Lighting/Daylighting


Designing with Tunable White Light

National Lighting Bureau, 2017 Lighting Forum Video.
https://nlb.org/designing-with-tunable-white-light/

"One of the most important applications for tunable white light will occur in health-care facilities, especially for patients dealing with dementia and Alzheimer’s Disease. By using light as a stimulant during morning hours, patients will nap less during the day, enabling them to sleep better at night. Using light in this way can also reduce the patients’ agitation. In commercial applications, tunable white light can be used to affect the colors of surfaces in a space. This gives building owners the ability to provide lighting that is highly compatible with a given tenant’s interior design, and to adjust the lighting to make it ideally suited for the next tenant’s interior design, avoiding the need to replace the existing system for each new tenant."

"Museums employ two key strategies for lighting works of art: daylighting and artificial or electric lighting. For the Whitney Museum of American Art in New York City, architects Cooper Robertson and Renzo Piano Building Workshop collaborated extensively with Arup consulting engineers, as well as museum curators and conservators, to design suitable solutions for both imperatives."

Legal-Weed Buzz Fades For Utilities

"With local restrictions on marijuana easing across the U.S., power suppliers from California to Maine were expecting a little buzz of their own from newly legitimate pot farmers. After all, a 5,000-square-foot warehouse filled with hydroponic growing systems can draw five times the electricity of a typical industrial user. But after an initial jolt in electricity use, when western states began legalizing marijuana cultivation and sales, demand has fallen off in some areas, according to utilities and analysts."

"Lighting controls allow buildings to achieve significant savings in well-designed daylighted facilities. However, if these systems are not installed properly, notably occupancy sensors, a portion of these potential savings will be squandered. The solution: commission said sensors."

More than half of that growth is expected to take place in North America."
