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?
The Internet of Things (IoT) has become the talk of technologists everywhere, on every product level imaginable. Lighting is no exception. Understanding why this is such an energetic field requires thinking beyond conventional control and connectivity models. The integration of smart features opens the door to intelligent utilization of data and energy that cannot be achieved using closed, localized technologies that cannot be accessed beyond their limited utilitarian functionality.
In August 2018, the California Lighting Technology Center (CLTC) published a best practices guide for designing daylight harvesting lighting control systems. Titled Daylight Harvesting for Commercial Buildings Guide, it focuses on compliance with California’s Title 24 energy code, though it has broad application.
Craig DiLouie, LC, CLCP recently had the opportunity to interview Jonathan Cartrette, Systems Architect, Wattstopper/Legrand for an article that will be published in 2019 for ELECTRICAL CONTRACTOR. The topic? Lighting and cybersecurity.
In September, California passed SB-327, a cybersecurity law that will affect manufacturers of Internet of Things (IoT) and operational technology (OT) devices.
This article at Eaton’s THE SOURCE website provides an insightful look at how connected lighting can facilitate space optimization.
In August 2018, the DesignLights Consortium (DLC) released Energy Savings Potential of DLC Commercial Lighting and Networked Lighting Controls, which projects energy savings for LED commercial lighting and networked lighting controls. The report makes a case that to continue getting big energy savings from lighting for another decade, utility rebate program administrators should transition to supporting LED luminaires and networked controls.
