In this webinar, Energy Center of Wisconsin experts discuss their research findings from monitoring and commissioning several daylighting control systems in Minnesota and Wisconsin. Field performance results are shared and guidelines for successful execution, startup and commissioning of these systems are addressed. Check it out here.
The Daylighting Collaborative at the Energy Center of Wisconsin has announced a free webinar, “Implementation of Successful Daylighting Control Systems,” which will be held Thursday, February 28, 2013, from 1–2:30 PM Central. The webinar will be presented by Scott Schuetter, PE, LEED AP BD+C and Scott Hackel, PE, LEED AP, Senior Energy Engineers at the […]
ECO-STRUCTURE has published an article by industry educator Craig DiLouie, LC on the topic of daylight harvesting. Read it here.
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 […]
Last month at LightingControlsAssociation.org, we published an article about how to establish daylight zones in sidelighted (windowed) building spaces. We looked at an industry rule of thumb and then how the latest generation of energy codes and standards address it. In review, when designing an energy-saving daylight harvesting control system, a critical decision is to […]
When designing an energy-saving daylight harvesting control system, a critical decision is to establish lighting control zones, identifying lighting loads to be separately controlled. Before this decision can be made, however, we must first determine the daylight zones. A daylight zone, also called the daylight area (expressed in square feet), is defined by the ASHRAE/IES […]
The Lighting Controls Association is pleased to announce that it has updated EE201: Introduction to Lighting Control, a popular offering in the Association’s Education Express series of online distance education courses about lighting controls. The course, authored by Craig DiLouie, principal of ZING Communications, Inc. and LCA’s Education Director, provides an introduction to daylight harvesting […]
As sunlight scatters through the atmosphere, it turns the entire sky dome into a daylight source. The proper use of daylight coupled with thoughtful electric lighting design and control applications can significantly reduce energy used by lighting. The ALG Online (Advanced Lighting Guidelines) devotes an entire chapter to understanding the impacts of daylight on commercial spaces and effective ways to integrate daylighting strategies into low-energy building designs.

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.
Lighting Controls Association members will present “Design of Electric Controls for Daylighting,” a three-hour workshop, during the Daylighting Institute at LIGHTFAIR 2011.
