A recent editorial in LD&A magazine noted that we no longer have to single out “LED” lighting projects because now almost all projects use LEDs. There is no question that LEDs have drastically reduced energy use in both new construction and retrofit projects. So much so that some are arguing if we even really need lighting energy codes anymore.

Energy Code Ace has created a summary of California Title 24 code changes for Non-Residential Buildings. The 2022 Title 24, Part 6 Building Energy Efficiency Standards (Energy Code or Title 24, Part 6) updates the 2019 Energy Code.

David recently had the pleasure of interviewing Don Vendetti, CEO of Evluma. The street and area lighting company has just published a new whitepaper about glare. We also discussed the new ANSI/IES RP-8 standard, as well as the trend toward warming CCTs for streetlights.

University of California, Irvine (UCI) researchers conducted a thorough examination of peer-reviewed literature on the most prevalent mental health disorders and found that circadian rhythm disruption (CRD) is present in nearly all of them. However, correlation is not causation, so it is not clear if the mental disorders cause circadian disruption, if circadian disruption causes mental disorders or both in a positive feedback loop.

The Journal of Post-Acute and Long-Term Care Medicine (JAMDA) recently published a research study showing long-term care facility falls were reduced 43% by changing light spectrum and intensity throughout the day for residents.

In a newly published study, researchers from Binghamton University’s Thomas J. Watson College of Engineering and Applied Science answer many of the questions about UV disinfection of the virus that causes COVID-19, and lay the foundation for health standards about what offers true disinfection.

There is growing scientific evidence that LED outdoor white light at night is devastating global insect and bird populations, in addition to potential negative human health impacts. A possible solution is to move back to non-white lighting, such as phosphor-converted amber and direct emission amber LED sources, outdoors.

The COVID-19 pandemic showed just how important focusing on health and wellness is (and will be) for facility managers and construction professionals. A new report from the Urban Land Institute titled “Greening Buildings for Healthier People” examines all the ways resilience, health and wellness, and sustainability match up.

Korrus is the company that owns Ecosense, Soraa, Scuva, Tempo Industries, and now Circadian ZircLight. They focus on “Human Light Interaction (HLI),” which they define as seeking to understand human interactions with light, and creating technologies that better serve the needs of those humans.
