ARCHITECTURAL SSL • Chronicling the Advancement of LEDs in the Built Environment
ENLIGHTENMENT. Lightfair, the industry's primary U.S. show, this past decade, has often overwhelmed its participants with a cacophony of choices that has obscured forward vision; a sense of clarity, however, is emerging as the LED market matures.
AT THE FRONT In the context of architectural ceiling expression, lighting becomes a significant element in creating a more memorable user experience.

Bringing Light to Life While some companies develop straightforward product and branding videos, Zumtobel has taken a more surreal approach. In collaboration with video artist Andreas Waldschütz, they’ve launch “image film,” available on Zumtobel Group’s YouTube channel. It highlights the products and creativity of the company’s creative showroom, the Light Forum in Dornbim, Austria, through the eyes of a silent character who is placed at the center of a fast-moving display of the latest lighting technology. The artist captures the essence of this place by personifying the Light Forum. In other words, he lets it speak. “The light forum appears very futuristic and, in my opinion, really represents the soul of Zumtobel,” said Waldschütz. The

FACADE ILLUMINATION: COLOR MATCHING
When Not Just Any Red Will Do A playful upgrade to the headquarters for iconic “Little Red Wagon” maker, Radio Flyer, features a colorful wall of light that’s strong enough to make an impact even during daylight hours. And, while the Dyna Drum Ho and Dyna Flood QA fixtures from Acclaim Lighting can produce a rainbow of colors, special attention was made to color-match the company’s signature hue. JR Lighting Design of Tinley Park, Ill., worked with lighting experts from Gensler Architects to develop the plan. “The most important part was that the batch of installed fixtures color match as much as possible because the façade system as a whole was one large surface that needed to be illuminated evenly and show no signs of color variation,” said Jason Ryberski, head of JR Lighting. Acclaim worked with JR Lighting Design to custom populate

Where 2008 went to great pains to present LED technology in its proper place in context to other surviving glass-based technologies, 2018 was far more focused. There were virtually no conventional products on offer, save a few HID examples, which—regardless of how good they were—just seemed out of place. The ubiquitous retrofit lamp, whether bulb, reflector or tubular, was simply not taking center stage as they have before—a refreshing change to those who find these products to be mundane stop-gaps to the true revolution. There were a few exceptions to this, with Soraa presenting its strongest case and most demonstrative display yet. Most significantly in this category, the message is no longer focused on the singularity of the lumens-per-watt mantra. The discussion is on quality of light, dimming range (low end control), dim-to-warm features, and loss of the annoying arrays of individual LEDs in dazzling singular optics. While retrofit lamps were a far smaller part of the show itself, those that were
EVOLVING FORMS Clearly visible on the show floor of this year’s Lightfair was the maturation and evolution of familiar forms, most notably the downlight. For example, Prescolite’s 2-in. aperture D2LED in application gives real meaning to a “quiet” ceiling. The manufacturer even exhibited a 1-in. offering.
present were more welcome than those of the recent past. What is most significant change, is the consolidation of products to a narrow range of forms. The days of rampant creativity in decorative and speculative designs has evolved into much more focused range of products within just a few basic types. The categories of down-light, cylinder, troffer (2 × 2 for the most part), cove light, low profile display (under shelf), linear architectural effects, and surface/track mounted accent lighting were the foundation of this year’s show. While this can be discouraging, if not predictable, there are numerous innovations within
Soraa is not only pushing the edges of LED color quality, but also form and even placement, as they hung their light engines from aircraft cable to great effect, challenging the notion downlights should only reside in the ceiling.

ABOVE IT ALL Not too long ago, the ceiling in a commercial interior was a bland, flat expanse overhead between the walls. Functional, yes, but not exciting nor artistic. It was a place to hang fluorescent fixtures in offices, suspend track lights in a retail store, or install a chandelier in an upscale dining establishment. In most mid-20th century annual corporate reports, there are photos like these to graphically give the document a sense of time and place. Innovative lighting emanating from overhead has come a long way in a relatively short time, as the projects selected for this international overview demonstrate. From an equipment standpoint, LEDs have made it happen, like paintbrushes on an infinite palette. Where do designers today draw from to create the ceilings where function and art collaborate to express and define space? Milan-based architect Marco Piva, who has designed significant new and

Ispak Flexible Packaging Company Offices Location: Istanbul, Turkey The goals of the new HQ for the industrial packaging products made by the Ispak Flexible Packaging Co. in Istanbul gives equal weight to a trio of priorities. For the 49,000-sq.-ft. building, Ispak management and architects Mimaristudio were in agreement that the building should embody an interior environment where employees feel comfortable; reflect the firm’s innovative and colorful image; and provide social meeting points responsive to the needs of both office employees and factory workers. During the planning phases, Mimaristudio considered the welcoming lobby for guests; showroom; conference areas; administrative offices and workspaces; R&D lab; production facilities, cafeteria; training rooms; and recreational facilities.

A background of two main colors in different tones and styles visually coordinate the various spaces throughout the facility. Many Mimaristudio assignments involve the creation of project-specific product designs. For Ispak, custom furniture and decorative and functional LED lighting are seamlessly integrated with the building’s architecture and interior geometry. Ayça Akkaya Kul created the lighting fixtures used in the assigned offices and in the segmented and linear ceiling pattern of the open offices. Dark Lighting collaborated with Mimaristudio on the technical planning and manufacturing of the fixtures.

D renovated hotels, homes, stores and more, typically creates his own lighting for his projects. He recently sponsored a gallery show of photographic enlargements of his firm’s work around the world, with an accompanying catalogue, “My Light Years.” In describing how he gets ideas to illuminate his projects, he says every project to be illuminated must sink it roots in culture. “Its references are drawn from the territory, from history, from the customs and traditions to which the structure grafts its own presence. Before I begin a lighting design project, I look for references in art—painting, sculpture, and theatre—and especially in paintings, from Renaissance to Baroque, from Pop Art to Kinetic Art,” says the designer. Such work also involves and includes: Assiduous research into the receptive structures The formal and functional spacial characteristics The elaboration of the materials in their environment The honing of technologies designed to enhance the
expressive and performance capabilities of the materials.
C Kusmi Tea Store Location: New York, New York London-based designer Christopher Jenner’s interior for the luxury tea brand Kusmi Paris in New York’s World Trade Center is at the other end of the spectrum from the typical dark-hued tea shop atmosphere. Instead, Jenner created an elegant and colorful interior that intermixes appealing product display, marble, glass mosaics, and curved details for the floor, ceiling, and walls. LED fixtures and lamps provide all illumination for the 720-sq.-ft. interior. “The brief from Kusmi management was to create a bespoke environment that would visually communicate the company’s heritage and distinctive image,” says Jenner. The company, launched 150 years ago in Saint Petersburg, moved to Paris in 1917 where it is now headquartered.

“To encourage shoppers unfamiliar with the brand to enter the shop, we created a focal point—a custom stainless steel, three-tier chandelier,” Jenner indicates. Its 30 interlaced, organic arms connect to a central shaft of multiple turned components that disappear into a multi-colored, stained-glass onion dome set within the ceiling, outlined with cove lighting. Attached to the side walls and back of the space are tiers of floating glass built-in shelves, joined by stainless steel connectors. A tasting station beneath the chandelier features four handmade stainless steel samovars, offering a selection of blended teas throughout the day. The new interior concept will be used in Kusmi Tea stores in the U.S. and international markets.

says Cheing, by utilizing raw materials, casual-style furniture, and lighting with daylight sensors and dimming features. “The variety of hanging lighting fixtures contributes to the residential or informal hospitality environment that was our goal,” says Cheing.

D Lighting, adds Piva, also informs the users of the space’s personality. The designers of the projects included in this issue’s collection have applied Piva’s reference points to their own projects. Carlos Serra exposed a 150-year old beamed ceiling for the Pelayo Trinquet in Valencia. The clear sculptural rod fixture in the Saks Fifth Avenue store in Toronto (p. 28), and the floating glass kites of the Nuée de Verre in the Montreal airport are illuminated by LEDs to carve out ceiling spaces that give artistic distinction to the near environment. Deft application of lighting technologies for overhead fixtures enhance the architecture for environments created for staff at companies where innovation and collaboration are stressed, like Ispak Flexible Packaging in Istanbul. Chandeliers still appear in upscale shops, such as Kusmi Tea in the World Trade Center, New York. Sleek and contemporary, the fixture is an appropriate addition to the bold layout and multi-level product displays. Innovation and inspiration played important roles in the seamless integration of the lighting and architecture for these projects. As applied to a distinctive ceiling expression, lighting becomes a significant element in a memorable user experience.•
Trinquet Pelayo Restaurant
Location: Valencia, Spain Lighting: Carlos Serra, Mercader de Indies Restaurant patrons at the Pelayo Trinquet in Valencia, Spain dine in the presence of an overhead sculptural representation of a pilota glove ready to snare a ball to power it back to opponents. Valencian pilota, dating back to the Greeks, is considered a national sport and draws crowds to events played in several European countries, Mexico and Argentina. Its U.S. version is known as jai alai. One of the most renowned trinquets (courts) of the pilota sport was established 150 years ago at the corner of Pelayo Street, next to Valencia’s main railway station. Interior specialist Carlos Serra of Valencia-based Mercader de Indies, a design firm and product resource, defined the restaurant’s long rectangular space that echoes the outlines of the pilota court with color and double level of visual details. Above the outsized signature glove and ball is the original beamed ceiling, recovered by Serra during studies for the space’s renovation.

Saks Fifth Ave.
Location: Toronto Lighting: HBC Store Planning At the main entrance to the 163,000-sq.-ft. Saks Fifth Avenue branch, located within the sprawling Toronto flagship of the Hudson’s Bay Co., is a massive sculptural LED fixture that visually establishes the store’s upscale merchandising approach. The chain was purchased in 2013 by HBC and now operates as a division of its international retail holdings. Measuring 27 ft. × 16 ft., the oval fixture that encircles a major structural column was fabricated and installed by Eventscape. Architect was BHDP, with fixture design by HBC Store Planning, Design & Construction.
The fixture consists of 600 glass rods of lengths varying from 18 in. to 36 in., each weighting between 2.5 and 5 lbs., suspended from a mirrorfinished laminated backplate. Lighting Nelson & Garrett Inc. was responsible for the internal LED lighting of each of the rods. At completion, the backplate was attached to a plywood subframe with hidden z-clips.

High on the list of objectives established by Aéroports de Montréal for the new international jetty at the Pierre Elliott Trudeau Airport was to make it visually memorable. The all-too-familiar faceless interior expanses endured by travelers had no place in innovative, design-savvy Montréal. The analysis by the design team led by the architects Lemay + CHA/Jodoin Lamarre Pratte was to create an illuminated overhead installation that would not divert the attention of the users with floormounted elements. Rather, their solution would be overhead, a combination of art, technology, and wayfinding. To implement their vision, they invited the lighting and scenographic design firm of Atomic3 to devise the work so that it would also intuitively interact with foot traffic below.
Michel Hardy, architect and senior partner at Lemay, and the Atomic3 creative principals drew inspiration from three sources: the stained glass windows of Montréal’s numerous churches; an airplane’s profile; and the movement of passengers from the jetty onto the aircraft, and in reverse when they deplane. The designers titled their work, “Nuée de Verre,” or “Veil of Glass.” Its realization is a series of suspended illuminated kiteshape triangular glass panels that change color and movement from signals generated by the activity of the passengers and airport personnel. Nuée de Verre is both fanciful and technologically sophisticated. Two versions of Lumenbeam 3500K Grande fixtures from Lumenpulse supply the lighting for the space: Very Narrow 6˚ spot, and Narrow 10˚ spot. Their customized digital control capabilities were integrated with video systems. Design of the interactive modules was by the consulting firm of 20K.

Content for Tower and Fins: Moment Factory Photos: Doublespace Photography Text: Vilma Barr The Challenge: The directors of the Centre had two choices to change the physical image of the nearly 50-yearold, Brutalist-style building that housed performance spaces and public areas. They could demolish the structure and start over. Or, they could undertake a top-to-bottom, front-to-back renovation and promotional repurposing to attract a broader market and give the country’s capital city a world-class entertainment venue. The Solution: The vote was for a thorough renovation to create interiorexterior relationships and become a new visual beacon on the Ottawa cityscape. Funding totaling approximately $226 million was provided by the Government of Canada in two nearly equal amounts—one for architectural and building systems upgrades, and the second for performance hall and support space upgradings. LED lighting was integrated with the major architectural elements, including the interior geometry of the ceiling of the new lobby.

DYNAMIC PLANES OF LIGHT CREATE ILLUMINATED CLOUDS OF COLOR IN TURIN LUCI D’ARTISTA INSTALLATION Turin, Italy
On the 35th-floor atop the Intesa Sanpaolo building in Turin, Italy, on the evening of November 20, 2017, the integrated LEDs were turned on to reveal a sweeping vision of a suspended array of 100 colorful banners. The event was staged for the opening of the city’s 20th Luci d’Artista celebration. For 80 days beginning in late November, the city becomes a contemporary art exhibit for approximately 25 illuminated works, installed in open-air settings and in dedicated interior environments. The celebration has become an attraction for the two million residents of Turin’s metropolitan region, and attracts international visitors to experience the visual magic seen throughout this northern Italian business and cultural center. Migliore + Servetto Architects was commissioned by the banking group Intesa Sanpaolo to create a work for Luci d’Artista with complete 360˚ visibility. The concept to fulfill their client’s request was developed by the partners of the Milan-based practice, Ico Migliore and Mara Servetto. They described the solution as “a luminous vortex, a wave of colors that are very sensitive to changes in the natural light that fills the open space.” Located 550 ft. above street level, it features the building’s bioclimatic greenhouse and the Piano35 restaurant and lounge bar. The architects say their creation is ‘a-cromactive,’ drawing inspiration from the alpha sign, which, the architects point out, is considered a symbol loaded with positive elements with a reference to the origin of everything. An innovative combination of printing, lighting and materials

LUCI D’ARTISTA INSTALLATION, Turin, Italy
THE CHALLENGE: To mark the opening of the city of Turin’s 2017 celebration of Luci d’Artista, the banking firm Intesa Sanpaolo wanted to sponsor a display on the top level of their building that could be seen from anywhere in the region. The structure, a graceful column designed by architect Renzo Piano, is crowned by a three-story-high, glassenclosed open space. Inside, there is extensive interior landscaping and a restaurant and lounge with views across the cityscape and snow-capped Alps beyond. THE SOLUTION: The architectural firm of Migliore+Servetto was retained to create a distinctive project that would communicate the bank’s progressive image. Their design combines lighting and materials technologies in a visually immersive work that transforms the designated interior environment. As part of its practice, the architects apply ‘lightmorphing,’ which they describe as “giving life to site-specific, dynamic installations that interact with the light, whether natural and artificial, and through this light are shaped, intermingled, and amplified.” For the Intesa Sanpaolo space, their ‘a-cromative’ work that floats overhead is realized by 100 colorful illuminated banners that move in response to indoor air currents.
ABOVE: Migliore and Servetto explain that their plan was based on “individual elements that collectively create a single form and entity, composed of densities rather than dissimilar shapes. In this way, the individual elements would create different scenarios, where transparency and lightness become action, movement and light.”
