement in energy efficiency at each step; our modeled efficiency improved even as we moved through cost reduction exercises. The result is a highly insulated building, triple glazed throughout, with a thermally improved, south-facing glass curtainwall system combining vacuum insulated high-performance glass modules with integrally solar shaded, triple glazed vision glass as part of a building with a predicted energy use index (pEUI) in the middle twenties before the introduction of site renewables. AN: Which materials do you believe are reshaping facade practices? ZB: Materials are the agents of larger design strategies shaping the practice such as resilience, sustainability, and human experience. The aim to rethink and cherish historical buildings, for example, leads to a careful layering of existing and new materials that contrast and simultaneously enhance each other. Heavy textured concrete at the Smith Center is supplemented by light and open transparent glass, green walls and warm wood. Traditional brick block at Congress Square is juxtaposed with a floating glass box on top of sculptural fiber-reinforced plastic panels. On the other hand, the vision to create new landmarks that celebrate and reshape the Boston skyline result in the careful sculpting of distinctive volumes as in One Dalton, a tall glass skyscraper with careful incisions of exterior carved spaces for human use. Finally, the goal to produce energy efficient but playful envelopes leads to a game of patterns composed of an inner insulated layer with an outer wrapper of perforated metal screens or angled aluminum fins. Each choice of material and its manipulation reflects a larger vision to create a unique experience in the city. Further information regarding Facades+ Boston can be found here.

MIT to consolidate its architecture school in a warehouse revamped by DS+R

MIT’s School of Architecture and Planning (SA+P) is currently scattered all over the school’s Cambridge, Massachusetts, campus, but not for much longer. The university announced on December 14 that it had tapped New York’s Diller Scofidio + Renfro (DS+R) to convert the historic Metropolitan Storage Warehouse into a central design hub. The idea of renovating the Metropolitan Warehouse, which was added to the National Registry of Historic Places in 1986, has been kicking around since June of this year. At the time, SA+P dean Hashim Sarkis expressed the desire to consolidate the physical design and research components of the school into one location. The proposed changes would preserve the warehouse’s distinctive red brick facade (likely because of its historical significance). DS+R will be partnering with Boston’s Leers Weinzapfel Associates, no strangers to academic work, to bring 200,000 square feet of classrooms, galleries, workshops, studio spaces, and an auditorium to the former warehouse. A makerspace, accessible to the entire campus, will also be installed under the administration of Project Manus, a group responsible for integrating and updating such spaces at the school. The selection of DS+R began with a long list of potential architects that was put forth by MIT’s Office of Campus Planning (OCP). Representatives from every department of SA+P, Project Manus, and OCP then whittled the list down to four finalists. The remaining studios were invited to give private presentations in October, and feedback on each was taken from SA+P students and faculty, as well as representatives from the city. “A project of this scale and complexity,” said Sarkis, “which demands a design sensibility informed by both art and technology—along with a deep understanding of architecture education as well as the role of public space—is made for a firm like DS+R.” No estimated completion date for the project has been given yet, nor has a budget estimate, though MIT says that the school is in productive talks with alumni about fundraising to pay for it.

Design collaboration brings mass timber residence halls to the University of Arkansas

A national design collaboration led by Boston-based Leers Weinzapfel Associates and including Arkansas-based Modus Studio, St. Louis–based Mackey Mitchell Architects, and Philadelphia-based OLIN has created America’s first large-scale, mass timber interactive learning project, already under construction at the University of Arkansas. Working off of a “cabin the woods” concept, 708-bed Stadium Drive Residence Halls feature fully exposed, locally harvested wood structural elements. The residence halls are a pair of snaking buildings joined in a central plaza, and include classrooms, dining facilities, maker-spaces, performance spaces, administrative offices, and faculty housing. The five-story buildings, totaling 202,027 square feet, are clad in a zinc-colored paneling, while copper-toned panels are scattered along each floor that appear to float above the heavily planted backdrop. Inside, wooden columns, beams and cross-bracing are all displayed to present a sense of warmth, and to connect students with Arkansas’s local ecology. The halls terminate with large study rooms at the end of each floor, which light up at night and act as beacons for the rest of the campus. The panels were constructed from Cross Laminated Timber (CLT), while the structural columns and beams are made of glulam, where layers of wood all facing the same direction are laminated together under pressure. Each arched building curves around a courtyard or common park area and students enter the complex through a covered “front porch” at the northern building’s main entrance. The central gathering room that connects the hall’s two wings has been dubbed the “cabin,” and despite being relatively small, packs in a hearth, community kitchen, lounge spaces, and a planted green roof. Each hall also features a double-height ground floor lobby with floor-to-ceiling windows that allow uninterrupted views of the surrounding landscape. “The interwoven building and landscaped courtyards, terraces, and lawns; the beauty of timber structure and spaces; and the excitement of performing arts and workshop facilities will make this newest campus residential community a destination and a magnet,” said Andrea P. Leers, principal of Leers Weinzapfel Associates. Leers Weinzapfel is no stranger to working with timber, as its multidisciplinary design building for UMass Amherst wrapped up construction late last year. The project is expected to finish in 2019, and will anchor a new master plan for the University of Arkansas campus.

UMass Amherst completes cross-laminated timber Design Building for architecture, other programs

Boston-based Leers Weinzapfel Associates recently completed construction of the new Design Building at the University of Massachusetts Amherst, the first academic building in the U.S. to use a Cross Laminated Timber (CLT) as its primary structure. (See images of the building under construction here.) Targeted for LEED Gold, the building includes other sustainable architectural features like bio-swales for water runoff filtration, a green-roof which doubles as an outdoor classroom, and the largest installation of wood concrete composites in North America. The building is described by Principal Architect Andrea Leers as “a teaching tool for the design disciplines.” Leers made the case that educational environments, especially those for design school, can serve a pedagogical function in the training of young architects. Leer stated further that:
From my own teaching experience there’s nothing more potent than being able to talk with students about the space around you—in this case, the building’s collaborative configuration, innovative structure, considered material and detailing choices, environmentally-driven site, and synergistic landscape concepts that define the project.
The building is organized around an interior atrium lit during the day by several skylights. This daylighting strategy reduces energy consumption and provides the school with a bright central space for exhibitions, design critiques, lectures, informal gatherings, and other events. The studios and classrooms are arranged around the atrium, visually connected to the commons through window apertures that allow visitors to glimpse the work being done by the students and faculty. The design of the building’s commons also emphasizes the unification of the university’s departments of Architecture, Landscape Architecture and Regional Planning, and the Building and Construction Technology program into one singular facility. In addition to its extensive use of wood products, the architects chose to clad the building with copper-finished aluminum panels that protect the highly-efficient envelope. Though the building fills much of the site, the landscape design by Stephen Stimpson Associates strategically uses native plants and local paving materials to connect the building to the larger campus. In the end, the building cost $52 million to construct, a price tag that was partially funded by Massachusetts State Legislature, and adds 87,500-square-feet of additional interior space to the university. Suffolk was the construction manager.

Leers Weinzapfel Associates designs timber multidisciplinary design building for UMass Amherst

The University of Massachusetts (UMass) Amherst, about 100 miles west of Boston, will get a new multidisciplinary addition this fall. Boston-based Leers Weinzapfel Associates designed the UMass Design Building, set to open November 2016 in time for winter classes. It will unite the architecture, landscape architecture, regional planning, and building technology departments into one facility. The building is currently under construction. See our slideshow above and images below for exclusive construction photos (we've included a few renderings, too). When the project opens, it will be one of the largest mass timber structures in the United States. The building's interior will feature Cross Laminated Timber (CLT), an engineered wood known for its durability and lightness. Projects can use CLT to replace materials with higher embodied energy such as steel, concrete, and masonry. While it has been popular in Europe and Canada for some time, CLT is gaining traction in the United States, mostly on the west coast (one notable project is the Bullitt Center in Seattle). The 87,000 square foot Design Building will also rely on a glue-laminated wood frame, a wood composite floor, and a copper anodized aluminum building envelope. The facility will bring together over 500 students and 50 faculty across the four departments into a space that is transparent, open, and light-filled. The design features a lowered atrium with a zipper truss, an upper courtyard, and offices and classrooms rising in a coil, explained Andrea Leers, principal and co-founder of Leers Weinzapfel Associates. A major goal of the design was to help facilitate greater interaction between student and faculty. The firm put studios and offices on each floor, said Tom Chung, principal at Leers Weinzapfel. Yet there is also an element of independence, as studios on each level are at one end, while offices are at the other. The studios will be medium-sized, able to fit up to 5 sections. “UMass did not want a lecture hall,” Leers said. Instead, the ground floor—which has no predefined programming—includes stairs that double as seating for presentations and a flat floor for absorbing activities and other events. Also planned is a cafe, exhibit space, and libraries. The Design Building site is a sloped area on the southern part of the UMass campus between Stockbridge Way and Kevin Roche’s 1975 Haigis Mall. “It is a challenging site,” said Leers. The building will rise to four stories on one end and three stories on the uphill. The landscape design by Stephen Stimson Associates relies on a bioswale for water filtration. Leers Weinzapfel stressed the close connections between the exterior and interior, with the concept of building-as-landscape and landscape-as-building. In separate conversations with both Leers Weinzapfel architects and UMass building technology specialists, both emphasized the educational component of the Design Building—how the building itself would serve as a living instructional example. “We wanted this building from the early stages to be a teaching tool for advanced timber construction,” said Peggi Clouston, associate professor of building and construction technology at UMass Amherst. “The project uses CNC milled wood,” said Alex Schreyer, building construction and technology program director at UMass Amherst. “There are extremely tight tolerances. It’s innovative with these spans of 25, 26 feet.” But there are challenges to building in timber in the U.S. “The forests are in a state of decline. They are not properly managed, and weed species [smaller species] are choking out larger ones," said Clouston. These weed species are easy fuel for forest fires. The use of mass timber reflects the university’s roots in agriculture—the university was founded under the President Abraham Lincoln-signed 1862 Morrill Land-Grant Colleges Act. The university was first called the Massachusetts Agricultural College. “It was a public process,” said Josiah Stevenson, principal at Leers Weinzapfel of the design. The total cost of the project is $52 million, with $36 million going toward construction. When it came to obtaining funding, the UMass's efforts were partially an “activist intervention,” Leers explained. UMass faculty went to the state legislature for funding, and spoke with former Massachusetts Congressman John Olver. He was taken with timber, said Clouston. Currently down the hill from the Design Building site is Wood on the Plaza, a white ash timber bridge shell installation at the Fine Arts Center Plaza. The architecture department will be moving out of its home in a Brutalist Kevin Roche building. The university will reuse the current architecture and building technology spaces, while razing the landscape department building, originally built as a dorm. You can find more Design Building information, construction photos and time-lapse videos online. The construction manager for the project is Suffolk Construction.
