Happy Circadian Hour: Our Biological Clocks and Lighting On 20 November, designing lighting global (dlg), in collaboration with Dr. Shelley James, will unveil Happy Circadian Hour in London. Dr. James will share her pioneering insights on circadian rhythms and lighting to 100 lighting designers in this CPD-approved discussion. Understanding our circadian rhythms, or biological clocks, is more than just knowing when we feel sleepy or awake. The evening’s agenda will delve deep into: • Current understanding of circadian rhythms and how light plays a pivotal role. • Recent discoveries, including the non-visual pathway in the visually challenged and the centers responsible for our circadian control. • Intricate connections and distinctions between visual and non-visual pathways. Dr. James will moderate a panel discussion with notable figures Ulysse Dormoy, Colin Ball, and Jesse Lilley. Dr. James commented, “Scientific understanding of how light affects the body clock is moving at warp speed. This session will be an opportunity for professionals to discover the ‘known knowns’ and the ‘known unknowns’ so that they can interpret standards and specifications with a critical eye.” While there is no complete agreement on circadian entrainment metrics, there is widespread consensus on the benefits of brighter days and darker nights. The current moment is opportune for lighting designers to incorporate circadian principles into their work. Lighting designers at the event will also explore spectra, intensity, distribution in the visual field, and how prior exposure affects light sensitivity in the evenings. The event is hosted by Atrium, LTD and sponsored by Lumenpulse and LMPG. Seating is limited to the first 100 lighting designers, and there is no cost to attend.

BENYA’S ART & SCIENCE

In my June 2023 column, I revisited my personal design theory of lighting by layers, which I believe is a good fundamental technique that can be taught and eventually becomes innate with experience. But, as I noted, my layers were unveiled in the late 1990s when major changes in lighting controls were underway, and more importantly, long before LED lighting was efficient enough and practical for general lighting. Lighting controls had advanced considerably since the first generation of what we now call lighting designers began to employ lighting controls as a design tool. Yet, compared to today, little was possible, and the user interface was limited. My, we have come a long way. For indoor architectural lighting purposes, it’s probably best to differentiate among the over-arching “controls strategies” that lighting controls might employ in a particular space or building. These strategies are not standardized – heck, this article caused me to come up with them, and others might not agree. But I think that these fit the majority of approaches to controls.

Energy Codes and Efficiency This strategy is a slave to energy efficiency codes and standards like California Title 24 and ANSI/ASHRAE/IES 90.1 that have specific requirements including automatic shut-off (motion or time based), dimming controls, and daylight harvesting. Manual controls and manual overrides are permitted in some cases. Compliance is mandatory for government projects and in states that have adopted it. But we can get carried away with automation. For example, in Title 24 proceedings, I argued against certain automatic switching in homes and hospitality environments that could cause safety or security problems and successfully limited the locations where Title 24 requires motion sensors.

Convenience, Hospitality and Identity Even in the most basic of lighting situations, providing manual control of lighting is fundamental. Giving choice to the user permits a light source or scene to be energized. This strategy employs manual control stations and is particularly important in residential and hospitality spaces where automatically switched lights would be a distraction and detract from the quality of the environment, day or night. For example, the lighting for a hotel lobby should be inviting and speak to the character of the property, even at 3 a.m., and hotel room switching should be left to the occupant.

Functional and Occupant-Selected Scenes Lighting scenes are an important part in the artistry and/or functionality of the lighting in many space types. Until energy codes mandated controls, scene controls were, from my experience, the primary reason to have more than dimmers and switches, as they enabled a lighting design intent to be realized with the push of a button. I still use this approach, except codes will now require an automatic “off” function, usually using a time function to ensure lights are turned off during periods when the facility is closed. I think the most difficult spaces to design are performance venues where both theatrical controls and architectural controls have to (hopefully) work in unison.

Wellness

As we learn more about the role of light in what we now know as “wellness,” there is an increasing demand for lighting that

designing lighting

BENYA’S ART & SCIENCE provides positive reinforcement to circadian systems. Wellness controls may be highly integrated with daylight and shading controls to ensure proper directionality, intensity, duration, timing and spectral control of light exposure to occupants of a space. As I see it, the broad concept of wellness can also be applied to lighting in indoor agriculture, animal husbandry and zoos, medical facilities, and other indoor environments, and it is not just limited to human work and living environments.

Common Sense When all else fails, electric lighting is an integral part of living for most people. As the efficiency of LEDs has increased, the waste of electrical energy has fallen dramatically. But energy should only be part of the reason for lighting controls of the right type and reason for the situation. That’s my job and yours. I have generally not included theaters and similar spaces where there is a clear link between management and lighting operations, but even that is changing with the house lighting control being tied to an automated projection system. My primary concern with automated environments is what happens when things go wrong. Having an effective and accessible override is essential in any public building for emergencies, and of course it should be designed to provide emergency lighting in power outages. In this capacity, the more manual, usually the better. Pre-set scenes date to the use of theatrical lighting systems and then, after dimmers and motion sensors, were among the first lighting controls to gain wide acceptance in every application from residential living rooms to hotel function spaces and board rooms. What I particularly appreciate about scene dimming is that is preserves my design intent for the layers of lighting in the room it controls. In some rooms, it is essential for creating the right ambience or mood, as in a restaurant; in others, the scenes are coordinated to accommodate video environments that can change to become paper-intensive work or meeting environments, or perhaps to support the action in a concert or nightclub facility. Gone are the days of projected video and its low luminance needing a dark room, but lighting controls are still a tool for changing the luminance balance of a meeting space for recording or dramatic effect. All of this is good, as it expands the role of the lighting designer to more closely resemble that of the lighting designer in the theater. You create scenes and moods that can change with occupancy, time of day, daylight, and other factors like media. So, as you might imagine, the latest innovations in lighting controls expand and, for many projects, spread, the same challenges.

the Potential of Networked Lighting Controls: Insights from the DLC Controls Summit 2023.” Today, David Shiller wrote in LightNOW, “Here Comes the Lighting-HVAC Integration Tsunami.” The idea is to employ the lighting control system to provide additional information to the HVAC system, and with the added connectivity, HVAC systems can operate more efficiently. This idea is not new. I call your attention to my February 2023 column, “What Could Possibly Go Wrong,” in which I describe a new-in-2015 energy management system for a school that could not turn the lights off – ever. The system itself had failed, and because it was so highly integrated with all building systems, became a massive liability because the manufacturer was bankrupt and gone. To prevent this, I tend to specify systems from reliable, established and yet progressive companies, so I can sleep at night… Personally, I am torn. The integration of lighting controls and HVAC controls has been a dream since the first programmable energy management systems of the 1970s, but the truth is, the electrical industry speaks a different dialect from the HVAC industry. David Shiller makes the point that LED “socket saturation” has reduced lighting power density in commercial buildings so much that sophisticated penny-pinching controls are hardly warranted. But extending their role to better manage HVAC systems is worth looking into – and perhaps, may serve as the foundation for completely integrated building controls including the management of solar energy systems, battery storage, vehicle charging, and other energy uses. I think the lighting industry, our government agencies, and our industry organizations have done a superb job of reducing the energy consumption and carbon footprint of lighting with LEDs and control systems that are robust and reliable, but the integration with other energy uses in a manageable building is still evolving. I hope David’s “tsunami” is a friendly one that resolves the many problems and challenges of lighting and HVAC living and working together in ever more efficient and pleasant buildings of all types. Finally, the layer system breaks down outdoors, and new issues and meanings are needed. I’ll save that for future thoughts on outdoor lighting. As one might guess from my years of service with the Board of the International Dark Sky Association, I will try to explain how a host of environmental concerns and protecting the night sky are on track to collide with increasingly capable outdoor lighting and special effects, and how design professionals might address the challenges. P

There is of course, one big movement gaining strength that involves lighting controls. In today’s market, there is an over-arching temptation to integrate building energy systems with lighting control systems. In an email blog I got the other day, our Editor, Randy Reid, presented his take on “Unlocking King, Ryan. Smart Home System. Canva. 15 Oct 2023 14

THE BUSINESS OF LIGHTING DESIGN™

Digitizing Lighting in the

Era of Decarbonization

By CAROL JONES DALI Alliance, NA Market Development Manager

THE BUSINESS OF LIGHTING DESIGN™

Webster defines an era as "a period identified by some prominent figure or characteristic feature," and "a stage in development." Reflecting on my years in lighting, it wasn't hard to identify distinct developmental stages. In some cases, we can be proud of our participation as an industry. We have been leaders in energy efficiency, lighting quality, and healthy buildings. Sustainability and circularity are an ongoing effort. On the other hand, our presence and leadership have been lacking in the net zero, resilience, and decarbonization movements. It begs the question—why? In this author’s humble opinion, it’s because these challenges in particular require digital, addressable and granular lighting controls features. There has been awareness, buzz, and a sliver of good examples—but if we are honest with ourselves, we can't say we've made major progress. North America is a 0-10V analog region. To be fair, there are legitimate reasons why we haven't transitioned to interoperable digital controls. There are profound barriers integral to sales channel dynamics, including financial disincentives, as well as educational gaps throughout the lighting ecosystem. I recently went to several conferences to learn about the relevance of digital lighting in the decarbonization era. My findings were consistent and troubling. At this year's CREtech in NYC, decarbonization was THE topic. Most attendees were real estate professionals, with a decent number of trade vendors, practitioners and domain experts represented. I spoke with many highlevel real estate executives and contractors from large global firms, including Brookfield Properties, Vornado Realty Trust, The Durst Organization, GSA, Tishman Speyer, JLL, Johnson Controls, Schneider Electric, and more. I couldn’t resist calculating the square footage of the real estate owners and operators that I spoke with: >5.6 billion square feet. The Greenbuild conference was similar, and upcoming conferences are also prioritizing the topic of decarbonization. The takeaway from my short interviews and conversations is: "We are done with lighting." The sentiment was echoed by an onstage reply to a

question from the audience, "What is the first thing we should do towards decarbonization—what is the low-hanging fruit?" Answer: "The first thing that comes to mind is lighting, but we have already converted to LEDs. There could be controls, but all the vendors talk about is what makes them different and better than the next guy, and we can't figure it out." Then he moved on to heat pumps and other technologies. These people are not ideologues. They are sophisticated real estate leaders. According to Schneider Electric, 90% of existing buildings will become a financial risk if they fail to decarbonize. Importantly, the ROI for medium-level decarbonization efforts is expected to be in the range of 8-15 years, which could make a significant difference in the viability of controls retrofits. In a conversation with Lance Davis, FAIA, LEED Fellow, GSA, Sustainability Architect and P100 Manager, he said, "GSA has the largest managed inventory in the country, totaling 366 million SF of owned and leased property. Most of our buildings are long-term assets, so we need to be concerned about what happens 5, 10, 30 years from now. If a driver or sensor is discontinued or a manufacturer goes under, will we be stuck without the data that we use for real-time operations?" Clearly, digital, interoperable technology is the best way for GSA to be good stewards of our government buildings. Real-time operation has taken on a new meaning now that commercialization of AI and machine learning for buildings is underway. Gary Chance, CEO of the award-winning and industry-leading company Prescriptive Data, creator of Nantum OS, offers an important sentiment: "Breaking down the silos of digital data within buildings is the cornerstone of operational decarbonization. Once data has been collected, cleaned, and properly stored, it can be applied to additional machine learning algorithms that help detect patterns and anomalies, creating economic opportunities for real estate owners. We don't work with lighting as often as we would like, but we see tremendous value in integrating lighting automation with other buildings systems.”

rather than competing with each other using an offering that is compromised in the eyes of the decisionmakers. Huge money is being invested into decarbonizing buildings, and as it stands, we will not get a meaningful slice of that pie.

It helps to clarify the priority criteria for customer success. Building owners and managers want a global open protocol that enables interoperability between sensors and drivers and delivers data in a standardized format to support APIs and integration with multiple controls and buildings systems. Michael Amato, a Systems Sales Specialist at Signify and formerly an integrator at FSG, says: "Digital solutions and system integration is the future, and end-users want interoperability and smooth operations for the long-term. Meeting their needs builds trust, expands markets, and allows our innovations to deliver their full value. Isn't it time for the lighting industry at large to make this a priority?" The global DALI Alliance delivers on these requirements. DALI-2 is now capable of providing data about luminaires, energy measurement, color control, fault diagnostics, and emergency. Most recently, the release of the D4i specification now extends to wireless technology and supports integral sensors and controllers when paired with the Zhaga Book 20 standard. Critically important, interoperability is verified through testing and certification. Efforts are ongoing to enable functionality with multiple wireless communication protocols including Bluetooth mesh, Zigbee and Thread. The elephant in the room is us, and it's a lonely place to be. We do not have a seat at the decarbonization table. Our ongoing competition between proprietary controls technologies has made us irrelevant in the eyes of most decision-makers. I submit that our focus should be on industry alignment to expand opportunities overall, 18

designing lighting

Putting aside the most well-known integration use cases (e.g., realtime feedback from sensors to room reservation systems and HVAC systems), there are a multitude of new market drivers. For example, the highly nuanced dimming of individual luminaires in consideration of their room type and occupant needs enables maximum load shedding at peak hours. Digital interaction with Grid-interactive Efficient Buildings helps to manage electrification including integration of renewable energy and batteries. Monitoring lighting energy consumption in real-time helps owners to report progress and compliance with the rapid proliferation of Building Performance Standards (BPS) such as Local Law 97 in New York City, where the consequence of non-compliance with carbon reduction requirements will be heavy fines. LL97 has received the most visibility, but according to the National BPS Coalition, there are 40 municipalities that have adopted similar requirements. So how do we make this happen? Spec it. Defend it. Learn, and teach. For many years I've heard our specification community pleading for interoperability and reliability. Avraham Mor, CLD, IALD, says it well: "The world is going digital all around us with every kind of technology imaginable, yet the industry is still defaulting to 0-10V dimming. It's way past time for the lighting industry to make the shift to digital, addressable, and interoperable controls technology. Designers have the responsibility to commit to the learning curve and advocate for this in our specs. Morlights can't do it alone, but we can be part of the solution." The next era? Considering decarbonization is mission critical to mitigating the climate change crisis, it's difficult to imagine the next era. Whatever it is, I can guarantee that digital and interoperable technology will be central to success. P

LIGHT AND HEALTH

Be Creative! Three Approaches to a Tailored Lighting Intervention for Improving Sleep-Wake Cycles in Dementia Patients By MARIANA G. FIGUEIRO AND DAVID PEDLER

Light and Health Research Center at Mount Sinai

In previous Light and Health Research Center (LHRC) contributions to designing lighting (dl), we described studies employing tailored lighting interventions using circadian stimulus (CS) to improve sleep using single devices among nursing home residents living with ADRD and home-dwelling patients living with a related neurodegenerative disorder, Parkinson’s disease (PD). Those studies showed that, despite the difficulties commonly encountered when delivering therapeutic lighting interventions in the field, the simple principle of promoting brighter days (i.e., high CS), dimmer evenings (i.e., low CS), and darker nights can significantly improve objectively and subjectively assessed sleep outcomes. Because patient compliance can pose formidable challenges to the efficacious application of nonpharmacological light therapies in controlled settings, the key to success in field studies lies in being able to deliver the treatment as participants go about their daily activities.

This study followed the same general approach described in our previous two articles but differed in its use of three separate lighting systems/devices among 14 cognitively impaired participants with sleep disturbances residing in three separate assisted living and memory care facilities in Westborough (5 participants), Northborough (4 participants), and Medway (5 participants), Massachusetts.

Study Method Following specifications proven in previous studies,1, 2 we delivered a tailored lighting intervention (TLI) designed and specified to provide a robust light–dark pattern to maximally stimulate the human circadian system based on the mathematical model of CS developed by Rea and colleagues.3, 4 Our research has shown that providing a criterion CS value of 0.3 improves sleep, mood, and behavior in ADRD and PD patients.5, 6 The TLI employed

designing lighting

LIGHT AND HEALTH were used at the Northborough site. Custom built by the LHRC, the trays house an LED array and measure (l × w × h) 64 cm × 53 cm × 4 cm. The participants were assigned to seats facing the tabletop light trays for breakfast and lunch over the course of the study. As measured in the laboratory at eye level when seated with a single dinner plate occluding the tray's surface, the active intervention delivered 602 lx and a CS of 0.456 and the control condition delivered 65 lx and a CS = 0.064. As the trays could deliver only a single condition, they were alternated between the active intervention and the control. Ambient room lighting. The retrofit of the dining/community room lighting at the Medway site was performed with assistance from the researchers. In the area that received the retrofitted lighting, the mean illuminance measured at the eyes for occupants seated at the tables was 307 lx and the mean CS value was 0.28. The retrofit employed six 30-in diameter dimmable, direct/indirect circular (5-in lens aperture) ring pendant Figure 2. The experimental protocol followed at the Medway facility. The experiment lighting fixtures (3000 K; Sketch, Axis at the Westborough and Northborough facilities followed the same protocol and Lighting, Lasalle, QC, CA) suspended occurred between July and December 2022. over the dining/community room's six tables and four 4-ft linear dimmable, direct/indirect (2-in lens aperture) (3000 three device modes (light tables, light trays, and retrofitted K; Beam 2, Axis Lighting) fixtures mounted on adjacent, ambient room lighting [Figure 1]) over two 8-week opposing walls. The retrofitted system was driven by a intervention periods separated by a 4-week washout. programmable power/relay pack and on-screen controls The TLI’s (high CS) efficacy was compared to that of a (Acuity Brands, Conyers, GA, US) to deliver a CS of 0.4 non-therapeutic placebo (control) lighting intervention from 07:00 to 17:00, gradually transitioning (from 17:00 to (low CS), and both lighting conditions were compared to 18:00) to a CS <0.1 from 18:00 to bedtime. As confirmed via baseline data collected in the existing facility lighting at spectroradiometer, the actual average vertical illuminance the beginning of each 8-week intervention period (Figure (measured at eye level when seated at the table) was 520 lx 2). The study participants wore actigraphs on their wrists (mean CS = 0.37) for the intervention lighting and 135 lx (CS and completed questionnaires assessing depression, sleep = 0.1) for the control condition. quality, and sleep disorders during the first (baseline) and final assessment weeks of the two intervention periods. Results

TLI Modes

Light tables. Custom-built light tables (XtraLight, Houston, TX, USA) were used at the Westborough site. The tables measure (l × w × h) 156 cm × 99 cm × 13 cm, with a luminous area on the tabletop measuring 137 cm × 79 cm and sitting 76 cm above the floor. The light is provided by 13 lightemitting diode (LED) strips measuring (l × w) 61 cm × 6 cm (model BB0040, ver. 001.1, XtraLight) recessed 9.5 cm beneath the tabletop and covered by a 1 cm thick diffused acrylic lens that serves as the table's durable work surface. The active TLI (measured in the lab) provided 1887 lx and a CS of 0.625 at eye level, and participants were encouraged to sit at the light tables whenever they were using the facility’s dining/community room. Light trays. Light trays serving as light-emitting dining/work surfaces and fashioned after a conventional cafeteria tray

The actigraphy data showed that participants slept significantly longer under the active condition after the TLI compared to baseline (p = 0.02) and sleep start time was significantly earlier after the TLI compared to baseline (p = 0.01). The questionnaires revealed that sleep quality scores improved significantly after the TLI compared to baseline under the active condition but not under the control condition (p = 0.01 and p = 0.24, respectively). Depression scores also improved after the intervention compared to baseline under the active condition but not under the control condition (p = 0.01 and p = 0.48, respectively), as did the sleep disturbance frequency and severity scores after the intervention compared to baseline under the active condition (p = 0.02). The sleep disturbance frequency and severity scores also increased after intervention compared to baseline under the control condition (p ≤0.03). The results are summarized in Table 1.

Table 1. Summary of results. The bold arrows enclosed in circles represent statistically significant results. Better outcomes are shown in green, worse outcomes are shown in red.

Takeaways The key takeaways from this study are: •

Bright days, dim evenings, and dark nights improve sleep and mood in dementia patients, regardless of what metric you use or how you deliver light to the eyes.

•

Don’t start with the lighting system, start with the patient’s daily activities and tailor the intervention so that the light is being delivered to each person passively.

•

Ceiling lights delivering direct/indirect light can be used to deliver circadian-effective light. If the budget does not allow for tunable systems, simply use dimmers so light levels can be increased during the day and reduced in the evening.

•

Be creative and think beyond the ceiling! The smaller size and flexible characteristics of LEDs can help designers create innovative ways to deliver circadian stimulus in a comfortable and effective way.

TELEVISION HISTORY By RANDY REID Photo Credit: Jorrit Lousberg

The Beeld & Geluid (Institute for Sound and Vision) in the Netherlands is not just a museum. It's an intricate media archive and event hub situated in Media Park in Hilversum. This unique location is home to many working broadcast studios, including news and special events studios, creating a media city of sorts. The design of the museum is a testament to the evolution of television. To preserve the culture and heritage of this important medium, the museum incorporates daily archiving systems, implemented through interactive installations, gamification, and other activities happening in the studio. The project was a collaborative effort involving several parties, each contributing their unique expertise to create an immersive and interactive experience for visitors. Michel Nols and Koert Vermeulen of ACT Lighting Design were responsible for the comprehensive lighting design, which included all light sources in the museum, including those integrated into the furniture and functional lighting in the ceiling. The lighting for the furniture was provide by Ata Tech. Pharos Architectural Controls supplied the dynamic lighting controls which were integrated and guided by Rutger van Dijk. The interactive content was designed by Kiss the Frog and was integrated with the lighting to create an engaging and interactive experience for visitors. Tinker Imagineers was responsible for the complete spatial and exhibition design, as well as the audiovisual design. 24

MEETS INNOVATION The ACTLD lighting strategy was developed in three parts, with the screen being the protagonist in the media studio, as the content and screens were the primary storytellers throughout the experience. The second part of the strategy involved creating a counterweight to bring forward the image. This was achieved by implementing lighting that grazes and gives an architectural context in which the screens can come forward. The third part involved meticulous integration of lighting in all the furniture, creating graphics throughout the whole experience.

and pixel mapping, creates a one-of-a-kind visual experience.

This three-level approach allowed for easy control of these layers as desired. The team had full control over color temperature and light, enabling them to create different moods and effects. However, due to changes in some of the rooms, they had to adjust their design several times.

Layers of Light

Media Reactor The museum incorporates a unique feature called a 'media reactor,' designed by Richard Vandy of Tinker Imagineers. This innovative element fetches video content from the media archive in real-time and projects it onto various screens throughout the space. The video clips move across the different screens, travelling through the space. The media reactor itself is composed of video projections displayed on black frames. The lighting design included an aluminum frame with LED lines mounted on different levels, creating a pixel strip behind a fabric. These frames are then translated into pixelated LED strips, diffusing the image while maintaining the integrity of the original video content. The team had to carefully position the lights to create the desired moods and effects. This flow of real media images, a combination of video

The audio component of these stories is delivered through a surround system integrated throughout the museum. This space is multifunctional and located next to the media exhibition. Upon entering the museum, visitors receive an avatar that accompanies them throughout their visit. The entirety of interactive experiences are synced with the visitor, through an app and facial recognition systems as the visitor travels throughout the space.

The ceiling area was crowded, making it a challenging puzzle for the design team to find optimal spots for mounting luminaires. The ceiling features curved lights and small Rosco cubes, and spotlights were added to supplement the functional lighting. Together this design created various layers of light. The Pharos DMX-controlled system allowed full control over color temperatures, enabling the team to create different settings for various scenarios such as regular museum operations, events, and maintenance work. This flexibility was crucial in ensuring that the lighting could be adapted to suit different needs and create different atmospheres as required. The Pharos system allowed the user to have a digital schedule with all fixtures mapped out, providing a seamless way to control and program the lighting for each area.

Furniture Integration One of the unique features of this project was the furniture lighting. Tapelight mounted to the bottom of furniture created a soft glow on the floor, contributing to the ambiance. designing lighting

Michel also shared some images of the welcoming space where visitors can take pictures against a green screen and create a digital passport. This passport can be used to log into every interactive installation or screen in the museum, providing a personalized and immersive experience for each visitor, in addition to the many interactive features triggered by the facial recognition system. One of the challenges faced by the team was balancing the general lighting moods with the effectiveness of video projection installations and face recognition implementations. Too much light could diminish the impact of these installations, so careful consideration was needed to strike the right balance. One such installation is a newsroom where visitors can become newscasters in a television studio. The lighting in this room was designed to mimic the clinical brightness of a broadcast studio. Another studio is designed to resemble a stage and theater performance, allowing visitors to become directors of their own movie scenes. A third space is inspired by a Tokyo supermarket shop, featuring vibrant colors and dynamic lighting. One of the highlights of the museum is a game room, inspired by 1980s arcades. The room features UV lights to create a glowin-the-dark effect on the scenery, and an interactive video floor adds another layer of engagement for visitors. The project’s success hinged on the flexibility and convenience of its installation setup. The team could simply plug in, open the Pharos system, and everything was up and running. The lighting scenes and programming were all controlled from the files control system. If adjustments needed to be made, it was just a matter of making a few easy changes to the software. 26

designing lighting

This system was particularly beneficial because the design was developed in different phases. The focusing happened in four or five stages, providing the team with the flexibility to come in with no more than a laptop and handle everything. One of the key points Michel emphasized was that this project was very much a collaborative effort. Six to seven different parties put their heads together to make everything work - from lighting to interaction design, video content, gamification, server systems, and developing archiving systems. The Beeld & Geluid (Institute for Sound and Vision) faced several delays due to the Covid-19 pandemic, extending the design process to several. Despite these challenges, the team managed to create a stunning and interactive space that is both educative and immersive, standing as a testament to the power of resilience, adaptability, and the magic of storytelling through light and media.

LIGHT WITHIN Exploring the Translucent Facade of The Perelman Performing Arts Center By RANDY REID Photo Credit: Martin Hidalgo for designing lighting(dl) 30

designing lighting

COVER STORY

The world of architectural design is constantly evolving, with innovations emerging that redefine our understanding of space, materials, and aesthetics. Recently, a novel approach to lighting building facades has surfaced, characterized by the ingenious use of translucent marble as a primary material. This has the potential to change the way we perceive buildings, especially during the evening hours. The Perelman Performing Arts Center (PAC NYC) in Manhattan chose this unique approach for their facade. This project not only showcases the possibilities of contemporary design but also the challenges that come with it. Suzan Tillotson of Tillotson Design Associates discussed this architectural marvel. The conversation revealed the practical aspects of the design process, the hurdles faced, and the final impressive outcome. At first glance, the building facade captivates observers with its luminous glow. This isn’t a result of external lighting fixtures shining on the surface. Instead, the light originates from within the facade itself, emanating a soft, consistent illumination that highlights the building’s unique structure and design. It’s a scene that can make passersby stop and admire, pondering the techniques behind such an illumination. To achieve this luminosity, the facade employs a special construction technique. The building is adorned with translucent, veined marble, giving it an elegant appearance in the day with its bookmatched stone. This marble, sourced from the same Vermont quarry as the U.S. Supreme Court Building and the Thomas Jefferson Memorial, is a key component of the high-performance facade.

The marble used is half an inch thick, a deliberate choice to highlight the depth of the veining. Any thicker would risk delamination due to the stone’s natural expansion and contraction. To counter this, a layer of glass is laminated to each side of the stone, creating a seal that prevents any moisture from reaching the marble. This precaution stops the stone from hydrating and dehydrating, which could cause it to bow. The result is a translucent sandwich of glass-stone-glass. Each sandwich unit measures 3 feet in height and 5 feet in width. The outermost piece of glass has a microtexture similar to honed stone. So convincing is this texture that many people don’t realize the outer surface is actually glass, not stone.

designing lighting

This three-layered composition is often referred to as an insulated glass unit (IGU). The unique composition allows interior light from chandeliers to pass through the marble, creating a mesmerizing effect that is crucial to achieving the kind of radiant glow that sets this design apart from conventional structures. Custom-made chandeliers were designed and aimed at the IGU from the inside. The lighting was carefully calibrated to create an even illumination across the facade. The assembly of the chandelier was made by Flos, while i2Systems was responsible for creating all the LED boards, furnishing the drivers and optics, and making all the slab edge fixtures. The chandeliers, which are five-foot-long bars of LEDs in a highly

provided had to be absolutely precise.” The color temperature of the light was 3000K, chosen to complement the amber tint of the marble. The lighting remains constant, creating a mesmerizing effect on the facade. The building is separated by a 4-foot floor slab/plenum; a 9’ floor slab/plenum exists at the top. Obviously, the light could not penetrate the structure separating the two floors. Supplemental lighting from i2Systems was used to create an illusion of light bleeding through the floor. From an exterior point of view, these slab edge lights prevented any unwanted shadows. The timing of the lighting was also crucial. This building, illuminated by its own skin, stands out, especially during twilight hours. As the sun sets and natural light dims, the building begins to shine, serving as a beacon of modern architectural prowess. The team spent many hours observing the sunset to program the perfect timing for the lights to come on. As the sun sets, especially on the west facade, the light on the material is much brighter than the light that can be pushed through it due to energy code limitations. Hence, they needed to wait for the ideal moment when the sun had completely set before they could turn the lights on to their maximum brightness. Another challenge was dealing with the refraction off the glass from wayward light trespassing from streetlights and other buildings. This is where close collaboration between the lighting design team and the owner prevented a problem. While the interior glass has a very high specular reflectivity, the exterior has more of a matte finish to help diminish the reflection of stray lumens. Despite not being able to conduct a full-scale mockup prior to construction, the team was able to successfully execute their vision. They tested uniformity using a white fabric scrim in a theater but only had one small piece of marble for testing. They were able to overcome these limitations to achieve their desired outcome. The project began in 2016 and was recently completed. The facade did not turn out to be a completely luminous box. This was expected by Tillotson’s team, as each 3’ x 5’ marble slab was unique. Despite this, they were extremely satisfied with the outcome. Thoughtful design and intricate planning are ushering in a new era for architectural facades. These exteriors, previously just shields against the elements, now serve as evocative canvases that narrate tales and highlight human creativity. polished stainless steel finish, are arranged in a V-shape. There are ten chandeliers per side, per level, totaling 80 chandeliers for the entire project. Each one has a specific angle of light emission. The team had to calibrate all the optics to ensure light reached all areas of the facade evenly, including down to the floor and slab edges. If the angle and dimming was not perfect, it would affect the illumination on the facade. A 9-degree beam of light might be perfect for a particular chandelier, but a 13-degree beam would cause too much glare or miss the wall entirely. Bars positioned at a direct angle to the glass were dimmed more than those angled downward. The downward-facing bars maintained full brightness for consistent lighting. Suzan emphasized, “There was no room for error, and every product

The Perelman Center's facade exemplifies sustainable lighting, embedding the light source within the structure. This innovation leads to significant energy savings, less light pollution, and a seamless blend of architecture with its environment. Translucent marble, central to this innovation, heralds exciting potential for future architectural designs, envisioning cities where buildings internally illuminate, reflecting culture, history, and achievement. Tillotson's pioneering work on this facade is not merely an architectural achievement but signifies the progressive trajectory of design. As design horizons expand, our urban spaces become not only functional but also mirrors of our collective aspirations and creativity. P

The Norton Museum, located in West Palm Beach, FL, stands as a testament to the confluence of architecture and lighting. George Sexton Associates was brought on board by the museum in collaboration with Foster + Partners. George Sexton and Owen Brady of George Sexton Associates shed light on the careful thought that went into illuminating both the interior and exterior of this museum. The history of the museum is quite fascinating. Originally constructed in the 1940s, the building was designed in an art deco style. However, it underwent a significant transformation in the 1990s during a period of widespread museum construction. The museum commissioned Foster + Partners to design an addition and his approach was radical. He transformed the 1990’s addition and reorganized the spaces in a more classical manner. This process also involved renovating the original art deco building. The result was a completely new museum that maintained its historical

designing lighting

roots while embracing modern design principles. One of the most significant changes was the relocation of the entrance to face the Dixie Highway, one of Palm Beach’s main roads. This gave the museum a prominent presence in the community and made it a visual landmark for those entering or leaving Palm Beach. Starting with the exterior, George emphasized the intricate balance of the lighting. The exterior of the Norton Museum is a testament to the power of subtle illumination. Rather than floodlighting the building, the design team opted for a more nuanced approach, allowing the interior of the building to glow from within and serve as a lantern. The approach was not only aesthetic but also aimed at addressing issues like light pollution, light trespass, and energy conservation. Features such as sculptures, water elements, and landscaping added layers to the external illumination. This approach endowed the museum with a distinct nighttime identity. A major highlight of the museum's architecture is the banyan tree. Owen pointed out that the building’s exterior

design respected the tree, a much-loved feature, preserving its presence. The tree was illuminated using both ground-mounted uplights and tree-mounted downlights. This illuminated the internal branching structure and the canopy, creating a breathtaking visual. The idea of capturing the building's glow from within was crucial. The walls seen through the glass facades were washed in light, their reflection captured in the metal roof canopy overhead and mirrored once more in the water feature below. A standout feature is the Claes Oldenburg sculpture, which, with the careful use of ambient light, stands out without the need for dramatic spotlighting. George specified B-K Lighting fixtures for the banyan tree at 3000K. An outdoor rated, ETC fixture illuminated the Oldenburg sculpture,

while a linear luminaire from Acolyte wrapped around the base of the museum for site lighting. Inside the museum, the lighting design continues to impress. The walls seen through the glass facades are washed with light, creating a reflection in the metal roof canopy overhang and in the water feature below. This creates a beautiful interplay of light and reflection that enhances the architectural features of the building. The gallery lighting system was designed keeping flexibility in mind. With museums often rotating exhibits, the lighting system should easily adapt to the evolving displays. The design foundation was a pattern of lighting tracks in the ceiling, providing angles of light to reduce glare, and control both quantity and distribution of light. In the realm of minimalist architecture, as exemplified by Norman Foster’s designs, lighting integration presents a significant challenge. The architecture’s discreet and highly refined nature necessitates an unobtrusive yet effective lighting solution. This hurdle was overcome through a close collaboration with LightLab, leading to the utilization of ‘Museum Line’ track and monopoint luminaires. George has a deep-rooted connection with this product, having contributed to its development with LightLab for the Museum of Modern Art, New York design many years ago. The ’Museum Line’ fixtures, an LED track system, ingeniously integrate the transformer into the track. This design innovation allows for fixtures that are not only smaller but also more discreet, seamlessly blending into the minimalist aesthetic.

One of the standout spaces inside the museum is the Shapiro Great Hall. The hall boasts concealed elliptipar® uplighting around its four sides and highlighting the complex vaulted ceiling. The lighting design was carefully executed to be invisible to the naked eye, yet impactful in its illumination. Tivoli luminaires are at the base and a skylight in the center add to the hall's allure. Acuity’s nLight control system is used throughout the museum utilizing a variety of scenes for different occasions, from daily use to special events. The Norton Museum stands as a glowing beacon in the heart of West Palm Beach, a fusion of historic architectural elements and cutting-edge lighting design. The collective vision of George Sexton Associates and Foster + Partners has transformed it into a radiant masterpiece that continues to captivate visitors and experts alike. It is an example of what can be achieved when thoughtful design meets innovative execution. It’s not just about illuminating a space; it’s about enhancing an architectural experience through light.

AMERICAN ART MUSEUM’S

The Smithsonian

Lighting Curator Shares His Secrets

Photo by Albert Ting

The Smithsonian American Art Museum (SAAM) is one of the most prestigious art museums in the world, with a collection spanning from colonial portraits to contemporary installations. The museum is also a leader in using innovative and energyefficient lighting solutions to enhance the visitor experience and preserve the artwork. The museum’s lighting curator, Scott Rosenfeld, shared some of his secrets as a lighting expert for SAAM.

reached the end of its life. It no longer provided sufficient illumination for the works of art. Rosenfeld decided to upgrade to a state-of-the-art LED system.

Rosenfeld has been working in museums for 30 years and has participated in several lighting transformations within the Smithsonian.

To do so, he hired renowned architectural firm Selldorff Architects, who in turn hired Eileen Pierce of Pierce Lighting Studio as the consultative lighting designer. Drawing on his 30 years of experience, Scott did much of the lighting fixture work, with input from Pierce Lighting Studio on the concept design, proof of concept, calculations, modified specifications and mounting details for the (4) custom pendant configurations of the track layout and fixed focus fixtures.

One of the most recent and significant of these was the renovation of the Lincoln Gallery, which displays dynamic and interactive artworks that use light, sound, and motion. The gallery was previously lit by an MR16 halogen system that had

"How do we create bright, even light with low glare?" Scott asked rhetorically, highlighting the central challenge of lighting the museum. Showing a photograph of the gallery, he explained, "You can observe that the lights aren't blinding or

overwhelming. There's an abundance of light, but the sources are almost invisible to the viewer. This is achieved because our light sources are deeply baffled, employing both reset and cross-baffling methods. The uplighting we've integrated contributes significantly to the ambient lighting of the space." The Lincoln Gallery is dynamic – the works of art change and interact with each other. Scott directed my attention to a painting, explaining, "If you turn to the artwork on your left, you'll notice that the neon plays a pivotal role in its illumination. The discontinuous spectrum emanating from the neon display on the opposite wall enhances the vibrancy and colorfulness of the artwork itself." The gallery’s uplighting provides ambient light and enhances the spatial perception. The Lighting Services Inc (LSI) luminaires throughout have a high color rendering index of 90 and a color temperature of 3000K, which are suitable for displaying artworks with vibrant colors and contrasts. Pierce Lighting Studio's track layout allows for flexible and adjustable lighting for different artworks and exhibitions. Scott worked with Ken Kane of LSI to design the track heads, which involved selecting the internal optics and focusing the adjustable track fixtures. The Lincoln Gallery lighting system was part of a much larger lighting renovation of the entire building, which involved replacing over 10,000 luminaires throughout the museum. Rosenfeld noted that these two projects dovetailed nicely – he was able to use some of the products that he had bought for the whole building in the Lincoln Gallery. Rosenfeld also shared some of his insights and challenges as a lighting curator for SAAM. He has developed a unique vocabulary of light for working in museums, which is based on an old vocabulary of floodlights and spotlights. He uses different types of LEDs from a variety of manufacturers, such as Xicato or Bridgelux, depending on the application and the artwork. Using a combination of reflectors and lenses, he can focus the light anywhere between 10 and 60 degrees. He explained, “In 2015 and 2016, we did some upgrades to save energy, but we sacrificed quality. With this retrofit, I was so pleased that we were able to go from the energy hogs of incandescent to energy efficient lighting while dramatically increase the quality of light.” 40

On the subject of controls, Rosenfeld noted that they are important, but not as important as distribution. Distribution is about being able to put the light where you want it and take it away where you don’t. This requires a tremendous amount of skill and craftsmanship. What you see in his galleries is handcrafted light – every fixture is carefully adjusted and aimed to create the best possible effect. Rosenfeld showed some examples of how he uses light to create contrast and harmony between different works in the same gallery. For instance, he showed a picture of a Basquiat painting next to a folk art painting, explaining how he used different angles and intensities of light to highlight their differences and similarities. He also showed a picture of a projection artwork that creates a ghostly effect on a red curtain, using bright light to define the edge of a bench where a visitor was sitting. Occasionally, the effects he creates with light are unintentional but welcome, such as making the visitor’s hand appear as another ghost in the projection. Rosenfeld uses a Xicato Bluetooth Low Energy (BLE) system for controlling the lighting. He chose Xicato because they had an open and documented API that was reasonably well built-out. Working with a hub-based system rather than a mesh-based system provided more flexibility and reliability. Using an iPad app to control the system, he can dim, switch, group, or schedule his lights remotely and quickly. The problem with mesh, he noted, is that it is like popcorn, with lights randomly turning on and off. Paramount to his role as a lighting curator is respecting the artist’s vision and intention, while also taking into account the conservation needs and the visitor experience. It’s a delicate balance, requiring years of experience to perfect. Rosenfeld commented that he is always learning new things and facing new challenges as a lighting expert for SAAM. One of the unique features of SAAM is that it mixes different types of artwork and artists, from the most renowned contemporary artists to those from folk and indigenous traditions. Rosenfeld does not differentiate between the provenance or the pedigree of the artist, but treats all art as art, no matter what. And, he uses his expertise to masterfully light every piece. P

SHEDDING A LIGHT

How Studio UNTLD Illuminated the Vibrant Fresno-based Restaurant

designing lighting

HOSPITALITY

“Napa Valley meets Mexico City” is how the Fresno-based Saizon restaurant bills itself. Serving contemporary American cuisine that features Mexican influences with a unique Cali point of view, Saizon’s range of flavorful food is matched only by its energetic surroundings—the design of which is equally enticing. That design hails from Los Angeles–based STUDIO UNLTD. The award-winning hospitality design firm specializes in interior architecture, furniture, and lighting, and the team is adept at cohesively bringing all three together with impressive results. We connected with Becky Becheanu, Studio UNLTD’s Lighting Designer, to get insights on how they achieved that goal with this particular project. “The overall design of Saizon leans very architectural with faux columns and beams inspired by the dilapidated concrete structure beneath an old ocean pier being used to create an internal framework,” Becheanu explains. “The finish selections and design details of the space focus on handmade textures and geometric shapes—like the blue Zellige tile of the bar face and the black plastered ‘icons’ at the interior and exterior walls of the private dining room.” Of course, lighting plays an important part in highlighting both the steadfastness of the architecture as well as the textural moments, the designer adds. “Architectural lighting is used to highlight the custom rust-effect artwork on the soffit that wraps behind the bar and around the corner above the open kitchen. Accent lighting along the walls flanking the bar and open kitchen highlight colorful murals, making their vibrancy pop.” The fixtures used to achieve the design scheme shift depending on what area of the restaurant they were focused on, to ensure each scene set the ideal mood. For example, Becheanu notes that large custom-hammered copper pendants from Cu29 foster a more intimate dining experience in the private dining room with the copper material creating an extra warmth as it reflects the light inside. Meanwhile, custom double-armed fixtures by Paul Paige mounted

designing lighting

along the spine wall of the double-sided dining banquette feature handmade ceramic shades with leather wrapped detailing at the vertical steel supports. “These fixtures were inspired by lamp posts,” she says, “that might be seen along a pedestrian pier.” Serving as distinct pieces of art within the restrooms and the adjacent corridor were custom-shaped LED neon fixtures from Luminii. “Their shapes use the same geometries employed at the black ‘icon’ walls of the private dining room.” Additionally, Lunar pendants from Virginia Sin add a pop of warm terracotta at the vanities in the otherwise darkly colored restrooms. Above the bar lounge area, large Wireflow chandeliers from Vibia were selected to reinforce the architectural, geometric feel of the space, and Grain Drum pendants from Brendan Ravenhill create a more intimate, warm light at the round dining booths in the bar area. To soften the concrete-textured perimeter walls of the main dining room, Wood Eclipse sconces from Allied Maker were installed, and then on the patio outside, Jaima pendants from Marset add a focal point above the round booths found there. Of course, the role of lighting and choice of fixtures played into the project’s overall design approach as an important part in the process. “As a primarily evening dining establishment, the lighting of Saizon needed to be ‘sexy,’ capable of low dimming and a softness conducive to the dinner experience,” Becheanu reveals. “To this end, we desired architectural light fixtures with great low-end dimming and more focused beam spreads to illuminate table surfaces and highlight specific moments and features in the space as a way to help tell the overall design story.” And lighting choices go hand-inhand with overall interior design choices, she adds, so that they are supporting and bolstering one another. In terms of what Becheanu and the team were looking to for inspiration in design and lighting for Saizon, the designer says that “they were inspired by the meeting between nature and manmade structure that occurs at an ocean pier, and the tension this meeting creates between permanence and fluidity.” Additionally, the client envisioned incorporating graffiti-inspired art in the space, she adds, which informed the style and direction of the colorful murals that captivate guests’ eyes upon entry. “Much of our inspiration for Saizon came from the desire to explore a range of tactility in surfaces and finishes (emphasized with lighting),” Becheanu concludes, “in order to create a richness of depth that could support a variety of dining experiences and rhythms throughout the room.” P

A Luminary Vision Lighting the Way in Modern Residential Design By RANDY REID

Photographer: Austin Ashline, Future Home Photo

When one envisions a masterpiece of contemporary residential design, the play of light—both natural and artificial—often stands out as the crowning touch. Here, Todd Walling, Principal, LIGHTWORKS, sheds light on the nuances of lighting design, its challenges, and the beauty it brings to a La Jolla waterfront residence.

The House with a Vision It's not just any home, but a creation by Blue Heron, a significant player in the Las Vegas housing market. Breaking into the California domain, they crafted a home built on spec, infused with their characteristic grandeur. Although built to sell to an

unknown buyer, the house carries the unique hallmark of Blue Heron's design and standards.

Integrating Smart Systems One of the distinctive elements of this projects is that it was designed with a full Savant smart house system, including Savant Lighting and audio-video control. While the natural light control and shading solution was courtesy of Lutron, Savant held the reins for lighting control. A noteworthy aspect of the project was its shift towards Savant lighting control commissioning. While Lutron is more familiar territory for Todd's team, they found Savant's approach to be quite user friendly. The main distinction lies in the programming angle and how different loads are assigned. While this might seem nuanced and intricate to the uninitiated, from a homeowner's perspective, the controls are intuitive, with touchscreens offering an interface reminiscent of Lutron's palladium keypads. Todd explained, “It was a bit unusual to commission for an unknown

In this case, we just made common-sense assumptions.” As the conversation moved outdoors, Todd described the minimalist yet impactful landscape lighting. The floating fire features, a recessed exterior sofa set with underlighting, and a distant bar with knee space lighting are some of the prominent elements. The underlighting for the fire pit and the couch was supplied by Q-Tran. On the landscape lighting front, FX Luminaire was the chosen brand, with a particular emphasis on uplights. The house’s location on a cliff overlooking the ocean with direct exposure to the elements presented another challenge. USAI's three-inch bevels were chosen because of their natatorium finish which is resistant to the salty air constantly blowing through the open house. All their trims are lensed and sealed, which was an important consideration. The deck was graced with square lights, also from USAI. The wine bar, on the other hand, was adorned with tape light from the top, uniformly lighting up the area, courtesy of Q-Tran. Todd indicated that the project encountered minimal supply chain disruptions. What were once three-to-four-week lead times extended to six to eight weeks, but these delays were still within manageable limits. One of the biggest challenges on this job was working with a remote developer a state away. The project involved many parties, including Blue Heron and their design team, their project management team, the investors, and the builder. Each party had different opinions, so it was crucial to be solutions-driven and find the best outcome to please everyone. You have to be wondering what does a house like this cost? It sold last year for $22,500,000! P 52

DEEPER Darkness; Doing BETTER RESIDENTIAL

By DAVID WARFEL

Layers of light help spaces look and feel great, but vague or technical terminology can lead to clients less willing to invest.

Better living through light begins not with task, ambient, or accent light, but with beneficial darkness and light for our hands. Our next evolution as a profession begins when we understand that clients cut the lighting budget because we failed to establish appropriate value, instead scaring them or boring them with terminology that should stay in the studio. We know that the right light can transform lives, that thoughtful lighting design can make architecture look and function better, and that the wrong light or lack of light can lead to both short- and long-term negative outcomes for those who live, work, and rest in our buildings. Clients do not have this 54

designing lighting

knowledge, nor the time and energy to acquire it, and that gap leads to countless decisions made against their own best interest. Schools cut dynamic white light from the budget to save dollars. Businesses cut layers of light that could increase productivity and employee wellbeing. Homeowners cut nearly all architectural lighting, convinced that anything unusual must just be unnecessary expense. “Let’s trim the flooring budget so we can spend it on lighting.” As a meme would conclude: “…said no client ever.” It is very rare for a client to cut other areas to increase their investment

RESIDENTIAL in lighting. In our residential work, it is not unusual to see a client spend twenty thousand dollars on kitchen appliances and less than two thousand on architectural lighting for the entire home. I can offer a bit of hope from my own work with clients, and the best part is that you only need to change your words. What we know about light is critically important; how we talk about light more often determines what lighting gets purchased and installed. For an introduction into the power of language in lighting design, read the introductory article in the previous issue of designing lighting (dl). How we talk about light determines how clients value light itself. If we are to set aside dry technical terms like task and ambient and let go of fanciful language like play of brilliants, at least when talking to clients, we need language that allows us to effectively communicate both purpose and value. In this article I will look at beneficial darkness and light for our hands; future articles will dig into light for our bodies, minds, faces, places, lives, and values. As I wrote in the introduction to the series in the previous issue of dl, there is nothing sacred in my language, nor am I hopeful that I will gain followers who use my terminology. Instead, I simply want to encourage you to rethink how you talk about light and find a way that works for you—and especially for your clients. This is simply my approach, provided as food for thought.

they be. If we can boil beneficial darkness down into something that both we and our clients can readily grasp, we can effectively communicate the need for good dimming and controls, lightfiltering and light-blocking shades, and low-glare cutoff fixtures. And boiling it down need not be difficult: excess light at night (LAN) is bad for our wallets, our planet, and our bodies. Our clients pay for every lumen produced on their property, useful or not. So many homes are graced with brass-and-glass “coach house” lanterns that direct a majority of lumens into the skies or into our eyes. Besides discomfort, the end result is that our clients pay money to send light upwards that serves no practical purpose unless they often fly home on a broomstick. Why waste money when there is a better way to achieve light with respect for darkness? The light we waste at night is staggering—and staggeringly bad for the only habitable planet in our solar system. Light sent into the sky disrupts animals and plants, all while requiring the generation of electricity for no useable purpose. The end result is endangered wildlife and plants, along with increased pollution and resource extraction. Again, much of this light at night is completely wasted. Who sees the trees in your backyard after you go to sleep?

I have not used this whimsical illustration with clients, at least not yet. But the next time I endeavor to explain the benefits of darkness, this might just be more understandable than many alternatives. A full, rich, satisfying lighting experience reminds me of red velvet cake. Each layer, bonded with the right amount of icing, serves to make the whole piece taste great. What analogy can you create that clients will inherently understand?

For a number of years I shared a whimsical red velvet cake theory of lighting with my clients. A rich, satisfying lighting experience is something like a rich, satisfying piece of red velvet cake: done in layers with just the right amount of icing. Only recently have I started thinking about the plate that holds the cake, the foundation that holds all lighting: beneficial darkness. I picked up the term beneficial darkness from Edward Bartholomew, Lya S. Obsborn, and Mark Loeffler when they so eloquently pointed out how those with less power and money often lack access to good darkness. I like the term for its simplicity and clarity and its ability to communicate both what we need and why we need it. We need a certain kind of darkness, and we need it because it has benefits for our lives. I am no expert researcher and make no claim to fully understand all the nuances of darkness and how a lack of it leads to harm. Of course, neither are our clients, nor should

Light at night can be bad for our wallets, hard on the planet, and painful for our bodies. Less light can be the best lighting design strategy after dark.

designing lighting

RESIDENTIAL Finally, we need beneficial darkness for our bodies. I am astounded at the continual release of research that points to the harm of light at night light at night, from potentially carcinogenic effects to sleep disruption and nearly every kind of modern disorder. It turns out that after thousands of years of dark nights, our newfound perpetual state of twilight just is not good for us. When we talk about darkness in terms of its benefits – for our wallets, planet, and bodies – we are more likely to convince our clients to allocate resources of time and money towards preserving it. But complete darkness is not always the answer, and at some point we must introduce electric light to help us live our lives.

Simple illustrations can help convey the limited value of typical light fixtures to clients, most of whom have far more important things to do than get a PhD in lighting.

Simplifying terminology makes it possible for us to rebuild our presentations and communications around something the clients can grasp.

The first layer of electric light, for no other reason than it is most often first in our minds, is light for our hands that helps us see what we are doing so we can do it better. We might call it task light or focal glow, but simplifying the terminology to light for our hands makes it instantly understandable to most of our clients, and understanding leads directly to value. It is easy for a client to say “Let’s cut the task light” when they do not fully understand what it does. It is much harder for a client to say “I don’t need light for my hands” or “I don’t want to do better.” Simplifying terminology makes it possible for us to rebuild our presentations and communications around something the clients can grasp. I have recently begun to dabble, in my rather untrained way, with illustrations that attempt to simply communicate the value – and place – of light for our hands. For example, this first cartoonish illustration conveys that we need good strong light for our hands but that the strongest light is often lost above our heads. Showcasing lighting fixtures people know allows us to point out inherent weaknesses, thereby preparing the client for better alternatives. Historically-styled chandeliers, modern disk lights, and torchiere uplights will always put better light on the ceiling than our hands. Even the most unskilled client can usually recognize that this is misplaced effort and expense. The second sketch shows a few alternatives like recessed downlights, desk lights, and table lamps. I find it useful to illustrate a series of tasks, from which a client might see something that is important to them. If they value knitting, or cooking, or reading, then the light I propose for their hands automatically has more value. When lighting has more value, it is more likely to be funded.

Once the need for light for our hands is established, a conversation with clients about how to achieve it is much easier to begin. Too often, we skip the step that establishes value and go straight to solutions.

designing lighting

I hesitate to include a plan-view illustration in an article aimed at simplifying communication for clients. In most cases, I try to avoid showing plans to clients. Without proper training, their only ability to feel good about their decisions is to make an uninformed judgement about quantity of fixtures shown on a plan, or whether or not they are in tidy rows. This serves neither the client nor the designer.

RESIDENTIAL For a more experienced client, however, this simple plan illustration points out the weakness in strict grids of recessed downlights when lighting for their hands. The only practical way to make this work is to illuminate an entire space like a gas station canopy or big box retailer: light everywhere. If words are the key to unlocking value in lighting design, then graphics and pictures must be supportive of those words, not tangential or superfluous. A recent collaborator told us, “Nobody talks about light the way you do,” and it was meant as a compliment. This is not because we are better than other lighting designers – we have our strengths and weaknesses like every studio – but because we do talk about light differently, and deliberately so. When we talk to clients about light, the notable absence of “task, ambient, and accent” or “play of brilliants” allows space for us to talk about beneficial darkness and light for our hands.

There is a fine line between educating clients enough that they make informed decisions and so much that they tune out. That line is different for everyone; the rare technically or graphically inclined client may appreciate a plan illustration.

We do not have the perfect language of light. It grows even as I write this. We do not have all the answers to lighting design’s challenges. But I can say with confidence that changing the way we talk about light helps many of our clients understand and appreciate the value of what we do. Maybe the flooring budget will get trimmed after all. P

GET CONTROL!

LED Revolution 2.0 By CRAIG DILOUIE, LC, CLCP Craig DiLouie, LC, CLCP serves as education director for the Lighting Controls Association (www.LightingControlsAssociation.org), a council of NEMA dedicated to educating the public about lighting controls.

Everywhere, we see signs the LED revolution has won. An argument can be made, however, that this mature lighting technology is simply entering its next phase of market opportunity. Call it the LED Revolution 2.0. Over 20 years, this technology utterly transformed lighting and control and the industry at large. It dominated new product development, first matching the performance of traditional luminaires and then exploring entirely new designs and capabilities to add value. Energy was always the main driver, however, resulting in a race for efficacy that has been largely realized. Utility lighting rebate programs embraced the technology. The latest energy codes assume heavy, if not exclusive, use of it. In the residential market, the Biden Administration’s decision to eliminate the Energy Independence and Security Act of 2007’s exemptions and enforce its backstop provision is eliminating the large majority of remaining incandescent (halogen) general-service lamps. In the nonresidential market, a movement to ban mercury has resulted in seven states targeting fluorescent mercury-containing lamps. Due to its advantages, LED has been widely adopted in both new and existing construction. The latest Department of Energy (DOE) solid-state lighting energysavings forecast in December 2019 estimated 72 percent

LED penetration in the installed U.S. commercial building lighting stock by 2025 (93 percent for outdoor). In regions of the country where energy costs are higher, there are signs this has already been reached or even exceeded. For example, rebate program evaluation reports by utility consulting firm DNV projected LED share of the linear ambient lighting market to be 83 to 94 percent in 2023 in Connecticut, Massachusetts, New Jersey, and Rhode Island. This is of course great news for the United States and its economy. Lighting once consumed 40 percent of the average commercial building’s energy budget; today, it is closer to 10 percent. Overall, the DOE estimates that LED lighting has reduced overall electricity demand in the country by about 5 percent. It’s also great news for new buildings. Lighting is no longer a costly utility but instead a potential building asset. Today’s LED lighting systems are highly precise, controllable, and flexible, providing a menu of capabilities and fresh benefits that 20 years ago would have been highly costly, complex, or unachievable. For lighting practitioners doing projects in the existing buildings market, however, it may feel like the party’s coming to an end. Rebate providers are re-evaluating lighting, generally the largest part of their programs.

"Lighting is no longer a costly utility but instead a potential building asset." 58

GET CONTROL!

ENERGY STAR recently announced it is sunsetting its listing for many residential LED products. The DOE has grown selective, supporting individual applications more than the category as a whole. Coming out of the pandemic into 2023, there was a feeling the industry was at a crossroads, leading many to ponder the question: What’s next? One answer is the LED Revolution 2.0. Though this time the revolution may be more about opportunity resulting from a shift in market dynamics than a change in technology. Nonetheless, it would certainly be as exciting if not more so, as it will give lighting in America opportunity to realize the technology’s full potential. It’s an optimistic outlook for lighting based on the thesis outlined below. As with the LED Revolution 1.0, the next phase once again starts with energy. The LED installed base is currently a mishmash of solutions. These range from new fixtures to retrofit kits to basic-grade retrofits using replacement lamps like TLEDs. Lighting controls, meanwhile, are not widely installed in existing construction, with the most popular control strategy, occupancy sensors, being installed in only 17 percent of commercial buildings as of 2018, according to the DOE’s Commercial Buildings Energy Consumption

Survey. In its 2019 SSL energy-savings forecast, the DOE estimated connected lighting—LED lighting systems with integrated and networked sensors and controllers— would achieve a 7 percent penetration in the installed lighting stock by 2025 based on current conditions. The reason for slower adoption of lighting controls is simple economics. Despite offering the utility of high energy savings, these savings are applied against a smaller LED load, which impacts direct return on investment. Upgrading first-generation LED systems to secondgeneration LED systems with advanced controls would save large amounts of energy. This includes customized lighting designs, new luminaires, networked lighting controls, luminaire-level lighting controls, tunable lighting, and integration with other building systems such as HVAC and plug loads. Looking at networked lighting controls alone, the DesignLights Consortium (DLC) has estimated that widespread adoption could reduce average lighting energy consumption by nearly one-half. In 2023, the DLC published a study that underscored the energy savings potential of networked controls and recommended revising energy efficiency incentive models to capture the full benefits of controlled lighting, including pairing with HVAC systems in large buildings.

designing lighting

GET CONTROL! Using Connecticut and Arizona as regional models, the study concluded that the benefits of acquiring all cost-effective savings from networked lighting controls would be significant enough to make a noticeable impact on utility efficiency program budgets. Businesses in Connecticut could receive almost $1.2 billion in net benefits by 2030, while businesses in Arizona could receive net benefits of $217 million. Currently, roughly a third of lighting rebate programs incentivize networked lighting controls based on the DLC’s Qualified Products List for NLCs, with the majority encouraging networked control via a luminaire rebate adder. Lighting rebate programs evolve with market changes to capture significant energy savings. As rebate program administrators find increasing LED saturation in their territories, they are likely to examine new sources of energy savings. Likely candidates include those listed earlier: upgrading first-generation LED systems to second-generation technology, networked lighting controls, luminaire-level lighting controls, integration with other building systems such as HVAC and plug loads, and possibly lighting design approaches. Some rebate programs may tie these concepts together as requirements or packages. Rebates are a venerable tool for lighting practitioners to gain acceptance on lighting upgrade projects by reducing initial cost. As such, they are highly influential in market demand for retrofits. Decarbonization will enhance the incentives for deep retrofits. An increasing policy focus on decarbonization may lead to premium lighting and control options becoming more financially attractive. At the national level, electrification of transportation

is predicted to impose increasing demand for electric power. At the more local level, requirements for reporting carbon emissions and either offsetting or paying financial penalties for exceeding carbon caps may further incentivize energy efficiency and building data. Where they exist, these policies tend to focus on achieving net-zero by 2030. As these policies may be enacted at the city level, we may see a distinct market differentiation between urban and non-urban areas. Among leading commercial properties, there is a sentiment that minimizing energy costs and the carbon footprint can generate significant value in terms of attracting and retaining high-quality tenants. Meanwhile, energy codes may evolve to become more focused on carbon savings and/or performance. As this meta trend develops, the most robust lighting and control options may become more attractive when the ROI calculation includes all associated costs and incorporates applicable value that does not provide a direct ROI. The LED Revolution 2.0 is a big opportunity for quality lighting, lighting controls, data, and the full range of LED capabilities. The primary purpose of lighting systems is to serve people and realize the owner’s organizational goals. As such, upgrading remaining traditional and existing LED installations with today’s state-of-the-art lighting and control offerings represents a major opportunity. This opportunity includes designing lighting and control systems that take advantage of the full range of today’s LED capabilities and benefits, from circadian lighting to precise optics to color tuning to data to advanced controls and more. Overall, the LED revolution may have won, but market conditions may be setting the stage for its next exciting phase. P

NANOMATERIALS FOR LEDS New Low-Cost, Energy-Efficient Light Sources

By JUAN DAVILA Light-emitting diodes (LEDs) are an unsung hero of the lighting industry. They run efficiently, give off little heat and last for a long time. LEDs are a ubiquitous presence in our lives. They have replaced almost all forms of lighting devices we used before. This has been possible primarily because of the efficiency and long life of LED lamps. The field of nanomaterials is revolutionizing LED lighting

technology. The use of nanomaterials can significantly enhance the efficiency, performance, and lifespan of LEDs. Now scientists are looking at new materials to make more efficient and longer-lived LEDs with applications in consumer electronics, medicine, and security. Thanks to the outstanding optoelectronic properties, advanced nanomaterials have received increasing attention from

designing lighting

both academia and industry. In recent years, intensive effort has been devoted to developing high-performance nanomaterials, which enables huge potential in wide optoelectronic applications, particularly for light-emitting diodes (LEDs) and solar cells (SCs). The investigation on luminescence materials and metal nanomaterials is an important complementary field to LEDs and SCs. Lead halide perovskite nanocrystals with different halide ions can lead to color-tunable emissions in the visible window with near-unity photoluminescence quantum yields. Extensive research has been carried out for optimizing the synthesis of these nanocrystals for the last 7 years, and thousands of research papers have been reported. However, due to the ionic nature, these nanocrystals formed instantaneously and hence, their growth kinetics could not be established until now. Researchers from the U.S. Department of Energy’s (DOE) Argonne National Laboratory, Brookhaven National Laboratory, Los Alamos National Laboratory, and SLAC National Accelerator Laboratory report that they have prepared stable perovskite nanocrystals for such LEDs. Also contributing to the effort was Academia Sinica in Taiwan. The team claims it is possible to create bright red, green, and blue LEDs with the MOF-stabilized technique. According to them, it is also possible to create them in various shades of the three colors. They have demonstrated, for the first time, that by stabilizing perovskite nanocrystals in MOF, they can create bright and stable LEDs in a full range of colors. It is possible to create LEDs of different colors, and improve their color purity while enhancing their ability to generate light.

Light-emitting diodes made from perovskite nanocrystals embedded in a metal-organic framework can be created at low cost, use earthabundant materials and remain stable under typical working conditions. Perovskites are a class of material that share a particular crystalline structure giving them light-absorbing and light-emitting properties that are useful in a range of energyefficient applications. This is a more efficient and potentially lower-cost alternative to materials used in current LEDs. One of the most appealing parts of perovskite LEDs is the way they are manufactured, which requires much less energy than producing conventional inorganic LEDs used for lighting

today. Conventional LEDs are made from a piece of a single crystal, which is very difficult and expensive to produce and often requires ultrahigh vacuum systems and temperatures of more than 1000 degrees Celsius. Perovskite materials are typically made at temperatures below 100 degrees Celsius, and formed from solutions in a process similar to inkjet printing. If the technology were to be commercialized, it would likely result in a significant reduction in the energy required and carbon footprint of these electronics, both in their manufacture and operation. The emerging family of lead–halide perovskite (LHP) nanocrystal emitters has shown impressive achievements in solid-state light-emitting applications. With luminous efficiency comparable to that of organic light-emitting diodes, LHP lightemitting diodes (PeLEDs) have demonstrated a wide colour gamut with high colour purity and a widely tunable range of

emissive wavelengths across the whole visible range. In addition to this new class of LEDs, further advancements are being made in quantum dots (QDs), nanophosphors, nanowires, and graphene. Quantum dots (QDs) are nanoscale semiconductors and have the ability to fine-tune light when voltage is applied. They are used to improve color quality in LED displays and lighting. QDs can be engineered to emit light at very specific wavelengths, allowing for LEDs that can produce highly saturated colors. Nanophosphors are nanoscale phosphorescent materials that can convert the blue or UV light emitted by an LED into longer wavelengths, creating white light. Nanophosphors have a higher quantum efficiency and allow for better color control compared to traditional phosphors. The use of nanophosphors

in LED lighting technology has several advantages. For instance, they exhibit reduced concentration quenching effects and have a great potential to enhance luminescence efficiency and tunability. However, there are also challenges associated with their use, such as the need to control the size, crystal quality, and agglomeration state of the nanocrystals. Nanowires are used to create LEDs with a larger surface area, which can result in more efficient light emission. Nanowire LEDs can also be made flexible, opening up new possibilities for flexible displays and lighting. Nanowire LEDs are more efficient and have a longer lifetime than traditional lighting devices. They also offer the potential for further improvements in efficiency, material consumption and material tuning. The development of nanowire LEDs is expected to lead to more efficient LED-based solid-state lighting solutions. This technology eliminates the use of hazardous materials and increases lifetime and efficiency through the elimination of phosphor. The polychromatic nanowire LEDs also provide greater opportunity for tailoring light depending on need. Graphene is a nanomaterial, an atom-thin sheet of carbon which has been found to have numerous applications. Scientists have discovered that adding graphene to LEDs enables them to operate more brightly. This is because a dose of graphene oxide can effectively dissipate the extra heat that LEDs emit as they get brighter. In practical terms, this means that LED bulbs with an additional coating of graphene can achieve the same brightness as standard LED bulbs, but with a lower wattage. This makes them around 10% more energy efficient. In summary, the integration of graphene into LED technology not only enhances brightness and energy efficiency but also opens up possibilities for flexible and miniature light sources and displays. All these advancements are not only beneficial for energy conservation but also for reducing costs associated with lighting paving the way for more efficient, high-performing, and versatile LED lighting solutions. It’s an exciting time in the world of nanotechnology and LED lighting. P

ART BEYOND Boundaries By PARKER ALLEN

LIGHT ART

A Conversation with Artist Adam Frelin Adam Frelin began his artistic career as a teenager creating graffiti projects in his hometown of Grove City, Pennsylvania.

out in the landscape. His breakthrough with light came in 2005 during an artist residency on a cattle ranch in Wyoming.

The scale and openness of creating art this way attracted him - it was art free from the restrictions of a classroom. Surely unbeknownst to him at the time, he was laying the groundwork for his future career.

He was drawn to two perfectly shaped hills on the ranch that created a symmetrical valley in between and thought, “Something needs to go between the two to bridge the gap.” The natural darkness of the ranch led him to the idea of employing lighting.

In the mid 1990s, Frelin completed a Bachelor of Fine Arts at Indiana University of Pennsylvania. Art school was an informative experience, he noted, but not exactly what he was looking for. “The thing about going to school for art is they are teaching you how to make art for galleries. I got redirected, in a way. When I finished my undergrad, I was actually planning to switch and go into landscape architecture,” he explained. But, landscape architecture wasn’t quite the right fit either. It seemed good on the surface, but the degree of his ambition and scale was a better fit for the artistic field. His ideas were grandiose, and colleagues told him, “You’re never going to have that realized in this field.” And so he went back to school, earning his Master of Fine Arts from University of California, San Diego. His artwork began naturally gravitating towards creating pieces

Several hundred feet of aircraft cable and 80 four-foot fluorescent lights later, White Line was born, a subtle but spectacular bowing line of light that bridged the valley between the two hills. “In this darkened, dramatic landscape, here was this illuminated element that did two things. It drew attention to itself, but it also drew attention to everything around it,” said Frelin. The fluorescent light outdoors was reminiscent of moonlight, and the piece created an amazing play of light and shadow on the surrounding landscape. “It was both a thing to look at and an effect machine, in a way.” From that point forward, light became an integral part of his artistic repertoire. “I am not strictly a light artist,” he clarified, “but it is an important part of my work, and it seems to be the work that I get a lot of attention for now.” He uses it as a tool to create a particular effect that functions metaphorically to draw attention to a place or an issue.

LIGHT ART

Breathing Lights, Cities of Albany, Schenectady and Troy, NY, 2016 Photo courtesy of Adam Frelin.

The best example of this was a 2016 project called Breathing Lights, a multi-city installation in the Capital District of New York. Bloomberg Philanthropies was looking to fund projects that drew attention to civic concerns. In a meeting with a local architect and the deputy mayor of Troy, Frelin asked, “What is the specific concern or idea this could be about?” They both simply responded, “Vacancy.” Frelin wanted to incorporate the vacant buildings in the installation itself. Architect Barbara Nelson, his partner on the project, suggested using light. Frelin loved the idea, but remembers thinking that the light can’t be solid – that would just give the appearance that the vacant buildings are occupied. It has to change in some way. And so he and his team created thousands of LED light boxes, spread across 200 buildings, that slowly “breathed,” waxing on and off. The breathing lights spoke to an “underlying life force that was beneath the entire region, as if the life force was coming out in these particular nodes of the abandoned buildings.” Many of his pieces, like Breathing Lights, have an underlying story to tell – they touch on some relevant socioeconomic issue. Other pieces don’t necessarily address a pressing issue but nonetheless connect with the local environment and resonate with the people there. A great example is Extended Sunset at Penn State University. “I grew up in Pennsylvania, and I know that it can be pretty dreary in the winter,” Frelin explained. He took an image of 70

designing lighting

a sunset taken in that location and had it printed on film that was put in the windows of an auditorium. The windows were lined with LED strips, and the entire thing was hooked up to an astronomical timer so that it turned on at dusk and stayed on all night. “It was a sunset for everyone who doesn’t get to see sunsets there.” Frelin is constantly seeking out new artistic opportunities and currently has several projects in the works. As for incorporating light, he usually lets the project details dictate the direction in which he goes. The use of light is an artistic tool he has developed over the last two decades, and, like any master of his craft, he knows when and where to use it. The thing that excites him the most nowadays are different festivals that happen around the world, like a recent lantern festival he attended in Japan. He finds inspiration in the objects and props he sees and in how they become an integral part of a much a larger experience. “As an artist,” he explained, “you are often taught to make things in seclusion that are then put in a specific place for the initiated. How do you create something that is part of larger, enriching experience that affects people who aren’t necessarily seeking art out?” That is the question that drives Frelin to create beautiful works of art that can be experienced by everyone.

Oslo, Norway, the birthplace of the renowned Norwegian artist Edvard Munch, is now home to a stunning new waterfront museum that houses the world’s largest collection of Munch’s works. The 60m-high tower, designed by Spanish architect Juan Herreros of estudio Herreros, features 13 floors and 11 gallery spaces. This flexibility allows for a versatile lighting system that caters to the diverse needs of individual exhibits and spaces. The museum's design team, spearheaded by Oslo-based Zenisk, faced the task of ensuring visitors didn't feel a stark difference between natural and artificial lighting. They aimed for an environment where the artificial lighting remained unnoticeable, creating a space that felt natural and intuitive to navigate. Kristin Bredal, CEO and creative director of Zenisk, a pivotal figure in the lighting design, emphasized, "The objective was to have the artwork seem naturally illuminated. The museum's guiding principle was to prevent the exhibition halls from

designing lighting

appearing shadowy, where artworks stood out like isolated icons." Instead, the museum desired its halls to exude a sense of brightness and comfort. A significant concern was to retain the authenticity of the colors in Munch's masterpieces. Bredal added, "The essence was to accentuate the purity of colors in Munch's artworks." This necessitated an emphasis on superior light quality, accurate color rendering, and precise distribution and angle of lighting. Recognizing the importance of color rendition, Bredal remarked on the exceptional quality provided by ERCO, alongside other features like seamless light distribution and the ease of optics replacement.

The Innovative Lighting Approach at the Munch Museum Divided into two zones, static and dynamic, the static zone is devoid of daylight to protect the art. The dynamic zone is more open, with ample glazing to showcase views of Oslo. Visitors transition from areas of daylight into closed, artificially lit spaces, a design choice that required careful consideration to allow for daylight to low light transition necessary for the art. The lighting creates an illusion of natural illumination without visible focus, reflections or glare. The exhibition halls feel bright and comfortable, not dark with artworks appearing as icons.

Warm white 3000K, utilizing 2,500 DALI-controlled Parscan fittings from ERCO, was installed throughout the museum. The centerpiece of the exhibition is The Scream, one of Munch’s and the world’s most iconic works, described by American journalist/art critic Arthur Lubow as “the Mona Lisa for our times.” More accurately, three versions of the artwork that Munch created are featured, mounted in cabinets that are alternately open during the day due to their fragility and sensitivity to light exposure. The gallery housing these works is completely dark with black-painted cabinets. The collection is illuminated to just 2.32fc with precisely adapted framing using ERCO’s Eclipse spotlights. The effect is that the art seems to “emerge from the darkness.” The remainder of the exhibition is lighted so that this main work does not appear dim in comparison. Bequeathed to the Norwegian government by Munch upon his death in 1944, the collection includes more than 26,700 works, around 1,200 paintings and over 42,000 museum objects. The individuality of the collection, their visibility, the narratives in their curation, and how the room and organization of exhibits are perceived were all factors in the lighting design.

UP CLOSE WITH

Lee Brandt By SHIRLEY COYLE, LC

During year three of a five-year architectural engineering program at Penn State, someone passed Lee Brandt an issue of LD+A, the IES’s monthly magazine on lighting, design and application. “I thought, wow, this is perfect – this is what I wanted! I had wanted to be an architect, but this is where I could use my nerdy math/engineering brain and combine it with the art side!” Coming from just outside Philadelphia, Lee had two amazing summer internships with a small lighting design firm in Philadelphia, but she knew, even before becoming a lighting designer, that she wanted to move to New York City – “kismet for lighting design!”

the firm, Lee was given the chance to take over a large resort hotel project. “It was kind of a rite of passage project” over 4 years, finishing just as she gave birth to her first son.

After interviewing in NYC with almost every lighting design firm possible, Lee decided that HLB was the right fit and joined in 2000. “I kind of go by gut a bit – it felt right, and it definitely worked out!” Lee is now a Principal of HLB’s New York Office, these days combining her architectural lighting design work with a strategic role that focuses on employee growth across HLB’s eight locations. Active in both IES and IALD, Lee makes the time to contribute to the broader lighting community, serving on committees related to light pollution, sustainable design and energy codes.

Reflecting on what has made her successful in her lighting career, Lee offers a few things: “Staying curious and engaged, taking opportunities when they come. HLB was an amazingly supportive. When I became a Principal, HLB pushed me toward recruiting. They saw a natural talent there – I want people to be happy. I’m grateful that I had a firm and people with me that supported me, saw some natural talents and helped me fill in the rest. Keeping up is important – you can’t rest in this world. It’s changing so much; you have to stay on top of things.”

And how did the move to New York City go? “That was ones of the best part early on – it was so exciting to be in the city, the commuting – kind of Mary-Tyler-Moore type stuff!” Lee found it great coming into HLB and working with people with backgrounds in interiors and theatre, people having so much more experience than she had been exposed to in the more controlled university environment. Soon after joining HLB, Lee was tapped to use the thennew lighting design modelling software, Lightscape, for a Disney project – “It was pretty great, I felt useful early.” Lee’s technical skills brought a lot of work her way in computer modelling, especially sports facilities, and she remembers a fun challenge with a pool having issues with light levels impacted by obstructions. “The site was in Pennsylvania, near my parents’ home, so I went home, got my brother and Mom to come with me to help, and there I was in the water with a kickboard and my light meter in a plastic bag to keep it dry, taking measurements and calling out light levels for them to write down!” Lee also remarks on HLB being generous with opportunities; when someone left 80

Asked about her concerns over the current state of our lighting community, Lee says, “For me, it’s about feeding the machine - we need to get students exposed to lighting design and to find diverse educators to teach lighting design. So many of our amazing educators are going to retire soon, and I don’t know if we have a pipeline. We have to get the lighting industry known among a broader audience.”

Lee’s advice to those coming into the lighting community: Stay curious, ask questions. “I don’t think we’re an industry of wallflowers, but you have to find, within yourself, how to stay engaged and get yourself out there, find ways to connect and express yourself. There’s a definite professionalism needed: look people in the eye, communicate properly, both verbally and in writing. You don’t have to be a Type A or natural extrovert, but be authentic – and you need to advocate for yourself. It can be done quietly.” During Lee’s most recent couple of recruiting trips to schools, she found that many of the students wanted to be able to collaborate in person and were looking for roles where they would have the opportunity to work in-person with others. When Lee is not working on the many aspects of building HLB and the lighting community, you many find her at one of many sports events involving her teenaged sons. During rare downtime, perhaps she will be taking in some reality TV for a well-earned mental break, or digging into pop culture, especially movies. Lee’s family loves to travel – the most recent big trip to Ireland and London was a hit. Now, the planning starts for the next trip, with Paris heading the list of options! ■
