The International Dark-Sky Association (IDA) released the “Artificial Light at Night: State of the Science 2022” report, earlier this month. It is a high-level overview of the best scientific understanding of how artificial light at night affects the nighttime environment. It finds the world transformed by electric light in less than 150 years since its introduction.

Research conducted in 2020 indicates that the control of light impacts indoor environmental quality (IEQ)-productivity belief more than other IEQ control.

Enlighted, A Siemens Company has publicly released a partial version of Verdantix’s new whitepaper, Green Quadrant: IoT Platforms for Smart Buildings 2022.

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.

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.

The US EIA that releases the data is part of the US DOE. The 2020 Residential Energy Consumption Survey (RECS) provides household characteristics and energy usage indicators for the estimated 123.5 million homes in the United States in 2020.

The demand for next-generation computers that can quickly calculate and process a lot of information is rapidly increasing. A logic device is a circuit that obtains an output value by applying one or more logic inputs to certain logic operation (AND, OR, etc.). A logic circuit can be made by combining a plurality of electronic transistors.

Mark Halper has an interesting article in LED’s Magazine interviewing Russell Foster, the scientist who predicted the non-visual receptors in the eye that are involved in the circadian response to light (pRGCs / ipRGCs). He says circadian lighting science isn’t ready yet, and there are too many unknowns.

On March 17th, 18 circadian lighting researchers published a “consensus view” of circadian lighting recommendations, titled: Recommendations for daytime, evening, and nighttime indoor light exposure to best support physiology, sleep, and wakefulness in healthy adults, in the journal PLOS Biology. The authors include well-known circadian lighting researchers, George Brainard and Steven Lockley.
