A survey of two groups of professionals describing themselves as electrical contractors and energy consultants, conducted by the Lighting Controls Association from its lightingCONTROL newsletter database, suggests automatic lighting controls are becoming more popular in lighting retrofits. Respondents reported lighting controls were considered in over 50 percent and installed in over 30 percent of their […]
ELECTRICAL CONTRACTOR has published an article by Craig DiLouie describing how to zone lighting control strategies and develop a control zone plan. Check it out here.
The Lighting Controls Association is pleased to announce that EE105: Lighting Control System Design has been added to the Association’s popular online Education Express distance education courses. Residing here, Education Express provides in-depth education about lighting control and controllable ballast technology, application, system design and commissioning, as well as meta-issues such as commissioning, energy codes, […]
Lighting quality is a critical consideration in effective lighting design, and often should take priority over energy savings and the economies of cost. But what is lighting quality? It goes beyond energy and cost and light levels to include brightness, light distribution, color, aesthetics, daylight, ease of use for controls, and other issues. While many […]
As demand for lighting controls continues to grow, advanced solutions are becoming increasingly specified while also becoming increasingly sophisticated. This increasing sophistication translates to greater owner benefit but can also pose greater risk of design and installation mistakes. In a perfect world, designers create clear and detailed lighting control requirements that are easily installed by […]
In May 2011, Correctional News published “Lighting Controls Provide Green Benefits” by Joshua Slobin, which describes the energy-saving and resulting sustainability benefits of advanced lighting controls. Get the full story here.
The U.S. Department of Energy (DOE) has unveiled the Commercial Lighting Solutions for Office webtool. Available free at www.lightingsolutions.energy.gov, CLS for Office provides customizable lighting and control templates enabling building owners to generate more than 30% lighting energy savings compared to office buildings complying with prevailing energy codes.
The National Electrical Manufacturers Association (NEMA) launched the Premium Ballast program to identify the industry’s most efficient fluorescent fixed-output and dimmable electronic T8 ballasts, thereby providing a mechanism for market recognition and specification of these products.
In this special report by the Lighting Controls Association, we will describe bi-level switching code requirements, its role in the Commercial Buildings Deduction, methods and equipment, and the results of a study of typical energy savings achievable with bi-level switching in popular applications.
Indoor spaces with high ceilings, such as factories, warehouses, big box retail stores, gymnasiums and all-purpose rooms are often lighted by probe-start metal halide lighting systems. At higher ceiling heights, 350W and 400W units are common …
Advancements in lamp and ballast technology have resulted in two alternatives to this basic system that can significantly reduce energy consumption while providing other benefits. The first alternative is fluorescent T8 or T5HO hi-bay fixtures, which can replace probe-start metal halide fixtures in retrofit or new construction for energy savings up to about 50%. The second alternative is pulse-start metal halide lamp-ballast systems, which can provide up to 25% energy cost savings in existing applications and up to 30% in capital and operating costs in new construction.
