ARCHITECTURAL SSL • Chronicling the Advancement of LEDs in the Built Environment

WINNERS AND LOSERS IN THE GREAT SOLID-STATE REVOLUTION It’s not a revolution if nothing changes for anyone. The purpose of revolution is to move from one paradigm to another. SSL, it’s safe to say, has been a disrupter to conventional lighting, but who has come out victorious, and who’s gone down in the fighting? At least one winner is the planet Earth. [Page 16]

SSL BUZZ Six tips to better illuminate spaces to address health and comfort; Going all-in on Bluetooth; Making people ‘nicer’ with light technology.

"While it was once argued that solid-state technology was just another light source, it is now clear that something far more revolutionary is afoot.

What has been, can be, and will be done with SSL, including soon to emerge technologies within this category, will continue to cement this observation."

Among the researchers’ conclusions is the need for specifiers to seek out details on the specific fixture they are interested in ordering, rather than counting solely on family-wide data in listing resources, as such databases can end up reporting the performance of a wide range of products under the tested performance of that product family’s best-performing member.

Additionally, researchers emphasized other attributes, including glare, could be just as important as efficacy on a given installation.•

Part of SSL’s growing evolution has been a greater acceptance and adoption of controls to enhance and better realize much of LED’s unfulfilled potential.

Some protocols are beginning to come to the fore...

standard with Bluetooth Mesh—it’s this latter fact, according to LEDRA’s director of sales and marketing, David Derks, that’s been a major reason the company has jumped on board. “If you look at the other protocols, none of them have standards at the application layer.”

Bluetooth Low Energy, he adds, is very energy efficient, especially with its ability to use EnOcean’s standard wireless wall switch using only kinetic energy to control. Wireless, he believes, is here to stay, and legacy technologies will have to acquiesce, sooner or later, either through development, or by acquiring startups/ patents. “This could very well be like fluorescent manufacturers fighting LED 8 years ago,” says Derks. “The Internet of Things is a real phenomenon and is moving forward.”

While he admits it’s going to take time for IOT to actually become interoperable, the Bluetooth standard, he argues, currently gives the community the best shot. “Putting a bet on Bluetooth is a short putt, and a far better bet than smaller residential home-spun systems you find in big box stores and residential lighting showrooms.”

LEDRA’s ALPHABET line, including the Vector downlight (a 2018 SSL PIA winner), as well as its NU4RD—which won LightFair’s Most Innovative Product of the Year 2018—are Bluetooth-enabled to allow simple connectivity, commissioning and compatibility with other manufacturers for ease of specification, installation and utility. Derks says they do use DLC and Energy Star for energy efficiency certifications, but it’s not enough.

“They already have guidelines for controls, but they’re not related to setting standards. DOE is investigating this, and PNNL has published an interoperability report that provides some interesting perspective, but as a fixture manufacturer,

That’s not a surprising answer, given “Integrated Innovation” is the tag line of the company.

That credo, in fact, is a big driver in its culture,

nies. “It’s ingrained in our products, service and projects. We partner with companies like Xicato, Silvair and CASAMBI, who are on the cutting edge, and leaders in their space in intelligence, human centric lighting and color quality.”

“LOVE IT OR HATE IT, WE ARE CONNECTED IN ONE WAY OR ANOTHER, AND BLUETOOTH IS A PROTOCOL THAT SIMPLIFIES USE AND COMMISSIONING WHILE ADDING ROBUST, SCALABLE OPTIONS FOR OCCUPANTS.”

Xicato, he adds, has been a true solution provider, bringing a “Silicon Valley-esque” approach that aligns with LEDRA’s product development and roadmap. “We have spent millions on new products, integration and tooling over the past few years; our vendor partners don’t hold back either on R&D, and cooperate with us on our near- and long-term goals. As these technologies mature, it is critical that such tech providers provide A+ support to us, specifiers and the field.”

Furthermore, Xicato GalaXi and CASAMBI, among others, he says, have international teams of troubleshooters and commissioning support for any size installation. CASAMBI, he explains, is comprised of the former NOKIA management and the tech team who were part of the development of Bluetooth as we know it. “The GUI looks and feels like a NOKIA product which is clean, easy, user friendly and simple to commission.

What would have taken one to two commissioning days with legacy systems will literally take 30 to 60 minutes,” says Derks, adding up to 127 of their downlights can be installed per network switch on CASAMBI. “It’s great for small to medium projects, where GalaXi and other Mesh protocols, like Silvair, are robust for large commercial buildings, or huge galleries with no limits and complete interoperability compatibility with other mesh systems.

ARENA LIGHTING: UNITED CENTER, CHICAGO

Sporty Solution Chicago’s United Center—home to the city’s basketball and hockey teams—is doing more with less, thanks to a recent lighting and controls upgrade. The project replaced a legacy system with high-output Ephesus Arena Pro, along with a wired DMX control system. The new design uses fewer fixtures and is cutting related energy use by up to 75%, while also creating more uniform lighting for HDTV broadcasts. It also offers full dimming and advanced color-tuning capabilities for more dramatic displays for fans in the stands and at home on their sofas.•

HOSPITALITY: ZUBARAN, ATHENS, GREECE

Linking Old and New with Light Proving that a modern take on minimalism can mix quite easily with even the oldest architectural principles, the design of a new Mediterranean restaurant in Athens features a lighting design that emphasizes the ripples in its concrete walls and softens its industrial lines. The restaurant was designed by architects Maria Kokkinou and Andreas Kourkoulas, with lighting design by Okapi Light and L4A. The designers incorporated a range of lighting products from Soraa, including its Snap System, MR-16s and PAR 20 lamps, which were used in a unique ceiling installation and in the pendants suspended over the bar and dining tables. According to Okapi’s Mariza Galani, her favorite part of the design is the wall washing of the rough surfaces because, she says, it gave the space an urban touch by emphasizing the hard surfaces of the city at night.•

est growing design moments and marked Panasonic’s renewed commitment to developing products that enhance the experiences of everyday life. Panasonic showcased “Kasa,” one of the initiatives from its new design studio in Kyoto. An experiential exploration into the future relationship between people and objects, Kasa, specifically, is a set of delicate, light-filled stones which react to the behavior of the user; the objects descend into darkness if approached or handled aggressively. Through reinforcing positive actions, and discouraging negative ones, Panasonic hopes to promote a transition toward a new relationship between people and objects, whereby the latter are treasured and handled with care, and the former are inspired with feelings of calm and happiness. Takehiro Ikeda, creative director of Panasonic Design, and director of Panasonic FLUX, noted the theme, “Emotional States” is a natural for the biennale.

“The design of everything around us— our homes, environments, the clothes we wear and the products we surround ourselves with—all have immense power to influence our state of mind.

As new technology becomes ever more embedded into our everyday lives, there is no better time to explore the impact design can have on the very human language of emotions that we all intuitively understand and respond to.”•

THE STATE OF SOLID-STATE:

Winners and Losers in the Great Solid-State Revolution While it was once argued that solid-state technology was nothing more than an evolution—just another light source—it is now clear that something far more revolutionary is afoot. What has been, can be—and will be—done with SSL technology, cements this observation. But at the top of the “winners” list has to be the entire population of the planet earth.

of the theoretical 350 lm/W maximum for a high color rendering white light source. This doubling of efficiency difference (narrow chromatic emittance aligned with human visual response + high conversion efficiency) is why solid-state light sources can replace conventional sources with energy savings of 70%-90% for every usable lumen generated.

If one were to add to this SSL’s innate ability to create shaped light sources to suit a photometric design intent; its intense small source Photos: Courtesy, Sylvania

function in optical system development; and its ability to deliver service lifetimes that exceed conventional lamp sources, reducing maintenance costs, SSL clearly outshines its predecessors. But there’s more: SSL’s innate compatibility with electronics, which opens doors to dimming, effects, communications and controls integration that conventional glass bulb technologies are simply incapable of supporting. In the age of micro-processors, the glass lamp is equivalent to the vacuum tube.

NOT EDISON’S BULB While LED products sometimes maintain a familiar form, or even offer nostalgic effects, in this time of transition, the difference between conventional and solid-state is so significant, that the only thing common between them is that they both produce visible light that can be used to support or replace natural light in occupied space.

While it was once argued that solid-state technology was nothing more than an evolution—just another light source—it is now clear that something far more revolutionary is afoot.

THE ERA OF A NEW EXPRESSIVE MEDIUM In less than two decades, the symbiosis of artificial illumination and artistic visualization has become an influential applied and fine art form. The best examples combine painterly talent with technological virtuosity. The following projects represent six trends where LED lighting makes each exterior totally appropriate for its surroundings while communicating its own statement:  Structural and landscape enhancement: Conversation

Conversation Plinth Location: Columbus, Ind. The modest municipality gained international architectural fame in the middle of the last century, when Irwin Miller, chairman of the Cummins Engine Company, headquartered in Columbus, became instrumental in changing the-then decaying city 40 miles south of Indianapolis, into a showcase for buildings designed by architects the like of Eliel and Eero Saarinen, I.M. Pei, Skidmore, Owings & Merrill; Kevin Roche, and Cesar Pelli.

In the summer of 2017, on the plaza in front of the Pei’s Cleo Rogers Memorial Library, and the adjoining Henry Moore sculpture Large Arch, was added the threetier wood “Conversation Plinth.”

Its design, by the Boston-based architectural firm IKD, takes its form from the conversation pit in the living room in the Miller House, as well as the plinths that

elevate the important landmarks surrounding the site. Each circular plinth or pedestal is 74-ft. long, 43-ft. wide, and 15-ft. high.

IKD also designed the lighting that illuminates each level, utilizing LED NonFlex Vivid Basic to achieve the structure’s dramatic evening appearance.

IKD was awarded a $250,000, two-year United States Forest Service Wood Innovations Grant to fund the development of Hardwood Cross Laminated Timber to be used for the project—the first hardwood CLT project in the U.S. CLT, combining multiple species of low-grade Indiana hardwood, has the potential as an urban building material that is a fireproof, lightweight alternative to steel and concrete. SmartLam was the manufacturer.

If oil paints and watercolors had been invented simultaneously, artists instinctively would know that they could make these mediums tell a visual story by their own creativity. It occurred not by decree, but by the discovery over generations of how to personalize these mediums.

The remarkable introduction of the LED as a mode of applied and fine art wasn’t what its inventors originally had in mind. No longer do artists mix their own raw materials to produce oil paints or pigments for watercolors. Similarly, architects, interiors specialists and lighting designers who are painting with light, add a recognition factor to projects not possible before 2000. Color for illumination and the ability to create shapes with an illuminated source, neon, was first introduced by Georges Claude at the Paris Exhibition of 1910. Neon virtually owned the signage market throughout the rest of the 20th century. With the advent of LEDs, without the heat generation, breakage and hand-bending that characterizes neon, the market is shifting this way.

system drives the full façade with native HD-video output directly to fixtures. For the Replicants linear accent fixtures, a Cree high-performance 3-in-1 RGB SMD supplies 625 lm/m.

The Replicant was redesigned to provide a modular product with length variations every 4mm (5/32-in.). “This flexibility allowed every foot of lighting to be pre-installed at the façade contractor’s factory before being lifted into place,” says Joshua Van Blankenship, SV vice president.

The courtyard display utilizes an ultra-thin transparent interior blade system and the same Cree LED lamp capable of 8500 nits maximum power. For the crown sign, SV developed an exterior FX-L module crown sign, with Cree’s RGB DIP lamp, for 17,500 nits capability.

Redefining the LA skyline, the 73-story, 890-room hotel traces its concept to Daniel Burnham’s classic quote: “Make big plans; aim high in hope.” Architects AC Martin took heed of this advice, designing the top of the building with exterior illumination shaped like a swooping beacon. Media/ lighting consultants, StandardVision (SV), were brought in to integrate three display systems that establish the building’s illuminated exterior presence.

The high-resolution crown and courtyard displays are set behind glass and framed by the primary lighting. The curtainwall spire consists of more than 13,000 linear ft. of modular lighting in more than 220 distinct fixture length variations.

Brussels, Belgium last year joined other major metropolitan centers worldwide to sponsor a city-wide light festival. Bright Brussels, Festival of Lights for 2018 was held February 22 to 25. From over 100 submittals, 11 light art works were selected to be staged at locations around the city and along the Senne river. Over 120,00 visitors were attracted to view the various events, which ultimately could be described as interactive LED geometry in the form of free-standing sculptures that combined sound and light.

A perfect example is “160,” an interactive sound and light installation created by Lyon, France-based Trafik. It is a three-dimensional experience in perspective and distance.

Measuring 197-ft. long, 13-ft. wide, and 10-ft. wide, 20 square frames of eight light tubes each, for a total of 160 tubes that together produce a painterly contemporary vision when illuminated. Each PMMA tube has a diameter of 1.97 in., with an RGB SMD 5050 24V strip. Visitors are encouraged to experiment with changing

the color and perspective from a mounted control panel in front of the DMX-controlled installation.

D While a group of neon artists in color’s early days were responsible for an admirable body of outstanding site-specific neon sculptures, today many more artists, architects, lighting designers, landscape architects and multi-media specialists have been able to come onto the scene with arrangements of LEDs that range from defining a building to fixture groupings at ground level. Light as an artistic medium is interpreted for both exterior and interior spaces. City light festivals turn whole urban areas into a celebratory outdoor gallery. Amsterdam, which held its first light festival 12 years ago, is one of the largest. Other cities around the world that host a light festival include Brussels, Turin, Prague, Berlin, Lyon, Sydney, Frankfurt, Helsinki, York, Toronto, Montreal, and most recently, Baltimore.•

To give a distinctive new image to the exterior, architects MKDA designed double-height vertical white acrylic elements. Their softly rippling profile sculpturally interprets the waves of nearby Long Island Sound.

Situated on either side of the main entrance to the 10-story building are thirty-four, 20-ft. tall steel fins with integrated lighting, creating a crisp white visual anchor for the structure. In the evening, they produce a sinuous wave of light. The theme of sleek white cap foam is carried indoor to the lobby. Here, 60 of the wave elements are ceiling-mounted and fitted with LED edge lights, clearly seen through the glazed entry.

1810SSLTAF02.indd 26

Eventscape was selected to provide the wave elements. Mock-ups determined the final optimum finish for the acrylic and to verify LED light placement. Clear 1-in. thick acrylic was sanded on the sides, and edges were polished for a soft, frosted finish. When in place, they shield the building’s parking structure. Ten different wave patterns are repeated across the panels. Because the integrated lighting replaces standard street lights, the designers chose bright high-output dimmable LEDs with a warm color. Built with a structural HSS spine, baseplate and 3/16-in. skins, each wave weighed a total of 1800 lbs. All steel was galvanized, sandblasted, then primed and powder-coated for a long-lasting finish.

Eads Bridge

Location: St. Louis, Mo. Lighting: Randy Burkett Lighting Design Considered one of the engineering marvels of the post-Civil War era, the Eads Bridge is a 6,442-ft.-long combined road and railway bridge over the Mississippi River, connecting St. Louis, Mo. and East St. Louis, Ill. Completed in 1874 at a cost of $10 million, it was dedicated

by President Ulysses S. Grant on July 4 of that year. Named for the pioneering designer and builder, James B. Eads, it claims numerous first and early uses: a long bridge across the Mississippi; steel as the structural material for the ribbed steel arch section over the river; cantilever support methods; utilization of pneumatic caissons; and carrying railroad tracks.

Located close to the iconic Gateway Arch, the Eads Bridge is part of the St. Louis riverfront encompassing the recently completed $250 million Gateway Arch Park Foundation’s Arch site renewal, a project undertaken to better connect the area with the city’s downtown and the Mississippi River. Illumination of the bridge’s imposing stone-supported roadway approach to the bridge, designated a National Historic Landmark, is a major feature of the lighting program, helping to create a significant contribution to the city’s activities for residents and visitors. It serves as a backdrop to a newly created park expansion and natural amphitheater.

Lighting designer Randy Burkett led his team in selecting dimmable LED linear warm white color fixtures and their placement along the 800 ft. of wall, ranging from 10 ft. to 30-ft. high. “We treated it as an historic façade,” says Burkett, “placing the fixtures close to the abutment and grazing the surface.” Each fixture was aimed and dimmed independently from the others. “There are no deep shadows; just a gentile continuous glow of light along the textured surface,” he indicates.

Burkett also led his firm’s custom design of the pole fixtures along the 900-ft. long pedestrian walkway. Research into its Arch grounds original design led to the discovery of a drawing in the National Park Archives that is credited to the office of Eero Saarinen, the Arch’s architect. Inspiration from this sketch led to the design of a new 16-ft. high pole, topped with an innovative bracket-supported LED luminaire.

TOPICS AT THE FRONT

City of Lincoln Parking Garage “Gallery Alley” Location: Lincoln, Neb. Lighting: Patrick B. Quigley & Assocs.

Almost as soon as a large neighboring garage was completed to handle the crowds attending Univ. of Nebraska game days and visitors to the adjacent entertainment destinations, city officials agreed that something had to be done with the alley.

For years, the 125-year-old alley had been an impromptu staging area for art projects encouraged by the tenants of the adjacent Burkholder building, an artists’ loft and studio complex. When they observed that visitors gravitated to the alley as a short-cut rather than using the newly landscaped promenade from the garage to the university’s sports venues, they approved financing for the implementation of a badly needed new image.

Patrick B. Quigley & Assocs., Torrance, Calif., was retained as the project’s lighting designer.

“Our role morphed from making the alley safe and illuminating other’s art pieces, into one of contributing lighting that could turn the alley itself into an art element to be experienced at night,” says Quigley, the firm’s design principal. He chose as

his subject matter the alley’s working-class history and its “found art” infrastructure. “Its environment was the result of years of spontaneously mixing live and abandoned electrical wire, meters, conduits and transformer cans,” he says. The 275-ft. long alley is 18-ft. wide.

“We interpreted this cacophony of wire as a strangely beautiful thing, and devised ‘The Wire Symphony’ as an artful addition to the chaos, creating a ‘Gallery Alley’,” Quigley indicates.

The “Symphony,” takes its cue from the original random wiring system by mimicking its look, as well as reusing traditional electrical infrastructure such as risers, ‘weather heads’ and catenaries, while safely escorting pedestrians along to The Haymarket area.

The linear LED system zigzags the entire length of the alley and serves as its primary ambient light source. A bank of vintage electrical meters is front-lit by cross-aimed cool and warm washes of color, back-lit by a ladder of RGB/LED wall grazers. The array comes to life every 15 minutes.

Lighting the Queen’s Jubilee Gallery Westminster Abbey, London Architect: MUMA Engineering: Max Fordham Lighting Design: DHA Designs, Peter Fordham Photos: Courtesy of Xicato Text: SSL Staff The Challenge: Westminster Abbey is a museum, burial place, performance venue, national monument, tourist attraction, and most importantly, a working church. In creating a new museum in its upper level to house artifacts, a new lighting scheme was required that would not damage, nor take away from the historic objects or upset the historic architecture of the spaces.

The Solution: DHA Designs, in concert with daylight consultant Max Fordham, devised a fairly standard track and spot solution. However, what really made the project notable was the incorporation of a wireless Bluetooth control system that truly complemented daylighting efforts.

AWARD-WINNING CAFE BRINGS FEEL OF DAYLIGHT TO THE UNDERGROUND HSBC CAFETERIA Düsseldorf, Germany

As part of a modernization project, a staff restaurant and associated kitchen from the 1970s were to be architecturally renovated. An essential part of the design task was to introduce daylight by constructing a new light well, creating a welcoming, light-flooded, communicative environment for company employees and kitchen staff.

The lighting design team, Licht Kunst Licht, quickly learned that for structural reasons, only a confined shaft geometry with small windows could be realized. The comprehensive studies demonstrated that the daylight intake from such a light well would be minimal, with few positive effects of natural light and unnoticeable views to the exterior. This approach was rejected; instead, designers began work on an electric lighting-based, human-centric illumination that would support occupants’ circadian rhythms.

The team reviewed the district government’s requirements regarding daylight entry, and worked in close collaboration with the client, the architect, an occupational physician consultant, and an expert on occupational health and safety, to meet and exceed these requirements where possible. This collaboration ultimately determined the specific wavelengths and scene programming of the luminous wall design, simulating daylight’s annual variations, dynamics, light color, light direction and light intensity.

A floor-to-ceiling panorama window wall, more than 20-m long, shows a folded image of the river Rhine by a local artist. When illuminated, the wall compensates for the lack of daylight and emulates a relationship to the outdoors.

ABOVE: Behind the glazing, linear RGBW LED luminaires are concealed in the floor to simulate the natural light in the early morning and late evening hours. Linear LED luminaires concealed in the ceiling, with a color temperature spectrum between 2700K and 6000K, simulate daylight during mid-day hours. The intensity and color of these fixtures are automatically adapted to the time of day by means of an intelligent control system.

THE CHALLENGE: Illuminate a dark, artificially illuminated basement area housing a kitchen the cafeteria.

Initially a daylight “well” was to be constructed to bring natural light below ground. However, in working out structural details, it was realized not enough light would be shed to make the impact desired.

THE SOLUTION: Working with the architect and building owners, Licht Kunst Licht AG, devised a color-tunable illumination scheme that would artificially mimic the feel and color temperature of daylight by taking advantage of LEDs discreet ability to be hidden within a central art piece that would become a wall of luminosity.

High-Style Profile A 3-D light guide creates an eye-catching profile for a-light’s Aerial suspended linear luminaire—and it also is engineered to provide direct/indirect light distribution, with 45% uplight and 55% downlight.

The fixture can be specified in lengths from 2-ft. to 8-ft., which can be joined to create continuous runs.  Visit www.alights.com or Circle 298.

Human-forward design is mostly academic without light sources engineered to serve the desired requirements. There is a great deal more to be understood here.

1 Modular Film and Video Lighting The Anthem One lighting system features interchangeable “light cards” with varying light fields that can be easily swapped in and out of 5.5-in.cubed fixtures. With consistent edge-to-edge color and 0-100% dimming, the portable units allow complete customization of lighting effects.  Visit www.anthemone.com or Circle 297.

NEXT ISSUE: Heading underground—be it for the subway or any other subterranean sojourn—used to be a downer, but no more, as projects such as Seattle’s University of Washington Sound Transit station by LMN Architects, as well as subway projects in Holland and elsewhere, are making taking the subway an uplifting visual experience. Elsewhere, we will take a look at Steven Holl/BNIM’s Lewis Center at Princeton.

CORRECTION: In the August issue, on page 44, OSRAM’s Digital Systems group won a Product Innovation Awards for the OPTOTRONIC Programmable LED Driver with DEXAL Technology. We erroneously listed it as OSRAM Opto Semiconductors.
