Networked lighting controls can reduce energy consumption by an average 47 percent, according to a recent industry study. That makes control a powerful tool in managing energy costs, but it only captures a small fraction of its potential value in enhancing quality lighting with LED technology.
The AIA’s semi-annual Consensus Construction Forecast, a survey of the nation’s leading construction forecasters, is projecting 4.4% growth in nonresidential construction spending in 2019 and 2.4% in 2020. This article by Craig DiLouie, LC, CLCP reviews the forecast and leading construction industry economic indicators.
According to a recent research report by the market research and strategy consulting firm, Graphical Research, Europe Smart Lighting Market share will surpass USD $9 billion by 2024.
“Luminaire-Level Lighting Controls” (LLLCs) – this relatively new term in the lighting controls industry indicates that every fixture controlled by a networked lighting control system (NLC) incorporates two specific things: 1) a “controller”, and 2) sensors. This article by Steve Mesh describes the utility and application of this control approach, which is starting to be adopted by model energy codes.
McGuire Engineers’ John Yoon, PE, LEED AP ID+C recently contributed an article to CONSULTING-SPECIFYING ENGINEER citing 10 reasons why lighting controls commissioning may fail. It’s an excellent piece with plenty of helpful observations and guidance.
LUX Magazine recently published an article making a case that Bluetooth Mesh is positioned as a truly transformative protocol, enabling not only lighting control but capabilities far exceeding it.
Synapse recently published an online article providing guidance on how to implement daylight harvesting control strategies.
The LED revolution produced many luminaires with built-in switching and dimming. This facilitated a trend of using the same luminaires for both general and emergency lighting, powered by battery, backup generator, or UPS. This eliminates emergency units but creates a control challenge. The dual-function luminaires must be controllable for energy management and visual needs, while overriding these inputs to power to full brightness during a power failure.
Steve Mesh writes, “According to Wikipedia, a communication protocol is a ‘system of rules that allow two or more entities of a communications system to transmit information via any kind of variation of a physical quantity.’ That’s a mouthful! What does that mean in terms of networked lighting control (NLC) systems?”
Luminaires are becoming smart nodes on powerful data networks. How is this happening and what are the benefits of a sensor-rich network?
