LBNL Estimates Average Energy Savings for Popular Lighting Control Strategies

05/21/2012 by Craig DiLouie Leave a Comment

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 […]

Daylight Zones: Toplighted Spaces

11/21/2011 by Lighting Controls Association 2 Comments

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 […]

Daylight Zones: Sidelighted Spaces

10/12/2011 by Craig DiLouie Leave a Comment

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 […]

Learn About Daylighting

08/09/2011 by Lighting Controls Association Leave a Comment

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.

Energy Standards Take On Daylight Harvesting

06/13/2011 by Craig DiLouie Leave a Comment

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.

Photosensors: Technology and Major Trends

12/23/2009 by Craig DiLouie 1 Comment

Daylight harvesting’s value proposition is fairly simple: As daylight levels increase in a space, electric light levels can be automatically reduced to maintain a target task light level and save energy. All automatic daylight harvesting control systems need a device that can measure light levels and signal a controller to dim or switch the lights in response to daylight contribution. This device is called a photosensor. The photosensor is a small device that can include a light-sensitive photocell, input optics and an electronic circuit used to convert the photocell signal into an output control signal, all within a housing and with mounting hardware.
