Interesting article about lighting controls and the Internet of Things in this article by ARCHITECTURAL LIGHTING.
LED lighting has made a new dimension of lighting control, color tuning, widely available. By mixing separately dimmable arrays of warm- and cool-white, saturated colors (RGB+A) or a mix of the two, correlated color temperature (CCT) can be tuned manually or automatically based on various application needs. Besides CCT, the source’s color rendering index (CRI) […]
Alumage Advisors has released its latest LED Smart Lighting Report, including a free version for end-users, highlighting 40 product features of interest for 1,000 commercial and industrial (C&I) luminaires worldwide. “Since introducing our first reports in 2013, we added a smart lighting focus, as 77% of the products we track are dimmable, 59% offer motion […]
The California Lighting Technology Center has produced a new report covering the current state of retail lighting and the extraordinary energy savings potential that can be achieved with adaptable lighting control systems. From CLTC: “To address the slow adoption of adaptive lighting solutions in the retail sector, researchers developed and demonstrated an optimized retail lighting […]
A traditional lighting control design deploys manual switches and simple controls such as load scheduling to control large zones of luminaires. Even when occupancy sensors are installed, these devices are typically assigned to large control zones. Increasingly stringent commercial building energy codes have made control zoning more granular. Emerging control strategies such as daylight harvesting […]
According to a new market research report by Markets and Markets, Home Automation and Control Market by Lighting Control (Occupancy Sensors, Relays, Transmitters), Security & Access Control (Video Surveillance, Biometric), HVAC Control (Heating & Cooling Coils, Pumps & Fans, Sensors), and Geography – Global Forecast to 2020, the home automation market is expected to grow […]
In an article recently published by LEDs Magazine, Lutron Electronics’ Roland Ledyard explains that while 0-10V dimming is a standard driver feature, every technology decision has a cost. He makes an argument that digitally addressable drivers are often a more economical decision. Click here to read the article.
LCA: How would you characterize current and future demand for lighting controls in existing commercial buildings? Knuffke: It is fragmented. While I travel around the country for work, I live in the Bay Area, so I’ve got a very California-based viewpoint of the situation. The new provisions in California’s Title 24 requires more controls in […]
Occupancy sensors are a proven strategy to reduce lighting energy consumption. As such, they are mandated by commercial building energy codes. Current codes require a maximum 30-minute time delay. Time delay is a field-adjustable setting that determines the amount of time between last detected occupancy and the lights switching or dimming. Newer codes may reduce […]
BUILDING OPERATING MANAGEMENT Magazine recently published an article about recommissioning lighting control systems. I was happy to be interviewed and contribute to the article. Research suggests retroactive commissioning can generate real energy savings and maximize the performance and value of installed equipment. Check it out here.
