Forecasted Savings if DOE Program Goals are Realized…

Residential Commercial Industrial Outdoor

To call the DOE bullish on LED is an understatement, especially as shown in the agency’s latest Solid-State Lighting R&D Plan, a report consolidating the Multi-Year Program Plan and the SSL Manufacturing R&D Roadmap. Though, as the report notes, LED-based lamps comprised just 5% of overall lamp sales in 2014, they see energy savings from LED/OLED lamps/luminaires totaling up to 261 terawatt-hours (TWh) per year by 2030. With LEDs currently making up less than 10% of global lighting installations, the authors see further R&D as essential in enabling the technology to reach its true potential. As adoption ABOVE: The projected savings in site electricity consumption of 395 TWh in 2030, would correspond to about 4.5 quads of primary source energy, which is nearly twice the projected electricity generation of wind power and 20x solar. power in 2030.

Night and Day Difference

Welcome To The Family Sternberg's


The Greater Cleveland Rapid Transit Authority has 50 million riders and serves 38 cities in the area. The Water Front Line, which serves the Browns stadium and other downtown venues, was due for renovation in 2013. Among the planned improvements was the lighting for all five stations on the line. The old fluorescent and metal halide lighting had been in place for 19 years, and was difficult to maintain. RTA turned to EYE Lighting and specifically its Aphos LED area fixtures and LEDioc replacement lamps. “EYE was involved from the start, and really helped us select the right solution for both the buildings and the platforms,” said Matt Marotta, RTA project manager. The retrofit, he noted, will save thousands annually now that lighting maintenance is virtually a non-issue. “The energy savings is a bonus,” says Marotta, but more so, riders are happy. “They are telling us they like the new environ-

According to Chris Huntley, Millstone’s VP, after a quality assurance review, the contractor had a few special manufacturing requests to streamline installation. “The EYE response and follow-through was extraordinary. They reviewed the product with our installers, made project-specific changes, and delivered on schedule.” The city will continue to upgrade and renovate stations on other RTA lines using the EYE luminaires, according to Marotta• 800.621.3376

Bringing History to Light Oscar-winning cinematographer Vittorio Storaro along with his daughter Francesca— herself an international architect and lighting designer—got the assignment of a lifetime with a project intended to relight Rome’s ancient Imperial Forums. The installation debuted just in time for the Eternal City’s April 21 birthday. A primary design challenge was developing the right mix of wall-wash and spotlight fixtures. Luminaires with neutral white


light illuminate the architectural elements peculiar to each forum, such as remnants of the large temples or the Column of Trajan. Warm white light is used as a contrast for all other objects and surfaces. A range of ERCO projectors, floodlights and wallwashers were selected, including the Lightscan and Focalflood façade luminaires, to bring the Storaros’ vision of writing with light to life.•

LEDs Getting Smarter As Lightfair attendees no doubt noticed, manufacturers are adding intelligent functionality to LED fixtures and lamps at a rapid clip—in fact, the latest LED Smart Lighting Report from lighting-products consultants Alumage Advisors documents a 100% increase in intelligent features in just the last year. Among the specific features the report identifies, the following are leading the pack:  77% of the products tracked are dimmable.  59% offer integrated motion sensors.  49% offer network/controls options. The Boston-based firm anticipates the commercial and industrial market for high-lumen (greater than 5,000 lm) products to increase to between $11 billion and $14 billion by 2020, in part because added of the value smart-lighting features add to LED offerings. As a result, smart lighting products

with all others, employ interchangeable service components, utilize a single commissioning standard, and share a single communication protocol. This open-source approach has succeeded in other tech-driven markets, like personal computers, while DMX512 and 0–10V dimming are mainstream controls foundations. In transportation, NTCIP 1213 offers a universal standard of communicating between lighting and electrical loads. Other capable semi-open standards, such as Dali, Zigbee, Enocean and Emerge have gained modest strength in a market flooded with manufacturer specific proprietary approaches. Driver manufacturers and OEM fixture makers cannot support enough options to suit every protocol, nor are all available to them. As long as the market remains fractured by a mix of aging simplistic standards, multiple semi-open lowpenetration standards, and numerous proprietary systems, growth in full scale integration will remain slow and painful.


California State, Dominguez Hills, and AT&T are a pair of customers who have adopted Enlighted’s wireless sensor-based control system. An interesting strategy being employed by the company is that they’re essentially leasing the equipment to end users with the notion of actual energy savings dictating system cost. More than 800 sensors are installed at CSUDH.

system components remain unaffected. On a small scale the Philips Hue, WeMo, Wink, Smart Things, Iris and Insteon systems are forms of this. Unfortunately, each of these are built around unique protocols, using proprietary hubs optimized for their own devices. Even those advertised as Zigbee compliant offer limited functionality with competitor Zigbee components. With every component at a different state of development, failure of a hub or network component can cause serious issues, as will updates to firmware, app, or software. On recovery, some devices will re-connect automatically, others will require manual re-connection, while still others will fail to reconnect at all—requiring updates of discrete components or outright replacement. This is a small problem in limited applications. When expanded to the scale of a large commer-

According to UCLA’s Kevin Borg, the ability to adjust the lighting to different situations is extremely important. The school has also saved 35% on their electrical load.

Editor’s Note: This is the second part of our “Business of Lighting” feature, focusing on the relationship of the owner and designer. An important part of the puzzle to making high-end SSL design projects work, is first getting the client to buy in to the importance of lighting in the first place. Light as an Image Strategy A customized lighting scheme is a vital part in presenting any highend LED product. This involves the creation a new public image for an existing consumer product. Further, it often involves changing how the packaging will influence its target market. A variation of this visual appeal technique was applied to the Casino de Montréal (left). The lighting program, artfully integrated with the architecture, now defines and communicates a new contemporary public personality. Housed in two former Expo ‘67 pavilions, the casino recently completed a $300-million renovation which included the construction of an all-new entrance and lobby. A striking night-time presence was key to attract visitors to the site. “We wanted to make the building sparkle like a diamond shining in the distance,” says Mehdi Laieb, a principal with Ombrages, the project’s lighting designers. Much further south in Columbia S.C., image also played a key factor in the decision-making process of Love Automotive.

replacement effort has reduced the dealership’s electricity energy consumption by almost 50%. But to Michael Love, the operation’s president, the lighting retrofit achieved a much greater objective. “These lights absolutely provide the level of illumination we were looking for to make our location bright and secure,” says Love, president of Love Automotive/RV. “And, as the guy paying the bills, I’m impressed with the tremendous energy savings and payback. My only regret is that we didn’t do it sooner.” REAL RESULTS

No “I” in Team Such a reaction is no surprise to Paul Gregory of New York-based Focus Lighting, who acknowledges

Prior to the LED installation, the monthly electric bill at the dealership was $14,270; since the upgrade, the monthly bill is averaging $7,000.

the innovation that LEDs have brought in the past decade is undeniable. “People want to be energy efficient; there’s not a major need to convince most clients of that,” notes Gregory. “The lamp producers have done a fine job in bringing the message of lower long-term savings afforded by LEDs to business decision-makers,” he believes. That being said, what is not addressed enough, in his opinion, is the interaction between clients,

Closing the Educational Gap Beyond communication, getting architects and owners to the point where good lighting design is appreciated is a matter of education. It also has to happen much earlier in the process. Take the experience of Philadelphia-based architect Thomas R. Nickel. Lighting has always been a creative pursuit of the designer, but it’s never been easy. When studying architecture at Renssalear Polytechnic Institute he petitioned the dean with a request to minor in lighting, and was turned down. “The focus was more on building design concepts, structure and materials,” he says. To get around this, he did participate in programs at RPI’s Lighting Research Center to further his personal dedication to the discipline. But Nickel feels the lack of support for lighting as part of architecture curriculums is indicative of a generation gap. “It’s up to architects now in their ‘30’s and ‘40’s to assume the rule of the master builder and change the knowledge gap when it comes to integrating lighting as a recognized building material,” Nickel says. In walking the talk, Nickel is making a significant effort to make DO THE HOMEWORK

The Number 6 Turin, Italy Client: Building Domus, Piero Boffa, Luca Boffa Interior Architecture and Lighting: Building Engineering, Turin Design Collaborator: Luca Petrone Courtyard Lighting Concept: Richi Ferrero Text: Vilma Barr Photos: Piero Ottaviano The Challenge: Once the home of royalty, the classic five-story palace constructed over three-and-ahalf centuries ago in the center of Turin suffered from so much neglect that it lost its use as a desirable residence. When new owners purchased the property, they could foresee the renovation of the palazzo as an outstanding representation of adaptive reuse, respectful of cultural heritage, but technologically innovative and still conveying a sense of beauty. The Solution: The historic property was brought into the city’s mainstream by becoming 36 new apartments. The once-private courtyard space was recreated to be enjoyed by visitors as well as residents. While staying within the city’s guidelines on the reuse of historical structures, the design team captured the singular atmosphere and spirit of the building by introducing lights and plants to the 17th century courtyard. Interior spaces for the apartments are defined by LEDs and glass partitions, with generous open spaces for personalization by the residents.

The Courtyard The main idea for this space was to make it come alive by installing art, custom lighting, plants and flowers, notes Andrea Serapioni of Building Engineering. “Inside, for the design of the 36 apartments, we created layouts that, in a sense, integrate lifestyle solutions that respect the building’s heritage and also minimize ecological impact,” Serpioni points out. The building includes a gym and a large spa on the top level, plus a rooftop garden.

THE TEAM INTRODUCED LEDS ON THE THE SUSPENDED SCULPTURAL TREE, THE PATTERNED FLOOR AND WITH THE BALCONY PLANTERS. Lighting and plants transform the four sides of the courtyard and the plaza floor into a verdant, illuminated work of environmental art. Two planes, horizontal and vertical, were created. “A long horizontal line of the balcony rails are decorated with planters holding flowering plants as well as climbing plants that are exposed along the walls of the building. Each hanging planter is equipped with an automatic watering device and illuminated by two mounted lanterns,” Serapioni explains. A control system regulates the lighting of the planters, the courtyard’s illuminated paving design, and the light-accented tree sculpture into a fairyland-like visual experience. All the connections and wiring were specially designed for the project to minimize maintenance. “The power consumed by

By harnessing solid-state lighting technology in the service of effective storytelling, Gabe Guilliams and Pei-Chun Yang of BuroHappold Engineering, successfully executed the lighting design for the Brown Institute for Media Innovation at Columbia University, including the Institute’s central volume and several adjacent office spaces. Their work has been recognized with an IESNYC Lumen Award of Citation for Strong Execution of Concept and an International Assn. of Lighting Designers (IALD) Award of Merit. The pair’s goal, in illuminating this unique academic experiment devoted to the co-evolution of technology and storytelling, was to provide a lighting system that would effortlessly transform to support the institute’s varied programmatic needs. Designed by LTL Architects, the institute is on the ground floor of Columbia’s historic School of Journalism building. It functions as a catalyst— or incubator—for new technological practices in journalism, and comprises faculty offices, meeting rooms and a large, open, work environment configured to maximize its spatial qualities, daylighting and the visual impact of an existing double-height volume. A main architectural element is a continuous internal façade split horizontally into a walnut-millwork base and a translucent scrim above that acts to adjust light, conceal technical systems, provide acoustical treatment, and act as a screen for large-scale projection. To embrace the interconnected concept of the space, the lighting designers created a network of ambient light for the main room. The fixtures

THE CHALLENGE: To design an appropriate eco-friendly lighting system to support the diversity of programmatic needs at The Brown Institute for Media Innovation at Columbia University, a unique academic experiment devoted to the coevolution of technology and storytelling. THE SOLUTION: BuroHappold designed the award-winning lighting that embraces both the students and teachers that use this space, promoting a more engaging experience than a traditional lectureroom scenario. The low-voltage LED fixtures used offer flexibility for a very varied roster of events that take place in this space, from lectures to concerts. PROJECT CREDITS:

Situated on the banks of the river Lech in Austria, Lech am Arlberg is a picture-postcard skiing location, surrounded by impressive mountain scenery. Like many of its kind, the small town lives on tourism, and thus has been preserved as a smallish village settlement and makes high demands on itself. For instance, Lech was distinguished with the title “most beautiful village in Europe.” Thanks to the new lighting concept developed by Dieter Bartenbach and implemented in close collaboration with Zumtobel, the town is now presented in perfect light. “The existing street lighting system with its obsolete technology was simply not up to contemporary requirements anymore,” says Karlheinz Egger from the Lech building authority. However, it took many meetings as well as a lot of persuasion to win over political decision-makers, administrators and the local hotel keepers to opt for a new lighting concept based on LED technology. Upon surveying the town, lighting designer Dieter Bartenbach found a “lighting mess” that “blurred” the townscape. Such a diffuse lighting situation is usually caused by conventional outdoor lighting mostly involving lamps with open light distribution. This is countered by the illumination of shop windows and advertising facilities through highly excessive light radiation, which makes the original townscape disappear completely. “The perception of space is overturned in that the attention of the viewer is drawn exclusively to the sources of glare,” Bartenbach explains. His corrective concept ensures that the night-

THE CHALLENGE: Preserve the beauty and historic nature of the Alpine ski town while modernizing the community’s street lighting. THE SOLUTION: The night-time appearance of the ski resort has been changed by a newly implemented LED lighting concept. In collaboration with Dieter Bartenbach, Zumtobel developed a custom solution which skilfully illuminates not only the townscape of Lech, but also the river of the same name. A specifically developed control system adjusts the lighting levels depending on the time of day or night, so that the lighting conditions will be perfect at all times. PROJECT CREDITS:
