The Lighting Controls Academy is pleased to announce it has updated its popular Education Express course, EE201: Daylight-Responsive Lighting Controls, now available at NEMA Academy.

Based on an updated version of EE201: Daylight-responsive Lighting Control, a course in NEMA Academy, this article describes a process for designing and applying lighting control solutions that utilize daylight-responsive lighting controls.

In this four-part series, Charles Knuffke, Systems VP & Evangelist, Wattstopper/Legrand, North and Central America and past chair of the Lighting Controls Association provides a crash Lighting Controls 101 class for lighting practitioners.

The California Lighting Technology Center (CLTC) recently released an updated Daylight Harvesting for Commercial Buildings guide. This publication provides guidance towards meeting and exceeding California’s 2019 energy code for daylight harvesting.

The Lighting Controls Association (LCA) has updated EE201: Daylight-Responsive Lighting Control, a popular course in its free, 24/7 Education Express program.

We’re still finding ways to take full advantage of daylight’s benefits. It’s a challenging issue, leaving daylight in an uneasy battle with electric light for brightening our spaces – ignored or underrated in lighting designs, and poorly controlled to boot. Fortunately, this is starting to change. Along with the growing awareness of the WELL, LEED, and BREEAM building standards — which incorporate a variety of recommendations for daylight exposure and control — and acceptance of building codes that support more use of daylight harvesting, there’s a greater incentive to embrace daylight as part of the overall lighting design of a space.

In 2018, the California Lighting Technology Center (CLTC) published “Daylight Harvesting for Commercial Buildings Guide,” a best practices guide to designing daylight harvesting systems. While focused on compliance with California’s tough energy code, the information has broad application.

Synapse recently published an online article providing guidance on how to implement daylight harvesting control strategies.

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.

The California Lighting Technology Center recently announced publication of the Daylight Harvesting for Commercial Buildings Guide, which provides guidance towards meeting and exceeding California’s Building Energy Efficiency Standards for daylight harvesting.

The Illuminating Engineering Society, in partnership with the Lighting Controls Association, has published LEM-7, Lighting Controls for Energy Management, a detailed guide to energy-saving lighting controls. The publication was written by Craig DiLouie, LC in support of the IES Energy Management Committee. The 48-page 8.5×11 guide, which is available for $35 (IES members) and $50 [...]

In a recent study, the Energy Center of Wisconsin monitored several daylighting systems in Minnesota and Wisconsin and analyzed the results of commissioning those systems. The researchers concluded: “Energy modeling, with its assumption of ideal control, appears to have the potential of being an accurate predictive tool for highly effective (>75%) control systems. However, the [...]

Lighting accounts for about a third of electrical energy consumption in commercial buildings. As advanced energy-saving lighting controls still have a minority penetration in the existing building stock, building owners have a major opportunity to reduce energy costs with lighting control. Adoption of advanced lighting controls faces the usual hurdles affecting all energy-efficient lighting, including [...]

Because of the strong energy savings potential offered by daylight harvesting, coupled with advancing technology, codes and standards are now beginning to address daylight harvesting—specifically, International Energy Conservation Code (IECC) 2009, ASHRAE/IES 90.1-2010, ASHRAE 189.1 and Title 24-2008.

What are the benefits of combining advanced lighting control strategies in the same space? Are the energy-saving benefits of lighting controls persistent over time? Can advanced lighting controls be successfully applied to open offices given concerns about jurisdiction conflicts, lighting uniformity, etc.? Can they enhance worker satisfaction? A new office lighting field study addresses these questions. Involving about 90 workers in a real-world open-office environment, the one-year study determined that occupancy sensing, daylight harvesting and individual occupant dimming control worked together in the building to produce average energy savings of 47% while correlating with higher occupant environmental and job satisfaction. The study demonstrates that sophisticated lighting control strategies can be combined successfully to generate persistent, large energy savings in open-plan offices while improving occupant satisfaction with their jobs and workspace.

The study revealed that only 25 percent of the sidelighting photocontrol systems in the studied buildings were functioning well, whereas almost 100 percent of the toplighting photocontrol systems were found to be functioning well in the previous study. What went wrong?

The Weidt Group conducted a study of daylight harvesting projects to find out if daylight harvesting projects are living up to their expectations. The team—consisting of Eijadi, Prasad Vaidya, Tom McDougall, Jason Steinbock and Jim Douglas—reviewed dozens of completed projects, most of which were sidelit using windows, and separated the success stories—some of them operating for 25 years—from projects they considered to be failures.
