Yes, We Need Daylight
A
t a recent trade show, I was having a conversation about indoor air quality, daylighting, and the other usual today’s-buildings-are-so-
much-better-places-to-work topics. As the conversation progressed we, of course, touched on the productivity aspect. It was mentioned that much of the research about daylight and air quality and the impact each has on productivity was getting rather long in the tooth. I agreed, but thought to myself that the research must still be valid because there hasn’t been any widespread call for new studies or questioning of the established work. A couple of weeks after that discussion I received a release from the people at View Inc., Milpitas, CA (viewglass.com), one of the manufacturers of dynamic glass. The information described some new research they had commissioned with Alan Hedge, professor in the Dept. of Design and Environmental Analysis at Cornell Univ., Ithaca, NY (cornell.edu).

tudent unions are not entirely new structures on university campuses, but their purpose and design have evolved with changing student demo-
graphics and educational goals. Student unions as a building type were f irst construct-
ed on university campuses during the late 1950s into the early 1970s. Before that, student social spaces might have been the lobby or hallways of administrative or academic buildings or, for larger gatherings, in auditoriums and recreation centers, according to Jay Smith, AIA, LEED AP, principal and design director, Duda|Paine, Durham, NC (dudapaine.com). Those original student-center buildings are now reaching the end of their life span, he observed. “These facilities are becoming functionally obsolete from the standpoint of servicing, infrastructure, technology, and building-envelop functionality. Historically, their internally focused planning and programming fails to address current student social, academic, and professional needs.” Expansions of many existing student unions have occurred from the 1970s into the early 2000s, often result-

community. The reconfigured building advances a new model for student centers through landmark form and an emphasis on shared and flexible spaces. The result is a welcoming, interactive, and interdisciplinary hub for the entire campus community, according to Duda|Paine Architects’ website (dudapaine.com). The architecture reinforces pedestrian circulation through strong visual links to surrounding buildings and to previously disconnected areas of campus. Each corner provides a prominent landmark, orienting students and visitors to interior spaces. The iconic Technology Tower—inspired by research at the university—marks the location of a future pedestrian bridge to North Campus. The reconfigured building is open and dynamic, redefining NC State’s campus identity and advancing a new model for student-life facilities with an emphasis on shared and flexible spaces. Key amenities include diversified dining, centralized student organizations, and integrated exterior/interior environments. Among other awards, the project received the 2016 Association of College Unions International (ACUI) Facility Design Award.
SUSTAINABILITY Talley has been designated as a Leadership in Energy and Environmental Design (LEED) certified building at the Silver level. Sustainable features of the building include:
• • • •
open design that maximizes daylight and occupant health and productivity building materials that were sourced regionally or of recycled content low-emitting finishes and furniture that preserve indoor air quality high-efficiency plumbing fixtures and a 50,000-gal. underground cistern that harvests rainwater for use in irrigation
•
landscaping with drought-tolerant plants native to the region, paved paths designed to reflect heat, and rain gardens that naturally filter and absorb stormwater
•
energy-saving, high-performance mechanical systems and windows, exterior shading, and roofing material that reflects the sun
•
infrastructure necessary for future installation of green roofs, which are covered by a layer of plants that reduce a building’s cooling costs and environmental impact from stormwater runoff
•
during construction nearly all discarded materials were reused or recycled, and robust recycling and composting programs now exist to ensure sustainability in the building’s daily operations
•
strategic proximity to public and campus transit, resulting in reduced automotive use from the building’s users.
Talley is the fourteenth university building since 2011 to earn LEED certification, bringing the total amount of LEED-certified space on campus to more than 900,000 sq. ft.
ing in conglomerate buildings that at one time accommodated incremental growth but are at odds with campus designs and the evolution of university-life programs. “Student unions now serve as a university’s crossroads to connect the entire campus and its community in a tangible and direct way,” Smith said. “These buildings reinforce and enhance existing campus connections, spirit, and character, but also become transformative for their institutions. Student unions should provide campus social hubs and be extroverted; they must create a dialogue between inside and outside spaces that facilitate large gatherings and events, present diverse dining opportunities, and welcome people inside by showcasing active program and lounge spaces. Students want a place to connect socially, but also provide resources for academic and career success. To achieve this, student unions now house a great variety of social spaces, from small-scale quiet nooks to large, f lexible meeting and conference rooms.” Today’s student unions serve future students and alumni in addition to current students. They are often the origin point for campus tours for prospective students, new student orientations, convocations, and alumni events. Benchmarking of comparable institutions provides insights into important programmatic components, contemporary building character, and architectural expression. Ultimately any renovation or new building serves the current student population, but also must facilitate competitive recruitment, support student retention, and ensure alumni support, Smith commented. According to Smith, the success of student unions relies on establishing connections to other campus academic, recreation, housing, and dining facilities. In addition, the variety and character of student amenities within the building have been evolving, and student expectations of available features and comforts have continued to escalate. “In recent years, students and universities have expressed a high level of expectation about student-center design, which is a wonderful thing for architects,” he said.

ballrooms and theaters that host campus and public events, multiple retail venues that generate revenue for the campus, diverse dining options, and traditional bookstore components.” Student unions are primarily for students, but a variety of other constituents have input, according to Smith, “Most student unions are funded from student fees, which are separate from academic funding sources. Students, student-organization representatives, student senators, administration from student affairs, cultural curators, and dining and bookstore constituents are the primary voices in determining a facility’s programmatic makeup. Students serve as ambassadors, who convey the spirit of the building’s program and design,” he said. Academics still play a role. “Many scholarly events are held in student centers,” Smith noted, “and students use these buildings as alternatives to the library for work and study. In fact, collaborative spaces within student-organization suites, flexible meeting rooms, and a mix of quiet lounge spaces are where academics intermix with the social aspects of student life. Other key program drivers include entertainment, relaxation, and socialization opportunities; the incorporation of technology; and openness and visual transparency to other internal spaces and the outdoors. These features come together to shape buildings that are inviting to students and mark the evolving functionality of the building type.

meeting and scheduling systems, digital resources and WiFi infrastructure, we see a more fundamental level of human interaction as equally essential. We’re designing buildings that perform, that meet their programmatic needs, but also provide a variety of spaces for critical interaction between individuals and larger groups.” TECHNOLOGY IS EVERYWHERE
Technology is ubiquitous on university campuses today, and student unions have been influenced on many fronts with regards to technology and social media. Social media is used to promote and advance student support on referendums that fund building projects, advertise significant events and gatherings, and celebrate milestones in the design and construction process. Surveys distributed through social media have influenced dining choices, student lounge and meeting room sizes, and retail options, Smith commented. “Technology has also significantly impacted transportation access,” he said. “It’s no longer necessary for students to stand for long times waiting for shuttles in a specific area. Instead, many campuses have incorporated tracking programs and apps available on screens in the building or on student’s phones, so students are notified when their transportation will arrive. Gaming is another area that is transforming the way traditional ‘game rooms’ operate and are positioned within buildings. Gaming is now incorporated into lounges that are front and center, so students can watch or participate in groups. To accommodate this, the edges of games rooms are more open and widely dispersed. The efficiency of meeting spaces has also been significantly impacted by technology that allows groups to reserve spaces and to collaborate and present material in new ways.” Technology is not just about social media and gaming, however. “Building functionality and sustainability have also been greatly influenced and made possible by new technologies. Systems track composting and recycling, building energy, and water usage and make this information more accessible. There is a greater expectation that student-union design incorporates green roofs and other sustainable elements. This expectancy is good for everyone,” Smith said. Features unheard of in student unions just a few years ago are being introduced. “We are also seeing spaces tradi12

Pippenger Hall, certified LEED Gold by the U.S. Green Building Council, Washington (usgbc.org), received accolades for its ceramic fritted façade from the A|N 2017 Best of Design Awards and has been honored by the American Institute of Architects’ Tampa Bay Chapter. The project was designed by ikon.5 architects/Harvard Jolly Architecture, a joint venture between Harvard Jolly Architecture, St. Petersburg (harvardjolly.com), and ikon.5 architects of Princeton, NJ (ikon5architects.com). Conceived as an athenaeum for business scholars, the three-story, 68,000-sq.-ft. building draws inspiration from its Tampa Bay setting and indigenous coral stone that lines the bay’s shores.

openings in coral stone, creating a porous vessel that allows sunlight and landscaping to penetrate deep within the structure’s core. Additionally, the pocked surface of these ancient stones inspired a rich, spatial interrelationship of rooms that promote collaborative learning and serendipity. Like coral stone, portions of the building are removed to reveal voids filled with light and life. The building’s surface, like that of the stone, is made up of circular openings. The glass façade is composed of a ceramic fritted first pane that is double run with dual-toned circular patterning and a second pane that is reflective one-way-mirror glass that allows views out while reflecting the patterned ceramic coating of the first pane outward. The result is a glass surface that presents a three-dimensional quality or a shadowed depth that belies its constructive flatness. “From the simplest of regional materials is a strong compositional organization around a commons and garden and a strikingly expressive glass façade that creates a recognizable home for the College of Business that builds identity and community,” said Joseph Tattoni, FAIA, design principal. The home for the Kate Tiedemann College of Business is designed to meet the needs of today’s business-school students. A light-filled central commons and an adjacent Scholars’ Garden support casual learning and encourage productive collisions between students and faculty as they move through the building.

The building applies common sense and technical approaches to sustainable design including the fabrication of furniture from live oak trees found on the site and the use of Forest Stewardship Council certified wood. A building-management system monitors energy consumption, and mechanical systems are designed to minimize energy use while providing optimal comfort control, air quality, and water efficiency. An enclosed sun-lit Scholars’ Garden brings natural daylight into the center of the building. An overhead roof shades the garden and is pulled away from the exterior wall to allow a naturally ventilating outdoor space, thus keeping the Scholar’s Garden cool. This shaded, cool microclimate courtyard affects the general enclosure of the building and reduces the cooling loads on the facility. The challenge of creating a full-glass building in a subtropical environment is to reduce enough solar gain to minimize the cooling load, thereby reducing energy consumption and carbon byproducts. Ikon.5 architects achieved that reduction significantly through modern glass technology, and invented a glazing unit that supported the design intent and performed significantly better than standard glazing units. The firm created an insulating unit that reflected 74% of solar gain and provided 26% transparency by applying a ceramic coating on the second surface of the first side and a reflective one-way mirror surface on the third surface of the second side.

renovation. They completely removed the existing roof, performed structural repairs, and installed 3,400 sq. ft. of a Ludowici French Terra-Cotta tile roof with a bright green finish. The tiles are manufactured by Ludowici Roof Tiles, New Lexington, OH (ludowici.com). The low-profile interlocking clay tile offers an array of benefits for a building. The large size and durable material with deep locks on all four sides, plus two prominent flutes on the surface, provide a dramatic aesthetic and superior drainage. When applied to a roof, these flutes produce a shadow effect for a highly refined, distinctive appearance. Additionally, RSS custom fabricated and installed extensive lead-coated copper flashings. Also installed were new aluminum half-round gutters with custom-fabricated stainless-steel gutter screens to keep them functioning freely on the heavily wooded grounds. Half-round gutters require relatively low maintenance and match almost any style of architecture. The existing tongue-and-groove soffit was completely rebuilt to match the original milled lumber that had deteriorated. Finally, scalloped slate shingles were installed for siding on the prominent front dormers. While slate enhances the look of many architectural styles, when it is cut in a scalloped shape and applied as siding, the material compliments Stone Hall’s Colonial Revival style. This subtle architectural dormer detail delivers a historic appearance. CA

epending on the application, thermally efficient dampers can reduce energy costs significantly, compared to standard dampers. Extrap-
olate that over a hundred dampers in a single building, and building owners can realize substantial savings per year versus the use of less-efficient dampers. Thermally efficient dampers are used in air openings of buildings to control and direct airflow. This function ensures proper operation of heating, ventilation, and air-conditioning (HVAC) systems and minimizes potential heat loss to improve overall building efficiency. In application, thermally efficient dampers can allow airflow between interior spaces but are primarily used in exterior outdoor openings. Given the wide range of applications, dampers can be designed to fit in openings as small as 6 x 6 in. or as large as 12 x 12 ft. and beyond using multi-section assemblies. This type of damper can be applied in many different environments, but they are especially useful in extreme hot and cold ambient conditions. Damper models are available for ambient temperatures ranging from –70 F to 200 F. In cold climates, such as Canada for example, thermal-
ly efficient dampers help reduce heating costs. In southwest U.S. locales such as Arizona and California, they can help cut cooling costs. Typical applications vary from large-area freezers in food-storage facilities to warehouses,

drives to smaller 7.5- to 60-hp pump and fan motors. After each phase, the electric savings amounted to $317,000 and $152,000 a year respectively. “In 2009, our electric consumption averaged 65 million kilowatt hours,” said Sechler. “Now it’s down to 53 million kilowatts. Our peak demand was 16 to 17 megawatts; now it’s 12 megawatts. This is a huge savings that goes right to the bottom line. Altogether, nearly 150 Danfoss VLT drives are producing $1,142,000 in documented annual energy savings. Plus, improved energy efficiency makes the property more attractive to tenants. We’ve been up to 98% occupancy, which is really great in today’s commercial real estate market.” To manage the installation, each drive incorporates Apogee FLN as a software-selectable communications protocol that connects with the building automation system (BAS). The pump drives are controlled using an inhouse Direct Digital Control (DDC), which measures pressure differential across the pump to regulate drive speed. The BAS logs drive performance data and energy consumption, including drive condition. Sechler’s inhouse engineering team is also able to track operational status—and they are delighted that there has been practically no drive downtime since the first one was installed nearly 15 years ago. He also notes that the energy savings from the VLT drives is helping give the building a greener reputation. UPMC recently qualified 17 of the floors it occupies for

Architects undertaking new-construction projects in historic settings typically adopt one of four strategies:

adopts the abstract-reference design strategy. The linearity and composition of the building is inspired by practical concerns (site orientation and access) and symbolic factors such as the original lake shoreline the fort was built to protect. CHALLENGES & SOLUTIONS
Kearns Mancini Architects, Toronto (kmai.com), and Patkau Architects, Vancouver, British Columbia (patkau.ca), faced immense project challenges constructing a visitor center on a site steeped in cultural and archaeological significance. Enhancing the appeal of the fort, while preserving its originality and historic foundation, posed a particular challenge. To respect the sensitivity of the site, the architects envisioned a long, linear building form, tucked underneath the massive nearby Gardiner Expressway. Submerging the new structure into the landscape would further align it with Fort York’s topography and history. According to Dan McNeil, project architect with Kearns Mancini Architects, “The approach to the visitor center is underneath the Gardiner Expressway, which is a very large and powerful singular architectural statement, forming an almost cathedral space underneath. Rather than competing with this grandiose structure, we conceptualized a subdued yet distinct building, which metaphorically connects with the fortifications and historic tapestry of the fort. We also decided to construct a transitional zone within the proposed building, creating an ascending viewing platform.” THE CHANNEL-GLASS CHOICE
The original plan was to project battle-scene images on a projection/display cladding surface. That approach was not economically feasible, leading to the selection of Lamberts channel glass manufactured by Bendheim Wall Systems Inc., Wayne, NJ (bendheim.com). The material was selected for its structural capacity and light-diffusing properties and the resultant savings of more than $1 million. McNeil remarked, “This illuminated structure seems to Channel glass, used in the Fort York visitor center design, provides a sculptural quality and allows back lighting that creates a soft glow.

clad structure. The channel glass becomes a part of the architectural “ramp” that ascends from the common grounds to the upper level, creating a viewing platform to the fort. According to McNeil, “The selection of the glass was to give a sense of sculptural quality to the part of the building that emerges into the main plain of the site.” Bendheim’s frame design removes the need for vertical metal supports, allowing walls of uninterrupted channel glass, including glass-to-glass corners in a variety of angles. Tempered safety channels, pocket-set into the frame system, create the backlit façade. Highwind-load specifications required strategically positioned mid-point wind clips to achieve continuous vertical spans as high as 20 ft. and eliminate the need for horizontal stack joints. The sloped terrace of the visitor center consists of two parallel single-glazed channel-glass systems, allowing one side of the glass wall to terminate at the terrace, while seamlessly bypassing it on the opposite side. Lighting fixtures, attached to the back of the glass system, illuminate the facade at night, producing a soft glow. The glass also contributes to sustainability. It is made with more than 60% recycled material, including an estimated 40% post-consumer content. The material is manufac-

Speedway Improves Track Views Window film reduces heat and glare to offer race viewing.
T
he Speedway Club at Charlotte Motor Speedway, Concord, NC, is said to be one of the best places to take in the NASCAR experience. The private club and its 57 suites offer exceptional views of
the famous racetrack through their 60-ft.-high windows. The windows are the club’s greatest assets, but the hot sun disrupted race fan comfort during sporting events and other functions. The sun brought in a great deal of heat and, during certain times of the day, cast a terrible glare into the club. The glare interrupted race viewing and made it

difficult to enjoy a relaxing lunch. The challenge was clear: get rid of the glare and heat coming through the large expanse of windows.
Below. More than 1,200 sq. ft. of window film provides balanced solar performance with the natural appearance of glass and has dramatically reduced the glare and heat inside the club at the Charlotte Motor Speedway. Images: Charlotte Motor Speedway
The solution was also clear: window film. Club management chose to professionally install film on 1,272 sq. ft. of windows to ensure member comfort regardless of the weather. Madico Window Films’, St. Petersburg, FL (madico.com), Sunscape Purelite 60 film was installed. An extremely light architectural window film that provides balanced solar performance with the natural appearance of glass, the film allows excellent solar protection and has dramatically reduced the glare and heat inside the club. The film creates a crisp, fresh view from the inside and outside. Once the benefits were outlined, it was determined that the film would meet all the needs of the members, while maintaining the exceptional aesthetics the club has carried since its inception. Although the club is open year-round for lunch, dinner, and events, most of the NASCAR races take place at night. Management needed to ensure their selection of Purelite 60 would also work well under the lights. The film produces no reflection or distortion when the sun goes down. Club members can view the afternoon trials from the climate-controlled club without any glare, as well as the evening races with the best seat in the house, reflection free. “The new Purelite 60 film has really helped to reduce the heat coming through the windows of our Speedway Club ‘The Greatest Place to View the Race,’” said the club’s general manager George Kail. “Our fans can now look out over the World’s Greatest Speedway in even better comfort.” Along with member comfort, the window film also provides energy efficiency and safety. Due to the reduction of heat and glare, the club’s HVAC unit works less. Blocking 99% of UV rays, the film also alleviates sun damage. All Pro Window Tinting, Canton, GA, installed the film on 24 windows. The job took a day to complete and began to show results as soon as the installation was finished. CA 48

emours Alfred I. duPont Hospital for Children, Wilmington, DE, recently completed a 557,000-sq.-ft. hospital expansion. The $272.8-million project included 144 single
patient rooms, 44 emergency-department exam rooms, and 200,000 sq. ft. feet of nora, Salem, NH (nora.com/us), premium rubber flooring. Since then, project-team members, including the project manager, designer, construction manager, nurse manager, and environmental services (EVS) operations manager, have used a post-occupancy evaluation (POE) to study the contributing factors and outcomes the flooring selection has had on clinical efficiency. A POE includes collecting data and obtaining feedback on a building’s performance when it is in use. At Nemours, the evaluation used Hospital Consumer Assessment of Healthcare Providers and
Systems (HCAHPS) scores, as well as feedback from caregivers, patients, and families. The results are proving invaluable as a reference for making informed decisions regarding the built environment. As a structural component of the building, one that covers every square inch, flooring greatly influences the entire palette of products selected. But what influences the choice of flooring? At Nemours, a number of factors contributed to the final selection of premium rubber flooring for large portions of the hospital. Such factors included Above. Nemours Alfred I. duPont Hospital for Children, Wilmington, DE, completed a 557,000-sq.-ft. hospital expansion.

acoustics, staff fatigue and retention, health and safety concerns, operational optimization, environmental considerations, and life-cycle cost analysis. Environmental factors, such as infection control and safety, were part of the material-selection strategy. Additionally, the ability to create zones through the use of color played an important role, particularly for the design of a children’s hospital. A “pattern with purpose” discreetly designated patient, caregiver, and family spaces within the patient rooms. PERFORMANCE CRITERIA
Using a mock-up, strategically located in an everyday-use location, the hospital conducted a fair evaluation of flooring products under consideration. The mock-up played a critical role in the selection process. In any project of this magnitude, a variety of stakeholders want to provide input—patients, families, nurses, design-team members, facility managers, administrators, and environmental services employees. Mock-ups provide a means for them to have a voice in the design and selection process. At Nemours, more than 250 clinicians and staff members provided feedback regarding the various flooring choices installed. Specific performance criteria used to evaluate floor coverings centered on assessing durability, maintenance, safety, sustainability, ergonomics, and acoustics.

interiors The absence of finishes and chemicals also means patients will not need to be moved, or large areas of a facility closed for an extended period of time, while floors are cleaned and coatings or finishes are applied and allowed to dry. This time savings is especially important for flooring that supports patient outcomes, as healthcare facilities operate 24/7, 365 days a year. Informed flooring decisions support operational optimization and clinical efficiency. The chemical-free cleaning process also allows faster patient-room turnover. Nemours has experienced a marked decrease from 4 hours to 45 minutes to turn over a patient room and attributes much of this operational optimization to the ease of caring for rubber flooring. Return on investment. The simpler maintenance regimen for premium rubber flooring has resulted in an 11% decrease in the annual cost of floor-cleaning supplies at Nemours. This translates to annual savings of $31,000, which goes right back to the health system. Additionally, the hospital reports a reduction in overtime hours for care and maintenance of floor coverings, and a 75% labor-efficiency increase has been realized and is attributed to nora premium rubber flooring.
