PG&E is sponsoring a free live webinar featuring some of the top experts in the country on the future of smart buildings. It is titled Lighting and Smart Buildings: Opportunities, Case Studies, & Better Practices. It will present a history, overview, and a report on the current state of building controls integration. The webinar will [...]

David recently reviewed two separate case studies about Fitness Center lighting and was struck by how different the two approaches were.

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.
