interest in acoustics and the role that design factor plays in occupant comfort, communication, and productivity. In 2019 we will be providing year-long coverage of that topic, through articles and podcasts, designed to help you better understand the science, design principles, and the impact good acoustics have on occupants. Our expert is Gary Madaras, PhD, ASA, INCE, Assoc. AIA, and acoustics specialist at Rockfon, Chicago. The first installation in this series starts on p. 18 and focuses on how to evaluate acoustics needs/performance in various areas of healthcare facilities. It is accompanied by our first podcast with Madaras in which we talk about acoustics as they pertain to people with impaired hearing and those who use English as a second language.

Outdoor Care Retreats Offer Respite I
n the peaceful ambience of the forests only a short walk from two of Norway’s largest hospitals, Oslo-based architectural firm Snøhetta designed secluded
wooden shelters to make hospitalization easier for patients and their families. The Outdoor Care Retreats offer visitors a physical and psychological respite from stringent treatment regiments and the isolation that often follows long-term hospitalization. Leaning toward the lush forest and the trickling Sognsvann creek, the Outdoor Care Retreat is located several hundred feet from the entrance of Norway’s largest hospital, Oslo Univ. Hospital, Rikshospitalet. Its sister building is situated in the deciduous woodland by Sørlandet Hospital, Kristiansand, in the south of Norway, between oak trees and birch, overlooking a nearby pond. Originally developed in collaboration with the Department of Psychosomatics and CL-Child Psychiatry at Oslo Univ. Hospital, the Outdoor Care Retreat provides a peaceful space where visitors can benefit from the therapeutic qualities of nature. “Nature provides spontaneous joy and helps patients relax. Being in natural surroundings brings them a renewed calm that they can bring back with them into the hospital. In this sense, the Outdoor Care Retreat helps motivate patients to get through treatment and contribute to better disease management,” said child psychologist at the Oslo Univ. Hospital, Maren Østvold Lindheim, one of the initiators of the project. The space can be used for treatment and contemplation and for spending time

with relatives and friends away from the hospital corridors. The cabins are open to every patient connected to the hospitals, regardless of disease group, and reservations are managed through a booking system. The subdued 375-sq.-ft. spaces stand in stark contrast to the monumental hospital buildings with which they are affiliated. Referencing the playful construction of wooden tree cabins typically made by children, the luminous cabins are formed like skewed blocks of wood that extend into the landscape through asymmetrical branches. The massive wood of the main structure of the cabin will turn gray over time, blending naturally into the surroundings. Following Snøhetta’s commitment to socially sustainable design and public space, the cabins are accessible for wheelchair users, and the angled entrance of black zinc is large enough to make room even for hospital beds. The cabin consists of a main room, a smaller room for conversation and treatment, and a bathroom. The interior is fully clad in oak, echoing the natural material of the woodlands outside. Inside the space, colorful, sculpted pillows can be moved around freely, allowing children to build huts or lie down to gaze at the canopies through the circular window in the ceiling of the main room. The cabin’s large glass windows can be fully opened, inviting nature into the space. In this way, visitors can peek into the woods, smell the damp forest floor, and listen to the sound of trickling creek water while still being inside the cabin. Although the cabin is integrated in the hospital campus, its secluded location and natural aesthetics allow it to be perceived as a place of its own. It is a place of muted magic, a place out of the ordinary that provides a generous and much-needed breathing space for visitors of all ages. The vision is to build more Outdoor Care Retreats in the vicinity of hospitals in Norway and abroad. The cabins are always adapted to the specific location in a way that requires minimal intervention in nature. The cabin consists of a main room, a smaller room for conversation and treatment, and a bathroom. The interior is fully clad in oak, echoing the natural material of the woodlands outside.

very aspect of the design for Duke Integrative Medicine, Durham, NC, reflects the program’s transformational approach to healthcare.
Program spaces for traditional and alternative medicine are united through a rich use of natural materials, such as wood and stone, and a focus on the patient’s procession through the spaces. Generous views of interior and exterior gardens and numerous spots for reflection and contemplation evoke notions of mind, body, and spirit. Nestled in the woodlands of Duke Forest, this holistic environment is welcoming and comforting. The realms of nature and man-made— reflecting the facility’s dual use of holistic therapies and medical science—are interwoven through visual and physical connections. The orchestration of light, transparency, translucency, openness, and scale define the building’s program spaces including therapeutic treatment rooms, workshop and meditation spaces, a library, fitness facilities, and a state-of-the-art café offering healthy cooking demonstrations, guest meals, and catered events.

DUKE UNIV. STUDENT WELLNESS CENTER
T
he Duke Univ. Student Wellness Center, Durham, NC, weaves health and wellness together into everyday student life, with student health, nutrition,
counseling and psychological services, and wellness and case-management programs coming together under one roof. The new facility answers the needs of clinical care and expands the role of wellness in ensuring healthy students. Strategically situated between athletics, student services, and residential complexes, the building abuts Duke historic forests and a primary campus circulation path. The design’s transparent two-story entry brings natural light into the building and allows views of the outdoors. To minimize the project’s environmental impact, oak harvested from the site was used extensively for interior surfaces and exterior seating. A contemplative garden reinforces connections to nature and extends to campus pathways. A monumental entry stair follows a translucent wall through the lobby to celebrate the intersection of care, prevention, and social interaction in achieving wellness. Public and private functions are layered—the entry is open, but presents circulation options for students seeking care, privacy, socializing, or wellness programs.

Trends Shape Lighting Design Tips for integrating natural light with artificial light. Omar Rivera, LEDVANCE
A space’s visual appearance is heavily dependent on how it is lighted. Intensity, direction, uniformity, and spectral distribution determine light quality. Natural light presents a highly variable but potentially very high-quality light source to the mix. Special care should be taken to ensure the natural light and electric lighting work together to best serve a space’s task and aesthetic needs.

| lighting remote user control and overall convenience. Maximize daylighting distribution. Natural light can enter a building through sidelighting or toplighting, the design of which allows architects to control its quantity and quality. Generally, natural light should enter a space from as high a vantage point as possible and cover areas where users need it. To maximize usable daylighting area, perimeter zones can be increased. Features such as light shelves can push the light deeper into a space while also diffusing it. Automatic devices, including heliostats, can maximize usable daylight. ARTIFICIAL LIGHT
Artificial electrical lighting may be considered as three functional layers: task, ambient, and accent lighting. Natural light generally provides ambient lighting and is integrated with that layer. The design goal is to provide quality illumination that has a seamless look and feel— in other words, ensuring a space that looks great with natural light and without. The way to accomplish this is to establish clear illumination goals for each space and to merge natural light with artificial electric light into a cohesive design, resulting in a high-performance and This is a suitable application for daylight harvesting to save energy and comply with energy codes. General lighting could be zoned as two separate parallel rows of downlights (and possibly a third, depending on natural-light penetration). Each control zone could be switched, although with the seating, it may make more sense to step-dim for user comfort. In this case, high levels of bright natural light and glare during certain parts of the day can be mitigated with wireless window treatments, which are also highly recommended in work areas that contain computers screens.
integrated system. Electric light should match natural-light patterns. Natural light may not uniformly cover an entire space. Instead delivers gradients of intensity reaching into the space. General lighting should be placed parallel to the natural light, allowing luminaires to turn off or dim when sufficient natural light is available. Otherwise, the electric lighting should place light on the same surfaces as the natural light. If the natural light is distributed on walls and ceilings (as is often desirable), the electric lighting should do the same. Note that some variation in light levels over the course of the day may be acceptable and even preferred, but surface brightness should remain relatively consistent. Use light-colored surfaces, with brighter surfaces kept out of the line of direct sunlight. Match the color quality. Specify the light source with a neutral- or cool-white correlated color temperature (CCT, typically 3500 K to 4100+ K). Otherwise, if a warm-white CCT (<3500 K) is specified, the light emission, when mixed with very cool daylight (>5000 K), may make the light sources appear yellow. Consider supplemental lighting. Be aware of contrast between areas and surfaces receiving natural light and those that will not. In deep spaces, consider wall washing or accent lighting on rear walls. In spaces where natural light provides insufficient light on ceilings, such as spaces with skylights, consider luminaires with some uplight distribution. CONTROLS

Contemporary interior LED pendant Verner pendant: • Contemporary LED luminaire • No visible hardware • High-ceiling applications
The Verner pendant is a deco-performance fixture that combines high light output with a geometric aesthetic to enhance interior spaces while providing useable light. With no visible hardware, the pendant can be used in high ceiling applications, open areas, or spaces where diminished focus on the ceiling is the aim. The luminaire’s contemporary look is completed with a classic spherical diffuser. The cone-like shade ensures that light is directed downwards and is suited to applications where designers want to avoid indirect light illuminating the ceiling. For applications where a high output of downlight is required as much as a decorative element, the LED light source delivers 2,400 lumens in the standard version and more than 4,200 lumens in a high-output version. Available in 3000 K, 3500 K, or 4000 K, the pendant can be cable or stem mounted. The standard exterior finish is black or white as standard, while the shade interior is white for optimal light reflection. Eureka, Montreal Circle 50 eurekalighting.com

Combination, heat-only boilers AquaBalance Series 2: • Wall-mount combination/heat-only boilers • Titanium-infused heat exchanger technology • Retrofits or new construction
AquaBalance Series 2 wall-mount combination and heat-only boilers have an energy-saving AFUE rating of 95%. The updated units combine the warmth of high-efficiency space heating with the convenience of on-demand domestic hot water (combi version) in a reliable, space-saving, and reportedly easy-to-install package. The units use stainless-steel, titanium-infused heat exchanger technology, with applications for retrofits or new construction in apartments or condominiums. The boilers are available in 80-, 120-, and 155-MBH input, in combi or heat-only versions. The 155-size combi-boiler produces a constant supply of hot water of 4 GPM at a 70-deg. F temperature rise. The unit has the power to supply hydronic heat for as much as a 2,500 sq.-ft. area. Weil-McLain, Burr Ridge, IL Circle 58 weil-mclain.com
Pre-treatment for evaporative equipment
Good chemistry.
Water Saver is a capacitive deionization pre-treatment system to improve the efficiency of heat transfer and water efficiency for evaporative cooling systems. The capacitive deionization technology reduces dissolved ion concentrations to lower makeup water conductivity prior to use in evaporative cooling systems. Dissolved ions are removed from make-up water as they are attracted to the charged capacitors. The system improves water efficiency by increasing operating cycles of concentration, reducing blowdown and the use of treatment chemicals. Evapco Inc., Westminster, MD Circle 59 evapco.com

Not Just A Floor Fitness facility matches flooring choices to activities for an optimal experience.
G
ymNation’s first fitness facility in Al Quoz, United Arab Emirates, offers a wide array of programs and equipment options to ensure a pleasant experience for first–time gym-
goers as well as the most dedicated athletes. The 40,000-sq.-ft. facility features specific zones for each exercise— weight lifting, plate-loaded, free weights, cardio, boxing, CrossFit, functional fitness, running track, and group fitness classes. The facility includes a 4,000-sq.-ft. group-exercise studio, an 1,800-sq.-ft. spinning studio, a section for personal trainers, and, to meet Middle Eastern culture demands, a ladies-only gym with a 3,000-sq.-ft. area of Matrix fitness equipment. GymNation CEO Loren Holland partnered with Johnson Health Tech ME, Taichung City, Taiwan, to specify and design the facility from top to bottom. A key component of the facility’s design included the specification of resilient flooring from Ecore Athletic, Lancaster, PA. “Selecting the right flooring for each area of the facility was paramount to assuring an optimal experience for guests,” said Holland. Johnson Health Tech ME, the sole supplier of fitness equipment for the GymNation project, recommended Ecore Athletic flooring in the early stages of the design process. The Johnson team worked to create a cohesive space while selecting specific materials and equipment for each

zone. “Working with our design team, we proposed the appropriate products to meet client expectations in terms of quality, performance, force reduction, and energy restitution based on the equipment and exercise programs,” said Mohamed Fetouh, regional key account manager with Johnson Health Tech ME. Ecore flooring products incorporated throughout the facility include:
• Bounce 2, a synthetic wood-grain surface fusion bonded to a 5-mm base layer picked for the group exercise studio to support constant movement and feet pounding
• Everlast, a vulcanized composition-rubber product for areas focused on cardio, functional fitness, personal trainer work, and walkways
• Speed & Agility Turf, a textured-nylon wear layer installed to create the natural feeling of running outside and for sled work, marking the first time this material has been used in a UAE fitness facility
• Performance Rally, a 2.5-mm wear layer with a 12-mm shock-absorbing base layer selected for free-weight areas, due to the thickness and density level that provide higher force reduction and energy restitution
• Spectator, a 2.5-mm luxury vinyl tile chosen for the spinning studio. For Holland, choosing the right flooring material was a top priority for realizing the design vision. “It is not just a floor. We consider flooring as important of a product in the gym as any other piece of equipment, all equally contributing to the success of the services we provide,” he said. “While our members really enjoy the overall experience in the facility, our running track has collected the highest score in our member satisfaction surveys.” CA

ascade Architectural, Tualatin, OR, provided 4,000 sq. ft. of 1/4-in., 16-gauge stainless-steel fabric for a new parking garage on the campus of HCA Healthcare, Nashville, TN. The coiled-wire fabric defines the architectural style of
the parking garage and conveys a clean, modern aesthetic. The site of the parking garage is in an urban overlay zone, requiring the building’s design to abide by a specific set of urban overlay standards. The standards required that the garage have an articulated façade to minimize the visual impact of the structure and add life to the street. Fabricoil coiled-wire fabric secured in a Borderline attachment system—a perimeter only, powder-coated carbon-steel frame with top and bottom rods that tension the fabric—was used for the project.

The company provides a field installation kit that includes instructions and all mounting hardware. Installation requires drilling eight holes in the frame for the hinges and the support brackets and drilling two more holes in the cover stiffener for the hold-open latch. A pintle hinge design allows the panel to open to a full 90-deg. position to maximize the area available for access.

asked with restoring the historic White Building’s lobby in Buffalo, NY, the interior designers at Carmina Wood Morris DPC, Buffalo, chose Chicago-based StonePeak Ceramics’ Plane Calacatta Vena Classico for its dramatic marble impression and large panel size. The basket-weave floor installation dynamically disperses the product’s beautiful veining, and full wall tiles celebrate the pattern’s exquisite complexity. Matte and polished finishes combine to create texture in a lobby exemplifying modern luxury. Photo credit: Tessa Santillo
