Adolescents can be chronically sleep deprived because of their inability to fall asleep early in combination with fixed wakeup times on school days. According to the Centers for Disease Control, almost 70 percent of school children get insufficient sleep: less than 8 hours on school nights. This type of restricted sleep schedule has been linked ...
"Imagining the Lowline," a free exhibition in Manhattan's Lower East Side showcased Arup's research into a proposal for the world's first underground park. The exhibit, September 15-24, demonstrated how the team's daylighting system for collecting sunlight and channeling it belowground could create an attractive public space and enable plant ...
The US General Services Administration released two reports as part of the Green Proving Ground program, unveiling technologies that reduce energy use in federal buildings and have significant savings potential if widely implemented. The two studies released evaluate plug load controls and an occupant-responsive lighting controls system. GSA ...
It’s a rare event when one technological breakthrough can have far-reaching effects in fields as diverse as stage lighting, horticulture, entomology, energy management, and potentially, space colonization. Penn State researchers from theater arts and horticulture have collaborated with the Office of Physical Plant (OPP) to fine-tune lighting for ...
Researchers from Berlin have published an 878 megapixel aerial mosaic image of Berlin at night. With one pixel per square meter, the resulting map is the highest resolution image ever published of a city at night. Ecologists from the Leibniz Institute of Freshwater Ecology and Inland Fisheries and physicists from Freie Universität Berlin used the ...
Less than a year after showcasing the 152 lumens-per-watt concept LED lamp, this summer Cree, Inc. delivered a new performance benchmark with the 170 lumens-per-watt (LPW) prototype LED lamp. The innovations behind the high-performance 170 LPW LED lamp are enabling significantly higher efficacy and lower cost for Cree’s luminaire portfolio and ...
Individuals with Alzheimer’s disease and related dementias (ADRD) often sleep during the day and are awake at night. The situation can turn life-threatening if they leave their homes and wander around outside. This irregular sleep schedule and night wandering, and the consequent burden on their caretakers, is a primary reason individuals with ...
Stanford University has awarded nine faculty seed grants totaling $2.2 million for promising new research in clean technology and energy efficiency. Among the campus organizations funded, the Precourt Energy Efficiency Center (PEEC) – the umbrella organization for energy research and education at Stanford – will explore “The Dynamic Effects ...
Daylight acts on our body clock and stimulates the brain. Researchers at Fraunhofer, Europe’s largest application-oriented research organization, have worked with industry partners to develop a coating for panes of glass that lets through more light. Above all, it promotes the passage through the glass of those wavelengths of light that govern ...
Solid state lighting, the LED in particular, has advanced to become a promising light source because of its ability to save energy and money, reduce environmental pollutants, and provide custom, quality lighting. This advancement could not have been achieved without industry collaboration. This year, the Lighting Research Center at Rensselaer ...
