A Breakthrough in Biophilic Lighting Design
Unlike typical hospital rooms, which are lit solely from above, the light from the Lightglass clerestories feels like daylight because it is coming from the side of the room; outdoors the sun is only directly overhead for a short period each day, and our eyes are more sensitive to light from the sides. Lighting from the vertical plane, like that from Lightglass luminous clerestories, color-tuned or not, offers greater impact on circadian rhythm and melatonin suppression than light from above and can help in achieving WELL certification.
“We all need brighter days and darker nights,” says Josh Butz, an electrical engineer with Stantec, who worked on the Children’s Hospital of Philadelphia project. “Lightglass was able to help us achieve the circadian stimulus values throughout the course of the day, because of the added impact of lighting from the vertical plane.”
This ability to mimic natural daylight is a boon to patients, heath care workers, and visitors. By creating a subconscious connection to the outdoors, and a much-needed stochastic stimuli for people who might spend hours without stepping outside, Lightglass makes this hospital feel a little more natural. Jennifer Lanting, an interior designer who worked on the project said, “The Lightglass looked like a real window in the space.”
Constructed like a window, out of aluminum and glass, Lightglass Before the compact window-mimicking light fixture came on the scene, there was no practical way to bring a biophilic lighting solution to the vertical plane. “If we didn’t have Lightglass, I don’t think we would have found another product that worked,” remarked Lanting.
