As I approach the later stages of my career, I took a week to enjoy the serene beauty of Wine Country. Most of the articles in this issue were penned in the peaceful quiet of the early morning hours. While reflecting, I learned a valuable lesson about people—one that reminded me of the strength of industry connections.

Never underestimate the importance of a casual conversation.

Tim Conaster, an electrician from St. Helena, CA, wanted to learn about lighting design and decided to attend LightFair in 2022. Tim shared with me that he was already familiar with the EdisonReport and had stopped by our booth during the show. While I regret that I don’t remember much about our initial conversation, the story that followed demonstrates the incredible opportunities that trade shows like LightFair provide.

After our meeting, Tim crossed paths with Mark Roush, who engaged him in a meaningful 30-minute discussion. Tim mentioned his interest in learning more about lighting design, prompting Mark to recommend he speak with Dr. Craig Bernecker of The New School at Parsons. Mark tried to call Craig on the spot but was unable to reach him. Tim made note of his name—scribbling it on the back of Mark’s business card.

Upon returning home, Tim took action. He enrolled in an online course at Parsons to pursue his Interior Lighting Design Certificate. To his surprise, the instructor for the course turned out to be Craig Bernecker himself. The serendipity of meeting Mark and the direct connection to Craig only solidified Tim’s trust in that LightFair conversation.

Since LightFair, Tim and I have kept in touch. During one of our conversations, he told me about a lighting design project he was working on—coincidentally in St. Helena where my wife Lori and I were planning a stay with Terry and Anne Clark. The timing was perfect for me to reconnect with Tim, see his nearly completed project, and witness firsthand the result of his dedication to lighting design. The project will be featured in LM&M early next year, showcasing Tim’s impressive design and electrical work.

Tim’s journey is a powerful reminder of why events like LightFair are so important to our industry. Without attending the show, Tim wouldn’t have met Mark Roush, wouldn’t have learned about Craig Bernecker, and perhaps wouldn’t have pursued the lighting design certificate. That chance conversation turned into a sequence of events that ultimately shaped his career and introduced him to new opportunities.

To this day, Tim keeps Mark’s business card in his wallet, with Craig Bernecker’s name still scribbled on the back—a tangible reminder of the value of meaningful connections.

This is why trade shows like LightFair matter. They provide a space for casual, yet meaningful conversations to evolve into transformative connections that propel careers, foster learning, and create lasting relationships. ■

More Than Meets the LIGHT EYE (and the Brain)

By

JAMES R. BENYA, PE, FIES, FIALD

Long before the phrase “human-centric lighting” was coined, there were concerns about possible health and well-being implications of electric lighting. For example, circadian effects were known and understood, although the actual biological mechanism was not discovered until the late 1990s. Among other negative qualities of electric lighting, flicker was well known to be a problem with certain human maladies like photosensitive epilepsy, where flashing lights, flickering fluorescent and neon lamps, fireworks or highly contrasting patterns could trigger a seizure.

The cause? In simple terms, AC power causes flicker. AC power creates 120 pulses per second of light in North America (100 in Europe and many other places) that are particularly noticeable when viewing a moving object.

All in all, flicker has truly been an on-again-off-again challenge1, in more ways than the obvious. Throughout the history of anthropogenic (“man-made”) lighting, the common light sources have varied between flicker-free and really bad, annoying, make-you-dizzy flicker. Incandescent lighting is pretty good because, even when used on AC circuits or with dimming, the heat of the filament causes it to continue to glow even as the voltage changed from positive to zero to negative. This is called persistence. Persistence allowed the solid-state electronic dimmer invented by Joel Spira2 to work on AC power with

incandescent lamps without causing much flicker.

Meanwhile, fluorescent lighting became important in general lighting for economic reasons. But the original fluorescent lamps emitted 120-hertz flicker which was noticeable and often irritating, if not the cause of nausea or worse. Two-lamp magnetic ballasts solved the problem by making the pulses peak at separate times to almost totally negate the flicker. Then, in the 1980s, high frequency electronic ballasts (including dimming ballasts) operating at 50 kHz or more eliminated flicker from our fluorescent lighting vocabulary. For a period of 30-35 years, the electronic ballast solved the flicker problem for fluorescent lamps, and flicker problems sort of vanished.

Then along came LEDs. LED lighting promised to give us a whole new way to light with lower first costs, less energy use and tremendous flexibility. The light emitting diode is, after all, a diode which is a basic electronic component. Hook it up to a battery or DC power supply, and an LED produces more light per watt of electricity than any other light source that could be used in an inexpensive luminaire, lamp or even a toy. The light it emits is smooth and flicker free as well as energy efficient.

But we don’t use DC power to light buildings. Edison lost to Westinghouse3 because AC power has the ability to change voltage using transformers. So today, every LED luminaire or LED

“LED lighting is wonderful in all ways except that, to vary it, we have to dim it. We need to stop and resolve the flicker problems, and it may take new technology.”

replacement lamp has a driver that rectifies AC to DC4. And here comes the problem. In North American it is called “pulsing DC” at 120 hertz that causes LEDs to emit pulsing light, which is flicker, with all of its issues including being a visual distraction and affecting persons who are sensitive to it.

It’s possible to smooth out the pulses using capacitors, but capacitors are big, expensive and sensitive to heat. They are used in encased LED drivers where there is room but seldom in inexpensive and/or compact drivers. And generally not in linear LED lighting.

In my own home, we love LED linear cove lighting and undercabinet lighting, and we endure flicker because we want to be able to dim it. A long string of LEDs, such as for cove lighting, can’t employ high frequency DC because of significant losses along the string. These losses are the result of distributed inductance and capacitance in the string itself, and to make matters worse, the string becomes a radio transmitter that can cause radio frequency interference. And in our case, we operate the lights at full most of the time, rarely dimming and suffering flicker when we do. And tolerating

when we really want to dim.

That said, I chose to write about this because I am aware of significant potential health and wellness issues resulting from flicker. Possible issues related to flicker include headaches, migraines, epileptic seizures, autistic repetitive behaviors, eye strain and fatigue, stroboscopic effects that make moving machinery appear to be standing still, and reduced visual task performance5

These issues stem from the hard-to-fix challenges of dimming LEDs. The scientists at the US Department of Energy (DOE) identified flicker as a problem associated with LEDs that could limit their acceptance and success. Pacific Northwest National Laboratories (PNNL) began research into flicker, also called temporal light modulation (TLM), in earnest. For starters. I recommend you download and watch Flicker Basics, a web page that offers Naomi Miller’s brief video6 of the same name. As she states, “ LED lighting is wonderful in all ways except that, to vary it, we have to dim it. We need to stop and resolve the flicker problems, and it may take new technology.” ■

From Blueprint to Byte

Navigating the Digital Transformation of Design

By PARKER ALLEN

The design industry is experiencing a profound shift as digital tools reshape traditional workflows and introduce new possibilities. In a recent webinar entitled "Digitization in the Design Practice," hosted by Business of Light, key industry leaders discussed the implications of digital technologies on design firms, from improving margins to fostering creativity.

The expert panel included Rachel Fitzgerald, Principal, Discipline Lead, Lighting at Stantec; Jay Wratten, Senior VP and Digital Lead at WSP USA, and Samuel Mikhail, Managing Director at 4 Ideal Design and NYSID’s MPSM Program Director. David Ghatan, President of CM Kling + Associates, served as the moderator.

Defining the Digital Practice

Samuel Mikhail set the stage from the outset, reminding the audience, “Your digital journey begins the second you hold an iPad or sit in front of a computer.” From software suites like Adobe and Microsoft to more specialized platforms such as AGi32 and LightStanza, these tools form the backbone of a digital practice.

The question that each firm must answer is the extent to which the myriad of tools on offer will be utilized, and how they will go about successfully implementing these tools into their design practice.

Gone are the days of receiving blueprints in the mail. The pen and the pencil have been replaced by the stylus. Rachel Fitzgerald recounted Stantec’s shift from a two-dimensional AutoCAD world to the 3D realm incorporating BIM (Building Information Modeling)

and Revit. This transition wasn’t without its challenges, she noted, but ultimately, this shift in their workflow has unlocked greater creativity and problem-solving potential early in the design process, rather than reactivity during construction

Importantly, digitization is more than just using specific advanced tools – it’s about adopting an entire ecosystem of interconnected software that requires a carefully managed transition. “I think you reach a tipping point, and you have to rip the band-aid off,” explained Fitzgerald.

The challenge for firms is to adapt quickly while ensuring that all collaborators are aligned

The Human Element: Bridging Generations

One challenge to be navigated is the generational divide in adopting digital practices. The key to a successful digital transition is balancing the experience of senior staff with the digital fluency of younger designers. The younger generation is often more adept with digital tools, but senior staff bring critical insights from their years of practice. Finding a way to integrate both groups is crucial for firms looking to stay competitive in an increasingly digital world

Wratten noted that many decision-makers within firms are less familiar with digital technologies than those on the “front lines,” and so firms find themselves being driven from the “back of the bus.” This can hinder innovation, as these companies may fail to fully explore the capabilities of their digital toolsets. The solution is to foster environments where new ideas are encouraged and integrated into daily practice.

Standards and Flexibility

Establishing digital standards is another critical aspect of running a successful digital practice. Mikhail pointed out that developing comprehensive BIM standards, coupled with staff training and project mentoring, form the core of any digital strategy.

However, no two projects are the same, and each requires a tailored approach, making adaptability just as important as standardization

Tools and the Future

The next topic on the menu was the ever-evolving nature of digital tools. Currently, Autodesk dominates the market, but even within that single suite are a host of programs, similar to Apple’s app store, offering advanced design capabilities. Mikhail advised, “You have to figure out what are the software programs that are going to best fit your needs. Identify your need first, and then go shopping. No window shopping!”

And no conversation can be complete without at least a mention of artificial intelligence, which is becoming a key part of many designers’ toolkits. For now, the use cases primarily center around the creation of realistic concept renderings that help clients visualize lighting's impact. But as the power of AI continues to increase, so will the possibilities it unlocks.

The future holds immense potential for new digital tools, but firms must decide where to invest their resources. It’s all about return on investment—determining which tools will truly enhance a designer’s abilities and contribute to better project outcomes

The Digital Ecosystem

Digitization in design is not just about adopting new tools— it’s about creating a digital ecosystem that integrates various technologies into a cohesive workflow. Whether it’s improving efficiencies with BIM, fostering creativity through 3D visualization, or preparing for the next wave of AI innovations, design firms must leverage an ever-increasing menu of digital tools to enhance productivity, creativity, and efficiency, striking a balance between technology and human expertise.

The firms that can successfully navigate this landscape will be best positioned to thrive in the evolving digital world. ■

Importantly, digitization is more than just using specific advanced tools –it’s about adopting an entire ecosystem of interconnected software that requires a carefully managed transition.

The Heat Is On But No One’s Around

Unlike when lights are left on in vacant spaces, energy waste from operating mechanical systems in vacant spaces may not be as obvious. But some have taken notice and are looking at ways to integrate lighting controls with mechanical systems to save energy and prepare buildings for future energy management needs.

Energy codes for commercial projects in North America require increasingly strict and complex lighting controls. While standalone room-level lighting controls may make sense for small projects, luminaire-level lighting controls (LLLCs) are

providing new flexibility for many commercial buildings.

Recently, I spoke with specifiers, facilities managers, energy service personnel, and manufacturers who are successfully working with LLLCs to save energy, both with lighting and HVAC systems. Their projects are using occupancy data from LLLCs to send a signal to the mechanical equipment to automatically adjust thermal setpoints or reduce air flow. LLLCs provide an opportunity for reducing HVAC energy use, especially in spaces with intermittent occupancy patterns like businesses with workfrom-home policies.

Integrating Luminaire Level Lighting Controls with HVAC Systems

In addition to increasingly strict requirements for lighting controls, recent state and model energy codes (e.g., California T24,1 ASHRAE 90.1-20222) also require that mechanical systems in commercial buildings automatically adjust thermostat setpoints when the space is unoccupied. While there is no requirement to use LLLC sensors to control HVAC equipment, Tim Carr, Senior Energy Consultant with Vermont-based VEIC, noted that avoiding the use of separate occupancy sensors for mechanical equipment offers material and labor savings.

Aprille Balangue, electrical engineer at TFNB Engineers in Seattle, pointed out an aesthetic benefit in using wirelessly connected LLLCs to avoid the clutter of additional controls wiring. Reduced conduit looks good, especially with her region’s use of exposed cross laminated timber construction.

Doug White, Energy Services Lighting Product Manager for Trane Commercial, further explained that retrofit customers benefit not only from installation cost savings of wireless LLLCs but can also avoid asbestos abatement issues.

What’s the Holdup? Silos and Uncertainty

Integration case studies,3,4,5 show a wide range of HVAC energy savings, which is part of what makes this integration difficult for utilities to incentivize on a prescriptive basis. Jarad Adams of Alpha Engineers described a 2020 bank project in which his team successfully integrated lighting and mechanical systems. Because the utility did not offer incentives, however, it was not cost effective to use LLLCs.

Using lighting controls to deliver a signal to HVAC equipment represents significant challenges, both in terms of equipment and siloed expertise. Typically, these systems require customized integration with a large building’s BACnet system, variable air volume dampers, thermostats, security firewalls, etc. To spread the fixed costs of integration over a larger area, the U.S. General Services Administration6 recommends integrating these systems on projects greater than 50,000 square feet.

Not all projects are suitable for this type of integration. Constant air volume systems, for example, are less successful than variable air volume systems.7 Particularly successful projects are ones in which occupancy is sporadic and a time clock would not capture savings opportunities. A library (shown above) in Castle Rock, Colorado, is actually not using their integration features; facility manager Dave Meyer explained that, other

than a few staff-only spaces, their library is occupied at all hours of the day and night and would not benefit from LLLCcontrolled temperature setbacks.

The main challenge to integrating these systems is promoting collaboration between lighting and mechanical experts, both in the design stages and during construction. Collaboration should ideally begin early in the project’s design due to the significant equipment coordination required to properly implement these systems.

As for the construction phase, Mark Lane, a controls specialist at nLight, added that because these systems are controlled by two completely different groups (Constructions Specifications Institute8 [CSI] Division 23 vs. 26), a project’s electrical and mechanical contractors need to separately verify their respective systems are working in order to get paid. Any interconnection problems will hamper timely payment.

More recently, integrated cross-functional controls have been defined in CSI Division 25 (“Integrated Automation”). But bridging these systems is not “cookie-cutter” operation; integration requires a rare expert who understands customer intent and who is responsible for carrying the integration through from design to commissioning.

Aprille Balangue pointed out that commissioning these systems can be especially challenging, and contractor programming time is limited, so it is important to write a Sequence of Operation (SOO) in the early design stages that will be understandable and specific to each room. (For more about Sequences of Operations, see Jim Benya’s article9 in the Oct/ Nov 2024 issue.)

Q Gagne of Minnesota’s Center for Energy and Environment agreed that integrating these systems requires an uncommon level of expertise and cited the need for more scalable technology, with an intuitive interface (such as smart phone app) so experts don’t have to fly across the country to commission and troubleshoot. Q predicts integration success led by the HVAC community because they more commonly work with complex SOOs.

Q’s prediction resembles the innovative approach Doug White has been taking at mechanical equipment manufacturer Trane. His group is working with both new buildings and existing clients to specify luminaires and lighting controls that will talk to Trane’s building automation systems. Trane can provide the lighting and controls equipment, and their energy monitoring

Occupancy data from integral sensors such as this can be used to control mechanical systems.

software can use LLLC sensor data to adjust thermal setpoints after installation by local contractors.

A similarly innovative approach to integration is offered by Jeff Burns of building automation controls manufacturer Magnum First. The company can perform the site audit and system design, pre-program and bundle the material for each room, and work with local energy service companies to perform the installation. Magnum First acts as the controls manufacturer, distributor, and the integrator, returning to the site to commission the systems.

By bridging between lighting and mechanical expertise “silos,” integration service providers can limit the number of people to call when equipment eventually requires updating.

Modularity

Several people advised against installing a lighting control system that will need to be torn out when integrating in the future. Kenny Seeton of California State University, Dominguez Hills recommends choosing lighting controls that work well with BACnet, as well as standardizing across the campus to enable growth over time.

Doug White expressed a similar perspective which he characterized as “crawl-walk-run.” Because many of his clients need to gradually add spaces to a larger building management ecosystem, he favors lighting controls such as LLLCs that enable a modular approach to eventual integration.

Future of Integration

Increasing electric vehicle charging and building electrification will place greater demands, not only on the electrical grid,

but also on the building’s electrical infrastructure. Energy management from these types of systems support future building needs.

Greenhouse gas emissions may be limited by the state or municipality, or even the company’s shareholders. More clients have decarbonization goals and will need detailed energy analytics to support accountability for energy use, and integrated systems can enable these types of insights. LLLCs allow flexibility in the future, both in terms of space changes and limiting future costs in labor and material.

By integrating building systems, facilities can use lighting controls to support electrical demand management. Chris Wolgamott of Northwest Energy Efficiency Alliance explained that by using LLLC occupancy data, building owners will be able to predict their needs more precisely, shifting power use away from peak hours to times of lower power demand. Jeff Burns gave an example: during times of peak summer power demand, his firm programmed a large grocery chain to pre-chill the building during low demand periods, then coast through peak demand period. With trends toward increasing electrification, this sort of demand management will help the utility maintain service and reduce customers’ utility bills.

Artificial intelligence with integrated building systems offers opportunities to recognize the occupants’ habits, and preemptively turn up the heat before the occupants typically start arriving, thus overcoming concerns about thermal inertia and occupant comfort. By using weather forecast data, these systems will be able to learn what portions of the building will likely overheat, and preemptively adjust the cooling to maintain occupant comfort. By predicting occupancy patterns, LLLCs will play an increasingly important role in future energy management in our built environment. ■

DUELING IDENTITIES

RANDY REID By

The owners of Proper House Group set out to design two distinctive yet interconnected venues in Tampa, each with a unique ambiance. The first, Ash, is a vibrant, light-filled restaurant, while the second, Alter Ego, is a sultry, moody cocktail lounge. Despite their contrasting atmospheres, the two spaces are united by a shared kitchen connecting their operations. Kristin Pickar-Knussmann, Principal of KPK Lighting Design, LLC, was hired to conduct the lighting design. Her team included Natalie Anderson and Juanita Fadul.

Ash: A Space of Curves and Light

Ash operates as a dining haven, serving three meals daily with a menu as expansive as its airy ambiance. Pickar-Knussmann, collaborating with the interior designer, Gin Design Group, and the owner, prioritized soft curves in the lighting design, creating a cohesive visual language throughout the restaurant.

The focal point of the bar area is a curved pendant from

Designing Lighting for Two Unique Spaces

The ceiling design features a cloud-like soffit outlined with LED neon, enhancing the spatial curves with a soft glow.

The space integrates various forms of linear lighting. Behind the stainless-steel bar shelves, Pickar-Knussmann placed field bendable metal extrusions with high density tape and milk white lenses in architectural pockets and behind floating metal shelving, producing warm indirect illumination and sparkle for bottles on the back bar. This accentuated the curves of the shelving while creating depth and drama.

Task and accent lighting for tables were thoughtfully implemented using Ecana 3-inch recessed adjustable fixtures from Lumenwerx Pickar-Knussmann specified fixtures with a spot optic and linear spread lens for a narrow ellipse of light on the banquette tables. This allows for table placement flexibility, ensuring even light coverage regardless of how tables are grouped.

The bar itself presented an unconventional lighting challenge. Kristin chose uplights with frosted lenses to avoid interrupting the smooth lines of the terrazzo bar top. These diffused uplights provided a subtle, even illumination that avoided harsh shadows or distracting contrasts when people moved around the bar.

Alter Ego: The Dark, Sultry Cousin

Next door, Alter Ego delivers a completely different vibe—a moody cocktail lounge perfect for latenight revelers. The lighting design here centered on creating drama and intimacy.

Pickar-Knussmann coordinated with the interior designer to create a custom floating cloud fixture, with TechoLED top-bending LED neon to outline the shape and Lumenwerx adjustable accents to spot light the cocktail tables. To maintain the dark aesthetic, the room’s storefront windows are

Underneath the drink rail, Prizm by American Lighting tape light ensures functional task illumination without compromising the ambiance. Pickar-Knussmann opted for a field-bendable metal channel with snap-in acrylic lenses for the curved shelving behind the bar, achieving seamless, diode-free lighting that complements the flowing shapes.

The lounge also features backlit panels alternating between plush fabric and reflective metal. This interplay of textures is further enhanced by precise mounting and cabling, ensuring a flawless finish. The reflective metal panels catch and diffuse the light, amplifying the room’s dynamic energy.

Balancing Technical Challenges

Both spaces shared technical challenges that PickarKnussmann navigated with care. For Ash, the cloud ceiling required minimizing ceiling penetrations, while the linear light integrations had to preserve the clean, curved aesthetic. Alter Ego’s design required innovative solutions for mounting remote drivers and concealing cables in the acoustic ceiling tiles above the kitchen. The specification of Lutron’s Pico control system enabled flexible dimming for both spaces, ensuring the lighting could adapt to different moods and functions.

Integrating lighting with the kitchen design presented a unique challenge due to the contrasting atmospheres of the two restaurants. In Ash, the semi-open kitchen aligns with the vibrant, open-concept design, allowing the kitchen to be visible. Pickar-Knussmann collaborated with the kitchen equipment manufacturer to incorporate dimmable tape lights into the stainless-steel appliances, providing cohesive task lighting. However, the bright kitchen lighting could disrupt the lounge's moody ambiance in Alter Ego. To address this, she ensured that the corridor to the kitchen featured dimmable lighting, maintaining the sultry atmosphere even when the door opened.

Designing Under Constraints

Despite the creative freedom, value engineering impacted the project. Pickar-Knussmann worked closely with the electrical distributor to maintain the design's integrity while staying within budget. Her persistence paid off, as both spaces deliver visually stunning and functionally effective lighting designs.

A Harmonious Contrast

Ash and Alter Ego may be conceptual cousins, but their lighting tells two completely different stories. From the soft curves and bright ambiance of Ash to the dramatic, dark sophistication of Alter Ego, the KPK team’s thoughtful lighting design and on-site execution elevate each space’s identity while tying them together through subtle threads of design consistency. These spaces showcase the transformative power of lighting and underscore the importance of collaboration, technical expertise, and creative problem-solving in achieving extraordinary results. ■

LIGHTING INNOVATION AT A Design Story TASH WELLNESS CENTER:

Nestled in a 5,000-square-foot space in a suburban strip mall, TASH Wellness isn’t your typical fitness facility. It’s a space where strength and wellness take precedence over intensity and sweat, offering personal and small group training with an emphasis on function, longevity, and community. But perhaps what makes this space truly remarkable is its lighting design—a testament to how thoughtful lighting can transform even the most straightforward spaces into something extraordinary.

The project, led by Sean Murphy and Avraham Mor of Morlights, is not just about creating a visually appealing environment. It’s about rethinking the role of lighting in wellness spaces and how it impacts functionality, mood, and acoustics. Mor’s mother, Sharan Tash, is the owner of the facility, making the design process personal as well as professional.

When Sharan first envisioned the center, her plans included a black ceiling and basic lighting. Murphy and Mor, however, had other ideas.

“Imagine lying on a bench, looking up at a black ceiling with bright lights glaring in your face,” Mor recalls telling her. “Why would you want that?” Instead, they proposed a clean, white ceiling paired with suspended acoustical lighting fixtures that would improve illumination and also tackle the inevitable noise challenges of a hardsurfaced fitness space.

The result is a sleek, functional design that redefines the typical strip-mall workout environment. It demonstrates that even smallscale projects can benefit immensely from professional lighting design, offering a model for how similar spaces could be approached.

Designing for Function and Comfort

The lighting system at TASH Wellness was built to address the specific needs of its users. The space incorporates customized fixtures from Focal Point, chosen for both their aesthetics and their acoustical properties. These fixtures—the Seem 1 Trio—were tailored into 12-foot segments to suit the scale of the room. Suspended from a central junction box, the fixtures provide both direct and indirect lighting, with each component carefully calibrated for its purpose.

The dual lighting zones—up and down—offer flexibility based on the activity taking place. During workouts, downlighting provides focused illumination, while the uplighting creates a softer, more diffused effect, particularly useful for exercises performed lying on one’s back. With just a few adjustments, the lighting can transition to accommodate seminars or group discussions, showcasing how functionality meets adaptability in this space.

The choice of color temperature—3500K—was deliberate, striking a balance between warmth and energy to foster both focus and comfort.

The fixtures also align seamlessly with the center’s brand

identity. Covered in PET felt in a vibrant royal blue, the lighting elements mirror the equipment racks and add a pop of color to the otherwise neutral palette of the walls and floors. This simple yet effective integration of brand aesthetics enhances the overall environment without overwhelming the space.

Seamless Control with Advanced Technology

A standout feature of the project was the use of Acuity Brands’ nLight® DALI networked lighting controls. This cutting-edge lighting control technology simplified the wiring process and ensured maximum functionality.

Unlike traditional 0-10V systems, which can require up to 40 wires (10 sets of 4 wires of similar color) in a single junction box, the DALI system cut the complexity in half. This not only made installation easier but also provided precise dimming capabilities for both the uplighting and downlighting zones.

The system’s user-friendly interface allows staff to adjust lighting levels based on the specific needs of the space, whether for a high-energy training session or a calming seminar. This adaptability enhances the functionality of the lighting, ensuring it supports the diverse activities that take place in the center.

It demonstrates that even small-scale projects can benefit immensely from professional lighting design, offering a model for how similar spaces could be approached.

DALI System’s user-friendly interface allows staff to cuztomize lighting levels based on the needs of the space, whether for a high-energy training session or a calming seminar.

Challenges and Solutions

Like any project, TASH Wellness faced its share of challenges. The most significant issue arose during installation when a wiring error in the final fixture in the DALI chain caused a halfday delay.

Troubleshooting revealed that the DALI wires had been improperly connected, preventing the system from functioning correctly. Despite this setback, the team was able to resolve the issue quickly and ensure the system operated flawlessly thereafter.

Lead times for the standard fixtures also posed a challenge. It took two months to manufacture the lighting elements, which created pressure within the three-month construction timeline. However, careful coordination among the design team, manufacturer, and contractor ensured the project stayed on track.

A Model for Small Spaces

TASH Wellness is a shining example of how even the simplest spaces can benefit from thoughtful lighting design. It demonstrates that great design isn’t reserved for large-scale projects or luxury facilities—it can and should be accessible to spaces of all sizes and budgets. By prioritizing function, aesthetics, and user experience, the team created a space that not only meets the needs of its clients but also elevates the standard for similar facilities.

From the clean, white ceiling to the vibrant blue fixtures, every element of the design was intentional. It’s a space that looks good and works well, proving that lighting can be so much more than an afterthought. As Mor put it, “It’s about thinking through the use of the space, not just putting in high bays and calling it a day.”

TASH Wellness sets a new benchmark for how lighting can transform fitness environments, offering both inspiration and a roadmap for future projects. ■

LIGHTING AN ITALIAN DREAMSCAPE

By

RANDY REID

Designing the lighting for The Giardino del Cielo, or "Garden of the Sky" at Vienza—part of Europa Village in Temecula— presented a unique challenge. The space was envisioned to transport guests to the Italy of centuries past, requiring a delicate balance between classic Italian aesthetics and modern functionality. Lighting designer Kenny Perez, Jr., Senior Project Manager and COO of Visual Concepts Lighting Inc. (VCL), took on the task with an eye for blending tradition with innovation.

Due to the site’s proximity to the Mount Palomar Observatory, the project required a keen understanding of architectural harmony and compliance with strict dark-sky ordinances. The result is a captivating interplay of subtle yet sophisticated lighting that enhances the winery’s romantic ambiance while meeting functional needs.

From the outset, maintaining compliance with dark-sky requirements was paramount. All exterior luminaires were limited to a maximum output of 4,050 lumens to minimize light pollution, while a color temperature of 3000K was chosen to create a warm, inviting atmosphere. These parameters dictated the careful selection and placement of fixtures, ensuring the project adhered to regulations without compromising its visual allure. This challenge underscored the delicate balance between preserving the natural beauty of the Temecula landscape and creating a warm, inviting environment for guests.

Vienza’s architecture is a love letter to Italian heritage, and the lighting design had to reinforce this authenticity. For the event space, Perez partnered with Italian artisans to source custom-made fixtures from Neri Lighting, a premier Italian brand, and SPJ Lighting, which specializes in old-world designs. These fixtures were pivotal in creating the timeless ambiance the client desired.

To emphasize the Italian aesthetic, all visible light sources were integrated seamlessly into the architectural structure. For instance, the SPJ brass low-voltage accent lights were concealed within the building’s framework, ensuring the effect of light was felt but not seen. Hidden lighting eliminated visual clutter, allowing the winery’s rustic elegance to take center stage.

The winery’s colonnade presented unique challenges. Ownership strongly opposed the use of poles or overt lighting systems.

Collaborating with the landscape architect, Perez devised a solution that involved suspending custom SPJ lanterns from the branches of mature oak trees. These lanterns, carefully engineered with frosted lenses and rooftop optics, mimic the warm glow of old-world gas lamps. Their internal structure features a white finish to uniformly reflect light, creating a fully illuminated lantern that evokes a sense of timelessness.

The trees themselves were selected with care to support this design. Initially, younger trees were chosen, but they lacked the structural integrity needed to hold the lanterns, prompting a switch to more mature specimens with larger branch structures. The adjustment ensured both functional lighting and enhanced aesthetic authenticity. It perfectly illustrates the value of a strong relationship with the architect, as Perez successfully persuaded them to select larger, sturdier trees.

Low-voltage lighting was critical in simplifying the permitting process and enhancing the design’s flexibility. Alliance Outdoor Lighting fixtures were utilized for the tree bases and step lights, providing subtle illumination without overpowering the space. At just 350 lumens; the surface-mounted step lights were installed to highlight terraced areas, ensuring guest safety without disrupting the ambiance.

I’m always eager to uncover and highlight best practices when interviewing lighting designers about their projects. This project revealed an invaluable insight: using low-voltage lighting to

overcome tight timelines. The team bypassed the lengthy high-voltage permitting process by opting for low-voltage systems, saving critical time and ensuring the project opened on schedule. This approach met the owner’s deadline and demonstrated the flexibility and efficiency of low-voltage lighting in delivering exceptional results under time constraints. It’s a best practice worth considering for any outdoor project with an accelerated timeline.

Throughout the project, the design evolved to accommodate the owner’s vision. For instance, the catenary lighting system originally planned for the colonnade was replaced with temporary festoon lights due to long lead times on the Neri fixtures. While this interim solution met the immediate need, the team remains committed to installing the authentic catenary system, complete with custom Neri pendants, to enhance the Italian theme further.

Indirect lighting techniques were employed inside the event space to create a soft, inviting glow. Italian-style pendants were paired with hidden accent lights that grazed the brick walls, providing a warm ambiance without harsh glare. Each column was fitted with dual fixtures: one to graze the column’s surface and another to illuminate the seating areas below. This layered approach ensured both aesthetic appeal and functional usability.

A unique feature of the winery’s lighting system is its integration with a misting setup; water lines were run alongside some tree-mounted lighting fixtures to combat the region's intense summer heat with a cooling mist. This unexpected combination of utility and design further elevated the guest experience while preserving the elegance of the lighting scheme.

Though the lighting design is largely complete, ongoing enhancements are planned. To ensure a cohesive look, additional lighting will be added to darker areas, such as the newly expanded event space. Plans also include extending the catenary lighting to span across new shade structures, further enriching the Italian-inspired aesthetic.

The final result is a harmonious blend of traditional Italian charm and modern lighting design. Kenny Perez’s meticulous attention to detail and innovative problem-solving brought the owner’s vision to life. The lighting complements the winery’s architecture and serves as a functional, sustainable solution in a dark-sky environment. For those who visit Vienza, the lighting tells a story of heritage, craftsmanship, and the power of thoughtful design. ■

The Impact of Autonomous Driving on Street Lighting

By CLAUDE ZHU

For over a century, street lighting has served to enhance visibility and create a safer night environment for drivers and pedestrians. Today, autonomous driving is reshaping our transportation, with advanced technologies, safer vehicles, more efficient systems and reliable operation. This will potentially impact the future transportation infrastructure, including street lighting. With the commercialization of AVs, how will the role of the traditional street lighting change?

From rural villages to bustling cities, street lighting plays a crucial role in enhancing road safety. Street lights increase driver visibility, reduce the risk of collisions, and provide pedestrians with a sense of security. Research suggests that proper street lighting can reduce pedestrian crashes by approximately 50%.1

In Australia and New Zealand, street lighting is classified as

Category V (Cat. V) and Category P (Cat. P) lighting, focusing on vehicular- and pedestrian-dominated roads, respectively.

The concept of Cat. V lighting is to illuminate the road surface so that the reflected light, in a preferential direction,2 makes the road surface appear bright, against which an object can be seen by the driver as a silhouette, separated from the background, from an advanced warning distance (Figure 1).

Cat. V lighting levels are determined by the traffic volume and speed limit of the roads; the busier the road, the higher the lighting level, with V1 the highest in the lighting standard AS/ NZS 1158 and descending step by step to V4 (New Zealand) or V5 (Australia).

A summary of AS/NZS 1158 for Cat. V road lighting design parameters is shown in Figure 2, excluding the illuminancerelated components.

Fig. 1 Cat. V lighting concept Graphic courtesy of the author.

Cat. V lighting consumes substantial energy, requires significant maintenance, and contributes significant light pollution and environmental impacts. Its role is expected to be shaken by autonomous driving.

AUTONOMOUS VEHICLE VISION SYSTEM

Autonomous vehicles deploy an array of sensors, including LiDAR (Light Detection and Ranging), radar, cameras, and infrared sensors, to perceive the environment. Unlike human drivers, who rely heavily on light, AVs utilize data from multiple

portions of the EM spectrum to detect obstacles, lane markings, and other vehicles, even in low-light conditions (Figure 3).

• LiDAR uses laser pulses to create detailed 3D maps, enabling AVs to “see” objects regardless of lighting conditions.

• Radar provides information about the speed and position of objects and can operate in poor weather conditions.

• Infrared sensors allow for the detection of heat

Thanks to the sophisticated systems, AVs are designed to “see” better than human drivers can at night, minimizing the need for traditional street lighting.

Figure

signatures, such as those from pedestrians and animals, making them ideal for night driving.

• Cameras, while affected by lighting, provide detailed imagery that other sensors may not capture. Many AVs employ cameras with night vision capabilities.

Thanks to the sophisticated systems, AVs are designed to “see” better than human drivers can at night, minimizing the need for traditional street lighting. According to World Health Organisation (WHO) reports, approximately 1.3 million people lose their lives on the world’s roads each year.5 Widespread adoption of autonomous vehicles could lead to a 90% reduction in vehicle crashes.6

POTENTIAL BENEFITS OF REDUCING STREET LIGHTING

As autonomous driving continues to evolve, the required lighting levels on vehicular roads such as arterials and collectors is expected to drop. In the future, when the self-driving systems mature, only minimal lighting will be required for these scenarios.

Together with the smart lighting technologies, substantial energy savings and reduced CO2 emissions could be achieved. Less urban light pollution also helps to restore the natural night

sky and preserve the ecological system.

Moreover, municipalities bear high costs for the procurement, installation, and maintenance of street lighting. Autonomous driving could reduce these expenses, freeing up resources for other projects.

CHALLENGES

Cities need to incorporate AV-friendly features, such as dedicated lanes, charging stations, and smart lighting systems that work in sync with AVs.

Vehicular road-based street lighting may not become obsolete in the near future. First, during the transition to fully autonomous driving, non-AVs will still rely on street lighting. It’s unlikely that all vehicles will be autonomous in the short term, especially in rural or economically disadvantaged areas where the transition could take decades.

Second, while AV sensors are intelligent, they are not infallible. Adverse weather conditions like heavy fog, snow, and rain can impair sensors. Street lighting could offer an additional layer of safety in case of emergency.

Therefore, urban planners are likely to maintain some level of

Figure 4. Night sky at Lake Tekapo, New Zealand Credit: Aoraki Mackenzie, International Dark Sky Reserve

street lighting to ensure safety and accessibility for all residents for the foreseeable future.

SMART LIGHTING

Harnessing the power of dimmable LED lights, motion sensors, and connectivity features, smart lighting systems could reduce light levels in areas where AVs are prevalent but highlight key areas when human drivers or pedestrians are present.

In addition, AVs could communicate with smart streetlights to request lighting as needed, ensuring that the streets are only lit when necessary. Hybrid solutions allow for a gradual transition from traditional street lighting to more AV-compatible systems, ensuring safety and efficiency for all road users.

CONCLUSION

While autonomous vehicles have the potential to operate effectively without street lighting, it’s unlikely that vehicular road-based lighting will become entirely redundant. Pedestrian safety, non-autonomous vehicles, and sensor limitations suggest that some form of street lighting will remain essential. However, smart lighting offers a promising compromise, enabling municipalities to reduce energy consumption and light pollution while maintaining safety for all road users.

In the future, autonomous driving may inspire a re-evaluation of

street lighting’s role in urban infrastructure, but it is unlikely to eliminate the need for it altogether.

As technologies evolve, cities can explore innovative lighting solutions that balance the needs of both AVs and traditional road users, paving the way for safer, more efficient, and environmentally friendly urban spaces.■

Antonia Peón-Veiga’s Drawing Light

Antonia Peón-Veiga, a lighting designer and architect, has transformed her passion for visualizing light into a thoughtprovoking book, Drawing Light. Initially conceived as her thesis during her master’s program at Parsons School of Design, the project has evolved into a published work that explores innovative ways to represent light graphically.

The Genesis of Drawing Light

Antonia’s journey began with her architecture studies in Chile. After earning her degree, she moved to New York to complete a Master’s in Lighting Design at Parsons from 2008 to 2010. Her thesis, which earned the Parsons Thesis Prize, served as the foundation for her book. The recognition didn’t end there— Antonia was also awarded the prestigious Richard Kelly Grant to continue her research on translating luminous phenomena into visual tools.

“I always wanted the thesis to be more than a single copy in the Parsons library,” Antonia shared. “I wanted it to be a shared document—a resource for lighting designers and architects alike.”

From Idea to Publication

After returning to Chile, Antonia pursued her vision to publish the thesis independently. However, a friend suggested she collaborate with a publisher to reach a broader audience. Enter ARQ, a publisher specializing in architecture-focused academic works. Over two years, Antonia worked with the ARQ team to refine her thesis into a cohesive book, complete with new

chapters and interviews with prominent lighting designers like Douglas Leonard.

The book isn’t just a reproduction of her thesis—it’s an expansion. Antonia included an appendix and fresh illustrations, exploring the intersection of light, space, and time.

A Deep Dive into the Case Studies

The book’s core lies in its four case studies, which analyze methods of representing light through the lens of botanical illustration, stage design, Cinemetrics, and music composition. Each chapter borrows the structural framework of an existing illustration or diagram, deconstructs it, and repurposes it to visualize lighting ideas.

For example, Antonia’s analysis of botanical illustrations reveals how these drawings convey the passage of time and overlay layers of information. She used this structure to represent light and its interplay with materials and spatial elements.

Similarly, Antonia drew inspiration from stage design and music composition. One striking example is her adaptation of a graphic score by composer Iannis Xenakis. In his original work, Xenakis used color-coded lines to represent musical instruments and their intensity over time. Antonia transformed this into a lighting diagram, replacing instruments with light fixtures and intensity curves with scenes of light transitions in an auditorium.

“These structures offer tools to communicate lighting concepts that are often intangible or complex,” she explained.

A Journey from Thesis to Book

“It’s about translating light’s interplay with time and space into something tangible.”

Academic and Professional Applications

While Drawing Light could easily serve as a textbook for lighting design programs, Antonia hopes it will also inspire professionals to think beyond conventional representation techniques. The book challenges designers to use drawings not just as presentations but as tools for ideation and exploration.

“I want this book to open up discussions about how we represent light graphically,” Antonia noted. “It’s not just about creating visually pleasing drawings—it’s about pushing boundaries and enhancing our understanding of light’s complexities.”

The Challenge of Distribution

The physical copy of Drawing Light is currently available through ARQ, and an online PDF version is also accessible. The PDF is part of ARQ+, an online platform featuring a vast collection of books and magazines. The annual subscription to ARQ+ is $30.00 for regular users and $15.00 for students. While Amazon might seem like an obvious choice for distribution, Antonia opted for a publisher closely tied to architecture and academia.

“Amazon isn’t as prominent in Chile as it is elsewhere,” she explained. “By working with ARQ, I’m able to position the book in schools and universities where lighting design is studied.”

The Importance of Collaboration

Antonia credits much of her success to her education at Parsons and her professional experiences. After completing her master’s, she spent two years working with Suzan Tillotson, a globally renowned lighting designer. Though Antonia eventually returned to Chile to fulfill a scholarship requirement, she maintains a close relationship with Tillotson and other mentors.

Reflecting on her time at Parsons, Antonia expressed gratitude for professors like Craig Bernecker and, more recently, Glenn Shrum, who invited her to present her work at a lecture series. These

connections have been instrumental in her growth as a designer and author.

Looking Ahead

Antonia continues to push the boundaries of lighting design. She’s currently exploring performance lighting, collaborating with her sister, a choreographer, to create dynamic stage environments.

When asked about her long-term goals, she said, “I hope this book sparks new ways of thinking about light. I want it to be a starting point for others to develop their own tools and methods for representing lighting ideas.”

For lighting designers, architects, and anyone fascinated by the art of light, Antonia Peón-Veiga’s Drawing Light offers an invaluable resource that combines academic rigor with creative exploration. It’s a testament to her passion for lighting design and her commitment to sharing knowledge with the global design community.

Elegant arches and portals inspired by traditional Papuan architecture create a dynamic and modern retail experience.

Pastries, cakes, and savory items are showcased under carefully calibrated lighting for maximum appeal.

Located in Jayapura, at the furthest end of Indonesia, SAGA Bakery is an architecturally significant bakery experience that elevates the retail landscape in the city while retaining the traditional Papuan theme. Designed by Darren Pirono and Jefferson Frans Tan of Jakarta-based Upper Room Collaborative Studio, the bakery transcends traditional concepts, creating a vibrant experience and social gathering space, while displaying a wide assortment of stylishly and dramatically presented freshly baked products.

A family-owned business with three generations of history in Jayapura, the owners sought to rebrand their flagship bakery, to modernize their establishment and establish it as an icon for the city. Jayapura, with a population of 415,000, is the capital of the province of Papua, bordering the Arafura Sea. SAGA Bakery occupies a prime location on the first floor of a shopping mall, positioned by the structure’s entrance. The glass façade, which offers a view of the east and to a popular neighboring restaurant, making it a prominent landmark for customers entering or driving past the mall, captures full sunlight along the entire facade.

The design concept is rooted in arches and portals inspired by classical regional architectural buildings, translated into a modern, sleek, colorful palette to commemorate the company's rebranding. The arches, portal shapes, and proportions are derived from the intersection of projected lines based on the original store's layout and structural elements. It also factors in the projected line towards the facade to take advantage of the maximum level of sun without allowing direct sunlight to enter, which can damage the Bakery's products.

The space is zoned using portals that serve various functions, such as displays, sales, and transitions, creating an intimate and navigable environment for visitors. Solid, transparent,

and translucent portals direct customer flows and produce sequential space. Customers view the collection of displays as an introduction, becoming familiar with the Bakery's extensive product selections. They then arrive at the main display area, where various pastries, cakes, and savory snacks are artistically presented.

SAGA Bakery showcases a vibrant, bright red brick that aligns with its brand identity, paired with lighter wood and stone textures that highlight different spaces to achieve a harmonious visual effect. The project involved a challenge to integrate rigid materials to align with the fluid and flexible arches and portal shapes, which are responsible for creating the distinctive retail interior design.

Due to the project’s complex assembly of custom elements, the design team recognized the need for more experienced labor and material resources than was available in the Jayapura region. Darren Pirono and his colleagues oversaw the bakery's intricate designs that were produced on full scale in Jakarta. They were then packed and shipped in container boxes and assembled like Lego pieces at the Jayapura site in four weeks.

Darren Pirono, director of architecture and interior design for Upper Room Collaborative Studio, led his firm’s team in the development of the lighting program for SAGA Bakery, integrated the expertise of X3M Architects, and coordinated with the design-build firm to create a comprehensive and sustainable lighting program for the 1,475-sq-ft space, Here, for Designing Lighting, Pirono describes the design process and implementation of the overall design concept for the selling areas and the lighting program for ambient and accent light illumination that gives the store its distinctive retail presence.

“We conducted an in-depth analysis of the site, strategically

utilizing the expansive full-length and height glass facade to optimize the availability of natural light. This approach aimed at significantly reducing electricity consumption during daytime hours. We observed how sunlight shifts throughout the day to identify specific areas requiring additional artificial lighting and determine the best times to activate these lights.

“It was important to avoid illuminating the entire space simultaneously to minimize energy usage until evening when full artificial lighting is necessary. Our concept for the SAGA Bakery, with its 19-ft-high ceiling, drew inspiration from classical architecture, and we examined how modern lighting can enhance the beauty of these historic structures. We primarily employed indirect lighting on shelves, allowing light to wash over the arches and portal areas gently.

“The typical display arches span from four to six feet; the most expanded-span arches are located in the back near the golden glass wall, measuring approximately eight feet. This technique not only emphasizes the materials and curves of these architectural features but also creates a warm and inviting atmosphere. In the Main area—specifically the Foyer, Cakes, and Display area—we arranged the lighting in accordance with shelf placement. This strategic positioning ensures that light does not cast harsh shadows on the products, instead softly highlighting them to attract customer attention. Under-shelf lighting, as well as the vertical lighting and the lighting on the back of the shelf as indirect lighting for the brick portal area,

use LED Strip 2835 60LED from HILed, each 16.4-ft meters long, 3000˚K warm white. They are contained within an extruded aluminum frame and covered with a white acrylic top to diffuse the light.

“We opted for lower-wattage lighting and a warm white color to establish a slightly dimmed ambiance that fosters a relaxed and comfortable environment, encouraging customers to move leisurely. This psychological effect enhances their shopping experience and significantly increases their chances of purchasing additional items.

“Philips Essential LED MR16 4.5 watts in 3000˚K warm white provides illumination for the overhead recessed lighting. Encased in a double-hole aluminum light box, they were custom-painted with heat and electronic safe paint to match the interior color.

Since its opening in November, 2023, SAGA Bakery has experienced a 50 percent increase in daily profits.

Upper Room Collaborative Studio, established in 2020, provides comprehensive design and build services in architecture and interior design. In 2023, the firm received the A' Design Award in the Interior Space and Exhibition Design category for 2022-2023 in Milan, Italy, for their 'Tranquil by the Sea Regatta Residence' project. SAGA Bakery is the first interior design project in Papua to be shortlisted for the 2024 World Architecture Festival. ■

2024 IECC and Lighting Controls

Adopted by states and other jurisdictions, commercial building energy codes regulate the energy-efficient design of buildings, with the majority based on the International Energy Conservation Code (IECC), a model code.

In August 2024, the International Code Council published the 2024 version of the IECC, which has been updated every three years since 2000. As with previous iterations of the IECC, this new version reduces lighting power allowances, expands mandatory controls requirements, and issues clarifications.

This article starts with some background about commercial building energy codes and then describes the major lighting control requirements in the 2024 IECC, highlighting significant changes from the 2021 version. For greater specificity regarding requirements and exceptions, consult the IECC. For ultimate interpretation, consult the authority having jurisdiction.

Codes and standards

Energy codes may be adopted for residential or commercial buildings and at various levels of government including Federal, state, and local jurisdictions. At the state level, a majority have adopted codes based on the IECC; others base it on the ANSI/ ASHRAE/IES 90.1 energy standard, developed their own code, or have no statewide code. As both the IECC and 90.1 are updated every three years, this presents a significant variety of energy codes across jurisdictions and a need to keep abreast of code developments. Note the IECC recognizes 90.1 as an alternative compliance standard, presenting 90.1 compliance as an option.

In an effort to promote energy savings, the Department of Energy (DOE) recognizes 90.1 as the national energy reference standard. Currently, the DOE recognizes the 2019 version as being in effect. In March 2024, the DOE determined the 2022 version saves energy compared to the 2019 version and now requires all states to adopt it or an equivalent by 2026 in order to receive enforcement funding, or justify why they cannot comply.

The figure opposite shows commercial building energy code

adoption in the United States as of September 2024, based on analysis by the DOE, which established categories of energy efficiency based on different version of 90.1 or equivalence to these versions. While the map indicates a significant lag in complying with the DOE rulings, steady progress has been made to adopt more stringent codes and energy efficiency.

Scope of the 2024 IECC

The 2024 IECC applies to various energy-using systems (including electric lighting) installed in building new

construction, additions, and alterations, including electric lighting. The lighting section (C405) contains prescriptive and mandatory provisions focused on prescriptive lighting power allowances, mandatory lighting controls, and functional testing of lighting controls, with various exceptions.

The 2021 version included the addition of daylight-responsive lighting control for secondary daylight zones, automatic power receptacle control, parking garage lighting control, and corridor lighting control. In the 2024 version, major changes include manual continuous dimming being specifically required in a range of space types, parameters for implementing an enhanced energy efficiency option for demand-responsive lighting control, and removal of the luminaire-level lighting control (LLLC) compliance path.

Also new to the 2024 version, for alterations, the exception was removed for projects involving replacement of less than 10 percent of interior luminaires (Section C503.5). For exterior lighting, a threshold of 400W was added. If wattage is increased by 400W, the IECC’s lighting power allowances apply. If the total wattage of new or replacement luminaires exceeds 400W, the exterior lighting control and related functional testing requirements apply, with a significant exemption for individual luminaires smaller than 50W that pass functional tests for automatic shutoff based on daylight.

Lighting control

Conceptually, the 2024 IECC aims to minimize energy consumption by automatically reducing or turning OFF lighting when it is not being used based on three inputs: occupancy, a time event, or ambient light level. Additionally, various manual controls are required for occupant convenience and additional energy savings with dimming, and zoning restrictions ensure

independent control of lighting where needed. Functional testing requirements ensure the lighting control installation is vetted and supported by construction documents.

New to the 2024 IECC, the LLLC compliance path has been removed. Starting with the 2018 version, the IECC began offering two paths for interior lighting controls compliance: 1) a discrete approach that satisfies all the applicable requirements, and 2) a more direct approach of luminaire-level lighting controls along with occupant sensors, specific application controls, and manual controls. In the 2024 IECC, LLLC returns to being a compliance option rather than a formalized path.

Occupant sensing (C405.2.1)

Occupant sensors can be used where appropriate to satisfy requirements for interior automatic shutoff, but they are specifically required in a range of spaces. These are usually smaller, enclosed spaces such as classrooms and private offices but also include larger spaces such as warehouses and open offices, which can be divided into smaller zones with dedicated occupant sensor control.

New to the IECC in the 2024 version, computer rooms (data center), medical supply rooms (healthcare facilities), laundry/ washing areas, and telemedicine rooms (healthcare facilities) have been added to the list of spaces requiring occupant sensor controls.

Where occupant sensors are installed, a manual Off control device is required, which may be remote or integrated with the occupant sensor. Otherwise, the sensor must turn the lights Off within 20 minutes of the space being vacated and feature manual-On or auto-On-to-maximum-50-percent-power operation. Full auto-On with no manual control is allowed in

some applications, such as corridors and interior parking areas.

The 2024 IECC identifies three special applications for occupant sensors, with particular requirements:

Warehouse storage areas: The sensor must reduce lighting power by no more than 50 percent within 20 minutes of the area being vacated. Lighting in each aisle must be controlled independently. Lights that are not turned Off by occupant sensors must be controlled via a time-switch enacting scheduling. A manual control must be provided that enables occupants to turn the lighting Off.

Open Offices: When a sensor in a control zone detects occupancy, it may turn the lights On to full. When this happens, the lights in unoccupied zones in the open office may stay Off or turn On to no more than 20 percent full power.

Within 20 minutes of a control zone being vacated, the lights must turn Off or uniformly reduce to no more than 20 percent of full power. When all occupants have vacated all zones, the control system must turn all general lighting Off, or a timeswitch may be assigned for this.

Corridors: Unless the corridor is lighted with the bare amount of illumination required for safety, lighting power must be uniformly reduced by no more than 50 percent within 20 minutes of the space becoming unoccupied.

Time-switch controls (C405.2.2)

Where occupant sensors are not installed, time-switch controls must be installed and programmed to automatically turn the lights Off when the space is predictably unoccupied based on a schedule, with notable exceptions.

The control must feature a minimum seven-day clock, backup capability in the event of power interruption, and “holiday” programming. New to the 2024 IECC, for spaces where schedules aren’t available, the control system must be programmed to a schedule that turns the lights Off at least 12 hours per day.

Users must be given override capability via a manual control device that is limited in zoning to 5,000 sq.ft. and keeps the lights On for no longer than two hours. Manual controls must be located so they are readily accessible to occupants and either enable the lights to be visible or otherwise indicate the area and status of the lights. In certain large facilities such as mall concourses and sports arenas, the override time may be longer (if the override is a captive key device) and the control area may be up to 20,000 sq.ft.

Dimming controls (C405.2.3)

Previously titled “light reduction controls,” this section has been thoroughly revised in the 2024 IECC. Eliminating bilevel switching as an option, this version requires continuous dimming controls for general lighting in a list of spaces from classrooms to lobbies to offices (with an exception for lighting controlled by special application controls, which we’ll cover in detail later in this article).

Dimming controls must be manual unless high-end trim lighting control is being implemented for the lighting. The lights must be continuously dimmable from full output to 10 percent of full power or lower, plus Off. Again, manual controls must be located such they are readily accessible to occupants and either

enable the lights to be visible or otherwise indicate the area and status of the lights.

Daylight-responsive controls (C405.2.4)

The 2024 IECC requires that general lighting in daylight zones feature daylight-responsive controls that independently control the lighting, with exceptions. The IECC defines the dimensions of these daylight zones (primary and secondary) based on whether they are sidelit (adjacent to vertical fenestration such as windows) or toplit (under fenestration such as skylights).

Daylight-responsive controls are required in daylight zones as defined by the code if the general lighting reaches a wattage threshold, which the 2024 IECC reduced from the 2021 version for primary sidelit and toplit zones. If the space has primary sidelit and/or toplit daylight zones containing more than 75W of general lighting, daylight-responsive control is required. If the total wattage of general lighting in primary and secondary sidelit daylight zones combined is more than 150W, again, control is required. The lighting in sidelit and toplit zones must be controlled independently, as must lighting in primary and secondary sidelit zones. In the 2024 version of the IECC, the calculated exception to daylight-responsive controls in trade for lowering the lighting power allowance was removed, and an exception added for enclosed office spaces smaller than 250 sq.ft.

Controls must be automatic and provide continuous dimming down to at most 15 percent of full light output and be capable of turning the lights Off. Controls must be configured so they can be calibrated within the space, with the calibration means readily accessible. In warehouse storage areas and corridors where occupant sensing reduces lighting, daylight-responsive controls may reduce power further but not raise it above the level set by the occupant sensor.

Special applications (C405.2.5)

The 2024 IECC designates control requirements for special applications such as display and accent lighting and supplemental task lighting. These luminaires must be controlled by either an occupant sensor or time-switch control for automatic shutoff, plus a manual control enabling them to be controlled separately from the general lighting.

Lighting for nonvisual applications such as plant growth must be served by an independent time-switch control. However, note that Section C405.4 in the 2024 IECC calls out horticultural lighting and states that the luminaires in greenhouses must be controlled by a device that turns Off luminaires in response to daylight.

Interior parking garage lighting controls

(C405.2.9)

The 2024 IECC requires lighting controls in interior parking garages. Interior parking garage lighting must be controlled by either an occupant sensor or a time-switch control. Additionally, lighting power must be automatically reduced based on occupancy with a time delay of 20 minutes and a control zone limited to a maximum of 3,600 sq.ft. At entrances and exits where lighting is provided for visual adaptation between indoor and outdoor brightness levels, this lighting must be reduced by at least 50 percent between sunset to sunrise.

Sleeping and dwelling unit controls (C405.2.10)

The 2024 IECC created a new special section for sleeping

and dwelling units and identified all control requirements and exceptions there.

In sleeping units and dwelling units in hotels, motels, and vacation timeshare properties, at least two 125V 15- and 20-amp switched receptacles must be provided in each room aside from bathrooms, kitchens, foyers, hallways, and closets. Lighting controls must be provided that automatically turn all lights and switched receptacles Off within 20 minutes of the unit being vacated. Automatic shutoff is not required, however, if captive key override control is used to control lights and receptacles in units that have five or fewer permanently installed lights and switched receptacles.

In sleeping units located in congregate living facilities, an appropriately marked manual control must be installed by the entrance that turns Off all lights and switched receptacles aside from bathroom and kitchen lighting. In bathrooms, an occupant sensor must be installed for automatic shutoff within 20 minutes of vacancy.

Automatic receptacle controls (C405.12)

The 2024 version of the IECC contains automatic receptacle (plug load) control requirements. Specifically, at least 50 percent of all permanently installed 125V, 15A and 20A receptacles installed in certain applications such as enclosed offices, workstations, and classrooms must be controlled. At least 25 percent of branch circuit feeders installed for modular furniture not shown on the plans must be controlled.

The control function may be based on split-controlled receptacles (top controlled) or separate controlled receptacles must be installed within a foot of each uncontrolled receptacle. All controlled receptacles must be marked per NFPA 70 and uniformly distributed.

The receptacles may be controlled either on a scheduled basis using a time-switch, via an occupant sensor with a 20-minute time delay, or via a signal from another control or alarm system.

Exterior lighting controls (C405.2.7)

With exceptions, exterior lighting must be turned Off when sufficient daylight is present or based on a schedule.

Building façade and landscape lighting must be automatically turned Off during the night when it is no longer needed, within set times. All other exterior lighting—typically operating dusk to dawn—must be reduced by at least 50 percent during the night based on time or occupancy.

Additional energy efficiency requirements (C406)

Buildings complying with the 2024 IECC must enhance energy efficiency by acquiring credits for implementing various stretch energy efficiency options listed on a table with applicable credits. First introduced in the 2021 IECC, this section has been dramatically revised and expanded to delineate requirements by building size. For lighting, options include energy monitoring, high-end trim lighting controls, occupant sensors installed in more applications and with a 10-minute time delay, reduced lighting power, demand-responsive lighting controls, and automated shading. Note that the credit for enhanced digital lighting controls has been removed.

Demand-responsive lighting controls (C405.2.8)

Demand-responsive lighting controls are covered as an enhanced energy efficiency option in C406 and also in Appendix CI103.1, which requires at least 75 percent of the interior floor area in certain building occupancy categories to have demand-responsive lighting controls. This appendix is not mandatory and is subject to specific adoption as ordinance by the jurisdiction to be effective as a requirement.

In either scenario, if demand-responsive lighting controls are installed, they must be capable of reducing the output of controlled lighting down to 80 percent or less of either full power or full output after receiving a demand response signal from a certified virtual end node (VEN). If high-end trim is implemented, the trim level is considered “full power” or “full output.” The lights should be continuously dimmed over a period up to 15 minutes to reach the demand response level. After the demand response event ends, the controlled lighting must return to normal operation.

Functional testing and documentation (C408.3)

The 2024 IECC’s Section C408 requires project commissioning to ensure all installed building systems operate as specified. This includes functional testing for lighting controls and automatic receptacle controls as well as certain documentation.

Specific functional testing is indicated for different control types: occupant sensors (lighting and automatic receptacles), time-switch controls (lighting and automatic receptacles), and daylight-responsive controls. New to the 2024 IECC, this section now also includes functional testing requirements for highend trim controls and demand-responsive lighting controls if installed.

At the conclusion of the project, in addition to documentation provided by the functional testing party that the installed controls meet or exceed specified performance criteria, the owner must be provided certain documentation about the lighting and control system so that they can maintain it.

Documentation requirements include a lighting control narrative (Control Intent Narrative) with recommended setpoints, operating and maintenance manuals, functional testing report, submittal data indicating all selected options for lighting and controls, a schedule for inspecting and recalibrating lighting controls, and more.

2024 IECC decoded

Commercial building energy codes continue to become increasingly stringent in regard to lighting and controls while evolving with technological change, and the 2024 version of the IECC is no exception.

In the future, commercial building energy codes may evolve toward a focus on energy consumption and decarbonization rather than initial design power and control capability. In the meantime, the 2024 IECC is likely to be adopted by jurisdictions and put to use.

Lighting practitioners in jurisdictions likely to implement the 2024 version of the IECC should start to become familiar with its requirements, as there are some significant changes, particularly in regard to lighting and controls.

Residential Lighting Design

When Editor Randy Reid contacted my co-worker, Stacie Dinwiddy, and me about taking the residential lighting design baton from contributor David Warfel, I started writing on one topic, then another, and it hit me this is hard it has become extremely difficult to design, specify, and implement a great lighting design.

I recently visited NASA in Houston and toured the Saturn V rocket exhibit. While it’s not rocket science, our designs involve tens or hundreds of thousands of decisions and can look similarly daunting. In most professions, the more you do it, the easier it gets.

For those of you who are relatively new to the world of lighting design, you’re probably wondering why the more you learn, the harder it gets.

Every residential lighting designer fights a similar war as our work intersects with every other decision maker on a project. We battle the schedule, the budget and the clashes. We battle HOAs and jurisdictions with their ever-changing codes and unpredictable reviews. We battle the acceleration of technology where unique combinations of components need to play well together. Like a fingerprint, each project has its own combination of electronics in diodes, drivers, dimmers and breakers that could be made in different countries at different points in time.

An abridged checklist used to specify a downlight

As we kick off a design, we review the architectural, interior and landscape drawings, renderings and models. We review Pinterest boards and adjacent information provided by the project’s stakeholders.

We then have meetings to set the goals for each project. Is the goal to ensure there are no scary dark corners, or is it to provide appropriate lighting for sitting around a fireplace and watching the snowfall on Christmas Eve? Is the goal to provide appropriate lighting for hosting large fundraisers, or is it to light a museum-grade art collection? We juggle sometimes-opposing opinions of designers, architects, husbands and wives.

Regardless, our goal is always to tailor our design to the project.

We have more questions as we get into the design. What do the vertical surfaces look like? Which ones will have art or built-ins? Will the finishes be dark or light; matte or shiny; flat or textured? How will the room be used and furnished? Will art and furniture be fixed, or do we need to design for flexibility? Is this space public or private? Is the ceiling flat, stepped, sloped, barreled, trayed, vaulted, or is it made of a thin layer of fabric suspended below a void space? Are there decorative fixtures, and if so, what are they functional for? The list goes on…

We go through a similar process for each space as well as the exterior and landscape.

We use the knowledge gained in this phase to lay out the first light in CAD or Revit, then the second and third. Then, we step back to look at alignments with each other and with the architecture. We lay out the next and the next, constantly shuffling the layout to accomplish the necessary function while keeping a sense of order in the ceiling.

To look at how difficult this has become, I’ll break down some of what it takes just to specify a downlight.

In this initial phase, we’ve determined the aesthetic of any recessed lights we may use. Say it’s going to be a square bevel with an open aperture, a satin nickel trim to fade into the greyish wood ceiling, and a black reflector to obscure the view into the guts of the housing. We then decide it’s going to be flangeless and need to verify this manufacturer’s light will work and how much the thick ceiling will limit the adjustability. We then specify a collar to adapt to this thick ceiling. Depending on the manufacturer, the extension collar could be integral to the housing, or there may be an extended part of the trim.

If the client desires a dynamic lighting technology, we can kiss the narrow spot goodbye. If narrow spots are the driving factor, as they might be for someone with an extensive sculpture collection, so much for dynamic lighting. If the space is a home theater, we may want very low and smooth dimmability, so we will choose that appropriate driver. If a client is more focused on budget, we may go with a static color and basic driver that’s not fade-to-black.

It isn’t uncommon to specify 10 or 20 different types of recessed lights to adapt to varied conditions in a home.

Once we’ve survived the brain damage inflicted by specifying the downlights, we go through a similar checklist for different types of linear lights, steplights, in-floor uplights, light panels, monopoints, track systems, path lights and landscape bullets.

We finish up by layering controls information into the plans and issue a pricing set. When the pricing comes back, the client’s either okay with it…or not. If all is approved, we move into CDs, but if not, we guide the design through a VE process, attempting to keep the original intent as much as the budget will allow. Then, we issue CDs, and we have designed the perfect plan.

For residential projects, when CDs are issued, that’s when things really start changing. We spend the construction phase continuously adapting to new information from “others.” With each iteration, we’re trying to make Plan B appear as if it was Plan A.

The home is furnished, and the homeowners have moved in. Inevitably, we get the call that the kitchen feels dark or the bedroom reading lights are shining in the homeowner’s eyes. It’s time to finish.

We show up with our bag of tricks and work with the contractors to perform the final adjustments. In the glass houses we design today, our work hours resemble those of a vampire who moonlights with a day-job.

At the site, we find the spare optics we specified were thrown away by a laborer, and the electrician shows up, half-staffed and without the ladder we need to get 100% complete. We ascend scaffolding only to find the trims have been plastered into the ceiling, or screws which hold the ceiling in place are protruding into the aiming mechanism, prohibiting us from spinning our light in the required direction.

In today’s maddening world, even with mock-ups and meticulous planning, the color of light leaving a chandelier appears different than the color of light emitting from the coves. These are both different than the color of light leaving the table lamps, downlights, steplights and wall sconces.

After swimming upstream through all of these obstacles, we step back to view the finished product. Small wins are everywhere. The Picasso pops. The stone wall’s texture is elegantly revealed. The backlit shelves look sexy, and someone sitting in the library can read a book without feeling like an actor on stage.

For lighting designers, the project’s long days and nights fade as we share a glass of wine with the homeowner and celebrate the 99.9% of things we happened to get right….before waking up the next day and heading back to fight another battle with new knowledge gained the night before. ■

TRANSFORMING WELLNESS WITH SKYVIEW ™

BIOS Lighting’s Leap to Finished Products

During the IALD Conference in October, held in Rancho Bernardo, CA, I had the opportunity to visit BIOS Lighting’s headquarters in nearby Carlsbad. There, I met Eric Schafer, Director of Engineering, and experienced firsthand the revolutionary SKYVIEW™ lighting system. BIOS has redefined human-centric lighting by focusing on circadian wellness through innovative engineering and thoughtful design.

This innovative system incorporates an improved spectrum that mimics the natural dynamics of daylight. By integrating spatial separation between biologically relevant blue light and warmer tones, SKYVIEW™ mirrors natural outdoor conditions. Blue light is positioned above, and warmer tones are directed below, aligning with human photoreceptors to optimize circadian synchronization.

Our conversation took place directly under the SKYVIEW™ lights, which hang from the ceiling in a three-dimensional bubble-like form. Schafer explained that the unusual form of the fixture helps to get the light to the back of the eye.

He demonstrated the system’s impact with a striking comparison. After 20 minutes of discussion under SKYVIEW™, he switched to traditional LED panel lights. The difference was dramatic. The vivid colors, textures, and overall visual clarity under SKYVIEW™ were unmatched. I was blown away by how dull and grey everything looked under the panel lights—I encouraged them to quickly go back to the SKYVIEW™.

The SKYVIEW™ system stands apart with bold claims backed by interventional clinical research. Users report experiencing significant benefits within just days, including:

• 12% boost in productivity and performance

• 90% improvement in focus and attention

By RANDY REID

• 78% increased motivation and a better mood

• Feeling as though they gained an additional three hours of sleep

While these numbers might seem hard to believe, seeing is believing. After experiencing this light in person and contrasting to the LED panel lights, the claims make sense. The impact of SKYVIEW™ truly comes to life in a side-by-side comparison.

The system is designed to bring the essence of being outside on a blue sky day. And I really did feel the difference being under the lights.

Their approach is the only one to meet the IES’ new wellness recommendation (RP-46-23) of 250 m-EDI with such comfort. The Gradient Circadian Optimization (GCO) technology, a gradient from a blue-sky colored light to a warm sunlight color, allows them to achieve this feat. And, having witnessed it, it is beautiful. It makes a big statement for wellness, and a picture doesn't do it justice.

BIOS has traditionally been known as an OEM, focused on selling components to lighting manufacturers. However, SKYVIEW™ represents a significant shift for the company. Robert Soler explained, “SKYVIEW™ is a new product with a new go-to-market strategy. We will now have our own network of agents selling completed products.”

Soler also emphasized that BIOS would continue to sell components, maintaining the approach they have successfully used in the past.

GUIDING LIGHTS

The Value of Mentorship with Amber Hepner

For Amber Hepner, mentorship isn’t just an industry buzzword; it’s an extension of her own journey—one marked by curiosity, challenges, and transformative guidance. When Amber first stepped into the world of lighting from her background in architecture, she didn’t have all the answers. But she did have the benefit of mentors who believed in her potential, encouraged her questions, and celebrated her growth. Now, with over 16 years at Lam Partners, Amber carries forward this spirit of mentorship, cultivating a supportive environment where learning and collaboration are central to success.

A Path Shaped by Curiosity

Amber’s journey into lighting design began with a willingness to explore the unfamiliar. Growing up both on the East Coast and in Colorado, she was inspired by her father, a craftsman in the construction industry. Her young introduction to technical drawings and a fascination with the use of space and design led her to pursue a master's degree in architecture at Wentworth Institute of Technology in Boston. However, after working in residential design for a time, Amber found herself craving more diversity in her work. “It wasn’t the original plan,” she says, “but I started to realize I wasn’t done learning.”

That realization led her to Lam Partners, a firm renowned for its emphasis on collaboration and technical excellence. It wasn’t a direct leap—Amber recalls being upfront during her interview about her limited exposure to lighting design. But what she lacked in technical know-how, she made up for with a deep

understanding and interest in architectural design—and a hunger to learn. “I really came to love lighting as an integral piece of the architectural design puzzle. The way that lighting shapes the human experience in both unpredictable and beautiful ways really brought all of what I loved about design together.”

Amber attributes much of her success at Lam to the strong mentorship she received during her early years there. Among her mentors was Robert Osten, one of the founding principals. His teaching style combined patience, curiosity, and a sense of empowerment. “Bob had this way of creating a space where it was okay to ask questions and even make mistakes,” Amber recalls. “He didn’t just tell me what to do—he made me think critically about why we were doing it.”

This approach, Amber says, gave her the confidence to embrace the complexities of lighting design. Whether it was determining light levels intuitively or working through project constraints, Bob’s mentorship instilled a sense of trust in her own judgment. “He made me feel that my perspective and ideas mattered,” she says. “That’s a gift I try to pass on to others.” It also fostered her belief in the importance of creating a space where learning and collaboration thrive.

Building a Collaborative Culture

As Amber grew in her career, she began to take on leadership roles in the firm. One of her proudest contributions has been the development of Lam Partners’ internship program. Over the years, Amber has worked to create an experience that balances technical training with real-world project exposure. “I want interns to feel like they’re part of the team,” she says. “It’s not about giving them busywork; it’s about helping them see how their contributions fit into the bigger picture.”

Recognizing the need for a structured approach to training, she formalized the onboarding processes for interns, which now extend to all new hires at Lam. "I want to make sure their learning experience is as immersive and supportive as it was for me," she explains. From developing detailed training materials to initiating introductions to the team, Amber has worked to create a comprehensive and inclusive framework. These introductions foster relationships that encourage open dialogue and collaboration. "It’s about cultivating a sense of belonging,"

she says. "When people feel valued and supported, they’re more likely to thrive."

Beyond formal programs, Amber’s influence extends to the broader culture at Lam Partners. She’s known for her ability to foster dialogue and encourage collaboration. “Good design doesn’t happen in a bubble,” she says. “It comes from bringing together diverse perspectives and challenging each other to think differently.” She often goes out of her way to check in with colleagues, especially those who are new to the firm. “Sometimes it’s as simple as asking, ‘How’s it going?’ or, ‘What’s been challenging this week?’” she says. “Those conversations can open the door to growth and learning.”

Mentorship as a Path to Diversity

Amber’s dedication to mentorship in the lighting industry extends beyond the walls of Lam Partners. She recently joined the mentorship program offered by Women in Lighting + Design (WILD) to see what other resources and ideas others may be able to offer. She’s also exploring opportunities to engage with initiatives like Light Justice, an advocacy resource dedicated to addressing inequities in lighting design for the underserved, and recently joined their leadership board as treasurer.

For Amber, mentorship is both a responsibility and a privilege. “It’s about paying forward the opportunities I was given,” she says. While Lam Partners has traditionally attracted a range of talent, Amber is keenly aware of the importance of actively seeking out a variety of voices. This has led her to participate

in career fairs, and also engage with her alma mater through design charettes and teaching opportunities. "I think it’s vital to diversify the pipeline of talent," she says. "Engaging with more communities and institutions can only strengthen the industry as a whole."

Looking Ahead

"Mentorship isn’t static," Amber says. "It’s about being open to learning, even as a mentor, and finding ways to inspire and support others." Over the years, she’s stayed in touch with many of the interns and colleagues she has mentored. "I truly enjoy the chance to engage with them and provide a space for conversation as they navigate their design careers. It’s amazing to see where they go and what they accomplish,” she says.

Amber’s story is a testament to the impact of mentorship in shaping not just careers, but also

the culture of an industry. Her journey, from a curious architect to a seasoned lighting designer and mentor, highlights the importance of fostering environments where learning and growth are celebrated. As she continues to guide others, Amber remains committed to the same values that defined her own path: curiosity, connection, and a passion for lighting. ■

Pharos Architectural Controls

Pharos Architectural Controls is marking its 20th anniversary with a series of initiatives to reflect on its legacy, thank its loyal customers, and highlight its latest advancements. Michael Grosse, Regional Sales Manager for North, Central, and South America, shared insights into the company’s journey and its exciting plans for the future.

Two Decades of Excellence

The story of Pharos is one of innovation and collaboration. Over the past 20 years, Pharos has built a strong reputation for providing high-quality lighting controls that integrate seamlessly with architectural and entertainment projects. The company has developed longstanding relationships with global customers, particularly in North and South America, who rely on its advanced DMX and DALI solutions for their most demanding projects.

Grosse explained, “Our success is rooted in the partnerships we’ve built with OEMs, integrators, and lighting designers who trust us to deliver reliable, innovative products. The support and feedback from our customers have been instrumental in shaping what Pharos is today.”

As part of the anniversary celebrations, Pharos has launched campaigns to highlight these partnerships, including a podcast series. The campaign is called ‘10 People, 10 Projects, 20 Years’ and focuses on 10 industry leaders and 10 standout projects that have played a role in the development of Pharos and its

products. The company has also started recognizing customers who’ve been with them for over a decade with custom-made awards designed to resemble the iconic LPC (Lighting Playback Controller).

Expanding the Market

Pharos’s initial focus was on lighting manufacturers bundling their controls with fixtures, ensuring a streamlined user experience. Over time, the market has expanded to include integrators and AV specialists. These professionals are bridging the gap between live entertainment and architectural lighting, bringing Pharos’ solutions to retail, hospitality, and public spaces.

Grosse shared, “As DMX technology became more widely adopted in North America, we saw a demand for better-quality controls in smaller-scale projects. We’ve started working with experienced integrators and brand-agnostic specialists to ensure more projects benefit from our reliable solutions.”

Innovative Products for Modern Needs

Pharos continues to push boundaries with its next-generation products.

• G4 Four-Port DMX Gateway: Designed for smaller installations, this new node provides four DMX outputs while maintaining the high standards of

electrical isolation and self-healing technology found in larger EDN devices. Grosse emphasized, “The G4 protects against up to 277 volts AC, making it ideal for demanding environments like bridges or outdoor installations.”

• D4 DALI Gateway: Supporting four DALI buses, the D4 is tailored for markets where DALI is popular, such as Europe and select U.S. regions. This update caters to projects requiring multiple buses, reducing the need for multiple devices.

• LPC X S3: This latest iteration of Pharos’ flagship controller features updated hardware, including HDMI and DisplayPort connections, and dual audio inputs for timecode synchronization. Its enhanced processing power supports complex projects, ensuring smooth operation even under demanding conditions.

Looking Ahead

As Pharos grows, the company is planning to open its first U.S. office by 2025. This office will serve as a hub for technical support, training, and servicing. Grosse hopes the move will enhance customer service and streamline logistics for U.S.based clients.

Additionally, he noted the increasing importance of integrators

in the lighting design process. With complex projects requiring seamless integration of controls, Pharos aims to collaborate closely with lighting designers and AV specialists, ensuring the technology complements their creative vision.

A Personal Touch

Grosse’s background in live entertainment and nightclub lighting informs his approach to architectural controls. His hands-on experience enables him to connect with customers on a practical level, ensuring they receive tailored solutions. Reflecting on his role, he remarked, “I enjoy the slower pace of architectural projects compared to live events, but the attention to detail and focus on reliability remain the same.”

The Pharos Philosophy

Pharos’ success lies in its commitment to quality, innovation, and customer relationships. As the company celebrates 20 years, it remains dedicated to pushing the boundaries of what lighting controls can achieve. With a strong product lineup, an expanding market presence, and plans for a U.S. office, Pharos is poised for continued success in the decades to come.

Grosse summed it up best, saying “Our goal is to provide reliable, innovative solutions that empower designers and integrators to bring their visions to life. Here’s to the next 20 years of lighting excellence.” ■

SALONE DEL MOBILE.MILANO International Lighting Forum LAUNCHES THE EUROLUCE

RANDY REID By

The 2025 edition of Salone del Mobile.Milano is set to introduce something groundbreaking for the lighting design community: The Euroluce International Lighting Forum

This inaugural event promises to be a must-attend, bringing together the brightest minds in lighting design, architecture, science, and art for two days of rich discussions and innovation. I’m thrilled to share that I will be there in person to witness this exciting development for our industry.

Taking place on 10-11 April 2025 within the Euroluce exhibition space at Rho Fiera Milano, the Forum will be part of the 63rd edition of Salone del Mobile, which runs from 8-13 April 2025. The Forum marks an essential step in Euroluce’s evolution—one that began during the 2023 edition when organizers reimagined the layout to enhance the visitor experience. This year’s Forum is set to build on that success, offering a platform not just for business, but for the culture of light itself.

At the heart of the Forum is a powerful idea: Light is more than its technological function. It is emotional, philosophical, and an innovative tool for shaping human experiences. The Forum will offer attendees an immersive exploration of light's role as both an expressive and functional language, aiming to redefine future paradigms in lighting design.

A highlight of the event will be its multidisciplinary approach, bringing together creatives, designers, and industry leaders. Among the first confirmed speakers are:

• DRIFT, known for their evocative sculptures and installations blending natural and artificial structures.

• A.J. Weissbard, an internationally acclaimed lighting designer and artist.

• Marjan van Aubel, a trailblazer in sustainable solar design.

• Kaoru Mende, the renowned Japanese lighting designer celebrated for his integration of aesthetics, sustainability, and functionality in architectural and urban lighting.

The structured two-day program will focus on critical themes, including the interaction between light and architecture and light and human wellbeing—issues that are more relevant today than ever.

Maria Porro, President of Salone del Mobile, perfectly captured the spirit of the event, saying: “Light is, incontrovertibly, an increasingly integral part of our lives. The Forum reflects the DNA of the Salone del Mobile.Milano, which has always been a generator and bearer of new ideas and formats for tackling contemporary challenges.” Carlo Urbinati, President of FederlegnoArredo’s Assoluce, added: “Light not only makes things appear, it also creates atmospheres, depths, and perceptions capable of interpreting architectures and open spaces, as in a pentagram. The role of the designer is increasingly similar to that of the conductor of an orchestra.”

As I prepare for this landmark event, I’m excited to see how the Forum will advance lighting design on a global stage. Trade shows like Euroluce have always been about more than product showcases—they are where conversations spark innovation and lasting collaborations are born.

For anyone passionate about lighting, The Euroluce International Lighting Forum is one you won’t want to miss. I’ll be there to cover the event for designing lighting (dl) magazine, and I look forward to seeing many of you in Milan. ■

BDNY 2024

BDNY

Innovative Designs Shine Amid Record-Breaking Attendance

BDNY (Boutique Design New York) continues to be a major industry event for hospitality designers and affiliated professionals. This two-day event attracted over 10,500 industry attendees at the Javits Center in Manhattan and provided a broad range of cutting-edge products, design discussions, and networking events.

Over 700 exhibitors showcased inventive furnishings, lighting, textiles, and more for hotels, restaurants, spas, clubs, cruise ships, and next-gen living interiors. This year’s event was an inspiring showcase for designers, architects, brand leaders, developers, and purchasing agents eager to interact with the industry’s lighting manufacturers and suppliers.

Max Cohen of 2nd Ave Lighting stated, “BDNY is the most relevant national trade show for the hospitality industry these days. This event offers superior custom lighting solutions to make beautiful design statements in boutique hotels, resorts, casinos, and other highly sought-after destinations. We always look forward to this show and the opportunities it presents.”

Bluebird Lighting offered custom and architectural lighting solutions specializing in the hospitality space; Arteriors offered an eclectic selection of lighting with artisanal quality and craftsmanship.

“BDNY has become synonymous with innovation in hospitality’s boutique design sector, offering a unique platform where creativity meets business,” said Keisha Byrd, Vice President and Brand Director, Hospitality Design Group at Emerald. “This year, we’re excited to introduce

Schonbek/Sosh Architects/Bally's Casino Atlantic City, New Jersey

even more interactive elements and leading-edge products that will fuel the creativity of our attendees.”

Sonneman introduced outdoor lighting, under the Inside-Out brand, and Suspenders, an infinitely expandable decorative architectural lighting system.

Harry Moshos, Executive Director of Business Development for WAC Lighting, explained, “WAC, Modern Forms, and Schonbek brands offer products in every lighting category ranging from luxury to upscale to price sensitive and from decorative to ceiling fans to landscape and architectural. We provided a glimpse into our ceiling fan category with our Modern Forms 72” Wynd stainless steel ceiling fan on display, great for marine and coastal environments. We are known for being a reliable running line manufacturer with many in-stock options that benefit our contract and specification customer base.”

Mario Contract Lighting offered a nice array of fine fabric portable lamps, while Oxygen Lighting featured some cool lighted mirrors.

According to David Singer, President of Arc Light Design, "Webster defines 'boutique' as a small shop or company that offers highly specialized services or products. With few exceptions, the majority of exhibitors were not boutiques, but rather offering products and services that were essentially cataloged items— neither bespoke, specialized, unique, nor specifically related to hospitality. It is clear that the ‘boutiqueness’ of a designed project is achieved through the efforts of the designers to use these standard products in a unique and specialized manner."

Arkansas Lighting featured some unique cage-style pendants to complement their handsome portable line, and CA Lighting also exhibited an appealing array of stylish table lamps.

Richard Ancas, President of A&D Projects, Inc. and Ancas Lighting, a sales agency for the industry, explained, "BDNY is one of my favorite shows in NYC. It is well attended by designers and end-users, and more importantly, I always score big projects. It is exceptionally well-run by Paul Bienkowski and his team."

BDNY’s four immersive Designed Spaces, created by leading designers and sponsoring manufacturers, showcased visionary concepts meticulously crafted to inspire and offer a place for attendees to take in intimate panels on top-of-mind topics.

“We dedicated a section of our booth to showcase our custom capabilities with both domestic options for shorter lead times and off-shore options for projects that are price sensitive and with longer runways,” continued Mr. Moshos. “BDNY is one of the premier venues of our industry to meet and network with contract/hospitality customers.”

Secto Design, a Finnish family-owned company, showcased a timeless wooden lighting collection, sustainably handcrafted from certified birch wood.

“As one of the leading trade events for hospitality’s boutique design community, we are thrilled to feature creative content that is inspiring and innovative, including the debut of Dine & Design, a new F&B-focused feature and a robust schedule of talks with industry leaders and up-and-comers. We continue to provide a platform that ignites creativity, starts conversations, highlights the latest trends, and showcases leading-edge products,” said Keisha Byrd.

Some of the many lighting exhibitors included: Coronet, Elegant, FireFarm, Hinkley, Hubbardton Forge, Hudson Valley, Palaceck, and Remington. ■

2nd Ave Lighting/The Kahler Grand Hotel

UP CLOSE WITH GLENN HEINMILLER

It’s best not to make assumptions about Glenn Heinmiller, Partner and Principal at Lam Partners. Glenn’s BA in Theater from Wesleyan University might make one assume theater was his entry point into architectural lighting design, but the path is more nuanced.

“Like a lot of architectural lighting designers,” Glenn said, “you scratch the surface and find an old theater guy (or girl)…I’m one of those. But, it really goes back to my childhood. My dad, trained as an engineer, worked for GE – but in advertising, public relations – so creative endeavors. My mom was an actress and television weather reporter, so that’s the theater part.”

Glenn grew up in a 1952 modernist house his parents built in Schenectady, NY with “very innovative lighting – all kinds of T12 fluorescent valences and homemade fixtures that my dad built, and this GE low voltage control system. I had all that influence, and was interested in technology.

As a pre-teen I would set up light shows for my sister’s parties in the living room – light pulsing to the music. Theater was a way I could apply that interest, so I got into theatrical lighting.”

Moving to Boston after college, Glenn worked as a stagehand and theatrical lighting designer but quickly got involved with laser show production. “It was a crazy industry, doing allnighters, being out of town 100 plus days a year.” Feeling the need for a transition, Glenn started poking around in architectural lighting.

He explained, “It was someplace I could bring my lighting experience and knowledge. I took a continuing ed night class, taught by my now-partner Paul Zaferiou, while still designing

laser shows by day. Eventually I quit my job, and Paul hired me.” Glenn was employee number nine at Lam Partners in 1996, the first hired after founder Bill Lam retired.

Remembering a challenge that taught a lesson in the importance of industry relationships, Glenn recounts, “We were opening a big academic athletic facility, and I get this call that the lenses were falling out of the fixtures. The next three weeks were miserable. What came out of it was that the manufacturer really stepped up. It made me realize the value of relationships that designers and specifiers have with the manufacturers, and with the lighting reps. That’s part of the reason I go to the IALD and IES conferences and to LightFair. In the end, the relationships can be very powerful.”

On issues facing the lighting design community, Glenn expressed two concerns. First, the impact of technology speeding up the creative process of design. He elaborated, “For the last ten plus years, technology has allowed us to work very fast. For any creative process, when you compress the time allowed to do the project too tightly, you don’t have the time to go home at night, sleep, get up the next morning and realize ‘Wait a minute, there’s a better way to do this.’ What we’re trying to do internally in our firm is to make the production of documentation work more efficient, so we have more time for the creative process.”

Glenn’s second issue of industry concern: “The industry has always been starved for sufficient research – fundamental and application/practical research. Circadian lighting is an example. People have done incredible research, and we’re finally getting to the point where we have acceptable metrics, but it’s still kind of vague and nobody knows what to do. It should be a valueadded concept that designers can sell, and that manufacturers can sell, with evidence.”

Reflecting on success, Glenn offered two indicators that he finds meaningful, “One is professional recognition from my peers, and knowing that I’m established in this industry and recognized as a competent lighting designer, as well as being involved in building a business.”

He continued, “Twenty-plus years ago, I’d go to Lightfair and sit in a presentation by Naomi Miller, Jim Benya, Randy Burkett, Nancy Clanton or others, and think, ‘Wow, if only I could do that – these are the gods, they are awesome.’ Fifteen years later, I’m doing a presentation at LightFair (not as awesome as theirs). Now I’m a Fellow of IALD, and I get to sit at the table with these people – and they treat me like a peer!”

Glenn’s second indicator of success “is more local – it’s been very satisfying to me, that I get to work surrounded by supertalented, great people. I learn from everybody. Ten years ago, I was more involved in the management of the firm and was the point person for recruiting. We all learned how important it was to find the right people. They are the ones who inspire us today.”

Asked what advice he would offer to those new to the lighting design community, Glenn is firm, saying, “Don’t ever stop learning. You went to school for lighting, got the degree, got the job – that doesn’t mean you know everything. Don’t just do your job and go home. There are so many other things you can do –go to the IALD conference or a local meeting, get involved with the IES. My biggest contribution has been getting involved with the energy codes (LEED rating system, WELL Building Standard) – I learned so much along the way!”

Clearly enjoying pushing the bounds of assumptions when asked what he does for fun, Glenn smiled, “People who know me a bit think of me as a fairly quiet guy, but I am a big fan of NHRA Professional Drag Racing – which is a very red neck, gearhead kind of thing. You’re watching the cars go from standing start to 340 mph in a thousand feet, in under four seconds. In person, it’s a visceral experience, sensory overload.” Look for the unassuming Glenn Heinmiller next April at the four-wide drags at the Charlotte Motor Speedway! ■
