Just because 0-10V dimmed luminaires are generally lower cost than digitally dimmed luminaires, it should not be assumed there will be a lower price tag on the overall project, writes C. Webster Marsh.
C. Webster Marsh Talks Integration
The U.S. Department of Energy’s (DOE) Integrated Lighting Campaign (ILC) recently interviewed C. Webster Marsh of Penumbra Controls, a lighting controls specialist and frequent contributor to the Lighting Controls Association site.
Is Personal Control the Best Mitigator of Visual Discomfort?
In a recent LD+A energy column, Willard L. Warren, PE, LC points out that various glare metrics have come and gone, with CIE’s Unified Glare Rating (UGR) on the way. The IES Handbook, however, calls such predictors useful for groups but not for individuals. He poses the question: Is it more practical to simply provide dimmable task/ambient lighting system that’s individually controllable?
Lighting and Grid-Interactive Buildings
In A National Roadmap for Grid-Interactive Efficient Buildings, DOE outlines its national goal to triple the energy efficiency and demand flexibility of buildings by 2030. A subsequent report, published in December 2019, specifically evaluates the potential for lighting and electronics (primarily consumer plus IT equipment) to optimize energy efficiency and comfort while providing services back to the grid. This article examines lighting’s potential to support grid interactivity, primarily in the form of networked lighting controls and automated demand response.
0-10V Wire Colors to Change
0-10V dimming wires, the wires used to communicate dimming intensity via a 10-volt signal, can be easily identified on wiring diagrams, installation instructions, and dimmable drivers by their colors: gray and violet (although violet is often referred to as purple). This will soon change, however, as new codes and guidelines take effect.
Steve Mesh Talks Control for COVID Mitigation
Unless you’ve been living on a deserted South Pacific island prior to March 2020, you know that COVID has been the biggest issue facing mankind in the past year and a half. You also know that lots of people, governments and industries have developed methodologies and technology to mitigate the effects and spread of COVID. What do these things mean for lighting control?
Leviton’s David Buerer Talks Plug Load Control
Lighting industry journalist and educator Craig DiLouie, LC, CLCP recently had the opportunity to interview David Buerer, Director of Product Management, Leviton Manufacturing Co., Inc. for an article about plug load control, which will be published in the October 2021 issue of tED Magazine, the official publication of the NAED. Transcript follows.
C. Webster Marsh Talks Written Specifications
Most new construction projects have various forms of documentation, but construction documentation often falls into one of two categories: Drawings or Specifications.
A Year with Networked Lighting Control
In this article published by BUILDING OPERATING MANAGEMENT, building owners and managers are introduced to networked lighting control and shown examples of what pulling data from the system can do to solve business problems.
The IoT and Lighting Design
The Illuminating Engineering Society (IES) recently published ANSI/IES LP-12-21, IoT Connected Lighting. This 43-page Lighting Practice and American National Standard provides guidance for lighting professionals to consider and evaluate connected lighting and Internet of Things (IoT) solutions and applications.
