Energy_Woes_With_Wireless_Lighting_25497.aspx


"Commercial buildings in the United States have an installed base of 2.1 billion lamps—80% of which are linear fluorescent lamps. Despite the fact that lighting control strategies, including dimmers, occupancy sensors, timers, daylighting controls, and energy management systems (EMS), are acknowledged to yield very significant energy savings, fewer than 31% of these lamps are associated with any type of lighting controls in the field (Ashe et al. 2012)."

Rethinking Daylighting [in Schools]

High Performing Buildings, Spring 2014, by Robert Anthony Hans & Kenny Stanfield.
http://www.hpbmagazine.org/File%20Library/Case%20Studies/Spring%202014/030-037_LED.pdf

"When designers of the first net zero energy school in the U.S. considered how they would approach the lighting design differently using today’s LED technology, the results extended far beyond just switching out the lightbulbs. The hypothetical redesign of Richardsville (Ky.) Elementary classrooms involves rethinking the daylighting design based on the evolution of LED lighting and the cheaper cost of photovoltaics (PV)."
