Case Studies from Various Industries
At Acuity Brands, we strive to improve and enhance the well-being of the communities we live, work and sell into, through thoughtful lighting and controls solutions.
One of the core benefits of lighting is to support safe and secure buildings and public spaces. Emergency lighting and exit signs from Acuity Brands contribute to helping protect human life in emergency situations by directing occupants to areas of egress as well as providing temporary lighting if and when the power goes out. Designed and engineered by our industry experts with features like cutting-edge LED optics, self-diagnostics and the latest battery technology, we offer life safety products that deliver outstanding performance for interior and exterior applications.
Lighting solutions are often selected based on aesthetics and energy efficiency, but superior optical control is also critical to provide the right light, to the right location, at the right time.
For interior lighting applications, Acuity lighting brands such as Aculux®, Gotham®, Indy™, Mark Architectural Lighting™, Peerless® and Winona® offer luminaires with superior optical performance, multiple light distributions and precise light placement to create visually pleasing and comfortable work, learning or entertainment environments. In addition, many of our luminaires offer multiple color temperature choices including static white and static color, dynamic color, tunable white and dimming to further enhance a space.
For outdoor lighting applications, superior glare control improves visibility and comfort, while enhancing safety and security. Low glare outdoor lighting solutions include refined optical design and controls to ensure that the proper amount light is delivered for effective visibility, while avoiding harsh lighting in public areas such as parking decks and pathways, or windshield glare on streets and roadways. And with additional wired or wireless lighting controls, the outdoor space can adapt to changing visual or security requirements throughout the nighttime hours. Acuity Brands offers outdoor solutions through its American Electric Lighting®, Antique Street Lamps™, Holophane®, Hydrel® and Lithonia Lighting® brands.
With an outdoor lighting application, a major consideration is how the lighting solution impacts the immediate environment, including the visibility of the nighttime sky as a result of light pollution, or light trespass of unwanted light onto neighboring properties. Several Acuity Brands outdoor lighting solutions are designed specifically to minimize light trespass and promote the preservation of the nighttime sky.
LED outdoor area lighting luminaires are designed to direct light for specific optical patterns for applications such as parking lots and plazas with no uplight. The optics also provide options for “forward throw” distribution to minimize light trespass onto neighboring properties, such as when a retail parking lot is adjacent to residential areas. While LED luminaires often appear brighter and a cooler color than traditional technologies, the Acuity Brands solutions are available with a variety of lumen output modules and color temperature to match requirements for application needs. Lower color temperature LEDs, such as 3000K may result in less light scatter in the nighttime sky, reducing the effect of light pollution.
In addition to superior luminaire optics, lighting controls play a critical role in minimizing unwanted or unnecessary nighttime lighting. Because activity levels and visual requirements change throughout the nighttime hours, controls can be used to detect occupancy levels and adjust to lower lighting levels when there is no activity late at night. Solutions are utilized to automatically reduce lighting at a scheduled time late at night after retail areas have closed and lighting is only needed for security purposes. More robust control solutions can monitor and adjust lighting based on traffic patterns, scheduled events or holidays.
We are learning more each year about the non-visual impacts of lighting. Lighting can impact mood, focus alertness, productivity and even circadian rhythm. The relationship between artificial lighting and human physiology – alertness, sleep, immune function and more – is becoming increasingly clear. The human circadian system utilizes light to tell our bodies when to be active and when to rest. Shift work or social activities when the body typically is designed to rest can cause a disruption to this circadian rhythm resulting in sleep disruption and potentially other medical issues. There are positive impacts when lighting is used to entrain consistency in the circadian cycle as well – such as alertness, focus and responsiveness.
Acuity Brands provides solutions that promote humanistic design criteria for healthcare, offices, education and other applications with the use of controls and color tuning. Using the tunable white feature, spaces can be designed to promote intellectually stimulating learning environments and promote alert and rest times in schools and in healthcare facilities.
Daylight is also an important criterion for humanistic lighting. Daylight integration through windows or skylights with our Sunoptics® daylight delivery systems add natural light to supplement the electric lighting. With daylight integration, the electric lighting system can be controlled to manage the intensity and color to blend with the natural light providing an optimal solution.
Our Smart Room Control Solution from Distech Controls® provides the ability to manage daylight integration, lighting and shade control to achieve the higher levels of comfort for occupants while increasing energy savings. The research evaluating non-visual impacts of lighting is still an emerging field. Acuity Brands is proud to be a sponsor of scientific research in this field through the Jim H. McClung Lighting Research Foundation.

Title 20 is a part of the California Code of Regulations and are appliance efficiency standards that require the manufacturer of certain regulated products to certify that the devices meet minimum standards — among them certain energy efficiency thresholds. Title 20 also restricts the sale of non-compliant products within the state of California. Most LED luminaires are not regulated by Title 20, but the list of regulated devices include a number of lighting products, including portable luminaires (e.g. shop lights), exit signs, metal halide luminaires, LED downlight retrofit with ANSI base adaptor, and small battery chargers used for battery backup.
Acuity Brands certifies its products that have been tested by a CEC approved lab and meet the Title 20 requirements. Products meeting the certification provisions are listed in the CA T20 Appliance Efficiency Database or Modernized Appliance Efficiency Database System (MAEDBS).
Title 24 of the California Code of Regulations are California’s Energy Efficiency Standards for Residential and Nonresidential Buildings. It is California’s Energy Code and part of the California Building Standards Code, covering new construction of, and additions and alterations to, residential and nonresidential buildings. The 2019 Code was adopted May 9, 2018 and is effective on January 1, 2020.
Under the revision of Title 24, Joint Appendix (JA8) provides the qualification requirements for high efficacy light sources. JA8 took effect in January 2017 for new construction, renovations, and additions to both residential and commercial buildings. JA8 compliant lighting have been approved by the state of California and registered with the California Energy Commissions (CEC).
