PRESIDENT'S MESSAGE

A FEW PARTING THOUGHTS As I sat in my office and began thinking about writing this message, a few thoughts and cliches came to mind.

Time flies when you’re having fun.

All good things come to an end.

And, in reflection, they really sum up my feelings as I write this message and realize that this is my last one. (No applause, please!)

But, seriously, time really does fly and in the blink of an eye two years have passed; but what a two years they have been!

• Major shifts/transitions in our industry, • rapidly advancing technology, • the advancement of IoT, • the impact of controls as a main driving force, • the drive toward data collection and analysis, • introduction of a new, industry-first certification, the Certified Lighting Controls Professional (CLCP), and • the first NALMCO virtual conference in response to the entire economy being shut down in the face of the COVID-19 pandemic!

But, through it all, your association has endured, and we are continuing to advance the best interests of both our General and Associate members. Thanks to your continued support and participation.

It truly has been an honor to serve with such an outstanding and committed board of directors. Believe me, going forward we are in good hands. I want to express my appreciation to each of the board members for their support and continued commitment to making NALMCO America’s best industry association. I would be remiss if I did not recognize the support and guidance the board and I receive from our strategic partner, Amplify Association Management. Specifically, Heather, Denise and Kelly’s ongoing commitment to NALMCO’s success has been a stabilizing force and beacon of light. We couldn’t have done it without you.

So, it is with mixed emotions that I hand over the gavel to Scott Mendelsohn, CLMC, your incoming president and the new board. You are in good hands!

And, one last comment, my special thanks to Chris Frank, CLMC, for his service and support and guidance to the board and association. He leaves the past president’s position and prepares for some well-earned downtime.

Thank you, Chris.

Thank you for a great run, Bill Sgro, CLMC, CLCP NALMCO President bsgro@ecoengineering.com

As for all good things come to an end, I can’t tell you how proud I have been to have earned your support to serve as president of NALMCO. It is one of the highlights of my career. Thank you!

RON GILCREASE, NALMCO PAST PRESIDENT, RETIRES

NALMCO Past President Ron Gilcrease announced his retirement effective December 31, 2020.

Most recently, Gilcrease was the vice president of national accounts with XtraLight. Ron is a staunch supporter of NALMCO and has demonstrated his commitment through many years of service.

Here are a few lessons Ron learned along the way.

Your reputation is built by promises kept. People with good intentions make promises. People with good character keep them.

Developing a personal relationship with your clients and understanding their needs is the key to success in any continuing relationship sales environment. I’m not a transaction salesperson; I’m a relationship salesperson.

Being a transactional salesperson means closing the sale today. A relationship-based sale approach means closing scores of wins over years because of earned trust and respect.

Your spouse is your partner in success. Much of my career has required me to be available seven days a week and 24 hours a day and involved traveling over 100

LM&M | December 2020

MEMBERSHIP RESOURCES nights a year. While that’s great for frequent flier miles and free hotel nights, it can be damaging to relationships and your real life. I am grateful that my wife has always had the patience and support to handle our real-life issues when I wasn’t able to do so. I have been able to focus my efforts on my career only because she’s always focused on keeping our home, daughter and personal life balanced.

Work ethic is best trained by example. My dad was always an inspiration to me because of his unfailing optimism and incredible work ethic. He retired from a successful career at age 59 and reinvented himself in his second career. He told me when he was 81 that he had decided to work only half time! He said the challenge was trying to figure out which 12 hours each day he was going to take off.

The quality of the time is more important than the quantity of the time. I was 37 years old when my wife and I decided to adopt our daughter. I was concerned how I would fit being a father into my life, but it was the greatest decision of my life! I’ve found that setting aside time that was just for her made a huge difference in helping overcome the times we could not be together. All the times I’ve shared only with her have created a strong father-daughter bond.

Members may contact Ron through December 31, 2020, at Ron.Gilcrease@SolisUSA.com

Pick your partners carefully—bad partnerships can be like bad marriages. In my early career I entered into a partnership and, over time, found that my partner did not share my work ethic, values and vision. It was an experience I learned from, but would never want to repeat. Take time to make sure the relationship is right before taking the plunge into the financial and emotional commitment that opening and running a business together entails. Divorcing a partner can be an expensive and disruptive distraction in your business.

Listen more and judge less. I’ve always been passionate about business and particularly about taking care of clients. That passion sometimes had unintended consequences—especially in my earlier career, I was often impatient with co-workers and was not as forgiving or supportive as I should have been. I wish I’d learned to be kinder earlier in life.

Be active in your industry. Industry participation is rewarding personally and professionally. Many of those I served with have become lifelong friends, and the relationships I developed have been a large part of any success I’ve enjoyed in my career.

Have a little fun every day. Life is short and we spend so much of it at work. Make some time to enjoy your coworkers, your clients and your vendors. Share a meal, a sporting event or special trip. Make memories with these important people in your life.

CIRCADIAN LIGHTING GUIDE

BY CRAIG DILOUIE, CLCP, LC

FUTURE TRENDS & BUSINESS In December 2019, Underwriters Laboratories (UL) declared circadian lighting actionable with publication of Design Guide 24480, Design Guideline for Promoting Circadian Entrainment with Light for Day-Active People.

This 60-page guide details how to design interior lighting systems that promote a more natural pattern of bright days and dim nights, supportive of circadian health.

First, let’s review the basis of circadian-supportive lighting. The body’s circadian system produces and regulates body functions based on 24-hour cycles, or circadian rhythms. Meanwhile, light regulates circadian rhythms, specifically sunrise and sunset, though modern humans spend most of their time indoors, where lighting systems are primarily designed for vision, not light’s non-visual effects. The key components of circadian lighting are intensity, or amount of light falling on the eye’s photoreceptors throughout the day, requiring vertical illumination; spectrum, or the wavelength of the light; timing, or when the light is received by the eye; and duration, or length of time of light exposure.

As our scientific understanding grew, the lighting industry became interested in developing metrics, design practices, and products to realize lighting solutions supportive of circadian health. Then the WELL Building Standard recognized it with a design goalpost; the Lighting Research Center (LRC) produced its own metric and design templates; the Illuminating Engineering Society began work on an ANSI recommended practice; and UL formed a task force headed by the LRC’s Dr. Mark Rea to produce design guidance (not a UL standard).

In its simplest form, the guide says day-active people need more light during the day and less at night, with resulting circadian stimulus measured using the LRC’s Circadian Stimulus (CS) metric. The guide requires the practitioner to consider not only the visual effect of lighting but consider vertical illumination delivered to the eye. Supported by design examples, its six steps include: #1: Establish a goal. The guide recommends a minimum CS of 0.3, which indicates a sufficient quantity of illumination falling on the eye’s photoreceptors for a minimum of two hours during occupied daytime hours.

For additional support, CS is stepped down to a maximum of 0.2 in the evening and 0.1 at night. #2: Choose the luminaire. This is mostly centered on light distribution. The higher the vertical-to-horizontal ratio (EV/ EH)—requiring sufficient vertical illumination—the more likely a suitable higher CS will be produced. Daylight is ideal. All lighting should not produce objectionable glare.

#3: Select the light source. The guide recommends selecting a light source that will produce a suitable spectral power distribution (SPD), which can be gained from the manufacturer or measured with a spectroradiometer. #4: Calculate vertical illumination. The above information and reflectances is entered into software such as CAD or AGi32 to produce a representative range of vertical light levels. #5: Calculate circadian stimulus. Calculate CS using the online calculator at www.LRC.RPI.edu/cscalculator. #6: Ensure the CS is 0.3+. If the design fails to meet this goal, consider luminaires with an indirect distribution and/ or placed in or nearer the workstation.

Publication of this guide suggests circadian-supportive lighting is now actionable. Agreement with that relates to how much faith one has in the LRC metric and underlying science. The industry agrees on the basic premise, that more light during the day and less light at night is supportive of circadian response, as this promotes a more natural pattern. What may be argued is in the details—metrics and design approaches. For the most part, it depends on whether the customer has that faith, particularly in existing buildings, where a retrofit can become more complex by attempting to adapt a traditional lighting system focused on horizontal illumination to one that produces sufficient vertical illumination.

Lighting management companies may wish to become generally familiar with UL’s guidance by checking out the digital version for free, or purchase it for use for $402.

COLOR RESEARCH

BY CRAIG DILOUIE, CLCP, LC

FUTURE TRENDS & BUSINESS Despite its limitations, the color rendering index (CRI) endured as a lasting measure of color fidelity in light sources. A rule of thumb is an 80+ CRI is considered “good” for many commercial applications such as office buildings and schools. A 90+ CRI, meanwhile, is considered “excellent” for discerning applications such as groceries and retail.

The biggest limit of CRI is it measures only fidelity—the average of how eight test colors appear for a light source compared to an ideal reference source—but not chroma or hue. This results in two light sources having the same CRI but possibly a different gamut (increase or decrease in chroma)—e.g., one being oversaturated in blue and the other in yellow, resulting in objects and the space looking different under each source.

In 2015, the Illuminating Engineering Society (IES) announced TM-30-15, a technical memorandum that unveiled a new method for evaluating color in light sources. In 2018, a new and improved version was released. TM-30 measures both color fidelity and gamut.

Fidelity is measured using a metric called Rf, analogous to CRI but based on 99 color samples. Gamut is measured using Rg. TM-30 also provides for color vector graphics that visualize average hue and chroma shifts.

level of preference correlated with fidelity being 75+ with a 2-16 percent oversaturated in the red spectrum and overall saturation. The WELL Building Standard adopted similar TM-30 measures (Rf 78+, Rg 100+, 1-15 percent red oversaturation), with an alternative being either >90 CRI or >80 CRI coupled with an R9 of >50.

After the PNNL study, a similar study was conducted

by Penn State University. In this study, the researchers similarly kept the light source at 3500K while varying fidelity and gamut, but showed the participants only one lighting scene per day. Despite the different methodology, preferred light sources fell within the same parameters as the PNNL study. PNNL subsequently conducted a follow-up study in which they varied chromaticity from 2700K to 4300K, and again achieved similar results for preference.

Lighting upgrades provide the ability not only to provide comfortable vision at the highest level of energy efficiency, but also enhance overall occupant satisfaction with the space being illuminated. TM30 provides a tool with which lighting management companies can evaluate the color performance of light sources with much greater precision. Further, research provides the basis for ensuring light sources are selected that produce sufficient red saturation.

Why is TM-30 important? While CRI may have traditionally been seen as convenient and sufficient, research suggests fidelity alone is not enough to do the job, and that fidelity is actually less important than gamut in predicting human color preference. CRI also does not indicate saturation in red, which studies also suggest is a key element in human color preference.

In one such study published by the Pacific Northwest National Laboratory in 2016, participants entered a room filled with common items—fruit, clothes, a mirror to view skin tones, and more—all illuminated at 3500K in a series of lighting scenes. Each scene received light with a different spectral power distribution, with variations in fidelity and with color gamut ranging from under to oversaturated. The participants then rated each scene.

The researchers found that color gamut, not fidelity, was most strongly linked to preference. More specifically, saturation in red was found to be important.

This resulted in a simple equation: Preference = Fidelity + Red Saturation. The researchers concluded a high LM&M | December 2020

PROJECT SPOTLIGHT

EIKO PROVIDES FAST AND EFFICIENT LIGHTING SOLUTION FOR NEWLY BUILT HORSE BARN Submitted by NALMCO Associate Member EiKO Pro Electric LLC had a customer that had just constructed a new horse barn and was looking to light it quickly. The barn was designed to be lit with 10 high bay lights for maximum efficacy and efficiency. Together with EiKO’s distributor partner, Platt Electric Redmond located in Redmond, Oregon, Pro Electric selected the EiKO 200W BAY-C high bay fixture, which puts out an impressive 30,000+ lumens at a 5000K color temperature. This high lumen output and the long life of the fixture—72,000 hours—made it an ideal choice for the application.

A Safe and Secure Environment for Horses, Riders, and Care Givers Obviously, when lighting a barn, the security and safety of the animals, riders and care givers is paramount. EiKO’s LED high bay products fill the space with light, eliminating shadows and blind spots. Thanks to the advantageous confluence of availability, price and specifications, this product was purchased and installed within 24 hours, allowing the barn to be used immediately. In fact, the facility is so well lit, effectively creating a bright, clean visual aesthetic, that two additional customers have requested the product for their own projects.

IOENERGY AND SNAPCOUNT – IOT PROJECT SPOTLIGHT Submitted by NALMCO Associate Member SnapCount Overview When IoEnergy was awarded the opportunity to implement smart lighting into a 32-year-old building, they knew an accurate assessment and precise proposal would be a key component to a successful project. Using the SnapCount retrofit platform and implementing the latest and greatest in smart lighting, IoEnergy was able to implement a smart lighting network with a three-year payback period.

Background IoEnergy is an energy efficiency services company, focusing on saving clients money through energy cost reduction. Through implementing enterprise-wide savings, IoEnergy goes beyond simply installing LEDs, completing deep retrofit projects including Internet of Things (IoT) integration. With over 25 years of experience in the lighting efficiency industry, the IoEnergy team was no stranger to auditing facilities with pencil and paper, afterwards transposing the notes into Excel or Google Sheets, and even considered building their own internal software. In 2017, IoEnergy was referred to SnapCount as a means to help complete deep retrofit projects in a more accurate manner with a professional output.

The Project ARM, a multinational semiconductor and software design company, was experiencing a problem in their San Jose offices that is very familiar to office buildings built in the last 20 to 30 years. Outdated and inefficient fluorescent lights that were operating on simple sensors and lighting controls, ultimately proving to be cost-ineffective and non-interactive. Recognizing the opportunity to turn the 32-year-old building into an intelligent building, ARM chose to work with IoEnergy to perform the retrofit.

Using SnapCount to audit the existing fixtures and controls in the building, IoEnergy was able to skip the process of hand-transposing notes to a spreadsheet as they had done prior, and instead focus on providing the customer with a proposal including advanced lighting and IoT functionalities. “Working on proposing IoT and advanced lighting in SnapCount versus the old-fashioned method has been night and day. I was able to adjust savings, tweak tunings and more. The proposal and LM&M | December 2020

PROJECT SPOTLIGHT savings calculations we were able to generate was completely defensible to the client with the credibility it provided,” stated Murano.

IoEnergy replaced a total of 971 fluorescent bulbs to energy efficient LED bulbs, as well as install hundreds of sensors in the building, all capable of collecting bits of data 65 times per second in the San Jose office building.

This completely programmable networked lighting system allowed building managers to control areas, rooms and even individual lights. Additionally, the lighting system can change brightness based upon occupancy, and takes advantage of daylight harvesting features from exterior natural lighting.

The Results • Three-Year Payback Period • IoEnergy's smart lighting installation provided ARM with a three-year payback period.

• 32 percent Return on Investment • Implementing efficient LEDs and controls, IoEnergy acheived a 32 percent return on investment for ARM. • $275k Cumulative Avoided Costs • Through the replacement of inefficient lighting and implementing controls, ARM saved $275,000 in costs.

IoEnergy Reaction “Using SnapCount for this project was extremely beneficial. It was easy to input data, and incredibly easy to manipulate the data in our format. We are also thrilled with the professionalism of the output that SnapCount provides and we’re proud to align our brand with the output. With SnapCount, I’m able to do much more on the road than our old retrofit process allowed, and this platform simply makes our company look even more professional,” stated Danny Krueger, CEO of IoEnergy.
