The greatest chromaticity (i.e., color temperature) shift was noted in retrofit kits installed in halogen wallwash luminaires at the University of Maryland’s performing arts center. By the third measurement round (after at least 12,000 operating hours), the sampled products had a color shift value—expressed as ∆u’v’- that averaged 0.0118, significantly above Energy Star’s 0.007 standard. However, the fact these fixtures—installed in ceilings as high as 41 ft.—had operated 17,000 hours without need for replacement has sold facility staff on LEDs, versus the old halogen lamps, with their rated lifespan of 1,500 hours. The university has completed LED conversions in several other buildings, with reduced maintenance leading energy savings as a prime motivator.

ILLUMINATED ART: MILAN DESIGN WEEK
Sensing the Future Japanese designer Tokujin Yoshioka lit up Milan’s Design Week this past April with an art installation exploring the use of OLED panels from LG to reflect how we see and feel in today’s technology-driven world. Visitors to the exhibition titled “Senses of the Future” were able to view and sit in 17 “S.F. Chairs,” which had the profile of a standard piece of furniture, but were constructed of doublesided OLED panels. Providing a continuous show of vividly flashing light, the chairs were intended as a meditation on the speed of modern-day life. This piece incorporated nearly 30,000 individual LG OLED light modules to create an undulating simulation of the comfort and warmth experienced on bright sunny days.•

Gold on a Budget In creating a new front door to the University of Chicago’s campus, the design team for the school’s North Residential Commons were briefed to aim for LEED Gold status while holding to a tight budget. For lighting pros with Lightswitch Architectural, this meant a close collaboration with architects from Studio Gang to incorporate LED-based solutions into the project’s many unique design elements. In the study room, for example, fixtures housed within the coffers of the wooden tray ceiling both highlight the coffers’ depth and provide soft ambient illumination for students, below.•

HUMAN CENTRIC LIGHTING: DYNAMIC LIGHTING
What About Light Variation and HLC? While color tuning was one of the hottest topics discussed this past Lightfair, dynamic lighting is another trend that’s worthy of discussion, particularly in context of human centric lighting. In this issue’s Market Setting Feature, Kevin Willmorth expounds on the top 10 trends he sees coming in the next 10 years. One is for more scientific study of the impact of light on humans. In a conversation pre-dating the story, Willmorth was skeptical of the benefits of color-tuning alone, but he did see potential value in more randomness of light as a possible stimulus, wondering, in fact, if interior light being contrary to exterior conditions might have a greater impact. The good news is there are products doing just that: Philips, at NeoCon last year, debuted its Luminous Patterns line (right), while Acuity, at Lightfair ‘16 debuted Rubik. Add this topic to the HLC list to study. •
INDUSTRIAL: SCHWERIN POWER PLANT, GERMANY
Towers of Power As the Schwerin South power plant in Schwerin, Germany, was transformed from an oil-burning facility to a combined heat and power, biogas-based plant, its operators wished to visually celebrate this move to a cleaner, future-focused fuel source. Calling out the plant’s varying geometric forms, such as the domed biogas tanks and vertically linear stacks, designer Thomas Römhild specified several fixture types from LED Linear, including the narrow XOOLUM and flexible VarioLED Flex VENUS luminaires. Complicating the project was a design goal to limit light pollution and energy use. The luminaires are placed to illuminate structural surfaces, not the night sky, and a dimming protocol varies lighting brightness from early evening through to later hours, and then turns it almost
ABOVE: In order to reduce the effect on the inhabitants—but also for the insects and birds—the luminaires were arranged in such a way that they do not emit light into the sky, but specifically illuminate the surfaces. Due to the small design of LED luminaires, it is possible to adjust the light precisely or to install the luminaires in an appropriate way.

EDITOR’S NOTE
As Kevin looks forward into the next decade, we briefly look back in this montage of statement projects that have marked SSL’s progress.
IN THE BEGINNING
Back in our first issue, in May of 2007, we covered Discovery Communication’s HQ in Silver Springs, Md. Designed by Jeff Gerwing and Rodrigo Manriquez of SmithGroup/JJR—early LED adopters—it represents one of the first major plunges into SSL, mostly in the form of RGB facade illumination.

Controls under Control The growth of controls integration into modern lighting systems will explode, while the underlying architectures employed will be reduced. This will end conventional controls in favor of digital interfaces. The current cacophony of components, proprietary and open source protocols, system backbones, complex connections, confused commissioning demands, forced obsolescence, and lack of a uniform widely applicable standards will come to an end. The future of lighting control operation depends on the demise of the five-decades old battle for supremacy that is responsible for the dysfunctional condition lighting controls now suffers. The current trend of multi-platform agreements, such as cooperative relationships between Zigbee, Bluetooth, Enocean and BACnet point the way to a more uniform, universal, and accessible future. This is critical to achieve the goal of coordinated building automation, and connectivity outside building walls through the Internet of Things.

IN TRANSITION Lobbies, atriums and hallways can adapt to or interpret the end use of the structure around it. Each transitional element presents its own energy level—small, medium, large and everything in between. Their story line, even if experienced briefly, expresses the talent and intellect that went into its creation. The examples presented here are some of the many projects we’ve reviewed that demonstrate how, for public spaces, attention to spatial definitions, material relationships and the applied technology of lighting can communicate, like characters in a story.

Airland Shenzhen Location: Shenzhen, China Architect: BLVD International When architect Honglei Liu of BLVD International accepted the commission for the renovation the Airland Shenzhen Hotel, a small resort located on the Dameisha Golden Coast in China’s eastern Shenzhen Coast, she knew her challenges were daunting. One was the tight budget. Another was to give the main atrium space an upgraded visual image. She introduced a curvy architectural aesthetic, a pale color palette and a reflective background for the balconied space. Daylighting expands the visual perspective of the space and adds an upscale atmosphere. She took inspiration from the nearby sea by suspending over the main lobby’s seating area a school of small glass fixtures in the shape of fish. The effect, both artistic and functional, adds a touch of whimsy to the otherwise basic environment. Another Liu touch is the buffer zone between the atrium and the hotel’s adjacent restaurant. Here, she created a screen of natural bamboo, with attached illuminated swimming creatures spaced along its length.

The era of inventing society-changing electronics in drafty suburban garages has been relegated to technology history. Now, it’s all about encouraging innovation in distinctively innovative settings, including adaptive reuse of former industrial buildings. At Utrecht University, the strategy to encourage innovation for its Life Sciences Incubator (LSI) in the Utrecht Science Park was to retain Mecanoo, and tell the renowned architectural firm to infuse the entire interior with a signature brand of visual creativity. Containing offices and laboratories, the exterior of the five-level, 67,000-sq.-ft. building has a slanted façade with solar control glazing that acts as a natural sun and heat block. In the open central atrium that is 195 ft. long, 46 ft. wide and 62 ft. high, the horizontality is expressed by the linear detailing of the contrasting bands of extended wood slats that mark the interior floors. The seemingly gravity-defying open staircase is a visual as well as physical connector and makes an implied statement for personal achievement. Lighting fixtures are installed at the ends of the curved wooden slat ceiling. Downlights are attached to the wooden laminated roof beams as well as the ceiling.

Shinsegae International Building Location: Seoul, South Korea Lighting Designer: TinoKwan Lighting Consultants At a height of 15 stories and a gleaming glass skin, the 168,000-sq.-ft. headquarters for Shinsegae International makes a contemporary statement amidst smaller buildings in this commercial section of Seoul. Interiors for the public spaces occupied by the firm, which is a major developer of stores for the fashion industry, express an environment of elegant style and deft use of patterns and materials. Daylighting via tall multi-grid windows is a major source of illumination in the rectangular structure. In the main elevator lobby, the design architects, Olson Kundig, repeated the geometry of the window mullion patterns with wood for the main walls and on the accent walls composed of separated horizontal elements. Above, recessed fixtures in the dark paneled ceiling are positioned in straight rows. For a double-height meeting/presentation room, similar recessed fixtures are spaced in the light color stepped-down ceiling. Lighting was created by TinoKwan Lighting Consultants. The building was a winner in the 2017 American Architecture Award program for the best new buildings designed and constructed by American architects in the U.S. and abroad.

OVO Wroclaw Location: Wroclaw, Poland Lighting Supplier: Philips Lighting Seen from the air, the mixeduse OVO Wroclaw resembles an imposing white ocean liner with a rounded prow. Located in the center of Wroclaw in southwest Poland, the eight-story building contains apartments, a Double Tree hotel, offices, a casino and fitness club. The outline of the open central court follows the structure’s curved theme, as does the lighting for the interior spaces. Philips Lighting supplied LED fixtures for the exterior and public areas. For the hotel lobby featuring a curved reception desk framed in white, four graduated rows of LED strip lights are beamed downward to the work surface. Circular recessed fixtures echo the outlines of the seating and small white-topped tables. In the ballroom, the geometry of the circle has been split into four sections above the round dining tables. Custom light output is adaptable to the complex’s facility managers remotely with an LCG touch panel screen. Kelvin range for the public spaces ranges between 2700K and 3000K.

Merchandise Mart Location: Chicago, Ill. Lighting Supplier: PureEdge Chicago’s iconic Merchandise Mart offers a total of 4.2 million sq. ft. for rent in its monolithic site along the Chicago River. Long recognized as the national epicenter for showrooms occupied by firms representing myriad sources of products for commercial and residential interior environments, tech companies have now taken up significant residence in the 25-story-high, 87-year-old building. Approximately 1.5 million sq. ft. of office space is now dedicated to technology businesses, employing 10,000 workers in the Mart. To keep visual pace with its new cadre of occupants, the Mart management invested $40 million in upgrades to make the creative community feel at home. Contemporary LED lighting from PureEdge provided customized linear lighting fixtures that are both decorative and sculptural were installed on eight floors. Installed in the hallways and elevator bays, the firm’s linear suspension lighting and plaster-in systems support the new contemporary esthetic. PureEdge also was selected for the Mart’s new food court area.

San Francisco War Memorial Veterans Building Location: San Francisco, Calif. Lighting Design: Auerbach Glasow French Although completed in 1932 when the angular expressionism of Art Deco was the encompassing design mode of the era, the architecture of the San Francisco War Memorial Veterans Building was classic Beaux Arts. Following a nearly five-year planning, design and installation process, Auerbach Glasow French provided architectural lighting design for the colonnade exterior and all interior public spaces, including performance spaces, lobbies, the exhibit area and offices. Engineer of record for the project was Simpson Gumpertz & Heger. The upgrading of the building’s Herbst Theater was carried out by Auderbach Pollock Friedlander, theatrical facility specialists. An extensive initial inventory of hundreds of original fixtures was followed by a comprehensive schedule for restoration and upgrading, primarily utilizing LED lamps. Chandeliers in the ground level main lobby now allow the space to hold events with the installation of separate circuitry for function configuration. For the double-height Green Room, formerly the library and now used for events, five 24-lamp chandeliers, similar to those in the Herbst Theater, were refurbished and made controllable.

T-Mobile Signature Stores Chicago, New York, Miami and Santa Monica Focus Lighting Design Team Principal Designer: Brett Andersen Senior Designer: Valentina Doro Project Manager: Jon Blitstein Architect: FRCH Fixture Fabricator: Fleetwood Audiovisual: AVI Systems Text: Ellen Lampert-Gréaux The Challenge: Imagine a base, but modifiable, lighting design for a series of flagship outlets for T-Mobile that would occupy marquee real estate at key locations across the country, yet still reflect each store’s urban setting. Longevity and maintenance were top concerns, but so were aesthetics, as branding was a big part of this initiative. The Solution: LED, in the form of linear, track, panels, accents, and even millwork-integrated linear, proved the only solution flexible enough to meet both service and aesthetic needs. “It’s definitely a major trend to use LED in retail,” says Brett Andersen, Focus Lighting’s lead designer on the project. “Prior to LED, the prime sources were metal halide or MR16s. But with the 50,000hour lamp life, the LED has taken the lead and has a great advantage for retail installations. There’s no going back.”

In Miami, a large kinetic chandelier, custom-designed by AVI, as well as geometric LED panels, reflect the city’s budding arts community. The most recent of the chain’s stores, in Santa Monica, opened in February 2017 and is all about nature. This theme allowed the designers to bring in more ambient natural light via a skylight. “It kind of feels like you are in a park,” says Andersen, who also significantly increased the store's ambient light to make it feel more like the outdoors.

The LED fixtures also help illuminate product displays. “We wanted to make sure the lighting would continue to look good, especially on displays as they continuously change,” notes Andersen. “We looked for every opportunity available to use non-adjustable fixtures, reducing the need for re-aiming.”

LANDSCAPE LIGHTING AT OBSERVATORY INFLUENCED BY THE STARS AND PLANETS TROTTIER OBSERVATORY Simon Fraser University, Vancouver, British Columbia
Heavenly bodies that cast their glow on admiring earth dwellers below have been celebrated in the fine arts for centuries. In music, works such as The Planets, by Gustav Holst; Hoagy Carmichael’s Stardust; and the show Lost in the Stars, by Kurt Weill, have become part of the celestial repertoire. Now, at Trottier Observatory at Simon Fraser University near Vancouver in British Columbia, the lighting design of the facility, by the Integral Group and landscape architecture by PWL Partnership Landscape Architects, seeks to translate the beauty of the night sky in a contemporary sculptural setting. Bold and dramatically dimensional, illuminating technology is combined with singularly expressive landscape design to make the observatory its scientific centerpiece. The site, 12 miles from sea level at Vancouver, rises to a height of 1,200 ft. at the Burnaby Mountain campus of SFU. Named after the 19th century Scottish explorer who built the first European settlement in BC, it was established in 1965 as a public research university. The $3.4 million Trottier Observatory and Science Courtyard, completed in 2015, was designed by PWL working with SFU departments and physics professor Dr. Howard Trottier. His eponymous family foundation contributed $2.7 million to the development of the project. Popular response to the outreach program has drawn members of the Vancouver community to the observatory’s public telescope so they can view far-distant galaxies, and electrical outlets to allow visitors to set up their own telescopes. Sponsored by the observatory, Starry Nights

THE CHALLENGE: Integrate the observatory and surrounding grounds with the grid originally established by Canadian architect Arthur Ericson for the campus. The secondary goal was to create a courtyard where scientific learning and a connection to nature could occur. The designers also wished to extend the emphasis on learning and place from daytime into the evening. Finally, the team wished to encourage exploration and discovery by all users throughout the year. Lighting was to add dimension to the constructed elements and not interfere with the observation of the nighttime sky. THE SOLUTION: Fundamentals of astronomy and physics were introduced into the landscape and lighting programs. The designers placed a story line plinth positioned with detailing derived from logarithmic scales of the human body and space. According to the designers, it represents the science of spectroscopy, the backbone of all astronomical knowledge. Black benches signify dark stars and radial planting represents the orbit of the planets within the Earth’s solar system.
