BENYA’S ART & SCIENCE Designers of outdoor lighting are either facing or will soon face limitations on their designs by a new generation of codes and standards associated with the Dark Sky movement. While outdoor lighting codes are not a totally new idea, 21st century standards such as the Model Lighting Ordinance (MLO) are designed to restrict design freedom relative to off-site impacts like light trespass and light emitted upward into the sky. And the message is getting out to regulators. Those who work in California face the state’s environmental code, CalGREEN and the Title 24 energy code that together limit commercial lighting very much like the MLO does, and the California Coastal Commission is especially concerned about any lighting along or near the coastline. Those who work in Florida know that lighting on or near many of its beaches is restricted to long wavelength, fully shielded luminaires, and not many of them. And those who work in Southern Arizona face stiff standards to help preserve the night sky for astronomy. Slowly, place by place, modern lighting codes are becoming part of our regulatory framework. To any lighting designer, this might seem unfair and severely limiting to artistic freedom. Several generations of inspired and award-winning designs might not ever be replicated, and in a number of cases, the original is being constrained to limited use or removed altogether. For example, the spectacular 2020 lighting of the Acropolis, winner of three [d]arc Awards, employs flood lighting techniques and high color temperature light sources that are frowned upon among dark sky advocates. The spectacular and iconic Twin Towers of Light in New York are limited to sporadic use because they cause migratory birds to get lost in the beams and fly in circles to their deaths, by the thousands. And, in major cities where upper-story penthouse living is a luxury, prominent LED building identification and product advertising signs are facing well-financed opponents in high stakes legal battles to either prevent the signs altogether or, at least, require significant dimming and late-night shut off.
The start of the Dark Skies movement can be traced to the predecessors and founders of the International Dark-Sky Association. IDA was founded in 1991 by Dr. David Crawford, an astronomer and recipient of the 2021 IES Medal, and Dr. Tim Hunter. Although heavily influenced by the impacts on astronomy by anthropogenic light at night (ALAN), IDA has somehow managed to take a broad view of the topic and early on, looked upon ALAN’s impacts on people, plants, and all other manner of living beings. Even before the “human centric lighting” era, IDA members and other scientists were studying the impacts (mostly negative) of ALAN with disturbing results. Thanks to Dr. Crawford and his unbeatable promoting skills, the IDA and IES collaborated in developing the MLO, including the lighting zones, TM-15-11 and the BUG system. Meanwhile, a pair of scientists from the University of Southern California, Dr. Travis Longcore and Catherine Rich, published Ecological Consequences of Artificial Night Lighting that discusses the impacts of light at night on a number of different species. Their work became an integral part of the Dark Skies movement. There are still challenges in bringing them together, but that’s Calling all lighting designers: We won the energy efficiency war, as lighting today uses 90% less energy than energy code compliant buildings in 1979. Now, we must turn our attention to reducing outdoor light pollution. This will be harder.
The MLO helped by providing professionals with guidance, and the USGBC helped by adding controlling light pollution as a point in LEED. But still, the three major decision makers for most lighting remain price, availability, and whether it will light the heck out of everything. Nasty, glaring 5000K LED floodlights and LED replacement lamps are leaping off the shelves of distributors and DIY stores and onto small commercial properties and private homes at an alarming rate, and ill-advised cities are installing 4000K LED streetlights. People tend to relate glare with safety and security. This awful trend breaks every one of the five principles, and it is out of control at the moment. Now along comes help from two influential organizations that I think can make a quantum difference. DesignLights Consortium® (DLC) has introduced LUNA, technical requirements that are “…intended to mitigate negative impacts of lighting at night by establishing system performance specifications and best practices.” It serves as a qualified products program similar to their energy efficiency programs, and I hope will be used by utilities and ESCOs to eliminate poor lighting practices in the retrofit and replacement lighting market. The other is the National Association of Innovative Lighting Distributors (NAILD), a national nonprofit trade association driving lighting innovation through networking and education. They believe that through proper training, the distributor’s employee “at the counter” will educate electricians and contractors as they sell them appropriate gear. They have embarked on a Dark Sky Training program for their members. I think this may be one of the best ideas yet, as a huge percentage of lighting “designs” are in fact the recommendations of a salesperson. Try to imagine a world without unshielded 5000K floodlights and wallpacks! Now if only the DIY stores and websites would stop selling high CCT LED products to consumers.

16 designing lighting what I think professional lighting designers should do. It has taken a decade since the MLO for the dark skies idea to even begin to mature. At first, there was an undercurrent of push-back because outdoor lighting was competing with the energy efficiency improvements of using LED luminaires. Early LEDs were most efficient at high color temperatures, and this gave rise to 4000K and 5000K lighting outdoors that still persists. But major improvements in 3000K, 2700K and now 2200K have occurred, and the efficacy of these sources is at least 75% of that attainable with the glaringly bright high CCT lights. This became critically important in 2015 when the American Medical Association, frustrated with a lack of progress and the amount of disinformation, took a stand in declaring all outdoor lighting should be 3000K and less. I remain frustrated, however, as far too many people confuse glare with good vision and think 4000K (or higher) is good because its glaring. It is not, with a few notable exceptions. For instance, the US Tennis Association (USTA) requires 4000K or higher for competitive tennis court lighting. I still wonder how they played tennis under incandescent lighting, but honestly, I think it has more to do with television cameras than tennis. That said, I am encouraged by the increasing stream of publicity and several important initiatives. In 2021, the IES and IDA announced a strategic collaboration to address “the global issue of light pollution that negatively affects our environment and the human condition.” The first joint action was to create “Five Principles for Responsible Outdoor Lighting,” that include 1. All lighting should have a clear purpose 2. Light should be directed only where needed 3. Light should be no brighter than necessary 4. Light should be on only when it is useful 5. Use warmer colored lights where possible
The big question that the lighting industry should ask itself is whether we want to make a bigger commitment and get better organized to address how our work ends up regulated. Like many things in our industry, we rely too much on personal initiatives until the government gets involved. That’s how energy codes went, and how, until recently, we, the IES, and the lighting industry developed the lighting energy codes as professionals and experts. Unfortunately, once governments get involved, the industry as a whole loses control as lobbyists and influencers take over and the probability of a high-quality and appropriate outcome diminishes. We are at an inflection point in the challenge to achieve and maintain dark skies. I hope we can rise to the occasion and, like we did with energy codes, encourage better applications, design skills and our own standards well enough to achieve significantly darker skies without excessive government blundering. ■
BENYA’S ART & SCIENCE
Finally, dark sky concerns are not limited to lighting, either. A whole new generation of billboards and signs using LED pixels instead of floodlights is rapidly replacing old fashioned billboards, offering constantly changing and very bright images. In response, IES RP-39-19 dramatically reduces recommended sign luminance according to lighting zone, which is a start. But, it does not address the ability to “aim” the light of a modern LED billboard at an intended audience while not lighting neighbors’ homes and yards and seems based on obsolete technology and techniques. Now that LED billboards can be aimed and dimmed and their emitted spectrum controlled according to time, I foresee a revolution in this already evolving marketplace that will also require visionary leadership to develop appropriate standards based on new capabilities.

The survival of virtually any organism depends on a complex system of internally generated, repeating physiological processes called circadian rhythms. In humans, these rhythms cycle at a period of roughly (but not exactly) 24 hours and include processes such as sleeping and waking, hormone production (e.g., melatonin and cortisol), core body temperature, and digestion, just to name a few. The pattern of light and dark on the retina is the principal environmental cue for synchronizing human circadian rhythms to our local position on Earth, ensuring our body does the right things at the right times of day and night. Disruption of these rhythms by light at night and insufficient daytime light exposures has been linked to poor sleep and a host of health and behavioral problems.

Lighting for TransplantEntrainmentCircadianinMyelomaPatients
MARIANA G. FIGUEIRO, PHDBy Professor and Director, Light and Health Research Center
Patients with multiple myeloma—a cancer that forms in plasma cells and accumulates in bone marrow, crowding out healthy blood cells that fight infection—spend 2–3 weeks in hospital rooms while undergoing autologous stem cell transplantation to combat the disease. The healthcare environment’s typically low daytime light levels and frequent exposures to light at night can lead to circadian disruption and compromise patients’ recovery. To address these concerns, the Light and Health Research Center (LHRC) and collaborators (William Redd and Heiðdís Valdimarsdottir), under funding from the National Cancer Institute, conducted peerreviewed pilot research to determine whether administering circadian-effective light early in the day could maintain multiple myeloma patients’ alignment with the day-night cycle, as indicated by high nighttime melatonin levels and good sleep quality.
18 designing lighting
Fifty-five patients were randomly assigned to two lighting conditions, providing either circadian-effective light (n=27) or circadian-ineffective light (n=28) in their hospital rooms between 7 and 10 a.m. each day. The circadian-effective light treatment was specified following the circadian stimulus (CS) model developed by LHRC researchers over the past 20 years.1-4 For this study, the circadian effective light was specified to a criterion CS value of AND HEALTH
The Lighting Acuity Brands developed the study’s custom-made freestanding 3000K luminaires (Figure 1), which were used to deliver either the circadian-effective bright white light (BWL) condition (ranging between 1000 lx and 1300 lx, CS = 0.3) or the circadian-ineffective dim white light (DWL) condition (about 90 lx, CS = 0.1), measured at the patient beds’ pillow surface. The CCT of 3000K was chosen to make the rooms’ appearance less institutional and more homelike, and the ambient lighting form factor was selected over light boxes to reduce patients’ compliance burden. CS levels were continuously monitored on the wall behind each bed, on each luminaire, and at each patients’ chest level using three separate Daysimeters (calibrated light meters developed by LHRC researchers8, 9). The measurements showed that patients in the BWL condition received significantly (p < 0.001) higher CS values than those in the DWL condition. Study Results
Patients’ sleep time in the BWL condition steadily improved over the course of the study, whereas those in the DWL condition slept for shorter durations by the study’s end compared to the beginning (Figure 2A). Depression scores, obtained in an earlier, peer-reviewed iteration of this study10 involving fewer patients (BWL = 23 patients, DWL = 21 patients), but retaining the strong statistical effect, were also significantly better among those experiencing the BWL condition compared to those in the DWL condition (Figure 2B).
Sleep quality and depression scores were assessed prior to hospitalization, on post-transplant days two and seven, and on post-engraftment day three (i.e., after the body accepts the transplanted stem cells, typically the day before discharge from the hospital).
Figure 2. (A) Mean sleep time (in minutes) throughout the study’s four assessment days for the two light conditions. Although not statistically significant, sleep duration at the end of hospitalization increased by over 50 minutes in the BWL group compared to the DWL group. (B) Depression (CES‐D) scores throughout the study’s four assessment days for the two light conditions. Mean depressive symptoms increased for both groups, but only the mean score for patients in the DWL condition met the criteria for clinically significant depression. The data presented in panel B were reported in Valdimarsdottir et al.10
Nighttime melatonin levels were assessed prior to hospitalization and post engraftment. Sleep quality was assessed using wrist-worn devices that measure activity and light. Depression scores were assessed using the Center for Epidemiological Studies Depression Scale (CES-D). Nighttime melatonin levels were assessed via the measured concentrations of creatinine-corrected urinary melatonin-sulfate (6-sulfatoxymelatonin, or 6-SMT) in the patients’ first morning void urine samples.
Patients’ nighttime melatonin levels in the DWL condition declined compared to their pre-hospitalization levels. The levels among patients in the BWL condition remained almost constant, suggesting that their circadian rhythms remained aligned following their admission and treatment (Figure 3).

Despite these limitations, our findings demonstrate that this easy-to-deliver, low-cost intervention nonetheless improves sleep quality during hospitalization for autologous stem cell transplantation patients.
Figure 3. The mean difference between pre-hospitalization and post-treatment nighttime melatonin levels for the two conditions (6-SMT per ng/ng creatinine). The positive difference means that melatonin levels after hospitalization were significantly decreased in the patients receiving DWL, while they remained stable in the patients that received BWL, reinforcing the suggestion that circadian alignment was better maintained in patients who experienced the BWL condition.

20 designing lighting rooms can maintain patients’ circadian alignment, which leads to better sleep. Given that good sleep has been linked to a series of health benefits, this approach represents an important first step for improving health in hospitalized patients, especially among those in longer term recovery from procedures like autologous stem cell transplantation. These results should be interpreted in the context of some important limitations, the principal ones being the study’s preliminary nature and small sample size. Also, because the results do not include post-hospitalization assessments, it cannot be said whether the circadian-effective light delivered during hospitalization affected primary disease outcomes during the extended post-transplant period. We have just been awarded a large grant from the National Cancer Institute to perform, together with Memorial Sloan Kettering Cancer Center in NYC, a clinical trial that will extend these preliminary results while also measuring immune function biomarkers and patients’ symptom burden. Despite these limitations, our findings demonstrate that this easy-to-deliver, lowcost intervention nonetheless improves sleep quality during hospitalization for autologous stem cell transplantation Inpatients.ournext column, we will outline possible design strategies for implementing a comprehensive lighting regime in hospital rooms to promote patient recovery and general well-being. ■

Randy Burkett and Lisa Reed had been collaborating on key projects for many years since that chance encounter in 1993. Lisa was coming in to help on key projects and working together led to the merger. Envision Lighting Design was a growing firm. Merging with Randy met certain of Lisa’s goals, and it put the two of them in a position to solicit new and exciting clients that neither had access to before. Lisa says of her mentor
When Randy Burkett had a key employee leave his company, what appeared at first to be bad news became fuel for transformation. As an alternative to finding senior lighting designers to fill in, he sought another lighting business owner whose collaboration might become long-term.
More recently, in 1993, a Saint Louis lighting luminary critiqued the senior project of an architectural engineering student. Little did they realize that this chance meeting would blossom into future collaborations and culminate in the merger of their lighting design firms. Randy Burkett Lighting Design and Envision Lighting Design have combined their considerable forces to become Reed Burkett Lighting Design.
23designing lighting Saint Louis has long been associated with discovery, innovation, and collaboration. Just over 200 years ago this “Gateway to the West” served as the launchpad for a legendary expedition, and 100 years back a rising jazz star described its riverboats as “floating conservatories.”
THE BUSINESS OF LIGHTING DESIGN™
And just who were those explorers venturing forth over 200 years ago from Saint Louis to light the path of westward expansion? You may have guessed it already: the legendary Lewis and Clark. And that future star plying the riverboat trade off the banks of Saint Louis? None other than the great Louis Armstrong. We look forward to seeing where the expedition takes Reed Burkett Lighting Design: perhaps to a place where light becomes music distilled. Saint Louis continues to inspire. ■
Before the merger, Lisa’s firm was operating from a coworking space and searching for something more permanent. As fate would have it, Randy had some open office space and offered it well before they ever knew they would merge. The two of them value the office culture and the physical office experience and have hybrid set-ups and have worked to offer their employees flexibility between office and remote working.
When looking at trends, Randy says that, currently, outdoor lighting is over 50% of his business, but 20 years ago outdoor lighting was less than 20%. He designs lighting for many large-scale urban parks, sculpture gardens, and more. He believes that the current generation is excited about living in cities and making them livable, so the lighting is changing. Lisa on the other hand often works in healthcare, higher education, and commercial offices. Lisa and Randy had strengths in different markets, opening up new project opportunities for both of them. Randy explained that a lot of his time was consumed by administrative work and that he wanted to get back to lighting design. He said, “The time I do have left in lighting, I want to spend designing, not administration.” His passion for design is best demonstrated in the work he produces.
He craves spending more time with clients and working on passion project. Lisa says that before the merger, she spent a lot of time doing billing and accounting but is excited to have a team of people who can take on office tasks, freeing her to do more design. When it comes to the current workload, the duo is plenty busy.
Randy expresses that one of the biggest trials he used to face was convincing a client that lighting design is a legitimate discipline. Now it’s more likely to be seen as vital to the user, and most don’t need to be convinced that a lighting designer is essential.

Turato wanted the lighting to evoke emotion and deeply connect with the architecture of the hotel. With Zumtobel on board, he easily integrated black-coated controllable lighting systems. To create an atmosphere of warmth and welcome, 3000K light fixtures are utilized throughout. Downlights are used to maintain energy efficiency, and in keeping with Turato’s sophisticated design, light sources are almost invisible.
In the hallways, lights are aimed to bring attention to specific design elements. General lighting contributes to elevate the surroundings. Vintage light fixtures are used in the restaurant, creating islands of light.

The tourism industry in Hawaii was completely shut down, therefore construction and other projects were pushed forward quickly. Issued in 2020, Kelly received seven scopes for the property, and they are being completed one-by-one. As of this writing, the two most recent are the lounge and the breakfast dining area. A grab-and-go snack area is in the works.
A visit to the island of Maui must include a stop at the Grand Wailea, a Waldorf Astoria Resort. This getaway is an oceanfront paradise offering posh accommodations, award-winning restaurants, Hawaii's largest art collection and much more. Kelly Hannon of Focus Lighting recently completed and commissioned its spectacular lighting Workingdesign.
from my temporary remote office a few miles away, I met Kelly at the site for a tour. (OK, I was really on vacation, but I did answer some emails.) As the Waldorf began the considerable remodeling job, they hired Tihany Design for interior design. Focus Lighting, founded by Paul Gregory, has closely collaborated with Tihany for 20+ years and has done much design work on the islands, including the nearby Andaz Maui. In addition, Kelly had been involved in other Waldorf properties, such as the ongoing NYC renovations, and quickly jumped on board to redesign these spaces.

The recessed fixtures from LF Illuminations, valuDIM luminaires, are aimed at walkways and bars. The valuDIM is adjustable with a round, flat minimal trim. It uses a standard driver which works with either 0-10v or forward or reverse phase dimmers and achieves minimum visible light output of less than 2%.
It was a joy to tour the space with Kelly, where she showed off her unique and modern design, and how first-class lighting dramatically elevated the Grand Wailea resort.
As a special treat, Kelly took us to their current work-in-progress, Loulu. This is a grab-and-go cafe with new finishes, a new configuration, new lights, and new fans. This retail area includes Amerlux Hornet recessed adjustable accents and wet location accents over food prep surfaces.

Moving away from admiring the beautiful work, we talked about the business of lighting design. Focus frequently works with repeat customers and collaborators, which is how this project came about. While the scope varies by client’s needs, it generally covers all phases of design including schematic design, design development, and construction documentation. It also covers construction administration which entails extensive coordination on shop drawings and submittals as well as site visits. The process culminates in the commissioning trip to apply the finishing touches and deliver the full vision to the client.

With Billings being a melting pot of new and current residents, the city craved a world-class theater. The Alberta Bair Theater is a newly expanded and renovated 90-year-old Fox Theater originally completed in 1931 once featuring vaudeville acts.

We discussed the rapid growth of Billing's population, and Madeline explained that during the pandemic, many people moved here buying homes site-unseen. Tim added, “A buddy of mine is a realtor and he personally sold 15 houses during the height of the pandemic, all through FaceTime.” This explains why my 3.5-star hotel was $350.

On my way to the ranch, I stopped in Billings where I met Madeline Randolfi, a commercial interior designer with Cushing Terrell, and Tim Kiser, the Technical Director of Alberta Bair Theater.
The original Fox Theater was built on land owned, farmed, and ranched by Alberta Bair’s family. Before Alberta's passing, she donated the land for the arts. During the Great Recession, in order to fulfill Alberta's wishes, the city ensured that the theater remained.
The installation is beautiful as these glass luminaires cascade from above. Vertical stems pass through the light fixture to create visual continuity accentuated by the glowing glass disc to create a striking effect. At 3000K the luminaire blends well with the aesthetic of the building and its history. Besides looking beautiful from inside, seeing the lights through windows from across the street, is stunning. The chandelier is art in its own right. As the electrical engineer on the project, Michael was responsible for the lighting controls. “We used the Acuity nLight system. The fixtures are individually controlled by 0-10v power packs that are usually energized to 100% when the building is occupied," he
The space presented a unique opportunity because of the sheer size of the two-story expanded lobby. Madeline described the design process stating, “Michael and I knew that we needed a luminaire with a large presence. It was difficult to find a fixture with enough volume to fill the space, and that also maintained the elegance of the remodel.”
Theexplained.theater seats just under 1,400 people, but with the 4,800 square foot lobby, the theater can now accommodate more pre or post show events. The expansion provides the residents of Billings and the surrounding areas an opportunity to mingle inside of the theater with a beverage in hand, he explained. Besides being a venue for the performing arts, the Alberta Bair Theater often partners with local schools to host educational programming. The nonprofit theater not only serves as an auditorium but also acts as a locale for children to foster their creativity.
Madeline explained that the two-year remodel was funded mostly by private donations and grants. The theater has the potential to bring a large amount of business to the city thus to the local economy.
Madeline recalled that the original concept was to have multiple single decorative pendants that would have filled the two-story space. Then during the early stages of the project, the design team introduced the idea of one large pendant. After working through multiple iterations, the design team had exhausted all solutions to find the perfect fixture.
If you ever find yourself in Montana, don’t hesitate to step into the Alberta Bair Theater in the center of downtown Billings. White you're at it, you may as well enjoy a show.
The Eureka rep, Frank Dugas, came by at a very opportune time. Frank introduced Madeline and Michael to the Droplet Celeste - a clean minimalist pendant featuring elegant artisanal casted glass discs. When Madeline saw installation images of the luminaire, she was impressed by its volume to appropriately fill a space. It was at that moment that the design team knew they found their answer. She explained, “There’s beauty in these fixtures; they have the appropriate scale and length while maintaining the desired aesthetic.”
36 designing lighting the potential for three to four-foot snow drifts on the rooftop during the winter and the additional weight from stage lighting and rigging, the existing structure was strengthened. Tim reinforced that the additional support provides the ability to host larger productions.
Madeline and Michael Gieser, a lighting designer with Cushing Terrell, completed the construction documents in 2019.
The design team knew that the Alberta Bair Theater board members would equally love the Droplet Celeste. As difficult as it can be for board members to agree on a decision, they did not hesitate as these multiple pendants added much more interest than one large fixture.
The luminaires were ordered just before COVID impacted the construction industry and disrupting the supply chain. With Eureka's pre-made plug-and-play packages, the design team found it easy to adjust the number of units to customize the luminaire to their liking.

The new L-Prize seeks innovative luminaires and connected systems that demonstrate exceptional achievement across six areas.
Fast-forward to 2021 by which time 90 lm/W was no longer a stretch goal for LED lighting products, but significant headroom for performance and application
More than a decade ago, the Department of Energy (DOE) staged a technology competition that challenged the lighting industry to develop high-performance, energy-saving LED replacements for conventional 60-watt, screw-in light bulbs. The DOE dubbed its effort the “L-Prize,” which two years later resulted in the Philips 10-watt, A-19 LED replacement lamp that helped revolutionize lighting. The technology innovations in that L-Prize winner—more efficacious LED chips, electronic miniaturization, better heat transfer, improved optics, and remote phosphors—found their way into later generations of Philips LED products. At the time, progress on the luminous efficacy of LEDs was a big focus, and the L-Prize winner showed that 90 lumens per Watt (lm/W) efficacy with high color rendering and very long life was possible, raising the bar for the entire lighting industry. Just in the United States alone, today’s LED replacement lamps are helping to avoid an estimated 98 million metric tons of carbon emissions each year.

39designing lighting improvement remained. The DOE developed an ambitious follow-on L-Prize competition specifically targeting breakthroughs in lighting for commercial buildings, a sector that accounts for 36% of national lighting energy use. Commercial and institutional buildings often have long operating hours and need relatively high-output lighting for general illumination supporting workplace safety and functionality. These factors point to potential for energy savings and quality improvements in buildings traditionally lit by linear fluorescent tubes. The new L-Prize calls for luminaires and control systems that can capture additional benefits of LED lighting in terms of energy performance, lighting quality, advanced connected lighting control, and life cycle sustainability. The competition encourages and rewards technical innovation and attention to diversity, equity and inclusion (DEI) in the design, manufacturing, and application of LED-based lighting systems. We are rolling out the L-Prize in three phases, with the Concept Phase now complete and four winners of $20,000 each announced by Energy Secretary Jennifer Granholm in January 2022. An L-Prize myth holds that only these four winners can advance to the Prototype Phase, but that’s not correct. Each phase of this L-Prize is effectively a separate competition. Everyone is welcome to enter whether you competed in the prior phase or not and we’re looking for new participants to enter each phase. Our vision for what lighting can accomplish features significant energy savings, excellent lighting quality, and functionality that improves indoor environments for people. The L-Prize is the chance for lighting innovators to be recognized for creativity and engineering in luminaires and systems that break through traditional limitations and trade-offs. The rewards are significant, with a prize pool that totals $12.2 million across the Concept, Prototype, and Manufacturing and Installation (M&I) phases. The Prototype Phase, which officially opened on June 30, 2022, features two separate tracks: one for luminaires and one for connected systems, offering

multiple pathways to participate, whether you are a small independent luminaire manufacturer or a large luminaires and controls manufacturer. Over the course of the next year, entrants will develop physical prototypes for one or both tracks that demonstrate their innovative approaches. Submissions are due May 1, 2023, when they will be evaluated by an Expert Review Panel consisting of eight independent lighting industry thought leaders. We will award and recognize up to six winners of this phase to share a prize pool of $2 million. The final M&I Phase increases the stakes, with a prize pool of $10 million to be split among up to four competitors. This final phase carries through all the innovation opportunities of the Prototype Phase, and then adds in requirements for commercial availability and installation(s), and incentivizes U.S. content and manufacturing. We anticipate teams may be needed for this final phase, so we’ve opened up a Teaming List. It’s a way for manufacturing partners, materials or component suppliers, end-user installation host sites, utilities, energy service companies, and others to express their interest to collaborate with or support an L-Prize team in pursuit of the $10 million prize pool. We’re proud of the fact that this L-Prize awards bonus points for exceeding minimum technical requirements in certain categories. Bonus points in the area of product life cycle reward sustainable and environmentally friendly designs. Bonus points in technical innovation recognize designs that are easy to use or cost effective. Bonus points for DEI acknowledge diversity within the participating teams and in the communities that will benefit from resulting innovations, including communities that have been historically disadvantaged. LED lighting has evolved from simply imitating previous lighting technologies to the still nascent but real potential to better manage lighting energy use, integrate with other building systems, streamline maintenance and operations, and even respond to electric grid signals, increasing the value and resiliency of buildings. We on the L-Prize team embrace this shift and seek to unlock the full potential to combine high luminaire efficacy with exceptional lighting quality, data-driven control and functionality, and sustainable design and construction for the future of illumination in commercial and institutional buildings.

According to a 2020 report by the DesignLights Consortium® (DLC) and Northwest Energy Efficiency Alliance (NEEA), average energy savings can exceed 60% with this approach. This article defines and describes LLLC technology, system types, advantages and disadvantages, and what’s familiar and distinctive in regards to design and installation.
Clever: Clever LLLC systems satisfy basic DLC networked lighting controls requirements for dimming, occupancy sensing, daylight response, and high-end trim.
Control functionality: This element may be an integral part of the LED driver(s) or a separate device that sends dimming signals to the driver(s). Wireless or wired connectivity: The luminaires may be wired via low-voltage, low-voltage digital, or power over Ethernet (PoE). Wireless connectivity is achieved via an onboard radio transmitter and receiver connecting the luminaire to an LLLC network using an accepted protocol. Depending on the system, a fourth element, centralized network hardware and software, may be added as a layer atop the LLLC luminaires. Centralized hardware may include hubs or gateways, which serve as central collection points for managing the flow of data in a network. Data may be stored to a central server or the Cloud for retrieval and analysis.
In January 2021, the NEEA published the 2020 Luminaire Level Lighting Controls Incremental Cost Study. In their report, the NEEA categorized LLLC as Clever, Smart, or Hybrid, producing informal definitions that may be helpful to visualize the offering.
Craig DiLouie is education director for the Lighting Controls Association, a council of the National Electrical Manufacturers Association that educates the public about lighting control technology and application (www.LightingControlsAssociation.org).

Luminaire-level lighting controls (LLLC) are a subset of lighting controls in which control functions are integrated into luminaires, allowing individual luminaire control. This approach is highly flexible and responsive, and advanced options additionally offer connectivity to produce data-related benefits.
The LLLC Approach Definitions for LLLC vary, but the common idea is sensors and control functionality being embedded into luminaires. Today, there is a wide variety of control systems designed around the approach to maximize energy savings while addressing specific user needs. In the majority of LLLC systems, the three major control elements installed in the luminaire or luminaire retrofit kit are: Sensors: The sensors may include an occupancy sensor, daylight sensor, or a multipurpose unit combining the two.

Advantages and disadvantages
Energy Savings
The highest-performing LLLC had additional features such as scheduling, task tuning, plug load control, and energy monitoring. Meanwhile, the installed cost for the LLLC was roughly one-third to one-half of the NLC redesign option.
Owner: The owner gains energy savings, the ability to finetune and reconfigure the system in the future, and potentially advanced functionality/data.
The advantages often outweigh the disadvantages. Initial costs can be offset through simplified hardware installations and value-added functionality. Additionally, careful system selection can anticipate other concerns and result in a solution that is well-tailored to occupant needs.
Contractor: For the electrical contractor, it can ensure control compatibility, simplify wiring, and reduce time and risk by eliminating installation of control devices.
Distributor: For the electrical distributor, it offers an energysaving solution that can streamline product schedules for lighting projects.
Designer: For the designer, LLLC offers flexibility by reducing the need to predetermine switch leg wiring/zones.
In this application, the LLLC options generated 50-74% energy savings for the controls alone (not including the LED upgrade), while the NLC solution demonstrated 67% savings.
43designing lighting GET CONTROL! other (e.g., occupancy) data that can be used for Internet of Things (IoT) applications such as space utilization.
LLLC offers several advantages as an NLC option. By embedding sensors and control functionality into each luminaire, control is overall highly granular and responsive, which can increase energy savings.
Applications The Department of Energy estimated the installed base of networked luminaires will grow from less than 1% currently to about one-third of all lighting in commercial buildings by 2035. Due to its advantages, LLLC is positioned to play a strong role in this growth. Currently, LLLC is typically installed in office buildings and schools but is also deployed in high-bay, parking garage, gas station, library, and other applications.
Occupants: Users interact with a lighting system that satisfies energy codes while offering personalization potential. The primary inhibitors, meanwhile, are the luminaires’ higher base cost, higher complexity of the project, insufficient value or savings for a given project, and uncertain owner interest in advanced functionality. In addition, occupants and designers may have objections to systems that permit every luminaire to operate independently as opposed to in a uniform and coordinated manner.
Hybrid: Clever-Smart hybrid LLLC systems are Clever systems with energy monitoring capabilities but not advanced data collection. Control strategies The foundational LLLC layer places key elements of an autonomous yet groupable control system within each luminaire with a versatile range of inputs and outputs. Inputs include the occupancy sensor, daylight sensor, manual controls, and any programming. The control functionality decides whether and how to change the lighting based on the commissioning and desired sequence of operations. Depending on the system, outputs may include scheduling, switching, dimming, color tuning, and data. These combinations of inputs and outputs enact a range of popular control strategies including occupancy/vacancy sensing, daylight harvesting, scheduling, high-end trim (institutional task tuning), manual control/override, color tuning, and more. With an LLLC-enabled luminaire, we have a single lighting point capable of independently enacting one or more popular control strategies. When networked, the luminaires can participate in multiple, layered strategies that can be modified or custom programmed as needed, using individual luminaires as building blocks. This allows the control solution to be closely adapted to the application so as to maximize energy savings while ensuring occupant satisfaction. For more advanced systems with centralized connectivity, additional control strategies are available along with useful analytics. This is an area where certain functionalities have become common, while others are still evolving as technology advances. For example, additional control strategies such as HVAC room temperature, shading, and plug load control can be incorporated. Luminaires can also integrate other sensors, such as air temperature and humidity sensors and lowresolution infrared cameras. Fine-grained occupancy and other data from highly distributed sensors can be captured for purposes such as space optimization using the manufacturer’s software. Sensor data may also be fed to third-party, and in some cases custom, apps. If paired with Bluetooth or Wi-Fi connections, operators may gain the additional ability to enact asset tracking and contact tracing.
In August 2020, the NEEA published a study seeking to compare one-for-one LLLC retrofits with a comprehensive networked lighting controls (NLC) redesign. This study found that a one-for-one LLLC upgrade produced comparable energy savings and lighting quality as an NLC redesign at a competitive cost in a retrofit in a prototypical open office, an application well suited to LLLC.

Codes and rebates
While not mentioning LLLC directly, the upcoming 2022 version of ANSI/ASHRAE/IES 90.1 and the 2022 version of California Title 24, Part 6, effective in 2023, contain similar requirements for limiting the zone size of occupancy sensing in open offices, which provides opportunities for LLLC systems. Additionally, starting with the 2016 version, the ANSI/ ASHRAE/IES 90.1 energy standard allowed open office lighting to automatically turn on to more than 50% of power as long as the control zone is no larger than 600 sq.ft., which can make LLLC an attractive consideration.
The 2018 and 2021 versions of the International Energy Conservation Code (IECC) specifically mention LLLC in Section C405.2. This section identifies two paths for compliance with the code’s automatic shutoff, light reduction controls, and daylight response requirements—one based on traditional control devices and the other on LLLC. In open offices, where IECC requires occupancy sensing with control zoning limited to a maximum of 600 sq.ft., LLLC can simplify installation.
Rebates: A majority of commercial lighting rebate programs incentivize installation of energy-saving lighting controls. Standard rebates incentivize devices such as luminaireintegrated occupancy sensors and daylight dimming systems, for which LLLC systems will often qualify.
Generally, two types of applications are most suitable for LLLC strategies. The first is situations where both luminairespecific granular control of luminaires and coordinated zonal control is beneficial. Examples include open office coordination of occupancy zones, space requirements, and daylighting zones. The other is where the use of the granular data from advanced LLLC systems can contribute to space optimization and facilities management. For example, occupancy sensors on every luminaire, combined with detailed building drawings, could be extrapolated into occupant traffic patterns.
In addition, rebate programs that incentivize advanced lighting controls may align with LLLC to allow access to these more comprehensive opportunities. According to the rebate fulfillment firm BriteSwitch, more than one-fourth of rebate Image courtesy of Cooper Lighting Solutions.
LLLC as NLC Option NLC systems have a well-documented place in buildings as an important tool in addressing the energy efficiency of buildings. LLLC offers an NLC deployment option that places sensors and control functionality within the luminaire, creating a strong value proposition in certain common Forapplications.projectswith a need to manage overlapping complexity, desire for simplified onsite wiring, or granular access of data as part of a more comprehensive solution, LLLC systems should be considered. ■
In particular, when luminaires with pre-installed wireless LLLC are deployed on a project, installation can be greatly simplified. Additionally, sensors, controllers, and drivers are pre-tested as compatible. Depending on the type of LLLC and the needs of the project, there can be fewer requirements to mount discrete sensors (or perhaps no need for discrete sensors), and, for advanced LLLC systems, the amount of supporting hardware is likely reduced. Basic LLLC systems provide further potential benefit during installation because of the lack of supporting hardware, except for switches, in many cases. If it is a wireless solution, no control wiring is required. This can be particularly advantageous in a lighting upgrade project in an existing building, where utility rebates coincidentally may be available to reduce cost.
Some LLLC solutions feature all sensors and control functionality pre-installed in the luminaire by a single manufacturer, while others are available as discrete devices that can be added to luminaires in the field.
Configuration of LLLC systems is often through software accessible via a mobile app (or web browser for centralized systems). For centralized systems, the software is more sophisticated and enables facility operators to organize and program the network and also view the data in a useful presentation format.
Contractors interested in LLLC should familiarize themselves with the technology, particularly the principles of wireless communication, and specific products, which can vary in approach to setup and programming.
45designing lighting programs now separately incentivize installation of NLCs with prescriptive rebates. A majority of these programs qualify products based on listing in the DLC’s NLC Qualified Products List, which in 2022 has been transitioning to the Version 5.0 Technical Requirements. These technical requirements combine required and reported system capabilities, of which LLLC is a reported capability.
Despite potentially simpler installation of an integrated lighting and control system, increased labor should be expected for configuring and commissioning all of the sensors, manual controls, networking/communications between the devices, and additional components such as gateways and central controllers that may be needed depending on the LLLC type and project expectations. Additionally, some coordination with the owner’s IT department may be needed.
Designing with LLLC As a lighting solution of luminaires, an LLLC system is designed similarly to a standard system. Overall, the lighting must satisfy the owner requirements and the design intent. Attention to detail, however, must be given to aligning task areas and dedicated luminaires. As a controls solution, an LLLC system can simplify energy code compliance, particularly in complex spaces such as open offices with granular requirements.controlIfthat is the sole goal, a basic (NEEA “Clever”) LLLC system may be appropriate and achieved with relative ease. With more advanced (NEEA “Smart”) LLLC systems, the control solution may be programmable from a central point, with energy, occupancy, and other data collection. Design flexibility is gained in control zoning. The designer should familiarize themselves with integration and data capabilities for various systems. The designer should also note that the installation of a network may require owner IT buy-in and Ifinvolvement.requiredby the advanced LLLC system, the designer may need to incorporate the networking hardware (hub, gateway, server) and software into the project deliverables. Some applications can be served by wireless networking, wired networking, or a hybrid wired-wireless solution. The designer must also decide how programming and data will be accessed—web browser, mobile app—and who will be allowed to access it. Depending on the product capabilities and specific configuration ordered, some LLLC systems can be configured for different control objectives. For example, the designer could zone the direct (task) component of direct/indirect luminaires to be individually controlled but the indirect (ambient) component to be controlled as a group. Or, a row of luminaires might operate independently for occupancy sensing but be assigned to a group for daylight response. For best results, the designer should produce a clear written controls narrative along with a detailed sequence of operations. Installing LLLC

Designing premium spaces for sporting arenas is no easy feat—just consider the scale alone. Interior designers and lighting professionals have numerous elements to consider for embarking on any project of this size. Now think about the best way to light each individual premium area within that space in a way that makes them enticing and unique. That was the challenge presented to the creatives at Flos Bespoke and New York City–based interior design firm Goodrich for the UBS Arena at Belmont Park, the new home of the legendary NY Islanders. For more than a century, this historic park has hosted discerning guests for countless entertainment and sports events, but the time had come to take the hospitality aspect to a whole new level. By elevating the surroundings and visitor experience, the team at Goodrich worked with Flos Bespoke on custom lighting to define the spaces, create atmosphere, and transform the arena’s larger space and terrace into a series of intimate moments. The result is 100-plus custom fixtures ranging in scale and size, including: 5 globe cantilever sconces and an array of 26 Paoloni

Of course, this isn’t the first time the team at Flos Bespoke had worked on large sporting arenas, so that expertise definitely came in handy. “By the time the UBS Arena opportunity came to us, we had already had the experience of working on custom lighting for other sporting arenas of this size: specifically, the Barclay Center concourse [located in Brooklyn, NY] and the New Balance Sports Center in Boston, MA,” notes Coll. “The intention behind the lighting design was to bring a level of visual comfort and composition to each area—not just the VIP areas. While fans visiting these areas might understandably have their focus on grabbing some refreshments during the interval, or on their team’s performance, we do like to think our fixtures have added to their Inexperience!”termsofseeking inspiration and innovation in design and lighting today, Fisher doesn’t hold back on what he sees of great influence and importance. “Keeping your inspiration unique and fresh is a constant challenge in an era when the internet pulls us all toward the same trends. Our designers turn to books to search forgotten or underappreciated design movements from the last century, bringing fresh perspectives and ways of thinking to our work,” reveals Fischer. “Matthew Goodrich, our principal and founder, is particularly knowledgeable about design history and always brings fresh inspiration and design philosophies that just cannot be found scrolling through social media. Many intelligent thinkers have spent their careers considering design and how it relates to the human social experience. As young designers, we do ourselves a disservice if we don’t study their work so we can stand on the shoulders of giants.”Giada Paoloni Credit Giada Paoloni
While collaborating on a project for a venue of this size presents several challenges, the teams at Flos Bespoke and Goodrich proved to be a seamless partnership throughout the production process. “Working together with Goodrich on the initial design and approval phase of this project was condensed to just six weeks. The resulting production process of the custom fixtures took place over the course of 20 weeks and was timed for delivery to coincide with the arena’s lowuse period during their off-season,” explains Coll. “Our engineering team rose to the challenge of producing 10 unique custom assemblies simultaneously, and our main design objective was to ensure that all the pieces should have a uniform glow— without any visibility or glare from the LED source.”

The design vocabulary was inspired by classic New York venues such as the Bemelmans Bar, King Cole Bar, and Sardi’s—anchoring the experience in the history of the city.”

and Architectural Design
Genetic algorithms perform the same operations on the population of possible targets, with only those that better fit the solution surviving. Like other computational systems inspired by natural systems, genetic algorithms have been used in two ways: as techniques to solve technological problems and as simplified scientific models that can answer questions about nature. These algorithms are widely used because they yield accurate results and have fast processing times in many applications such as Photo Credit: Adobe Stock - Tierney
JUAN DAVILABy GENETIC ALGORITHMS: OPTIMIZING LIGHTING
52 designing lighting
Genetic algorithms were invented by John Holland in the 1960s, and since then, they have been used as stochastic methods for solving optimization and search problems, operating on a population of possible solutions. According to Darwin’s theory of evolution, the repetitive application of the aforementioned procedures alters an initial species into various other species; however, only the stronger prevail. A genetic algorithm, which is a subset of evolutionary computation, can be defined as a “population-based metaheuristic optimization algorithm.” These natureinspired algorithms evolve populations of experimental solutions through numerous generations by using the basic principles of evolutionary biology such as reproduction, mutation, recombination, and selection.
Lighting design is extremely important due to the high cost of implementation and maintenance of the illumination installations.

Evolutionary architecture explores the possibilities of buildings to improve their performance according to the demands of their inhabitants and the natural environment. These demands are dynamic, and continually change over time, so the architecture must also adapt and change accordingly. Evolutionary algorithms offer an effective solution to this problem: when architecture needs to re-adapt to the environment, the algorithms are capable of searching numerous adaptation possibilities and finding the most suitable solution, providing methods for structures to behave efficiently, and addressing well-defined construction factors such as structural, mechanical, thermal and lighting performance.
These nature-inspired algorithms can help engineers find solutions beyond imagination. In the trend of semiconductor illumination technology development and application, lighting plays a unique role in many aspects of sustainable development. For indoor lighting design, the first thing to consider is the amount of luminaires. The main requirement for the amount of luminaires is the “right illuminance” (illuminance is an indirect indicator of the brightness of an object). An excessive number of luminaires will lead to energy waste and increase lighting power density and costs. Lighting power density is an indicator meant to measure the energy efficiency of a lighting system. Second, indoor lighting design could improve lighting quality, and that directly affects the efficiency of work, physical health, psychological conditions and even the atmosphere and various effects in an indoor room. However, the diversity of indoor environments and the mutual exclusion of lighting design parameters, including lighting power density, average illuminance, overall uniformity, and maximum unified glare rating, pose difficulties for indoor luminaire layout. The main emphasis should be on designing an energy-efficient luminaire layout method for a general lighting scheme, which maximizes or minimizes these design parameters within recommended limits.

Genetic algorithms, also known as evolutionary algorithms, as an aspect of the computational thinking, are capable of generating innovative designs and objects with complex geometries in architecture that adapt to the demands of the social and environmental environment. Work with genetic algorithms began in the 1960s at the hands of the English architect John Frazer, although his ideas found greater diffusion years later through his work, An Evolutionary Architecture (1995).
Lighting design is extremely important due to the high cost of implementation and maintenance of the illumination installations. Proper illumination dimensioning is indispensable to achieve adequate lighting and reduced electrical power consumption. CAD tools are very important to the engineer design process to enable alternative simulations before the final solution, improving quality and maturity in engineering projects. In the electrical installation area, these tools have been proven suitable in several design activities. However, recent studies show that the computational facilities are still dependent on the creativity and experience of the engineer or lighting designer, which hinders a better performance from the design to the market.
Lighting design is a field of engineering that misses automatic approaches to help lighting designers. Genetic algorithms are a widely used class of algorithm for search and optimization. Many results from applying genetic algorithms for computer-generated lighting design show that the aedifiedcomparedalgorithms,bydesignedsolutiongeneticwhentotheone,providessuperioruniformity of illumination and no less than a 10% reduction in power consumption. A process to be optimized is characterized by an objective function that provides the behavior of the process, the constraints that define the search space and on which the project variables tend to assume the best value after the optimization. Many of these processes can be modeled as problems of maximizing or minimizing a function whose variables must obey certain constraints. Optimizing a process is advantageous since it allows working with a vast contingent of variables and constraints that are often difficult to visualize or tabulate, thus reducing the time spent with the process and obtaining new solutions with lower expenses.
Frazer establishes a relationship between evolutionary processes and architecture. His investigation of the fundamental processes behind the generation of forms leads him to consider architecture as an artificial life form, and to propose a genetic representation that can then be subject to processes of development and evolution in response to the user and the environment. The goal of an evolutionary architecture, Frazer suggests, is to achieve in a built environment the symbiotic behavior and metabolic balance that are characteristic of the natural environment. But, with this, he does not intend to establish a superficial analogy, but rather the creation of a work methodology that allows the development of structures following the design principles underlying nature.
54 designing lighting Additionally, this type of application allows routine processes in architecture and engineering to be streamlined and automated. Imagine automatically evaluating multiple design alternatives for the implementation of a project on a given lot. For this type of exercise, the determinants of the lot, both physical and normative, are established, and design parameters are established that direct the evolutionary verification of multiple alternatives that meet the success indicators of the project. Thus, the decision on the best option has a repertoire that broadly informs reality and supports the Inchoice.2020, Foster + Partners won a competition to design the new offices for Alibaba, the Chinese e-commerce giant, in Shanghai. Its construction will be guided by a design process based on evolutionary algorithms. The algorithm combines several aspects that are crucial to the project, such as being highly sensitive to environmental cconditions and maximizing exterior views, while meeting specific area requirements for different building functions. Another challenge to be solved is to achieve better user comfort in the central public space, protecting it from strong winter winds and harsh summer sun, while creating bespoke workspace solutions for the different departments of TheAlibaba.application
of evolutionary architecture falls under the realm of computational design, a revolutionary way of thinking about architecture that is associated with digital arts and engineering. Computational design incorporates algorithms, mathematics, and generative thinking to create innovative designs and objects with complex geometries. Through the connection between technology, society and spaces, design by data allows us to gather invisible data from the environment to integrate into structures, which gives us the possibility of creating a "living architecture" based on the environment, the context and the culture. In this framework, genetic algorithms represent one of the most interesting and disruptive aspects of computational thinking, not only because of its ability to generate different solutions to structural problems, but also because of its potential to generate new business opportunities focused on sustainability and the relationship with a changing social Soenvironment.whatdoes the future hold for genetic algorithms, and how far can they take us? In his book The Light of Evolution in the Darkness of the Universe, Dr. Çağrı Mert Bakırcı-Taylor, Ph.D. at Texas Tech University, claims that machines utilizing evolutionary algorithms will be the beginning of the technological singularity. This will not happen with some engineer somewhere coming up with a single equation, which may or may not be complex, and an artificial general intelligence emerging just like that. This is because our machine learning methods rely on extremely simplistic models of neurons, and learning based on this simplicity cannot achieve the complexity of human brains, just like overly simplified engineering designs are bound to perform worse than their evolutionarily designed counterparts, he argues. If Bakırcı-Taylor is right, and if we can overcome some of the hurdles, in a couple of decades evolutionary algorithms should be the ‘next big thing.’ If he is wrong, we might find a brand new approach, since obviously the current deep learning methods are great at special artificial intelligence but are not enough to yield a general one. What that approach could be, of course, we don't know. We just look at the history of engineering and realize that the main pattern is following the lead of nature to come up with better techniques. And if our goal is to create the most complicated, most beautiful, most powerful technologies of all times, we cannot just go with learning—we have to substantiate it with evolution. Because that is how it has worked in nature for the past 4 billion years. We'll see.

are easy to draw: find the centerlines,
57designing lighting I was first honored and then a little terrified when Randy Reid invited me to write a series for the residential section of designing lighting (dl). What could I, a residential lighting designer of no particular importance, offer such an esteemed community of award-winning designers, successful manufacturers, and hardworking lighting professionals across the world? But, I am terrible at saying no, so I drummed up a few article ideas and accepted the challenge. I started a first draft and rambled along for a couple hundred words about the need for lighting design in residential construction. Boring stuff, really, and by page three my enthusiasm was gone. Then I realized something I hadn’t before—the solution to the problems plaguing residential lighting will be found not in lighting layout or lighting design, but somewhere in between. And it is going to take courage and cooperation to get there.
HO RESIDENTIAL
Lighting Layout: Installer-focused solutions that ignore human wellbeing. Before I take a stab at plotting a new direction for the entire industry (what is that saying about pride?), allow me to catch up those of you who are largely unfamiliar with residential lighting, as I was for the first fifteen years of my career. A colleague, passionate about light but not in the profession, pointed out to me that architects, interior designers, electricians, showrooms, distributors, and manufacturers were offering a service they called lighting design to homeowners, but the results were entirely different than the service I delivered under the same name. “It shouldn’t be called the same thing,” he claimed, suggesting that lighting layouts were common, but lighting designs were rare. What is a lighting layout? You can spot them easily. If there are circles drawn in tidy rows and grids in nearly every room, if each bedroom features four cans and a fan, if bathrooms have a downlight over the sink, if kitchens have lights evenly spaced between the counter and island, if there is a downlight above the tub, you are looking at a lighting Lightinglayout.layouts
Lighting Hope: Scalable, affordable solutions for better lives. If lighting layouts fail to deliver the benefits of light, and lighting designs are out of reach for most of us, what, then, is the alternative? There is no name for the in between, the third way. This kind of lighting could be called mediocre, or okay, or marginal. It could also be called better, attainable, or sustainable. It could be called lighting help. Today I will call it Lighting Hope. Lighting Hope is a bit of a dream, a vision, for something in between. It is a strange turn of words that I will use to explore the middle ground and alternatives to the way we light our homes today. Over the course of the next few issues of designing lighting (dl), I will ruminate on the issue under the following titles: ■ Replace Edison & Redesign the Downlight

58 designing lighting make a grid, and put circles where the lines intersect. They are easy to sell: fifteen dollars each if you buy a contractor pack of ten. They are easy to install: twenty-six cans, fourteen j-boxes, two undercabinet bars, done. They help get homes built on time and on budget, but they punish the occupants for decades with glare from wafer lights that should be left in the garage and lumens spilled on the carpet instead of delivered to the countertop. The alternative I sell to clients every day is something we call lighting design.
■ Save Copper through Cooperation
Lighting Design: Beautiful custom-tailored solutions with out-of-reach price tags. A lighting design (at least how I do it) looks like a mess in plan view. Light fixtures don’t line up neatly. Single recessed downlights seem to hang out in the strangest of places. There are scary absences of recessed lights where they should be, like between the island and the dining table. There are far too many fixtures. Lighting designs are difficult to draw: aiming angles and ceiling heights and beam spreads and control zones litter the pages. Designs are difficult to sell: those recessed lights are going to cost how much?! They threaten the budget and the timeline in new builds, but they reward the occupants with decades of beautiful, functional, biologydriven lighting that supports wellbeing and life at every Lightingturn. design is my line of work, and it is a pretty good business. We’re finding plenty of clients to keep our growing team of designers busy and profitable. But profit and busyness are not what makes me truly happy. I want to make the world a better place, and that means my ultimate goal is to put myself out of business. I want lackluster lighting layouts to be abolished and expensive lighting designs to become irrelevant. I want something different, something in between.

59designing lighting
Why are we still selling traditional switches and dimmers designed for line voltage, fixed white lighting when we know that natural light is a critical source of inspiration? How could we, as inventors, deliver a new light switch that would change the way homeowners interact with light every day? Why are horizontal illuminance levels our most common calculation for homes, despite no homeowner ever taking a light reading on the floor? How could we, as technical experts, make light more understandable and accessible to the average homeowner? Why is good lighting found in luxury homes and rarely—if ever—anywhere else? Why do those living in apartments suffer subconscious but very real damage from bad lighting? Why do hundreds of millions of people increase their risk of premature death by relying on light from burning wood and fossil fuels? How could we, as humans, help our neighbors live better lives with better lighting? Courage is needed, because we need to consider changing everything from the lights we sell to the way we use them, and from the way we do business to the words we use. I do not have all the answers, though I will ask the questions over the coming months because I believe that we, the lighting industry, do have all the answers. We simply need the courage to consider changing everything, to step outside of the way things are and imagine the way things could be. Together, we can make the world a better Andplace.that is reason enough for hope. ■
The rather odd-sounding concept of Lighting Hope is an invitation for us to use everything we know about light and lighting to make the world a better place, starting with our friends, family, and neighbors, and extending around the globe. Lighting Hope is not yet easy, popular, or profitable, but it does offer us the opportunity to rethink the tools we use and how we use them. Over the coming months, I hope to at least get closer to answering the following questions.

Why are homeowners and builders reluctant to use recessed downlights with built-in LED modules in place of the beloved 150-year-old E26 base? How could we, as manufacturers, offer them hope instead of fear of incompatibility and premature failure? Why is low voltage lighting struggling to make headway in residential markets, despite nearly every fixture containing a low voltage LED source? How could we, as an industry, cooperate to change the future and conserve resources like copper?

The challenge of cost continues to be the elephant in the room on any project. Ultimately, a networked lighting controls solution is more costly than standalone systems but offers a plethora of benefits in the long term. A project is often stripped of its beauty and functionality through the rigorous process that is value engineering. One of the first items to be axed is lighting and controls. In the majority of applications, the bare minimum to allow for code compliance is left. Typically, these are standalone controls with dimming and/or occupancy timeouts. What we often overlook is that some lighting control manufacturers, such as Casambi and Crestron, use the same "building blocks" of devices for both standalone and networked applications. This means that the same in-room devices, such as load controllers, occupancy sensors and keypads, are used whether standalone or networked applications. Standalone systems that have the ability to turn into a networked system and those "Any sufficiently advanced technology is indistinguishable from magic."
A networked system is also capable of tying into other connected systems within the building such as BAS, security, fire alarm, AV, IT systems and more. It puts the power of data into the end users' hands with the ability to track occupancy, monitor energy consumption, master controls and even make adjustments to the function of the devices throughout their building or even multiple buildings. This differs from a
A networked lighting controls system allows for the communication of wireless or wired control devices in a single space to other areas of the building. The communication and function of these distributed room devices is controlled by a centralized device or app, acting as the command center. This system takes the controllability of the space further with timeclock functions, controlling multiple spaces together, master keypads, and integration of touchscreens.

How do we do this? Simple!
This means we can phase out the scope of intelligent lighting controls such that there is the eventual ability to have a fully sophisticated system down the line.
In future budget allowances, bring in the networking hardware and commissioning of the system. Technologies like Casambi take this one step further by not requiring a processor to turn a standalone solution into a networked one. Casambi’s nodes live in load controllers, light fixtures, switches and sensors to create a low-energy bluetooth mesh system to control any number of lights in a room, floor or building. Some projects may even have the possibility of not requiring additional hardware and installation. The future phases can purely be time spent commissioning the system to be better and smoother. The more commissioning time, the extra layers of sophistication we can bring to a system. This includes but not limited to adding harsher timeouts, dimming further to reduce energy consumption, integration across other building systems and others.
Note to stay consistent with in-room device manufacturers throughout the various potential phases of projects. The fewer manufacturers, the less need to manage multiple systems and complex scopes of integration and restriction each manufacturer brings. The scientific advancement of modern-day lighting control technologies has allowed lighting controls to be the eyes and ears of your building to provide significant amounts of data to further optimize solutions. This phasing of projects using standalone lighting controls with the flexibility of future networking capabilities allows for there to always be the opportunity for your building to have the sophistication it needs and deserves and puts the magic of the building into the users' hands.■
Start with a list of manufacturers that use the same in-room devices for networked and standalone systems and create designs with both. During tender, make sure that standalone devices that do not have the flexibility and scalability are not included in the package. Install as much of the hardware as possible to minimize the overall cost down the road. Items like processors and gateways can be added to the project as part of a future phase. Confirm if running additional cabling prior can be included as part of the scope if the budget allows for it.

Every day on my way to work, I pass by a work of art that always catches my eye. It is beautiful, yet simple. It is a series of interconnected poles, each one resting on and supported by another. Without its neighbors, each would fall to the ground. But together, they keep each other upright. The important truth distilled in this simple piece of artwork is that our personal and professional lives depend so much on the support and guidance of others. This is especially true for young professionals figuring out what to make of their careers and their lives. Every Plato needs his Socrates, someone to stoke the fire of creativity and passion within himself. Someone with real world experience who has navigated the challenges of professional life.

The Silhouette Awards, Merging Steel by Steve Benneyworth
64 designing lighting
A strong belief in the importance of mentorship led Eve Gaut of Parrot PR and Marketing and Katia Kolovea of Archifos to create the Silhouette Awards in 2021. The goal of this global program is to “identify the rising stars of the lighting industry,” wherever they are, and support them as they grow their careers. The name might be a little misleading—it is not a traditional awards program. Rather than receiving a trophy or certificate, the winners are awarded with a 6-month mentorship with an industry leader. I have followed this program since this past January, when the inaugural winners were announced. Now that the first round of mentorships are wrapping up, I spoke with the mentors and mentees to find out how the program went. To my surprise, almost everyone I reached out to enthusiastically agreed to share their experiences. The Process When the Silhouette Awards began in the fall of 2021, Eve and Katia contacted twenty well-established and notable lighting professionals to serve as the inaugural mentors. They then opened up the program to applicants who were asked to submit a 3-minute video in which they described themselves, their mentorship goals, and another passion outside the lighting industry. All videos were then reviewed by the mentors, who chose their top 20 out of a field of more than 50 submissions. They also picked their top 5 – the applicants who they felt they could help the most. Sam Koerbel, one of the mentors, emphasized how difficult this process was. “Everyone who applied was 100% qualified, so it was really about creating the right fit between the mentors and mentees.”
PARKER ALLENBy an Awards Program with a Twist
The Mentorships
The mentorships were not free from obstacles. Even the best made plans must change when real life gets in the way, whether it be a job change, a difficult project, a growing family, or a health issue. The starkest example of this was the pairing of Anna Sbokou and her mentee, Valeriya Gorelova, who is based in Moscow. They had barely begun their mentorship when the war in Ukraine erupted. All of a sudden, lighting took a backseat to much more pressing issues. The original vision for the mentorship changed dramatically, as they found themselves discussing backup plans rather than lighting design. However, there was a silver lining–Valeriya was given some time to evaluate the relationship with her partners, discuss marketing plans, and figure out what they need to have in-house. This was an opportunity that she wouldn’t normally have had. One thing that stood out to me was how little of the relationship revolved around lighting design. Though lighting was the thread that tied this entire program together, both the mentors and mentees mentioned that few of their conversations were lighting specific. Many of the mentees came into the program with lighting careers already established, so much of the focus was on personal and professional development, on opening doors and inspiring new opportunities. As Iris Molendijk, a mentee, said, “The mentors don’t have to fill things in completely for you, but they can start the drawing and empower you to finish the sketch.”
One mentee mentioned that she would have liked some time to settle in and get to know her fellow mentees before the program began. The clock started when the winners were announced, and she wasn’t expecting to be a winner, so she was caught off guard and underprepared.
The first challenge these pairings faced was getting to know each other. Àfrica Sabé Dausà compared that first meeting with her mentor to a first date. Their initial meetings were dedicated to getting familiar and discussing interests. From that point on, there were very few rules or constrictions – the pairings were free to tailor their relationships and their time together to what best fit Multiplethem.participants highlighted the importance of timing. It began in late 2021, when the world was still experiencing the disruption of the pandemic. Though our shift to a more virtual world is advantageous in some ways, it also presents challenges. Conversations and connections can’t happen as organically as they used to—everything has to be scheduled. Want to talk about a new idea for a project? Let’s set up a Zoom meeting. The effect this has on young professionals, to whom forming connections and collaborations is vital, cannot be overstated. When she heard about the program, Gabi Kourac thought it was the perfect opportunity. “I needed a buddy,” she quipped. The Silhouette Awards provided this opportunity to form a personal and creative relationship with a fellow lighting enthusiast, one who the mentee would never have connected with otherwise.

It is reasonable to expect that submissions will grow as more people learn about the program. Naturally, an awards program can be selective but there are many young talents that could benefit from a mentor. In the future, perhaps they will increase the number of mentors to accommodate all of the deserving applicants. Perhaps they will change the program from a set time period every year to a rolling basis so that young professionals are always being paired with a mentor.
Overall, the experiences of both the mentors and mentees were overwhelmingly positive. Some are planning on future collaborations. Others are planning to meet in person as soon as they have the opportunity.
Several of the participants were pleasantly surprised at the deep connection they formed with their partners.
What started out as monthly meetings quickly evolved into regular texts and emails. Monica Luz Lobo, a mentor, stated that the most important thing she got out of the program was a new friendship—she and her mentee grew together, and now have a relationship that will last their entire lives. The Future The initial iteration of this program was wildly successful, butit will no doubt face some growing pains as it matures.
The mentors even created a WhatsApp group where they could all chat and share their experiences with one another as well as with the second round of mentors. A worldwide community of lighting professionals is forming around the Silhouette Awards. Every pairing that I spoke with is planning on staying in touch. That’s the sign of good pairings. That’s the sign of a good program. That is a program that is here to stay. ■
The winners and their mentors were announced at the end of January with each mentor paired with a mentee in their top 5. Now, six months later, the mentorships have officially come to a close—though, as I found out, this is really just the beginning of these relationships.
Europe is facing more challenges than before, mainly because they are impacted to a greater extent by the war than North America. Additionally, Germany is experiencing labor strikes at key ports, furthering congestion, backlog, and uncertainty. Much remains to be seen as to how the supply chain will look at the end of the year, but we are finally starting to see the adaptations and adjustments pay off to an extent.
Supply chain has been the focus of many businesses in the last couple of years, with recent quarterly reports and earnings calls addressing logistical woes and strategies to adapt to the situation. While the current state of affairs is far from being stable, there is reason to be cautiously optimistic. The latest market update published by Maersk, one of the world’s largest global container shippers, details changes observed in the global supply chain. Much of it is shrouded in uncertainty, as the full extent of the geopolitical fallout due to the Russian-Ukraine conflict is yet to be seen. However, they pointed to a few improvements in supply chain operations, something that would’ve been considered wishful thinking in months Apast.key point of interest is the gradual improvement of the Asia Pacific to North America route. Waiting time at major ports like Long Beach and Los Angeles has decreased slightly to 15 days, with export volume expected to increase in coming months. Vancouver also saw a reduction in wait time, but yard density is still severe. However, other ports continue to worsen, and demand remains stable at a very high level. On Asia Pacific exports, Shanghai is beginning to return to normal after a lockdown in April and May caused by a COVID-19 outbreak. Factories are starting to get back in full swing and demand has returned. Many other operations in China, like city area and interstate trucking, has returned to pre-lockdown levels.

Before COVID, Jill planned for expansion as she realized the benefits of diversifying geographically. She chose St. Louis as a second location for only one reason—that is where Dark Light Principal Ron Kurtz lives. Jill explained, “Seattle has been a great place to start Dark Light because the city has experienced so much growth, but we need expertise in other geographic and design areas.” She highlighted that Ron brings experience diversity with his strong footprint in hospitality design. Dark Light has worked on projects for several big clients including T-Mobile and Microsoft. Jill admitted that sometimes you just get a project randomly and then you build on it. She said, “We have been really fortunate because there’s so much tech work going on in our market.”
Many of the spaces are open floor plans with meeting rooms of various sizes, some as small as accommodations for two people. Tech clients typically want the amenities space to provide a different environment, not just a break room, but for collaboration as well. Jill practices Dark Light's style of dichotomy, "If a person is working under 30-footcandles of uniform light and they are there for a long time, they need a break. Our goal is to provide visual relief when outside of those main workzones."
Jill concluded by explaining the importance of her team and she attributes their tremendous growth to the incredible people she works with which now includes Ron in St. Louis and the rest of the team scattered around this country. She also expressed her good fortune to be working as a lighting designer, a profession that makes a real difference, and that has so many amazing people.
■ 72 UP CLOSE with JILL CODY
Another area of expertise is higher education. Jill mused that students get exposed to her lighting design at various universities, then upon graduation, some experience Dark Light designs in Seattle at many of the tech companies.
Jill first thought of the name Dark Light during an education seminar at Lightfair. She recalls, “There were these two presenters from Norway giving an esoteric presentation. They began discussing the importance of darkness to complement light and it really resonated.” She felt strongly about not naming the firm after herself. Thinking about the 2 or 3 hours of daylighting that Norway experiences in the winter, Dark Light was born. She continued that so much of what a lighting designer does is not just lighting objects, but deciding what not to light. “You can’t drive focus if you light everything. So, the name implies that we are thinking more than just the additive, sometimes it is the subtractive.”
Jill Cody began her lighting design firm almost by accident. After working for HGA in Milwaukee, she moved to Seattle with her husband and discovered almost all lighting design there was provided through engineering firms. An architect hired her to design a Coeur d'Alene, Idaho resort. At the time, she had no desire to set up a business and worked out of the architect’s office. After being in demand by word of mouth, she opened Dark Light. This has given her the flexibility to chose the clients and projects she works with. And, she emphasizes that both groups are remarkable!
Jill doesn’t use the word "nighttime", instead she says “after dark”, because Seattle can be dark at 4:00 pm in the middle of December. Her specifications use a lot of 3000K, not because of freezing cold temperatures, but because of sad and dreary winters. She strives to give clients a lantern effect. On Dark Light’s choice not to specialize in particular project types, Jill stated, "The truth is that's the way we work. Yes, there are certain technical requirements of certain jobs, but at the end of the day we’re doing the same thing for all of our projects. We are lighting a task or creating focus and enhancing the materials that are important to the architect.”
