LEDs Magazine recently published an article by Jurgen Hase, VP of machine-to-machine competence at the Deutsche Telekom, in which Hase describes a trend among cities to adopt networked lighting control. These lighting control systems allow remote control and operation of streetlighting systems for significant benefits–not only energy savings and improved maintenance of the lighting, but […]
2014 Lighting Controls Association Satisfaction Survey
We asked, you answered. The Lighting Controls Association recently conducted a survey of regular site users (subscribers to the LCA newsletter, lightingCONTROL) to determine how well we’re doing our job and what kinds of features you might like to see developed in the 2015. Results are based on 110 respondents, which were filtered to 86 […]
KW Engineering Publishes Whitepaper Proposes BAS-Lighting Control Integration for Existing Buildings
A new whitepaper by KW Engineering, “Beyond Advanced Lighting Controls: Reaching Net Zero with Integrated Building Controls” (James Donson, Jon Schoenfeld and Bruce Chamberlain), identifies advanced lighting controls (networked lighting) as a major contributor to energy cost savings for existing buildings. The paper states that greater savings for both lighting and HVAC systems can be […]
NEMA Updates LSD 64-2014 Lighting Controls Terminology
The National Electrical Manufacturers Association (NEMA) recently updated LSD 64-2014 Lighting Controls Terminology. This white paper, which was originally published in 2012, was updated to clarify terminology related to daylight responsive controls. NEMA LSD 64 defines terminology related to controls for lighting systems for non-residential and residential applications. The goal of LSD 64 is for […]
5 Ways to Make Your Lighting Retrofit Easier and More Cost Effective
Guest post by Brent Protzman, PhD, CEM, LEED GA, LC Protzman is the Manager of Energy Information & Analytics at Lutron Electronics Lighting retrofits, layered with advanced control strategies can improve occupant comfort, enhance productivity, deliver greater building efficiencies and often result in lighting electricity savings up to 60% or more. New light sources, specifically […]
Jim Brodrick on Dimming LEDs with Phase-Cut Dimmers
Republication of Postings from the U.S. Department of Energy (DOE) Solid-State Lighting Program by Jim Brodrick, SSL Program Manager, U.S. Department of Energy You may recall that last year, DOE’s GATEWAY program released a report entitled Dimming LEDs with Phase-Cut Dimmers: The Specifier’s Process for Maximizing Success, which was created in response to issues raised […]
What’s New in ASHRAE/IES 90.1-2013
Update: On September 26, 2014, the U.S. Department of Energy (DOE) named the ASHRAE/IES 90.1-2013 energy standard as the new national energy reference standard, superseding the 2010 version in effect until then. Within two years, all states in the United States must put into effect a commercial building energy code at least as stringent as […]
Outdoor Lighting Controls: The State of the Art
Outdoor lighting controls is undergoing a mini-revolution that offers new design and selling opportunities while challenging electrical professionals to stay on top of technological change. Traditionally, outdoor lighting control was relatively simple. A typical scheme featured a controller providing automatic ON/OFF based on time of day (using an astronomical time switch) or daylight (photosensor). The […]
DOE Publishes CALiPER Report on Dimming, Flicker and Power Quality Characteristics of LED PAR38 Lamps
The U.S. Department of Energy’s CALiPER program has released Report 20.2, which is part of a series of investigations on LED PAR38 lamps. Report 20.2 focuses on dimming, flicker and power quality characteristics evaluated with a single dimmer. The dimming, flicker and power quality behavior of the LED PAR38 lamps evaluated in this study was […]
Visible Light Communication
Visible light communication (VLC) is a wireless method that uses light emitted by LEDs to deliver networked, mobile, high-speed communication similar to Wi-Fi, leading to the term Li-Fi. It can be used as standalone solution or in a supplementary role to radio-frequency (RF) or cellular network communication. The basis of the technology, conceived by Professor […]
