Health and Wellness Strategies Complement Resilience & Sustainability

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.


US EIA Releases 2020 RECS Housing Characteristics With Some Lighting Use Data

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.


Light-Operated Computer Chip Implements All 5 Basic Logic Operations Without Electricity

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.

Circadian Lighting Pioneer Says The Science Isn’t Ready Yet

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.
