RECONSIDERING INFRASTRUCTURE NOT TO HINDER, BUT HELP LIVES Brooklyn-based design studio, Urban Conga, was recently selected as a winner of Architizer’s A+Firm Awards. Its work highlights the impact play can have on the health, identity, social and economic values within the future development of cities and communities. “Oscillation,” shown here, is an interactive installation that focuses on using sight, sound and movement to spark spontaneous social interaction and conversation within a once underutilized space. The five-piece artwork acts somewhat like a giant theremin, where, as one walks toward it, it plays different sounds and pitches depending on one’s distance to it. The colors reflect and refract light differently based on people’s angle and position to the work—an open-ended invitation to play, dance, jam out and come together as a community in public space.•

ABOVE: The interactive installation was designed as modular pieces so the work can travel and activate new and unique underutilized spaces around the world.

In the Image of a City Video game studio developer Eidos-Montréal evolved in just over a decade from two employees to nearly 500 associates. Expanded working areas were needed to keep up with staff growth for the firm that created Tomb Raider and Deus Ex games. A two-level office space was leased in the heart of Montréal and La Shed Architecture was retained to unify the space into one coherent whole. La Shed developed its program in the image of a community. Eidos-Montréal management wanted a warm, human-scale environment where its designers, creatives and artists would feel at home. The architects designed the layout of the new space with a village in mind. Creative rooms, meeting rooms and management offices create paths that converge toward the forum, the heart of the studio, open on two levels that allows meetings as well as gatherings. The architectural elements and the custom furniture contribute to this social life of the agora, whether around tables designed to assemble or on the staircase that connects the two floors that also serves as an amphitheater during presentations. The urban geometry of this village is based on human interaction with city streets, intersections and squares. Desks are arranged to provide winding circulation areas. Pods are working pavilions for informal and creative meetings, creating subspaces. Inspired by the triangular shape of the company logo, the centerpiece of the project is the ceiling above the entire studio, functioning as a frame of thousands of triangles. It is comprised of acoustic foams, light fixtures, ventilation grids and the sprinkler system. To balance the angular side of the triangle and introduce softness, the architects accentuated the rounded profiles of furnishings supplied by local firms, De Gaspé, Kastella and Margoglia. © Maxime Brouillet

places and triangles left empty at the perimeter create contrast and texture on the ceiling. Triangulated lights overlook the traffic areas and draw a signage path as they energize the space.

Transparent Solution Since its grand opening in 1971, the Grand Theatre de Quebec has been a prized icon. The build-


ing is admired for its brutalist architecture, by Victor Prus, which is entwined with an integrated artwork—a concrete mural by sculptor Jordi Bonet that covers close to 60% of the interior. By the turn of the century, moisture had caused the steel anchors of its concrete panels to disintegrate. The latter could not be simply removed and replaced. An innovative solution was needed to protect the building’s heritage elements. The solution? Enclose the entire structure in glass, down to a bespoke silicone joint base. Lemay/Atelier 21 created a delicate steel structure on which the new glass rests—the result of intense teamwork among architects, engineers, construction specialists and manufacturers. With the glass envelope, illumination became a major component. Handling that end of the project was architect Guy Simard, who had working on a dynamic lighting concept for 15 years. With LED, his vision could now be fulfilled. To bring his vision to life, Simard selected Lumenbeam Large Color Changing and Lumenbeam Large luminaires in 3000K. Placed in tandem at the top of each vertical recess, the luminaires (one white and one color changing) light down to street level, providing the option for both classic white light and more festive color illumination. “We wanted people to know, just by looking at the building, what was going on inside. So if it was lit in blue, for example, they would know it was the symphony orchestra that night; if it was red, a rock concert—we wanted to establish a pattern, which would tighten the bond between the theater and the city,” Simard said. To complement the color-changing element, he positioned two 4-ft. Lumenfacade luminaires and one Lumenbeam Large in 3000K at the bottom of each concrete panel between the recesses. These are aimed back up toward the cornice, grazing the concrete and bringing out its character, resulting in a dynamic design that has © Stéphane Groleau

Art Deco Shines on Renewed Waterfront Located on an island within the San Francisco Bay, Naval Air Station Alameda was decommissioned in 1997 and since that time had remained relatively untouched. The site is now being transformed into the Seaplane Lagoon Ferry Terminal, public parks and housing. Architectural lighting design firm HLB Lighting Design was hired to create the lighting scheme for Alameda Point, including the ferry terminal, adjacent parking, public pathways, parks and streetscapes. The design team sought a new lighting standard for the area for several reasons. “Alameda’s existing street lighting standard was a traditional ‘acorn’ style,” said Andrew Moore, senior associate at HLB Lighting Design and lead designer for Alameda Point. “The design team didn’t feel that style luminaire would harmonize with the character of the architecture that was to be built on-site and would have appeared jarring in that context.” Equally important, the acorn fixture did not provide full cut-off, which would have had environmental ramifications. HLB selected Luminis’ Eclipse EC801 luminaire, which is mounted on Luminis’ PTA round tapered aluminum pole. There are approximately 30 fixtures at Seaplane Lagoon and its immediate vicinity. Double-headed luminaires line the waterfront promenade, illuminating bike paths, pedestrian pathways and a parking area adjacent to the dock. Moore chose a Type III distribution for all fixtures at Alameda Point, because the EC801 also lines roadways and adjacent walkways and sideABOVE: Luminis collaborated with HLB to provide some additional modifications to the luminaires to anticipate the city’s future needs. Light levels are adjustable via a step dimming switch, giving public works the versatility to make local adjustments as required. As well, the luminaire has been adapted for the future provision of a seven-pin photocell, which the city can add at a later date if and when it moves toward a smart city system.

walks. As a result, it illuminates the full width of the streetscape. “I’ve had the opportunity to visit the site several times, both day and night,” Moore said. “The Eclipse luminaires and accompanying poles are a very attractive complement to adjacent buildings. The quality of the illumination they provide is comfortable and inviting, and the streetscapes

Walterdale Bridge

Edmonton, Alberta, Canada

Painting an Elegant Portrait Edmonton’s Walterdale Bridge seems to dance across the North Saskatchewan River. Its main sweeping arch can be perceived as a ballerina at the peak of her Grand Jeté movement—both feet off the ground. At 763 ft. in length, the bridge, which connects the north and south sides of Edmonton, has both ends solidly anchored with massive thrust blocks. Seen in profile, the elegant structural form blends seamlessly into its city and river valley environments. The canted arches of the througharch structure are illuminated in classic white or with color-changing lights. Walterdale Bridge is a gracious, single span, twin through-arch steel structure. It carries three lanes of northbound vehicle traffic, a sidewalk to the west of the roadway and a separated footbridge for pedestrians and cyclists to the east. Another lane can be added in the future. The current population for Edmonton, capital of the Alberta Province, is 972,000, having added 72,000 to the residency rolls since 2016. DIALOG, a multi-disciplinary design firm with offices in Edmonton and other cities, was responsible for the architecture, structural engineering, landscape and electrical design.

W Hotel Osaka, Japan Architect: Nikken Sekkei; Tadao Ando for the façade Lighting Design: Lighting Planners Assocs. Interior Design: Concrete Photos: Courtesy, Marriott International Text: Vilma Barr The Challenge: Create hotel interiors and vignettes that match the vibrancy and excitement of Osaka’s streetscapes and the electric nightlife of the Dotonbori District, just around the corner. A secondary challenge was to counter the hotel’s simple, black monolithic façade with an interior that reflects the facets of the city. The Solution: The W Osaka blends Japan’s celebrated cultural heritage with bold contemporary designs in a rarified milieu of playful chic and boundless luxury, often expressed with light. Work hard, and play even harder, while making your mark and owning the moment, was the theme. The spaces deliver both super social and mouth-watering dining experiences.

Challenge: Upgrade the control system for Niagara Falls. Influence: Often referred to as a Wonder of the World, Niagara Falls is actually a collection of three individual waterfalls on both sides of the border. For decades, using technologies, from carbon-arc search lamps to Zenon, the falls have been illuminated; three years ago, the system was upgraded to LED. That said, technology’s continuing advance left the fall’s managers with a desire to implement greater flexibility for both developing new design concepts, as well as remotely managing the control system in the cloud. Solution: Pharos Architectural Controls was appointed to deliver a new system for lights,

Challenge: When Steinway & Sons, manufacturer of pianos since 1853, established its first Asia Pacific flagship store in Beijing, the company sought to create a music hall to combines its classic heritage and innovative music technology. Influence: Doubling as a retail store and a showroom of Steinway and family pianos, Steinway Hall Beijing brings the company’s most important innovative products and artistic movements to its music lovers. Furthermore, the hall incorporates the Horowitz Recital Hall on the second floor, which can accommodate more than 100 spectators, enabling concert hosting and master classes given by artists, musicians and educators. The basement boasts piano halls with professional acoustics and a recording studio. It also provides world-class piano technical services by its technicians. Solution: Serving as striking centerpieces in Steinway Hall are several Corona pendants from SONNEMAN–A Way of Light. Available in multiple sizes, each pendant casts a warm ringed glow of LED illumination, providing both the presence and the absence of volume. They are available in a range of larger diameters. These circular profiles of light complement the pianos below, creating a sophisticated atmosphere for musicians and music enthusiasts. According to Steinway CEO Ron Losby, the company is looking forward to ushering in more of China’s music lovers going forward. “We firmly believe that Steinway Hall Beijing will become a musical gallery where we can bring our most important innovative products and artistic movements to its music lovers, and thus provide them with an extraordinary musical experience.”• 

Challenge: Create a dynamic color-tunable space where people could enjoy sophisticated lighting typically not employed in most homes. Influence: As the pandemic forced people indoors, homes quickly morphed into makeshift gyms, offices, classrooms, and so much more. Such was the case with a newly redesigned residence in the Hamptons, where the owners wished to ensure their utmost health and wellness benefits weren’t impacted by more time spent indoors and away from nature.

Challenge: Residents of Winter Park, Florida, need to see healthcare professionals, as well as exercise, swim, eat and socialize in an environment that promotes both safety and warmth. Influences: Wellness, fitness and medicine are all under one roof at Duda|Paine Architects’ Center for Health & Wellbeing. The firm wanted the lighting to work well with the chosen materials, and have input on how lighting would accentuate each space. Cline Bettridge Bernstein Lighting Design (CBB) was commissioned for the project. © Robert Benson

One of their desires centered around families of lighting that could easily be mixed and matched. Solution: CBB turned to Gotham, and EVO and Incito lines of recessed luminaires for general illumination and accent lighting in the atrium, reception area, fitness center, multi-purpose rooms, corridors and stairwells, and swimming pool. “With comparable aperture sizing between the lines and consistent reflector finishes, you can install an EVO downlight next to an Incito accent. And from below, they look the same, creating a very quiet ceiling,” said Francesca Bettridge. Added Sang Yup Lee, senior associate at CBB, the lines use the same LED modules, so the light output and colors are consistent. “This contributes to the elegance of the design and enables us to meet the aesthetic demands of the space.”
